General Information About Bladder Cancer
Incidence and Mortality
Bladder cancer is the sixth most common cancer in the United States after lung cancer, prostate cancer, breast cancer, colon cancer, and melanoma. It is the fourth most common cancer in men and the eleventh most common cancer in women. Of the roughly 83,000 new cases annually, about 63,000 are in men and about 20,000 are in women. Of the roughly 17,000 annual deaths, more than 12,000 are in men and fewer than 5,000 are in women. The reasons for this disparity between the sexes are not well understood.[1,2]
Estimated new cases and deaths from bladder cancer in the United States in 2024:[2]
New cases: 83,190.
Deaths: 16,840.
Anatomy
The urinary tract consists of the kidneys, the ureters, the bladder, and the urethra. The urinary tract is lined with transitional cell urothelium from the renal pelvis to the proximal urethra. Transitional cell carcinoma (also known as urothelial carcinoma) can develop anywhere along this pathway.
Anatomy of the male urinary system (left panel) and female urinary system (right panel) showing the kidneys, ureters, bladder, and urethra. The inside of the left kidney shows the renal pelvis. An inset shows the renal tubules and urine. Also shown are the prostate and penis (left panel) and the uterus (right panel). Urine is made in the renal tubules and collects in the renal pelvis of each kidney. The urine flows from the kidneys through the ureters to the bladder. The urine is stored in the bladder until it leaves the body through the urethra.
Histopathology
Under normal conditions, the bladder, the lower part of the kidneys (the renal pelvises), the ureters, and the proximal urethra are lined with a specialized mucous membrane referred to as transitional epithelium (also called urothelium). Most cancers that form in these tissues are transitional cell carcinomas (also called urothelial carcinomas) that derive from transitional epithelium. For more information, see Renal Cell Cancer Treatment and Transitional Cell Cancer of the Renal Pelvis and Ureter Treatment.
Transitional cell carcinoma of the bladder can be low-grade or high-grade:
Low-grade bladder cancer often recurs in the bladder after treatment but rarely invades the muscular wall of the bladder or spreads to other parts of the body. Patients rarely die of low-grade bladder cancer.
High-grade bladder cancer commonly recurs in the bladder and has a strong tendency to invade the muscular wall of the bladder and spread to other parts of the body. High-grade bladder cancer is treated more aggressively than low-grade bladder cancer and is much more likely to cause death. Almost all deaths from bladder cancer result from high-grade disease.
Bladder cancer is also divided into muscle-invasive and nonmuscle-invasive disease, based on invasion of the muscularis propria (also known as the detrusor muscle), which is the thick muscle deep in the bladder wall.
Muscle-invasive disease is much more likely to spread to other parts of the body and is generally treated by either removing the bladder or treating the bladder with radiation and chemotherapy. As noted above, high-grade cancers are much more likely to be muscle-invasive than low-grade cancers. Thus, muscle-invasive cancers are generally treated more aggressively than nonmuscle-invasive cancers.
Nonmuscle-invasive disease can often be treated by removing the tumor(s) via a transurethral approach. Sometimes chemotherapy or other treatments are introduced into the bladder with a catheter to help fight the cancer.
Under conditions of chronic inflammation, such as infection of the bladder with the Schistosoma haematobium parasite, squamous metaplasia may occur in the bladder. The incidence of squamous cell carcinomas of the bladder is higher under conditions of chronic inflammation than is otherwise seen. In addition to transitional cell carcinomas and squamous cell carcinomas, adenocarcinomas, small cell carcinomas, and sarcomas can form in the bladder. In the United States, transitional cell carcinomas represent most (>90%) bladder cancers. However, a significant number of transitional cell carcinomas have areas of squamous cell or other differentiation.
Carcinogenesis and Risk Factors
Increasing age is the most important risk factor for most cancers. Other risk factors for bladder cancer include the following:
Neurogenic bladder and associated use of indwelling catheters.[18]
There is strong evidence linking exposure to carcinogens to bladder cancer. The most common risk factor for bladder cancer in the United States is cigarette smoking. It is estimated that up to one-half of all bladder cancers are caused by cigarette smoking and that smoking increases a person's risk of bladder cancer two to four times above baseline risk.[19,20] Smokers with less functional polymorphisms of N-acetyltransferase-2 (known as slow acetylators) have a higher risk of bladder cancer than other smokers, presumably because of their reduced ability to detoxify carcinogens.
Certain occupational exposures have also been linked to bladder cancer, and higher rates of bladder cancer have been reported in textile dye and rubber tire industries; among painters; leather workers; shoemakers; and aluminum-, iron-, and steelworkers. Specific chemicals linked to bladder carcinogenesis include beta-naphthylamine, 4-aminobiphenyl, and benzidine. Although these chemicals are now generally banned in Western countries, many other chemicals still in use are also suspected of causing bladder cancer.[20]
Exposure to the chemotherapy drug cyclophosphamide has also been associated with an increased risk of bladder cancer.
Chronic urinary tract infections and infection with the parasite S. haematobium have also been associated with an increased risk of bladder cancer, often squamous cell carcinomas. Chronic inflammation is thought to play a key role in carcinogenesis in these settings.
Clinical Features
Bladder cancer typically presents with gross or microscopic hematuria. Less commonly, patients may complain of urinary frequency, nocturia, and dysuria, symptoms that are more common in patients with carcinoma in situ. Patients with upper urinary tract urothelial carcinomas may present with pain resulting from obstruction by the tumor.
Urothelial carcinomas are often multifocal—the entire urothelium needs to be evaluated if a tumor is found. In patients with bladder cancer, upper urinary tract imaging is essential for staging and surveillance. This can be accomplished with ureteroscopy, retrograde pyelograms during cystoscopy, intravenous pyelograms, or computed tomography (CT) urograms. Similarly, patients with an upper urinary tract transitional cell carcinoma have a high risk of developing bladder cancer; these patients need periodic cystoscopy and surveillance of the contralateral upper urinary tract.
Diagnostics
When bladder cancer is suspected, the most useful diagnostic test is cystoscopy. Radiological studies such as CT scans or ultrasound do not have sufficient sensitivity to be useful for detecting bladder cancers. Cystoscopy can be performed in a urology clinic.
If cancer is seen on cystoscopy, the patient is typically scheduled for bimanual examination under anesthesia and a repeat cystoscopy in an operating room so that transurethral resection of the tumor(s) and/or biopsies can be performed. If a high-grade cancer (including carcinoma in situ) or invasive cancer is seen, the patient is staged with a CT scan of the abdomen and pelvis (or CT urogram) and either a chest x-ray or chest CT scan. Patients with a nonhepatic elevation of alkaline phosphatase or symptoms suggestive of bone metastases undergo a bone scan.
Prognostic Factors
The major prognostic factors in carcinoma of the bladder are the following:
Depth of invasion into the bladder wall.
Pathological grade of the tumor.
Presence versus absence of carcinoma in situ.
Among nonmuscle-invasive cancers, the following factors are also prognostic:[21]
Number of tumors.
Tumor size (e.g., >3 cm or <3 cm).
Invasion of the lamina propria (Ta vs. T1).
Whether the tumor is the primary tumor or a recurrence.
Most superficial tumors are well differentiated. Patients in whom superficial tumors are less differentiated, large, multiple, or associated with carcinoma in situ (Tis) in other areas of the bladder mucosa are at greatest risk of recurrence and the development of invasive cancer. These patients may be considered to have the entire urothelial surface at risk of cancer development.
Survival
Patients who die of bladder cancer almost always have disease that has metastasized from the bladder to other organs. Low-grade bladder cancers rarely grow into the muscular wall of the bladder and rarely metastasize, so patients with low-grade (grade I) bladder cancers very rarely die of their cancer. Nonetheless, they may experience multiple relapses that need to be resected.
Almost all deaths from bladder cancer are among patients with high-grade disease, which has a much greater potential to invade deeply into the bladder's muscular wall and spread to other organs.
Approximately 70% to 80% of patients with newly diagnosed bladder cancer will present with superficial bladder tumors (i.e., stage Ta, Tis, or T1). The prognosis of these patients depends largely on the grade of the tumor. Patients with high-grade tumors have a significant risk of dying of their cancer even if it is not muscle-invasive.[22] Among patients with high-grade tumors, those who present with superficial, nonmuscle-invasive bladder cancer can usually be cured, and those with muscle-invasive disease can sometimes be cured.[23,24,25] Studies have demonstrated that some patients with distant metastases have achieved long-term complete response after being treated with combination chemotherapy regimens, although most such patients have metastases limited to their lymph nodes and have a near-normal performance status.[26,27]
There are clinical trials suitable for patients with all stages of bladder cancer. Whenever possible, patients should consider clinical trials designed to improve upon standard therapy.
General information about clinical trials is also available from the NCI website.
Follow-Up
Bladder cancer tends to recur, even when it is noninvasive at the time of diagnosis; therefore, standard practice is to perform surveillance of the urinary tract after a diagnosis of bladder cancer. However, no trials have been conducted to assess whether surveillance affects rates of progression, survival, or quality of life; nor have clinical trials defined an optimal surveillance schedule. Urothelial carcinomas are thought to reflect a so-called field defect whereby the cancer emerges because of genetic mutations that are widely present in the patient's bladder or entire urothelium. Thus, people who have had a bladder tumor resected often subsequently have recurrent tumors in the bladder, often in different locations from the site of the initial tumor. Similarly, but less commonly, they may have tumors appear in the upper urinary tract (i.e., in the renal pelvises or ureters).
An alternative explanation for these patterns of recurrence is that cancer cells that are disrupted when a tumor is resected may reimplant elsewhere in the urothelium. Support for this second theory is that tumors are more likely to recur downstream than upstream from the initial cancer. Upper urinary tract cancers are more likely to recur in the bladder than bladder cancers are to recur in the upper urinary tract.[28,29,30,31]

Cellular Classification of Bladder Cancer
More than 90% of bladder cancers are transitional cell carcinomas derived from the uroepithelium. About 2% to 7% are squamous cell carcinomas, and 2% are adenocarcinomas.[1] Adenocarcinomas may be of urachal origin or nonurachal origin; the latter type is generally thought to arise from metaplasia of chronically irritated transitional epithelium. Small cell carcinomas also may develop in the bladder.[2,3] Sarcomas of the bladder are very rare.
Pathological grade of transitional cell carcinomas, which is based on cellular atypia, nuclear abnormalities, and the number of mitotic figures, is of great prognostic importance.

Stage Information for Bladder Cancer
The clinical staging of carcinoma of the bladder is determined by the depth of invasion of the bladder wall by the tumor. This determination requires a cystoscopic examination that includes a biopsy and examination under anesthesia to assess the following:
Size and mobility of palpable masses.
Degree of induration of the bladder wall.
Presence of extravesical extension or invasion of adjacent organs.
Clinical staging, even when computed tomographic (CT) and/or magnetic resonance imaging (MRI) scans and other imaging modalities are used, often underestimates the extent of tumor, particularly in cancers that are less differentiated and more deeply invasive. CT imaging is the standard staging modality. A clinical benefit from obtaining MRI or positron emission tomography scans instead of CT imaging has not been demonstrated.[1,2]
AJCC Stage Groupings and TNM Definitions

Treatment Option Overview for Bladder Cancer
Nonmuscle-Invasive Bladder Cancer
Treatment of nonmuscle-invasive bladder cancers (Ta, Tis, T1) is based on risk stratification. Essentially all patients are initially treated with transurethral resection (TUR) of the bladder tumor followed by a single immediate instillation of intravesical chemotherapy (mitomycin is typically used in the United States).[1,2,3,4,5,6,7]
Subsequent therapy is based on risk and typically consists of one of the following:[6,7,8,9]
Surveillance for relapse or recurrence (typically used for tumors with low risk of recurrence or progression).
A minimum of 1 year of intravesical treatments with bacillus Calmette-Guérin (BCG) plus surveillance for relapse (typically used for tumors at intermediate or high risk of progression to muscle-invasive disease).
