Surgical management for small cell carcinoma of the esophagus

Abstract

Esophageal small cell carcinoma (SmCC) has been regarded as a rare and aggressive tumor with early metastasis. The optimal treatment has not yet been established, and the role of surgery has remained controversial. In this retrospective study, we report seven cases studies of SmCC of the esophagus and analyze the clinical outcomes after surgery. Between 1986 and 2007, there were seven patients with esophageal SmCC treated surgically in our institution. All the patients with clinically limited disease underwent transthoracic esophagectomy with lymphadenectomy. Lymph node involvement was found in all cases irrespective of the depth of tumor invasion. Three of the seven patients were diagnosed as having an extensive disease on pathological examination after esophagectomy. Five patients received postoperative chemotherapy. Two patients are alive with no recurrence at 16 months and at 45 months after surgery. Another one without chemotherapy survived 93 months and died of another disease. The remaining four patients died of recurrent disease or another disease. The median overall survival to date of these patients was 16 months (range 12-93 months). Esophagectomy with lymphadenectomy resulted in a relatively better survival in some patients with esophageal SmCC. We concluded that surgery may be helpful as part of multimodality treatment in selected patients with esophageal SmCC. © 2010 Copyright the Authors.
