Objective: To evaluate the survival and prognostic factors of radiotherapy in patient with Ⅳ stage esophageal squamous carcinoma treated with radiation or chemoradiation. Methods: The medical records of 608 patients with stage Ⅳ esophageal squamous cell carcinoma who met the inclusion criteria in 10 medical centers in China from 2002 to 2016 were retrospectively analyzed. The overall survival and prognostic factors of all patients at 1, 3 and 5 years were analyzed. Results: The 1-, 3-, 5- year overall survival (OS) rates was 66.7%, 29.5% and 24.3% in stage ⅣA patients, and 58.8%, 29.0% and 23.5% in stage ⅣB patients. There was no statistical difference between the two groups (P=0.255). Univariate analysis demonstrated that the length of lesion, treatment plan, planned tumor target volume (PGTV) dose, subsequent chemotherapy, and degrees of anemia, radiation esophagitis, radiation pneumonia were related to the prognoses of patients with Ⅳ stage esophageal carcinomas after radiotherapy and chemotherapy (P<0.05). Multivariate analysis demonstrated that PGTV dose (OR=0.693, P=0.004), radiation esophagitis (OR=0.867, P=0.038), and radiation pneumonia (OR=1.181, P=0.004) were independent prognostic factors for OS. Conclusions: For patients with stage Ⅳ esophageal squamous cell carcinoma, chemoradiotherapy followed by sequential chemotherapy is recommended, which can extend the total survival and improve the prognosis of the patients. PGTV dose more than 60 Gy has better efficacy.
目的： 探讨晚期食管鳞癌患者放化疗的疗效，分析其预后影响因素。 方法： 收集2002—2016年10所医疗中心608例Ⅳ期食管鳞癌患者的病历资料和随访资料，分析患者预后的影响因素。 结果： ⅣA期食管鳞癌患者的1、3、5年生存率分别为66.7%、29.5%和24.3%，ⅣB期患者分别为58.8%、29.0%和23.5%，两组之间差异无统计学意义(P＝0.255)。单因素分析结果显示，病变长度、治疗方案、计划肿瘤体积(PGTV)剂量、是否序贯化疗、贫血程度、放射性食管炎程度、放射性肺炎程度与Ⅳ期食管鳞癌放化疗患者的预后有关(均P<0.05)。多因素分析显示，PGTV剂量(OR＝0.693, P＝0.004)、放射性食管炎程度(OR＝0.867，P＝0.038)、放射性肺炎程度(OR＝1.181，P＝0.004)是Ⅳ期食管鳞癌患者放化疗预后的独立影响因素。 结论： 对Ⅳ期食管鳞癌推荐放化疗后序贯化疗的综合治疗方案，能够延长患者的总生存时间，改善患者的预后。PGTV剂量≥60 Gy疗效较好。.