Additional intravesical chemotherapy (typically used for tumors with a high risk of recurrence but low risk of progression to muscle-invasive disease).
Muscle-Invasive Bladder Cancer
Standard treatment for patients with muscle-invasive bladder cancers whose goal is cure is either neoadjuvant multiagent cisplatin–based chemotherapy followed by radical cystectomy and urinary diversion or radiation therapy with concomitant chemotherapy.[10,11,12,13] Other treatment approaches include the following:
Radical cystectomy followed by multiagent cisplatin–based chemotherapy.
Radical cystectomy without perioperative chemotherapy.[14,15,16]
Radiation therapy without concomitant chemotherapy.[17]
Partial cystectomy with or without perioperative chemotherapy.[18]
Many patients newly diagnosed with bladder cancer are candidates for participation in clinical trials.
Reconstructive techniques that fashion low-pressure storage reservoirs from the reconfigured small and large bowel eliminate the need for external drainage devices and, in many patients, allow voiding per urethra. These techniques are designed to improve the quality of life for patients who require cystectomy.[19]

Fluorouracil Dosing
The DPYD gene encodes an enzyme that catabolizes pyrimidines and fluoropyrimidines, like capecitabine and fluorouracil. An estimated 1% to 2% of the population has germline pathogenic variants in DPYD, which lead to reduced DPD protein function and an accumulation of pyrimidines and fluoropyrimidines in the body.[20,21] Patients with the DPYD*2A variant who receive fluoropyrimidines may experience severe, life-threatening toxicities that are sometimes fatal. Many other DPYD variants have been identified, with a range of clinical effects.[20,21,22] Fluoropyrimidine avoidance or a dose reduction of 50% may be recommended based on the patient's DPYD genotype and number of functioning DPYD alleles.[23,24,25]DPYD genetic testing costs less than $200, but insurance coverage varies due to a lack of national guidelines.[26] In addition, testing may delay therapy by 2 weeks, which would not be advisable in urgent situations. This controversial issue requires further evaluation.[27]

Treatment of Stage 0 Bladder Cancer
Treatment Options for Stage 0 Bladder Cancer
Patients with stage 0 bladder tumors can be cured by a variety of treatments, even though the tendency for new tumor formation is high. In a series of patients with Ta or T1 tumors who were followed for a minimum of 20 years or until death, the risk of bladder cancer recurrence after initial resection was 80%.[1] Of greater concern than recurrence is the risk of progression to muscle-invasive, locally-advanced, or metastatic bladder cancer. While progression is rare for patients with low-grade tumors, it is common among patients with high-grade cancers.
One series of 125 patients with TaG3 cancers followed for 15 to 20 years reported that 39% progressed to more advanced-stage disease while 26% died of urothelial cancer. In comparison, among 23 patients with TaG1 tumors, none died and 5% progressed.[2] Risk factors for recurrence and progression are the following:[2,3,4,5,6]
High-grade disease.
Presence of carcinoma in situ.
Tumor larger than 3 cm.
Multiple tumors.
History of prior bladder cancer.
Treatment options for stage 0 bladder cancer include the following:
Transurethral resection (TUR) with fulguration followed by an immediate postoperative instillation of intravesical chemotherapy.
TUR with fulguration.
TUR with fulguration followed by an immediate postoperative instillation of intravesical chemotherapy followed by periodic intravesical instillations of bacillus Calmette-Guérin (BCG).
TUR with fulguration followed by an immediate postoperative instillation of intravesical chemotherapy followed by intravesical chemotherapy.
Segmental cystectomy (rarely indicated).
Radical cystectomy (in rare, highly selected patients with extensive or refractory superficial high-grade tumors).
Transurethral resection (TUR) with fulguration followed by an immediate postoperative instillation of intravesical chemotherapy
TUR and fulguration are the most common and conservative forms of management. Careful surveillance of subsequent bladder tumor progression is important. Because most bladder cancers recur after TUR, one immediate intravesical instillation of chemotherapy is often given after TUR. Numerous randomized controlled trials have evaluated this practice, and a meta-analysis of seven trials reported that a single intravesical treatment with chemotherapy reduced the odds of recurrence by 39% (odds ratio [OR], 0.61; P < .0001).[7,8] However, although a single instillation of chemotherapy lowers the relapse rate in patients with multiple tumors, most still relapse. Such treatment is insufficient by itself for these patients.
One retrospective series addressed the value of performing a second TUR within 2 to 6 weeks of the first TUR.[9][Level of evidence C3] A second TUR performed on 38 patients with Tis or Ta disease revealed that nine patients (24%) had lamina propria invasion (T1) and three patients (8%) had muscle invasion (T2).[9]
Such information may change the definitive management options in these individuals. Patients with extensive multifocal recurrent disease and/or other unfavorable prognostic features require more aggressive forms of treatment.
Evidence (TUR with fulguration followed by immediate postoperative instillation of intravesical chemotherapy):
A 2004 meta-analysis of seven randomized controlled trials (1,476 patients with stage Ta or stage T1 bladder cancer) compared TUR alone with TUR followed by a single immediate intravesical instillation of chemotherapy.[7]
The relapse rate was 48% for patients who received TUR alone and 37% for patients who received TUR plus intravesical chemotherapy (OR, 0.61; P < .0001). The risk of recurrence declined for patients with single (OR, 0.61) or multiple (OR, 0.44) tumors, but 65% of those with multiple tumors relapsed despite intravesical chemotherapy.
Agents studied included epirubicin, mitomycin (MMC), thiotepa, and pirarubicin.
A subsequent multicenter randomized controlled trial confirmed the reduction in risk of recurrence. A study that included 404 patients reported a relapse rate of 51% for patients who received epirubicin immediately after TUR and 63% for patients who received placebo immediately after TUR (P = .04). However, only small recurrences were prevented in this study, drawing into question the magnitude of benefit.[10]
Similarly, another multicenter randomized controlled trial confirmed the reduction in risk of recurrence. One study randomly assigned patients (N = 305) to receive either an instillation of epirubicin or no further treatment after TUR.[8]
The relapse rates were 62% for patients who received epirubicin and 77% for patients in the control arm (P = .016).
The hazard ratio for recurrence was 0.56 (P = .002) with epirubicin. However, the main benefit was seen in patients at lower risk of relapse. Among patients at intermediate or high risk of relapse, the relapse rates were 81% with epirubicin versus 85% with no further treatment (P = .35).
TUR with fulguration followed by an immediate postoperative instillation of intravesical chemotherapy followed by periodic intravesical instillations of BCG
Intravesical BCG is the treatment of choice for reducing the risk of cancer progression and is mainly used for cancers with an intermediate or high risk of progressing.[6,11,12,13] An individual patient meta-analysis of randomized trials compared intravesical BCG with intravesical MMC. The meta-analysis reported that there was a 32% reduction in risk of recurrence with BCG but only when the BCG treatment included a maintenance phase whereby BCG was given periodically for at least 1 year (typically an induction phase of six weekly treatments followed by three weekly treatments every 3 months).[12] Intravesical chemotherapy is tolerated better than intravesical BCG.[14,15,16,17,18] Although BCG may not prolong overall survival for Tis disease, it appears to afford complete response rates of about 70%, thereby decreasing the need for salvage cystectomy.[17] Studies show that intravesical BCG delays tumor recurrence and tumor progression.[18,19]
Intravesical therapy with thiotepa, MMC, doxorubicin, or BCG is most often used in patients with multiple tumors or recurrent tumors or as a prophylactic measure in high-risk patients after TUR.[20,21,22]
Evidence (TUR with fulguration followed by an immediate postoperative instillation of intravesical chemotherapy followed by periodic intravesical instillations of BCG):
Intravesical chemotherapy
Three meta-analyses of randomized controlled trials that compared TUR alone with TUR followed by intravesical chemotherapy reported that adjuvant therapy was associated with a statistically significant increase in time to recurrence.[23,24,25] No advantage has been shown with respect to survival or prevention of progression to invasive disease or metastases.
Intravesical BCG with maintenance BCG treatments
An individual patient meta-analysis of nine randomized trials (2,820 patients with Ta or T1 bladder cancer) that compared intravesical BCG with intravesical MMC was published.[12]
Among trials in which the BCG treatment included a maintenance component, there was a 32% reduction in risk of recurrence (P < .0001) compared with MMC. BCG was associated with a 28% increase in the risk of recurrence when there was no maintenance BCG administered compared with MMC.
There were no differences in progression or death.[12]
A meta-analysis of nine randomized controlled trials (2,410 patients) that compared intravesical BCG with MMC was published.[26]
Progression was observed in 7.67% of the patients who received BCG and 9.44% of patients who received MMC at a median follow-up of 26 months (P = .08).
When the analysis was limited to trials in which the BCG arm included a maintenance component, the progression rate was significantly lower in the patients who received BCG (OR, 0.66; 95% confidence interval, 0.47–0.94; P = .02).
A meta-analysis of the published results of nine randomized controlled trials that compared intravesical BCG with intravesical chemotherapy in 700 patients with carcinoma in situ of the bladder was published.[11]
With a median follow-up of 3.6 years, 47% of the BCG group had no evidence of disease and 26% of the chemotherapy group had no evidence of disease.
BCG was superior to MMC at preventing recurrence only when maintenance BCG was part of the treatment.
A controlled trial evaluated 384 patients randomly assigned to induction intravesical BCG or induction intravesical BCG followed by maintenance intravesical BCG.[27]
The median recurrence-free survival was 36 months without maintenance BCG and 77 months in the maintenance arm (P < .0001). The risk of disease worsening (progression to T2 or greater disease, use of cystectomy, systemic chemotherapy, or radiation therapy) was greater in the induction arm than in the maintenance arm (P = .04).
The 5-year overall survival rate was 78% in the induction arm versus 83% in the maintenance arm, but this difference was not statistically significant.
BCG is associated with a risk of significant toxicity, including rare deaths from BCG sepsis. Compared with MMC, BCG produces more local toxicity (44% with BCG vs. 30% with MMC) and systemic side effects (19% with BCG vs. 12% with MMC). Because of concerns about side effects and toxicity, BCG is not generally used for patients with a low risk of progression to advanced-stage disease.[6,26]
Segmental cystectomy (rarely indicated)
Segmental cystectomy is rarely indicated.[22] It is indicated for relatively few patients because of the tendency of bladder cancer to involve multiple regions of the bladder mucosa and to occur in areas that cannot be segmentally resected. Moreover, cystectomy (whether segmental or radical) is generally not indicated for T0 bladder cancer (see radical cystectomy below).[28,29]
Radical cystectomy (in rare, highly selected patients with extensive or refractory superficial high-grade tumors)
Radical cystectomy is used in selected patients with extensive or refractory superficial tumors,[2,30,31] based on reports that up to 20% of patients with Tis will die of bladder cancer. However, cystectomy (whether segmental or radical) is generally not indicated for patients with Ta or Tis bladder cancer. Patients at high risk of progression, typically those with recurrent high-grade tumors with carcinoma in situ after intravesical therapy with BCG, should consider radical cystectomy.[32,33,34,35]

Treatment of Stage I Bladder Cancer
Treatment Options for Stage I Bladder Cancer
Patients with stage I bladder tumors are unlikely to die of bladder cancer, but the tendency for new tumor formation is high. In a series of patients with Ta or T1 tumors who were followed for a minimum of 20 years or until death, the risk of bladder recurrence after initial resection was 80%.[1] Of greater concern than recurrence is the risk of progression to muscle-invasive, locally-advanced, or metastatic bladder cancer. While progression is rare for low-grade tumors, it is common among high-grade cancers.
One series of 125 patients with TaG3 cancers followed for 15 to 20 years reported that 39% progressed to more advanced stage disease, while 26% died of urothelial cancer. In comparison, among 23 patients with TaG1 tumors, none died and 5% progressed.[2] Risk factors for recurrence and progression include the following:[2,3,4,5,6]
High-grade disease.
Presence of carcinoma in situ.
Tumor larger than 3 cm.
Multiple tumors.
History of prior bladder cancer.
