1992年1月至1993年5月，我科收治32例食管癌手术后病理证实食管残端癌残留和／或区域淋巴结癌转移的病员，采用术后放疗交替化疗方式治疗，其1、2、3年生存率分别为78.13％、56.25％和15．62％，与我科同期采用单纯术后放疗的食管疾病例作回顾性比较，1、2年生存率无差别，3年生存率低于术后单纯放疗组，进一步分析，发现生存率与病员的细胞免疫状态相关，过度的治疗，对病员的生存率的提高无益。
From January 1992 to May 1993, the Department of Pathology confirmed the pathological diagnosis of residual stump cancer and/or regional lymph node metastasis in 32 patients with esophageal cancer after operation. The patients were treated with alternating radiotherapy after radiotherapy. The three-year survival rates were 78.13%, 56.25%, and 15.62%, respectively. The retrospective comparison of esophageal diseases with postoperative radiotherapy at the same time in our department showed no difference in 1- and 2-year survival rates, and the 3-year survival rate was lower. After the radiotherapy alone group, further analysis revealed that the survival rate was related to the patient’s cellular immune status, and excessive treatment did not benefit the patient’s survival rate.
