Descrição

The purpose of this study was to evaluate the role of XPD genotypes as genetic indicator of susceptibility to ovarian cancer. We have used a case–control study. We analysed DNA samples from 141 ovarian cancer patients and 202 control subjects, for three XPD polymorphisms using PCR-RFLP. We observed that Asn312Asn XPD genotype carriers have increased susceptibility of ovarian cancer (ORZ2.46 95% CI 1.20–5.06; PZ0.015). Furthermore, we found that carriers of Gln751Gln XPD genotype have an increased susceptibility of ovarian cancer (ORZ3.40 95% CI 1.61–7.15; PZ0.001). Asn312Asn and Gln751Gln are particularly associated with an early-stage of disease. Our results suggest an important role for Asn312Asn and Gln751Gln XPD polymorphisms in the susceptibility to ovarian cancer.
