Clinicopathological factors in bladder cancer for cancer-specific survival outcomes following radical cystectomy: a systematic review and meta-analysis.

ABSTRACT:

Background

Assessing the prognostic significance of specific clinicopathological features plays an important role in surgical management after radical cystectomy. This study investigated the association between ten clinicopathological characteristics and cancer-specific survival (CSS) in patients with bladder cancer.

Methods

In accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines, a literature search was conducted through the PubMed, EMBASE and Web of Science databases using appropriate search terms from the dates of inception until November 2018. Pooled hazard ratios (HRs) with 95% confidence intervals (CIs) were calculated to evaluate the CSS. Fixed- or random-effects models were constructed according to existence of heterogeneity.

Results

Thirty-three articles met the eligibility criteria for this systematic review, which included 19,702 patients. The overall results revealed that CSS was associated with advanced age (old vs. young: pooled HR?=?1.01; 95% CI:1.00-1.01; P?ConclusionsOur results revealed that several clinicopathological characteristics can predict CSS risk after radical cystectomy. Prospective studies are needed to further confirm the predictive value of these variables for the prognosis of bladder cancer patients after radical cystectomy.

Project description:Introduction and objectiveMuscle invasive bladder cancer with extravesical extension is an aggressive disease entity that requires multimodal therapy. The benefits of adjuvant chemotherapy (AC) in patients with a positive soft-tissue surgical margin (STSM), however, are relatively unknown due to exclusion of this population in randomized controlled trials of AC. We sought to define survival benefits in this patient population through our institutional bladder cancer database.MethodsRetrospective review of all patients undergoing radical cystectomy for urothelial carcinoma of the bladder from 2004-2020 with ≥pT3b disease irrespective of neoadjuvant chemotherapy (NAC) use was conducted. Progression-free survival (PFS) and overall survival (OS) estimates were obtained using the Kaplan-Meier method with log-rank test, and the Cox-proportional hazards model was used to identify predictors of improved PFS and OS. AC was defined by any chemotherapy use within 90 days of cystectomy, regardless of STSM status.Results476 patients with pT3b disease or worse were identified. Median follow-up was 12.3 months. An amount of 21% of patients were treated with AC. An amount of 24% of patients had positive STSM. Median OS for patients with positive STSM was 8.4 months [95% CI 7-11.5] and 18.3 months [95% CI 15.6-20.8] (p < 0.001) for patients with negative STSM. In the overall cohort, positive STSM (HR 1.93, 95% CI 1.45-2.57, p < 0.001), AC use (HR 0.68, 95% CI 0.51-0.90, p = 0.007), and pN1-3 disease (HR 1.47, 95% CI 1.16-1.87, p = 0.002) were independent predictors of OS when adjusted for performance status, pT-stage, and neoadjuvant chemotherapy use. In patients with positive STSM, median survival was seven months [95% CI 5.2-8.4] without AC, compared to 16.2 months [95% CI 11.5-52.5] with AC (p = 0.0038). For patients with negative STSM, median survival was 17.4 months [95% CI 14-20.1] without AC compared to 22.3 months [95% CI 17.2-36.9] with AC (p = 0.23). In patients with positive STSM, AC use was the only factor associated with an OS benefit with a HR of 0.41 (95% CI 0.21-0.78, p = 0.007). In patients with negative STSM, pT4 and pN1-3 disease were the only factors associated with worse overall survival with a HR of 1.32 (95% CI 1.00-1.74, p = 0.050) and 1.97 (95% CI 1.49-2.60, p < 0.001), respectively.ConclusionsAdministration of adjuvant chemotherapy is of particular benefit in patients with positive STSM following radical cystectomy for gross extravesical disease. Positive STSM may be a representative of "early metastatic" or micrometastatic disease.
