Snapshot

The essentials in ~60 seconds — every line is drawn from the cited sources below.

What it is
Bladder cancer is commonly divided into non‑muscle‑invasive, muscle‑invasive nonmetastatic, and metastatic disease, and most cases are non‑muscle‑invasive. Urothelial carcinoma is the most common subtype. [1][2][3][4]
Survival
Muscle‑invasive bladder cancer carries a significant risk of death and represents approximately 25% of bladder cancer diagnoses. [5]
Standard treatment
Radical cystectomy with standard or extended pelvic lymph node dissection is the standard approach for nonmetastatic muscle‑invasive and localized invasive bladder cancer and remains the treatment of choice for treatment failures in NMIBC and for T2‑T4aN0M0 disease. Neoadjuvant cisplatin‑based chemotherapy is recommended for fit patients and is recommended to be discussed because it is described as improving overall survival. [6][7][8]
Key test
Testing for DNA mismatch repair (MMR)/MSI status, tumour mutational burden (TMB), and PD‑L1 can identify patients likely to respond to immune checkpoint inhibitors; pembrolizumab has approval for unresectable or metastatic solid tumours with MMR deficiency, MSI‑high, or high TMB after progression on at least one systemic treatment. [4]
Biggest challenge
The main clinical challenges are the risk of recurrence and progression after initial treatment and uncertainties about the optimal frequency and duration of cystoscopic surveillance. [9][2]

Risk factors

  • ▲ increases riskTobacco smoking [8][1]
  • ▲ increases riskWork‑related carcinogens [8]
  • ▲ increases riskArsenic exposure (high vs low) — top vs bottom tertile comparison [10]
  • ◆ mixedSecond‑hand smoke (SHS) exposure — Meta-analysis pooled RR 1.16 (95% CI: 0.95–1.43) among nonsmokers; stratified RRs 1.35 in males and 1.31 in females; limited evidence [11]
  • ▲ increases riskArsenic, cadmium, chromium, nickel (IARC group 1 metals) — IARC classified these as group 1 carcinogens; arsenic has sufficient evidence for bladder cancer in studies of high‑level exposure [10]

OverviewBladder cancer is commonly classified as non-muscle-invasive, muscle-invasive nonmetastatic, or metastatic disease; non-muscle-invasive disease accounts for the majority of cases. Urothelial carcinoma is the most common subtype (more than 90% of cases), and bladder cancer is the fourth most common cancer in the United States.5 points
  • Clinical classification of bladder cancer is commonly divided into three categories—non-muscle-invasive, muscle-invasive nonmetastatic, and metastatic disease—which differ in prognosis, management, and therapeutic aims; non-muscle-invasive bladder cancer accounts for the majority of cases. [1][2]
  • Bladder cancer is the fourth most common cancer in the United States, and urothelial carcinoma is the most common subtype. [3][4]
  • Cystoscopy is the standard method for follow-up of non-muscle-invasive bladder cancer; a systematic review of surveillance schedules included 8 articles and the studies included a total of 30,600 patients, but uncertainties remain about optimal frequency and duration of surveillance. [2]
  • Pure adenocarcinomas of the bladder are rare and represent less than 2% of all bladder cancers. [4]
  • Surgical treatments differ between primary bladder adenocarcinoma (PBAC) and urachal carcinoma (UrC): radical cystectomy is recommended for PBAC, while partial cystectomy with excision of the median umbilical ligament and umbilicus is preferred for UrC. [4]
EpidemiologyBladder cancer is a common cancer—among the more common cancers in the United States and the 10 th most frequently diagnosed cancer worldwide. Major risk factors include tobacco smoking and occupational carcinogens, and higher arsenic exposure has also been associated with increased risk.6 points

