The purpose of this study was to conduct a meta-analysis to assess the association between FSHR Asn680Ser polymorphism and ovarian cancer susceptibility.
A literature search was conducted in PubMed, Embase and the China National Knowledge Infrastructure (CNKI) for all relevant studies published up to September 2013. The pooled odds ratios (ORs) with the corresponding 95 % confidence intervals (95 % CIs) were calculated to evaluate the association.
Four case-control studies including 474 ovarian cancer cases and 659 controls met the inclusion criteria. The pooled analyses showed that FSHR Asn680Ser polymorphism was associated with the risk of ovarian cancer (Ser vs Asn: OR=1.295, 95 % CI 1.057-1.498, P=0.01; Ser/Ser + Asn/Ser vs Asn/Asn: OR=1.611, 95 % CI 1.027-2.528, P=0.038). Subgroup analyses by ethnicity (Caucasian and Asian) further revealed significant associations among Asians (Ser vs Asn: OR=1.386, 95 % CI 1.066-1.802, P=0.015; Ser/Ser + Asn/Ser vs Asn/Asn: OR=1.893, 95 % CI 1.329-2.689, P=0.000) but not Caucasians. There was no obvious risk of publication bias.
The meta-analysis suggests that FSHR Asn680Ser polymorphism may be a risk factor for ovarian cancer in Asians. Due to the limited quantity of the included studies, further studies are needed to validate the above conclusions.
本研究旨在进行一项荟萃分析,以评估促卵泡激素受体(FSHR)Asn680Ser多态性与卵巢癌易感性之间的关联。
在PubMed、Embase和中国知网(CNKI)中检索截至2013年9月发表的所有相关研究。计算合并优势比(OR)及相应的95%置信区间(95%CI)以评估关联性。
四项病例对照研究(包括474例卵巢癌病例和659例对照)符合纳入标准。汇总分析表明,FSHR Asn680Ser多态性与卵巢癌风险相关(Ser与Asn相比:OR = 1.295,95%CI 1.057 - 1.498,P = 0.01;Ser/Ser + Asn/Ser与Asn/Asn相比:OR = 1.611,95%CI 1.027 - 2.528,P = 0.038)。按种族(白种人和亚洲人)进行的亚组分析进一步显示,亚洲人之间存在显著关联(Ser与Asn相比:OR = 1.386,95%CI 1.066 - 1.802,P = 0.015;Ser/Ser + Asn/Ser与Asn/Asn相比:OR = 1.893,95%CI 1.329 - 2.689,P = 0.000),而白种人则不然。没有明显的发表偏倚风险。
荟萃分析表明,FSHR Asn680Ser多态性可能是亚洲人患卵巢癌的一个风险因素。由于纳入研究数量有限,需要进一步研究来验证上述结论。
