Abstract

Secreted group IIA phospholipase A2 (sPLA2-IIA) is markedly up-regulated in human prostate cancer (PCa) specimens and in some PCa-derived cell lines, indicating an important role of this enzyme in tumourigenesis. In this study, we measured levels of sPLA2-IIA, C-reactive protein (CRP), and prostate-specific antigen (PSA) in serum samples obtained from patients with benign prostatic hyperplasia (BPH) and with PCa of different stages. We found that serum levels of sPLA2-IIA and CRP in BPH and PCa patients were significantly elevated compared to those of healthy individuals, but the concentrations of these inflammatory biomarkers did not differ between patients with BPH or PCa. Furthermore, serum levels of sPLA2-IIA correlated with concentrations of CRP, but not with PSA, Gleason grade or tumour stage. In conclusion, these findings suggest that cancer-related changes are not exclusive factors contributing to elevated serum sPLA2-IIA levels and emphasize the utility of sPLA2-IIA as a circulating marker of inflammation in patients with BPH and PCa.

WHO estimates that half of all patients worldwide are non-adherent to their prescribed medication. The consequences of poor adherence can be catastrophic, on both the individual and population level.

Join our expert panel to discover why you need to understand the drivers of non-adherence in your patients, and how you can optimize medication adherence in your clinics to drastically improve patient outcomes.
