Frequent microsatellite alterations in a predominantly younger age of onset breast cancer population.

Abstract:

:Microsatellite instability (MSI) and loss of heterozygosity (LOH) was investigated in paired tumour and normal tissue DNA from 108 predominantly premenopausal breast cancer patients (under age 45 years at presentation) for 25 simple repeat loci interspersed across 11 chromosomes. MSI was observed at a single locus in 69 (64%) patients; 41 of these had instability at more than one site. Greatest frequency of MSI was at loci D2S1356 (33%), D2S2739 (22%), D3S1766 (21%) and D13S796 (20%). LOH was seen at a single site in 55% of patients and at two or more sites in 27 patients with greatest frequency at D2S1356 (33%), D2S443 (19%) and D17S1299 (18%). Both mutations were found in the same patient but at different loci. Clearly, choice of loci is a determining factor in assessing genomic instability. The relatively high frequency of MSI may also reflect peculiarities of this younger patient population. Occurrence of MSI or LOH was unrelated to clinical stage, nodal status, tumour size or grade or steroid receptor status. It was independent of mutations detected in exons 5-9 of the p53 gene. There was no significant association with survival. The lack of such correlations reflects a random disabling mechanism that may equally affect genes promoting cell death as well as growth.
