- Abstract
Purpose: Evidence is accumulating indicating that chronic inflammation plays an important role in prostate cancer. We investigated the potential prognostic roles of IL-6, IL-8 and IL-10 polymorphisms in clinical localized prostate cancer after radical prostatectomy. Materials and Methods: A total of 116 clinically localized prostate cancer patients undergoing curative radical prostatectomy were included in this study. The IL-6, IL-8 and IL-10 polymorphisms were determined by the TaqMan real-time PCR method. Their prognostic significance on prostate-specific antigen (PSA) recurrence was assessed using Kaplan-Meier analysis and Cox regression model. Results: The IL-6 polymorphism (rs2066992) T/G and G/G genotype cases were associated with a higher percentage of preoperative PSA levels of ≥10 ng/ml; higher risk of positive surgical margin, and higher risk of extraprostatic extension compared to the T/T genotype. The IL-10 polymorphism (rs1800871) A/A genotype was associated with a higher risk of PSA recurrence compared with the A/G + G/G genotypes and significantly poorer PSA-free survival (log-rank test, p = 0.019). After considering other covariates in a Cox proportional hazard model, the IL-10A/A genotype and high Gleason score (8–10) were still independent predictors of poor PSA-free survival. Conclusion: Our results suggest that the IL-10 polymorphism may be a prognostic factor for PSA recurrence after radical prostatectomy. Copyright © 2009 S. Karger AG, Basel
