32 Background: Small cell carcinoma (SCC) of the esophagus is a rare aggressive and rapidly fatal neoplasm, often diagnosed in late stages. Hence no prospective studies evaluating the most effective treatment strategies have been done. We aim to describe the clinicopathological features and treatment outcomes of this rare entity. Methods: Retrospective analysis of 49 patients diagnosed with SCC of the esophagus from 1995 to 2009 was done via the Veteran's Affairs Central Cancer Registry. Demographics, staging, treatment, and outcomes data was recorded. Staging was classified as limited (no distant metastasis) or extensive stage (metastatic disease). Results: Out of 10,540 patients with esophageal cancer, 49 were diagnosed with SCC (0.005%) and were mainly located in the middle and lower thirds of the esophagus (84%). Median age of diagnosis was 64.1 yrs (range: 26-90). 19 patients had limited disease, 26 patients had extensive disease and four patients who were not staged adequately were excluded. Patients received a variety of treatments (Table) with different survival outcomes. Limited stage SCC patients had a median survival of 6.3 mos with patients who received combined modality therapy showing a trend towards improved outcomes. Extensive stage patients who received no therapy had very poor outcomes compared to patients who received any therapy. Conclusions: SCC of esophagus should be considered a systemic disease and like pulmonary SCC, it is an aggressive tumor associated with a poor prognosis. Patient numbers are too low to draw definitive conclusions regarding choice of therapy. Extensive disease patients benefit from chemotherapy and combined modality therapy should be considered in limited stage disease. [Table: see text]
