胃癌根治术后肝转移的预后分析

目的探讨影响胃癌根治术后肝转移患者预后的相关因素。方法总结我院1996年至2001年间收治的胃癌根治术后发生肝转移患者87例的临床病理资料，回顾分析影响所有胃癌根治术后肝转移患者预后的相关临床病理因素。结果胃癌根治术后肝转移患者1、3和5年生存率分别为28．8％、3．6％和0，平均生存时间为（11．3±1．1）个月。单因素分析显示：原发灶部位、原发灶大小、分化程度、浸润深度、Lauren分型、淋巴结转移、血管浸润、神经浸润、腹膜转移、转移灶数目、转移灶肝内分布类型及转移灶切除与胃癌根治术后肝转移的预后显著相关。而多因素分析显示：仅原发灶部位、Lauren分型、转移灶肝内分布类型和转移灶切除是影响胃癌根治术后肝转移预后的独立因素。结论原发灶部位、Lauren分型、转移灶肝内分布类型和转移灶切除与否是评价胃癌根治术后肝转移患者预后的重要参考因素。

Prognostic analysis of liver metastasis in gastric cancer patients with radical gastrectomy

OBJECTIVE: To elucidate the prognostic factors of liver metastasis in gastric cancer patients with radical gastrectomy. METHODS: Clinicopathological data of 87 liver metastasis patients, undergone radical gastrectomy for gastric cancer from 1996 to 2001, were retrospectively analyzed. RESULTS: Of these 87 patients, the 1-, 3- and 5-year survival rates were 28.8%, 3.6% and 0 respectively and the average survival time after gastrectomy was (11.3+/-1.1) months. By univariate analysis, tumor location, tumor size, histologic differentiation, invasive depth, Lauren classification, metastasis of lymph nodes from lymphadenectomy, vascular invasion, nervous invasion, peritoneal metastasis, number of liver metastasis, liver metastatic distribution and resection of liver metastasis were found to be significant factors associated with the prognosis of liver metastatic patients after radical gastrectomy. By multivariate analysis, location, the Lauren classification, liver metastatic distribution and resection of liver metastasis were found to be independent factors associated with hepatic metastasis after radical gastrectomy. CONCLUSION: Location of gastric cancer, Lauren classification, liver metastatic distribution and resection of liver metastasis are important factors to evaluate the prognosis of liver metastasis in gastric cancer patients with radical gastrectomy.
