Association of breast cancer progression with a vitamin D receptor gene polymorphism. South-East Sweden Breast Cancer Group.

The vitamin D3 receptor gene ( VDR) contains a TaqI RFLP that is associated with increased VDR mRNA stability, increased serum levels of 1alpha,25-dihydroxyvitamin D3 (1,25-D3), and decreased risk for prostate cancer. Determination of the TaqI genotype, in a group of young women with breast cancer (n = 111; age, <37 years) and a control population (n = 130), revealed no overall association to risk for breast cancer. However, patients without TaqI site (TT genotype) showed a significantly increased risk for lymph node metastasis (relative risk, 1.8, 95% confidence interval, 1.3-2.6). Furthermore, a tendency toward an increased survival was found among estrogen receptor-positive, tamoxifen-treated patients who were homozygous for the TaqI site (P = 0.075). We conclude that polymorphism in the VDR gene may influence tumor progression and tamoxifen treatment response in early-onset breast carcinomas.[1]
