BACKGROUND AND OBJECTIVE: Bladder cancer (BCa) imposes a substantial economic burden on health care systems and patients. Understanding these financial implications is crucial for effective resource allocation and optimization of treatment cost effectiveness. Here, we aim to systematically review and analyze the financial burden of BCa from the health care and patient perspectives. METHODS: A Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA)-compliant systematic review was conducted, searching PubMed/Medline, Embase, and public sources for studies evaluating the financial impact of BCa, encompassing costs, cost effectiveness, and financial toxicity (FT). KEY FINDINGS AND LIMITATIONS: Non-muscle-invasive BCa (NMIBC) incurs significant costs for surveillance and treatment, with costs exceeding $200 000 after 5 yr for high-risk NMIBC patients progressing after bacillus Calmette-Guerin (BCG) treatment (including inpatient, outpatient, and physician service expenses). Muscle-invasive BCa generates substantial costs from radical cystectomy (RC) and neoadjuvant chemotherapy, averaging $30 000-40 000 from surgical costs of RC, with additional expenses in case of complications. Trimodal therapy has higher costs (1-yr management cost >$200 000) than RC because of higher outpatient, radiology, and medication costs. Metastatic BCa incurs the highest financial burden, with systemic therapy costs ranging from $40 000 to over $100 000 per five-cycle course, increasing further with combination therapies (ie, enfortumab vedotin and pembrolizumab), treatment-related toxicity, and supportive care. FT is particularly prevalent among younger, less educated, and minority populations. CONCLUSIONS AND CLINICAL IMPLICATIONS: BCa treatment, particularly in advanced stages, imposes a substantial economic burden. Innovations in care, while improving oncologic outcomes, necessitate detailed cost-effectiveness assessments. Addressing these economic challenges is essential for optimizing BCa management, targeting patients at a higher risk of FT, and improving patient quality of life.

BACKGROUND AND OBJECTIVE: Bacillus Calmette-Guérin (BCG) is the standard treatment in patients harboring high-risk (HR) non-muscle-invasive bladder cancer (NMIBC). However, BCG therapy faces frequent adverse events (AEs), limited efficacy, and ongoing shortages, leading to a low completion rate, access challenges, and high recurrence. In consequence, there is a growing interest in exploring alternative treatments, including immune checkpoint inhibitors, chemotherapy combinations, and novel intravesical therapies. This systematic review summarizes current prospective evidence on BCG and alternative treatment options for BCG-naïve HR-NMIBC patients (PROSPERO: CRD42024564900). METHODS: A systematic search in MEDLINE, EMBASE, Scopus, Web of Science, and Cochrane Library retrieved 1042 studies, of which 17 met the inclusion criteria (following the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines). KEY FINDINGS AND LIMITATIONS: In 12 studies on BCG-treated patients (n = 1418), recurrence-free survival (RFS) rates were 66-96% at 1-yr, 63-96% at 2-yr, and 39-66% at 5-yr follow-up. Progression-free survival (PFS) rates were 81-98% at 1-yr, 70-96% at 2-yr, and 70-84% at 5-yr follow-up. In nine studies focusing on patients treated with alternative strategies (n = 657), RFS rates were 51-99% at 1-yr, 48-88% at 2-yr, and 47-55% at 5-yr follow-up. PFS was 90-100% at 1-yr, 88-96% at 2-yr, and 84-93% at 5-yr follow-up. AE rates varied widely across studies, for both BCG and alternative treatments. Unfortunately, studies heterogeneity and a small sample sizes limit statistically meaningful conclusions. Twelve clinical trials are currently investigating new strategies for BCG-naïve HR NMIBC patients. CONCLUSIONS AND CLINICAL IMPLICATIONS: Alternative therapies for BCG-naïve HR NMIBC patients are emerging but need further validation. As challenges such as toxicity, cost, and long-term efficacy persist, ongoing trial results will be crucial in determining their role in future clinical practice.

