Abstract
OBJECTIVE To compare clinically significant prostate cancer detection with TP-TBx utilizing software vs cognitive fusion. It is established that MRI prior to prostate biopsy improves detection of clinically significant cancer (csPCa, Grade Group ≥2). MRI/US fusion targeted biopsy via a transperineal approach (TP-TBx) is increasing in utilization due to the clean percutaneous approach that greatly reduces postbiopsy infection. However, the comparative effectiveness of formal software fusion over cognitive fusion remains under studied. MATERIALS AND METHODS We performed a retrospective multicenter study from June 2020 to July 2022 including age, race, prostate-specific antigen (PSA), prostate volume, PI-RADS, lesion size(s), number of cores sampled, indication (elevated PSA, prior negative, active surveillance) and anesthesia type. Surgeon preference determined use of cognitive (PrecisionPoint) vs software fusion techniques. Multivariable logistic regression determined factors associated with TP-TBx detection of csPCa. RESULTS We identified 490 patients (201 cognitive, 289 software fusion) who underwent TP-TBx. Patient age, PSA, number of targets, and PI-RADS were similar (all P > .05). Software fusion TP-TBx had 4 [95% confidence interval (CI) 3-5] more (estimated median difference) systematic cores sampled. csPCa was detected in 44% of all patients. In adjusted analysis, cognitive vs software fusion was similar in detection of csPCa (odds ratio 1.46, 95% CI 0.82-2.58). CONCLUSION Cognitive vs software fusion TP-TBx has similar csPCa detection, despite fewer systematic cores taken with cognitive fusion. The expense, additional time requirement, and similar outcomes of software fusion platforms confers higher value to cognitive TP-Bx.

Abstract
PURPOSE We sought to examine the association of extraprostatic extension (EPE) with biochemical recurrence (BCR) separately in men with Grade Group (GG) 1 and GG2 prostate cancer (PCa) treated with radical prostatectomy. MATERIALS AND METHODS We reviewed our institutional database of patients who underwent radical prostatectomy for PCa between 2005 and 2022 and identified patients with GG1 and GG2 disease on final pathology. Fine-Gray competing risk models with an interaction between EPE (yes vs no) and GG (GG1 vs GG2) were used to examine the relationship between disease group and BCR-free survival. RESULTS The cohort consisted of 6309 men, of whom 169/2740 (6.2%) with GG1 disease had EPE while 1013/3569 (28.4%) with GG2 disease had EPE. Median follow-up was 4 years. BCR occurred in 400/6309 (6.3%) patients. For men with GG1, there was no statistically significant difference in BCR-free survival for men with vs without EPE (subdistribution HR = 0.88; 95% CI: 0.37-2.09). However, for GG2 patients BCR-free survival was significantly worse for those with vs without EPE (subdistribution HR = 1.97, 95% CI: 1.54-2.52). CONCLUSIONS Although there is a subset of GG1 PCas capable of invading through the prostatic capsule, patients with GG1 PCa and EPE at prostatectomy experience similar biochemical recurrence and survival outcomes compared to GG1 patients without EPE. However, among men with GG2, EPE connotes a worse prognosis.

Abstract
Novel perioperative strategies are needed to reduce recurrence rates in patients undergoing nephrectomy for high-risk, non-metastatic clear cell renal cell carcinoma (ccRCC). We conducted a prospective, phase I trial of neoadjuvant nivolumab prior to nephrectomy in 15 evaluable patients with non-metastatic ccRCC. We leveraged tissue from that cohort to elucidate the effects of PD-1 inhibition on immune cell populations in ccRCC and correlate the evolving immune milieu with anti-PD-1 response. We found that nivolumab durably induces a pro-inflammatory state within the primary tumor, and baseline immune infiltration within the primary tumor correlates with nivolumab responsiveness. Nivolumab increases CTLA-4 expression in the primary tumor, and subsequent nephrectomy increases circulating concentrations of sPD-L1, sPD-L3 (sB7-H3), and s4-1BB. These findings form the basis to consider neoadjuvant immune checkpoint inhibition (ICI) for high-risk ccRCC while the tumor remains in situ and provide the rationale for perioperative strategies of novel ICI combinations.

Abstract
BACKGROUND AND OBJECTIVE The transrectal biopsy approach is traditionally used to detect prostate cancer. An alternative transperineal approach is historically performed under general anesthesia, but recent advances enable transperineal biopsy to be performed under local anesthesia. We sought to compare infectious complications of transperineal biopsy without antibiotic prophylaxis versus transrectal biopsy with targeted prophylaxis. METHODS We assigned biopsy-naïve participants to undergo transperineal biopsy without antibiotic prophylaxis versus transrectal biopsy with targeted prophylaxis (rectal culture screening for fluoroquinolone-resistant bacteria and antibiotic targeting to culture and sensitivity results) through a multicenter, randomized trial. The primary outcome was post-biopsy infection captured by a prospective medical review and patient report on a 7-d survey. The secondary outcomes included cancer detection, noninfectious complications, and a numerical rating scale (0-10) for biopsy-related pain and discomfort during and 7-d after biopsy. KEY FINDINGS AND LIMITATIONS A total of 658 participants were randomized, with zero transperineal versus four (1.4%) transrectal biopsy infections (difference -1.4%; 95% confidence interval [CI] -3.2%, 0.3%; p = 0.059). The rates of other complications were very low and similar. Importantly, detection of clinically significant cancer was similar (53% transperineal vs 50% transrectal, adjusted difference 2.0%; 95% CI -6.0, 10). Participants in the transperineal arm experienced worse periprocedural pain (0.6 adjusted difference [0-10 scale], 95% CI 0.2, 0.9), but the effect was small and resolved by 7-d. CONCLUSIONS AND CLINICAL IMPLICATIONS Office-based transperineal biopsy is tolerable, does not compromise cancer detection, and did not result in infectious complications. Transrectal biopsy with targeted prophylaxis achieved similar infection rates, but requires rectal cultures and careful attention to antibiotic selection and administration. Consideration of these factors and antibiotic stewardship should guide clinical decision-making. PATIENT SUMMARY In this multicenter randomized trial, we compare prostate biopsy infectious complications for the transperineal versus transrectal approach. The absence of infectious complications with transperineal biopsy without the use of preventative antibiotics is noteworthy, but not significantly different from transrectal biopsy with targeted antibiotic prophylaxis.

Abstract
This study aimed to assess the accuracy of intraprostatic tumor volume measurements on prostate-specific membrane antigen-targeted 18F-DCFPyL PET/CT made with various segmentation methods. An accurate understanding of tumor volumes versus segmentation techniques is critical for therapy planning, such as radiation dose volume determination and response assessment. Methods: Twenty-five men with clinically localized, high-risk prostate cancer were imaged with 18F-DCFPyL PET/CT before radical prostatectomy. The tumor volumes and tumor-to-prostate ratios (TPRs) of dominant intraprostatic foci of uptake were determined using semiautomatic segmentation (applying SUVmax percentage [SUV%] thresholds of SUV30%-SUV70%), adaptive segmentation (using adaptive segmentation percentage [A%] thresholds of A30%-A70%), and manual contouring. The histopathologic tumor volume (TV-Histo) served as the reference standard. The significance of differences between TV-Histo and PET-based tumor volume were assessed using the paired-sample Wilcoxon signed-rank test. The Spearman correlation coefficient was used to establish the strength of the association between TV-Histo and PET-derived tumor volume. Results: Median TV-Histo was 2.03 cm3 (interquartile ratio [IQR], 1.16-3.36 cm3), and median TPR was 10.16%. The adaptive method with an A40% threshold most closely determined the tumor volume, with a median difference of +0.19 (IQR, -0.71 to +2.01) and a median relative difference of +7.6%. The paired-sample Wilcoxon test showed no significant difference in PET-derived tumor volume and TV-Histo using A40%, A50%, SUV40%, and SUV50% threshold segmentation algorithms (P > 0.05). For both threshold-based segmentation methods, use of higher thresholds (e.g., SUV60% or SUV70% and A50%-A70%) resulted in underestimation of tumor volumes, and use of lower thresholds (e.g., SUV30% or SUV40% and A30%) resulted in overestimation of tumor volumes relative to TV-Histo and TPR. Manual segmentation overestimated the tumor volume, with a median difference of +2.49 (IQR, 0.42-4.11) and a median relative difference of +130%. Conclusion: Segmentation of intraprostatic tumor volume and TPR with an adaptive segmentation approach most closely approximates TV-Histo. This information might be used to guide the primary treatment of men with clinically localized, high-risk prostate cancer.

