Abstract
PURPOSE Nadofaragene firadenovec-vncg is a nonreplicating adenoviral vector-based gene therapy for bacillus Calmette-Guérin (BCG)-unresponsive carcinoma in situ (CIS) with/without high-grade Ta/T1. We report outcomes following 5 years of planned follow-up. MATERIALS AND METHODS This open-label phase 3 trial (NCT02773849) enrolled patients with BCG-unresponsive nonmuscle-invasive bladder cancer in 2 cohorts: CIS ± Ta/T1 (CIS; n = 107) and Ta/T1 without CIS (Ta/T1 cohort; n = 50). Patients received 75 mL (3 × 1011 vp/mL) nadofaragene firadenovec intravesically once every 3 months with cystoscopy and cytology assessments, with continued treatment offered to those remaining high grade recurrence-free (HGRF). RESULTS One hundred fifty-seven patients were enrolled from 33 US sites (n = 151 included in efficacy analyses). Median follow-up was 50.8 months (interquartile range 39.1-60.0), with 27% receiving ≥ 5 instillations and 7.6% receiving treatment for ≥ 57 months. Of patients with CIS 5.8% (95% CI 2.2-12.2) were HGRF at month 57, and 15% (95% CI 6.1-27.8) of patients with high-grade Ta/T1 were HGRF at month 57. Kaplan-Meier-estimated HGRF survival at 57 months was 13% (95% CI 6.9-21.5) and 33% (95% CI 19.5-46.6) in the CIS and Ta/T1 cohorts, respectively. Cystectomy-free survival at month 60 was 49% (95% CI 40.0-57.1): 43% (95% CI 32.2-53.7) in the CIS cohort and 59% (95% CI 43.1-71.4) in the Ta/T1 cohort. Overall survival at 60 months was 80% (71.0, 86.0): 76% (64.6-84.5) and 86% (70.9-93.5) in the CIS and Ta/T1 cohorts, respectively. Only 5 patients (4 with CIS and 1 with Ta/T1) experienced clinical progression to muscle-invasive disease. CONCLUSIONS At 60 months, nadofaragene firadenovec-vncg allowed bladder preservation in nearly half of the patients and proved to be a safe option for BCG-unresponsive nonmuscle-invasive bladder cancer.

Abstract
INTRODUCTION There are notable disparities in health-related quality of life (HRQOL) between gay and bisexual men (GBM) and heterosexual patients with prostate cancer (PCa); however, the role of past military service is unclear. This study examines HRQOL differences in GBM PCa survivors based on reported military service history. METHODS We used data from the 24-month follow-up survey of the Restore-2 study, a clinical trial which evaluated a rehabilitation programme for GBM PCa survivors. PCa HRQOL was assessed using the Expanded Prostate Cancer Index Composite (EPIC-50) and the Functional Assessment of Cancer Treatment-Prostate (FACT-P). Mental health quality of life was assessed using the Brief Symptom Inventory-18 (BSI-18) scale, while sexual functioning was measured using the Sexual Minorities and Prostate Cancer Scale (SMACS). Multivariable linear regression was used to estimate unadjusted and adjusted mean differences in HRQOL between GBM with and without a reported history of military service. RESULTS In this cross-sectional study of 351 GBM PCa survivors, 47 (13.4%) reported a history of US military service. After adjusting for covariates, participants who reported a history of military service (compared with those with no military service) had clinically better scores on the FACT-P physical, social and emotional well-being domains, as well as higher total FACT-General, EPIC urinary bother and hormonal function scores. Additionally, men with a history of military service reported significantly fewer sexual problems, more sexual confidence and less urinary incontinence in sex. CONCLUSION This exploratory study provides the first evidence that GBM PCa survivors with a military background may have clinically better outcomes than those without military service. Potential reasons may include the structured support and healthcare access associated with military service, fostering resilience and well-being. These findings underscore the need for further research to elucidate how military service influences PCa HRQOL.

