【摘要】 <正> 医用加速器在放射剂量方面有许多优点,但在临床实际应用中究竟能否提高生存率是众所关心的问题。本文对我院1982年10月至1984年6月住院100例食管癌患者应用直线加速器10MV-X线治疗（10MV-X组）,并与同期用远距离⁶⁰Co治疗的100例食管癌(⁶⁰Co组)作回顾性对比分析如下:更多还原

【Abstract】 From 1982 to 1984, 100 patients with carcinoma of esophagus were treated by linear-accelerator do MV-X) (Linear group) and 100 patients were treated by telecobalt (60Co group) during the same period. To compare their validity, the results showed that the, 1,3 and 5 year survival rates were 56%, 22% and 12% in the linear group, and 52%, 15% and 10% in the 60Co group. There is no statistical significance in the difference between these two groups (p>0.05). The main cause of death in both groups was local recurrence or uncontrol. But the radiation reaction in the linear group was milder than that of the 60Co group, specially with the difference of early reactions more apparent (p<0.05).更多还原