  • “Arsenic level was also associated with an increased risk of bladder cancer (RR, 1.60; 95% CI, 1.13-2.27; I2 = 76.0%; P < .001 for heterogeneity)”
  • “Stratified analyses by sex showed no differences in risk of bladder cancer by sex, with an RR of 1.35 (95% CI: 0.86-2.13) in males and 1.31 (95% CI: 0.98-1.73) in females.”
  • “The overall pooled RR of bladder cancer for SHS exposure was 1.16 [95% confidence interval (CI): 0.95-1.43]”
  • Bladder cancer is the 10 th most frequently diagnosed cancer worldwide. [11]
  • The most common urologic cancers are prostate, kidney, and bladder. [10]
  • Higher arsenic exposure has been associated with an increased risk of bladder cancer (top vs bottom tertile comparison). [10]
  • Bladder cancer is among the more common cancers in the United States. [1]
  • Smoking and work-related carcinogens are described as the most important risk factors for bladder cancer. [8]
  • While tobacco smoking is a well-established risk factor for bladder cancer, the association between second-hand smoke (SHS) exposure and bladder cancer remains less clear: a meta-analysis that included twelve studies (eight case-control and four cohort), involving approximately 1200 bladder cancer cases, reported an overall pooled relative risk (RR) of bladder cancer for second-hand smoke exposure of 1.16 (95% CI: 0.95-1.43) among nonsmokers; stratified analyses by sex showed RRs of 1.35 (95% CI: 0.86-2.13) in males and 1.31 (95% CI: 0.98-1.73) in females, higher risks were observed in studies conducted in Africa and Asia, and the authors noted a relatively limited number of cases and studies and called for further research with greater statistical power and improved exposure assessment. [11]
Key biomarkersSeveral tissue and blood/urine biomarkers are used or under discussion in bladder cancer, including TMB, MSI, MMR, PD-L1, and TERT promoter mutations, and guideline statements on urine markers have recently been updated. Molecular profiling may help direct therapy by matching treatments to tumor-specific mechanisms and targets, and the PD-1 inhibitor pembrolizumab has a tumor-agnostic approval tied to certain genomic biomarkers.8 points
  • Recent guideline updates included changes to statements on urine markers after diagnosis of bladder cancer. [13]
  • Urine cytology is reported to be useful for the diagnosis of high-grade tumor recurrence. [12]
  • The sources state that molecular medicine may improve clinical outcomes by directing therapy toward mechanisms and targets associated with an individual patient's tumor. [12]
  • The PD-1 inhibitor pembrolizumab was approved as the first tumor-agnostic treatment for unresectable or metastatic solid tumors with DNA MMR deficiency, MSI-high, or high TMB after progression on at least one systemic treatment. [4]
  • TMB, MSI, MMR and PD-L1 are known predictive markers of immune checkpoint inhibitor response. [4]
  • In urachal carcinoma (UrC), the top 10 mutated genes included TP53 (79%), KRAS (34%), SMAD4 (21%), DICER1 (15%), MYC (14%), GNAS (13%), LRP1B (11%), APC (10%), NF1 (9%), and ARID1A (8%). [4]
  • In primary bladder adenocarcinoma (PBAC), the top 10 frequently affected genes included TP53 (77%), KRAS (17%), SMAD4 (14%), TERT (14% overall when coding and promoter region data are combined), MYC (13%), CDKN2A (13%), ARID1A (11%), PI3KCA (9%), APC (8%) and FGF19 (8%). [4]
  • TERT promoter mutations have a high prevalence in urothelial carcinoma (UC) and urothelial carcinoma with glandular differentiation (UCg). [4]
Standard managementManagement depends on stage: non‑muscle‑invasive disease is established after complete, deep transurethral resection with risk stratification (EORTC) guiding intravesical therapies, while nonmetastatic muscle‑invasive and localized invasive disease are generally managed with radical cystectomy and lymph node dissection. Neoadjuvant cisplatin‑based chemotherapy is recommended for suitable/fit patients and current advice limits adjuvant chemotherapy to use within clinical trials.15 points