Treatment options for stage I bladder cancer include the following:
Transurethral resection (TUR) with fulguration followed by an immediate postoperative instillation of intravesical chemotherapy.
TUR with fulguration.
TUR with fulguration followed by an immediate postoperative instillation of intravesical chemotherapy followed by periodic intravesical instillations of bacillus Calmette-Guérin (BCG).
TUR with fulguration followed by an immediate postoperative instillation of intravesical chemotherapy followed by intravesical chemotherapy.
Segmental cystectomy (rarely indicated).
Radical cystectomy (in selected patients with extensive or refractory superficial tumors).
TUR with fulguration followed by an immediate postoperative instillation of intravesical chemotherapy
TUR and fulguration are the most common and conservative forms of management. Careful surveillance of subsequent bladder tumor progression is important. Because most bladder cancers recur after TUR, one immediate intravesical instillation of chemotherapy after TUR is widely used. Numerous randomized controlled trials have evaluated this practice, and a meta-analysis of seven trials reported that a single intravesical treatment with chemotherapy reduced the odds of recurrence by 39% (odds ratio [OR], 0.61; P < .0001).[7,8]
TUR with fulguration
Staging a bladder cancer via TUR is based on the extent of invasion. To assess whether cancer has invaded the muscle, muscularis propria must be present in the resected tissue. While a repeat TUR is generally considered mandatory for T1 and high-grade noninvasive bladder cancers if no muscularis propria is present in the resected tissue from the first TUR, many experts recommend that a second TUR be routinely performed within 2 to 6 weeks of the first TUR to confirm staging and achieve a more complete resection. The rationale for this derives from numerous findings, including the following:
The risk of local recurrence after TUR is high.
Residual cancer is often found when a repeat TUR is performed.
More-advanced–stage cancer is sometimes found with repeat TUR.
Patients undergoing radical cystectomy for nonmuscle-invasive bladder cancer are often found to have T2 or greater disease when the cystectomy specimen is examined.
A substantial number of patients with high-grade nonmuscle-invasive bladder cancer subsequently die of their disease.
Evidence (routine repeat TUR):
A review of more than 2,400 patients from over 60 different institutions reported a 3-month recurrence rate of roughly 14% to 20% after TUR, while a literature review reported that up to 10% of patients who underwent a second TUR for Ta to T1 cancer were upstaged to T2.[9] The likelihood of being upstaged to T2 is much higher when no muscularis propria is present in the initial TUR tissue.[10]
One retrospective series of 38 patients with Tis or Ta disease who underwent a second TUR found that nine patients (24%) had lamina propria invasion (T1) and three patients (8%) had muscle invasion (T2).[11]
A subsequent study from a different institution reported that among 214 patients with Ta to T1 cancers who underwent a second TUR, 27% of Ta and 37% of T1 patients had residual cancer detected.[12]
A review of other published papers reported that residual tumor was present in 27% to 62% of cases, and muscle-invasive disease was discovered in 1% to 10% of case series with at least 50 patients.[10]
Repeat TUR has not been shown to reduce relapse rates or prolong survival, but there is a clear rationale for seeking accurate staging information on which to base treatment decisions. Such information may change the definitive management options for patients and identify patients who are more likely to benefit from more aggressive treatment.
TUR with fulguration followed by an immediate postoperative instillation of intravesical chemotherapy followed by periodic intravesical instillations of BCG
Intravesical BCG is the treatment of choice for reducing the risk of cancer progression and is mainly used for cancers with an intermediate or high risk of progressing.[6,13,14,15] An individual patient meta-analysis of randomized trials that compared intravesical BCG with intravesical mitomycin (MMC) reported that there was a 32% reduction in risk of recurrence with BCG but only when the BCG treatment included a maintenance phase whereby BCG was given periodically for at least 1 year (typically an induction phase of six weekly treatments followed by three weekly treatments every 3 months).[14] Intravesical chemotherapy is tolerated better than intravesical BCG.[16,17,18,19,20] Although BCG may not prolong overall survival for Tis disease, it appears to afford complete response rates of about 70%, thereby decreasing the need for salvage cystectomy.[19] Studies show that intravesical BCG delays tumor recurrence and tumor progression.[20,21]
Evidence (immediate intravesical chemotherapy after transurethral resection):
A 2004 meta-analysis of seven randomized controlled trials (1,476 patients with Ta or T1 bladder cancer) compared TUR alone with TUR followed by a single immediate intravesical instillation of chemotherapy. Agents studied included epirubicin, MMC, thiotepa, and pirarubicin.[7]
The relapse rates were 48% for patients who received TUR alone and 37% for patients who received TUR plus intravesical chemotherapy (OR, 0.61; P < .0001). The risk of recurrence declined for patients with single (OR, 0.61) or multiple (OR, 0.44) tumors, but 65% of those with multiple tumors relapsed despite intravesical chemotherapy.
A subsequent multicenter randomized controlled trial confirmed the reduction in risk of recurrence. A study that included 404 patients reported a relapse rate of 51% for patients who received epirubicin immediately after TUR and 63% for patients who received placebo immediately after TUR (P = .04). However, only small recurrences were prevented in this study, drawing into question the magnitude of benefit.[22]
Similarly, another multicenter randomized controlled trial confirmed the reduction in risk of recurrence. One study randomly assigned patients (N = 305) to receive either an instillation of epirubicin or no further treatment after TUR.[8]
The relapse rates were 62% for patients who received epirubicin and 77% for patients in the control arm (P = .016).
The hazard ratio for recurrence was 0.56 (P = .002) with epirubicin. However, the main benefit was seen in patients at lower risk of relapse. Among patients at intermediate or high risk of relapse, the relapse rates were 81% with epirubicin versus 85% with no further treatment (P = .35).
Evidence (intravesical BCG with maintenance BCG treatments):
An individual patient meta-analysis of nine randomized trials (2,820 patients with Ta or T1 bladder cancer) that compared intravesical BCG with intravesical MMC was published.[14]
Among trials in which the BCG treatment included a maintenance component, there was a 32% reduction in risk of recurrence (P < .0001) compared with MMC. BCG was associated with a 28% increase in the risk of recurrence when no maintenance BCG was given compared with MMC.
There were no differences in progression or death.
A meta-analysis of nine randomized controlled trials (2,410 patients) that compared intravesical BCG with MMC was published.[23]
Progression was seen in 7.67% of the patients who received BCG and 9.44% of patients who received MMC at a median follow-up of 26 months (P = .08).
When the analysis was limited to trials in which the BCG arm included a maintenance component, the progression rate was significantly lower in the patients who received BCG (OR, 0.66; 95% confidence interval, 0.47–0.94; P = .02).
A meta-analysis of the published results of nine randomized controlled trials that compared intravesical BCG with intravesical chemotherapy in 700 patients with carcinoma in situ of the bladder was published.[13]
With a median follow-up of 3.6 years, 47% of the BCG group had no evidence of disease and 26% of the chemotherapy group had no evidence of disease.
In this meta-analysis, BCG was superior to MMC at preventing recurrence only when maintenance BCG was part of the treatment.
A controlled trial evaluated 384 patients randomly assigned to induction intravesical BCG or induction intravesical BCG followed by maintenance intravesical BCG.[24]
Median recurrence-free survival was 36 months without maintenance BCG and 77 months in the maintenance arm (P < .0001). The risk of disease worsening (progression to T2 or greater disease, use of cystectomy, systemic chemotherapy, or radiation therapy) was greater in the induction arm than in the maintenance arm (P = .04).
The 5-year overall survival rate was 78% in the induction arm versus 83% in the maintenance arm, but this difference was not statistically significant.
BCG is associated with a risk of significant toxicity, including rare deaths from BCG sepsis. Compared with MMC, BCG produces more local toxicity (44% with BCG vs. 30% with MMC) and systemic side effects (19% with BCG vs. 12% with MMC). Because of concerns about side effects and toxicity, BCG is not generally used for patients with a low risk of progression to more-advanced–stage disease.[6,23]
Evidence (two treatment courses of intravesical BCG):
Two nonconsecutive 6-week courses with BCG may be necessary to obtain optimal response.[25] Patients with a T1 tumor at the 3-month evaluation after a 6-week course of BCG and patients with Tis that persists after a second 6-week BCG course have a high likelihood of developing muscle-invasive disease and should be considered for cystectomy.[18,25,26]
TUR with fulguration followed by an immediate postoperative instillation of intravesical chemotherapy followed by intravesical chemotherapy
Intravesical therapy with thiotepa, MMC, doxorubicin, or BCG is most often used in patients with multiple tumors or recurrent tumors or as a prophylactic measure in high-risk patients after TUR.[27,28]
Evidence (intravesical chemotherapy):
Three meta-analyses of randomized controlled trials that compared TUR alone with TUR followed by intravesical chemotherapy reported that adjuvant therapy was associated with a statistically significant increase in time to recurrence. No advantage has been shown with respect to survival or prevention of progression to invasive disease or metastases.[29,30,31]
One analysis of eight studies with a combined total of 1,609 patients reported that intravesical chemotherapy reduced the risk of relapse at 1 year by 38% and by as much as 70% at 3 years, depending on which drugs were used.[30]
Another analysis of 11 studies that enrolled a total of 3,703 patients reported a 44% reduction in 1-year recurrence rates.[30]
An earlier study of 2,535 patients enrolled in six different randomized controlled trials reported a decreased risk of recurrence but not significant benefit with regard to risk of progression to more-advanced–stage disease or survival.[29]
Segmental cystectomy (rarely indicated)
Segmental cystectomy is rarely indicated.[32] It is indicated for relatively few patients because of the tendency of bladder carcinoma to involve multiple regions of the bladder mucosa and to occur in areas that cannot be segmentally resected. Moreover, cystectomy (whether segmental or radical) is generally not indicated for patients with T0 bladder cancer.[33,34]
Radical cystectomy in selected patients with extensive or refractory superficial tumors
Radical cystectomy is used in selected patients with extensive or refractory superficial tumors.[35,36,37,38,39,40,41,42,43] Patients at high risk of progression, typically those with recurrent high-grade tumors with carcinoma in situ after intravesical therapy with BCG, should consider radical cystectomy. Other risk factors include multiple tumors and tumors larger than 3 cm.
Certain patients with nonmuscle-invasive bladder cancer face a substantial risk of progression and death from their cancers.
Evidence (radical cystectomy):
One analysis of 307 patients enrolled in studies of intravesical BCG in the 1980s reported that among 85 patients with T1 recurrence, 60 progressed to at least stage II disease. Five years after T1 recurrence, 71% had progressed and 48% had died of their cancer.[44]
By comparison, in another cohort of 589 patients treated with BCG between 1992 and 2004, 65 of the 120 patients with T1 recurrence underwent immediate cystectomy. Among all patients with T1 recurrence, 28% progressed to more-advanced–stage disease and 31% died of their cancer. While these data confirm that patients with recurring cancer after intravesical BCG face a substantial risk of dying of their disease, they do not provide strong evidence that immediate cystectomy results in a lower risk of death or progression.[44]

Treatment of Stages II and III Bladder Cancer
Treatment Options for Stages II and III Bladder Cancer
Treatment options for stage II bladder cancer and stage III bladder cancer include the following:
Radical cystectomy.
Neoadjuvant combination chemotherapy followed by radical cystectomy.
Radical cystectomy followed by adjuvant chemotherapy or immunotherapy.
External-beam radiation therapy (EBRT) with or without concomitant chemotherapy.
Segmental cystectomy (in selected patients).
Transurethral resection (TUR) with fulguration (in selected patients).
The most common treatments for muscle-invasive bladder cancer are radical cystectomy and radiation therapy. There is no strong evidence from randomized controlled trials to determine whether surgery or radiation therapy is more effective. There is strong evidence that both therapies become more effective when combined with chemotherapy. The treatments with the highest level of evidence supporting their effectiveness are radical cystectomy preceded by multiagent cisplatin-based chemotherapy and radiation therapy with concomitant chemotherapy.