OBJECTIVE: To evaluate the impact of discordant histological diagnoses between transurethral resection of bladder tumour (TURBT) and radical cystectomy (RC) on cancer-specific mortality (CSM) in patients with bladder cancer (BCa). PATIENTS AND METHODS: We relied on a multi-institutional database collecting data of patients with BCa who underwent TURBT and subsequent RC from nine centres between 2000 and 2023. We tested concordance rates between TURBT and RC in detecting urothelial carcinoma of the urinary bladder (UCUB) as well as non-UCUB hystological subtypes, using RC as the reference standard. Concordance was defined as the agreement between a specific histological subtype identified both at TURBT and RC and evaluated according to Cohen's kappa coefficient. Subsequently, survival analyses consisted of Kaplan-Meier plots and multivariable Cox regression (MCR) models addressing CSM according to concordance between TURBT and RC (namely, concordant vs discordant). RESULTS: Overall, 3160 patients were identified. Of these, 2762 (87%) harboured UCUB and 398 (13%) non-UCUB at TURBT vs 2481 (79%) UCUB and 679 (21%) non-UCUB at RC. There were 683 (21.6%) patients with a discordant diagnosis between TURBT and RC. The overall concordance in detecting non-UCUB subtypes was defined as fair concordance (Cohen's kappa coefficient: 0.32). In MCR models, a discordant diagnosis exhibited higher CSM relative to those with a concordant diagnosis (hazard ratio [HR] 1.3, 95% confidence interval [CI] 1.1-1.6; P = 0.002). In a sensitivity analysis including patients with UCUB not exposed to neoadjuvant chemotherapy, this survival disadvantage was even higher (HR 1.5, 95% CI 1.1-1.7; P = 0.04). CONCLUSIONS: A discordant histopathological diagnosis between TURBT and RC is associated with higher CSM rates, particularly in cases initially misdiagnosed as UCUB. However, we also observed a moderate concordance between TURBT and RC in identifying non-UCUB subtypes.

OBJECTIVE: To assess the oncological outcomes of patients with high-risk (HR) and very high-risk (VHR) non-muscle-invasive bladder cancer (NMIBC) treated with upfront radical cystectomy (RC) vs Bacillus Calmette-Guérin (BCG) instillations from a contemporary European multicentre cohort. PATIENTS AND METHODS: We conducted a retrospective analysis of 1491 patients diagnosed with HR- or VHR-NMIBC from a European multicentre database between 2015 and 2024. Patients were included if they received either upfront RC or at least five doses of BCG. A 1:1 propensity score matching (PSM) according to clinically relevant variables was applied. Progression was defined as muscle-invasive or metastatic disease. Cumulative incidence plots and multivariable competing risk regression models addressing cancer-specific mortality (CSM) were fitted. RESULTS: Among the 1221 patients with HR- (n = 1221 [90%]) or VHR-NMIBC (n = 121 [10%]), 87 (7.1%) underwent upfront RC. The median follow-up was 2.6 years. After PSM (87 vs 87 patients), the 5-year CSM rate was similar in patients treated with BCG (13%) vs their upfront RC counterparts (16%) (hazard ratio: 1.77, 95% confidence interval [CI] 0.66-4.73; P = 0.3). Of the 1134 patients who initially received BCG, 73 (6.6%) eventually required delayed RC, with 34 (47%) progressing to muscle-invasive bladder cancer before delayed RC. The 3-year CSM rate was comparable in upfront RC (13%) vs delayed RC (11%) among non-progressing patients (P = 0.3). However, patients who progressed before delayed RC had worse 3-year CSM relative to those who did not (13% vs 31%, hazard ratio: 0.32, 95% CI 0.13-0.83; P = 0.018). CONCLUSION: Within a European cohort of patients with HR- and VHR-NMIBC, upfront RC was rarely performed. Patients treated with BCG did not exhibit a CSM disadvantage relative to their upfront RC counterparts. After matching, long-term CSM was similar between BCG therapy and upfront RC. Delayed RC, led to worse outcomes if performed after progression, but matched upfront RC when performed before progression, underscoring importance of timely surgery.

OBJECTIVE: To evaluate the oncological efficacy and safety of sequential intravesical gemcitabine/docetaxel (Gem/Doce) therapy in a European cohort of patients with high-risk and very-high-risk non-muscle-invasive bladder cancer (NMIBC) after previous Bacillus Calmette-Guérin (BCG) treatment. MATERIALS AND METHODS: Data were retrospectively collected from 95 patients with NMIBC, treated with Gem/Doce at 12 European centres between 2021 and 2024. Patients previously treated with BCG who had completed a full induction course and received at least one follow-up evaluation were included. One-year disease-free survival (DFS), high-grade DFS and progression-free survival (PFS) were estimated using Kaplan-Meier curves. Adverse events (AEs) were recorded through medical interviews. RESULTS: Of 75 patients, 63 (84%) were classified as having high-risk and 12 (16%) as having very-high-risk NMIBC. Over a median (interquartile range) follow-up of 9 (5-14) months, 20 patients (27%) relapsed and five (6.7%) underwent radical cystectomy. The 1-year DFS was 73% (95% confidence interval [CI] 62-86%), 1-year high-grade DFS was 79% (95% CI 68-91%) and 1-year PFS was 95% (95% CI 90-100%). AEs occurred in 34 patients (45%), with six (8.7%) experiencing severe AEs. Limitations of the study include the short follow-up and variability in both treatment dwelling times and dosage across centres. CONCLUSION: The intravesical Gem/Doce regimen demonstrated promising short-term oncological outcomes and was well tolerated in this cohort of patients with high- and very-high-risk NMIBC previously treated with BCG. Prospective studies and randomised trials are awaited to define the ideal candidates for Gem/Doce therapy and to standardise treatment protocols.

