目的评价Ⅰ～Ⅱ期食管癌根治术后放射治疗的价值。材料与方法１９８７年１月至１９９１年６月共收治１０３例术后病理为Ⅰ～Ⅱ期的食管癌。病人单纯手术７２例，术后放疗３１例，放疗剂量５０～６０Ｇｙ。结果术后随访≥５年，４７例复发，复发与ＴＮＭ分期有关，区域淋巴结和食管瘤床失败与食管原发部位有显著关系。单纯手术组，１，３，５年生存率为８７．５％、６９．４％、４１．７％；术后放疗组１，３，５年生存率为９０．３％、８３．９％、７４．２％，两组差异有显著性意义（Ｐ＜０．０１）。结论术后放疗复发率低，术后放疗组５年生存率高于单纯手术组。
Objective To evaluate the value of postoperative radiotherapy in patients with stage I to stage II esophageal cancer. Materials and Methods From January 1987 to June 1991, 103 cases of esophageal cancer with postoperative pathological stage I-II were treated. There were 72 patients undergoing simple surgery, 31 patients undergoing postoperative radiotherapy, and radiation doses of 50 to 60 Gy. Results Postoperative follow-up ≥ 5 years, 47 cases of recurrence, recurrence and TNM staging, regional lymph node and esophageal tumor bed failure and a significant relationship between the primary site of the esophagus. In the simple surgery group, the 1-, 3-, and 5-year survival rates were 87.5%, 69.4%, and 41.7%; the 1, 3, and 5-year survival rates of the postoperative radiotherapy group were 90.3%, 83.9%. 74.2%, the difference between the two groups was significant (P <0.01). Conclusions The postoperative radiotherapy has a low recurrence rate. The postoperative radiotherapy group has a higher 5-year survival rate than the surgery alone group.
