EASL 2014:BCLC-B亚分类或对HCC患者预后有一定价值

2014-04-14 佚名 dxy

2012年最新公布的巴塞罗纳临床肝癌分期系统(BarcelonaClinic Liver Cancer Classification,BCLC)-B亚分类标准,将存在中间阶段异质性的肝细胞癌(HCC)人群,按Child-Pugh评分、肿瘤负荷(最大到七个标准)、ECOG –PS和门静脉血栓形成,进一步划分为4个亚组。然而,该分类法尚未得到外部广泛地验证。 奥地利维也纳医科大学消化内科Hucke等对

2012年最新公布的巴塞罗纳临床肝癌分期系统(BarcelonaClinic Liver Cancer Classification,BCLC)-B亚分类标准,将存在中间阶段异质性的肝细胞癌(HCC)人群,按Child-Pugh评分、肿瘤负荷(最大到七个标准)、ECOG –PS和门静脉血栓形成,进一步划分为4个亚组。然而,该分类法尚未得到外部广泛地验证。

奥地利维也纳医科大学消化内科Hucke等对此进行了一项HCC队列研究,旨在验证BCLC-B亚分类在接受TACE治疗的HCC患者中的临床价值。

研究收集1999年1月至2011年12月间就诊于维也纳医科大学的HCC患者信息,研究对象是确诊为BCLC-B期且接受TACE治疗的HCC患者。单因素分析变量为年龄、性别、病因、肿瘤大小、肿瘤数目、Child-Pugh分期以及BCLC-B亚分类。对于P< 0.05的变量纳入多元Cox回归模型。

研究共纳入202例HCC患者,男女比例为87%和13%,平均年龄67岁,主要病因为酒精性肝病(46%)。Child-Pugh分级A/B各占63%和37%。单因素分析显示,年龄、Child-Pugh分级、肿瘤大小和BCLC-B亚分类与整体生存期(OS)呈显著相关。

进而将这些因素纳入多元分析,结果显示,只有BCLC-B亚分类是独立的预后因素。BCLC-B1/B2/B3/B4分期的中位OS分别为28/14/11/9个月(P < 0.0001);然而,BCLC-B2-4亚分类间没有观察到显著的预后差异。

总体而言,BCLC-亚分类的预后价值在接受TACE治疗的HCC患者队列研究中得到一定地验证。但是,对于BCLC-B2-B4亚分类均普遍与不良预后相关,因而没有显示出与预后信息评估有关的临床价值,说明对于这部分人群还需要其他的评估工具进一步分层患者以评估预后。
