Description

BACKGROUND:Neuroendocrine carcinoma of the urinary bladder (NCUB) is rare, accounting for < 1% of bladder cancer cases, with scarce reported data available.MATERIALS AND METHODS:We retrospectively reviewed the data from patients with NCUB treated at French institutions. The objectives were to describe the patient characteristics, treatments received, and outcomes (ie, disease-free survival [DFS], progression-free survival, overall survival [OS]) and investigate the prognostic factors.RESULTS:From 1997 to 2017, we included 236 patients, 173 with early-stage NCUB and 63 with advanced-stage NCUB. For those with early-stage disease, the median DFS was better for the patients who had received cisplatin-based chemotherapy compared with carboplatin (hazard ratio [HR], 1.95; 95% confidence interval [CI], 1.1-3.46), with no difference found between the neoadjuvant and adjuvant settings (HR, 1.1; 95% CI, 0.61-1.97). The median OS was 36 months (95% CI, 29-43 months) for stage I and II, 26 months (95% CI, 18 months to not reached) for stage IIIA, 16 months (95% CI, 12-21 months) for stage IIIB. The HR for stage IIIB compared with stage I/II was 2.6 (95% CI, 1.5-4.4). The DFS at 6 months was associated with OS (HR, 7.8; 95% CI, 4.1-15.0). For patients with metastases at diagnosis who had received chemotherapy, the median progression-free survival was 9 months (95% CI, 8-11) for first-line cisplatin and 6 months (95% CI, 4-13 months) for carboplatin; the median OS was 13 months (95% CI, 9-15 months). A high-risk Bajorin score (HR, 11.5; 95% CI, 1.2-112.6) and the use of carboplatin (HR, 2.26; 95% CI, 1.03-4.96) were associated with worse outcomes.CONCLUSIONS:In early-stage disease, a shorter DFS was associated with worse OS, and the use of cisplatin was associated with better OS. For the patients with metastases at diagnosis, a high-risk Bajorin score and the use of carboplatin were associated with worse outcomes.