Abstract
Background As the adoption of active surveillance (AS) for small renal masses (SRMs) grows, the number of elderly patients enrolled for a prolonged period of time will increase. However, our understanding of comparative growth rates (GRs) in aging patients with SRMs remains poor. Objective To examine whether particular age cutoffs are associated with an increased GR for patients undergoing AS for SRMs. Design setting and participants We identified all patients with SRMs enrolled in the multi-institutional, prospective Delayed Intervention and Surveillance for Small Renal Masses (DISSRM) registry since 2009 who elected for AS. Outcome measurements and statistical analysis Two definitions of GR were examined: GR from the initial image (GRi) and GR from the prior image (GRp). Image measurements were dichotomized based on patient age at the time of imaging. Multiple age cutoffs were examined: 65, 70, 75, and 80 yr. Mixed-effect linear regression examined the associations between age and GR, with controlling to account for multiple measurements from the same individual. Results and limitations We examined 2542 measurements from 571 patients. The median age at enrollment was 70.9 yr (interquartile range [IQR] 63.2-77.4) with a median tumor diameter of 1.8 cm (IQR 1.4-2.5). As a continuous variable, age was not associated with GRi (-0.0001 cm/yr, 95% confidence interval [CI] -0.007 to 0.007, p = 0.97) or GRp (0.008 cm/yr, 95% CI -0.004 to 0.020, p = 0.17) after adjustment. The only age thresholds associated with an increased GR were 65 yr for GRi and 70 yr for GRp. Limitations include the one-dimensional nature of the measurements used. Conclusions Increased age for patients on AS for SRMs is not associated with increased GRs. Patient summary We examined whether patients undergoing active surveillance (AS) exhibited accelerated growth of their small renal masses (SRMs) after a certain age. No demonstrable change was seen, suggesting that AS is a safe and durable management option for aging patients with SRMs.

Abstract
B7 homolog 3 (B7-H3; CD276), a tumor-associated antigen and possible immune checkpoint, is highly expressed in prostate cancer (PCa) and is associated with early recurrence and metastasis. Enoblituzumab is a humanized, Fc-engineered, B7-H3-targeting antibody that mediates antibody-dependent cellular cytotoxicity. In this phase 2, biomarker-rich neoadjuvant trial, 32 biological males with operable intermediate to high-risk localized PCa were enrolled to evaluate the safety, anti-tumor activity and immunogenicity of enoblituzumab when given before prostatectomy. The coprimary outcomes were safety and undetectable prostate-specific antigen (PSA) level (PSA0) 1 year postprostatectomy, and the aim was to obtain an estimate of PSA0 with reasonable precision. The primary safety endpoint was met with no notable unexpected surgical or medical complications, or surgical delay. Overall, 12% of patients experienced grade 3 adverse events and no grade 4 events occurred. The coprimary endpoint of the PSA0 rate 1 year postprostatectomy was 66% (95% confidence interval 47-81%). The use of B7-H3-targeted immunotherapy in PCa is feasible and generally safe and preliminary data suggest potential clinical activity. The present study validates B7-H3 as a rational target for therapy development in PCa with larger studies planned. The ClinicalTrials.gov identifier is NCT02923180.

Abstract
708 Background: Novel perioperative strategies are needed to reduce recurrence rates in patients undergoing nephrectomy for high-risk, non-metastatic clear cell renal cell carcinoma (ccRCC). We sought to (1) elucidate the effects of PD-1 inhibition on primary tumor-infiltrating and circulating immune cell populations in ccRCC and (2) correlate tumor microenvironment and circulating immune cell compositions with response to anti-PD-1 therapy. Methods: We conducted a prospective, phase I trial of neoadjuvant nivolumab prior to nephrectomy in 15 evaluable patients with non-metastatic ccRCC. We leveraged tissue from this cohort to elucidate the effects of PD-1 inhibition on immune cell populations in ccRCC and correlate the evolving immune milieu with anti-PD-1 response using fluorescence-activated cell sorting, bulk RNA sequencing with protein activity inference, and enzyme-linked immunosorbent assay for circulating cytokines. Results: We found that nivolumab durably promotes a pro-inflammatory state within the primary tumor, as evidenced by a sustained increase in the effector T cell phenotype and decreased representation of regulatory T cell subsets. Baseline immune infiltration within the primary tumor including T effector and myeloid enrichment along with angiogenic depletion correlates with nivolumab responsiveness. Nivolumab increases CTLA-4 expression in the primary tumor, and subsequent nephrectomy increases circulating concentrations of sPD-L1, sPD-L3 (sB7-H3), and s4-1BB. Conclusions: Our findings form the basis to consider neoadjuvant immune checkpoint inhibition (ICI) for high-risk ccRCC while the tumor remains in situ and provide the rationale for perioperative strategies of novel ICI combinations.

Abstract
5015 Background: B7-H3/CD276, a member of the B7 superfamily, is highly expressed in prostate cancer (PCa) and is associated with rapid biochemical recurrence and early metastases. B7-H3 is the only checkpoint candidate to have a presumptive androgen receptor binding site, suggesting interaction with the androgen axis. Enoblituzumab (MacroGenics) is an investigational humanized Fc-optimized B7-H3–targeting antibody that induces antibody dependent cellular cytotoxicity (ADCC). Methods: In this phase 2 single-arm biomarker-rich neoadjuvant trial, men with operable intermediate- and high-risk localized prostate cancer (Grade Groups 3-5) were enrolled to evaluate the safety, anti-tumor efficacy, and immunogenicity of enoblituzumab when given prior to prostatectomy. Patients received enoblituzumab (15 mg/kg IV weekly x 6) prior to surgery. Prostate glands were harvested 2 weeks after the last dose, and were examined for pathologic and immunologic endpoints. The co-primary outcomes were safety and PSA0 at 1 year post-op. Pre-planned secondary outcomes were PSA and Gleason grade group change from biopsy to prostatectomy. Results: 32 men were enrolled. Grade 3/4 adverse events occurred in 12% of patients. One patient developed a grade-3 infusion reaction, and one had immune myocarditis that improved with steroids. Pre-prostatectomy PSA declines of >10% were observed in 31% of patients (95% CI: 16-50%). PSA0 at 1 year post-op was seen in 66% of men (95% CI: 47-81%). Median time to PSA recurrence was not reached, with a median follow-up of 30 months. Gleason group upgrade, no change, and downgrade was observed in 13%, 37%, and 50% of patients. Gleason grade group changes were significantly associated with enoblituzumab treatment compared to 1:1 matched historical controls (p=0.023). Tumor microenvironment profiling by NanoString GeoMx spatial proteomics and PanCancer IO 360 mRNA expression analysis revealed post-treatment upregulation of CD8+ T cells, PD-1/PD-L1 expression, and immune activation (granzyme B, IFN signaling, myeloid inflammation). There was a significant association between CD8+ T-cell increases and Gleason grade group declines. First-in-human antigen spread profiling revealed no safety concerns. TCR sequencing showed focused peripheral expansion of tumor associated T-cell clones that correlated with PSA0 at 1 year. Whole exome and RNAseq data, and clinical correlations, will be presented. Conclusions: In this neoadjuvant trial, inhibition of B7-H3 with enoblituzumab demonstrated favorable safety and encouraging activity in localized PCa patients. Data suggest robust intratumoral induction (adaptive upregulation) of immune checkpoints, T-cell activation, and myeloid inflammation. Enoblituzumab-induced peripheral expansion of tumor associated T-cell clones may be associated with tumor control. Clinical trial information: NCT02923180.

Abstract
Multimodal therapies were combined to eradicate the primary site, metastatic, and micrometastatic disease in men with newly diagnosed, synchronous, oligometastatic prostate cancer. The investigation included companion, phase II studies: total eradication therapy-1 (TET-1) for those treatment-naïve and total eradication therapy-2 (TET-2) for those post-prostatectomy. The treatment-naive protocol included androgen deprivation and docetaxel (with concurrent abiraterone added in a protocol amendment), followed by a prostatectomy, adjuvant radiation (if positive margins, T3/4, or detectable PSA), and metastasis-directed therapy. The post-prostatectomy protocol assigned the same therapies (omitting the prostatectomy). The primary endpoint was an undetectable PSA with recovered testosterone. The safety boundaries were ≤ 50% for grade 3/4 neutropenic and ≤ 20% for grade 3/4 surgical- and radiation-related toxicities. Enrollment was planned for 60 patients per protocol, to detect a PSA progression-free survival ≥ 32%, as compared to 15% in a historic control. Enrollment closed early. An interim analysis was conducted once > 50% of patients were evaluable for the primary endpoint. The primary endpoint duration was assessed by median progression-free survival. 52 patients were enrolled (n = 26 per protocol). Medium follow-up was 30.3 months. 80% (24/30) of evaluable patients achieved the primary endpoint; the duration was not reached. Of those not evaluable, 77% (17/22) had not reached the endpoint and 23% (5/22) had exited. There were 8% (4/52) grade 3/4 neutropenic and 2% (1/48) grade 3/4 surgical or radiation-induced toxicities. Interim findings suggest the trials' endpoints were met, advancing the concept of total eradication therapy in men with oligometastatic prostate cancer.

