Association between STAT3 rs1053004 polymorphism and cancer risk: a meta-analysis.

Several studies examined the relationship between STAT3 rs1053004 polymorphism and the risk of some human cancers, but the findings remains inconclusive. To evaluate the impact of STAT3 rs1053004 on cancer risk, we conducted a meta-analysis of all available studies including 4,605 cancer cases and 5,248 controls. Eligible studies were identified by searching PubMed, Web of Science, Scopus, and Google scholar databases. Pooled odds ratios (ORs) with 95% confidence intervals (CIs) were calculated in codominant, dominant, recessive, overdominant, and allele models to quantitatively estimate the association. The overall findings showed no significant association between STAT3 rs1053004 polymorphism and cancer risk in codominant, dominant, recessive, overdominant, and allele inheritance model tested. In summary, the findings of this meta-analysis indicates no significant association between STAT3 rs1053004 polymorphism and cancer development. Larger and well-designed studies are necessary to estimate this association in detail.
