Clin Cancer Res:早期激素受体阳性乳腺癌患者的BRCAness和肿瘤炎症基因表达特征

2020-10-04 星云 MedSci原创

雌激素和(或)孕酮受体阳性的早期乳腺癌患者可受益于激素治疗,然而,由于高流行率和长期复发风险造成的全球高死亡负担需要生物标志物来指导其他治疗方法。

雌激素和(或)孕酮受体阳性的早期乳腺癌患者可受益于激素治疗,然而,由于高流行率和长期复发风险造成的全球高死亡负担需要生物标志物来指导其他治疗方法。

在一项前瞻性、观察性研究中,使用乳腺癌360个基因的panel对接受他莫西芬或芳香化酶抑制剂治疗的绝经后早期乳腺癌患者的612个肿瘤基因的表达进行了检测,以分析23条乳腺癌通路。通过聚类分析、Cox模型和条件推断树获得了与疾病亚型和无事件生存(EFS)相关的候选标记,并对613例乳腺标记患者进行了独立检测。在组织切片上评估肿瘤浸润淋巴细胞(TIL),通过全外显子组测序评估36种肿瘤的突变负担。

PAM50衍生的分类方法可将低风险(Luminal A)与高风险亚型(Luminal B)区分开来。在高风险患者中,较短的EFS与低雄激素受体(HR 3.61)或高BRCAness特征表达(HR 3.58)相关。BRCAness被独立地证实为EFS缩短的预测因子(HR 2.64)。约13-15%的患者,富集在高级别、高风险亚型,有肿瘤炎症特征(TIS)的高表达,提示抗肿瘤免疫应答受到抑制。TIS评分与TIL数量强相关,但与肿瘤突变状态无关。

总之,BRCA相关的DNA修复缺陷和肿瘤免疫反应抑制可能是内分泌治疗的临床相关预测因子,可补充激素敏感的早期乳腺癌亚群的治疗选择。