Radical cystectomy
Radical cystectomy is a standard treatment option for stage II and stage III bladder cancer, and its effectiveness at prolonging survival increases if it is preceded by cisplatin-based multiagent chemotherapy.[1,2,3,4] Radical cystectomy is accompanied by pelvic lymph node dissection and includes removal of the bladder, perivesical tissues, prostate, and seminal vesicles in men and removal of the uterus, fallopian tubes, ovaries, anterior vaginal wall, and urethra in women.[5,6,7,8] Studies of outcomes after radical cystectomy report increased survival in patients who had more, rather than fewer, lymph nodes resected; whether this represents a therapeutic benefit of resecting additional nodes or stage migration is unknown.[9] There are no randomized controlled trials evaluating the therapeutic benefit of lymph node dissection in this setting.
Radical cystectomy is a major operation with a perioperative mortality rate of 2% to 3% when performed at centers of excellence.[6,7,8] Postoperative complications include ileus. Most men have erectile dysfunction after radical cystectomy; sexual dysfunction after this operation is also common in women.[10,11,12]
One study of 27 women who underwent radical cystectomy reported diminished ability to have orgasm in 45%, decreased lubrication in 41%, decreased sexual desire in 37%, and pain with vaginal intercourse in 22%. Fewer than one-half were able to have successful vaginal intercourse and most reported decreased satisfaction with their sexual lives after surgery.[12] Studies suggest that radical cystectomy with preservation of sexual function can be performed in some men. In addition, new forms of urinary diversion can obviate the need for an external urinary appliance.[13,14,15,16]
In a retrospective analysis from a single institution, older patients (≥70 years) in good general health were found to have clinical and functional results after radical cystectomy similar to younger patients.[17]
After radical cystectomy, however, an approximate 30% to 40% risk of recurrence still exists for patients with muscle-invasive disease, even at centers of excellence.[6,7,8] Five-year overall survival (OS) rates have been reported as 50% to 60%, but these rates vary by cancer stage.[4] The addition of preoperative radiation therapy to radical cystectomy did not result in any survival advantage when compared with radical cystectomy alone in a prospective randomized trial.[18]
Neoadjuvant combination chemotherapy followed by radical cystectomy
Because bladder cancer commonly recurs with distant metastases, systemic chemotherapy administered before or after cystectomy has been evaluated as a means of improving outcome. Administration of chemotherapy before cystectomy (i.e., neoadjuvant chemotherapy) may be preferable to postoperative treatment because tumor downstaging from chemotherapy may enhance resectability; occult metastatic disease may be treated as early as possible; and chemotherapy may be better tolerated. Currently, the body of evidence supporting preoperative chemotherapy is much stronger than the evidence supporting postoperative chemotherapy.
Evidence (neoadjuvant combination chemotherapy followed by radical cystectomy):
A controlled trial of preoperative chemotherapy conducted by the Medical Research Council and the European Organisation for Research and Treatment of Cancer randomly assigned 976 patients with locally advanced (T3 or T4a) or high-grade muscle-invasive (T2) bladder cancer to undergo either definitive treatment immediately or definitive treatment preceded by three cycles of neoadjuvant cisplatin, vinblastine, and methotrexate.[19,20] In this study, definitive treatment consisted of radical cystectomy (n = 428), radiation therapy (n = 403), or preoperative radiation therapy followed by radical cystectomy (n = 66).
At a median follow-up of 8.0 years for patients still alive, OS was significantly greater in the arm randomly assigned to receive neoadjuvant chemotherapy (hazard ratio [HR], 0.84; 95% confidence interval [CI], 0.72–0.99; P = .037). The survival benefit from neoadjuvant chemotherapy compared with definitive treatment alone conferred a 6% absolute increase in the likelihood of being alive at 3 years (56% vs. 50%), 5 years (49% vs. 43%), and 10 years (36% vs. 30%).[20][Level of evidence A1]
A randomized study conducted by the Southwest Oncology Group compared three cycles of neoadjuvant cisplatin, methotrexate, vinblastine, and doxorubicin administered before cystectomy with cystectomy alone in 317 patients with stage T2 to stage T4a bladder cancer.[21]
The study showed that the 5-year survival rate was 57% in the group that received neoadjuvant chemotherapy and 43% in the group treated with cystectomy alone, which is a difference of borderline statistical significance (two-sided P value = .06 by stratified log-rank test).
No deaths were associated with neoadjuvant chemotherapy, and there was no difference in the rate or severity of postoperative complications in patients who received immediate surgery and in those who received preoperative chemotherapy. Cystectomy was performed as planned for 82% of patients assigned to preoperative chemotherapy and 81% of those assigned to cystectomy alone. This study provided evidence that preoperative chemotherapy does not prevent patients from undergoing cystectomy and does not increase the risk of perioperative complications.
Thirty-eight percent of patients who received neoadjuvant chemotherapy had a pathological complete response at the time of surgery, and 85% of those achieving a pathological complete response were alive at 5 years.
A meta-analysis of ten randomized trials of neoadjuvant chemotherapy, including updated data for 2,688 individual patients, showed that cisplatin-based combination chemotherapy was associated with a significant 13% relative reduction in the risk of death and resulted in an improvement in 5-year survival rates from 45% to 50% (P = .016). Neoadjuvant single-agent cisplatin was not associated with any survival benefit in the meta-analysis.[2]
A subsequent meta-analysis evaluated a nearly identical body of data (11 randomized controlled trials enrolling a total of 2,605 patients) and reached similar conclusions. When the analysis was limited to the eight trials that used multiagent, cisplatin-based chemotherapy, neoadjuvant chemotherapy compared with cystectomy alone was associated with a 6.5% absolute benefit in the 5-year OS rate (56.5% vs. 50%; P = .006).[4]
Most patients included in these studies received cisplatin, methotrexate, and vinblastine with or without doxorubicin. It is not known whether the doublet regimen of cisplatin plus gemcitabine offers any benefit when administered in the preoperative setting, nor is there any evidence of benefit for carboplatin-based chemotherapy regimens.
On the basis of these findings, preoperative cisplatin-based combination chemotherapy followed by radical cystectomy represents a standard therapeutic option for patients with muscle-invasive bladder cancer who are fit for chemotherapy and for whom the priority is to maximize survival.
Radical cystectomy followed by adjuvant chemotherapy or immunotherapy
Adjuvant chemotherapy
Numerous trials have investigated whether giving chemotherapy after radical cystectomy can improve progression-free survival (PFS) and OS. Although several trials showed a PFS benefit from postoperative cisplatin-based chemotherapy, the trials tended to be small and underpowered, and no trial demonstrated a persuasive benefit in OS.
Evidence (adjuvant chemotherapy):
A systematic review and meta-analysis evaluated nine randomized controlled trials that enrolled 945 patients. A variety of different cisplatin-based chemotherapy regimens were used.[22][Level of evidence A2]
This analysis reported a significant OS benefit for patients who received adjuvant chemotherapy (HR, 0.77; 95% CI, 0.49–0.99).
The disease-free survival (DFS) benefit was similar (HR, 0.66; 95% CI, 0.45–0.91).
Adjuvant immunotherapy
Evidence (adjuvant immunotherapy):
A randomized controlled trial compared nivolumab with placebo in 709 patients with pathological T3, T4, or node-positive muscle-invasive urothelial carcinoma who had undergone radical cystectomy. Of note, the patients in this trial had either received preoperative cisplatin-based chemotherapy, refused postoperative cisplatin-based chemotherapy, or been deemed unfit for cisplatin-based chemotherapy.[23][Level of evidence B1]
When analyzed at a median follow-up of 20 months, there was no difference in OS.
A significant difference in DFS (the primary end point) was reported for patients with high programmed death-ligand 1 (PD-L1) expression. The median DFS was 20.8 months (95% CI, 16.5–27.6) in the nivolumab arm and 10.8 months (95% CI, 8.3–13.9) in the placebo arm. The 6-month DFS rate was 74.9% for patients who received nivolumab and 60.3% for patients who received placebo (HR, 0.70; 98% CI, 0.55–0.90). However, there was no significant benefit for patients with low (<1%) PD-L1 expression.
Grade 3 or higher adverse events were seen in 42.7% of patients in the nivolumab arm and 36.8% of patients in the placebo arm. High-grade treatment-related adverse events were seen in 17.9% of patients in the nivolumab arm and 7.2% of patients in the placebo arm. The most common adverse events were pruritus, fatigue, and diarrhea, while the most common high-grade adverse events were elevated lipase or amylase, diarrhea, colitis, and pneumonitis. Two patients in the nivolumab arm died of pneumonitis, and one patient died of a bowel perforation.
Data for OS (the secondary end point) are immature.
EBRT with or without concomitant chemotherapy
Definitive radiation therapy is a standard option that yields 5-year survival rates of approximately 30% to 40%.[24] When radiation therapy and chemotherapy are administered concomitantly, the results are better. However, while the addition of chemotherapy to radiation therapy has been shown to reduce local relapse rates, it has not been shown to result in increased survival, decreased mortality, or improved quality of life.
Most protocols for bladder preservation that use combined chemotherapy and radiation therapy have followed a relatively complex algorithm. After the initial stage TUR of the bladder tumor, patients undergo a repeat TUR to maximally resect the tumor. The patient is then treated with synchronous chemoradiation therapy to a dose of roughly 40 Gy followed by a repeat cystoscopy with biopsies to assess for residual cancer. If residual cancer is detected histopathologically, then the chemoradiation therapy is judged to have failed and the patient is advised to undergo a radical cystectomy. If the biopsies at 40 Gy are benign, then chemoradiation therapy is completed to a dose of about 65 Gy.
With definitive radiation therapy, best results are seen in patients with solitary lesions and without carcinoma in situ or hydronephrosis.
After radiation therapy, approximately 50% of patients have dysuria and urinary frequency during treatment, which resolves several weeks after treatment, and 15% report acute toxic effects of the bowel.
Randomized trials that directly compare the bladder-preserving chemoradiation therapy approach with radical cystectomy have not been performed; the relative effectiveness of these two treatments is thus unknown.
Evidence (EBRT with or without concomitant chemotherapy):
TUR followed by chemoradiation therapy
A multicenter phase III trial randomly assigned 360 patients with muscle-invasive bladder cancer to radiation therapy with or without synchronous chemotherapy using fluorouracil and mitomycin.[24]
The 2-year locoregional DFS rate was higher in the chemoradiation therapy group (67% vs. 54%; HR, 0.68; 95% CI, 0.48–0.96; P = .03). The 5-year OS rate was 48% in the chemoradiation therapy group and 35% in the radiation therapy group, but the difference was not statistically significant (P = .16).
Similarly, synchronous chemoradiation therapy using other chemotherapy regimens, such as cisplatin alone or combined with fluorouracil, have reported 5-year OS rates of 50% to 60% and survival with an intact bladder in 40% to 45% of patients, figures that are higher than has generally been reported in studies of radiation therapy alone.[25]
TUR followed by chemoradiation therapy
In some nonrandomized studies, 50% or more of the patients who underwent bladder-preserving therapy (i.e., initial TUR of as much tumor as possible followed by concurrent chemoradiation therapy) were alive at 5 years, and 75% of those survivors had an intact bladder.[26,27,28]
Radiation therapy and chemotherapy
A randomized controlled trial randomly assigned 99 patients with T2 to T4b urothelial carcinoma of the bladder to radiation therapy with or without three 14-day cycles of cisplatin (100 mg/m2 on day 1). Patients and their physicians chose whether the radiation therapy was definitive or administered as precystectomy treatment. The pelvic relapse rate was reduced (multivariable regression model HR, 0.50; 90% CI, 0.29–0.86; P = .036), but there was no difference in the occurrence of distant metastases or OS. The reduction in pelvic relapse was similar in patients who received definitive radiation therapy and precystectomy radiation therapy.[29]
Neoadjuvant chemotherapy followed by chemoradiation therapy
In a phase III study (RTOG-8903), the Radiation Therapy Oncology Group evaluated the potential benefit of adding two cycles of neoadjuvant methotrexate, cisplatin, and vinblastine before concurrent cisplatin and radiation therapy. Neoadjuvant chemotherapy was associated with increased hematologic toxic effects and yielded no improvement in response rate, freedom from distant metastases, or OS compared with chemoradiation therapy alone.[30]
Segmental cystectomy (in selected patients)
Segmental cystectomy is appropriate only in very selected patients.[1] There are no randomized controlled trials comparing segmental cystectomy with radical cystectomy. Only patients with adenocarcinomas of the urachus are routinely treated with segmental cystectomy. These tumors typically are mucinous adenocarcinomas occurring at the dome of the bladder and are treated with an en bloc resection of the bladder dome and urachal remnant, including the umbilicus.[31,32,33,34]
TUR with fulguration (in selected patients)
Stage II bladder cancer may be controlled in some patients by TUR, but more aggressive forms of treatment are often dictated by recurrent tumor or by the large size, multiple foci, or undifferentiated grade of the neoplasm.

