A case-control study of 401 cases and 300 sex- and age-matched controls was performed in order to explore the role of IL1B_1473G/C (rs1143623), SOD1_7958A/G (rs4998557), TLR4_1196C/T (rs4986791), IL10_1082A/G (rs1800896), IL17A_197G/A (rs2275913), and TLR4_896A/G (rs4986790) polymorphisms in the susceptibility to colorectal cancer (n = 244), gastric carcinoma (n = 72), and ovarian cancer (n = 85).
Our study suggests that variant TLR4 (Asp299Gly and Thr399Ile alleles) as well as TLR2 (Arg753Gln allele) are not associated with risk of colorectal cancer.
These findings indicated that the polymorphism of CD14 but not TLR4 Asp299Gly mutation was associated with Chinese patients with colorectal cancer, and the CD14 gene may contribute to the predisposition to colorectal cancer.
