The present invention relates to methods for estimation of efficacy of therapeutic treatment of cancer patients, in particular breast cancer patients. The estimation is based on determining of the status of aberration of the estrogen receptor alpha gene (ESR1) in situ, and, optionally, the status of aberration of a gene related to ESR1. In particular, the invention relates to determining the presence or absence and, if present, the type of aberration, e.g. amplification, duplication, polyploidization, deletion or translocation of the ESR1 gene in the tumor cells of the patient. The invention further relates to a kit-in-parts comprising probes for the determining the status of aberration of ESR1 and ESR1-related genes in situ.
本发明涉及一种用于估计治疗癌症患者(特别是乳腺癌患者)疗效的方法。该估计基于在原位确定
雌激素受体α
基因(ESR1)的异常状态,以及可选地,与ESR1相关的
基因的异常状态。特别地,本发明涉及确定患者肿瘤细胞中ESR1
基因的扩增、重复、多倍体化、缺失或易位等异常类型的存在或缺失。本发明还涉及一种包含探针的分部套件,用于在原位确定ESR1和ESR1相关
基因的异常状态。