Abstract
Neoadjuvant immune checkpoint blockade represents a novel approach for potentially decreasing the risk of recurrence in patients with nonmetastatic renal cell carcinoma (RCC). In this early phase clincal tiral, we evaluated the safety and tolerability of neoadjuvant treatment with the programmed cell death protein 1 (PD-1) inhibitor nivolumab in patients with nonmetastatic high-risk RCC. Nonprimary endpoints included objective radiographic tumor response rate, immune-related pathologic response rate, quality of life alterations, and metastasis-free and overall survival. In total, 17 patients were enrolled in this study and underwent surgery without a delay after receiving three every-2-wk doses of neoadjuvant nivolumab. Adverse events (AEs) of any grade occurred in 14 (82.4%) patients, with two (11.8%) experiencing grade 3 events. Ten (58.8%) patients experienced an AE of any grade potentially attributable to nivolumab (all grade 1-2), and no grade 4-5 AEs occurred regardless of treatment attribution. The most common AEs were grade 1 fatigue (41.2%), grade 1 pruritis (29.4%), and grade 1 rash (29.4%). All evaluable patients had stable disease as per established radiographic criteria, with one (6.7%) demonstrating features of an immune-related pathologic response. Quality of life remained stable during treatment, with improvements relative to baseline noted at ≥6 mo postoperatively. Metastasis-free survival and overall survival were 85.1% and 100% at 2 yr, respectively. PATIENT SUMMARY: In this study, we evaluated the safety and tolerability of preoperative administration of three doses of the immune checkpoint inhibitor nivolumab in patients with clinically localized high-risk renal cell carcinoma. We demonstrated the safety of this approach and found that, although most patients will not experience a radiographic response to treatment, a subset may have features of an immune-related pathologic response.

Abstract
BACKGROUND Personalized treatment for clinical T1 renal cortical masses (RCMs) should take into account competing risks related to tumor and patient characteristics. OBJECTIVE To develop treatment-specific prediction models for cancer-specific mortality (CSM), other-cause mortality (OCM), and 90-d Clavien grade ≥3 complications across radical nephrectomy (RN), partial nephrectomy (PN), thermal ablation (TA), and active surveillance (AS). DESIGN, SETTING, AND PARTICIPANTS Pretreatment clinical and radiological features were collected for consecutive adult patients treated with initial RN, PN, TA, or AS for RCMs at four high-volume referral centers (2000-2019). OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Prediction models used competing-risks regression for CSM and OCM and logistic regression for 90-d Clavien grade ≥3 complications. Performance was assessed using bootstrap validation. RESULTS AND LIMITATIONS The cohort comprised 5300 patients treated with RN (n = 1277), PN (n = 2967), TA (n = 476), or AS (n = 580). Over median follow-up of 5.2 yr (interquartile range 2.5-8.7), there were 117 CSM, 607 OCM, and 198 complication events. The C index for the predictive models was 0.80 for CSM, 0.77 for OCM, and 0.64 for complications. Predictions from the fitted models are provided in an online calculator (https://small-renal-mass-risk-calculator.fredhutch.org). To illustrate, a hypothetical 74-yr-old male with a 4.5-cm RCM, body mass index of 32 kg/m2, estimated glomerular filtration rate of 50 ml/min, Eastern Cooperative Oncology Group performance status of 3, and Charlson comorbidity index of 3 has predicted 5-yr CSM of 2.9-5.6% across treatments, but 5-yr OCM of 29% and risk of 90-d Clavien grade 3-5 complications of 1.9% for RN, 5.8% for PN, and 3.6% for TA. Limitations include selection bias, heterogeneity in practice across treatment sites and the study time period, and lack of control for surgeon/hospital volume. CONCLUSIONS We present a risk calculator incorporating pretreatment features to estimate treatment-specific competing risks of mortality and complications for use during shared decision-making and personalized treatment selection for RCMs. PATIENT SUMMARY We present a risk calculator that generates personalized estimates of the risks of death from cancer or other causes and of complications for surgical, ablation, and surveillance treatment options for patients with stage 1 kidney tumors.

Abstract
OBJECTIVE Judicious opioid stewardship would match each patient's prescription to their true medical necessity. However, most prescribing paradigms apply preset quantities and clinical judgment without objective data to predict individual use. We evaluated individual patient and in-hospital parameters as predictors of post-discharge opioid utilization after radical prostatectomy (RP) to provide evidence-based guidance for individualized prescribing. METHODS A prospective cohort of patients who underwent open or robotic RP were followed in the Opioid Reduction Intervention for Open, Laparoscopic, and Endoscopic Surgery (ORIOLES) initiative. Baseline demographics, in-hospital parameters, and inpatient and post-discharge pain medication utilization were tabulated. Opioid medications were converted to oral morphine equivalents (OMEQ). Predictive factors for post-discharge opioid utilization were analyzed by univariable and multivariable linear regression, adjusting for opioid reduction interventions performed in ORIOLES. RESULTS Of 443 patients, 102 underwent open and 341 underwent robotic RP. The factors most strongly associated with post-discharge opioid utilization included inpatient opioid utilization in the final 12 hours before discharge (+39.6 post-discharge OMEQ if inpatient OMEQ was >15 vs. 0), maximum patient-reported pain score (range 0-10) in the 12 hours before discharge (+27.6 OMEQ for pain score ≥6 vs. ≤1), preoperative opioid use (+76.2 OMEQ), and body mass index (BMI; +1.4 OMEQ per 1 kg/m2). A final predictive calculator to guide post-discharge opioid prescribing was constructed. CONCLUSIONS Following RP, inpatient opioid use, patient-reported pain scores, prior opioid use, and BMI are correlated with post-discharge opioid utilization. These data can help guide individualized opioid prescribing to reduce risks of both overprescribing and underprescribing.

Abstract
BACKGROUND This study evaluated the utility of self-reported quality of life (QOL) metrics in predicting mortality among all-comers with renal cell carcinoma (RCC) and externally tested the findings in a registry of patients with small renal masses. METHODS The Surveillance, Epidemiology, and End Results-Medicare Health Outcomes Survey (SEER-MHOS) captured QOL metrics composed of mental component summary (MCS) and physical component summary (PCS) scores. Regression models assessed associations of MCS and PCS with all-cause, RCC-specific, and non-RCC-specific mortality. Harrell's concordance statistic (the C-index) and the Akaike information criterion (AIC) determined predictive accuracy and parsimony, respectively. Findings were tested in the prospective Delayed Intervention and Surveillance for Small Renal Masses (DISSRM) registry. RESULTS In SEER-MHOS, 1494 patients had a median age of 73.4 years and a median follow-up time of 5.6 years. Each additional MCS and PCS point reduced the hazard of all-cause mortality by 1.3% (95% CI, 0.981-0.993; P < .001) and 2.3% (95% CI, 0.971-0.984; P < .001), respectively. Models with QOL metrics demonstrated higher predictive accuracy (C-index, 72.3% vs 70.1%) and parsimony (AIC, 9376.5 vs 9454.5) than models without QOL metrics. QOL metrics exerted a greater effect on non-RCC-specific mortality than RCC-specific mortality. External testing in the DISSRM registry confirmed these findings with similar results for all-cause mortality. CONCLUSIONS Models with self-reported QOL metrics predicted all-cause mortality in patients with RCC with higher accuracy and parsimony than those without QOL metrics. Physical health was a stronger predictor of mortality than mental health. The findings support the incorporation of QOL metrics into prognostic models and patient counseling for RCC.

Abstract
Transperineal prostate biopsy carries a significantly lower risk of infectious complications compared with the transrectal approach. We provide a step-by-step description of our current procedural technique for performing transperineal prostate biopsy under local anesthesia. A key component of our technique is the use of a disposable, probe-mounted needle guide that minimizes the number punctures to the perineal skin and allows for continuous needle visualization throughout the procedure. We have paired this device with a novel fusion biopsy platform that utilizes three-dimensional transrectal ultrasound to enable targeting of suspicious lesions found prebiopsy MRI as well as allows for mapping of biopsy core locations for postprocedure review and use at the time of subsequent prostate biopsy or ablation procedures.

Abstract
INTRODUCTION The role of renal biopsy prior to surgical intervention for a renal mass remains controversial despite the fact that for all other urological organs except the testicle, biopsy inevitably precedes treatment as is true for all other specialties dealing with solid masses (e.g. thyroid, breast, colon, liver, etc.). Accordingly, we sought to determine the impact of a routine biopsy regimen on the course of patients with cT1a lesions in comparison with a contemporary series of cT1a individuals who went directly to treatment without a preoperative biopsy. METHODS We analyzed a multi-institutional, prospectively maintained database of patients who underwent an office-based, ultrasound-guided, renal mass biopsy (RMB) for a cT1a renal mass (i.e. ≤4cm in largest dimension). Controls were selected from all patients in the database who had a cT1a renal lesion but did not undergo RMB. Both groups were analyzed for differences in treatment modality and surgical pathology results. RESULTS A total of 72 RMB and 73 control patients were analyzed. The groups were similar in regards to their baseline characteristics. Overall RMB diagnostic rate was 75%. Surgical pathology revealed that excision of benign tumors was eight-fold less in the RMB cohort compared to the control group (3% vs. 23%; P < 0.001). Additionally, the rate of active surveillance in the RMB cohort was nearly three times higher at 35% vs. 14% for the controls (P < 0.001). Biopsy was concordant with surgical pathology in 97% of cases for primary histology (i.e. benign vs. malignant), 97% for histologic subtype, and 46% for low (I or II) vs. high (III or IV) grade. On multivariate analysis patients who underwent surgical intervention without preoperative RMB were 6.7 times more likely to have benign histopathology compared to patients who underwent preoperative RMB (OR 6.7, 95% CI = 0.714 - 63.626, P = 0.096). There were no procedural or post-procedural RMB complications. CONCLUSIONS For patients with cT1a lesions, the implementation of routine office-based RMB led to a significant decrease in the rate of surgical intervention for benign tumors. This practice also resulted in a higher rate of active surveillance for the management of renal cortical neoplasms with benign histopathology compared to a control group.

