From March 1992 to May 1994, 105 patients with esophageal carcinoma patients were treated with CF/5-Fu-DDP (group A, n = 40) or 5-Fu-DDP (group B, n = 65) protocol. The response rate (CR+PR) was 80% in group A and 60% in group B. (P < 0.01) Induction chemotherapy was followed by surgery or radiation therapy. The incidence of nausea, vomiting, cardiotoxicity and leukopenina was higher in group A than in group B. Buccal mucositis, diarrhea, abdomenal pain and skin pigmentation were noted only in group A. However, the toxic effects were tolerable. The results suggest that the CF/5-Fu-DDP regimen is more effective than 5-Fu-DDP regimen and may be one of the best chemotherapy regimens for the treatment of esophageal carcinoma.
