A cooperative, prospective, randomized study to evaluate the effectiveness of preoperative irradiation in curatively resected esophageal carcinoma was performed in 364 cases in eight institutions from August 1982 to November, 1983. Based on the survival curves, postoperative irradiation alone was superior to preoperative plus postoperative irradiation. Because of the progression of the disease and complications after operation, there were many inevaluable cases in this study. However, analysis revealed there was no bias caused by a greater number of unfavorable patients being selectively included in inevaluable cases in the postoperative irradiation only group. Our data question the value of preoperative irradiation being performed in addition to resection plus postoperative irradiation.
