Pathologic and survival outcomes following radical cystectomy for "progressive" and "de novo" muscle-invasive bladder cancer: A meta-analysis stratified by neoadjuvant chemotherapy status. Urol Oncol 2024; 42:333.e1-333.e13. [PMID: 38697874 DOI: 10.1016/j.urolonc.2024.04.020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2024] [Revised: 04/10/2024] [Accepted: 04/18/2024] [Indexed: 05/05/2024]
Abstract
OBJECTIVE To compare survival and pathologic outcomes in patients with progressive muscle-invasive bladder cancer (pgMIBC) and de novo muscle-invasive bladder cancer (dnMIBC) after radical cystectomy (RC), with a focus on the role of neoadjuvant chemotherapy (NAC). METHODS A comprehensive literature search was conducted on PubMed and EMBASE databases to identify studies comparing pgMIBC to dnMIBC. Survival outcomes, including cancer-specific survival (CSS), overall survival (OS), and recurrence-free survival (RFS), and pathologic outcomes (rates of ≤pT1, pT0, pT3/T4, and pN+ disease) were compared between pgMIBC and dnMIBC. RESULTS The analysis included 19 cohorts from 16 studies, categorized into 3 groups based on NAC use: 1. patients who underwent RC and were all treated with NAC (RC + NAC only group); 2. patients who underwent RC, with or without NAC (RC +/- NAC group); 3. patients who only underwent RC without NAC (RC only group). Compared to dnMIBC, pgMIBC demonstrated worse outcomes for CSS, OS, and RFS. In the RC + NAC only group (3 cohorts), the hazard ratio (HR) for CSS was 1.52 (95% confidence interval [CI] = 1.05-2.2), while the HR for OS was 1.46 (95%CI = 1.05-2.02). Similarly, in the RC +/- NAC group (6 cohorts for CSS and 3 cohorts for OS), the HR for CSS was 1.27 (95%CI = 1.05-1.55), and the HR for OS was 1.27 (95%CI = 1.08-1.51). There were no significant differences observed in pathologic outcomes, including rates of ≤pT1, pT0, and pT3/T4 disease, across all subgroups. However, pgMIBC was associated with a higher risk of nodal metastatic (pN+) disease in the RC + NAC only group (4 cohorts, relative risk [RR] = 1.43, 95%CI = 1.12-1.84). CONCLUSIONS The findings highlight the potentially worse prognosis in patients with pgMIBC compared to dnMIBC, even with the modern use of NAC. The study emphasizes the importance of careful patient counseling, further classification of patients for treatment selection, and the consideration of additional or innovative systemic therapies for pgMIBC.

Nat Rev Urol 2024:10.1038/s41585-024-00914-7. [PMID: 39095581 DOI: 10.1038/s41585-024-00914-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 06/21/2024] [Indexed: 08/04/2024]
Abstract
The global incidence of bladder cancer is more than half a million diagnoses each year. Bladder cancer can be categorized into non-muscle-invasive bladder cancer (NMIBC), which accounts for ~75% of diagnoses, and muscle-invasive bladder cancer (MIBC). Up to 45% of patients with NMIBC develop disease progression to MIBC, which is associated with a poor outcome, highlighting a clinical need to identify these patients. Current risk stratification has a prognostic value, but relies solely on clinicopathological parameters that might not fully capture the complexity of disease progression. Molecular research has led to identification of multiple crucial players involved in NMIBC progression. Identified biomarkers of progression are related to cell cycle, MAPK pathways, apoptosis, tumour microenvironment, chromatin stability and DNA-damage response. However, none of these biomarkers has been prospectively validated. Reported gene signatures of progression do not improve NMIBC risk stratification. Molecular subtypes of NMIBC have improved our understanding of NMIBC progression, but these subtypes are currently unsuitable for clinical implementation owing to a lack of prospective validation, limited predictive value as a result of intratumour subtype heterogeneity, technical challenges, costs and turnaround time. Future steps include the development of consensus molecular NMIBC subtypes that might improve conventional clinicopathological risk stratification. Prospective implementation studies of biomarkers and the design of biomarker-guided clinical trials are required for the integration of molecular biomarkers into clinical practice.

