During the period 1970 to 1987, 11 patients with small cell carcinoma of the esophagus were treated at Memorial Sloan-Kettering Cancer Center, New York. This rare tumor was responsible for 1.1% of all patients with esophageal tumors seen on the inpatient services during that period. Using a clinical staging system similar to that employed in small cell cancer of the lung, eight of 11 patients had extensive disease. Although responses were seen to multidrug combination chemotherapy regimens used alone or with sequential radiation, the overall prognosis for small cell esophageal cancer was poor, with a median survival of 7.5 months. Only one patient lived for greater than 2 years.
