0.040 GeneticVariation BEFREE The results of meta-analysis: the PDCD-1.5 (rs2227981) and PDCD-1.3 (rs11568821) polymorphisms were associated with decreased risk of cancer (rs2227981: OR = 0.75, 95% CI: 0.64-0.86, P < 0.0001 for TT vs TC + CC; rs11568821: OR = 0.79, 95% CI: 0.65-0.96, P = 0.02 for TC vs TT), while no significant associations were found for the other 3 polymorphisms (PDCD-1.9 [rs2227982] polymorphism: OR = 1.03, 95% CI: 0.90-1.18, P = 0.66 for CC + TC vs TT; PDCD1 rs7421861 polymorphism: OR = 1.10, 95% CI: 0.96-1.25, P = 0.16 for CC + TC vs TT; PDCD-1.6 [rs10204525] polymorphism: OR = 0.93, 95% CI: 0.82-1.05, P = 0.24 for GG + GA vs AA). 27749524
