Abstract

Cyclooxygenase-2 (COX-2), an inducible isoform of cyclooxygenase, has been reported to be correlated with tumorigenesis, tumor progression, and metastasis. We aimed to evaluate the association between COX-2 (rs2745557) polymorphism and prostate cancer (PCa), benign prostate hyperplasia (BPH) risk. We also assessed the influence of other risk factors such as obesity, smoking, diabetes in modulating the risk of PCa in Egyptian men. COX-2 (rs2745557) was genotyped in 112 PC patients, 111 BPH and 120 subjects as a control group. COX-2 and PSA levels were measured by ELISA. We found that GG genotype was associated with a 17-fold increased risk for PCa and 20-fold increased the risk for BPH more than AA genotype. Also, G allele carriers of COX-2 were associated with metastatic cancer (OR = 1.3, P < 0.05) and disease aggressiveness (OR = 3.5, P < 0.001). The coexistence of obesity, smoking, or diabetes with GG genotype may lead to increasing the risk of developing BPH (OR = 3.3, 4, and 2.7, respectively) and of developing PCa (OR = 2.9, 4.9, and 3.2, respectively). Our results showed evidence suggesting the involvement of the COX-2 (rs2745557) polymorphism and its protein in PCa or BPH initiation and progression. Also, the coexistence of COX-2 (rs2745557) and obesity, smoking, or diabetes may lead to the development of PCa or BPH.
