这项研究的结果在2016年胃肠道癌症研讨会上宣讲的。科罗拉多大学医学院Christopher Lieu指出,青年和老年结直肠癌患者肿瘤样本有明显的遗传差异。 

虽然美国整体结直肠癌发生率降低,但是50岁以上的成年人患结直肠癌的发病率上升10%左右。

Lieu教授和同事们通过对近期的数据分析后也发现,年轻的肿瘤患者病情恶化更快,死亡的风险更高。 

这项研究的目的是密切地观察任何可能解释青年及中老年人结直肠癌的遗传原因差异及为何年轻人肿瘤死亡风险更高。 

Lieu教授和同事比较了青年(31岁)和老年(73岁)男性罹患9大肿瘤的数据,他们对肿瘤样本中的4500万个可疑基因进行了分析。他们发现,相比老年人的23个基因被修饰而言,青年肿瘤患者共有77个基因得以修饰。青年患者的许多修饰基因大多参与细胞增殖,且通常与癌症有关,比如ERBB2、NOTCH3、CAV1。老年患者的肿瘤相关修饰基因主要参与细胞分化与细胞增殖——例如CDX2、HMGB3、EPHB2。

研究人员试图将调查民众扩大化,同时采用临床药物测试使青年和老年结直肠癌肿瘤治疗个体化,并进一步延长肿瘤患者的生存时间,提高他们的生存质量。
