Analyze association of the progesterone receptor gene polymorphism PROGINS with ovarian cancer risk.
Results conflict on the association between progesterone receptor gene (PRG) polymorphism PROGINS and ovarian cancer risk, despite wide-ranging investigations. We therefore performed a meta-analysis of 4,285 ovarian cancer cases and 6,257 controls from 11 published case-control studies. The strength of association between PROGINS polymorphism and ovarian cancer susceptibility was assessed using pooled odds ratios (ORs) with corresponding 95 % confidence intervals (CIs). The results suggest no significant associations exist between PROGINS polymorphisms and ovarian cancer risk in overall comparisons in all genetic models (T2T2 vs. T1T1: OR = 1.37, 95 % CI = 0.89-2.12, P = 0.15; T1T2 vs. T1T1:OR = 1.09, 95 % CI = 0.88-1.35, P = 0.41; T1T2 + T2T2 vs. T1T1:OR = 1.15, 95 % CI = 0.94-1.40, P = 0.17; T2T2 vs. T1 T1 + T1T2:OR = 1.34, 95 % CI = 0.87-2.07, P = 0.18). In conclusion, the results of this meta-analysis indicate that the PRG polymorphism PROGINS is not associated with ovarian cancer risk when multiple ethnic groups or regions were considered overall.
