Abstract

A group of sporadic breast carcinomas, with no alteration in TP53 locus, were analysed for the presence of LOH in 17p13.3, distinct from and telomeric to TP53. LOH by at least one marker were observed in 13 of 47 informative cases (27,6%). Clinico-pathological parameters of the patients were evaluated. LOH at distal 17p13.3 did significantly correlate with the absence of oestrogen receptors (ER) (P=0.018), progesterone receptors (PgR) (P= 0.009) and concordant absence of either ER or PgR (P=0.006). This may provide a basis for speculation as to the function of the putative tumour suppressor genes in 17p13.pter in sporadic breast cancer.