Prognostic variations between 'primary' and 'progressive' muscle-invasive bladder cancer following radical cystectomy: a novel propensity score-based multicenter cohort study. Int J Surg 2024; 110:270-279. [PMID: 37738002 PMCID: PMC10793809 DOI: 10.1097/js9.0000000000000790] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2023] [Accepted: 09/10/2023] [Indexed: 09/23/2023]
Abstract
OBJECTIVE To assess prognostic differences between primary and progressive muscle-invasive bladder cancer (MIBC) following radical cystectomy. MATERIAL AND METHODS The Surveillance, Epidemiology, and End Results (SEER) database was used to abstract MIBC data following radical cystectomy from 2000 to 2019. Patients were classified as either 'Primary' MIBC (defined as the presentation of muscle-invasive disease at initial diagnosis) or 'Progressive' MIBC (defined as a non-muscle invasive disease that later progressed to MIBC). Baseline characteristics for the two groups were balanced using a propensity score overlap weight (PSOW) technique. Survival differences between the two groups were analyzed using Kaplan-Meier's plots and log-rank tests. Cox's proportional hazard regression was used to assess risk factors associated with overall survival (OS) and cancer-specific survival (CSS). RESULTS Six thousand six hundred thirty-two MIBC patients were identified in the SEER database. Among them, 83.3% ( n =5658) were considered primary MIBC patients, and 16.7% ( n =974) were categorized as progressive MIBC patients. Distribution of baseline covariates, including age, sex, race, T stage, N stage, tumour grade, marital status, and chemotherapy, were well-balanced after PSOWs were applied. After stable PSOW adjustments, Kaplan-Meier survival analysis showed that the CSS for progressive MIBC [hazard ratio (HR)=1.25, 95% confidence interval (CI): 1.12-1.38, P <0.001) was poorer than the primary MIBC group. However, the difference in OS (HR=1.08, 95% CI: 0.99-1.18) was not significant ( P =0.073). Multivariate analysis also suggested that patients with progressive MIBC have significantly poorer CSS (HR=1.24, 95% CI: 1.19-1.38, P <0.001) but not OS (HR=1.08, 95% CI: 0.99-1.18, P =0.089). CONCLUSION CSS for progressive MIBC patients appears worse than for those with primary MIBC. This highlights the need to direct more resources for this patient population and particularly for high-risk cases of non-MIBC, where timely radical surgery will improve patients prognoses.

Abstract
BACKGROUND Urothelial carcinoma is a major subtype of bladder cancer and small cell carcinoma (SCC) is a rare type of cancer in clinical practice. Pathologic collision of urinary bladder urothelial carcinoma with SCC is not common in clinical settings. CASE PRESENTATION Here, we report a patient with high-grade papillary carcinoma which changed to collision tumor with SCC. The patient underwent radical cystectomy; however, neck and mediastinum lymph nodes metastases were detected 11 months after the operation. The lymph nodes were diagnosed pathologically as SCC. Chemoradiotherapy was subsequently prescribed. Unfortunately, this patient died of COVID-19 in early 2023. DISCUSSION We hypothesized the mechanism underlying this pathological transformation. For patients with urothelial bladder cancer, pathological analysis should be conducted to allow standardized and persistent treatment. Moreover, drugs should be selected depending on the type of pathology, especially for patients who develop relapse, since collision tumor or other pathological tumors may be present. CONCLUSIONS We recommend that radical cystectomy be performed early enough for patients with non-muscle invasive bladder cancer, who are at a high risk of tumor recurrence. However, this conclusion needs to be validated in a larger number of patients.

Patient Preferences for Treatment of Bacillus Calmette-Guérin-unresponsive Non-muscle-invasive Bladder Cancer: A Cross-country Choice Experiment. EUR UROL SUPPL 2023; 49:92-99.

Abstract
Background Patients with non-muscle-invasive bladder cancer (NMIBC) that is unresponsive to bacillus Calmette-Guérin (BCG) immunotherapy face a difficult choice. Immediate radical cystectomy (RC) is effective but might represent overtreatment. Continuing bladder preservation with medical therapy is an alternative, but it risks progression to muscle-invasive bladder cancer (MIBC) and a reduction in survival. Objective To understand the trade-offs patients are willing to make in selecting treatments for BCG-unresponsive NMIBC. Design setting and participants Adults with NMIBC from the UK, France, Germany, and Canada who reported current receipt of BCG, disease unresponsive to BCG, or receipt of RC in the previous 12 mo after failure of BCG were recruited to participate in an online choice experiment. Patients were asked to make repeated choices between two hypothetical medical treatments and the option to undergo immediate RC. The medical treatments required trade-offs between the time to RC, the mode and frequency of administration, the risk of experiencing serious side effects, and the risk of disease progression. Outcome measurements and statistical analysis Error component logit models were used to calculate relative attribute importance (RAI) scores as the maximum percentage contribution to a preference and acceptable benefit-risk trade-offs. Results and limitations Most of the 107 participants (average age 63 yr) never selected RC (89%) as their preferred option in the choice experiment. Preferences were most affected by time to RC (RAI 55%), followed by risk of progressing to MIBC (RAI 25%), medication administration (RAI 12%), and the risk of serious side effects (RAI 8%). To increase the time to RC from 1 yr to 6 yr, patients accepted a 43.8% increase in the risk of progression and a 66.1% increase in the risk of serious side effects. Conclusions Patients with BCG-treated NMIBC valued bladder-sparing treatments and were willing to make substantial benefit-risk trade-offs to delay RC. Patient summary Adults with bladder cancer not invading the bladder muscle completed an online experiment in which they chose between hypothetical medications and bladder removal. The results show that patients would be willing to accept different risks associated with medications to delay bladder removal. Patients considered disease progression the most important risk of medicinal treatment.

