胃癌肝转移的肝切除治疗及预后分析

目的 探讨胃癌肝转移肝切除治疗的疗效以及不同临床病理因素与预后的关系.方法 回顾性总结24例胃癌肝转移行肝转移灶手术切除患者的临床资料并对预后进行单因素和多因素分析.结果 全组病例均获得随访,胃癌肝转移外科治疗后1年生存率为67%,3年生存率为21%,5年生存率为13%.单因素分析显示淋巴结转移、脉管瘤栓、R0切除、转移灶大小为重要预后因素;多因素分析显示转移灶大小、脉管瘤栓为独立预后因素.结论 严格适应证的胃癌肝转移手术切除可以改善预后.综合治疗有望进一步提高疗效.

Hepatectomy for metastatic liver carcinoma in patients of gastric cancer

Objective To investigate the effectiveness of surgical resection for metastatic liver cancer in patients of gastric carcinoma, and evaluate the prognosis. Methods Clinical data of 24 gastric cancer cases undergoing hepatectomy for hepatic metastatic tumor were collected retrospectively. There were 18 cases of synchronous resection and 6 cases of heterochronous resection. The prognostic values of clinicopathological factors were assessed by univariate and multivariate analyses. Results Postoperatively all cases were followed up until the death of the patietns. Counting from the time of liver resection the 1-,3- and 5-year survival rate was 67%, 21% and 13% respectively. Univariate analysis showed lymph node involved, tumor size of hepatic metastases, vascular invasion and R0 margin as significant prognostic factors;Multivariate analysis indicated that tumor size of hepatic metastases and vascular invasion were independent prognostic factors influencing the survival. Conclusion These results suggest that for patients with liver metastasia from gastric cancer, better prognosis can be obtained by surgical treatment.
