To evaluate the role of peripheral inflammation (leukocyte differential count, the proinflammatory cytokines IL-beta, TNF-α, IL-6, IL-8, and the inflammatory markers fibrinogen and C-reactive protein [CRP]) in frailty syndrome in patients with prostate cancer (CaP) undergoing antiandrogen therapy (ADT).
Altogether, our data reveal a clear association between the presence of MetS, a greater number of MetS-components or CRP levels >2.5 mg/L with an increased Sig-PCa diagnosis and/or with aggressive features, suggesting that MetS and/or CRP levels might influence PCa pathophysiology.
Multivariable Cox proportional hazard regression models were used to study whether individual biomarkers (WBC, hs-CRP), a combined score based on analyte tertiles (score range 2-6), or change in CRP were associated with risk and severity of prostate cancer.
Serum CRP levels were associated with increased odds of high risk and metastatic PCa, and high PSA levels (≥20 µg/L) (OR: 1.29; 95% CI: 1.06-1.56, 1.32; 1.05-1.65 and 1.51; 1.26-1.81, respectively).
Individuals with one copy of the minor allele (C) in rs1800947 had an increased risk of high-grade prostate cancer (OR: 1.7; 95% CI: 1.1-2.8), and significantly lower mean CRP levels (P-value <0.001), however, we found no significant association with lethal disease.
Though neither IL-6 nor CRP was associated with prostate cancer incidence overall, we observed a statistically significant interaction between IL-6 and BMI on prostate cancer incidence (p(interaction) < 0.01).
SNPs at the CRP locus are not associated with PCa risk in this cohort, while the association between rs1800795 and PCa risk warrants further investigation.
Ectopic expression of a partial sequence of PTX1 (Met84 - Leu225) as a VP22-fusion protein in prostate cancer cell line, PC-3, induced cellular senescence.
The aim of this study was to examine whether C-reactive protein (CRP) levels and CRP gene variations were associated with an altered risk of colorectal, lung, breast, or prostate cancer.
