BMC Cancer:他汀类药物治疗可能可增加NSCLC使用免疫治疗的疗效

2022-05-23 yd2015 网络

研究表明,他汀类药物治疗可能可增加NSCLC使用免疫治疗的疗效。但需要更大样本量的前瞻性研究进一步验证。

最近许多研究报道了药物与接受肿瘤免疫治疗的非小细胞肺癌(NSCLC)患者的反应和生存之间的关系。然而,他汀类药物治疗对NSCLC患者接受肿瘤免疫治疗的临床影响尚不清楚。近期,有相关结果发表在BMC Cancer杂志上,评估他汀类药物治疗对晚期NSCLC患者接受PD-1抑制剂单药免疫治疗的临床影响。

研究纳入2016年1月至2019年12月在日本3医疗中心的390例晚期或复发NSCLC患者,其接受PD-1抑制剂单药免疫治疗。评估他汀类药物对其生存的影响,使用倾向性匹配评分来减少混杂因素的影响。

390例患者中,中位年龄为67岁(范围31-88岁),其中309例(79.2%)为男性。390例患者中,53例(13.6%)接受了他汀类药物治疗,包括阿托伐他汀12例,匹伐他汀10例,普伐他汀9例,瑞舒伐他汀19例,辛伐他汀3例。326例患者有EGFR或ALK状态的数据(83.6%),261例患者有PD-L1数据(66.9%)。

Kaplan-Meier曲线显示,接受和未接受他汀治疗的患者的PFS或OS无显著差异(P=0.4777, P=0.5264);多因素分析显示ECOG PS (PS 1-3 vs PS 0: HR=1.36, P=0.0084)、吸烟史(从不吸烟vs.吸烟者:HR=1.37, P=0.0298)和PD-L1表达状态(其他人vs. TPS≥50%:HR=1.64, P<0.0001)是PFS的独立预后因素,而ECOG PS (PS 1-3 vs PS 0: HR=1.66, P=0.0001)和PD-L1表达状态(其他vs TPS ≥50%: HR=1.52, P=0.0026)是OS的独立预后因素。

使用倾向性匹配评分后,两组各有45例患者。Kaplan-Meier曲线表明,相比较于未接受他汀类药物治疗患者,接受他汀类药物治疗的患者有较长的OS (P = 0.0433),但PFS (P = 0.2251)没有差异。

倾向评分匹配队列的Cox回归分析显示,使用他汀类药物治疗不是独立的有利预后因素,尽管它倾向于与有利预后相关(使用vs.不使用:HR=0.61, P=0.0585)。

综上,研究表明,他汀类药物治疗可能可增加NSCLC使用免疫治疗的疗效。但需要更大样本量的前瞻性研究进一步验证。
