Association analysis between 8-oxoguanine DNA glycosylase genetic variants and endometrial cancer susceptibility in Chinese Han population

Association of the hOGG1 Ser326Cys polymorphism with gynecologic cancer susceptibility: a meta-analysis

The association between the hOGG1 Ser326Cys polymorphism and gynecologic cancer susceptibility is inconclusive. We performed a comprehensive meta-analysis to precisely estimate of the impact of the hOGG1 Ser326Cys polymorphism on gynecologic cancer susceptibility. Electronic databases including PubMed, Embase, WanFang, and the China National Knowledge Infrastructure were searched for relevant studies. Odds ratios (ORs) with corresponding 95% confidence intervals (CIs) were determined to assess the strength of the association. Fourteen studies with 2712 cases and 3638 controls were included in the final meta-analysis. The pooled analysis yielded a significant association between the hOGG1 Ser326Cys polymorphism and overall gynecologic cancer susceptibility (dominant model: OR = 1.16, 95% CI = 1.03–1.30, P=0.017). A significantly higher gynecologic cancer risk was found for the European population (homozygous model: OR = 2.17, 95% CI = 1.80–2.61, P<0.001; recessive model: OR = 2.11, 95% CI = 1.41–3.17, P<0.001; dominant model: OR = 1.29, 95% CI = 1.12–1.48, P<0.001; and allele model: OR = 1.40, 95% CI = 1.13–1.74, P=0.002), but not in the Asian population. The stratified analysis by cancer type revealed endometrial cancer was significantly associated with the hOGG1 Ser326Cys polymorphism (dominant model: OR = 1.29, 95% CI = 1.09–1.54, P=0.003; and allele model: OR = 1.28, 95% CI = 1.02–1.60, P=0.031). In conclusion, the hOGG1 Ser326Cys polymorphism was associated with higher overall gynecologic cancer susceptibility, especially for endometrial cancer in the European population.

Endometrial carcinoma-related genetic factors: application to research and clinical practice in China

Genetic factors affect the initiation and progression of endometrial carcinoma (EC). The routine detection of genetic factors involved in EC has not been extensively performed in Chinese clinical practice, however. In this review we summarise EC-related genetic factors, including Lynch syndrome-associated mutations and non-Lynch syndrome-associated genetic predispositions found in Chinese women, and their potential clinical applications. In addition, we propose a clinical testing strategy for patients with EC and their family members. The objective of this review is to advance basic research regarding the genetic factors involved in EC and to improve its clinical implementation in China.

TWEETABLE ABSTRACT

Review summarises Chinese research progression of EC-related genetic factors and proposes innovative screening strategy.
