Objective To seek an effective and feasible treatment for esophageal carcinoma with unequal fractionation radiotherapy.Methods 160 patients with esophageal squamous carcinoma were randomized into an unequal frationation radiotherpy (UEFRT) group and a conventional fractionation radiotherapy (CFRT) group with 80 cases on each side. All the patients were simulated and irradiated by three port technique. Patients in the UEFRT group received D T70 Gy, at 4 Gy once daily, 5 days in the first week, then at 2 Gy daily, 5 days per week during the following five weeks. In the CFRT group,70 Gy was delivered with the routine regimen. Results The 5 year local control rates in UEFRT and CFRT groups were 46.3% and 27.5%(P
