【Abstract】 From 1978 to 1985, 381 patients with esophageal cancer were treated by radiotherapy. 207 patients (54.3%) had lesions in the mid-thoraxic and 78 patients (20.5%) in the lower segment. 335 patients(87.2%)had lesions longer than 5 cm and 179 patients, over 7cm. All were treated by 3 or 4 fields technique and the tumor doses ranged from 40-80 Gy in 4-6 weeks. 89.5% of patients received more than 60 Gy by 22 MeV X-ray from betatron manufactured China. The over-all 1,3 and 5 year survival rates were 55.4%, 19.1% and 11.9%. Those treated with tumor dose more or less than 60 Gy gave 5 year suivivals of 12.9% and 5.9%.更多还原
