Abstract excerpt
CONTEXT: The 2 chief pathways implicated in colorectal carcinogenesis, microsatellite instability and chromosomal instability, are not present in 20% to 37% of cases. OBJECTIVE: To determine whether the CpG island methylator phenotype (CIMP) pathway, characterized by simultaneous methylation of several known tumor suppressor genes, is the principal underlying mechanism in cases without chromosomal or...