Abstract
Effective bladder-preserving therapeutic options are needed for patients with bacillus Calmette-Guérin unresponsive non-muscle-invasive bladder cancer. Nadofaragene firadenovec-vncg (Adstiladrin®) was approved by the US Food and Drug Administration as the first gene therapy in urology and the first intravesical gene therapy indicated for the treatment of adult patients with high-risk bacillus Calmette-Guérin-unresponsive non-muscle-invasive bladder cancer with carcinoma in situ with or without papillary tumors. The proposed mechanism of action underlying nadofaragene firadenovec efficacy is likely due to the pleiotropic nature of interferon-α and its direct and indirect antitumor activities. Direct activities include cell death and the mediation of an antiangiogenic effect, and indirect activities are those initiated through immunomodulation of the innate and adaptive immune responses. The sustained expression of interferon-α that results from this treatment modality contributes to a durable response. This review provides insight into potential mechanisms of action underlying nadofaragene firadenovec efficacy.

Abstract
Burgeoning evidence suggests that circulating tumor cells (CTCs) may disseminate into blood vessels at an early stage, seeding metastases in various cancers such as breast and prostate cancer. Simultaneously, the early-stage CTCs that settle in metastatic sites [termed disseminated tumor cells (DTCs)] can enter dormancy, marking a potential source of late recurrence and therapy resistance. Thus, the presence of these early CTCs poses risks to patients but also holds potential benefits for early detection and treatment and opportunities for possibly curative interventions. This review delves into the role of early DTCs in driving latent metastasis within breast and prostate cancer, emphasizing the importance of early CTC detection in these diseases. We further explore the correlation between early CTC detection and poor prognoses, which contribute significantly to increased cancer mortality. Consequently, the detection of CTCs at an early stage emerges as a critical imperative for enhancing clinical diagnostics and allowing for early interventions.

Abstract
PURPOSE The summary presented herein covers recommendations on the early detection of prostate cancer and provides a framework to facilitate clinical decision-making in the implementation of prostate cancer screening, biopsy, and follow-up. This is Part II of a two-part series focusing on initial and repeat biopsies, and biopsy technique. Please refer to Part I for discussion of initial prostate cancer screening recommendations. MATERIALS AND METHODS The systematic review utilized to inform this guideline was conducted by an independent methodological consultant. The systematic review was based on searches in Ovid MEDLINE and Embase and Cochrane Database of Systematic Reviews (January 1, 2000-November 21, 2022). Searches were supplemented by reviewing reference lists of relevant articles. RESULTS The Early Detection of Prostate Cancer Panel developed evidence- and consensus-based guideline statements to provide guidance in prostate cancer screening, initial and repeat biopsies, and biopsy technique. CONCLUSIONS The evaluation of prostate cancer risk should be focused on the detection of clinically significant prostate cancer (Grade Group 2 or higher [GG2+]). The use of laboratory biomarkers, prostate MRI, and biopsy techniques described herein may improve detection and safety when a prostate biopsy is deemed necessary following prostate cancer screening.

Abstract
Gay and bisexual men (GBM) with prostate cancer experience worse sexual and mental health outcomes following prostate cancer treatment than heterosexual men. Emerging evidence suggests that GBM may change their role-in-sex in response to treatment effects. The purpose of this study was to describe the impact of prostate cancer treatment on role-in-sex, to estimate the prevalence of such changes, and to determine the impact on quality of life and mental health. We conducted semi-structured interviews with 30 sexual minority prostate cancer patients. Then, we recruited 401 gay and bisexual prostate cancer patients into a study assessing the effects of rehabilitation. Qualitative data were analyzed using descriptive thematic analysis. Differences in quality of life and mental health outcomes were analyzed using multivariate analyses of variance. Prostate cancer treatment resulted in loss of role-in-sex for many patients. When changes in role-in-sex occurred, the shifts were predominantly from tops to bottoms. Those with a current top role-in-sex had significantly better sexual and mental health outcomes than either versatiles or bottoms. Clinical implications include the need for providers to ask about role-in-sex in order to address disparities in health outcomes by sexual orientation and to provide culturally appropriate care to sexual minority patients.