  • Radical cystectomy combined with standard or extended pelvic lymph node dissection (removal of the bladder including regional lymph nodes) is described as the standard treatment for nonmetastatic muscle‑invasive and localized invasive bladder cancer and is stated to remain the treatment of choice for treatment failures in NMIBC and for T2‑T4aN0M0 disease. [6][8][7]3 sources
  • Neoadjuvant cisplatin‑based chemotherapy is recommended for patients in suitable general health with satisfactory renal function (fit patients) and is recommended to be discussed because it is described as improving overall survival. [6][8]
  • An orthotopic bladder substitute/enterocystoplasty is an option to offer to both male and female patients lacking contraindications and when urethral recutting is negative on extemporaneous examination; when enterocystoplasty is not appropriate, transileal cutaneous ureterostomy is recommended as the method of urinary diversion. [6][7]
  • The diagnosis of non‑muscle‑invasive bladder cancer (Ta, T1, or CIS) is made after complete and deep tumour resection; bladder photodynamic (enhanced) diagnosis and performing a second TURBT 4 to 6 weeks later can improve the initial diagnosis. [9]
  • Risk of recurrence and/or tumour progression in NMIBC is assessed using the EORTC score, and patients are stratified to guide adjuvant options such as intravesical chemotherapy, BCG, or cystectomy for unresponsive disease. [9]
  • Enhanced cystoscopy (photodynamic diagnosis) was among the topics with updated statements in the recent NMIBC guideline amendment. [13]
  • Performing the first cystoscopy within 3–4 months after transurethral resection of the bladder showed better outcomes, while excessively early or delayed cystoscopy procedures were reported to increase the risk of recurrence and progression. [2]
  • In low‑risk patients some studies support discontinuing surveillance after 5 years without recurrence, whereas other studies recommend prolonging surveillance in patients with risk factors such as smoking or multiple tumours. [2]
  • CT‑Urography coupled with chest CT scans is used to assess the extent of muscle‑invasive bladder cancer, and multiparametric pelvic MRI may be an alternative imaging approach. [6]
  • Current advice recommends the use of adjuvant chemotherapy only within clinical trials. [7]
  • Guideline updates have addressed neoadjuvant and adjuvant chemotherapy, radical cystectomy, pelvic lymphadenectomy, and multi‑modal bladder‑preserving therapy. [5]
  • All patients undergoing surgery should be included in an enhanced recovery after surgery (ERAS) protocol. [6]
  • Multimodality treatment is noted as an alternative for selected, well‑informed, and compliant patients when cystectomy is not an option. [8]
  • For patients with metastatic disease, cisplatin‑containing combination chemotherapy is recommended; for unfit patients, carboplatin‑containing combination chemotherapy or single agents are described as options. [8]
  • Compared with open radical cystectomy, minimally invasive techniques (laparoscopic and robot‑assisted radical cystectomy) were associated with reduced intraoperative blood loss and lower transfusion rates but required longer operative time; laparoscopic radical cystectomy was associated with a potentially greater likelihood of enhanced postoperative recovery and fewer complications though the evidence is limited and heterogeneous, robot‑assisted radical cystectomy did not demonstrate consistent superiority over laparoscopy in perioperative measures, and short‑term oncological surrogate outcomes were similar across open, laparoscopic, and robot‑assisted approaches.