Treatment of Stage IV Bladder Cancer
Few patients with stage IV bladder cancer can be cured, and for many patients, the emphasis is on palliation of symptoms. The potential for cure is restricted to patients with stage IV disease with involvement of pelvic organs by direct extension or metastases to regional lymph nodes.[1]
Treatment Options for Stage IV Bladder Cancer
Treatment options for patients with T4b, N0, M0 disease
Treatment options for patients with T4b, N0, M0 disease include the following:
Enfortumab vedotin plus pembrolizumab.
Chemotherapy plus immunotherapy.
Chemotherapy alone.
Systemic therapy followed by radical cystectomy.
External-beam radiation therapy (EBRT) with or without concomitant chemotherapy.
Urinary diversion or cystectomy for palliation.
Enfortumab vedotin plus pembrolizumab
Enfortumab vedotin is an antibody-drug conjugate, combining an antibody that binds to nectin-4 with a microtubule inhibitor. The U.S. Food and Drug Administration (FDA) approved enfortumab vedotin as monotherapy for patients with previously treated metastatic urothelial carcinoma. Pembrolizumab is an anti−programmed death-1 (PD-1) antibody that the FDA has approved as monotherapy for patients with metastatic bladder cancer. The combination of the two agents showed a promising response rate and duration of response, leading to a single-arm phase II trial and then a comparison with chemotherapy in a randomized, controlled, phase III trial.[2,3,4] While results cannot be extrapolated across trials, enfortumab vedotin plus pembrolizumab is a first-line therapy option for patients without a contraindication.
Evidence (enfortumab vedotin plus pembrolizumab):
In a phase III trial (NCT04223856), published in abstract form, 886 patients were randomly assigned to receive either enfortumab vedotin plus pembrolizumab (n = 442) or gemcitabine plus either cisplatin or carboplatin (n = 444). The median follow-up was 17 months.[4][Level of evidence A1]
Overall survival (OS) and progression-free survival (PFS) were longer for patients in the enfortumab vedotin-plus-pembrolizumab arm than in the chemotherapy arm.
The median OS was 31.5 months for patients who received enfortumab vedotin plus pembrolizumab and 16.1 months for patients who received chemotherapy (hazard ratio [HR], 0.47; 95% confidence interval [CI], 0.38–0.58; P < .00001).
PFS was 12.5 months for patients who received enfortumab vedotin plus pembrolizumab and 6.3 months for patients who received chemotherapy (HR, 0.45; 95% CI, 0.38–0.54).
Grade 3 or higher adverse events occurred in 55.9% of patients who received enfortumab vedotin plus pembrolizumab and 69.5% of patients who received chemotherapy.
In the experimental arm, the most common high-grade adverse events were skin reactions, peripheral neuropathy, hyperglycemia, and neutropenia.
Chemotherapy plus immunotherapy
For many years, cisplatin-based chemotherapy was the standard-of-care first-line systemic treatment for patients with stage IV urothelial carcinoma who were eligible to receive cisplatin. A randomized, controlled, phase III trial reported longer OS when cisplatin-based chemotherapy was given with nivolumab, compared with chemotherapy alone.[5]
Evidence (chemotherapy plus immunotherapy):
A randomized, controlled, phase III trial (CheckMate901 [NCT03036098]) randomly assigned 608 patients (304 to each arm) to receive either nivolumab plus gemcitabine and cisplatin or gemcitabine and cisplatin alone. Patients received up to six cycles of chemotherapy and up to 2 years of nivolumab. The median follow-up was 33.6 months.[5]
The median OS was 21.7 months for patients who received nivolumab and 18.9 months for patients who received chemotherapy alone (HRdeath, 0.78; 95% CI, 0.63–0.96, P = .02).[5][Level of evidence A1]
The median PFS was 7.9 months for patients who received nivolumab and 7.6 months for patients who received chemotherapy alone (HRprogression or death, 0.72; 95% CI, 0.59–0.88; P = .001).
At 1 year, the PFS rate was 34.2% in the nivolumab arm and 21.8% in the chemotherapy-alone arm.
The overall response rate was 57.6% in the nivolumab arm and 21.7% in the chemotherapy-alone arm. The complete response rate was 21.7% in the nivolumab arm and 11.8% in the chemotherapy-alone arm.
The duration of complete response was 37.1 months in the nivolumab arm and 13.2 months in the chemotherapy-alone arm.
Grade 3 or higher adverse events occurred in 61.8% of patients in the nivolumab arm and 51.7% of patients in the chemotherapy-alone arm.
Chemotherapy alone
Cisplatin-based combination chemotherapy regimens are a standard of care option for patients with stage IV bladder cancer.[6,7,8,9,10] The only chemotherapy regimens that have been shown to result in longer survival in randomized controlled trials are methotrexate, vinblastine, doxorubicin, and cisplatin (MVAC); high-dose MVAC; and cisplatin, methotrexate, and vinblastine (CMV). Gemcitabine plus cisplatin (GC) was compared with MVAC in a randomized controlled trial and no difference in response rate or survival was reported. Of note, patients with good performance status and lymph node-only disease have a low but significant rate of achieving a durable complete remission with MVAC or GC. For example, in the large, randomized controlled trial that compared MVAC with GC, the 5-year overall survival (OS) rate in patients with lymph node-only disease was 20.9%.[11]
Single-agent cisplatin and multiagent regimens that do not include cisplatin have never shown improved survival in a randomized controlled trial. For patients who are not candidates for cisplatin-based multiagent chemotherapy regimens, there is no regimen that has been shown to prolong survival; however, many regimens have demonstrated radiologically measurable responses.
These include carboplatin plus paclitaxel,[12] carboplatin plus gemcitabine,[13,14,15] paclitaxel plus gemcitabine,[16,17,18] single-agent gemcitabine,[19,20] and single-agent paclitaxel.[21,22,23] Regimens of carboplatin, methotrexate, and vinblastine; carboplatin, epirubicin, methotrexate, and vinblastine; and paclitaxel, gemcitabine, and carboplatin have been studied but are not widely used.[24,25,26,27]
Evidence (chemotherapy alone):
Results from a randomized controlled trial that compared MVAC with docetaxel plus cisplatin in 220 patients reported that MVAC was associated with longer OS (median survival, 14.2 months vs. 9.3 months; P = .026).[28]
A randomized trial that compared MVAC with cisplatin, cyclophosphamide, and doxorubicin demonstrated improved response and median survival rates (48 weeks vs. 36 weeks; P = .003) with the MVAC regimen.[29]
Results from a randomized trial that compared MVAC with single-agent cisplatin in advanced bladder cancer also showed a significant advantage with MVAC in both response rate and median survival (12.5 months vs. 8.2 months; P = .002).[30]
A multicenter randomized controlled trial compared CMV with methotrexate plus vinblastine without cisplatin in 214 patients. The relative risk of dying was 0.68 (95% confidence interval [CI], 0.51–0.90; P = .0065) in favor of CMV. The median survival was 7 months with CMV and 4.5 months with methotrexate plus vinblastine.[31]
The European Organisation for Research and Treatment of Cancer (EORTC) conducted another randomized trial that studied 263 patients with advanced bladder cancer and evaluated the efficacy of a high-dose intensity MVAC regimen administered every 2 weeks with granulocyte colony-stimulating factor (G-CSF) versus a classic MVAC regimen administered every 4 weeks.[32]
Although there was no significant difference in OS at a median follow-up of 3.2 years (hazard ratio [HR], 0.80; 95% CI, 0.60–1.06; P = .122), an update at a median follow-up of 7.3 years reported that the high-dose intensity MVAC regimen was associated with improved OS (HR, 0.76; 95% CI, 0.58–0.99; P = .042), with a 5-year survival rate of 22% compared with 14% in patients treated with the classic MVAC regimen.
The high-dose intensity MVAC regimen was also associated with higher response rates (72% vs. 58%; P = .016), improved median progression-free survival (PFS) (9.5 months vs. 8.1 months; P = .017), and decreased neutropenic fever (10% vs. 26%; P < .001), although only 19% of patients treated with a classic MVAC regimen ever received G-CSF.[32][Level of evidence A1] An imbalance in baseline prognostic factors (i.e., visceral metastases were found in 37 patients randomly assigned to the high-dose MVAC regimen and 47 patients assigned to the classic MVAC regimen) may account, in part, for these results.
Gemcitabine plus cisplatin.
In a multicenter, randomized, phase III trial that compared GC with the MVAC regimen in 405 patients with advanced or metastatic bladder cancer, GC yielded response rates, time-to-progression, and OS (HR, 1.04; 95% CI, 0.82–1.32; P = .75) similar to MVAC, but GC had a better safety profile and was better tolerated than MVAC.
Although this study was not designed to show the equivalence of the two regimens, the similar efficacy and reduced toxic effects of GC make it a reasonable alternative in patients who may not tolerate the MVAC regimen.[33][Level of evidence A1]
External-beam radiation therapy (EBRT) with or without concomitant chemotherapy
Definitive radiation therapy with or without concurrent chemotherapy, evaluated mainly in patients with locally advanced (T2–T4) disease, appears to have minimal curative potential in patients with regional lymph node metastases.[34,35] Patients with evidence of lymph node metastases have generally been excluded from phase III trials of radiation therapy.[36,37]
Urinary diversion or cystectomy for palliation
Urinary diversion may be indicated, not only for palliation of urinary symptoms but also for preservation of renal function in candidates for chemotherapy.
Treatment options for patients with any T, any N, M1 disease
Treatment options for patients with any T, any N, M1 disease include the following:
Enfortumab vedotin plus pembrolizumab.
Chemotherapy plus immunotherapy.
Chemotherapy alone or as an adjunct to local treatment.
Immunotherapy.
EBRT for palliation.
Urinary diversion or cystectomy for palliation.
Other chemotherapy agents with activity in metastatic bladder cancer, such as paclitaxel, docetaxel, and ifosfamide (under clinical evaluation).[38,39][Level of evidence C3]
Clinical trials.
Enfortumab vedotin plus pembrolizumab
Enfortumab vedotin is an antibody-drug conjugate, combining an antibody that binds to nectin-4 with a microtubule inhibitor. The FDA approved enfortumab vedotin as monotherapy for patients with previously treated metastatic urothelial carcinoma.

OS and PFS were longer for patients in the enfortumab vedotin-plus-pembrolizumab arm than in the chemotherapy arm.

Grade 3 or higher adverse events occurred in 61.8% of patients in the nivolumab arm and 51.7% of patients in the chemotherapy-alone arm.
Chemotherapy alone or as an adjunct to local treatment
Cisplatin-based combination chemotherapy regimens are the standard of care for first-line therapy for stage IV bladder cancer in patients who can tolerate it.[6,7,8,9,10] The only chemotherapy regimens that have been shown to result in longer survival in randomized controlled trials are MVAC, dose-dense MVAC, and CMV. GC was compared with MVAC in a randomized controlled trial and neither regimen was associated with a statistically significant difference in response rate or survival. The two regimens are generally considered equivalent, but they have never been compared in a noninferiority trial. Of note, patients with good performance status and lymph node-only disease have a low but significant rate of achieving a durable complete remission with MVAC or GC. In the large, randomized controlled trial comparing MVAC with GC, for example, the 5-year OS rate in patients with lymph node-only disease was 20.9%.[11] Dose-dense MVAC and standard-dose MVAC were compared in a randomized controlled trial, and dose-dense MVAC was associated with longer survival.