Abstract
OBJECTIVE To evaluate outcomes for patients with local recurrence (LR) of clinically localized renal cell carcinoma (RCC) without concurrent systemic metastasis from our institution, an event that occurs rarely (1%-3%) after surgery. LR may be a harbinger of poor outcomes, and the best management of these patients is unclear. MATERIALS/METHODS We retrospectively reviewed patients surgically treated for clinically localized RCC (cT1-2N0M0) with subsequent LR (in the partial or radical nephrectomy bed) and/or regional recurrence (RR; in the abdomen distant from the direct site of surgery) without concurrent metastasis from our institutional database (2004-2018). Comparative and survival analyses were performed. RESULTS Out of 3038 total patients, 1895 had clinically localized RCC, with 30 patients (1.6%) having isolated LR/RR. Median time to recurrence was 26.5 months (IQR:16-35). Of 26 patients treated with local therapy, 14 (53.8%) recurred over a median follow-up time of 29.5 months (IQR:12-45). The 1-year and 2-year secondary recurrence-free survival rates are 60.7% and 49.7%, respectively. Two or more sites of locoregional recurrence significantly predicted secondary recurrence/metastasis after local therapy for local recurrence (hazard ratio: 2.22, P= .04). CONCLUSION Our results suggest local therapy is appropriate for select patients with LR/RR, with almost 50% of patients undergoing a second local therapy remaining alive with "local cure" and no secondary recurrence. The number of sites of recurrence can be used to better select patients that will benefit from local therapy or systemic/combination therapy. This work provides a framework onto which further studies regarding local therapy and locoregional recurrence of RCC can be performed.

Abstract
T-cell receptor sequencing (TCRseq) enables tracking of T-cell clonotypes recognizing the same antigen over time and across biological compartments. TCRseq has been used to test if cross-reactive antitumor T cells are responsible for development of immune-related adverse events (irAEs) following immune checkpoint blockade. Prior studies have interpreted T-cell clones shared among the tumor and irAE as evidence supporting this, but interpretations of these findings are challenging, given the constraints of TCRseq. Here we capitalize on a rare opportunity to understand the impact of potential confounders, such as sample size, tissue compartment, and collection batch/timepoint, on the relative proportion of shared T-cell clones between an irAE and tumor specimens. TCRseq was performed on tumor-involved and -uninvolved tissues, including an irAE, that were obtained throughout disease progression and at the time of rapid autopsy from a patient with renal cell carcinoma treated with programmed death-1 (PD-1) blockade. Our analyses show significant effects of these confounders on our ability to understand T-cell receptor overlap, and we present mitigation strategies and study design recommendations to reduce these errors. Implementation of these strategies will enable more rigorous TCRseq-based studies of immune responses in human tissues, particularly as they relate to antitumor T-cell cross-reactivity in irAEs following checkpoint blockade.

Abstract
Perirectal spacer placement minimizes the risk of bowel toxicity from prostate radiation therapy. We show that a novel probe-mounted needle guide can be safely used for perirectal spacer insertion. The main advantage of this device is that it ensures needle visualization throughout the procedure.
In this report we describe our successful adoption of a single-use, probe-mounted, needle guide for perirectal hydrogel spacer placement prior to radiation therapy for prostate cancer. Use of this device eliminates the need for a mechanical stepper unit and facilitates perirectal hydrogel placement by ensuring alignment of the injection needle with the ultrasound probe.

Abstract
PURPOSE Provider and hospital factors influence healthcare quality, but data are lacking to assess their impact on renal cancer surgery. We aimed to assess factors related to surgeon and hospital volume and study their impact on 30-day outcomes after radical nephrectomy. MATERIALS AND METHODS Renal surgery data were abstracted from Maryland's Health Service Cost Review Commission from 2000 to 2018. Patients ≤18 years old, without a diagnosis of renal cancer, and concurrently receiving another major surgery were excluded. Volume categories were derived from the mean annual cases distribution. Multivariable logistic and linear regression models assessed the association of volume on length of stay, intensive care days, cost, 30-day mortality, readmission, and complications. RESULTS 7,950 surgeries, completed by 573 surgeons at 48 hospitals, were included. Demographic, surgical, and admission characteristics differed between groups. Radical nephrectomies performed by low volume surgeons demonstrated increased post-operative complication frequency, mortality frequency, length of stay, and days spent in intensive care relative to other groups. However, after logistic regression adjusting for clinical risk and socioeconomic factors, only increased length of stay and ICU days remained associated with lower surgeon volume. Similarly, after adjusted logistic regression, hospital volume was not associated with the studied outcomes. CONCLUSIONS Surgeons and hospitals differ in regards to patient demographic and clinical factors. Barriers exist regarding access to high-volume care, and thus some volume-outcome trends may be driven predominantly by disparities and case mix.

Abstract
[111 In]In-XYIMSR-01 is a promising single-photon emission computed tomography (SPECT) imaging agent for identification of tumors that overexpress carbonic anhydrase IX. To translate [111 In]In-XYIMSR-01 to phase I trials, we performed animal toxicity and dosimetry studies, determined the maximum dose for human use, and completed the chemistry, manufacturing, and controls component of a standard regulatory application. The production process, quality control testing, stability studies, and specifications for sterile drug product release were based on United States Pharmacopeia chapters <823> and <825>, FDA 21 CFR Part 212. Toxicity was evaluated by using nonradioactive [113/115 In]In-XYIMSR-01 according to 21 CFR Part 58 guidelines. Organ Level INternal Dose Assessment/EXponential Modeling (OLINDA/EXM) was used to calculate the maximum single dose for human studies. Three process validation runs at starting radioactivities of ~800 MBq were completed with a minimum concentration of 407 MBq/ml and radiochemical purity of ≥99% at the end of synthesis. A single intravenous dose of 55 μg/ml of [113/115 In]In-XYIMSR-01 was well tolerated in male and female Sprague-Dawley rats. The calculated maximum single dose for human injection from dosimetry studies was 390.35 MBq of [111 In]In-XYIMSR-01. We have completed toxicity and dosimetry studies as well as validated a manufacturing process to test [111 In]In-XYIMSR-01 in a phase I clinical trial.

Abstract
TPS4596 Background: There is no standard adjuvant systemic therapy that increases overall survival (OS) over surgery alone for non-metastatic RCC. Anti-PD-1 nivolumab (nivo) improves OS in metastatic RCC and is well tolerated. In mouse models, priming the immune system prior to surgery with anti-PD-1 results in superior OS compared to adjuvant dosing. Remarkable pathologic responses have been seen with neoadjuvant PD-1 in multiple ph 2 studies in bladder, lung and breast cancers. Phase 2 neoadjuvant RCC trials of nivo show preliminary feasibility and safety with no surgical delays. PROSPER RCC seeks to improve clinical outcomes by priming the immune system with neoadjuvant nivo prior to nephrectomy followed by continued immune system engagement with adjuvant blockade in patients (pts) with high risk RCC compared to standard of care surgery alone. Methods: This global, unblinded, phase 3 National Clinical Trials Network study is accruing pts with clinical stage ≥T2 or TanyN+ RCC of any histology planned for radical or partial nephrectomy. Select oligometastatic disease is permitted if the pt can be rendered ‘no evidence of disease’ within 12 weeks of nephrectomy (≤3 metastases; no brain, bone or liver). In the investigational arm, nivo is administered 480mg IV q4 weeks with 1 dose prior to surgery followed by 9 adjuvant doses. The control arm is nephrectomy followed by standard of care surveillance. There is no placebo. Baseline tumor biopsy is required only in the nivo arm but encouraged in both. Randomized pts are stratified by clinical T stage, node positivity, and M stage. 805 pts provide 84.2% power to detect a 14.4% absolute benefit in recurrence-free survival at 5 years assuming the ASSURE historical control of ̃56% to 70% (HR = 0.70). The study is powered to evaluate a significant increase in OS (HR 0.67). Critical perioperative therapy considerations such as safety, feasibility, and quality of life metrics are integrated. PROSPER RCC embeds a wealth of translational studies to examine the contribution of the baseline immune milieu and neoadjuvant priming with anti-PD-1 on clinical outcomes. As of February 10, 2021, 704 patients have been enrolled (N = 805). Clinical trial information: NCT03055013.

Abstract
OBJECTIVE To assess the quality and accuracy of online videos about the medical management of nephrolithiasis. MATERIALS AND METHODS To evaluate trends in online interest, we first examined the frequency of worldwide YouTube searches for 'kidney stones' from 2015 to 2020. We then queried YouTube with terms related to symptoms and treatment of kidney stones and analysed English-language videos with >5000 views. Quality was assessed using the validated DISCERN instrument. Evidence-based content analysis of video content and viewer comments was performed. RESULTS Online searches for videos about kidney stones doubled between 2015 and 2019 (P < 0.001). We analysed 102 videos with a median (range) number of views of 46 539 (5024-3 631 322). The mean (sd) DISCERN score was 3.0 (1.4) out of 5, indicating 'moderate' quality; scores were significantly higher for the 21 videos (21%) authored by academic hospitals (mean 3.7 vs 2.8, P = 0.02). Inaccurate or non-evidence-based claims were identified in 23 videos (23%); none of the videos authored by academic institutions contained inaccurate claims. Videos with inaccurate statements had more than double the viewer engagement (viewer-generated comments, 'thumbs up' and 'thumbs down' ratings) compared to videos without inaccuracies (P < 0.001). Among viewer comments, 43 videos (43%) included comments with inaccurate or non-evidence-based claims, and a large majority (82 videos, 80%) had 'chatbot' recommendations. CONCLUSIONS Interest in YouTube videos about nephrolithiasis has doubled since 2015. While highly viewed videos vary widely in quality and accuracy, videos produced by academic hospitals have significantly fewer inaccurate claims. Given the high prevalence of stone disease and poor-quality videos, patients should be directed to evidence-based content online.

