BCL2 and nasopharyngeal carcinoma: Similarly, a significant correlation between BCL2 -938 C>A polymorphism and NPC was found in the genotype CA, AA, CA+AA and the allele A [CA: (OR= 2.26, 95% CI= 1.03, 4.96, P= 0.04); AA: (OR= 3.56, 95% CI= 0.97, 13.05, P= 0.05); CA+AA: (OR=3.10, 95% CI= 1.51, 6.35, P=0.002); A: (OR=2.90, 95% CI= 1.59, 5.29, P=0.0005)].
