BackgroundCaveolin-1 (CAV1) is an essential structural component of caveolae, regulates cellular processes through complex cellular signaling pathways, and influences tumorigenicity. However, the role of the CAV1 (rs7804372) polymorphism in digestive cancers remains inconclusive. The meta-analysis was performed to evaluate the effect of CAV1 polymorphism on digestive cancer susceptibility and to provide a basis for precise treatment.MethodsThe databases of PubMed, EMBASE, Google Scholar and CNKI were used to retrieve the published studies on CAV1 (rs7804372) polymorphism and susceptibility to digestive cancers up to June 2020. Two researchers conducted study screening, data extraction, and methodological quality evaluation separately according to inclusion and exclusion criteria. Review Manager 5.3 software was used to conduct the meta-analysis.ResultsSix case-control studies were enrolled, including 2477 patients with digestive cancers and 2477 healthy controls. The pooled results showed that the CAV1 rs7804372 (T29107A) polymorphism increased the risk of digestive cancer occurrence in the allele (T vs. A: odds ratio (OR) 1.33, 95% confidence interval (CI): 1.15-1.53, P < .01), homozygous (TT vs. AA: OR 1.72, 95% CI: 1.31-2.26, P < .01), heterozygous (TA vs. AA: OR 1.47, 95% CI: 1.21-1.78, P < .01), dominant (TT vs. TA + AA: OR 1.32, 95% CI: 1.18-1.48, P < .01), and recessive comparing models (TT + TA vs. AA: OR 1.61, 95% CI: 1.26-2.07, P < .01).ConclusionOur results indicate that the CAV1 (rs7804372) polymorphism may modify the occurrence of digestive cancers, and the presence of T allele or TT genotype of the CAV1 (rs7804372) may increase the risk of digestive cancers.Copyright © 2021 the Author(s).
