AbstractAtypical small acinar proliferation (ASAP) occurs in approximately 5% of prostate biopsies. Approximately 30–40% of patients with ASAP have biopsy detectable prostate cancer (PCa) within 5 years. Current guidelines recommend a repeat biopsy within 3–6 months after the initial diagnosis. The aim of the present study was to examine the association between ASAP and subsequent diagnosis of clinically significant PCa (csPCa). The need for immediate repeat biopsy was also evaluated. We identified 212 patients with an ASAP diagnosis on their first biopsy at our institution between February 2006 and March 2018. Of these patients, 102 (48.1%) had at least one follow-up biopsy. Clinicopathologic features including rates of subsequent PCa and csPCa were assessed. Thirty-five patients subsequently underwent radical prostatectomy (RP). Their pathologic results were reviewed. csPCa was defined as the presence of Gleason score (GS) ≥ 3 + 4 in ≥ 1 biopsy core. Adverse pathology (AP) was defined as high-grade (primary Gleason pattern ≥ 4) or non-organ-confined disease (pT3/N1) after RP. Of 102 patients, 87 (85.3%), 13 (12.7%), and 2 (2.0%) had one, two, and three follow-up biopsies, respectively. Median time from the initial ASAP diagnosis to the 2nd follow-up biopsy and the last follow-up biopsy were 21.9 months (range 1–129 months) and 27.7 months (range 1–129 months), respectively. Of these patients, 46 (45.1%) were subsequently diagnosed with PCa, including 20 (19.6%) with csPCa. Only 2 (2.0%) patients had GS ≥ 8 disease. Five (4.9%) patients had number of positive cores > 3. Of 35 patients who subsequently underwent RP, seven (20%) had AP after RP and 17 (48.6%) showed GS upgrading. Of these 17 patients, the vast majority (16/17, 94.1%) had GS upgrading from 3 + 3 to 3 + 4. 45.1% of patients with an initial diagnosis of ASAP who had repeat prostate biopsy were subsequently diagnosed with PCa and 19.6% were found to have csPCa. Our findings add further evidence that after a diagnosis of ASAP, a repeat biopsy is warranted and that the repeat biopsy should not be postponed.

Background: Atypical small acinar proliferation (ASAP) occurs in approximately 5% of prostate biopsies. Approximately 30%–40% of these patients may develop prostate cancer (PCa) within a 5-year period, often not clinically significant. Current guidelines recommend a repeat biopsy within 3–6 months after the initial diagnosis, but it seem not to be the best strategy. Methods: Objectives—evaluating the natural history of ASAP, stratifying the risk of csPCa after ASAP, identifying predictive factors of PCa after atypical diagnosis. Materials and methods—retrospective single-institutional study on patients undergoing prostate biopsy for suspicious PCa (2005–2016). We evaluated the incidence of overall PCa, intermediate-high risk of PCa and csPCa in case of ASAP, according to D’Amico classification and Epstein modified criteria. Results: Out of 4.567 patients undergoing prostate biopsy, ASAP was detected in 2.6% of cases. All patients with ASAP underwent repeat saturation biopsy within 6 months and PCa was diagnosed in 34.5%. According to D’Amico classification, 26%, 5.9%, and 2.5% had low, intermediate, and high-risk disease, respectively. According modified Epstein criteria, the incidence of csPCa was 12.6%. LRT showed that the overall probability to develop PCa doubled when PSA density (PSAD) moved from values lower than 0.13 ng/ml/cc to class 0.13–0.30 ng/ml/cc, and it tripled when PSAD was higher than 0.30 ng/ml/cc. Conclusions: The rate of csPCa in patients with an initial diagnosis of ASAP who had repeat biopsy was 12.6%. The overall PCa rate was 34.5%. Among patient undergoing RP, an upgrading from ncsPCa to csPCa was reported in 35% of cases. PSAD is the only predictive factor directly associated to the risk of developing PCa on repeat biopsy. These findings suggest that immediate repeat biopsy remains the correct strategy in absence of novel predictor factors and non-invasive diagnostic evaluations.

