Abstract:
Studies on the relationship between ABCB1 3435C 〉 T polymorphism (rs1045642) and colorectal cancer (CRC)susceptibility have yielded inconclusive results. To clarify this issue, we undertook a meta-analysis to investigate the relationship between rs1045642 and CRC risk. Three electronic scientific publication databases (Cochrane Library, Pubmed, Embase) were screened using specific search terms. Relevant literature was identified using literature traceability methods. Selected publications were evaluated according to the inclusion and exclusion criteria. Effect size information (odds ratio and the corresponding 95% confidence interval [CI]) was obtained following quality assessment and data extraction from the included publications, and a meta-analysis conducted. Statistical analysis was performed with the Stata sofz (Version 13.0) software. Overall, 17 case-control studies involving 7129 CRC patients and 7710 healthy control subjects satisfied the criteria for inclusion in the meta-analysis. There was no significant association between ABCB1 3435C 〉 T polymorphism and CRC risk in any of the genetic models. In the CC versus CT model ( I 2 = 20.9%, P heterogeneity = .276), CC versus CT + TT model ( I 2 = 45.6%, P heterogeneity = .102) and CT versus CC + TT model ( I 2 = 17.8%, P heterogeneity = .298) analyses, between-study heterogeneities were detected as significant in Asian populations. In the CT versus TT model ( I 2 = 24%, P heterogeneity = .254) and CC + CT versus TT model ( I 2 = 0, P heterogeneity = .55), between-study heterogeneities were found to be significant in groups of different populations. The meta-analysis described here suggests that the ABCB1 3435C 〉 T polymorphism is not related to CRC susceptibility.
