摘要目的 分析食管癌根治术后复发挽救治疗的疗效,为综合治疗提供依据.方法 回顾分析2004-2014年间食管癌R0术后复发转移行挽救治疗的218患者资料.采用Kaplan-Meier法计算生存率并Logrank法检验和单因素预后分析,Cox模型多因素预后分析.结果 全组患者复发后中位随访时间53个月.复发后1、3年OS率分别为57.2%、24.4%.163例局部区域复发患者复发后放化疗(40例),单纯放疗(106例),支持治疗(13例)的1、3年OS率分别为70%、42%,55%、24%,23%、8%(放化疗比单纯放疗P=0.045,单纯放疗比支持治疗P=0.004,单纯化疗无1年生存).单因素分析显示术后病理N分期、TNM分期、复发后治疗方式影响预后(P均=0.001),多因素分析中只有复发后治疗方式是影响生存的独立预后因素(P=0.013).结论 食管癌根治术后复发转移后采用放化疗或放疗挽救治疗有明显生存获益,特别是局部区域复发患者.

abstractsObjective To evaluate the efficacy of rescue treatment for recurrent esophageal cancer after radical esophagectomy, and to provide insights into the development of comprehensive treatment for esophageal cancer.Methods The clinical data of 218 patients who were confirmed with recurrent metastatic esophageal cancer after R0 resection and received rescue treatment in our hospital from 2004 to 2014 were retrospectively reviewed.The survival rate was determined by the Kaplan-Meier method.Univariate and multivariate prognostic analyses were performed using the log-rank test and Cox proportional hazards model, respectively.Results The median post-recurrence follow-up time was 53 months.The 1-and 3-year overall survival (OS) rates after recurrence were 57.2% and 24.4%, respectively.Among the 163 patients with local recurrence, the 1-and 3-year OS rates were 70% and 42% for patients treated with chemoradiotherapy (n=40), 55% and 24% for those with radiotherapy alone (n=106), and 23% and 8% for those with supportive therapy (n=13)(chemoradiotherapy vs.radiotherapy alone P=0.045, radiotherapy alone vs.supportive therapy P=0.004;none of the patients who were treated with chemotherapy alone survived for one year or more).Univariate analysis showed that N staging, TNM staging, and post-recurrence rescue treatment regimen were independent prognostic factors for esophageal cancer (all P=0.001).On the other hand, multivariate analysis indicated that only rescue treatment regimen was the independent prognostic factor for esophageal cancer (P=0.013).Conclusions Rescue chemoradiotherapy or radiotherapy alone can bring significant survival benefits for patients with recurrent and metastatic, especially locally recurrent, esophageal cancer following radical esophagectomy.
