Trastuzumab可以改善HER2阳性乳腺癌患者的预后。ANN ONCOL近期发表了一篇文章,研究Trastuzumab是否可以降低高风险,HER2未扩增早期乳腺癌患者的循环肿瘤细胞检测率。

研究纳入确诊为HER2未扩增且每15ml血循环肿瘤细胞≥1个的乳腺癌患者,患者接受手术及辅助化疗后随机1:1分为Trastuzumab治疗6个周期组或18周观察组。主要的研究终点为第18周每15ml血循环肿瘤细胞≥1个的检测率。次要的研究终点为侵袭性无病生存(iDFS)和心脏安全性。在2013年4月至2016年10月间,共监测了1317例患者。95例患者可以检测到循环肿瘤细胞,63例进行了随机分组。58例患者进行了主要研究终点分析,每组29例。58例患者中有9例在18周仍可检测到循环肿瘤细胞,其中Trastuzumab组5例,观察组4例。中位随访时间为13个月,观察组1年iDFS为93.8%,Trastuzumab组为84.4%。在Trastuzumab组未观察到2-4级心脏事件。

文章最后认为,Trastuzumab不能降低HER2未扩增,非转移性乳腺癌的循环肿瘤细胞检测率。
