摘要
本文总结^(60)钴放射治疗食管癌102例,一三、五年生存率分别为30.4％、10.8％、7.8％。影响预后的因素同病变部位、病变长度、照射剂量、转移有关。提出选择剂量以6000～6900ccy为好。放射治疗失败的主要原因是局未控与复发,因此,控制原发灶仍是食管癌放射治疗主要关键。
102 cases of esophageal carcinoma treated with ^(60)Co radiotherapy were reported.Of these cases. The 1-, 3-, 5-year survival rates were 30. 4%, 10. 8%, 7. 8%.Respecti-vely, and which was related to the location, and length of lesion, dosage ofirradiation and whether had distant metastasis or not. The results suggested that thebest choice for the dosage night be 6000～6900 CGy. The reason for failure of radiotherapy was chiefly due to in effective control and recurrence of Cocal lesion. Therefore, the key to the radiotherapy of esophaggeal carcinoma is to control theprotopathic focus effectively.
