Quantitative assessment of the relationship between Fas/FasL genes polymorphisms and head and neck cancer risk.
Ontology highlight
ABSTRACT: Molecular epidemiological studies have demonstrated a closer association between Fas/FasL polymorphisms and head and neck cancer (HNC) risk, and the results of these published studies were inconsistent. We therefore performed this meta-analysis to explore the associations between Fas/FasL polymorphisms and HNC risk.Four online databases (PubMed, Embase, CNKI, and Wanfang) were searched. Odds ratios (ORs) with 95% confidence interval (95% CIs) were calculated to assess the association between Fas -670A>G, Fas -1377G>A, and FasL -844C>T polymorphisms and HNC risk. In addition, heterogeneity, accumulative/sensitivity analysis, and publication bias were conducted to check the statistical power.Overall, 9 related publications (20 independent case-control studies) involving 3179 patients and 4217 controls were identified. Significant association of protective effects was observed between FasL -844C>T polymorphism and HNC risk in codominant and dominant model models (CT vs CC: OR?=?0.89, 95% CI?=?0.79-1.00, P?=?.05, I?=?38.3%, CT+TT vs CC: OR?=?0.88, 95% CI?=?0.79-0.98, P?=?.02, I?=?35.8%). Furthermore, the similar protective effects were observed the subgroup analysis of in Asian population and population-based controls group.Our meta-analysis indicated that FasL -844C>T polymorphism plays a protective role against HNC development, but the Fas -670A>G and Fas -1377G>A polymorphisms maybe not associated with HNC risk.
