目的分析三维适形放射治疗(3DCRT)中晚期食管癌的疗效。方法采用3DCRT放射治疗中晚期食管癌65例做回顾性分析,65例患者均为住院患者,均已病理证实。先常规放疗20Gy,2Gy/次,5次/周,然后改为3DCRT,2Gy/次,5次/周,总剂量60Gy~66Gy,7周内完成。评价依据为放疗结束时的临床症状及放疗结束后3个月的食管钡餐片、CT片。结果完全缓解(CR)27例,部分缓解(PR)38例,总有效率(PR+CR)为100%,近期疗效与靶区体积及病理类型有关,病灶体积越小效果越好。结论3DCRT对于中晚期食管癌具有显著的临床疗效,副作用轻微,是一种疗效可靠的治疗方法。
Objective To analyze the effect of three-dimensional conformal radiotherapy (3DCRT) on advanced esophageal cancer. Methods We retrospectively analyzed 65 cases of advanced esophageal carcinoma with 3DCRT radiotherapy. All of the 65 patients were hospitalized, which were confirmed by pathology. The first routine radiotherapy 20Gy, 2Gy / times, 5 times / week, and then changed to 3DCRT, 2Gy / times, 5 times / week, the total dose of 60Gy ~ 66Gy, completed within 7 weeks. Evaluation based on the clinical symptoms at the end of radiotherapy and esophageal barium meal, CT film 3 months after the end of radiotherapy. Results The complete remission (CR) in 27 cases, partial remission (PR) in 38 cases, the total effective rate (PR + CR) was 100%, the short term efficacy and target volume and pathological type, the smaller the lesion volume, the better. Conclusions 3DCRT has a significant clinical effect on advanced esophageal cancer with mild side effects and is a reliable and reliable treatment.
