Br J Cancer:RAS突变对于早发性和晚发性结直肠癌肝转移切除患者总体生存期的影响

在美国,结直肠癌(CRC)是癌症相关死亡的第三大主要原因。近年来,由于筛查方法的改进和治疗选择的增加,CRC的发生率和死亡率显著下降。然而,尽管总体CRC发病率有所下降,但55岁以下人群的CRC发病率

在美国,结直肠癌(CRC)是癌症相关死亡的第三大主要原因。近年来,由于筛查方法的改进和治疗选择的增加,CRC的发生率和死亡率显著下降。然而,尽管总体CRC发病率有所下降,但55岁以下人群的CRC发病率每年增加约2%,其原因目前尚不清楚。

生活方式和环境因素可能是早发性结直肠癌(EOCRC)发病率增加的原因,肥胖目前已被认为主要的发病因素。EOCRC具有明显的分子遗传异质性。既往研究分析了EOCRC和晚发性CRC(LOCRC)的基因组特征,虽然总体上具有许多相似之处,但研究人员发现特定突变的发生率存在明显差异。EOCRC与LOCRC患者预后比较的相关研究也显示出矛盾的结果


因此,根据CRC发病年龄了解常见突变的临床相关性可能有助于开发独特的治疗策略,并预测个性化疗法对于EOCRC患者的潜在影响。而目前特定的基因突变对于结直肠癌肝转移(CLM)切除后的EOCRC与LOCRC患者的影响尚不明确。

RAS突变状态的患者总生存率

该研究旨在探究RAS突变对于接受结直肠癌肝转移(CLM)根治性切除术的EOCRC和LOCRC患者总体生存期(OS)的影响。研究人员通过分析CLM肝切除术患者的RAS、BRAF和MSI状态,以年龄作为分类变量和连续变量,分析按年龄划分的RAS突变对患者预后的影响。


该研究共包括573例患者,192例EOCRC和381例LOCRC。研究显示,CRC的发病年龄越年轻,对LOCRC、EOCRC和≤40岁的RAS突变总体生存的负面影响就越大(危险比(HR)分别为1.64、2.03和2.97)。特定年龄段的死亡风险和线性回归分析显示,RAS突变对于EOCRC患者生存的影响大于LOCRC。

按年龄分类的死亡风险

综上,该研究结果显示,在接受CLM切除的患者中,相比于LOCRC患者,RAS突变对于EOCRC患者的生存具有更大的负面影响,特别是对于40岁以下的患者,因此,应将其视为该疾病治疗策略中的一个重要的预后因素。
