Background/Objective: It has been reported that Krüppel like factor 6 intervening sequence (KLF6 IVS) 1-27 G > A might be associated with cancer susceptibility. Here, we conducted a meta-analysis to summarize and clarify this association. Materials and Methods/Main Results: A systematic search of studies on the association between KLF6 IVS 1-27 G > A, and cancer susceptibility was conducted in databases. Odds ratios and 95% confidence intervals were used to pool the effect size. Seven articles were included in our meta-analysis. Overall and in prostate cancer, population-based subgroup overall and Caucasian subgroup overall, no evidence was found for the association between KLF6 IVS 1-27 G > A polymorphism and cancer susceptibility in any genetic model and the results showed stability in sensitivity analyses. Conclusions: KLF6 IVS 1-27 G > A may not be associated with cancer susceptibility, especially the susceptibility of unselected prostate cancer. However, there was insufficient data to fully confirm the association between KLF6 IVS 1-27 G > A and familial prostate cancer, sporadic prostate cancer, gastric cancer, and cancers from different ethnicity, and the results should be interpreted with caution.
