应用Log－rank检验及Cox模型，对174例行根治性手术的食管癌患者进行单因素和多因素预后分析，从8个预后因素中筛选出转移情况、组织分型、住院时间、出院治疗4个因素对食管癌预后有显著影响。转移情况是直接影响行根治性手术治疗食管癌预后的重要因素（P＜0．001），鳞癌患者较腺癌患者预后为好（P＜0．05），同时，住院时间、出院治疗与预后均存在显著性意义。提示根治性手术虽是治疗食管癌的首选治疗手段，但也应与其他治疗方法综合应用，这样才能有效抑制肿瘤的转移和（或）复发，使患者获得较长期的生存。
Log-rank test and Cox model were used to analyze the univariate and multivariate prognostic factors of 174 patients undergoing radical surgery for esophageal cancer. The metastatic status, histological type, length of stay, and discharge from hospital were selected from 8 prognostic factors. These factors have a significant impact on the prognosis of esophageal cancer. Metastasis was an important factor directly affecting the prognosis of radical surgery for esophageal cancer (P<0.001). The prognosis of squamous cell carcinoma patients was better than that of adenocarcinoma (P<0.05). Meanwhile, hospitalization time, discharge from hospital and The prognosis was significant. Although radical surgery is the first choice for the treatment of esophageal cancer, it should also be combined with other treatment methods to effectively inhibit tumor metastasis and (or) recurrence, so that patients can obtain a longer-term survival.
