EBCC 10:HER2+乳腺癌福音!术前短期治疗即可

2016-03-24 zhaoshuang译 MedSci原创

第十届欧洲乳腺癌大会(EBCC-10)称,HER2+乳腺癌在术前或化疗前使用妥珠单抗+拉帕替尼联合治疗11天后,近25%的患者其肿瘤组织明显缩小或消失。

第十届欧洲乳腺癌大会(EBCC-10)称,HER2+乳腺癌在术前或化疗前使用妥珠单抗+拉帕替尼联合治疗11天后,近25%的患者其肿瘤组织明显缩小或消失。


该研究纳入了257名HER2+乳腺癌患者,在术前分为接受曲妥珠单抗、拉帕替尼、曲妥珠单抗+拉帕替尼治疗和无治疗组。术后接受标本的治疗。使用确诊时和手术时获取的肿瘤标本,分析术前治疗对标本中Ki67 蛋白影响情况,或两次活检中细胞凋亡是否达到30%。根据病理缓解情况分为完全缓解(pCR,无活动性癌细胞)、极小残留(MRD,肿瘤小于5mm)和其它。

研究数据显示,曲妥珠单抗+拉帕替尼组患者肿瘤标本中Ki67下降,且有11%和17%的患者达到 pCR和MRD,需指出的是,病理缓解的患者中存在淋巴结受累的Ⅱ期乳腺癌患者。此外,曲妥珠单抗组达到pCR和MRD的患者只有0%和3%,而对照组没有患者达到pCR或MRD。

英国癌症研究院首席研究员 Judith Bliss 教授说:“当前的大多数乳腺癌研究的关注点在于治疗后几个月内的病理缓解,而这项研究的关注点却在术前,HER2+乳腺癌只需术前短期治疗,就可以根据病理缓解情况拟定下一步治疗,确定患者是否还需要化疗。不过未来还需要更多的研究,以验证该结果。”

里斯本 Champalimaud 临床中心乳腺科主任 Fatima Cardoso 教授说:“HER2+乳腺癌患者只需术前进行短期的曲妥珠单抗+拉帕替尼双靶向治疗就可以明确患者是否需要化疗,不过这种早期的病理缓解能否持续下去,改善患者的长期生存,仍是未知的,还需要更多的研究。”