OBJECTIVE: Sparse data exist on the impact of upper urinary tract (UUT) decompression on the risk of UUT recurrence in patients with bladder cancer (BCa). This study aims to evaluate whether Double J stenting (DJS) can increase the risk of UUT recurrence compared to percutaneous nephrostomy (PCN) placement. MATERIALS AND METHODS: We retrospectively analyzed data from 1550 patients with cTa-T3NanyM0 BCa who underwent radical cystectomy (RC) between at 12 tertiary care centers (1990-2020). Patients with complete follow-up, no prior history of UUT cancer, and who required UUT decompression for preoperative hydronephrosis were selected. Hydronephrosis grade was defined according to established scoring systems. UUT recurrence was diagnosed through imaging, urinary cytology, and confirmed by selective cytology and ureteroscopy when possible. Propensity scores were computed to determine overlap weights and balance groups. Kaplan-Meier analyses estimated UUT recurrence-free survival (RFS), cancer-specific (CSS), and overall survival (OS) before and after weighting. Cox regression analyses before and after weighting were fitted to predict UUT recurrence. RESULTS: Of 524 included patients, 132 (25%) and 392 (75%) patients were managed with DJS and PCN placement, respectively. Patients who received PCN had higher grade (≥ 3) of obstruction (34% vs. 14%) and pT3-4 tumors (70% vs. 36%) than patients with DJS. During a median follow-up of 19 months, 2-years UUT-RFS did not differ between groups (95% for PCN vs 92% for DJS, weighted HR 1.41, 95% CI, 0.55-3.59). There was no difference in 2-years weighted CSS (74% vs. 74%) and OS (67% vs 69%). Main limitations were the short follow-up and inclusion of patients uniquely undergoing RC. CONCLUSIONS: These results suggest that ureteral DJS does not increase the risk of developing UUT recurrence in BCa patients with hydronephrosis requiring UUT decompression. However, UUT recurrence was rare, and associations were weak, with findings susceptible to bias. Randomized trials are needed to validate these results.

BACKGROUND AND OBJECTIVE: Intravesical mitomycin C (MMC) instillations are recommended to prevent recurrence of intermediate-risk non-muscle-invasive bladder cancer (IR-NMIBC); however, the optimal regimen and dose are uncertain. Our aim was to assess the effectiveness of adjuvant MMC and compare different MMC regimens in preventing recurrence. METHODS: We performed a comprehensive search in PubMed, Scopus, and Web of Science in November 2023 for studies investigating recurrence-free survival (RFS) among patients with IR-NMIBC who received adjuvant MMC. Prospective trials with different MMC regimens or other intravesical drugs as comparators were considered eligible. KEY FINDINGS AND LIMITATIONS: Overall, 14 studies were eligible for systematic review and 11 for meta-analysis of RFS. Estimates of 1-yr, 2-yr, and 5-yr RFS rates were 84% (95% confidence interval [CI] 79-89%), 75% (95% CI 68-82%), and 51% (95% CI 40-63%) for patients treated with MMC induction plus maintenance, and 88% (95% CI 83-94%), 78% (95% CI 67-89%), and 66% (95% CI 57-75%) for patients treated with bacillus Calmette-Guérin (BCG) maintenance, respectively. Estimates of 2-yr RFS rates for MMC maintenance regimens were 76% (95% CI 69-84%) for 40 mg MMC (2 studies) and 66% (95% CI 60-72%) for 30 mg MMC (4 studies). Among the studies included, BCG maintenance provided comparable 2-yr RFS to 40 mg MMC with maintenance (78% vs 76%). RFS did not differ by MMC maintenance duration (>1 yr vs 1 yr vs <1 yr). CONCLUSIONS AND CLINICAL IMPLICATIONS: MMC induction and maintenance regimens seem to provide short-term RFS rates equivalent to those for BCG maintenance in IR-NMIBC. For adjuvant induction and maintenance, 40 mg of MMC appears to be more effective in preventing recurrence than 30 mg. We did not observe an RFS benefit for longer maintenance regimens. PATIENT SUMMARY: For patients with intermediate-risk non-muscle-invasive bladder cancer, bladder treatments with a solution of a drug called mitomycin C (MMC) seem to be as effective as BCG (bacillus Calmette-Guérin) in preventing recurrence after tumor removal. Further trials are needed for stronger evidence on the best MMC dose and treatment time.