Abstract
OBJECTIVE To update the ccAFU recommendations for the management of bladder tumours that do not infiltrate the bladder muscle (NBMIC). METHODS A systematic review (Medline) of the literature from 2020 to 2022 was performed, taking account of the diagnosis, treatment options and surveillance of NMIBC, while evaluating the references with their levels of evidence. RESULTS The diagnosis of NMIBC (Ta, T1, CIS) is made after complete full-thickness tumour resection. The use of bladder fluorescence and the indication of a second look (4-6 weeks) help to improve the initial diagnosis. The EORTC score is used to assess the risk of recurrence and/or tumour progression. Through the stratification of patients in low, intermediate and high-risk categories, adjuvant treatment can be proposed: intravesical chemotherapy (immediate postoperative, initiation regimen) or BCG (initiation and maintenance regimen) instillations, or even the indication of cystectomy for BCG-resistant patients. CONCLUSION Updating the ccAFU recommendations should contribute to improving patient management, as well as the diagnosis and treatment of NMIBC.

Abstract
PURPOSE To assess if cancer-specific survival (CSS) following curative intent treatment (CIT) for muscle-invasive bladder cancer (MIBC) differs between patients presenting with MIBC (primary) and patients presenting with non-muscle-invasive bladder cancer who progress to MIBC (secondary). METHODS This study uses data from the Cancer Registry of Norway on patients initially diagnosed with bladder cancer in 2008-2012 and treated with radical cystectomy (RC) or radiotherapy (RT). To ensure a clinically relevant population, we selected patients with a pre-treatment histology confirming muscle-invasion. Survival models were applied to evaluate differences in observed and adjusted CSS by type of MIBC and stratified by type of CIT. Adjustment was made for age group, sex, previous cancer, diagnostic hospital's academic status and geographical region, and type of CIT. RESULTS We identified 650 eligible patients: 589 (91%) primary MIBC and 61 (9%) secondary MIBC. A total of 556 (86%) patients underwent RC and 94 (14%) RT. The 5-year CSS for primary MIBC was 56% and 59% for secondary MIBC (p = 0.68). The type of MIBC did not impact the risk of bladder cancer death (HR = 0.85, CI = 0.55-1.33, p = 0.48), nor when stratified for CIT (RC: HR = 0.93, CI = 0.57-1.53, p = 0.78); RT: HR = 0.71, CI = 0.24-2.16, p = 0.55). CONCLUSION This first nation-wide population-based study comparing CSS between primary and secondary MIBC showed no significant difference in survival regardless of type of CIT. Continued surveillance of patients with non-muscle-invasive bladder cancer is necessary to detect early progression to MIBC. Future studies should include molecular and genetic characteristics in addition to detailed clinicopathologic information.

Comparative Outcomes of Primary Versus Recurrent High-risk Non–muscle-invasive and Primary Versus Secondary Muscle-invasive Bladder Cancer After Radical Cystectomy: Results from a Retrospective Multicenter Study. EUR UROL SUPPL 2022; 39:14-21.

