Colorectal cancer (CRC) is a leading cause of cancer deaths worldwide. Over the past three decades, extensive efforts have sought to elucidate the genomic landscape of CRC. These studies reveal that CRC is highly heterogeneous at the molecular level, with different subtypes characterised by distinct somatic mutational profiles, epigenetic aberrations and transcriptomic signatures. This review summarises our current understanding of the genomic and epigenomic alterations implicated in CRC development and progression. Particular focus is given to how characterisation of CRC genomes is leading to more personalised approaches to diagnosis and treatment.
结直肠癌(CRC)是全球癌症死亡的主要原因。在过去的三十年中,人们进行了广泛的努力来阐明 CRC 的基因组图谱。这些研究表明,CRC 在分子水平上具有高度异质性,不同的亚型具有不同的体细胞突变谱、表观遗传异常和转录组特征。本文综述了我们目前对 CRC 发生和发展中涉及的基因组和表观基因组改变的理解。特别关注的是如何对 CRC 基因组进行特征描述,从而为诊断和治疗提供更具个性化的方法。
