Conservative treatment of esophageal cancer with radiation therapy has afforded few long-term survivors. In order to improve outcome, patients with locoregional disease were treated using a combined modality approach. Patients were treated with chemotherapy consisting of a 96-hour continuous infusion of 5-fluorouracil (5-FU), 1,000 mg/m2/d, days 1 to 4 and days 29 to 32; cisplatin 75 mg/m2, day 1 and 29; and radiation 3,000 rad, days 1 to 19. In the absence of progressive disease, patients underwent esophagectomy. One hundred twenty-eight patients were registered of whom 113 were eligible and 106 were evaluable. Toxicity included gastrointestinal (GI) symptoms, mucositis, and myelosuppression. One hundred two patients completed chemoradiotherapy. Following its completion, 11 patients refused surgery, six were considered poor surgical risks, and 14 had progressive disease. Of the remaining 71 patients, 16 had unresectable disease, 13 had residual disease which was incompletely resected, 24 had disease which could be completely resected, and 18 were without disease on pathologic examination. The overall operability rate was 63% and the overall resectability rate, 49%. Surgical mortality was 11%. Eighty-nine of 113 eligible patients have died, with a median survival of 12 months and a 2-year survival of 28%. The median postsurgical survival for all 71 patients was 14 months and was 32 months for those patients attaining complete remission (CR). Combined modality therapy remains an investigational approach. Attempts should be directed at increasing response rate to initial therapy. A randomized comparison between combined modality treatment and radiation therapy is necessary to definitively determine the usefulness of this more aggressive approach.