Abstract
BACKGROUND Anodyspareunia may be an adverse outcome of prostate cancer (PCa) treatment for gay, bisexual, and other men who have sex with men (GBM). AIM The aims of this study were to (1) describe the clinical symptoms of painful receptive anal intercourse (RAI) in GBM following PCa treatment, (2) estimate the prevalence of anodyspareunia, and (3) identify clinical and psychosocial correlates. METHODS This was a secondary analysis of baseline and 24-month follow-up data from the Restore-2 randomized clinical trial of 401 GBM treated for PCa. The analytic sample included only those participants who attempted RAI during or since their PCa treatment (N = 195). OUTCOMES Anodyspareunia was operationalized as moderate to severe pain during RAI for ≥6 months that resulted in mild to severe distress. Additional quality-of-life outcomes included the Expanded Prostate Cancer Index Composite (bowel function and bother subscales), the Brief Symptom Inventory-18, and the Functional Assessment of Cancer Therapy-Prostate. RESULTS Overall 82 (42.1%) participants reported pain during RAI since completing PCa treatment. Of these, 45.1% experienced painful RAI sometimes or frequently, and 63.0% indicated that the pain was persistent. The pain at its worst was moderate to very severe for 79.0%. The experience of pain was at least mildly distressing for 63.5%. Painful RAI worsened for a third (33.4%) of participants after completing PCa treatment. Of the 82 GBM, 15.4% were classified as meeting criteria for anodyspareunia. Antecedents of anodyspareunia included a lifelong history of painful RAI and bowel dysfunction following PCa treatment. Those reporting symptoms of anodyspareunia were more likely to avoid RAI due to pain (adjusted odds ratio, 4.37), which was negatively associated with sexual satisfaction (mean difference, -2.77) and self-esteem (mean difference, -3.33). The model explained 37.2% of the variance in overall quality of life. CLINICAL IMPLICATIONS Culturally responsive PCa care should include the assessment of anodyspareunia among GBM and explore treatment options. STRENGTHS AND LIMITATIONS This is the largest study to date focused on anodyspareunia among GBM treated for PCa. Anodyspareunia was assessed with multiple items characterizing the intensity, duration, and distress related to painful RAI. The external validity of the findings is limited by the nonprobability sample. Furthermore, the cause-and-effect relationships between the reported associations cannot be established by the research design. CONCLUSIONS Anodyspareunia should be considered a sexual dysfunction in GBM and investigated as an adverse outcome of PCa treatment.

Abstract
559 Background: BLASST-1 is multi-center phase II trial evaluating neoadjuvant nivolumab (N) with gemcitabine-cisplatin (GC) for patients (pts) with MIBC undergoing radical cystectomy (RC) (NCT03294304). 41 pts with MIBC (cT2-T4a, N≤1, M0) were enrolled between Feb 2018 and June 2019; (cT2N0 90%, cT3N0 7%, cT4N1 3%). Pts received C (70mg/m2) IV on D1, G (1000mg/m2) on D1, D8 and N (360 mg) IV on D8 every 21 days for 4 cycles followed by RC within 8 wks. Primary endpoint was pathologic down staging (PaR; ≤pT1N0). Safety, Relapse-free survival (RFS), Progression-free survival (PFS) and biomarker analyses were secondary endpoints. PaR rate was 65.8%, pCR (≤pT is N0) rate was 49% and there were no safety concerns or delays to RC. At a median follow-up of 15.8 mos, 12-month RFS rate was 85.4% and PFS including death from any cause was 83%. We now report correlation of PaR with tumor mutation patterns of responders (R) and non-responders (NR) using Whole Genome Sequencing (WGS). Methods: DNA was extracted from pre-treatment tumor samples and sequenced to an average depth of 150X and DNA extracted from matched normal tissue (peripheral blood) to a mean depth of 50X. We analyzed 32 Tumor/Normal pairs and 6 Tumor only Whole Genome Samples; 26 pts were classified as (R) and 12 as (NR). Raw sequencing data samples were aligned to hg38 genome build using Burrows-Wheeler Aligner (BWA) followed by duplicate-read removal and base-quality score recalibration using the Genome Analysis Toolkit (GATK). Somatic SNV and INDELS were called by combination of 5 callers (Mutect2, Strelka, VarScan, Platypus and SomaticSniper) for Tumor/Normal pairs and Mutect2 for Tumor only samples following the guidelines of GDC DNA-Seq analysis pipeline. Set of genes known to be significantly mutated in MIBC and shown to impact response/resistance to chemotherapy/immunotherapy respectively were selected. Samples were grouped by response status. Results: Median tumor mutational burden (TMB) for the dataset closely matches with TCGA results. Genes ERCC2, ARID1A, DSP, HMCN1, ERBB2, ERBB3, STAG2, BRCA2 present in (R) only, whereas VHL, ERCC4, PALB2, CDKN2A and CSMD3 present in (NR) only. We also grouped genes based on their biological processes by known Oncogenic Signaling Pathways and the 3 most common pathways are Genome Integrity, RTK Signaling and Transcription Factor with the latter two primarily enriched in (R). We identified a SNP rs2853669 in 5 (NR) and 14 (R). Conclusions: The genomic analysis suggests ERCC2, ARID1A, DSP, HMCN1, ERBB2, ERBB3,STAG2, BRCA2 correlated with PaR and VHL, ERCC4, PALB2, CDKN2A and CSMD3 correlated with lack of response. In addition, RTK Signaling and Transcription Factor were primarily enriched in (R). This genomic correlation of response/resistance to neoadjuvant chemo-immunotherapy in MIBC can help guide future biomarker-driven studies. Clinical trial information: NCT03294304 .