Abstract
Background Radical cystectomy (RC) is indicated in primary or secondary muscle-invasive bladder cancer (primMIBC, secMIBC) and in primary or recurrent high- or very high-risk non–muscle-invasive bladder cancer (primHR-NMIBC, recHR-NMIBC). The optimal timing for RC along the disease spectrum of nonmetastatic urothelial carcinoma remains unclear. Objective To compare outcomes after RC between patients with primHR-NMIBC, recHR-NMIBC, primMIBC, and secMIBC. Design, setting, and participants This retrospective, multicenter study included patients with clinically nonmetastatic bladder cancer (BC) treated with RC. Outcome measurements and statistical analysis We assessed oncological outcomes for patients who underwent RC according to the natural history of their BC. primHR-NMIBC and primMIBC were defined as no prior history of BC, and recHR-NMIBC and secMIBC as previously treated NMIBC that recurred or progressed to MIBC, respectively. Log-rank analysis was used to compare survival outcomes, and univariable and multivariable Cox and logistic regression analyses were used to identify predictors for survival. Results and limitations Among the 908 patients included, 211 (23%) had primHR-NMIBC, 125 (14%) had recHR-NMIBC, 404 (44%) had primMIBC, and 168 (19%) had secMIBC. Lymph node involvement and pathological upstaging were more frequent in the secMIBC group than in the other groups (p < 0.001). The median follow-up was 37 mo. The 5-year recurrence-free survival (RFS), cancer-specific survival (CSS), and overall survival (OS) were 77.9%, 83.2%, and 72.7% in primHR-NMIBC, 60.0%, 59%, and 48.9% in recHR-NMIBC, 60.9%, 64.5%, and 54.8% in primMIBC, and 41.3%, 46.5%, and 39% in secMIBC, respectively, with statistically significant differences across all survival outcomes except between recHR-NMIBC and primMIBC. On multivariable Cox regression, recHR-NMIBC was independently associated with shorter RFS (hazard ratio [HR] 1.64; p = 0.03), CSS (HR 1.79; p = 0.01), and OS (HR 1.45; p = 0.03), and secMIBC was associated with shorter CSS (HR 1.77; p = 0.01) and OS (HR 1.57; p = 0.006). Limitations include the biases inherent to the retrospective study design. Conclusions Patients with recHR-NMIBC and primHR-MIBC had similar survival outcomes, while those with sec-MIBC had the worst outcomes. Therefore, early radical intervention may be indicated in selected patients, and potentially neoadjuvant systemic therapies in some patients with recHR-NMIBC. Patient summary We compared cancer outcomes in different bladder cancer scenarios in a large, multinational series of patients who underwent removal of the bladder with curative intent. We found that patients who experienced recurrence of non–muscle-invasive bladder cancer (NMIBC) had similar survival outcomes to those with initial muscle-invasive bladder cancer (MIBC), while patients who experienced progression of NMIBC to MIBC had the worst outcomes. Selected patients with non–muscle-invasive disease may benefit from early radical surgery or from perioperative chemotherapy or immunotherapy.

Abstract
Introduction Muscle invasive bladder cancer (MIBC) is a common malignancy amongst elderly. Increasing life expectancy, prevalence of smoking, lifelong exposure to environmental pollutants and immunosenescence contribute to growing number of cases. Traditionally, radical cystectomy (RC) with pelvic lymph node dissection (PLND) constituted the mainstay of treatment for MIBC, but despite proven feasibility in elderly population, it has been associated with significant burden of morbidity, mortality, and complications. Study Objective We aimed to re-evaluate the safety and efficacy of RC amongst the elderly patients with MIBC. Material and Methods This single-center, retrospective, observational comparative study was conducted among 568 patients who underwent RC due to MIBC between 2003 and 2021. We evaluated the influence of chronological age (<70 vs ≥70 years) on clinical, demographic, and pathological variables related to MIBC and RC. Results Elderly patients had similar clinical and pathological features of disease compared to their younger counterparts; nonetheless, they more often received simplified urinary diversion, ie ureterostomy (60.25% vs 39.33%, p<0.001) and had no PLND (15.76% vs 8.5%, p=0.01) during RC. Furthermore, more elderly patients were treated for secondary MIBCs and fewer had history of smoking. Severe complication and 90-day mortality rates were comparable between groups; however, the elderly had significantly higher all-cause mortality at one year post RC (46.67% vs 33.25%, p=0.003). On multivariate analysis, one-year mortality risk was independently associated with elderly age (HR=2.119, 95% CI: 1.227–3.660, p=0.007), rural residency (HR=1.760, 95% CI: 1.043–2.968, p=0.034), extravesical extension of tumor (HR=2.109, 95% CI: 1.155–3.850, p=0.015), lymph node metastasis (HR=2.268, 95% CI: 1.290–3.987, p=0.004) and omission of PLND (HR=6.064, 95% CI: 2.926–12.568, p<0.001). Conclusion Radical cystectomy in elderly patients is associated with significant one-year mortality. Our study emphasizes the unmet need for considerate planning of treatment for MIBC in potentially vulnerable groups of elderly patients. Efforts are needed to reliably identify those unlikely to benefit from surgery and facilitate patient-centered choice of alternative therapies.
