dc.description.abstract | Background/Aims: This study was designed to determine the prevalence of microsatellite instability (MSI) among colorectal adenomas detected in patients <= 40 years of age and to compare the prevalence of MSI in young (<= 40 years) and older (>40 years) patients with colorectal adenomas. Additionally, we attempted to identify the underlying cause of MSI in these patients. Methodology: We prospectively tested for the presence of MSI using five NCI markers in samples from the two patient groups. The frequency of MSI was compared and the underlying causes of MSI were determined by methylation specific PCR and germ-line mutation analysis for mismatch repair genes. Results: The frequency of MSI was higher in the <= 40 group than the >40 group (31.4% and 6.4%, respectively, p=0.0004). The MSI-high pattern was also more prevalent in the <= 40 group than the >40 group (15.7% and 2.5%, respectively, p=0.01.4). The hypermethylated hMLH1 gene was demonstrated in 7/8 (87.5%) patients with MSI-high in the <= 40 group and in 1/2 (50.0%) patients with MSI-high in the >40 group. No study subject showed a germline mutation of hMLH1 or hMSH2. Conclusions: MSI-high was more frequent in young (<= 40 years) patients with colorectal adenoma than in older (>40 years) patients. Hypermethylation of the hMLH1 gene appears to be an important cause of MSI-high in these patients. | - |
