食管癌术后颈胸部淋巴结转移者调强放疗效果分析

目的：观察三维适形调强放疗对食管癌根治术后颈胸淋巴结转移者的效果。方法：通过电话随访及电子病历回顾性分析54例食管鳞癌根治术后颈胸内淋巴结转移患者调强放疗的预后。用SPSS17统计软件分析影响预后的相关因素。结果：全组l、2、3年生存率为69％、55％、47％，中位生存时间29个月。胸部淋巴结转移患者中，淋巴结〈2cm者生存率优于1〉2cm者（矿=6．276，P：0．012），淋巴结转移的时间为生存率影响因素。结论：三维适形调强放疗治疗食管癌根治术后颈胸淋巴结转移疗效好，淋巴结转移时间是生存率影响因素，转移淋巴结大小是胸部转移患者生存率影响因素。

Effect of IMRT in patients with cervicothoracic lymph node metastasis after esophageal cancer surgery

Objective： To investigate the clinical effect of intensity modulated radiation therapy（IMRT） in the patients with cervicothoracic lymph node metastasis after esophageal cancer surgery. Methods： IMRT prognosis of the patients who accepted resection for esophageal squamous cell carcinoma and occurred cervicothoracic lymph node metastasis were evaluated through telephone interviews, and their electronic medical data. Prognostic factors were analyzed by SPSS 17. Results： 1,2,3-year survival rate of the whole group were 69% ,55% ,47%. The median survival time was 29 months. The patients with thoracic lymph node metastasis were stratified analyzed, patients with lymph nodes 〈2 cm had a higher survive rate than the patients with lymph nodes≥2 cm（x^2 = 6. 276, P =0. 012）. Duration of lymph node metastasis was the factor of survive rate. Conclusion： IMRT has a good effect on cervicothoracic lymph node metastasis after esophageal cancer surgery. Duration of lymph node metastasis is the factor of survive rate, the size of the metastatic lymph node is the factor of survive rate for the patients with thoracic lymph node metastasis.
