UNLABELLED: The aim of this study was to evaluate the association of polymorphic genotypes in the cyclooxygenase 2 gene (COX2), which is reported to be overexpressed in prostate tumors, with Taiwan prostate cancer patients. MATERIALS AND METHODS: Six polymorphic variants of COX2 were analyzed for their association with prostate cancer susceptibility. A total of 218 patients with prostate cancer and 436 healthy controls in central Taiwan were enrolled in this investigation. P-values and odds ratios with 95% confidence intervals were used to assess the strength of the association. RESULTS: Among the six polymorphic sites examined, only the Cox-2 promoter G-765C (rs14133) genotypes were distributed differently between the prostate cancer and control groups. The COX2 -765GG genotype was associated with higher prostate cancer risk than -765GC. CONCLUSION: These findings provide evidence that the G allele of COX2 promoter G-765C may be associated with the development of prostate cancer and may be a useful marker for early detection of prostate cancer.
