摘要

约40%的激素受体阳性(HR+)、HER2阴性(HER2-)乳腺癌存在PIK3CA(编码PI3Kα的催化亚基)激活突变;这些突变通常与预后不良有关,但也与对PI3K-AKT通路抑制剂的反应性有关。现在,Ⅲ期INAVO120试验的数据表明,在治疗晚期疾病的一线内分泌加CDK4/6抑制剂标准疗法中加入选择性PI3Kα抑制剂和降解剂inavolisib是可行的,而且能提高疗效。在INAVO120研究中,325名PIK3CA突变HR+、HER2-乳腺癌转移性复发患者在接受辅助内分泌治疗期间或完成治疗后12个月内被随机分配(1:1)接受palbociclib和氟维司群加inavolisib或安慰剂治疗。预后较差的患者需要接受早期疾病复发治疗:83%的患者接受过化疗,80%的患者有内脏转移,52%的患者有肝转移,51%的患者有≥3个转移灶。但值得注意的是,只有1%的患者在辅助治疗中使用过CDK4/6抑制剂。无进展生存期(PFS)是主要终点。
