该大型研究表明肺腺癌患者中伴有KRAS G12C突变时预后较差。

驱动基因的突变在非小细胞肺癌(NSCLC)中起到重要的作用。KRAS突变也是NSCLC中常见的驱动基因突变之一,最高可占所有驱动基因的25%。但是一直以来,KRAS突变被认为是不可治疗的突变靶点。KRAS突变在NSCLC中的预后价值等还不是很明确。直到近期,针对KRAS-G12C (Kr_G12C)突变的两个抑制剂(AMG-510和 MRTX849)临床前试验证明有效,目前也处于临床试验中。近期,来自国外的研究团队利用欧洲胸部恶性肿瘤组(ETOP)Lungscape 数据库(iBiobank)开展了一项评估KRAS G12C突变在非小细胞肺癌(NSCLC)的预后作用的研究,相关结果发表在了Journal of Thoracic Oncology杂志上。

研究数据表明,2055例患者进行KRAS基因检测,其中1014例为腺癌(49%)。腺癌中有54%为男性, 中位年龄为66岁, 81%有吸烟史, 57%患者ECOG评分为0或1分。腺癌患者中I、II、III期分别占53%、24%和22%。

2055例患者中,有473例患者发现KRAS突变(23.0%, 95% CI: 21.2%–24.9%),有216例患者发现Kr_G12C (10.5%, 95% CI:9.2%–11.9%)。1014例腺癌患者中,有385例患者发现KRAS突变(38.0%, 95% CI: 35.0%–41.0%), 有172例患者发现Kr_G12C突变(17.0%, 95% CI: 14.7%–19.4%)。

中位随访时间为57.1个月。腺癌患者中,Kr_G12C突变患者中位OS为59.4个月, KRAS其他突变患者中位OS为81.7个月,无突变患者的中位OS为72.0个月。Kr_G12C突变对比KRAS其他突变患者的HR=1.39 (95% CI: 1.03 to1.89, p = 0.031),而对比无KRAS突变患者的HR=1.32(95% CI: 1.03 to 1.69, p =0.028)。

                        各组os对比

腺癌患者中,Kr_G12C突变患者中位RFS为46.7个月, KRAS其他突变患者中位RFS为55.3个月,无突变患者的中位RFS为50.3个月。Kr_G12C突变对比KRAS其他突变患者的HR=1.30, (95% CI: 0.98–1.72, p= 0.070),而对比无KRAS突变患者的HR=1.23(95% CI: 0.98–1.56,p= 0.066)。

                  各组RFS对比

腺癌患者中,Kr_G12C突变患者中位疾病复发时间(TTR)为66.6个月, KRAS其他突变患者中位TTR为85.8个月,无突变患者的中位TTR为84.6个月。Kr_G12C突变对比KRAS其他突变患者的HR=1.41, (95% CI: 1.03–1.92, p= 0.030),而对比无KRAS突变患者的HR=1.27(95% CI:0.99 to 1.64, p=0.063)。

               各组TTR对比

综上,该大型研究表明肺腺癌患者中伴有KRAS G12C突变时预后较差。
