    Abstract: 57 Background: US-MRI fusion biopsy (FB) showed that it improves the detection of clinically significant prostate cancer (PCa). A more accurate diagnostic method is desirable to avoid misclassification, which in turn is particularly important in appropriate decision making on treatment for PCa (active surveillance or focal therapy or radical treatment). We aimed to compare the Gleason upgrading (GU) rates and the concordance of the Gleason scores in the biopsy versus final pathology after the surgery in patients who underwent only TRUS systematic random biopsies versus US-MRI FB for PCa. Methods: A retrospective analysis of patients’ prospective collected data that underwent prostate biopsy and subsequent radical prostatectomy were included from January 2011 to June 2016 at our institution. The study cohort was divided into: US-MRI FB (Group A) and only TRUS systematic random biopsy (Group B). US-MRI FB was performed in patients who had a previous MRI with a focal lesion classified by Likert score ≥ 3, otherwise a TRUS systematic random biopsy was performed. All biopsies and surgical specimens were analyzed by the same uropathologist and MRIs were analyzed by two expert urological radiologists. Results: 73 men underwent US-MRI FB and 89 TRUS systematic random biopsy. The GU rate was higher in group B (31.5% vs 16.4%; p = 0.027). GU according to Gleason grade pattern was higher in Group B against Group A (40.4% vs 23.3%; p = 0.02). Analyses from separate Gleason grade pattern showed that Gleason score 3+4 presented less GU in group A (24.1% vs 52.6%; p = 0.043). The Bland-Altman plot analysis showed a higher bias in Group B compared to group A (-0.27 [-1.40 to 0.86] vs -0.01 [-1.42 to 1.39] ). In the multivariable logistic regression the only independent predictor of GU was the use of TRUS systematic random biopsy (2.64 [1.11 – 6.28]; p = 0.024). Conclusions: The US-MRI FB appears to be related to a decrease in GU rate and an increase in the concordance between biopsy and final pathology in comparison to TRUS random biopsy, that leads to greater accuracy on diagnosis and better treatment decision.

    Cell-free plasma DNA for the diagnosis and follow-up of prostate cancer patients.

    Abstract: e16058 Background: Cell free plasma DNA (CF–pDNA) may have diagnostic and prognostic value in patients with Prostate Cancer (PCa). Methods: We included 133 men with PCa and 33 controls. PCa patients had blood drawn every 3 months for 2 years. CFpDNA was measured by spectrophotometry. Results: CF-pDNA had an area under the curve of 0.824 with a sensitivity of 66.2%, a specificity of 87.9% ,a positive and negative likelihood ratios of 5.46 and 0.39, respectively. There was no statistical significant correlation between CF-pDNA levels at study entry with PSA, Gleason score, stage and biochemical recurrence free survival(BRFS). However, with a mean follow up of 13.5 months, we observed significantly shorter BRFS for patients with at least one value above 140 ng/ mL of CF-pDNA during follow up (p= 0.048). Conclusions: CF-pDNA is a potentially valuable biomarker for PCa diagnosis and may have a prognostic role during follow-up of patients with PCa.

    Cardiovascular events associated with androgen deprivation therapy in patients with prostate cancer: A systematic review and meta-analysis.

    Abstract: 40 Background: A recently published meta-analysis of randomized clinical trials (RCT) showed that androgen deprivation therapy (ADT) did not significantly increase cardiovascular mortality in prostate cancer patients. However, cardiovascular morbidity, which can impact quality of life, was not evaluated. Objectives: To evaluate the risk of cardiovascular morbidity and mortality associated with long-term ADT in patients with prostate cancer. Methods: We conducted a literaturesearch from 1960 and June 2012. We selected RCT and large cohort studies that evaluated first-line endocrine therapy, ADT greater than 6 months, and follow up greater than 1 year. Results: Thirteen studies (137,658 patients) were included. Of four cohort studies, 126,898 patients were included and 10,760 patients were part of nine RCTs. Analysis of the RCTs showed no differences in development of acute myocardial infarction (AMI) (OR 1.23; 95% CI: 0.92 – 1.64; I 2 : 0%) or stroke (OR 1.02; 95% CI: 0.71 – 1.46; I 2 : 0%) among patients receiving ADT or not. The analysis of three randomized studies that reported other nonfatal cardiovascular events demonstrated a significant increase in such events in the group receiving ADT (OR 1.55; 95% CI: 1.09 – 2.20; I 2 : 0%). When large cohort studies were included in the analysis, an increased risk of AMI among men who had ADT was found ( OR 2.01, 95% CI:1.90 – 2.13; I 2 : 91.3%). Conclusions: ADT in prostate cancer patients for at least 6 months is not associated with cardiovascular mortality, acute myocardial infarct and stroke. However, patients receiving ADT had a significant increase in nonfatal cardiovascular events.