Abstract
PURPOSE To evaluate the association of post-RP drain placement with post-operative complications and opioid use at a high-volume institution. METHODS A prospective, comparative cohort study of patients undergoing robot-assisted or open RP was conducted. Patients for two surgeons did not routinely receive pelvic drains ("No Drain" arm), while the remainder routinely placed drains ("Drain" arm). Outcomes were evaluated at 30 days including Clavien-Dindo complications and opioid use. Intention-to-treat primary analysis and additional secondary analyses were performed using appropriate statistical tests and logistic regression. RESULTS Of 498 total patients, 144 (28.9%) were in the No Drain arm (all robot-assisted) and 354 (71.1%) in the Drain arm. In the No Drain arm, 19 (13.2%) intraoperatively were chosen to receive drains. There was no difference in overall or major (Clavien ≥ 3) complications between groups (p = 0.2 and 0.4, respectively). Drain deferral did not predict complications on multivariable analysis adjusted for age, BMI, comorbidities, clinical risk, surgical approach, operating time, lymphadenectomy, and number of nodes removed [OR 0.61, 95% CI 0.34-1.11, p = 0.10]; nor did it predict symptomatic fluid collection, adjusting for lymphadenectomy and nodes removed [OR 1.14, 95% CI 0.43-3.60, p = 0.8]. Drain deferral did not decrease opioid use (p = 0.5). Per protocol analysis and restriction to robot-assisted cases demonstrated similar results. CONCLUSION There was no difference in adverse events, complications, symptomatic collections, or opioid use with deferral of routine drain placement after RP. Experienced surgeons may safely defer drain placement in the majority of robot-assisted RP cases.

Abstract
OBJECTIVE To perform an early comparative study of outcomes between single-port and robot-assisted laparoscopic radical prostatectomy (SP-RALRP) and standard RALRP at our institution and pooled analysis of series to date. PATIENTS AND METHODS Patients with organ-confined prostate cancer undergoing SP-RALRP at a high-volume institution were identified retrospectively along with reported SP-RALRP series to date. Data were compared to a contemporary prospective cohort of men undergoing standard RALRP. Patient demographics, perioperative and postoperative data, and complications categorized by the Clavien-Dindo system were compared for the institutional and pooled SP-RALRP cohorts to standard RALRP. RESULTS A total of 208 SP-RALRP cases were identified (26 from our institution) and compared to 376 standard RALRP cases. In the institutional analysis, there was no difference in operative time, length of stay, overall complications (15.4% vs 17.3%, P= 1.0), major (Clavien ≥III) complications (3.8% vs 3.7%, P = .6), inpatient opioid use, or patient-reported pain scores; median estimated blood loss (100 mL vs 150 mL, P = .02) and number of lymph nodes removed (5.5 vs 9, P = .002) were lower for SP-RALRP. In the pooled analysis, 208 patients receiving SP-RALRP had similar estimated blood loss and complication rates but fewer lymph nodes removed (P = .02) and marginally longer operating time (+16 minutes, P = .01) compared to standard RALRP. The difference in rate of positive surgical margins was not statistically significant (31.3% vs 24.5%, P = .08). CONCLUSION Based on an early experience with SP-RALRP at a high-volume center and a pooled analysis of SP series to date, perioperative and pathologic outcomes appear nearly equivalent compared to standard RALRP.

Abstract
OBJECTIVE To evaluate perioperative complications for open radical prostatectomy (ORP) and robot-assisted RP (RARP) for patients enrolled in the PREvention of VENous ThromboEmbolism Following Radical Prostatectomy (PREVENTER; ClinicalTrials.gov Identifier: NCT03006562) trial, to determine predictors and impact on opioid consumption. PATIENTS AND METHODS A prospective cohort of 500 patients undergoing ORP and RARP was followed to determine rates of complications and opioid use. Complications were classified 30 days after RP using the Clavien-Dindo system. Patient characteristics and outcomes were compared using appropriate statistical tests. Logistic and linear regressions were performed to identify predictors of complications and evaluate the relationship between complications and postoperative opioid use. RESULTS A total of 124 (24.8%) men underwent ORP and 376 (75.2%) RARP, with 418 (83.6%) receiving pelvic lymph node dissection (PLND). While 83 patients (16.6%) had complications, only 19 (3.8%) were major (Clavien-Dindo Grade ≥III), with no differences by surgical approach. PLND (odds ratio [OR] 2.96, 95% confidence interval [CI] 1.25-8.71; P = 0.03) and Stage pT3b (OR 2.76, 95% CI 1.23-6.00;P = 0.01) were the only predictors of complications after controlling for potential confounders. Patients who had complications had greater inpatient (P = 0.02) and outpatient (P = 0.005) opioid use, which persisted after controlling for patient-reported pain, attending surgeon variation, surgical approach, and undergoing PLND (inpatient β:77.2, 95% CI 17.9-136.5,P = 0.03; and outpatient β:21.9, 95% CI 4.7-39.1,P = 0.01). CONCLUSION In an analysis of prospectively collected data, overall and major complications rates did not differ by surgical approach. Patients receiving PLND and with Stage pT3b disease had more complications. Complications were independently associated with higher inpatient and outpatient postoperative opioid use.

Abstract
INTRODUCTION The clinical course of Prostate cancer (PCa) are markedly diverse, ranging from indolent to highly aggressive disseminated disease. Molecular imaging techniques are playing an increasing role in early PCa detection, staging and disease recurrence. There are some molecular imaging modalities, radiotracers agents and its performance are important in current clinical practice PCa. OBJECTIVE This review summarizes the latest information regarding molecular imaging of PCa and is designed to assist urologists with ordering and interpreting these modalities and different radiotracers for different patients. EVIDENCE ACQUISITION A PubMed-based literature search was conducted up to September 2019. We selected the most recent and relevant original articles, metanalysis and reviews that have provided relevant information to guide molecular imaging modalities and radiotracers use. EVIDENCE SYNTHESIS In this review, we discuss 3 main molecular imaging modalities and 7 radiotracer technologies available. CONCLUSIONS The use molecular imaging modalities and radiotracers has a unique role in biochemical recurrence and diagnosis of ganglionar and bone progression of PCa. In the present time, no one of these molecular imaging modalities can be recommended over the classical work-up of abdominopelvic CT scan and bone scan, and large-scale and multi-institutional studies are required to validate the efficacy and cost utility of these new technologies.

Meckel's diverticulum is the most common congenital malformation of the gastrointestinal tract. In this report, we present a patient with a Meckel's diverticulum that was incidentally discovered on prostate-specific membrane antigen positron emission tomography/computed tomography (PSMA PET/CT) imaging performed for prostate cancer staging. We discuss hypotheses for why the Meckel's diverticulum showed high uptake of PSMA-targeted radiotracer and the clinical implications of this finding.

Abstract
The role for cytoreductive nephrectomy (CN) in the treatment of metastatic renal cell carcinoma (mRCC) has evolved with advancements in systemic therapy. During the cytokine-based immunotherapy era, CN provided a clear survival benefit and was considered standard of care in management of mRCC. The development of targeted systemic therapy directed at the vascular endothelial growth factor pathway altered the treatment paradigm and accentuated the importance of risk stratification in treatment selection. This article reviews the literature evaluating the benefit of CN during the evolution of systemic therapy and provides clinical recommendations for current utilization of CN in patients with mRCC.

Abstract
To evaluate the outcomes of total eradication therapy (TET), designed to eradicate all sites of visible cancer and micrometastases, in men with newly diagnosed oligometastatic prostate cancer (OMPCa). Men with ≤ 5 sites of metastases were enrolled in a prospective registry study, underwent neoadjuvant chemohormonal therapy, followed by radical prostatectomy, adjuvant radiation (RT) to prostate bed/pelvis, stereotactic body radiation therapy (SBRT) to oligometastases, and adjuvant hormonal therapy (HT). When possible, the prostate-specific membrane antigen targeted 18F-DCFPyL PET/CT (18F-DCFPyL) scan was obtained, and abiraterone was added to neoadjuvant HT. Twelve men, median 55 years, ECOG 0, median PSA 14.7 ng/dL, clinical stages M0—1/12 (8%), M1a—3/12 (25%) and M1b—8/12 (67%), were treated. 18F-DCFPyL scan was utilized in 58% of cases. Therapies included prostatectomy 12/12 (100%), neoadjuvant [docetaxel 11/12 (92%), LHRH agonist 12/12 (100%), abiraterone + prednisone 6/12 (50%)], adjuvant radiation [RT 2/12 (17%), RT + SBRT 4/12 (33%), SBRT 6/12 (50%)], and LHRH agonist 12/12 (100%)]. 2/5 (40%) initial patients developed neutropenic fever (NF), while 0/6 (0%) subsequent patients given modified docetaxel dosing developed NF. Otherwise, TET resulted in no additive toxicities. Median follow-up was 48.8 months. Overall survival was 12/12 (100%). 1-, 2-, and 3-year undetectable PSA’s were 12/12 (100%), 10/12 (83%) and 8/12 (67%), respectively. Median time to biochemical recurrence was not reached. The outcomes suggest TET in men with newly diagnosed OMPCa is safe, does not appear to cause additive toxicities, and may result in an extended interval of undetectable PSA.

