摘要
结直肠癌是最常见的恶性肿瘤之一,其发生发展是环境和遗传因素共同作用的结果,其中遗传因素在结直肠癌的发病中起重要作用。全基因组关联研究(genome-wide association studies,GWAS)已发现了一些与结直肠癌相关联的易感位点和区域,这有助于结直肠癌遗传机制的研究。文中对近几年来结直肠癌全基因组关联分析的研究进展作一综述,分析GWAS结直肠癌的优点和局限性以及应用前景。
Colorectal cancer (CRC) , one of the most common malignant tumors, is caused both by environmental and genetic factors. Genetic factor plays an important role in the pathogenesis of CRC. Genome-wide association study (GWAS) is a new tool of genetic research. A series of susceptibility genes and loci of the complex diseases has been identified with GWAS strategy. In this article, the research progress on GWAS of CRC is reviewed, and the advantages and limitations of GWAS study as well as the prospective of its application are discussed.
