047-RAS抑制剂在癌症治疗中的应用

12 Aug 2025

Description

RAS癌蛋白是癌症发生和进展的关键驱动因素,在近20%的癌症病例中存在激活突变,其中KRAS是最常见的。虽然KRAS抑制剂在非小细胞肺癌(NSCLC)、结直肠癌(CRC)和胰腺导管腺癌(PDAC)等多种癌症类型中显示出早期疗效,但单药治疗的临床效果因原发性和获得性耐药而受限。本简报详细审查了RAS抑制在癌症治疗中的临床前和临床数据,描述了多种遗传和非遗传耐药机制,并强调了未来通过合理组合疗法克服耐药和增强治疗效果的机会。References: Ebright R Y, Dilly J, Shaw A T, et al.