Abstract
TPS5101 Background: There is no standard adjuvant systemic therapy that increases overall survival (OS) over surgery alone for non-metastatic RCC. Anti-PD-1 nivolumab (nivo) improves OS in metastatic RCC and is well tolerated. In mouse models, priming the immune system prior to surgery with anti-PD-1 results in superior OS compared to adjuvant dosing. Remarkable pathologic responses have been seen with neoadjuvant PD-1 in multiple ph 2 studies in bladder, lung and breast cancers. Phase 2 neoadjuvant RCC trials of nivo show preliminary feasibility and safety with no surgical delays. PROSPER RCC seeks to improve clinical outcomes by priming the immune system with neoadjuvant nivo prior to nephrectomy followed by continued immune system engagement with adjuvant blockade in patients (pts) with high risk RCC compared to standard of care surgery alone. Methods: This global, unblinded, phase 3 National Clinical Trials Network study is accruing pts with clinical stage ≥T2 or TanyN+ RCC of any histology planned for radical or partial nephrectomy. Select oligometastatic disease is permitted if the pt can be rendered ‘no evidence of disease’ within 12 weeks of nephrectomy (≤3 metastases; no brain, bone or liver). In the investigational arm, nivo is administered 480mg IV q4 weeks with 1 dose prior to surgery followed by 9 adjuvant doses. The control arm is nephrectomy followed by standard of care surveillance. There is no placebo. Baseline tumor biopsy is required only in the nivo arm but encouraged in both. Randomized pts are stratified by clinical T stage, node positivity, and M stage. 805 pts provide 84.2% power to detect a 14.4% absolute benefit in recurrence-free survival at 5 years assuming the ASSURE historical control of ~56% to 70% (HR = 0.70). The study is powered to evaluate a significant increase in OS (HR 0.67). Critical perioperative therapy considerations such as safety, feasibility, and quality of life metrics are integrated. PROSPER RCC embeds a wealth of translational studies to examine the contribution of the baseline immune milieu and neoadjuvant priming with anti-PD-1 on clinical outcomes. As of February 2020, 396 patients have been enrolled. Clinical trial information: NCT03055013 .

Abstract
BACKGROUND Direct high-quality evidence is lacking evaluating perioperative pharmacologic prophylaxis (PP) after radical prostatectomy (RP) to prevent venous thromboembolism (VTE) leading to significant practice variation. OBJECTIVE To study the impact of in-hospital PP on symptomatic VTE incidence and adverse events after RP at 30 d, with the secondary objective of evaluating overall VTE in a screening subcohort. DESIGN, SETTING, AND PARTICIPANTS A prospective, phase 4, single-center, randomized trial of men with prostate cancer undergoing open or robotic-assisted laparoscopic RP was conducted (July 2017-November 2018). INTERVENTION PP (subcutaneous heparin) plus routine care versus routine care alone. The screening subcohort was offered lower extremity duplex ultrasound at 30 d. OUTCOMES MEASUREMENTS AND STATISTICAL ANALYSIS The primary efficacy outcome was symptomatic VTE incidence (pulmonary embolism [PE] or deep venous thrombosis [DVT]). Primary safety outcomes included the incidence of symptomatic lymphocele, hematoma, or bleeding after surgery. Secondary outcomes were overall VTE, estimated blood loss, total surgical drain output, complications, and surveillance imaging bias. Fisher's exact test and modified Poisson regression were performed. RESULTS AND LIMITATIONS A total of 501 patients (75% robotic) were randomized and >99% (500/501) completed follow-up. At second interim analysis (N = 445), the symptomatic VTE rate was 2.3% (four PE + DVT and one DVT) for routine care versus 0.9% (one PE + DVT and one DVT) for PP (relative risk 0.40 [95% confidence interval 0.08-2.03], p = 0.3) meeting a futility threshold for early stopping. In the screening subcohort, the overall VTE rate was 3.3% versus 2.4% (p = 0.7). Results were similar at the final analysis (symptomatic VTE: 2.0% vs 0.8%, p = 0.3; overall VTE: 2.9% vs 2.8%, p = 1). No differences were observed in safety or secondary outcomes. All VTE events (seven symptomatic and three asymptomatic) occurred in patients undergoing pelvic lymph node dissection. CONCLUSIONS This study was not able to demonstrate a statistically significant reduction in symptomatic VTE associated with PP. There was no increase in the development of symptomatic lymphoceles, bleeding, or other adverse events. Given that the event rate was lower than powered for, further research is needed among high-risk patients (Caprini score ≥8) or patients receiving pelvic lymph node dissection. PATIENT SUMMARY In this report, we randomized patients undergoing radical prostatectomy to perioperative pharmacologic prophylaxis or routine care alone. We found that pharmacologic prophylaxis did not reduce postoperative symptomatic venous thromboembolism significantly for men at routine risk. Importantly, pharmacologic prophylaxis did not increase adverse events, such as formation of lymphoceles or bleeding, and can safely be implemented when indicated for patients with risk factors undergoing radical prostatectomy.

Abstract
Open retroperitoneal lymph node dissection (RPLND) is the gold standard for surgical management of the retroperitoneum in patients with testicular cancer, and is associated with excellent oncologic outcomes and significant morbidity including length of stay. Minimally invasive RPLND, starting with laparoscopic retroperitoneal lymph node dissection in 1992 and now robotic retroperitoneal lymph node dissection in 2006, endeavor to decrease the morbidity of open RPLND while maintaining excellent oncologic outcomes. This review surveys the literature regarding both primary and post-chemotherapy robotic RPLND, emphasizing that while early outcomes are promising, much work needs to be done before widespread use of this technique is implemented.

Abstract
PURPOSE Previous studies suggest that androgen deprivation therapy (ADT) promotes antitumor immunity in prostate cancer. Whether a vaccine-based approach can augment this effect remains unknown. PATIENTS AND METHODS We conducted a neoadjuvant, randomized study to quantify the immunologic effects of a GM-CSF-secreting allogeneic cellular vaccine in combination with low-dose cyclophosphamide (Cy/GVAX) followed by degarelix versus degarelix alone in patients with high-risk localized prostate adenocarcinoma who were planned for radical prostatectomy. RESULTS Both Cy/GVAX plus degarelix and degarelix alone led to significant increases in intratumoral CD8+ T-cell infiltration and PD-L1 expression as compared with a cohort of untreated, matched controls. However, the CD8+ T-cell infiltrate was accompanied by a proportional increase in regulatory T cells (Treg), suggesting that adaptive Treg resistance may dampen the immunogenicity of ADT. Although Cy/GVAX followed by degarelix was associated with a modest improvement in time-to-PSA progression and time-to-next treatment, as well as an increase in PD-L1, there was no difference in the CD8+ T-cell infiltrate as compared with degarelix alone. Gene expression profiling demonstrated that CHIT1, a macrophage marker, was differentially upregulated with Cy/GVAX plus degarelix compared with degarelix alone. CONCLUSIONS Our results highlight that ADT with or without Cy/GVAX induces a complex immune response within the prostate tumor microenvironment. These data have important implications for combining ADT with immunotherapy. In particular, our finding that ADT increases both CD8+ T cells and Tregs supports the development of regimens combining ADT with Treg-depleting agents in the treatment of prostate cancer.

Abstract
Abstract
In recent years, immunotherapy has become one of the most exciting and promising avenues to cancer treatment. Treatment with immune checkpoint inhibitors has managed to produce long-term remission of solid tumors in many patients. However, patients who respond well to such treatment are often a minority; this is particularly the case with some cancers such as renal cell carcinoma, non-small cell lung cancer, and glioblastoma, where many patients either derive no benefit or only a short-term benefit. In this analysis, we examined gene expression data from RNA sequencing experiments that compared tumor-infiltrating lymphocytes (TIL) with paired circulating lymphocytes from patients with renal cell carcinoma (RCC), bladder cancer (BLCA), prostate cancer (PRAD), and glioblastoma (GBM). Our analysis helped to characterize global CD4 and CD8 TIL gene expression patterns among these four cohorts. Further, using the expression profiles for known immune checkpoint markers PD-1, TIM-3, and LAG-3 in CD8 cells, we dichotomized the patient samples into potential checkpoint inhibitor responder and nonresponder groups. This model was then used to identify other genes that are associated with CD8 TIL exhaustion, which may lead to the identification of cytokines useful in discovering specific therapeutic targets.