Single-agent cisplatin and multiagent regimens that do not include cisplatin have never been shown to improve survival in a randomized controlled trial. For patients who are not candidates for cisplatin-based multiagent chemotherapy regimens, there is no regimen that has been shown to prolong survival; however, many regimens have demonstrated radiologically measurable responses.
These include carboplatin plus paclitaxel,[12] carboplatin plus gemcitabine,[13,14,15] paclitaxel plus gemcitabine,[16,17,18] single-agent gemcitabine,[19,20] and single-agent paclitaxel.[21,22,23] The regimens of carboplatin, methotrexate, and vinblastine; carboplatin, epirubicin, methotrexate, and vinblastine; and paclitaxel, gemcitabine, and carboplatin have been studied but are not widely used.[24,25,26,27]
Ongoing studies are evaluating new chemotherapy combinations.
Evidence (chemotherapy):
A prospective randomized trial that compared MVAC with cisplatin, cyclophosphamide, and doxorubicin demonstrated improved response rate and longer median survival (48 weeks vs. 36 weeks; P = .003) with the MVAC regimen.[29]
Results from a randomized trial that compared MVAC with single-agent cisplatin in advanced bladder cancer also showed a significant advantage with MVAC in both response rate and median survival (12.5 months vs. 8.2 months; P = .002).[30]

Although this study was not designed to show the equivalence of the two regimens, the similar efficacy and reduced toxic effects of GC make it a reasonable alternative in patients who may not tolerate the MVAC regimen.[33][Level of evidence A1]
Other chemotherapy regimens that have shown activity in metastatic bladder cancer include single-agent paclitaxel, single-agent gemcitabine, single-agent pemetrexed, carboplatin combined with either gemcitabine or paclitaxel, and gemcitabine combined with paclitaxel. There are no phase III trials demonstrating a survival or quality-of-life benefit from second-line chemotherapy.[13,16,18,19,27,40,41,42,43,44,45,46,47,48,49,50,51,52]
Ongoing studies are evaluating new chemotherapy combinations.
Immunotherapy
Immunotherapy has emerged as a treatment alternative for patients with stage IV bladder cancer. Immune checkpoint inhibitors that have anti−PD-1 or anti−programmed death-ligand 1 (PD-L1) activity have been shown in clinical trials to have activity against urothelial carcinoma in patients who have previously been treated with or who are ineligible for platinum-based chemotherapy.[53,54,55,56,57] There are currently several different agents approved; however, pembrolizumab is the agent with the highest level of evidence and the greatest data in terms of survival.
Pembrolizumab
Pembrolizumab is a humanized monoclonal antibody that binds to PD-1. In patients previously treated with platinum-based chemotherapy, pembrolizumab has been shown to prolong OS compared with second-line chemotherapy. As a result, pembrolizumab has been approved by the FDA for patients with locally advanced or metastatic urothelial carcinoma who fall into one of the following three categories:
Cisplatin-ineligible and have tumors that express PD-L1 (combined positive score [CPS] of at least 10%).
Cisplatin- and carboplatin-ineligible.
Progression of disease after treatment with platinum-based chemotherapy.
It is important to note that in 2018, the FDA issued an alert about preliminary data from two ongoing first-line therapy trials comparing pembrolizumab or atezolizumab with cisplatin- or carboplatin-based therapy. The data showed that immunotherapy was associated with shorter survival in patients with low expression of PD-L1. As a result, the labels were amended to restrict use of both agents to the three categories above.
Evidence (pembrolizumab):
In an open-label, international, randomized controlled, phase III trial (NCT02256436) of pembrolizumab (200 mg intravenously [IV] every 21 days) versus second-line chemotherapy (investigator's choice of paclitaxel, docetaxel, or vinflunine) in patients whose disease had progressed after treatment with platinum-based chemotherapy, median OS was longer with pembrolizumab (10.3 months vs. 7.4 months; HR, 0.73; 95% CI, 0.59–0.91).[58]
In patients with a PD-L1 CPS of at least 10%, the median OS was 8.0 months with pembrolizumab compared with 5.2 months of chemotherapy (HR, 0.57; 95% CI, 0.37–0.88).
The PFS rate at 12 months was 16.8% (95% CI, 12.3%–22.0%) in the pembrolizumab arm and 6.2% (95% CI, 3.3%–10.2%) in the chemotherapy arm.
The objective response rate was 21.1% in the pembrolizumab arm and 11.4% in the chemotherapy arm. Among those who responded, the median duration of response was longer than 18 months with pembrolizumab compared with a response of 4.3 months with chemotherapy.
Pembrolizumab was associated with a lower rate of treatment-related adverse events than was chemotherapy (60.9% vs. 90.2%) and a lower rate of high-grade adverse events (15.0% vs. 49.4%). The most common adverse events with pembrolizumab were pruritus, fatigue, nausea, diarrhea, and decreased appetite.[58][Level of evidence A1]
In a single-arm, phase II trial (NCT02335424) of pembrolizumab in 370 treatment-naïve, cisplatin-ineligible patients with locally advanced or metastatic urothelial carcinoma, the overall response rate was 29%. In patients with a PD-L1 CPS of at least 10%, the overall response rate was 51%.[59]
The median duration of response had not been reached. Eighty-two percent of responses lasted at least 6 months.
Ten percent of patients had a serious treatment-related adverse event, and one patient died of treatment-related adverse events. The most common high-grade adverse events were fatigue (2%), elevated alkaline phosphatase (1%), colitis (1%), and muscle weakness (1%).[59][Level of evidence C3]
Atezolizumab
Atezolizumab is a humanized monoclonal antibody that binds to PD-L1 and prevents it from binding to its receptors, PD-1 or B7-1. Clinical trials have reported that atezolizumab acts against urothelial carcinoma, but it has not shown prolonged OS or improved quality of life. The only randomized controlled trial testing atezolizumab reported no significant difference in OS compared with second-line chemotherapy.
The FDA approved atezolizumab for patients with locally advanced or metastatic urothelial carcinoma who fall into one of the following three categories:
Cisplatin-ineligible and have tumors that express PD-L1 (at least 5% of the tumor area covered by tumor-infiltrating immune cells that stain for PD-L1).
Cisplatin- and carboplatin-ineligible.
Progression of disease after treatment with platinum-based chemotherapy.
It is important to note that in 2018, the FDA issued an alert about preliminary data from two ongoing first-line therapy trials comparing pembrolizumab or atezolizumab with cisplatin- or carboplatin-based therapy. The data showed that immunotherapy was associated with shorter survival in patients with low expression of PD-L1. As a result, the labels were amended to restrict use of both agents to the three categories above.
Evidence (atezolizumab):
The IMvigor211 trial (NCT02302807) is a randomized, controlled trial that compared atezolizumab with second-line chemotherapy (docetaxel, paclitaxel, or vinflunine) in 931 patients with locally advanced or metastatic urothelial carcinoma who were previously treated with platinum-containing chemotherapy.[60] The trial design specified that OS would be primarily assessed in patients with tumors in which at least 5% of cells stained for PD-L1.
The median OS was 11.1 months for atezolizumab versus 10.6 months for chemotherapy in patients with at least 5% of tumor cells staining for PD-L1 (P = .41).[60][Level of evidence A1]
Response rates were also similar: 23% with atezolizumab and 22% with chemotherapy.
Patients receiving atezolizumab had a lower rate of high-grade toxicity (20% vs. 43%) and a lower rate of treatment discontinuation resulting from adverse events (7% vs. 18%).
A multicenter single-arm trial (NCT0108652) included 315 cisplatin-ineligible patients or patients who were previously treated with platinum-based chemotherapy and who had inoperable locally advanced or metastatic urothelial carcinoma. Patients received atezolizumab (1,200 mg IV every 21 days). The following results were reported:[56][Level of evidence C2]
The overall response rate was 15%.
With a median follow-up of 11.7 months, 38 of 45 responders (84%) had an ongoing response.
The response rate was 27% in those with PD-L1 expression of at least 5%, 10% in those with PD-L1 expression of 1% to 5%, and 8% in those with PD-L1 expression of less than 1%.
Grade 3 to 4 adverse events were reported in 16% of patients, and high-grade, immune-related adverse events were reported in 5% of patients.
Similarly, a study (NCT02108652) of 123 previously untreated patients with cisplatin-ineligible, locally advanced metastatic urothelial carcinoma who were treated with atezolizumab reported that at a median follow-up of 17.2 months, the objective response rate was 23%, and 9% had complete responses.[57][Level of evidence C2]
Of the 27 responses, 19 were ongoing at the time of data analysis. Median OS was 15.9 months.
High-grade adverse events were reported in 16% of patients, 8% of patients discontinued treatment because of the adverse events, and there was one treatment-related death.
Nivolumab
Nivolumab is a fully human immunoglobulin G4 PD-1 immune checkpoint inhibitor antibody that blocks interaction between PD-L1 and PD-L2 with PD-1. There are no published controlled trials and thus no data regarding whether nivolumab results in longer survival or improved quality of life.
Evidence (nivolumab):
A multicenter trial (NCT01928394) included 86 patients with metastatic urothelial carcinoma whose disease progressed after platinum-based chemotherapy. Patients received nivolumab (3 mg/kg IV every 2 weeks).[55][Level of evidence B4]
With a minimum follow-up of 9 months and a median follow-up of 15 months, 24% of patients had an objective response, and 22% had grade 3 or 4 adverse events.
The most common adverse events were elevated lipase or amylase, fatigue, rash, dyspnea, lymphopenia, and neutropenia.
Another multicenter study (NCT02387996) of 270 patients with locally advanced or metastatic urothelial carcinoma that had progressed after treatment with platinum-based chemotherapy reported an objective response rate of 20%.[54][Level of evidence B4]
When evaluated by PD-L1 expression, the objective response rate was 28% in those with PD-L1 expression of 5% or greater; 24% in those with PD-L1 expression of 1% or greater; and 16% in those with PD-L1 expression of less than 1%.
Grade 3 to 4 adverse events were reported in 18% of patients.
There were three treatment-related deaths.
Avelumab
Avelumab is a monoclonal anti–PD-L1 antibody that has shown activity against urothelial carcinoma. A randomized controlled trial reported an OS benefit from maintenance avelumab when given after platinum-based chemotherapy in patients whose cancer did not progress during chemotherapy.
Evidence (avelumab):
A phase III study (NCT02603432) evaluated maintenance avelumab (10 mg/kg IV every 14 days) in patients with metastatic urothelial carcinoma who had not progressed during treatment with first-line chemotherapy with gemcitabine combined with either cisplatin or carboplatin. After four to six cycles of chemotherapy, 700 patients were randomly assigned to receive either best supportive care (control arm) or best supportive care plus maintenance avelumab (avelumab arm).[61][Level of evidence A1]
The 1-year OS rate was 71.3% in the avelumab arm compared with 58.4% in the control arm (HR, 0.69; 95% CI, 0.56–0.86).
The OS benefit was limited to patients whose tumors were PD-L1 positive. The OS in patients with PD-L1–negative tumors was not significantly different between the two arms.
Patients with PD-L1–positive tumors had a 1-year OS rate of 79.1% in the avelumab arm and 60.4% in the control arm (HR, 0.56; 95% CI, 0.40–0.79).
In the overall study population, the median PFS was 3.7 months for patients in the avelumab arm and 2.0 months for patients in the control arm (HR, 0.62; 95% CI, 0.52–0.75). In patients with PD-L1–positive tumors, the median PFS was 5.7 months with avelumab and 2.1 months with best supportive care alone (HR, 0.56; 95% CI, 0.43–0.73).
Grade 3 or higher adverse events were reported for 47.4% of patients in the avelumab arm and 25.2% of patients in the control arm. Most adverse events with avelumab were immune related, and 9% of patients who received avelumab were treated with high-dose glucocorticoids for these events.
