    • IHC image of CSB-RA548583A0HU diluted at 1:100 and staining in paraffin-embedded human prostate tissue performed on a Leica BondTM system. After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4°C overnight. The primary is detected by a Goat anti-rabbit IgG polymer labeled by HRP and visualized using 0.05% DAB.

    4. Differences in fPSA-recovery between all investigated assays were even more pronounced. When applying the tPSA cutoff of 3.1 mug/L recommended for WHO-calibrated assays, the use of higher calibrated assays may lead to unnecessary prostate biopsies.

    8. The prepared biosensor can assay from 0 to 500ng/mL of prostate specific antigen (PSA) level within 2h with the detection limit of 1.18ng/mL by the measurement of resistance change.

    10. The 12-week PSA response rate was 88% (22/25) and 22% (4/18), median time to PSA progression was 18.2 months [95% confidence interval (CI), 8.3 months-not reached) and 3.7 months (95% CI, 2.8-5.6 months), and median time on treatment 21 months (range, 2.6-37.5) and 4.9 months (range, 1.3-23.2), for the AAP-naive and post-AAP cohorts, respectively.

    16. As restaging in advanced prostate cancer patients is often guided by increases in PSA levels, our results demonstrate that disease progression on enzalutamide can occur without rising PSA levels. Therefore, a disease monitoring strategy that includes imaging not entirely reliant on serial serum PSA measurement may more accurately identify disease progression. PMID: 28117385
    17. Older men who underwent no PSA testing or incomplete testing were significantly more likely to be diagnosed with high-risk prostate cancer than those who were previously screened. It is reasonable to consider screening in healthy older men likely to benefit from early detection and treatment. PMID: 28045113

    21. Microenvironmental acidity determines qualitatively and quantitatively the release of extracellular vesicles by malignant prostate tumors.

    34. Extended follow-up of the PLCO trial over a median of 15 years continues to indicate no reduction in prostate cancer mortality for the intervention arm versus the control arm. Because of the high rate of control-arm PSA testing, this finding can be viewed as showing no benefit of organized screening versus opportunistic screening PMID: 27911486