Abstract
Schwannomas of the prostate are exceedingly rare. We present a noteworthy case of a sporadic prostatic schwannoma diagnosed in conjunction with prostatic adenocarcinoma. A 60-year-old male presented with mild lower urinary tract symptoms and a prostate specific antigen (PSA) level of 4.84 ng/mL. A transrectal ultrasound guided prostate biopsy revealed multifocal Grade Group 2 prostate cancer. MRI demonstrated a PI-RADS 4 lesion and a periprostatic cystic lesion. Prostatectomy was performed. Final pathology demonstrated prostatic adenocarcinoma, with a separate periprostatic schwannoma. We present the first case in the literature of a sporadic periprostatic schwannoma discovered during evaluation for prostatic adenocarcinoma.

Abstract
Among the more notable immunotherapies are checkpoint inhibitors, which prevent suppressive signaling on T cells, thereby (re)activating them to kill tumor cells. Despite remarkable treatment responses to immune checkpoint blockade, with a subset of patients achieving complete responses, a large population have little-to-no response, dictating the necessity of further research in this field. Myeloid derived cells heavily infiltrate the tumor microenvironment (TME) of many cancers and are believed to have a number of potent anti-inflammatory effects. Here we use primary non-metastatic renal cell carcinoma to interrogate the gene expression profiles of M2-tumor associated macrophages (M2-TAMs). We performed Fluorescent Activated Cell (FACS) sorting on monocytes from the peripheral blood and tumors of fresh clear cell renal cell carcinoma (ccRCC) samples obtained after patients underwent a partial (7 patients-87.5%) or radical (1 patient-12.5%) nephrectomy. We then utilized NanoString gene expression profiling to show that TAMs express a heterogeneous transcriptional profile that does not cleanly fit into the traditional M1-M2 TAM paradigm. We identified expression of M1 associated costimulatory molecules, a multitude of diverse chemokines, canonical M2 associated molecules, as well as factors involved in the Complement system and checkpoint receptors. Our data are in agreement with other published literature investigating TAMs in various non-ccRCC TMEs, and support the growing literature concerning expression of Complement factors and checkpoint receptors on TAMs.

Abstract
610 Background: Personalized treatment for clinical T1 renal cortical masses (RCMs) should account for competing risks related to tumor and patient characteristics. Using a contemporary multi-institutional cohort, we developed treatment-specific prediction models for cancer-specific mortality (CSM), other-cause mortality (OCM), and 90-day complication rates for patients managed with surgery, thermal ablation (TA), and active surveillance (AS). Methods: Preoperative clinical and radiological features were collected for eligible patients aged 18-91 years treated at four academic centers from 2000-2016. Prediction models used competing risks regressions for CSM and OCM and logistic regressions for 90-day Clavien >3 complications, adjusting for tumor size as well as patient age, sex, ECOG performance status (PS), and Charlson comorbidity index (CCI). Predictions accounted for missing data using multiple imputation. Results: After excluding 25 patients with no follow-up, the cohort included 4995 patients treated with radical nephrectomy (RN, n=1270), partial nephrectomy (PN, n=2842), thermal ablation (n=479), or active surveillance (n=404). Median follow-up was 5.1 years (IQR 2.5-8.5). Predictions from the fitted model are shown in an online calculator ( https://rgulati.shinyapps.io/rcc-risk-calculator ). To illustrate the use of this calculator for a specific patient, a 70-year-old female with a 5.5 cm RCM, PS of 2, and CCI of 3 has a predicted 5-year CSM of 4-7% across treatments, 5-year OCM of 34-49%, and 90-day risk of Clavien ≥3 complications of 4%, 10%, and 6% for RN, PN, and TA respectively. Conclusions: Personalized treatment selection for cT1 RCM is challenging. We present a competing risk calculator that incorporates pretreatment features to quantify competing causes of mortality and treatment-associated complications. Pending validation, this tool may be used in clinical practice to provide patients with estimated individualized treatment-specific probabilities of competing causes of death and complication risks to facilitate shared decision-making.

Abstract
TPS765 Background: There is no standard adjuvant systemic therapy that increases overall survival (OS) over surgery alone for non-metastatic RCC. Anti-PD-1 nivolumab (nivo) improves OS in metastatic RCC and is well tolerated. In mouse models, priming the immune system prior to surgery with anti-PD-1 results in superior OS compared to adjuvant dosing. Remarkable pathologic responses have been seen with neoadjuvant PD-1 in multiple ph 2 studies in bladder, lung and breast cancers. Phase 2 neoadjuvant RCC trials of nivo show preliminary feasibility and safety with no surgical delays. PROSPER RCC seeks to improve clinical outcomes by priming the immune system with neoadjuvant nivo prior to nephrectomy followed by continued immune system engagement with adjuvant blockade in patients (pts) with high risk RCC compared to standard of care surgery alone. Methods: This global, unblinded, phase 3 National Clinical Trials Network study is accruing pts with clinical stage ≥T2 or TanyN+ RCC of any histology planned for radical or partial nephrectomy. Select oligometastatic disease is permitted if the pt can be rendered ‘no evidence of disease’ within 12 weeks of nephrectomy (≤3 metastases; no brain, bone or liver). In the investigational arm, nivo is administered 480mg IV q4 weeks with 1 dose prior to surgery followed by 9 adjuvant doses. The control arm is nephrectomy followed by standard of care surveillance. There is no placebo. Baseline tumor biopsy is required only in the nivo arm but encouraged in both. Randomized pts are stratified by clinical T stage, node positivity, and M stage. 805 pts provide 84.2% power to detect a 14.4% absolute benefit in recurrence-free survival at 5 years assuming the ASSURE historical control of ~56% to 70% (HR = 0.70). The study is powered to evaluate a significant increase in OS (HR 0.67). Critical perioperative therapy considerations such as safety, feasibility, and quality of life metrics are integrated. PROSPER RCC embeds a wealth of translational studies to examine the contribution of the baseline immune milieu and neoadjuvant priming with anti-PD-1 on clinical outcomes. As of October 18, 2019, 317 patients have been enrolled. Clinical trial information: NCT03055013.

Abstract
350 Background: Ductal prostate adenocarcinoma (DAC) is an aggressive variant of prostate cancer (PC). We aimed to assess the outcomes of men with localized DAC undergoing radical prostatectomy (RP) or external beam radiotherapy (RTx) compared to acinar adenocarcinoma of the prostate (PAC) and investigate any difference between these treatment modalities. Methods: All patients presenting to our institution with localized DAC from January 2005 - November 2018 were compared to a pooled cohort of patients from 3 tertiary referral centers who underwent RP for Gleason 8 PC and a cohort of high risk PC patients who underwent RTx for PAC. Patient, tumor characteristics and outcome data were analyzed. Results: 257 men with DAC were identified and compared to 803 with PAC. 203 men with DAC and 729 men with PAC underwent RP while 54 men with DAC and 74 men with PAC underwent RTx. Men with DAC were older (65 vs 63 years and 70.5 vs 66 years) and had higher cT3/T4 stage (43% vs 2.8% and 44.5% vs 31.1%) in both groups, respectively (all p <0.05). The median follow-up for men undergoing RP was 34 (range 0.9 to 177) months and 73.4 (range 0.6 – 224.2) months for men having RTx. Presence of DAC was an independent risk factor for metastases (HR 2.5 (95% CI 1.4- 4.8); p<0.01) and death (HR 2.3 (95% CI 1.1 – 4.7); p=0.02) following RP. The 3- year overall survival (OS) rates for DAC and PAC in men undergoing RP were 93.3% vs 99.3% (p<0.01). On adjusting for Gleason score, clinical T stage, PSA and age, DAC was also an independent risk factor for death (HR 6.1 (95% CI 1.7-22.2); p<0.01) in men undergoing RTx with 5-year OS rates of 100% and 81.6% for DAC and PAC, respectively. There was no difference in the OS of men with DAC between RP and RTx. Conclusions: Men undergoing RP or RTx for localized DAC had worse outcomes compared to PAC, but no survival difference was seen between these treatment modalities. DAC behaves clinically differently than PAC. Further evaluation of the underlying biology and potential for specific targeted multimodality therapies in DAC is needed.

Abstract
BACKGROUND A proportion of men with grade group (GG) 2 intermediate risk (IR) prostate cancer are downgraded to GG1 or harbor favorable pathology (FP, defined as GG1 or GG2 with <5% Gleason pattern 4) at radical prostatectomy (RP). Prediction of downgrading or FP may help identify potential active surveillance candidates within this group that have outcomes similar to biopsy low-risk (LR) disease. METHODS We performed a comparative cohort study of biopsy LR and IR men who underwent RP at The Johns Hopkins Hospital and Bayview Medical Center between 2005 and 2018. We evaluated pathological outcomes at RP and recurrence-free survival (RFS). Multivariable logistic regression and Cox proportional hazards regression were applied and individual predicted probabilities were calculated. RESULTS Among 2943 biopsy GG2 IR patients, 223 (7.6%) were downgraded to GG1, while 525 (17.8%) had FP; 730 of 1325 biopsy LR patients (55.1%) were upgraded (GG >1). Concordance statistics for final predictive regression models were 0.76 for downgrading and 0.70 for upgrading. Biopsy GG2 IR patients downgrading to GG1 or harboring FP had similar RFS to biopsy LR patients. A cutoff of >10% predicted probability of downgrading (24.7% of patients; hazard ratio [HR], 1.55; 95% CI, 0.89-2.68) or >20% predicted probability of FP (37.0% of patients; HR, 1.35; 95% CI, 0.81-2.24) led to similar RFS to biopsy LR patients. CONCLUSION GG2 IR patients who experience downgrading or harbor FP had similar oncologic outcomes as LR patients. The developed models may serve as tools to inform patients about the risks of pathological downgrading/upgrading and help identify a segment of GG2 IR patients who would consider pursuing active surveillance based on predicted probability cutoffs.