Abstract Background:Venous thromboembolism (VTE) is a highly prevalent complication of cancer and its treatment and is commonly treated with anticoagulation1. However, there are limited data regarding the use of therapeutic anticoagulation in patients with brain metastases, due to concerns for intracranial hemorrhage (ICH). Methods:We retrospectively identified cancer patients who were diagnosed with brain metastasis between 12/2005 and 7/2017, and subsequently underwent whole brain radiation at the Cleveland Clinic. Patients with primary brain tumors, leptomeningeal disease alone, and absence of follow-up brain imaging were excluded. Clinically significant ICH was defined as ICH resulting in focal neurologic deficit or required neurosurgery, as previously described2. Cumulative incidence of ICH from initial diagnosis of brain metastasis was calculated with death as competing risk. Difference between cumulative incidence estimates was tested using Gray's test. Overall survival (OS) calculated from initial diagnosis of brain metastasis, estimated by the Kaplan-Meier method, and compared by the log-rank test. Median follow-up time was calculated using reverse Kaplan-Meier method. Predictors identified as statistically significant on univariate logistic regression analysis (p<0.05) were selected for multivariate analysis. Results:We screened568 patients and identified 407 who meet inclusion criteria. Seventy-eight (19%) patients received therapeutic anticoagulation (AC) [enoxaparin: n = 46 (59%), warfarin: n = 27 (35%), apixaban/rivaroxaban: n = 3 (4%), unfractionated heparin: n = 2 (2%)] due to VTE after diagnosis of brain metastasis, whereas 329 (81%) patients did not receive any therapeutic dose of AC. There were more female patients in the AC cohort, but other baseline characteristics were similar in both cohorts (Table 1). In the AC cohort, 11 of 78 (14%) patients had ICH, of which 6 (55%) were clinically insignificant and 5 (45%) were clinically significant at initial diagnosis of brain metastasis. Five of 11 patients were already on AC before diagnosis of brain metastasis. In the no-AC cohort, 65 of 329 (20%) patients had ICH, of which 53 (82%) clinically insignificant and 12 (18%) clinically significant at initial diagnosis of brain metastasis. Median follow-up of patients was 28 months. The 3-year cumulative incidence of clinically insignificant ICH in AC and no-AC groups was 7.7 (95% CI: 1.8 - 13.6) and 21.3 (95% CI: 16.5 - 26.1), respectively (p = 0.017). The 3-year cumulative incidence of clinically significant ICH in AC and no-AC groups was 12.0 (95% CI: 4.6 - 19.4) and 4.9 (95% CI: 2.6 - 7.4), respectively (p = 0.044). The 3-year cumulative incidence of all ICH in AC and no-AC groups was 19.7 (95% CI: 10.7 - 28.7) and 25.8 (95% CI: 20.9 - 30.7), respectively (p = 0.27). The 3-year OS in AC and no-AC groups was 13.6 (95% CI: 6.9 - 26.4) and 17.6 (95% CI: 12.9 - 23.9), respectively (p = 0.64) (Figure 1). In univariable analysis, AC vs no-AC [OR: 2.39, 95% CI: 1.00 - 5.48, p = 0.044] and primary cancer (melanoma vs lung) [OR: 5.62, 95% CI: 1.78 - 16.49, p = 0.002] were predictors of clinically significant ICH after diagnosis of brain metastasis (Table 2). In multivariable analysis, only primary cancer (melanoma vs lung) [OR: 6.19, 95% CI: 1.92 - 18.88, p = 0.001]remained a statistically significant predictor of clinically significant ICH after diagnosis of brain metastasis. Conclusion: In this relatively large cohort of patients with brain metastasis, use of therapeutic anticoagulation did not influence the incidence of developing ICH but was associated with a greater risk of clinically significant ICH. This increase was, however, not linked to differences in overall survival. Nearly all patients in our AC cohort were treated with enoxaparin; ongoing studies will examine whether anticoagulation with DOACs is associated with similar outcomes.

Objectives: To establish whether repeated trans-rectal ultrasound-guided Prostate Needle Biopsies (PNBx) performed in men with diagnosis of Small Acinar Atypical Proliferation (ASAP) predispose these subjects to Erectile Dysfunction (ED) and to evaluate if EcoColorDoppler (ECD) can help to reduce this side effect. Materials and methods: We performed a retrospective study regarding 190 men with diagnosis of ASAP detected between January 2001 and December 2011, who underwent to repeated prostate needle biopsies (PNBx). These patients were investigated about Erectile Function (EF) and Lower Urinary tract Symptoms (LUTS) using International Index of Erectile Function (IIEF-5) and International Prostate Symptom Score (IPSS) questionnaires before the first PNBx and 3 months after each other one. In particular, among the 89 men without ED before first PNBx, we compared IIEF-5 score between 64 patients who underwent to standard PNBx and 25 patients submitted to a PNBx done with in addition ECD ultrasound imaging. Results: Mean patient age was 65 years (SD 7.7); mean follow-up was 3.2 years (SD 1.8) and the mean number of re-biopsies completed was 2 (SD 1.5). Among the 143 men considered, only 89 resulted with a normal EF (IIEF-5 score &gt; 21): in this group incidence of ED (IIEF-5 score &lt; 21) among patients who underwent to standard PNBx was 4/64 (6.25%) while in patients submitted to a PNBx with ECD was 1/25 (4%). A greater decrease of EF was observed in patients undergone to 3 or more biopsies; no relationship between IPSS score and re-PNBx was identified. Conclusion: Repeated PNBx done in patients with diagnosis of ASAP appear to get worse EF; number of biopsies seems to increase the risk of ED. Use of ECD in transrectal ultrasound- guided PNBx may have a role to avoid neurovascular bundles (NVBs) and preserve EF; anyway further studies are highly recommended to validate this hypothesis.

