这是一项前瞻性的Ⅲ期随机对照研究,探索曲妥珠单抗联合内分泌治疗在HR/HER2阳性晚期乳腺癌患者中的疗效。结果显示,曲妥珠单抗联合阿那曲唑较阿那曲唑单药治疗显著延长了患者的PFS,由于阿那曲唑组70%的患者进展后交叉至曲妥珠单抗治疗,因此两组OS没有差别。3~4级不良事件的发生率轻度增加。

在HR/HER2阳性晚期乳腺癌患者中,拉帕替尼联合来曲唑较安慰剂来曲唑显著提高PFS和临床获益率,总生存有延长的趋势。本研究结果提示拉帕替尼联合来曲唑可作为HR/HER2阳性晚期乳腺癌的治疗选择。

方案Ⅲ 曲妥珠单抗、帕妥珠单抗双靶联合AI治疗

点评
本研究入组了258例ER/PR和HER2阳性的晚期乳腺癌患者。结果显示,帕妥珠单抗、曲妥珠单抗双靶联合AI较曲妥珠单抗联合AI显著提高了PFS,双靶治疗组3级以上不良事件的发生率也较曲妥珠单抗联合AI组显著增加。由于本研究患者入组前约一半患者接受了紫杉醇的诱导化疗(18~24周),因此总体PFS时间较长。
