Background/Aim:
Inflammation plays an important role in prostate cancer (PCa). We evaluated proinflammatory cytokines regarding differential diagnosis of PCa in men with PSA levels between 2-10 ng/ml.
Patients And Methods:
Serum samples of 79 men (PSA 2-10 ng/ml) were analyzed for 10 proinflammatory cytokines (IL-6, IL-8, TNF-α, IFN-γ, IL-10, IL-1β, IL-2, IL-4, IL-12p70, IL-13) and results were evaluated regarding presence of PCa and disease severity.
Results:
Significant differences between PCa patients and controls were found for IL-6 (p=0.002), IL-8 (p=0.030), and TNF-α (p=0.009), although they were not predictors of PCa in a logistic regression analysis. In addition, IL-6 and TNF-α levels were significantly higher in patients with high-risk PCa (p<0.05). No significant differences were observed regarding the other cytokines.
Conclusion:
In patients with PSA levels between 2-10 ng/ml, IL-6, IL-8, and TNF-α are associated with PCa, and IL-6 and TNF-α are associated with high-risk PCa.
