JAMA:非小细胞肺癌患者肿瘤突变特征与预后

2019-04-10 MedSci MedSci原创

研究认为,非小细胞肺癌患者临床治疗效果与基因组图谱存在显著相关性,这一发现证明了从常规临床经验中建立临床基因组数据库的可行性,并为靶向肿瘤治疗学方法的进一步研究和发现提供了支持

将全面基因组图谱(CGP)与临床结果相关联可加速精确医学的发展,近日研究人员就非小细胞肺癌患者基因特征与预后的相关性进行了考察。

研究提取了4064名非小细胞肺癌患者基因信息,包括驱动基因、肿瘤突变负担(TMB,定义为每兆位突变的数目)以及其他临床特征。研究的主要终点为总生存期、最大治疗响应以及临床治疗收益。

患者平均年龄66.0岁,女性占51.9%,78.3%具有吸烟史,非鳞状细胞癌占77.6%, EGFR,ALK或 ROS1突变占21.4%(其中EGFR突变占17.2%, ALK突变占3.1%、 ROS1移位突变占1.0%),7年内1946人死亡。对于存在突变的患者,接受靶向治疗(n=575)相比于未接受靶向治疗(n=560)人群的总生存期显著延长(18.6 vs 11.4个月)。吸烟人群TMB显著高于非吸烟人群(8.7 vs 2.6)。存在EGFR(3.5 vs 7.8), ALK(2.1 vs7.0)、RET (4.6  vs 7.0)或 ROS1(4.0 vs 7.0)突变患者的TMB负担显著低于未突变人群。对于接受PD1/PD-L1治疗的患者(n=1290, 31.7%),TMB 20 以上人群相比于20以下人群,在生存期改善(16.8 vs 8.5个月)、治疗时间(7.8 vs 3.3个月)以及临床收益方面(80.7% vs 56.7%)更具优势。

研究认为,非小细胞肺癌患者临床治疗效果与基因组图谱存在显著相关性,这一发现证明了从常规临床经验中建立临床基因组数据库的可行性,并为靶向肿瘤治疗学方法的进一步研究和发现提供了支持。
