The methylation status of seven cancer-related genes was investigated in a series of 58 colorectal cancers, 18 of which showed the microsatellite instability (MSI+) phenotype. Methylation of the hMLH1, p16 and MDR1 genes was found in 23, 29 and 28% of tumors, respectively. None of the tumors showed methylation of the TS, ATM,
PARP
or p21 genes. Methylation of the hMLH1, p16 and MDR1 genes was more frequent and more concordant in MSI+ compared to MSI- tumors (P<0.001) and was also strongly associated with poor histological differentiation (P<0.001). There were trends for associations between methylation at one or more of these loci and proximal tumor location, advanced
