老年人肝细胞癌切除术后预后因素分析

目的 探讨老年肝细胞癌患者手术切除术后影响生存的因素.方法回顾性分析1995年1月至2002年12月连续手术切除的老年肝细胞癌患者54例,Kaplan Meier法统计术后生存期并进行单因素分析,Cox回归法进行多因素分析.结果Child-Pugh分级、脉管侵犯、卫星灶形成、病理学Edmondson-Steiner分级、肝内复发和远处转移影响老年肝细胞癌患者术后总体或无瘤生存（P＜0.05）.其中,Child-Pugh分级和脉管侵犯为术后总体生存的独立影响因素（相对危险度分别为3.37和2.73,P＜0.05）,而脉管侵犯独立影响无瘤生存（相对危险度为3.19,P＜0.05）.结论生物学行为和肝功能状况是影响老年人肝细胞癌预后的主要因素.

Factors affecting postoperative prognosis of elderly patients with hepatocellular carcinoma

Objective To determine factors affecting postoperative survival of elderly patients with hepatocellular carcinoma (HCC). Methods A retrospective analysis of consecutive 54 elderly patients undergoing hepatectomy for hepatocellular carcinoma from Jan 1995 to Dec 2002 was performed. The data were analyzed by Kaplan-Meier method and Cox regression. Results Univariate analysis and Cox regression showed Child Pugh grading, vessel invasion, satellite nodule formation, Edmondson Steiner grading, intrahepatic recurrence and distant metastasis all related to postoperative overall survival or disease-free survival of the elderly with hepatocellular carcinoma (all P<0.05). Of them, Child-Pugh grading and vessel invasion were independent risk factors for overall survival (Relative risks were 3.37 and 2.73, respectively, all P<0. 05), and vessel invasion independently influenced disease-free survival (Relative risk was 3.19, P<0.05). Conclusions Biological behaviors of the tumor and liver function status are major factors influencing the prognosis of hepatocellular carcinoma in the elderly.
