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 (OR=2.46 95% CI 1.20-5.06; P=0.015). Furthermore, we found that carriers of Gln751Gln XPD genotype have an increased susceptibility of ovarian cancer (OR=3.40 95% CI 1.61-7.15; P=0.001). 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.
本研究的目的是评估XPD基因分型作为卵巢癌易感性遗传指标的作用。我们采用了病例对照研究。我们使用聚合酶链反应-限制性片段长度多态性(PCR-RFLP)分析了141例卵巢癌患者和202例对照者的DNA样本,检测三种XPD基因多态性。我们观察到Asn312Asn XPD基因分型携带者患卵巢癌的易感性增加(比值比=2.46,95%置信区间1.20-5.06;P=0.015)。此外,我们发现Gln751Gln XPD基因分型携带者患卵巢癌的易感性增加(比值比=3.40,95%置信区间1.61-7.15;P=0.001)。Asn312Asn和Gln751Gln尤其与疾病的早期阶段相关。我们的结果表明Asn312Asn和Gln751Gln XPD基因多态性在卵巢癌易感性中起重要作用。
