摘要
Abstract
Objective To investigate the significance and curative effect of three dimensional conformal radiation therapy (3D-CRT) in mediastinal lymph node metastasis after radical resection of esophageal carcinoma. Methods A retrospec-tive analysis was done by 45 patients with mediastinal lymph node metastasis after radical resection of esophageal carcinoma. They were treated by conventional fractionated SF-3DCRT, the GTV (gross tumor volume) prescription dose is 64 Gy and the CTV (clinical target volume) prescription dose is 50 Gy, CTV is 1~1.5 cm Outside the scope of GTV. No prophylactic irradiation in the other site which is not metastasis. Results CT examinations were taken after 3 months’radiotherapy. Ac-cording to RECIST(Response Evaluation Criteria in Solid Tumors), the total effective rate is 73.3%, the complete remission rate is 33.3%, the median survival time is 16.7 months, toxicity and side effect are not obvious. Conclusion 3DCRT is rec-ommended for the patients with Mediastinal Lymph Node Metastasis after Radical Resection of Esophageal Carcinoma.关键词