Staging & riskNon-muscle-invasive bladder cancer includes Ta, T1, and carcinoma in situ (CIS). Staging of muscle-invasive disease relies on imaging (commonly CT urography with chest CT; MRI, including multiparametric pelvic MRI, can assess local extent) and evaluation of the lower urinary tract is performed with white-light cystoscopy (with fluorescence-aided cystoscopy and narrow-band imaging as adjuncts); CT is preferred for pulmonary assessment.3 points
  • Guidelines recommend imaging for staging of muscle-invasive bladder cancer, typically CT urography with chest CT; MRI (including multiparametric pelvic MRI) can be used to assess local extent, and computed tomography is preferred for pulmonary evaluation. [6][8]
  • Non-muscle-invasive bladder cancer includes Ta, T1, and carcinoma in situ (CIS) presentations. [9]
  • White-light cystoscopy is the gold standard for evaluation of the lower urinary tract and is described as the most cost-effective method to detect recurrence of bladder cancer; fluorescence-aided cystoscopy and narrow-band imaging can aid evaluations as adjuncts. [12]
PrognosisPrognosis in bladder cancer varies by stage and specific pathological features: muscle-invasive disease (approximately 25% of diagnoses) carries a significant risk of death, while stromal invasion by urothelial carcinoma of the prostate is associated with a poor prognosis. Risk stratification tools such as the EORTC score are used for recurrence and progression risk in NMIBC, and evidence finds comparable short-term surrogate oncological endpoints between minimally invasive and open radical cystectomy approaches while long-term outcomes remain uncertain; in high-risk patients different surveillance schedules showed no differences in mortality or progression.5 points
  • The EORTC score is used to assess the risk of recurrence and/or tumour progression in NMIBC. [9]
  • Muscle-invasive bladder cancer carries a significant risk of death and represents approximately 25% of bladder cancer diagnoses. [5]
  • Stromal invasion by urothelial carcinoma of the prostate is stated to carry a poor prognosis. [16]
  • Short-term surrogate oncological endpoints after radical cystectomy approaches appeared comparable between minimally invasive and open surgery, but long-term outcomes remain to be determined. [14]
  • In high-risk patients, across the different surveillance schedules analysed, no differences were found in terms of mortality or progression. [2]
What we don't know yetSeveral evidence gaps remain in bladder cancer care, including limits in the underlying evidence cited by guidelines, lack of high-level data for rare histologies, uncertainties about optimal surveillance and long-term surgical outcomes, heterogeneity in maintenance chemotherapy data, and incomplete understanding of some environmental and second‑hand smoke exposures. Guideline authors and study authors call for prospective, long-term, and better‑powered studies to address these gaps.7 points
  • Guideline authors note limitations in the evidence base and state that future studies are essential to refine recommendations and improve patient care; recommendations were developed by balancing evidence quality, benefits and harms, and patient values. [13][17]
  • Prospective clinical trials often exclude rare histological types such as PBAC and UrC, leading to a lack of high-level evidence and established systemic therapeutic recommendations for these subtypes. [4]
  • The effects of low-level environmental exposure to nonessential elements on urologic cancer risk remain poorly understood. [10]
  • Maintenance effects reported for Gem/Doce were derived from between-study comparisons and should be interpreted cautiously due to heterogeneity in maintenance protocols and adherence. [15]
  • Long-term oncological outcomes after minimally invasive versus open radical cystectomy remain to be determined. [14]
  • There are uncertainties regarding the optimal frequency and duration of cystoscopic surveillance after initial surgery for NMIBC; prospective and long-term studies are required to define optimal surveillance schedules, to optimise resources, and to reduce the burden on patients. [2]
  • For the association between second-hand smoke and bladder cancer, authors call for further research with greater statistical power and improved exposure assessment to better clarify the role of second‑hand smoke exposure. [11]
Safety & interactionsGuidelines recommend using comorbidity rather than age when deciding on radical cystectomy. The International Agency for Research on Cancer classifies arsenic, cadmium, chromium, and nickel as group 1 carcinogens, and identifies arsenic as a bladder carcinogen with sufficient evidence in humans from studies of high-level environmental or occupational exposure.2 points
  • The guidelines state that comorbidity, rather than age, should be used when deciding on radical cystectomy. [8]

