Polymorphisms in the promoter regions of cytokine genes may influence prostate cancer (PC) development via regulation of the antitumor immune response and/or pathways of tumor angiogenesis. PC patients (247) and 263 controls were genotyped for interleukin (IL)-1beta-511, IL-8-251, IL-10-1082, tumor necrosis factor-alpha-308, and vascular endothelial growth factor (VEGF)-1154 single nucleotide polymorphisms. Patient control comparisons revealed that IL-8 TT and VEGF AA genotypes were decreased in patients compared with controls [23.9 versus 32.3%; P = 0.04, odds ratio (OR) = 0.66, 95% confidence interval (CI) 0.44-0.99 and 6.3 versus 12.9%; P = 0.01, OR = 0.45, 95% CI 0.24-0.86, respectively], whereas the IL-10 AA genotype was significantly increased in patients compared with controls (31.6 versus 20.6%; P = 0.01, OR = 1.78, 95% CI 1.14-2.77). Stratification according to prognostic indicators showed association between IL-8 genotype and log prostate-specific antigen level (P = 0.05). These results suggest that single nucleotide polymorphisms associated with differential production of IL-8, IL-10, and VEGF are risk factors for PC, possibly acting via their influence on angiogenesis.
