目的 探讨胸段食管癌根治术后纵隔转移灶放射治疗的意义和效果。方法 回顾性分析 76例食管癌根治术后 3～ 18个月发生纵隔转移患者。转移灶 <2cm 11例 ,2～ 3cm 33例 ,>3cm 32例。伴有颈淋巴结转移 9例 ,伴脏器转移 3例。放射治疗采用60 Co常规分割照射 ,照射剂量10 .8～ 75 .0Gy。结果 未完成治疗计划的 9例患者均于照射后 1年内死亡。照射剂量为 5 0～ 75Gy患者 1、2、3年生存率分别为 75 .0 % (5 7/ 76 )、2 7.6 % (2 1/ 76 )和 9.2 % (7/ 76 )。结论 食管癌根治术后发生纵隔转移进行放射治疗可以延长患者生存时间 ,照射剂量以组织量 6 5～ 75Gy为宜
Objective To investigate the significance and effect of radiotherapy for mediastinal metastases after thoracic esophagectomy. Methods A retrospective analysis of 76 cases of esophageal cancer occurred 3 to 18 months after radical mediastinal metastasis. 11 cases of metastasis <2cm, 33 cases of 2 ~ 3cm, 32 cases of> 3cm. Accompanied by cervical lymph node metastasis in 9 cases, accompanied by organ metastasis in 3 cases. Radiotherapy using 60 Co conventional split irradiation, irradiation dose of 10 .8 ~ 75 .0 Gy. Results Nine patients who did not complete the treatment plan died within 1 year after irradiation. The 1-, 2-, and 3-year survival rates were 75.0% (57/76), 7.6% (21/76) and 9.2% (7/76), respectively. Conclusion Radical therapy of mediastinal metastasis after radical operation of esophageal cancer can prolong the survival time of patients. The dose of irradiation should be 65-575 Gy
