    Abstract:
    From October 1986 to January 1991, 47 patients with esophageal cancer (29 squamous, 18 adenocarcinoma) were treated with simultaneous radiotherapy (3000 or 3600 cGy) and chemotherapy (infusional 5-fluorouracil, cisplatin) delivered during a 5-week period. This treatment was well tolerated; 44 patients (94%) completed a full course of therapy, 40 (85%) had relief from dysphagia, and 21 (45%) noted either weight gain or no net weight loss. One patient (2%) died of complications (tracheoesophageal fistula, perforated ulcer) during chemotherapy and radiotherapy. The remaining 46 patients were referred for operation. Six refused because of excellent relief of their dysphagia, and one was denied operation. Thirty-nine patients went to operation, and 34 (83%) had lesions that were resectable. Eight of the 39 surgically treated patients (21%) had no evidence of residual tumor identified in the resected specimens. One of these complete responders died 7 weeks postoperatively after multiple complications (3% operative mortality rate). Three of the remaining seven have also died since the operation, one of recurrent cancer and two with no known recurrent disease. Actuarial survival in this present series was significantly better than that of our 1980 to 1985 historical control patients (p less than 0.005). There was no difference between patients with squamous carcinoma and those with adenocarcinoma with regard to the prevalence of complete response or long-term survival. Survival of the seven patients who did not undergo operation was comparable with that of the 34 patients in whom esophagectomy was performed. This study suggests that combined preoperative chemotherapy plus radiotherapy for esophageal cancer is well tolerated, provides excellent palliation of symptoms, allows for a high rate of resectability, is equally effective for squamous carcinoma and adenocarcinoma, and provides encouraging early results with regard to long-term survival. The data also call into question the role of esophagectomy, particularly in patients who have a complete response to preoperative therapy.
