Nat Med:都是肠癌也有不同 对症治疗是正道

2015-10-15 佚名 生物谷

近日,一项最新研究指出,虽然都叫结肠直肠癌(colorectal cancer),但根据生物学特性不同,结肠直肠癌可以被分为四种不同的疾病。这项研究将帮助医生根据不同的肠癌类型采取不同的治疗措施,并促进不同靶向治疗药物的开发。相关研究结果发表在国际学术期刊Nature medicine上。   这项由多个国家的科学家共同完成的研究将许多不同的结肠直肠癌研究数据汇集到一起获得了世界上

近日,一项最新研究指出,虽然都叫结肠直肠癌(colorectal cancer),但根据生物学特性不同,结肠直肠癌可以被分为四种不同的疾病。这项研究将帮助医生根据不同的肠癌类型采取不同的治疗措施,并促进不同靶向治疗药物的开发。相关研究结果发表在国际学术期刊Nature medicine上。

 
这项由多个国家的科学家共同完成的研究将许多不同的结肠直肠癌研究数据汇集到一起获得了世界上最大的结肠直肠癌数据集,并根据这些数据对肠癌亚型进行了分类。
 
该项研究整合了世界范围内3443名肠癌病人的数据,其中包括了许多如基因突变,基因活性,免疫系统激活,细胞代谢,癌细胞类型以及向周围组织侵袭能力的分子学和临床数据。他们通过结合各种参数开发了数学算法,并以此对肠癌亚型进行了分组,提高了之前基于小数据集进行的疾病类型分类的准确度。
 
研究人员发现有大约87%的肠癌归属于四个亚型中的一种,而这四种具有不同分子特征的肠癌亚型,每一种都具有自身独特特征,使得它们对于相同治疗策略具有不同的应答情况。
 
其中一种类型的肠癌通常获得诊断较晚(III期和IV期),并且这类肠癌具有高转移能力,相比于其它类型的肠癌,病人生存率也更差。而对于另外一种类型的肠癌亚型来说,即使出现复发情况,病人的生存率也会更高。
 
研究人员指出,这项研究鉴定出了四种不同类型的肠癌,每一种都具有特定的遗传和生物学特性,并且其中一些类型更具侵袭性也更加致命,这会帮助医生找出病情更加恶劣的病人,并进行相应治疗,同时这项研究也会促进新的分子诊断检测方法的开发,用以区分不同的肠癌亚型,并帮助病人选择合理有效的治疗手段。
