63 Background: Active surveillance (AS) is an option for patients with low risk prostate cancer (PCa); however, determining disease progression is challenging. At the NCI, multiparametric MRI (MP-MRI) with our biopsy protocol (MR-US fusion-guided plus 12 core extended sextant biopsy) has been used to confirm eligibility for AS. We evaluated the utility of these modalities in monitoring patients on AS. Methods: Patients who underwent MP-MRI of the prostate with biopsy per our protocol between 2007-2012 were reviewed. We selected a subset who met Johns Hopkins criteria for AS (Gleason score≤6, PSA density≤0.15, tumor involvement of ≤2 cores, and ≤50% of any single core) by outside 12−core TRUS biopsy. Patients with Gleason score≤6 confirmed at first NCI biopsy session were followed with annual MP-MRI and biopsy. MRI progression was defined as an increase in MP-MRI suspicion level, lesion diameter, or number of lesions. Pathologic progression was defined as an increase to Gleason score≥7 in either 12-core or MR-fusion biopsy. We determined the association between MRI and pathologic progression. Results: 129 patients met JHU criteria for AS by outside biopsy. Mean age was 61.6 years and mean PSA 5.16ng/mL. 28/129 (21.7%) patients had Gleason score ≥7 at first NCI biopsy session.31 patients had at least two biopsy sessions (mean follow up 18 months, range 12-54 months) of which 9/31 (29%) increased in Gleason score, all to 3+4=7. Fusion biopsy detected more pathologic progression than did standard biopsy (Table). The positive predictive value of MP-MRI for pathologic progression was 50%, while the negative predictive value was 84%. The sensitivity and specificity of MP-MRI for increase in Gleason score was 67% and 73%, respectively. Conclusions: Stable findings on MP-MRI are associated with Gleason score stability in patients with low-risk PCa choosing AS. The majority of patients who had pathologic progression were detected on fusion biopsy, which may suggest that random biopsies are unnecessary in this population. Larger studies are needed to validate these findings. [Table: see text]

114 Background: The utility of serial magnetic resonance imaging (MRI)/ultrasound (US) fusion targeted prostate biopsy in men with prostate cancer (PCa) on active surveillance (AS) have not been clearly defined. We sought to investigate the rate of Gleason upgrading both on sequential fusion targeted and systematic biopsies among men with low-risk PCa managed with AS. Methods: We retrospectively queried an institutional database of 800 patients undergoing MRI/US fusion biopsy to identify 209 patients on AS with at least two fusion biopsies between December 2013 and November 2016. Men with National Comprehensive Cancer Network (NCCN) very low-risk and low-risk criteria were included. Gleason upgrade was defined as detection of Gleason score >=3+4. The proportion of patients experiencing upgrade on systematic, fusion, or both biopsy techniques was tabulated. Associations of clinical, pathologic, and imaging factors with biopsy upgrade were analyzed by logistic regression. Results: Of 209 patients undergoing MRI/US fusion biopsy, 73 (35.0%) had at least two targeted biopsies (66% very low-risk and 34% low-risk PCa). The time between biopsies was 12.6 months (11.2-17.7). The median PSA and PSA density were 5.4 ng/mL (4.2-7.1) and 0.11 ng/mL/mL (0.07-0.18), respectively. 21 (29%) patients experienced Gleason upgrade on subsequent biopsy. Of those, 6 (8%), 5 (7%), and 10 (14%) had upgrade on systematic biopsy only, fusion biopsy only, and both systematic and fusion biopsy, respectively. Patients with upgrade on subsequent biopsy had higher PSA (p=0.02) and PSA density (p=0.02), and were among low-risk disease population (p=0.03). In logistic regression models, greater number of positive cores in systematic biopsy (OR 1.88; 95% CI 1.23-2.92; p=0.005) was associated with the total Gleason upgrade on repeated biopsy. Conclusions: In men with favorable risk prostate cancer managed with AS, Gleason upgrade was detected in a 29% of patients on a second MRI/US fusion biopsy including both targeted and systematic regions. These findings support the continued use of both MRI fusion and systematic biopsy during surveillance due to risks of reclassification over time.

Background: circulating levels of lymphocytes, platelets and neutrophils have been identified as factors related to unfavorable clinical outcome for many solid tumors. The aim of this cohort study is to evaluate and validate the use of the Prostatic Systemic Inflammatory Markers (PSIM) score in predicting and improving the detection of clinically significant prostate cancer (csPCa) in men undergoing robotic radical prostatectomy for low-risk prostate cancer who met the inclusion criteria for active surveillance. Methods: we reviewed the medical records of 260 patients who fulfilled the inclusion criteria for active surveillance. We performed a head-to-head comparison between the histological findings of specimens after radical prostatectomy (RP) and prostate biopsies. The PSIM score was calculated on the basis of positivity according to cutoffs (neutrophil-to-lymphocyte ratio (NLR) 2.0, platelets-to-lymphocyte ratio (PLR) 118 and monocyte-to-lymphocyte-ratio (MLR) 5.0), with 1 point assigned for each value exceeding the specified threshold and then summed, yielding a final score ranging from 0 to 3. Results: median NLR was 2.07, median PLR was 114.83, median MLR was 3.69. Conclusion: we found a significantly increase in the rate of pathological International Society of Urological Pathology (ISUP) ≥ 2 with the increase of PSIM. At the multivariate logistic regression analysis adjusted for age, prostate specific antigen (PSA), PSA density, prostate volume and PSIM, the latter was found the sole independent prognostic variable influencing probability of adverse pathology.
