Relationship between the p27Kip1 (here after referred to as p27) V109G polymorphism and cancer risk has been extensively studied; however, results from different studies were not fully consistent. Therefore, we carried out a meta-analysis to comprehensively assess the correlation between the p27V109G polymorphism and the cancer risk. Articles on the relationship of the p27V109G polymorphism with cancer risk were searched from Medline, Pub Med, and Web of science databases. A total of eight eligible studies with 3591 cases and 3799 controls were included in this meta-analysis. Overall, it seemed that the G allele was not associated with the elevated cancer risk (pooled odds ratio [OR]=0.98, 95% confidence interval [CI]: 0.88-1.09, p=0.68, fixed effects). Analyses in different populations revealed that no statistically significant associations between the G allele and cancer risk were demonstrated in Caucasians or Asians. When analyzed in different types of cancer that, from two studies, the G allele was found to be associated with a decreased risk of prostate cancer in a dominant genetic model (pooled OR=0.60, 95% CI=0.36-0.98, p=0.04, fixed effects), but did not alter the breast cancer risk from four studies. In conclusion, this meta-analysis indicated that the p27V109G polymorphism did not correlate with the overall cancer risk in the general population.
