背景:对于具有大量肝转移灶的结肠癌病人,手术切除可能是有效的治疗方法,但其确切的益处尚不清楚。方法从两个具有大样本容量的肝脏外科中心收集1998至2012年间施行手术切除的结肠癌肝转移的病人数据,并根据其转移灶的数量进行分组:组1(转移灶<8),组2(转移灶≥8)。比较两组的总体生存率及无复发生存率,并通过多因素分析确定其不良预后因素。结果共有849人纳入研究,其中组
Background: Surgical resection may be an effective treatment for colon cancer patients with a large number of liver metastases, but its exact benefits are not yet known. Methods Patients with resected liver metastases from colon from 1998 to 2012 were collected from two large liver volume surgical centers and grouped according to their number of metastases: group 1 (metastasis <8), group 2 (Metastasis ≥8). The overall survival rate and recurrence-free survival rate were compared between the two groups, and the adverse prognostic factors were determined by multivariate analysis. A total of 849 patients were included in the study, of which group