PURPOSE: There is lack of evidence regarding the indication for re-transurethral resection of bladder tumor (reTURBT) for Ta high grade (HG) non-muscle invasive bladder cancer (NMIBC). This study aims to evaluate the oncological outcomes of patients with TaHG NMIBC to determine the benefit from performing reTURBT. METHODS: We relied on a multicenter cohort of 317 TaHG NMIBC from 12 centers who underwent TURBT and a subsequent complete Bacillus Calmette-Guérin induction from 2009 to 2021. Kaplan Meier analyses estimated recurrence free survival (RFS) and progression free survival (PFS) according to reTURBT. Sub-analyses evaluated PFS in patients with multiple risk factors indicating necessity for reTURBT according to international guidelines (multifocality, size > 3 cm, recurrent cancer, carcinoma in situ, lymph vascular invasion, histological variant, incomplete and absence of muscle layer at index TURBT). Multivariable cox-regression analysis predicted recurrence and progression. RESULTS: Of the 317 patients, 123 (39%) underwent reTURBT, while 194 (61%) did not. Residual disease was detected in 46% of cases, with a 3.2% upstaging rate. Median follow-up was 30 months. The 3-year RFS was higher in patients who underwent reTURBT (79% vs. 58%, p < 0.001), but no significant difference was observed in PFS. ReTURBT reduced the risk of recurrence [multivariable hazard ratio: 0.45, 95% Confidence interval (CI) 0.29-0.71]. Among patients who did not undergo reTURBT, those with ≥ 2 risk factors had lower 3-year PFS (73% vs. 92%, p < 0.001) than those with 0-1 risk factor, whereas no difference in 3-year PFS was observed in patients who underwent reTURBT regardless of the number of risk factors (85% vs. 87%, p = 0.8). CONCLUSION: ReTURBT demonstrated efficacy in reducing recurrence among patients with TaHG NMIBC, yet its impact on progression remained uncertain. Our study underscores the importance of adhering to current international guidelines, particularly for patients with multiple risk factors indicating necessity for reTURBT.

BACKGROUND: In contrast to other cancers, the concept of oligometastatic disease (OMD) has not been investigated in bladder cancer (BC). OBJECTIVE: To develop an acceptable definition, classification, and staging recommendations for oligometastatic BC (OMBC) spanning the issues of patient selection and the roles of systemic therapy and ablative local therapy. DESIGN, SETTING, AND PARTICIPANTS: A European consensus group of 29 experts, led by the European Association of Urology (EAU), the European Society for Radiotherapy and Oncology (ESTRO), and the European Society of Medical Oncology (ESMO), and including members from all other relevant European societies, was established. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: A modified Delphi method was used. A systematic review was used to build consensus questions. Consensus statements were extracted from two consecutive surveys. The statements were formulated during two consensus meetings. Agreement levels were measured to determine if consensus was achieved (≥75% agreement). RESULTS AND LIMITATIONS: The first survey included 14 questions and the second survey had 12. Owing to a considerable lack of evidence, which was the major limitation, definition was limited in the context of de novo OMBC, which was further classified as synchronous OMD, oligorecurrence, and oligoprogression. A maximum of three metastatic sites, all resectable or amenable to stereotactic therapy, was proposed as the definition of OMBC. Pelvic lymph nodes represented the only "organ" not included in the definition of OMBC. For staging, no consensus on the role of 18F-fluorodeoxyglucose positron emission tomography/computed tomography was reached. A favourable response to systemic treatment was proposed as the criterion for selection of patients for metastasis-directed therapy. CONCLUSIONS: A consensus statement on the definition and staging of OMBC has been formulated. This statement will help to standardise inclusion criteria in future trials, potentiate research on aspects of OMBC for which consensus was not achieved, and hopefully will lead to the development of guidelines on optimal management of OMBC. PATIENT SUMMARY: As an intermediate state between localised cancer and disease with extensive metastasis, oligometastatic bladder cancer (OMBC) might benefit from a combination of systemic treatment and local therapy. We report the first consensus statements on OMBC drawn up by an international expert group. These statements can provide a basis for standardisation of future research, which will lead to high-quality evidence in the field.

Upper tract urothelial carcinoma (UTUC) accounts for 10% of urothelial carcinomas (UCs) and has a substantial hereditary component. However, the majority of our knowledge of germline spectrum comes from bladder cancer (BCa) data in White populations. Here, we sequence 309 Chinese UTUC cases and identify 71 germline pathogenic/likely pathogenic (P/LP) mutations in 62 patients (20.1%). Compared with White cases, we observe disparities and similarities in inherited mutational profiles. Association analysis reveals that germline P/LP mutations in MSH2, BRCA2, BRCA1, and BRIP1 significantly increase UTUC risk in Chinese populations. Furthermore, germline P/LP mutation in homologous recombination genes indicates poor prognosis for non-metastatic UTUC. Finally, we perform paired sequencing and observe significant correlations between germline mutation patterns and tumor subtypes. This study highlights the importance of genetic testing in patients with UTUC and calls for germline data from various ethnicities to better understand this disease.
