Postoperative radiotherapy for carcinoma of the esophagus: a prospective, randomized controlled study.

Abstract

The shorter survival of patients who underwent postoperative radiotherapy was the result of irradiation-related death and the early appearance of metastatic diseases. The role of postoperative radiotherapy is therefore limited to a specific group of patients with residual tumor in the mediastinum after operation, for whom radiotherapy can significantly reduce the incidence of local recurrence obstructing the tracheobronchial tree.
