铂类和PARP抑制剂可为双位基因状态的胰腺癌提供长久获益

2021-08-06肿瘤情报组原创:医学界肿瘤频道

携带生殖系/体细胞BRCA1/BRCA2突变(g/sBRCA1/2)是胰腺导管腺癌(PDAC)的独特生物学亚组。近日有研究发现:在具有双等位基因状态的g/sBRCA1/2突变的患者中,铂类和PARP抑制剂提供了可观且持久的获益。

在2011年1月至2020年6月期间,共确定了136例g/sBRCA1/2患者。对于接受一线铂类药物治疗的IV期疾病患者,双等位基因患者(n=39)的中位OS为26个月(95%CI,20-52个月),杂合子患者(n=4)为8.66个月(95%CI,6.2个月至未达到)。对于接受PARP抑制剂治疗的患者,双等位基因患者(n=25)的中位OS为26.5个月(95%CI,24-53个月),杂合子患者(n=2)的中位OS为8.66个月(95%CI,7.23个月至未达到)。
