title: Small cell carcinoma of the bladder. Report of five cases with immunohistochemistry and review of the literature with evaluation of prognosis according to stage.
abstract: Five cases of small cell carcinoma (SCC) of the bladder are reported with pathologic and immunohistochemical findings and clinical follow-up. Sixteen additional cases reported in the literature are studied and staged according to depth of tumor infiltration of the bladder wall. In our series of five cases and those reviewed from the literature, survival appeared to be dependent on stage of the tumor, analogous to the more common transitional cell carcinoma (TCC). We report two of five patients with the longest recorded follow-up times in the literature who are alive with no evidence of disease at 4 and 6 years. Contrary to the belief that SCC of the bladder is an aggressive, rapidly disseminating tumor similar to SCC of the lung, our findings support the notion that this is a potentially curable neoplasm with a prognosis that appears to be dependent on stage and surgical resectability.
