Small-cell carcinoma of the esophagus and gastroesophageal junction: review of the Memorial Sloan-Kettering experience.

Background: Esophageal small-cell carcinoma (SCC) is rare, highly malignant and the optimal treatment approach has not been defined.

Patients And Methods: We report the largest single-institution retrospective review of patients with esophageal and gastroesophageal (GE) junction SCC.

Results: Twenty-five patients were identified, with complete records available for 22. Eighty-two percent were male, 82% had pure SCC histology and 86% of tumors were in the lower esophagus or GE junction. On the basis of the Veterans' Administration Lung Study Group criteria, 14 patients (64%) presented with limited disease (LD). Median survival was 19.8 months (range, 1.5 months to 11.2+ years); for LD patients, 22.3 months (range, 6 months to 11.2+ years); for extensive disease (ED) patients, 8.5 months (range, 1.5 months to 2.2 years, P = 0.02). With a median follow-up of 38 months, six patients (27%) are alive, one with ED and five with LD. Two LD patients are alive and free of disease for >5 years. Four of the five LD patients who are long-term survivors received induction chemotherapy followed by chemoradiotherapy without surgery.

Conclusions: Our data indicate that patients with LD esophageal SCC treated with induction chemotherapy followed by consolidative chemoradiation can achieve long-term survival. The contribution of surgery remains unclear.
