Abstract

Objective: The aim of this study was to examine the epidemiology, natural history, treatment pattern and predictors of long-term survival of patients with signet-ring cell carcinoma (SRCC) of the urinary bladder based on the analysis of the national Surveillance, Epidemiology, and End Results (SEER) database. Methods and Results: In total, 230 patients with pathologically confirmed SRCC of the urinary bladder were identified between 1973 and 2004. The mean age was 65 ± 13 years. Overall, 75.7% of the patients had a poorly differentiated or undifferentiated histology grade, 26.5% presented with metastatic disease, 59 (25.7%) underwent transurethral resection for bladder tumor only and 107 (46.5%) had partial or radical cystectomy. The 1-, 3- and 10-year cancer-specific survival rates were 66.8, 40.6 and 25.8%, respectively. Using multivariable Cox proportional hazard model, age (HR 1.024; p = 0.004), stage (distant vs. local, HR 6.2; p < 0.001) and cystectomy (HR 0.53; p = 0.002) were identified as independent predictors for cancer-specific survival. Conclusions: Receipt of cystectomy was strongly associated with improved survival in the patients with SRCC of urinary bladder. However, many patients with localized tumors did not receive potentially curative cystectomy. Further studies to address the barriers to the delivery of appropriate care to these patients are warranted.
