93例食管癌根治术后局部复发预后因素分析

Prognosis analysis of esophageal carcinoma patients with tumor Ioco-regional recurrence after curative surgery

目的 探讨食管癌根治术后局部复发患者的放射治疗疗效和预后影响因素.方法 回顾性分析食管癌根治术后局部区域复发行放射治疗93例患者的临床特点,结合随访资料进行预后因素分析,用Kaplan-Meier法和Logrank法分析比较生存率,用Cox模型进行多因素回归分析.结果 全组患者中位生存时间11.0个月（95%CI 9.4～12.6个月）,1、2、3年累积生存率分别为40.9%、10.1%和6.7%.单因素分析显示：患者年龄、PS评分、是否放化疗联合治疗、放射治疗剂量与预后相关;原发灶部位、术后复发间隔时间、以及转移灶数目均不影响预后.Cox模型多因素回归分析显示仅是否放化疗联合治疗、放射治疗剂量为独立预后因素.结论 食管癌根治术后复发放射治疗可以使部分患者生存时间延长,积极放化疗联合治疗、放射治疗剂量≥60 Gy者预后好.

Objective To evaluate the outcome of radiotherapy for recurrent esophageal cancer after surgery and to determine the prognostic factors. Methods From Jan 2004 to Dec 2009, 93 patients of esophageal carcinoma with loco-regional recurrence as the first site of failure after surgery were retrospectively reviewed. Kaplan-Meier method was used to analyze the survival. Logrank test was used to evaluate the difference between the groups. Multivariate survival analysis was conducted using a Cox proportional hazard regression model with a backward stepwise procedure. Results The overall survival rates at 1, 2 and 3 years were 40. 9% , 10. 1% and 6. 7% ,respectively,but with a median survival time of 11.0 months（95% CI 9. 4-12. 6） . In univariate analysis, age,PS, radiation dose and retreatment methods were independent prognostic factors. In multivariate analysis, only radiation dose and retreatment methods were independent prognostic factors for overall survival. Conclusions The prognosis of patients with postoperative loco-regional recurrence of esophageal cancer is poor. However, a long-term survival maybe expected by definitive chemoradiotherapy.