A study (NCT01772004) of avelumab (10 mg/kg IV every 14 days) in 249 patients with metastatic urothelial carcinoma who had progressed after treatment with platinum-based chemotherapy reported the following results:[62,63][Level of evidence C3]
Among the 161 patients with at least 6 months of follow-up, the overall response rate was 17%, and response was ongoing in 23 of 28 responders with a median follow-up of 7.3 months. Six percent of the patients had a complete response.
The overall response rate was 25.0% in patients with at least 5% of tumor cells staining for PD-L1 and 14.7% for those with less than 5% PD-L1 positivity.
Median PFS was 6.3 weeks; 23% of the patients were progression free at 24 weeks.
A treatment-related adverse event was reported in 66.7% of patients, including 8.4% of patients with high-grade adverse events. There was one treatment-related death from pneumonitis. High-grade immune-related adverse events were reported in 2.4% of patients.
Durvalumab
Durvalumab is an anti–PD-L1 monoclonal antibody that has shown activity against urothelial carcinoma. There are no published controlled trials and no data demonstrating either longer survival or improved quality of life with this agent.
Evidence (durvalumab):
The efficacy of durvalumab (10 mg/kg IV every 14 days) was assessed in a study (NCT01693562) of 191 patients with locally advanced or metastatic urothelial carcinoma whose disease had progressed while they were on chemotherapy or who were either ineligible for or unwilling to be treated with chemotherapy.[64][Level of evidence C3]
With a median follow-up of 5.78 months, the overall response rate was 17.8%.
The response rate was 27.6% in patients with high expression of PD-L1 compared with 5.1% in patients with low or no PD-L1 expression.
High-grade adverse events were reported in 6.8% of patients, including 2.1% with high-grade immune-mediated adverse events.
EBRT for palliation
Definitive radiation therapy with or without concurrent chemotherapy, evaluated mainly in patients with locally advanced (T2–T4) disease, appears to have minimal curative potential in patients with regional lymph node metastases.
Urinary diversion or cystectomy for palliation
Urinary diversion may be indicated, not only for palliation of urinary symptoms, but also for preservation of renal function in candidates for chemotherapy.

Treatment of Recurrent Bladder Cancer
The prognosis for any patient with progressive or recurrent invasive bladder cancer is generally poor. Management of recurrence depends on previous therapy, sites of recurrence, and individual patient considerations.
Treatment Options for Recurrent Bladder Cancer
Treatment options for patients with recurrent bladder cancer include the following:
Combination chemotherapy.
Immunotherapy.
Targeted therapy.
Surgery for new superficial or localized tumors.
Palliative therapy.
Clinical trials.
Combination chemotherapy
Patients who have not received previous chemotherapy for urothelial carcinoma should be considered for chemotherapy as described above for stage IV disease.
In patients with recurrent transitional cell carcinoma, combination chemotherapy has produced high response rates, with occasional complete responses seen.[1,2]
Cisplatin-based combination chemotherapy regimens are the standard of care for first-line therapy for stage IV bladder cancer in patients who can tolerate it.[3,4,5,6,7] The only chemotherapy regimens that have been shown to result in longer survival in randomized controlled trials are MVAC (methotrexate, vinblastine, doxorubicin, and cisplatin), dose-dense MVAC, and CMV (cisplatin, methotrexate, and vinblastine).
GC (gemcitabine and cisplatin) was compared with MVAC in a randomized controlled trial, and neither regimen was associated with a statistically significant difference in response rate or survival. The two regimens are generally considered equivalent, but they have never been compared in a noninferiority trial. Of note, patients with good performance status and lymph node–only disease have a low but significant rate of achieving a durable complete remission with MVAC or GC. In the large, randomized, controlled trial comparing MVAC with GC, for example, the 5-year overall survival (OS) rate in patients with lymph node–only disease was 20.9%.[8] Dose-dense MVAC and standard-dose MVAC were compared in a randomized controlled trial, and dose-dense MVAC was associated with longer survival.
Single-agent cisplatin and multiagent regimens that do not include cisplatin have never been shown to improve survival in a randomized controlled trial. For patients who are not candidates for cisplatin-based multiagent chemotherapy regimens, there is no regimen that has been shown to prolong survival; however, many regimens have demonstrated radiologically measurable responses.
These regimens include carboplatin plus paclitaxel,[9] carboplatin plus gemcitabine,[10,11,12] paclitaxel plus gemcitabine,[13,14,15] single-agent gemcitabine,[16,17] and single-agent paclitaxel.[18,19,20] The regimens of carboplatin, methotrexate, and vinblastine; carboplatin, epirubicin, methotrexate, and vinblastine; and paclitaxel, gemcitabine, and carboplatin have been studied but are not widely used.[21,22,23,24]
Evidence (combination chemotherapy):
In a prospective randomized trial that compared MVAC with cisplatin, cyclophosphamide, and doxorubicin, the MVAC regimen demonstrated improved response rate and longer median survival (48 weeks vs. 36 weeks; P = .003).[25]
Results from a randomized trial that compared MVAC with single-agent cisplatin in advanced bladder cancer also showed a significant advantage with MVAC in both response rate and median survival (12.5 months vs. 8.2 months; P = .002).[26]
A multicenter randomized controlled trial compared CMV with methotrexate plus vinblastine without cisplatin in 214 patients. The relative risk of dying was 0.68 (95% confidence interval [CI], 0.51–0.90; P = .0065) in favor of CMV. The median survival was 7 months with CMV compared with 4.5 months for methotrexate plus vinblastine.[27]
The European Organisation for Research and Treatment of Cancer (EORTC) conducted another randomized trial that studied 263 patients with advanced bladder cancer and evaluated the efficacy of a high-dose intensity MVAC regimen administered every 2 weeks with granulocyte colony-stimulating factor (G-CSF) versus a classic MVAC regimen administered every 4 weeks.[28]
Although there was no significant difference in OS at a median follow-up of 3.2 years (hazard ratio [HR], 0.80; 95% CI, 0.60–1.06; P = .122), an update at a median follow-up of 7.3 years reported that the high-dose intensity MVAC regimen was associated with improved OS (HR, 0.76; 95% CI, 0.58–0.99; P = .042), with a 5-year survival rate of 22% compared with 14% in patients treated with the classic MVAC regimen.
The high-dose intensity MVAC regimen was also associated with higher response rates (72% vs. 58%; P = .016), improved median progression-free survival (PFS) (9.5 months vs. 8.1 months; P = .017), and decreased neutropenic fever (10% vs. 26%; P < .001), although only 19% of patients treated with a classic MVAC regimen ever received G-CSF.[28][Level of evidence A1] An imbalance in baseline prognostic factors (i.e., visceral metastases were found in 37 patients randomly assigned to the high-dose MVAC regimen and 47 patients assigned to the classic MVAC regimen) may account, in part, for these results.
Gemcitabine plus cisplatin.
In a multicenter, randomized, phase III trial that compared GC with the MVAC regimen in 405 patients with advanced or metastatic bladder cancer, GC yielded response rates, time-to-progression, and OS (HR, 1.04; 95% CI, 0.82–1.32; P = .75) similar to MVAC, but GC had a better safety profile and was better tolerated than MVAC.
Although this study was not designed to show the equivalence of the two regimens, the similar efficacy and reduced toxic effects of GC make it a reasonable alternative in patients who may not tolerate the MVAC regimen.[29][Level of evidence A1]
Other chemotherapy regimens that have shown activity in metastatic bladder cancer include single-agent paclitaxel, single-agent gemcitabine, single-agent pemetrexed, carboplatin combined with either gemcitabine or paclitaxel, and gemcitabine combined with paclitaxel. There are no phase III trials demonstrating a survival or quality-of-life benefit from second-line chemotherapy.[30,31,32,33,34,35,36,37]
Immunotherapy
Immunotherapy has emerged as a treatment alternative for patients with recurrent bladder cancer. Immune checkpoint inhibitors that have anti−programmed death-1 (PD-1) or anti−programmed death-ligand 1 (PD-L1) activity have been shown in clinical trials to have activity against urothelial carcinoma in patients who have previously been treated with or who are ineligible for cisplatin-based chemotherapy.[38,39,40,41,42] There are currently four different agents approved; however, pembrolizumab is the agent with the highest level of evidence and the greatest data in terms of survival.
Pembrolizumab
Pembrolizumab is a humanized monoclonal antibody that binds to PD-1. In patients previously treated with platinum-based chemotherapy, pembrolizumab has been shown to prolong OS compared with second-line chemotherapy. As a result, the U.S. Food and Drug Administration (FDA) approved pembrolizumab for patients with locally advanced or metastatic urothelial carcinoma who fall into one of the following three categories:
Cisplatin-ineligible and have tumors that express PD-L1 (combined positive score [CPS] of at least 10%).
Cisplatin- and carboplatin-ineligible.
Progression of disease after treatment with platinum-based chemotherapy.
It is important to note that in 2018, the FDA issued an alert that preliminary data from two ongoing trials showed shorter survival in first-line therapy trials comparing pembrolizumab or atezolizumab with cisplatin- or carboplatin-based therapy. As a result, the labels were amended to restrict use of both agents to the three categories above.
Evidence (pembrolizumab):
In an open-label, international, randomized, controlled phase III trial (NCT02256436) of pembrolizumab (200 mg intravenously [IV] every 21 days) versus second-line chemotherapy (investigator's choice of paclitaxel, docetaxel, or vinflunine) in patients whose disease progressed after treatment with platinum-based chemotherapy, median OS was longer with pembrolizumab (10.3 months vs.7.4 months; HR, 0.73; 95% CI, 0.59–0.91).[43]
In patients with a PD-L1 CPS of at least 10%, median OS was 8.0 months with pembrolizumab compared with 5.2 months of chemotherapy (HR, 0.57; 95% CI, 0.37–0.88).
The PFS rate at 12 months was 16.8% (95% CI, 12.3%–22.0%) in the pembrolizumab arm and 6.2% (95% CI, 3.3%–10.2%) in the chemotherapy arm.
The objective response rate was 21.1% in the pembrolizumab arm and 11.4% in the chemotherapy arm. Among those who responded, the median duration of response was longer than 18 months with pembrolizumab compared with a response of 4.3 months with chemotherapy.
Pembrolizumab was associated with a lower rate of treatment-related adverse events than was chemotherapy (60.9% vs. 90.2%) and a lower rate of high-grade adverse events (15.0% vs. 49.4%). The most common adverse events with pembrolizumab were pruritus, fatigue, nausea, diarrhea, and decreased appetite.[43][Level of evidence A1]
In a single-arm phase II trial (NCT02335424) of pembrolizumab in 370 treatment-naïve, cisplatin-ineligible patients with locally advanced or metastatic urothelial carcinoma, the overall response rate was 29%. In patients with a PD-L1 CPS of at least 10%, the overall response rate was 51%.[44]
The median duration of response had not been reached. Eighty-two percent of responses lasted at least 6 months.
Ten percent of patients had a serious treatment-related adverse event, and one patient died of treatment-related adverse events. The most common high-grade adverse events were fatigue (2%), elevated alkaline phosphatase (1%), colitis (1%), and muscle weakness (1%).[44][Level of evidence C3]
Atezolizumab
Atezolizumab is a humanized monoclonal antibody that binds to PD-L1 and prevents it from binding to its receptors PD-1 or B7-1. Clinical trials have reported that atezolizumab acts against urothelial carcinoma, but it has not shown prolonged OS or improved quality of life. The only randomized controlled trial testing atezolizumab reported no significant difference in OS compared with second-line chemotherapy.
The FDA approved atezolizumab for patients with locally advanced or metastatic urothelial carcinoma who fall into one of the following three categories:
Cisplatin-ineligible and have tumors that express PD-L1 (at least 5% of the tumor area covered by tumor-infiltrating immune cells that stain for PD-L1).
Cisplatin- and carboplatin-ineligible.
Progression of disease after treatment with platinum-based chemotherapy.