Purpose. Atypical small acinar proliferation (ASAP) is diagnosed in 1-2% of prostate biopsies. 30–40% of patients with ASAP may be diagnosed with prostate cancer (PCa) on repeat biopsy. Our objective was to examine the association between ASAP and subsequent diagnosis of intermediate/high risk PCa.Materials and Methods. Ninety-six patients who underwent prostate biopsy from 2000 to 2013 and were diagnosed with ASAP were identified. Clinicopathologic features were analyzed. Comparison was made between those with subsequent PCa on repeat biopsy and those with benign repeat pathology.Results. 56/96 (58%) patients had a repeat biopsy. 22/56 (39%) were subsequently diagnosed with PCa. There was no significant difference in patients’ characteristics. Presence of HGPIN on initial biopsy was associated with a benign repeat biopsy (68% versus 23%). 17/22 (77%) had Gleason grade (GG) 3+3 disease and only 5/22 (23%) had GG 3+4 disease.Conclusions. 22/56 patients (39%) of patients who underwent a subsequent prostate biopsy following a diagnosis of ASAP were found to have PCa. 77% of these men were diagnosed with GG 3+3 PCa. Only 23% were found to have intermediate risk PCa and no high risk PCa was identified. Immediate repeat prostate biopsy in patients diagnosed with ASAP may be safely delayed. A multi-institutional cohort is being analyzed.

Introduction: This study evaluates the clinical benefit of magnetic resonance-transrectal ultrasound (MR-TRUS) fusion biopsy over systematic biopsy between first-time and repeat prostate biopsypatients with prior atypical small acinar proliferation (ASAP).Methods: 100 patients were enrolled in a single-centre prospective cohort study: 50 for first biopsy, 50 for repeat biopsy with prior ASAP. Multiparameteric magnetic resonance imaging (MP-MRI) and standard 12-core ultrasound biopsy (Std-Bx) were performed on all patients. Targeted biopsy using MRI-TRUS fusion (Fn-Bx) was performed f suspicious lesions were identified on the prebiopsyMP-MRI. Classification of clinically significant disease was assessed independently for the Std-Bx vs. Fn-Bx cores to compare the two approaches.Results: Adenocarcinoma was detected in 49/100 patients (26 first biopsy, 23 ASAP biopsy), with 25 having significant disease (17 first, 8 ASAP). Fn-Bx demonstrated significantly higher per-core cancer detection rates, cancer involvement, and Gleason scores for first-time and ASAP patients. However, Fn-Bx was significantly more likely to detect significant cancer missed on Std-Bx for ASAP patients than first-time biopsy patients. The addition of Fn-Bx to Std-Bx for ASAP patients had a 166.7% relative risk reduction for missing Gleason ≥ 3 + 4 disease (number needed to image with MP-MRI=10 patients) compared to 6.3% for first biopsy (number to image=50 patients). Negative predictive value of MP-MRI for negative biopsy was 79% for first-time and 100% for ASAP patients, with median followup of 32.1 ± 15.5 months.Conclusions: MR-TRUS Fn-Bx has a greater clinical impact for repeat biopsy patients with prior ASAP than biopsy-naïve patients by detecting more significant cancers that are missed on Std-Bx.

32 Background: Current pre-radical prostatectomy (RP) nomograms predicting lymph node involvement (LNI) are based on systematic 12-core prostate biopsies (PBx). With the introduction of mpMRI, cognitive or fusion biopsies have become prevalent, often in the absence of systematic cores. We examine the practical application of MR biopsy data using established pre-RP nomograms and the potential implications on RP intra-operative decision making. Methods: Utilizing a prospectively maintained single institution database, all patients who underwent MRI-based PBx prior to RP were identified. Each patient was assessed using the MSKCC Kattan nomogram and the Briganti nomogram using the following iterations: 1) Targeted [T] (targeted cores alone), 2) Targeted & Systematic [TS] and 3) Targeted Augmented [TA]. The TA iteration utilized targeted core data alone and assumed negative remaining systematic cores for a total 12 core. Nomogram outcomes, specifically risk of LNI, was compared across iterations. Clinically significant impact was defined as a change in risk above or below 2% (Δ2) or 5% (Δ5), based on current guidelines recommendations for lymph node dissection. Results: 69 men met inclusion criteria (6 targeted, 63 systematic + targeted PBx). In the 6 men with targeted only biopsies, using the Kattan and Briganti nomograms, Δ2 occurred in 1 patient (16.7%) and Δ5 in 1-2 patients (16.7-33.3%); in all, TA iteration LNI was lower than the T iteration. In the 58 patients with positive targeted biopsy cores, Δ2 and Δ5 were 8.62-32.76% and 25.86-37.93%, respectively. In the subset of 52 patients with both targeted and systematic biopsies, using their TS nomogram as an internal validation, the TA iteration was a better approximation of their TS outcomes than their T iteration in 48% (Kattan) and 67% (Briganti) of patients. Conclusions: mpMRI-based PBx results, and in particular those from targeted biopsy cores alone, yield significantly different results using established pre-RP nomograms. Therefore, future nomograms must better incorporate MRI biopsy data and provide guidelines on how to account for targeted cores. In the interim, augmenting targeted biopsy data may bridge the gap.
