PURPOSE: The present intergroup phase III randomized study compared combined chemotherapy (CT) plus radiotherapy (RT) treatment versus RT only in patients with locally advanced esophageal cancer. MATERIALS AND METHODS: Two courses of chemotherapy during 50 Gy RT followed by additional two courses of the same CT, versus 64 Gy RT alone were investigated. CT consisted of cisplatin 75 mg/m2 on day 1 [corrected] and fluorouracil (5FU) 1,000 mg/m2/d on days 1 to 4 every 4 weeks with RT and every 3 weeks post-RT. The main objective of the study was to compare overall survival between the two randomized treatment groups. Patients were stratified by tumor size, histology, and degree of weight loss. RESULTS:Sixty-two assessable patients were randomized to receive RT alone, and 61 to the combined arm. Patients characteristics were as follows: squamous cell cancer, 90% versus 85%; weight loss greater than 10 lb, 61% versus 69%; and tumor size, > or = 5 cm, 82% versus 80% on the RT and CT-RT arms, respectively. Systemic side effects, which consisted of nausea, vomiting, and renal and myelosuppression, occurred more frequently on the combined arm, while local side effects were similar in both groups. With a minimum follow-up time of 5 years for all patients, the median survival duration was 14.1 months and the 5-year survival rate was 27% in the combined treatment group, while the median survival duration was 9.3 months with no patients alive at 5 years in the RT-alone group (P < .0001). Additional patients (69) were treated with the same combined therapy and were analyzed. The results of the last group confirmed all of the results obtained with combined CT-RT in the randomized trial, with a median survival duration of 17.2 months and 3-year survival rate of 30%. CONCLUSION: We conclude that cisplatin and 5FU infusion given during and post-RT of 50 Gy is statistically superior to standard 64-Gy RT alone in patients with locally advanced esophageal cancer.
