曲妥珠单抗在乳腺癌中的临床成功告诉我们,为了正确识别有资格接受靶向治疗的患者,必须进行适当的肿瘤评估。虽然免疫组织化学(IHC)检测HER2蛋白表达和荧光原位杂交(FISH)检测基因扩增通常用于选择接受曲妥珠单抗治疗的患者,但这两种检测方法都只能部分预测药物的疗效。在表皮生长因子受体(EGFR)的情况下,无法证明该受体的存在或其扩增与抗EGFR治疗反应之间的联系。对HER3和HER4的了解更少,主要是因为缺乏可靠和有效的检测这些蛋白质的方法。越来越明显的是,除了FISH和IHC,我们还需要更好的检测方法来量化她的受体,并对患者进行个性化治疗。在这里,我们介绍了目前可用的方法来测量她的家族受体,并讨论了目标量化的临床意义。本文的在线版本(doi:10.1186/s13058-0150561-8)包含补充材料,可供授权用户使用。
The clinical success of trastuzumab in breast cancer taught us that appropriate tumor evaluation is mandatory for the correct identification of patients eligible for targeted therapies. Although HER2 protein expression by immunohistochemistry (IHC) and gene amplification by fluorescence in situ hybridization (FISH) assays are routinely used to select patients to receive trastuzumab, both assays only partially predict response to the drug. In the case of epidermal growth factor receptor (EGFR), the link between the presence of the receptor or its amplification and response to anti-EGFR therapies could not be demonstrated. Even less is known for HER3 and HER4, mainly due to lack of robust and validated assays detecting these proteins. It is becoming evident that, besides FISH and IHC, we need better assays to quantify HER receptors and categorize the patients for individualized treatments. Here, we present the current available methodologies to measure HER family receptors and discuss the clinical implications of target quantification.
