27 Oct 2012
Abstract excerpt
Approximately 30% of colorectal carcinomas develop via a serrated neoplasia pathway, named for the pattern of crypts in the precursor polyps. Molecular abnormalities consistently involve methylation of CpG islands [CpG island methylator phenotype (CIMP)] of low degree (CIMP-L) or high degree (CIMP-H), and activating mutations of the mitogen-activated protein kinase pathway components BRAF or KRAS.
