Squamous cell carcinoma of the esophagus: a study of 153 cases

The incidence of esophageal carcinoma in the United States is relatively low; total estimated cases annually are about 7,000 (Ca, 1975). The overall cure rate, however, is about the worst among all malignant diseases and is reported to be 3% (Ca, 1975). We reviewed cases of squamous cell carcinoma of the esophagus treated at Roswell Park Memorial Institute to understand the clinicopathologic features in order to improve our therapeutic results.
