Relationship between preoperative FIB-4 and hepatocellular carcinoma prognosis after curative resection

摘要:
目的 探讨FIB(Fibrosis)-4评分系统与肝细胞癌(HCC)患者临床病理特征及预后的关系。 方法 收集2009年1月至2012年12月间245例接受根治性肝切除手术的HCC患者的临床及随访资料进行分析,利用Kaplan-Meier进行单因素生存分析,Cox比例风险回归模型进行多因素生存分析。 结果 根据患者术前FIB-4评分,将患者分为FIB-4Ⅰ(≤3.25)和FIB-4Ⅱ( > 3.25)。FIB-4能够预测肝硬化程度(Ishak分级:1~5级 vs. 6级,r=0.681,P < 0.001),其主要与患者的肝功能指标如谷草转氨酶(P < 0.001)、胆红素(P=0.009)、白蛋白(P=0.001)及血小板计数(P < 0.001)相关,与其他病理特征无关。单因素及多因素分析均表明FIB-4能够预测HCC患者的预后(总生存时间:P=0.037,0.011;无瘤生存时间:P=0.027,0.043)。 结论 FIB-4有可能作为HCC根治性切除术后的预后参考指标之一。 Abstract:Objective To investigate the correlation between FIB-4 and the clinicopathological characteristics and prognosis of patients with hepatocellular carcinoma (HCC) after curative resection. Methods From January 2009 to December 2012, the clinicopathological and follow-up data of 245 patients with HCC after curative resection were retrospectively studied. Their survival was calculated using the Kaplan-Meier method. The Cox proportional hazard regression model was used for the multivariate analysis. Results According to FIB-4 index, patients were divided into two subgroups: FIB-4Ⅰ(≤3.25) and FIB-4Ⅱ( > 3.25). FIB-4 could predict liver cirrhosis severity (Ishak grade, Grade 1-5 vs. Grad 6, r=0.681, P < 0.001). It was associated with liver function such as:aspartate transaminase (P < 0.001)、total bilirubin (P=0.009)、albumin (P=0.001) and platelet count (P < 0.001) other than tumor clinicopathologic features. Both univariate and multivariate analysis showed FIB-4 could predict the prognosis of HCC patients (Overall survival: P=0.037 and 0.011; Recurrencefree survival: P=0.027 and P=0.043, respectively). Conclusion The preoperative FIB-4 index could be used as a prognostic marker for the prognosis of HCC after curative hepatectomy. -
