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]
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.
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:
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.
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.
Increasing age is the most important risk factor for most cancers. Other risk factors for bladder cancer include the following:
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.
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.
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.
The major prognostic factors in carcinoma of the bladder are the following:
Among nonmuscle-invasive cancers, the following factors are also prognostic:[21]
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.
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.[23-25] 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.
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.[28-31]
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.
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:
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]
The American Joint Committee on Cancer (AJCC) has designated staging by TNM (tumor, node, metastasis) classification to define bladder cancer.[3]

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).[1-7]
Subsequent therapy is based on risk and typically consists of one of the following:[6-9]
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.[10-13] Other treatment approaches include the following:
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]
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.[20-22] Fluoropyrimidine avoidance or a dose reduction of 50% may be recommended based on the patient's DPYD genotype and number of functioning DPYD alleles.[23-25] 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]
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:[2-6]
Treatment options for stage 0 bladder cancer include the following:
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):
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.[6,11-13] 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.[14-18] 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.[20-22]
Evidence (TUR with fulguration followed by an immediate postoperative instillation of intravesical chemotherapy followed by periodic intravesical instillations of BCG):
Intravesical chemotherapy
Intravesical BCG with maintenance BCG treatments
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 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 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.[32-35]

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:[2-6]
Treatment options for stage I bladder cancer include the following:
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]
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:
Evidence (routine repeat TUR):
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.
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.[6,13-15] 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.[16-20] 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):
Evidence (intravesical BCG with maintenance BCG treatments):
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):
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):
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 is used in selected patients with extensive or refractory superficial tumors.[35-43] 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):
Use our advanced clinical trial search to find NCI-supported cancer clinical trials that are now enrolling patients. The search can be narrowed by location of the trial, type of treatment, name of the drug, and other criteria. General information about clinical trials is also available.
Treatment options for stage II bladder cancer and stage III bladder cancer include the following:
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 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.[1-4] 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.[5-8] 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.[6-8] Postoperative complications include ileus. Most men have erectile dysfunction after radical cystectomy; sexual dysfunction after this operation is also common in women.[10-12]
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.[13-16]
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.[6-8] 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]
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):
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.
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):
Evidence (adjuvant immunotherapy):
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.

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.[31-34]
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.

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 patients with T4b, N0, M0 disease include the following:
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.[2-4] 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):
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):
Cisplatin-based combination chemotherapy regimens are a standard of care option for patients with stage IV bladder cancer.[6-10] 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,[13-15] paclitaxel plus gemcitabine,[16-18] single-agent gemcitabine,[19,20] and single-agent paclitaxel.[21-23] Regimens of carboplatin, methotrexate, and vinblastine; carboplatin, epirubicin, methotrexate, and vinblastine; and paclitaxel, gemcitabine, and carboplatin have been studied but are not widely used.[24-27]
Evidence (chemotherapy alone):
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 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 include the following:
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. Pembrolizumab is an anti–PD-1 antibody that has been approved as monotherapy for patients with metastatic bladder cancer.

Evidence (chemotherapy plus immunotherapy):
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.[6-10] 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.

Ongoing studies are evaluating new chemotherapy combinations.
Evidence (chemotherapy):
Ongoing studies are evaluating new chemotherapy combinations.
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.[53-57] 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 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:
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):
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:

As a result, the labels were amended to restrict use of both agents to the three categories above.
Evidence (atezolizumab):
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):
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):
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):
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 may be indicated, not only for palliation of urinary symptoms, but also for preservation of renal function in candidates for chemotherapy.

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 patients with recurrent bladder cancer include the following:
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.[3-7] 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,[10-12] paclitaxel plus gemcitabine,[13-15] single-agent gemcitabine,[16,17] and single-agent paclitaxel.[18-20] 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.[21-24]
Evidence (combination chemotherapy):
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]
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.[38-42] 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.

Evidence (ramucirumab):
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):
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 (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):
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 radiation therapy should be considered for patients with symptomatic tumors.
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.
