In addition, we noticed an interesting, however, not statistically significant, association for rs11568821 C > T of PDCD1. Subjects carrying TT homozygotes might had more than three times higher risk of developing this NSCLC subtype compared to subjects with CC or CT genotype (TT vs. CC + CT, OR = 3.12; 95% CI = 0.88, 11.02; P = 0.084). This evidence concerns the gene PDCD1 and non-small cell lung carcinoma.
