AIM： To compare the efficacy and toxicity of a three-step combination therapy with post-operative radiation alone for locally advanced esophageal cancer.METHODS： Patients with T3-4 and N0-1 esophageal carcinoma from a number of institutions were non-randomly, prospectively enrolled in the study. All patients underwent single-stage curative en bloc esophagectomy. The patients were then assigned into one of two treatment groups based on treatment consisting of either post-operative concurrent chemoradiotherapy （CCRT） with weekly cisplatin 30 mg/m^2 followed by systemic adjuvant chemotherapy （four monthly cycles of cisplatin 20 mg/m^2 and 5-fluorouracil 1 000 mg/m^2 for five consecutive days）, or, post-operative radiation alone. The radiotherapy dose was 55-60 Gy for all patients. Primary end-point of this study was to assess the per-protocol patients＇ improvement of overall survival benefit. Secondary end-point was designed to evaluate both the per-protocol and intent-totreat patients＇ outcome of survival. RESULTS： A total of 60 patients （n=30 per group） were enrolled in this study. The two groups were generally comparable for demographic characteristics and hematological and non-hematological toxicities. The CCRT with weekly cisplatin was well tolerated, with significantly better overall survival （30.9 mo vs 20.7 mo; 95% CI, 27.5-36.4 vs 15.2-26.1） and 3-year survival （70.0% vs 33.7%; P=0.003）. Low histological grade of tumor （P〈0.001） was associated with favorable survival in these locally advanced patients. CONCLUSION： For locally advanced esophageal cancer, the combination of esophagectomy, post-operative CCRT with weekly cisplatin and systemic adjuvant chemotherapy is well tolerated and effective. A large-scale, prospective randomized trial of this regimen is in progress.
