     摘要: 目的: 评价中晚期食管癌术后放疗的临床价值。方法: 40例食管癌术后患者均采用医用电子直线加速器6 MVX线外照射进行治疗。用模拟机定位，设三野或四野，无肿瘤残留者肿瘤照射剂量为5 000 cGy，有肿瘤残留者肿瘤照射剂量为6 000~7 000 cGy。锁骨上淋巴结转移灶用6MVX线和9MeVE线的混合线束照射治疗，肿瘤照射剂量控制在6 000~7 000 cGy。结果: 40例患者中38例随访2~9年， 1、3、5年生存率分别为67.5%、34.3%、30.0%。死亡29例，死于局部复发3例(10.3%)，远处转移19例(65.5%)，其它疾病2例(6.9%)，原因不明5例(17.2%)。结论: 食管癌术后放疗能降低局部复发率，提高5年生存率，但不能降低远处转移率。

    Abstract: Objective: To evaluate the clinical effect of postoperative radiotherapy for advanced esophageal carcinoma. Methods: Forty patients with esophageal carcinoma after surgery were treated by using electronic line accelerator 6MVX line. Simutator was used for location. Three or four fields were planned. Patients without residual tumor were given 5 000 cGy and those with residual tumor were given 6 000 cGy~7 000 cGy. The 6MV X ray or 9Mev E ray were used for the supra clavicle lymph node metastatic focus and the tumor dose was controlled within 6 000 cGy~7 000 cGy. Results: Among 40 patients, 38 patients were followed up 2~9 year .the 1, 2, 3year survival rates were 67.5%, 34.3%, 30.0% respectively. Among 29 patients who had died, the causer of death 3 with local recurrence (10.3%), 19 of far metastasis(65.5%), 2 died of other diseases (6.9%), The reason for 5 patients′ death was not clear (17.2%). Conclusions: Radiotherapy about esophageal carcinoma after surgery can decrease partial recurrence rates and raise 5year survival rates, but metastasis rates can not be decreased. ......
