title: Frequency of CYP1B1 homozygous genotype 355T/T in prostate cancer families from Poland.
abstract: A group of 98 families were analyzed for CYP1B1 gene 355T/T homozygous genotype frequency because of prostate cancer history. Molecular investigations were performed using the restriction fragment length polymorphism-PCR method. 355T/T genotype was detected in 14 of the 98 prostate cancer patients (14.3%). Among them, it was found in one man (7.1%) from a family suspected of hereditary prostate cancer (his age at prostate cancer diagnosis was 57 years) and in 13 men (92.9%) originating from families that did not strictly fulfill hereditary prostate cancer criteria (the median age at prostate cancer diagnosis was 60.1 years). Among 14 355T/T genotype-positive families, in 10 (71.4%) other types of cancers, for example, breast, uterus, stomach, colon, ovary, lung, larynx, bladder, pancreas and melanoma other than prostate cancer, were present, and in four (28.6%) only one cancer type, that is, prostate cancer, occurred. In the Polish population, the CYP1B1 355T/T genotype seems to be associated with prostate cancer; the frequency of this genotype was 5.9% higher in prostate cancer patients than in the general population (8.4%). However, it is not associated with prostate cancer family history.
