IL10 and breast carcinoma: We found that the ins/del and del/del genotypes of NFKB1 polymorphism and TT genotype of IL-10 polymorphism significantly increased breast cancer risk (NFKB1 ins/del odds ratio [OR] 1.69, 95% [CI] 1.23-2.33, P = 0.001; NFKB1 del/del OR 2.42, 95% CI 1.72-3.42, P < 0.001; IL-10 TT OR 2.36, 95% CI 1.58-3.52, P < 0.001).
