    Abstract:
    OBJECTIVES: The aim of this study was to evaluate the feasibility, toxicity, and efficacy of a curative combination of chemo-radiotherapy with high-dose-rate brachytherapy (HDRB) in patients with non metastatic esophageal cancer. PATIENTS AND METHODS: Fifty-two patients with esophageal carcinoma were treated with > 50 Gy external irradiation, concomitant chemotherapy (5FU-CDDP) followed by HDRB delivering 12.5 Gy (6-20) as a boost. Twelve patients were stage I, 20 stage IIa, 5 stage IIb, and 13 stage III, 1 Tis, 1 stage N unknown. Surgery was not indicated for medical reasons. RESULTS: The response rate was 96%, with complete response rate 85%. The 1-, 3-, 5-year overall survival rates were 78%, 33%, and 22% respectively. A local failure occurred in 32%, and distant metastasis in 16%. Severe (grade 3, 4) acute toxicity occurred in 6 cases, severe late toxicity in 2 cases and there was 1 toxic death. Tumoral length > or = 5 cm and stage IIa, IIb and III versus stage 1 indicated poor prognosis. CONCLUSION: This regimen is feasible and well tolerated. The 5-year overall survival is 22%, but the local failure rate is still very high. These results are encouraging and will be prospectively evaluated with currently ongoing randomized trial.
