Liver Cancer:机体组成是索拉非尼治疗肝细胞癌患者预后的独立预测因子

2019-08-04 不详 MedSci原创

以前的研究表明,机体组成是晚期肝细胞癌(HCC)患者使用索拉非尼后毒性反应和预后的预测因子。本项研究的主要目的是验证机体组成在索拉非尼治疗的HCC患者中的预后价值。

背景:
以前的研究表明,机体组成是晚期肝细胞癌(HCC)患者使用索拉非尼后毒性反应和预后的预测因子。本项研究的主要目的是验证机体组成在索拉非尼治疗的HCC患者中的预后价值。

方法:
研究人员从2007年至2016年间在两个三级转诊中心回顾分析了接受索拉非尼治疗的一组HCC患者。通过计算机断层扫描(CT)在基线测量机体成分(脂肪和骨骼肌组织)。使用公布的截止值定义低骨骼肌质量(SMM)和密度。然后分析机体组成参数与总生存期(OS),进展时间,药物反应率和毒性相关。

结果:
本项研究共纳入278例患者,其中大多数为Child-Pugh A级(85%)和巴塞罗那临床肝癌(BCLC)C期(73%),中位OS为9.5个月。低SMM和低总脂肪组织指数(TATI)的患者(n= 68,25%)与其他患者(11.7,95%CI 9.4-14.0)相比,中位OS较差(5.8,95%CI 4.8-6.8)。在调整已知的预后因素后,低SMM和低TATI仍然是索拉非尼治疗肝细胞癌患者预后OS的独立预测因子(HR 1.56,95%CI 1.15-2.11,p = 0.004)。身体成分与索拉非尼毒性无关。

结论:
本项研究表明低SMM和低TATI与HCC患者存活受损相关,机体组成可以提供额外的预后信息。
