Brit J Cancer:年龄对索拉非尼治疗肝细胞癌患者结局的影响

2020-10-21 MedSci原创 MedSci原创

老年人临床结局与<75岁的患者相似,且与索拉非尼剂量无关。

索拉非尼给药对老年肝细胞癌(HCC)患者疗效和毒性的影响尚无共识。老年患者通常从经验上开始采用低剂量治疗,其目的是避免毒性,同时最大程度地提高临床疗效。近日,肿瘤领域权威杂志British Journal of Cancer上发表了一篇研究文章,该研究旨在评估年​龄是否会影响总生存(OS),以及降低起始剂量是否会影响老年人OS或毒性。

在这项国际多中心队列研究中,研究人员确定了<75岁或≥75岁年龄组患者的结局,同时考虑了单变量和多变量模型中的常见预后因素和人口统计学特征。

该研究共招募了598名患者,≥75岁的受试者有792人(14.1%)。老年人更有可能发生较大的肿瘤(>7 cm)(39% vs. 33%,p<0.01),并保留了肝功能(67% vs. 57.7%)(p<0.01)。年龄≥75岁和<75岁的患者中位OS无差异(7.3个月 vs. 7.2个月;HR为1.00(95%CI为0.93–1.08),p=0.97)。<75岁和≥75岁的患者间,索拉非尼的起始剂量800mg vs. 400mg/200mg与OS之间没有关系。与<75岁的老年人相比,老年人发生2-4级索拉非尼相关毒性事件的总发生率相似(63.5 vs. 56.7%,p=0.11)。然而,老年人由于毒性而更可能停用索拉非尼(27.0 vs. 21.6%,p<0.01)。

由此可见,老年人临床结局与<75岁的患者相似,且与索拉非尼剂量无关。