It is important to note that in 2018, the FDA issued an alert that preliminary data from two ongoing trials showed shorter survival in first-line therapy trials comparing pembrolizumab or atezolizumab with cisplatin or carboplatin-based therapy. As a result, the labels were amended to restrict use of both agents to the three categories above.
Evidence (atezolizumab):
The IMvigor211 trial (NCT02302807) is a randomized controlled trial that compared atezolizumab with second-line chemotherapy (docetaxel, paclitaxel, or vinflunine) in 931 patients with locally advanced or metastatic urothelial carcinoma who were previously treated with platinum-containing chemotherapy.[45] The trial design specified that OS would be primarily assessed in patients with tumors in which at least 5% of cells stained for PD-L1.
The median OS was 11.1 months for atezolizumab versus 10.6 months for chemotherapy in patients with at least 5% of tumor cells staining for PD-L1 (P = .41).[45][Level of evidence A1]
Response rates were also similar: 23% with atezolizumab and 22% with chemotherapy.
Patients receiving atezolizumab had a lower rate of high-grade toxicity (20% vs. 43%) and a lower rate of treatment discontinuation resulting from adverse events (7% vs. 18%).
A multicenter, single-arm trial (NCT0108652) included 315 cisplatin-ineligible patients or patients who were previously treated with platinum-based chemotherapy and who had inoperable locally advanced or metastatic urothelial carcinoma. Patients received atezolizumab (1,200 mg IV every 21 days). The following results were reported:[41][Level of evidence C2]
The overall response rate was 15%.
With a median follow-up of 11.7 months, 38 of 45 responders (84%) had an ongoing response.
The response rate was 27% in those with PD-L1 expression of at least 5%, 10% in those with PD-L1 expression of 1% to 5%, and 8% in those with PD-L1 expression of less than 1%.
Grade 3/4 adverse events were reported in 16% of patients, and high-grade immune-related adverse events were reported in 5% of patients.
Similarly, a study (NCT02108652) of 123 previously untreated patients with cisplatin-ineligible, locally advanced metastatic urothelial carcinoma who were treated with atezolizumab reported that at a median follow-up of 17.2 months, the objective response rate was 23%, and 9% had complete responses.[42][Level of evidence C2]
Of the 27 responses, 19 were ongoing at the time of data analysis. Median OS was 15.9 months.
High-grade adverse events were reported in 16% of patients, 8% of patients discontinued treatment because of the adverse events, and there was one treatment-related death.
Nivolumab
Nivolumab is a fully human immunoglobulin G4 PD-1 immune checkpoint inhibitor antibody that blocks interaction between PD-L1 and PD-L2 with PD-1. There are no published controlled trials and thus no data regarding whether nivolumab results in longer survival or improved quality of life.
Evidence (nivolumab):
A multicenter trial (NCT01928394) included 86 patients with metastatic urothelial carcinoma whose disease progressed after platinum-based chemotherapy. Patients received nivolumab (3 mg/kg IV every 2 weeks).[40][Level of evidence B4]
With a minimum follow-up of 9 months and a median follow-up of 15 months, 24% had an objective response, and 22% had grade 3 or 4 adverse events.
The most common adverse events were elevated lipase or amylase, fatigue, rash, dyspnea, lymphopenia, and neutropenia.
Another multicenter study (NCT02387996) of 270 patients with locally advanced or metastatic urothelial carcinoma that had progressed after treatment with platinum-based chemotherapy reported an objective response rate of 20%.[39][Level of evidence B4]
When evaluated by PD-L1 expression, the objective response rate was 28% in those with PD-L1 expression of 5% or greater; 24% in those with PD-L1 expression of 1% or greater; and 16% in those with PD-L1 expression of less than 1%.
Grade 3 to 4 adverse events were reported in 18% of patients.
There were three treatment-related deaths.
Avelumab
Avelumab is a monoclonal anti–PD-L1 antibody that has shown activity against urothelial carcinoma. A randomized controlled trial reported an OS benefit from maintenance avelumab when given after platinum-based chemotherapy in patients whose cancer did not progress during chemotherapy.
Evidence (avelumab):
A phase III study (NCT02603432) evaluated maintenance avelumab (10 mg/kg IV every 14 days) in patients with metastatic urothelial carcinoma who had not progressed during treatment with first-line chemotherapy with gemcitabine combined with either cisplatin or carboplatin. After four to six cycles of chemotherapy, 700 patients were randomly assigned to receive either best supportive care (control arm) or best supportive care plus maintenance avelumab (avelumab arm).[46][Level of evidence A1]
The 1-year OS rate was 71.3% in the avelumab arm compared with 58.4% in the control arm (HR, 0.69; 95% CI, 0.56–0.86).
The OS benefit was limited to patients whose tumors were PD-L1-positive. The OS in patients with PD-L1–negative tumors was not significantly different between the two arms.
Patients with PD-L1–positive tumors had a 1-year OS rate of 79.1% in the avelumab arm and 60.4% in the control arm (HR, 0.56; 95% CI, 0.40–0.79).
In the overall study population, the median PFS was 3.7 months for patients in the avelumab arm and 2.0 months for patients in the control arm (HR, 0.62; 95% CI, 0.52–0.75). In patients with PD-L1–positive tumors, the median PFS was 5.7 months with avelumab and 2.1 months with best supportive care alone (HR, 0.56; 95% CI, 0.43–0.73).
Grade 3 or higher adverse events were reported for 47.4% of patients in the avelumab arm and 25.2% of patients in the control arm. Most adverse events with avelumab were immune related, and 9% of patients who received avelumab were treated with high-dose glucocorticoids for these events.
A study (NCT01772004) of avelumab (10 mg/kg IV every 14 days) in 249 patients with metastatic urothelial carcinoma who had progressed after treatment with platinum-based chemotherapy reported the following results:[47,48][Level of evidence C3]
Among the 161 patients with at least 6 months of follow-up, the overall response rate was 17%, and response was ongoing in 23 of 28 responders with a median follow-up of 7.3 months. Six percent of the patients had a complete response.
The overall response rate was 25.0% in patients with at least 5% of tumor cells staining for PD-L1 and 14.7% for those with less than 5% PD-L1 positivity.
The median progression-free survival was 6.3 weeks; 23% of the patients were progression free at 24 weeks.
A treatment-related adverse event was reported in 66.7% of patients, including 8.4% of patients with high-grade adverse events. There was one treatment-related death from pneumonitis. High-grade immune-related adverse events were reported in 2.4% of patients.
Durvalumab
Durvalumab is an anti–PD-L1 monoclonal antibody that has shown activity against urothelial carcinoma. There are no published controlled trials and no data demonstrating either longer survival or improved quality of life with this agent.
Evidence (durvalumab):
The efficacy of durvalumab (10 mg/kg IV every 14 days) was assessed in a study (NCT01693562) of 191 patients with locally advanced or metastatic urothelial carcinoma whose disease had progressed while they were on chemotherapy or who were either ineligible for or unwilling to be treated with chemotherapy.[49][Level of evidence C3]
With a median follow-up of 5.78 months, the overall response rate was 17.8%.
The response rate was 27.6% in patients with high expression of PD-L1 compared with 5.1% in patients with low or no PD-L1 expression.
High-grade adverse events were reported in 6.8% of patients, including 2.1% with high-grade immune-mediated adverse events.
Targeted therapy
Ramucirumab
Ramucirumab is an immunoglobulin G1 monoclonal antibody that blocks the vascular endothelial growth factor receptor-2 (VEGFR-2). The FDA approved ramucirumab for patients with gastric carcinoma and gastroesophageal junction adenocarcinoma, but not for patients with bladder cancer.
Evidence (ramucirumab):
Docetaxel chemotherapy plus ramucirumab was compared with docetaxel plus placebo in a double-blind, multicenter, randomized controlled phase III trial in 530 patients with metastatic urothelial carcinoma that had progressed after treatment with platinum-based chemotherapy. Forty-five patients (8.5%) had previously been treated with immunotherapy.[50][Level of evidence B1]
OS was not significantly different between the two arms.
The median PFS was 1.3 months (39 days) longer in the ramucirumab arm compared with the placebo arm (4.1 months vs. 2.8 months; HR, 0.696; 95% CI, 0.573–0.845, P = .0002).
The overall response rate was 26% in the ramucirumab arm and 14% in the placebo arm.
Treatment was discontinued because of adverse events in 19% of patients who received docetaxel plus ramucirumab and 8% of patients who received docetaxel plus placebo.
Grade 3 or higher adverse events were reported in 48% of patients in the ramucirumab arm and 41% of patients in the placebo arm. Adverse events included febrile neutropenia, epistaxis, hypertension, hematuria, and proteinuria. Sepsis occurred in 2% of patients who received ramucirumab, and no patients who received placebo.
Enfortumab vedotin
Enfortumab vedotin is a type of targeted therapy called an antibody-drug conjugate. Antibody-drug conjugates consist of a monoclonal antibody chemically linked to a drug. The monoclonal antibody part of enfortumab vedotin binds to a protein called nectin-4, which is found on the surface of most bladder cancer cells. The antibody is chemically linked to monomethyl auristatin E, or MMAE, a type of chemotherapy drug called a microtubule inhibitor. Once the conjugate is taken up by cells, the drug stops them from dividing and leads to their death.
The FDA approved enfortumab vedotin for patients with metastatic urothelial carcinoma that has progressed after treatment with both platinum-based first-line chemotherapy and second-line therapy with an immune checkpoint inhibitor. The approval was based on a single-arm trial of 125 patients with metastatic urothelial carcinoma.[51]
Evidence (enfortumab vedotin):
In a single-arm trial, 125 patients with metastatic urothelial carcinoma were treated with enfortumab vedotin.[51]
There was a 44% overall response rate and a 12% complete response rate.
The median duration of response was 7.6 months.
Adverse events included fatigue (50%), peripheral neuropathy (50%), alopecia (49%), rash (48%), decreased appetite (44%), and dysgeusia (40%).
Because there was no control arm, this study could not demonstrate an improvement in OS or quality of life. A follow-up phase III trial is under way to assess the benefits of this medication.
Erdafitinib
Erdafitinib (JNJ-42756493) is a potent tyrosine kinase inhibitor of fibroblast growth factor receptors 1–4. The FDA approved erdafitinib for patients with urothelial carcinoma that has a mutation in one of the four fibroblast growth factor receptor genes and that has progressed after receiving chemotherapy.
Roughly 20% of metastatic urothelial carcinomas of the bladder have mutations of FGFR, as do 35% of urothelial carcinomas of the ureters and renal pelvis.
Evidence (erdafitinib):
A phase II trial included patients with metastatic urothelial carcinoma whose disease had progressed during or after systemic chemotherapy.[52] To be eligible for the study, patients were required to have tumors that had mutations in FGFR3 or an FGFR2::FGFR3 gene fusion. The trial was originally designed as a randomized phase II trial comparing continuous with intermittent treatment, but after an interim safety analysis, the trial was converted to a single-arm study of continuous treatment with dose escalation. The published analysis focuses on this latter phase of the study, referred to as the "selected-regimen group." The selected-regimen group consisted of 99 patients, 74 with an FGFR3 mutation and 25 with an FGFR2::FGFR3 gene fusion.
The response rate by independent radiological review was 34%.
The response rate was higher among the patients with FGFR3 mutations than among the patients with FGFR2::FGFR3 gene fusions.
Grade 3 adverse events that affected at least 10% of patients included stomatitis and hyponatremia. The most common adverse events of any grade were hypophosphatemia (77%), stomatitis (58%), diarrhea (51%), dry mouth (46%), decreased appetite (38%), and dysgeusia (37%).
Surgery for new superficial or localized tumors
Treatment of new superficial or locally invasive tumors that develop in the setting of previous conservative therapy for superficial bladder neoplasia has been discussed earlier in stage I in this summary.
Palliative therapy
Palliative radiation therapy should be considered for patients with symptomatic tumors.
Clinical trials
Recurrent or progressive disease in distant sites or after definitive local therapy has an extremely poor prognosis, and patients should consider clinical trials whenever possible.
