目的 分析临床T2N0M0胸上中段食管癌后程加速超分割放射治疗的疗效、副反应及失败原因。方法 回顾分析后程加速超分割放射治疗临床分期T2N0M0胸上、中段食管鳞癌 5 3例 ,放射方法均为前 2 / 3疗程常规放疗 ,每次 1.8Gy,共 41.4Gy左右 ;后 1/ 3疗程缩野改为加速超分割放射治疗 ,每天 2次 ,1.5Gy/次 ,共 2 7Gy左右。全疗程 40～ 49d ,总剂量为 6 7～ 70Gy/ 40～ 43Fx。结果5 3例患者 1,2 ,5年生存率分别为 89.9%、6 6 .8%和 5 1.2 % ;1,2 ,5年局控率分别为 92 .1%、87.1%和87.1%。死亡 17例 ,其中死于未控和局部复发 5例 ,占 2 9.4% ;远处转移 9例 (含 2例伴有淋巴结转移 ) ,占 5 2 .9% ;淋巴结转移 5例 (含 2例伴有远处转移 ) ,占 2 9.4% ;食管出血 1例 ,占 5 .9%。多因素分析显示 ,病变部位是其独立的预后因素 ,胸上段优于胸中段。结论 后程加速超分割放射治疗可作为治疗胸上、中段早期食管鳞癌的首选方法之一。
Objective To analyse the result of late course accelerated hyper-fractionated radiotherapy (LCAHFR) of upper and middle thoracic segment esophageal T2N0M0 carcinoma. Methods Fifty-three patients with squamous cell esophageal T2N0M0 carcinoma in the upper and middle segment were treated by LCAHFR from August 1994 to January 2000. The design of the radiation fields were based on CT and barium examination. All patients were treated with the conventional fractionated radiotherapy during the first two-thirds of the treatment to a dose about 41.4 Gy/23 F/4 to 5 weeks. This was followed by accelerated hyper-fractionated irradiation using reduced fields, twice daily at 1.5 Gy per fraction to a dose about 27 Gy/18 d. Thus, the total dose was 67～70 Gy/40～43 F/40～49 d.Results The 1-, 2- and 5-year actuarial survival rates were 89.9%, 66.8% and 51.2%, respectively. The 1-, 2- and 5-year local control rates were 92.1%, 87.1% and 87.1%. Of the 17 patients who died, 5 died of local failure (29.4%), 9 (52.9%) of distant metastasis, 5 (29.4%) of lymph metastasis and 1 (5.9%) of bleeding from the esophagus. The Cox multivariate model showed that the site of lesion was the only prognostic factor, with upper better than the middle segment.Conclusion Late course accelerated hyper fractionated radiotherapy is one of the best radiation treatment regimen for early esophageal carcinoma in the upper and middle thoracic segment.
