将同一时期施行大肠癌根治术后存活１５年以上的３３例与存活１５年以下的６０例作对比分析。结果发现，大肠癌病人长期存活与性别、年龄、术式无关；长期生存主要取决于病期、组织学类型、大体类型、肿瘤原发部位、癌周免疫淋巴细胞反应、根治术加化疗等因素。 In the same period, 33 patients who survived after radical resection of colorectal cancer over a period of 15 years were compared with 60 patients who survived for 15 years or less. The results showed that the long-term survival of patients with colorectal cancer has nothing to do with gender, age, surgical methods; long-term survival depends on the stage of disease, histological type, general type, primary tumor site, cancer lymphocyte reaction, radical surgery plus chemotherapy and other factors .