Abstract
PURPOSE Pathologic response assessment of tumor specimens from patients receiving systemic treatment provides an early indication of therapeutic efficacy and predicts long-term survival. Grading systems for pathologic response were first developed for chemotherapy in select tumor types. Immunotherapeutic agents have a mechanism of action distinct from chemotherapy and are being used across a broad array of tumor types. A standardized, universal scoring system for pathologic response that encompasses features characteristic for immunotherapy and spans tumor types is needed. EXPERIMENTAL DESIGN Hematoxylin and eosin-stained slides from neoadjuvant surgical resections and on-treatment biopsies were assessed for features of immune-related pathologic response (irPR). A total of 258 specimens from patients with 11 tumor types as part of ongoing clinical trials for anti-PD-(L)1 were evaluated. An additional 98 specimens from patients receiving anti-PD-(L)1 in combination with other treatments were also reviewed, including those from three additional tumor types. RESULTS Common irPR features (immune activation, cell death, tissue repair, and regression bed) were present in all tumor types reviewed, including melanoma, non-small cell lung, head and neck squamous cell, Merkel cell, and renal cell carcinoma, among others. Features were consistent across primary tumors, lymph nodes, and distant metastases. Specimens from patients treated with anti-PD-(L)1 in combination with another agent also exhibited irPR features. CONCLUSIONS irPR features are consistent across tumor types and treatment settings. Standardized, pan-tumor irPR criteria (irPRC) are defined and associated specimen-handling considerations are described. Future, prospective studies are merited to validate irPRC in larger datasets and to associate pathologic features with long-term patient outcomes.

Abstract
OBJECTIVES To evaluate the effect of a prospective opioid reduction intervention after radical prostatectomy (RP; based on a surgery-specific guideline and education) on post-discharge opioid prescribing, use, disposal, and need for additional opioid medication. PATIENTS AND METHODS A prospective, non-randomised, pre-post interventional trial of patients undergoing RP for prostate cancer (August 2017-November 2018) was conducted as part of the Opioid Reduction Intervention for Open, Laparoscopic, and Endoscopic Surgery (ORIOLES) Initiative. An evidence-based intervention including: a discharge sheet, nursing education, and standardised prescribing guideline, was applied with the primary outcome of total oral morphine equivalents (OMEQ) used after RP. Secondary outcomes included opioid prescribing, opioid disposal, need for additional opioid medication, and presence of incisional/post-surgical abdominal pain at 30 days after RP. RESULTS A total of 214 (Pre-Intervention arm) and 229 (Post-Intervention arm) adult patients were enrolled (100% follow-up). The intervention reduced post-discharge opioid prescribing (from 224.3 to 120.3 mg; -46.4%, P = 0.01), reduced opioid use (from 52.1 to 38.3 mg; -26.5%, P < 0.01), and increased opioid disposal (+13.5%, P < 0.01). Greater prescribing of opioids at discharge, higher body mass index, and use of opioid medication prior to surgery, were independently associated with greater post-discharge opioid use, while history of a chronic pain diagnosis was not statistically significant. In the Post-Intervention cohort, 2.2% of patients needed additional medication for post-surgical pain (0.9% obtained a prescription) and 1.3% initiated long-term use. CONCLUSIONS A prospective, evidence-based intervention reduced post-discharge opioid prescribing and use, while increasing disposal after RP. Risk factors for increased opioid use were identified. The results support expanding the use of evidence-based opioid reduction interventions to other surgical specialties.

Abstract
OBJECTIVE To evaluate the incidence, predictors, and survival for those small renal masses (SRM, solid mass ≤4 cm suspicious for a clinical T1a renal cell carcinoma) that disappear on imaging while undergoing active surveillance (AS). SUBJECTS/PATIENTS AND METHODS The Delayed Intervention and Surveillance for SRM registry prospectively enrolled 739 patients with SRMs. Patients having at least 1 image showing no lesion were considered to have a "disappearing" SRM. Logistic regression assessed predictors of having a disappearing SRM and Kaplan-Meier estimates illustrated relative survival. RESULTS Of 374 patients enrolled in AS, 22 (5.9%) experienced a disappearing SRM. Mean time to tumor disappearance was 2.0 years (SD = 1.9) and 50.0% reappeared on subsequent CT imaging. SRM disappearance, most commonly encountered on ultrasound imaging surveillance, was independently associated with tumors <1 cm on multivariable analysis (OR = 10.6 (95% CI: 1.1-100.3), P = 0.04). Furthermore, patients with disappearing SRMs were healthier than other patients on AS with no compromise in overall survival during follow-up (5-year survival = 100% vs. 73.2%, P = 0.06). CONCLUSIONS Approximately 5% of SRM on AS will disappear during follow-up on surveillance imaging. Most of these represent artifacts of heterogeneous imaging modalities, including ultrasound, and the SRM will reappear on subsequent imaging. Given the indolent nature of these lesions, disappearance events do not require reflex repeat imaging and patients should continue AS with their original surveillance schedule intact. A smaller percentage of patients undergoing AS for a SRM may have a mass the permanently disappears.

Abstract
OBJECTIVE To describe our technique and early results performing transperineal prostate biopsy using cognitive magnetic resonance imaging (MRI)/biplanar ultrasound fusion. Key components of this technique include use of the PrecisionPoint Transperineal Access System (Perineologic, Cumberland, MD) and simultaneous transrectal ultrasound guidance in the axial and sagittal planes. PATIENTS AND METHODS In total, 95 patients (38 studied retrospectively and 57 studied prospectively) underwent a transperineal MRI-targeted prostate biopsy using the technique detailed in this manuscript. All biopsies were performed by a single urologist (MAG). Data were collected with respect to cancer detection rates, tolerability, and complications. The subset of patients who were studied prospectively was assessed for complications by telephone interviews performed at 4-6 days and 25-31 days following the prostate biopsy. RESULTS Between February 2018 and June 2019, 95 men underwent a transperineal prostate biopsy using MRI/biplanar ultrasound fusion guidance. Patients had a total of 124 PI-RADS 3-5 lesions that were targeted for biopsy. In total, 108 (87.1%) lesions were found to harbor prostate cancer of any grade. Grade group ≥ 2 prostate cancer was found in 81 (65.3%) of targeted lesions. The detection rates for grade group ≥ 1 and grade group ≥ 2 prostate cancer rose with increasing PI-RADS score. In 65 (68.4%) cases, the patient's highest grade prostate cancer was found within an MRI target. Additionally, 12 of 55 (21.8%) patients who were found to have no or grade group 1 prostate cancer on systematic biopsy were upgraded to grade group ≥ 2 prostate cancer with MRI targeting. Only 1 (1.1%) patient received periprocedural antibiotics and no patient experienced an infectious complication. Self-limited hematuria and hematospermia were commonly reported following the procedure (75.4% and 40.4%, respectively) and only 1 (1.1%) patient developed urinary retention. CONCLUSIONS We demonstrate the safety and feasibility of performing transperineal prostate biopsy using cognitive MRI/biplanar ultrasound fusion guidance. The described technique affords the safety benefits of the transperineal approach as well as obviates the need for a formal fusion platform. Additionally, this method can conveniently be performed under local anesthesia with acceptable tolerability.

Abstract
OBJECTIVE To determine whether use of renal mass biopsy may be associated with a reduction in surgery for patients with small, localized renal cell carcinoma (cT1aN0M0), especially among older patients and patients with greater comorbidity burden. METHODS A total of 106,258 patients with cT1aN0M0 renal cell carcinoma from 2004 to 2015 were analyzed in the National Cancer Data Base. Multivariable logistic regression identified independent associations with nonsurgical management, receipt of biopsy, and pathologic upstaging. Marginal effects were derived by age and comorbidity. A sensitivity analysis was conducted in years identifying patients undergoing active surveillance (2010-2015). RESULTS There was increased use of biopsy (8.0%-15.3%) and nonsurgical management (11.7%-15.6%) over time. Biopsy was significantly associated with use of nonsurgical management (OR 4.80 [95%CI 4.58-5.02], P <.001) as well as active surveillance (OR 1.87 [1.69-2.07], P <.001) in the sensitivity analysis. Individual predicted probability of undergoing nonsurgical management ranged from 3% to 92% (median 31.4% with use of biopsy) and increased with age and comorbidity. Pathologic tumor upstaging (≥pT3a) occurred more frequently for patients receiving biopsy compared to no biopsy (5.8% vs 3.3%, P <.001). After adjustment, biopsy remained a statistically significant predictor of upstaging (OR 1.31 [95%CI 1.24-1.38], P <.001). CONCLUSION Overall, biopsy demonstrated a strong, independent association with reduced use of surgery for cT1aN0M0 kidney cancer, especially with increasing age and comorbidity. The potential association of renal mass biopsy with upstaging warrants caution, but it is uncertain whether it impacts prognosis relative to true perinephric fat invasion.
