Introduction. To assess the performance of five previously described clinicopathological definitions of low-risk prostate cancer (PC).Materials and Methods. Men who underwent radical prostatectomy (RP) for clinical stage ≤T2, PSA <10 ng/mL, Gleason score <8 PC, diagnosed by transperineal template-guided saturation biopsy were included. The performance of five previously described criteria (i.e., criteria 1–5, criterion 1 stringent (Gleason score 6 + ≤5 mm total max core length PC + ≤3 mm max per core length PC) up to criterion 5 less stringent (Gleason score 6-7 with ≤5% Gleason grade 4) was analysed to assess ability of each to predict insignificant disease in RP specimens (defined as Gleason score ≤6 and total tumour volume <2.5 mL, or Gleason score 7 with ≤5% grade 4 and total tumour volume <0.7 mL).Results. 994 men who underwent RP were included. Criterion 4 (Gleason score 6) performed best with area under the curve of receiver operating characteristics 0.792. At decision curve analysis, criterion 4 was deemed clinically the best performing transperineal saturation biopsy-based definition for low-risk PC.Conclusions. Gleason score 6 disease demonstrated a superior trade-off between sensitivity and specificity for clarifying low-risk PC that can guide treatment and be used as reference test in diagnostic studies.

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]

Abstract Background This study aimed to investigate the misclassification rates of Asian-American patients with low-risk prostate cancer who underwent radical prostatectomy (RP). Methods Patients diagnosed with low-risk PCa treated with RP between 2010 and 2015 in the Surveillance, Epidemiology, and End Results (SEER) database were included in this study. Then, basic characteristics and pathological outcomes of enrolled patients were retrospectively extracted. We compared the rates of upgrading and/or upstaging between Asian-American patients and White/Black patients. Moreover, temporal trend analyses were performed to explore the changes in upgrading and upstaging rates in each race over time. Finally, logistic regression models were constructed to explore the role of Asian race in upgrading and upstaging and to screen out potential risk factors for predicting upgrading and upstaging in Asian-American patients. Results In patients with low-risk PCa, Asian-Americans had significantly higher rate of upgrading than Whites (51.25% vs. 45.18%, P<0.001), while no statistical difference was found in the comparison of upstaging rate (10.01 vs. 10.01, P=0.536). Moreover, Asian-Americans were more likely to upgrade to diseases with higher ISUP grade than Whites (P=0.010). The rate of upgrading increased significantly over time in White and Black patients, but not in Asian-American patients. Finally, race seemed to be an independent risk factor for predicting upgrading, while the racial differences seemed to be more pronounced between White and Black patients. Conclusion Asian-American patients had a significantly higher rate of upgrading than White patients. Moreover, Asian-American patients were more likely to upgrade to diseases with higher ISUP grade. Further risk assessment before clinical decision for low-risk PCa patients with the help of significant clinical variables is required.
