摘要
目的 :探讨病灶长度 <5cm食管癌放射治疗的疗效及其特点。方法 :我科于 1994年 1月～ 1996年 12月收治食管癌病灶长度 <5cm的患者 13 8例 ,全部均行常规放射治疗 ,食管剂量为 60Gy～ 70Gy。结果 :全组 1、3、5年生存率分别是 68 1%、2 3 2 %、13 8% ,年龄、部位与预后关系不大 ,疗终X线影像改变明显好转者 (CR)与部分好转者 (PR)的 5年生存率分别是 2 0 9%、2 4% (P <0 0 5 ) ,有显著性差异。病灶长度≤ 3cm的髓质型患者与缩窄型患者的 5年生存率分别为 3 3 3 %、5 0 % (P <0 0 1)。结论 :小于 5cm长度的食管癌患者的放射治疗的预后 (CR或PR)与疗终X线影像改变关系密切 ;
Objective: To investigate the characteristics and radiotherapeutic results of those patients with esophageal carcinoma lesions less than 5cm in length.Methods:From 01/1994 to 12/1996,138 cases of esophageal carcinoma with lesions less than 5cm in length were treated in our hospital.All of them received the routine radiotherapy withD T of 60～70Gy.Results:1-?3-?5-year survival rates were 68.1%?23.2%?13.8%,respectively,ages and location of lesions had no evident relations to the prognosis;but X-ray image changes such as complete remission(CR) or partial remission(PR),had significant influence to the 5 year survival rates which reaches 20.9% for CR patients,but only 2.4% for those PR patients(P<0.05).5-year survival rates of those patients with their lesions less than 3cm in length,were 33.3% for medullary type patients and 5.0% for constrictive type patients(P<0.01).Conclusions:The prognosis of patients with less than 5cm in length esophageal carcinoma lesion,treated with radiotherapy,was closely related to their x-ray image changes(CR or PR) after the treatment.Patients with constrictive type esophageal carcinoma had the poor prognosis.