Common questions

What is Bladder Cancer?

Bladder cancer is commonly classified as non-muscle-invasive, muscle-invasive nonmetastatic, or metastatic disease; non-muscle-invasive disease accounts for the majority of cases. Urothelial carcinoma is the most common subtype (more than 90% of cases), and bladder cancer is the fourth most common cancer in the United States.

How common is Bladder Cancer?

Bladder cancer is a common cancer—among the more common cancers in the United States and the 10 th most frequently diagnosed cancer worldwide. Major risk factors include tobacco smoking and occupational carcinogens, and higher arsenic exposure has also been associated with increased risk.

Which biomarkers are important in Bladder Cancer?

Several tissue and blood/urine biomarkers are used or under discussion in bladder cancer, including TMB, MSI, MMR, PD-L1, and TERT promoter mutations, and guideline statements on urine markers have recently been updated. Molecular profiling may help direct therapy by matching treatments to tumor-specific mechanisms and targets, and the PD-1 inhibitor pembrolizumab has a tumor-agnostic approval tied to certain genomic biomarkers.

What is the biology of Bladder Cancer?

These adenocarcinomas frequently harbor mutations in cell membrane receptor genes that have been identified as potential molecular targets for personalized therapy. Urachal carcinoma (UrC) and primary bladder adenocarcinoma (PBAC) show similar mutational profiles, sharing 15 of their top 30 most frequently affected genes.

How is Bladder Cancer treated?

Management depends on stage: non‑muscle‑invasive disease is established after complete, deep transurethral resection with risk stratification (EORTC) guiding intravesical therapies, while nonmetastatic muscle‑invasive and localized invasive disease are generally managed with radical cystectomy and lymph node dissection. Neoadjuvant cisplatin‑based chemotherapy is recommended for suitable/fit patients and current advice limits adjuvant chemotherapy to use within clinical trials.

What treatments are studied for Bladder Cancer?

35 therapeutic or management items are reported across chemotherapy, immunotherapy, procedural/device, and other categories (including surgical and diagnostic approaches).

Biological activities and therapeutic potential of soy isoflavones: a focus on anticancer activity

Molecular biology reports · May 2026 · narrative review

Genisteinbreast cancerovarian cancerprostate cancergliomaneuroblastomahepatocellular carcinomalung cancerbladder cancerosteosarcomarhabdomyosarcoma

This is a narrative review of the biological activities and potential therapeutic roles of soy isoflavones (including genistein and daidzein). The authors summarize proposed anticancer mechanisms (estrogen receptor modulation, apoptosis, anti-angiogenesis, epigenetic effects, etc.) and report that in vitro and in vivo studies have shown promising results across a range of tumor types. They conclude that further research—especially studies combining isoflavones with established chemotherapeutics—is needed.

Studied with: chemotherapeutic agents.

Key findings
  • Soy isoflavones (genistein, daidzein) have estrogenic and non-estrogenic activities including anti-inflammatory, antioxidant, and immunomodulatory effects.
  • Proposed anticancer mechanisms include modulation of estrogen receptors, copper ion-dependent induction of cell death, promotion of apoptosis, inhibition of angiogenesis and metastasis, regulation of epigenetic processes, and effects on platelet function.
  • Because of estrogen receptor interactions, isoflavones have been studied particularly in hormone-dependent cancers such as breast, ovarian, and prostate cancer.
  • In vitro and in vivo studies have reported promising results in multiple malignancies (gliomas, neuroblastoma, hepatocellular carcinoma, lung and bladder cancers, osteosarcoma, rhabdomyosarcoma).
  • Authors recommend further investigation, particularly combining isoflavones with established chemotherapeutics, to evaluate potential synergy.
Limitations: This article is a narrative review and does not present new clinical trial data.; The evidence summarized is primarily preclinical (in vitro and in vivo) with no clinical trial data provided in the abstract.; Mechanistic proposals are not proven clinical effects and require further experimental and clinical validation.; Safety and efficacy in patients, optimal dosing, and interactions with standard therapies are not established in this review..

Narrow Bandgap Schottky Heterojunction Sonosensitizer with High Electron-Hole Separation Boosted Sonodynamic Therapy in Bladder Cancer

Advanced materials (Deerfield Beach, Fla.) · Jun 2024

bladder cancer

The authors developed a TiO2-Ru-PEG Schottky heterojunction sonosensitizer and evaluated it for sonodynamic therapy against bladder cancer. DFT and experimental data indicated a reduced bandgap and improved electron-hole separation, leading to enhanced ROS generation under ultrasound and causing cell cycle arrest and apoptosis in bladder tumor cells. In vivo, TiO2-Ru-PEG improved outcomes in subcutaneous and orthotopic bladder tumor models and was reported to show good safety.

Studied with: ultrasound.

