| pubmed-article:2575586 | pubmed:abstractText | Three chromosome regions, i.e., 11p15, 13q, and 17p, were previously reported by three independent groups to be specifically reduced to hemizygosity in human primary breast cancer. We examined the DNA of 64 mammary tumors for loss of heterozygosity (LOH) with 28 polymorphic DNA markers dispersed on 10 arms of 8 different chromosomes. Complete or near-complete absence of LOH was observed on 5 arms (5 chromosomes). LOH at all three previously invoked regions was confirmed, and the highest frequency was found on 17p (67% of heterozygous patients). Allele loss of a marker from chromosome 3 (region p14-p21) was found in 7 of 15 informative cases. Concurrent LOH at 2 to 4 loci was noted in 20 of the 43 tumors showing LOH. Allele losses did not correlate with any of the six clinico-histopathological variables investigated, but in a group of patients in which we were unable to demonstrate LOH, the absence of distant metastases was statistically significant (P less than 0.05). These results suggest that some of the observed allele losses reflect random events, possibly as a result of genetic instability, but are not without biological significance for the progression of particular subclasses of breast tumors. | lld:pubmed |
