JAMA Oncol:对于激素受体阳性乳腺癌,帕博西尼 ➕来曲唑 优于帕博西尼 ➕氟维司群

2021-10-19 MedSci原创 MedSci原创

在内分泌敏感、激素受体阳性、ERBB2阴性晚期乳腺癌患者中,来曲唑是帕博西尼的首选合作伙伴。

乳腺癌是女性的头号杀手。在2020年,全球新增 226 万 万乳腺癌症患者乳腺癌的新增人数已经超过了肺癌,成为全球第一大癌症。

2020年癌症新发病例数前十的癌症类型

随着医学的进步激素受体阳性乳腺癌的药物也越来越多比如Palbociclib(帕博西尼)、来曲唑和氟维司群

Palbociclib(帕博西尼)是全球首个批准上市的CDK4/6激酶抑制剂,是一种实验性、口服、靶向性CDK4/6抑制剂,可阻断肿瘤细胞的增殖,是治疗晚期乳腺癌的一种药物。作为口服治疗药物,医学界认为CD4/6靶点药物帕博西尼和HER2靶点药物曲妥珠单抗(赫赛汀)是如今针对性治疗乳腺癌比较好的靶向药物。

帕博西尼在国内上市后,改成爱博新。

在临床中,帕博西尼和来曲唑、氟维司群的联合治疗都优于来曲唑或氟维司群的单独治疗效果但是对于先前未经治疗的内分泌敏感、激素受体阳性、ERBB2阴性晚期乳腺癌中,帕博西尼的最佳内分泌搭档是氟维司群还是来曲唑呢?

近期一项发表在JAMA oncology 上的一项研究表明,氟维司群- 帕博西尼与来曲唑- 帕博西尼 相比在无进展生存期方面没有改善,证实来曲唑是该患者群体中首选的帕博西尼合作伙伴。

在这项于2015年7月30日-2018年1月8日期间进行的国际、随机、开放标签、2 期临床研究中,受试者为激素受体阳性、ERBB2阴性、既往未接受过治疗的晚期乳腺癌患者

患者被随机分配(1:1 比例)接受 帕博西尼 和氟维司群或来曲唑。分层因素是疾病表现的类型(新发与复发)和内脏受累的存在(是与否)。主要终点是研究者评估的无进展生存期,该无进展生存期由实体瘤反应评估标准 1.1 版确定。

研究结果发现氟维司群-帕博西尼组的中位研究者评估无进展生存期为 27.9 个月(95% CI,24.2-33.1 个月),而来曲唑-帕博西尼组为 32.8 个月(95% CI,25.8-35.9 个月)(风险比, 1.13;95% CI,0.89-1.45;P = .32)。差异无统计学意义。这一结果在所有分层因素中都是一致的。

此外氟维司群-帕博西尼和来曲唑帕博西尼的客观缓解率(46.5% 对 50.2%)和3年总生存率(79.4% 对 77.1%)未观察到显着差异。3-4 级不良事件在治疗组之间具有可比性,并且没有发现新的安全性信号。没有报告与治疗相关的死亡。

尽管氟维司群-palbociclib 显示出显著的抗肿瘤活性,但这项随机临床试验未能确定在内分泌敏感、激素受体阳性、ERBB2阴性晚期乳腺癌患者中,该方案与来曲唑-palbociclib 相比可改善无进展生存期癌症因此,来曲唑是该患者群体中首选的帕博西尼合作伙伴。