Key findings
  • DFT calculations and experiments showed that deposition of ruthenium within the TiO2 shell reduced the bandgap of TiO2-Ru-PEG due to formation of a Schottky heterojunction with a crystalline-amorphous interface.
  • TiO2-Ru-PEG enhanced oxygen adsorption and efficient separation of electron-hole pairs.
  • Under ultrasound irradiation, TiO2-Ru-PEG promoted generation of reactive oxygen species (ROS).
  • In vitro, increased ROS generation was associated with cell cycle arrest and apoptosis of bladder tumor cells.
  • In vivo, TiO2-Ru-PEG 'boosted' both subcutaneous and orthotopic bladder tumor models and was reported to exhibit good safety.
Limitations: Preclinical study only (cellular experiments and in vivo tumor models); no human data reported in the abstract.; Abstract provides no sample sizes, dosing, administration route, or statistical details.; Species and detailed experimental conditions for the in vivo models are not specified in the abstract.; Safety is asserted but detailed toxicity data and endpoints are not reported in the abstract..

What the research shows for Bladder Cancer

A plain-language summary of the reviewed studies OncoForge tracks for Bladder Cancer. It reports what those studies described, not a claim that any compound or therapy helps or harms Bladder Cancer. Most of this evidence is early, and findings often conflict.

  • A review of nucleobindin-2/nesfatin-1 (NUCB2/NESF-1) summarizes published reports in several cancers (breast, colon, prostate) that higher expression has been associated with worse outcomes and with increased cancer cell proliferation, migration, and invasion; the review notes conflicting findings across studies and characterizes the overall strength as limited.
  • A narrative review of the adaptor protein CRKL reports that CRKL is overexpressed in many tumor types and is described in the literature as promoting aggressive or malignant behaviors; the authors suggest potential diagnostic or therapeutic interest but rate evidence as limited.
  • Both articles are literature reviews that compile prior preclinical and observational studies (tumor tissue analyses, cell-line work, and some animal data) rather than presenting new randomized clinical-trial evidence.
  • Neither review provides data specific to bladder cancer in the papers supplied here, and the overall findings across the reviewed studies are inconsistent and preliminary.

Supportive & alternative options discussed

  • Hyperthermia (heat): Also discussed as a supportive option for bladder cancer (for example, intravesical therapies combined with local heating), but this set of studies does not provide evidence for or against it.
  • Exercise / prehabilitation: Also discussed as a supportive option to improve general health and quality of life for people with bladder cancer; these reviews do not evaluate exercise interventions.
  • Mind–body (MBSR / CBT): Also discussed as a supportive approach (stress reduction, coping) in cancer care broadly; the provided studies do not address mind–body interventions in bladder cancer.
  • Acupuncture: Also discussed for symptom management (e.g., pain, nausea) in cancer care; the studies provided do not evaluate acupuncture for bladder cancer.
  • Ketogenic / metabolic therapy: Also discussed by some as a complementary dietary approach in cancer, but the reviewed articles do not provide data on ketogenic diets for bladder cancer.
  • Mistletoe (VAE): Also used as an adjunctive therapy by some patients with cancer in certain regions, but the current studies do not present evidence about mistletoe in bladder cancer.

What we don’t know yet

  • Do NUCB2/NESF-1 or CRKL have a role as biomarkers or therapeutic targets specifically in bladder cancer? The provided reviews do not establish this.
  • Are associations reported in other tumor types reproducible in bladder cancer tissue, cell models, or patients? There are no bladder-specific primary studies in these papers.
  • Would modifying NUCB2/NESF-1 or CRKL alter clinical outcomes in patients with bladder cancer? No clinical trials addressing this are reported here.
  • What assays, thresholds, or standardized methods would be needed to measure these proteins reliably in clinical samples? The reviews note variability but do not resolve it.
  • If these proteins were targeted, what dosing, delivery, safety, and long-term effects would be expected? These questions remain unanswered by the reviewed literature.
The evidence summarized in these reviews is preliminary and largely based on preclinical and observational studies in cancers other than bladder; it does not establish clinical relevance or support specific interventions for bladder cancer.