Abstract
This study is the first to quantify experiences of discrimination in treatment undertaken by sexual and gender minority prostate cancer patients. Participants were 192 gay and bisexual and one transgender prostate cancer patients living in the US recruited from North America's largest online cancer support group. In this online survey, discrimination in treatment was measured using the Everyday Discrimination Scale (EDS), adapted for medical settings. Almost half (46%) endorsed at least one item, including 43% that the provider did not listen, 25% that they were talked down to, 20% that they received poorer care than other patients, 19% that the provider acted as superior, and 10% that the provider appeared afraid of them. While most (26.3%) rated the discrimination as "rare" or "sometimes" (EDS=1-3), 20% reported it as more common (EDS≥4). Most attributed the discrimination to their sexual orientation, or to providers being arrogant or too pushed for time. Discrimination was significantly associated with poorer urinary, bowel, and hormonal (but not sexual) EPIC function and bother scores, and with poorer mental health (SF-12). Those who had systemic/combined treatment (versus either radiation only or surgery only) were more likely to report discrimination. This study provides the first evidence that discrimination in prostate cancer treatment, including micro-aggressions, appear a common experience for gay and bisexual patients, and may result in poorer health outcomes.

Abstract
Prostate cancer treatments disrupt receptive anal intercourse (RAI) for gay and bisexual men (GBM). Sexual dysfunction following prostate cancer treatment may include severe pain in the anorectum during RAI (i.e., anodyspareunia). The purpose of this study was to explore the impact of prostate cancer and its treatments on RAI among GBM. Data were from a cross-sectional online survey of 100 GBM prostate cancer survivors who reported pleasurable RAI prior to treatment. Approximately 47% of the sample reported recent RAI, which was more common among GBM in long-term relationships. RAI was also associated with engagement in other sexual behaviors (e.g., oral and insertive anal sex). Anodyspareunia was reported by 23% of the men who had attempted recent RAI. Anodyspareunia was negatively associated with mental health, performing oral sex on a partner, and bowel function. The overwhelming majority received no information from their healthcare providers about loss of RAI function prior to prostate cancer treatment. Culturally responsive cancer survivorship care may need to address the loss of RAI function for GBM prostate cancer survivors.

Abstract
PURPOSE To systematically review the literature to investigate racial disparities among bladder cancer clinical trial enrollees. METHODS A systematic review was conducted using Ovid, MEDLINE® to identify clinical trials between 1970 and 2020. Articles were reviewed and were included if they assessed race in their outcomes reporting among bladder cancer patients enrolled in clinical trials. The review was conducted in accordance with the PRISMA statement. RESULTS We identified 544 clinical trials meeting our initial search criteria, with only 24 (4.4%) studies reporting racial demographic data. Enrollees were largely Caucasian (81-98%), with a strikingly small proportion of enrolled patients consisting of African-Americans (2-8%) and Hispanics (2-5%). Only one of the studies reported results on the efficacy and safety/tolerability of the tested treatment separately for racial groups and performed analyses stratified by race. CONCLUSION Race is poorly studied in bladder cancer clinical trials. Trial cohorts may not reflect multicultural populations. The potential association between race and efficacy, safety or tolerability of the tested interventions is unknown. Given the up to twofold increase in bladder cancer-specific death among African-Americans, further research is needed to address the impact of race in clinical trials, while encompassing socioeconomic factors and disease risk factor exposures.

Abstract
OBJECTIVE In this study, we investigated if outness is more a situational or a consistent characteristic in gay, bisexual, and other men who have sex with men (GBM) treated for prostate cancer and how the disclosure of sexual orientation impacts provider discussions of sexual side effects. METHODS Data came from Restore, an online cross-sectional survey of 193 GBM prostate cancer survivors living in North America and were analyzed using various statistical models. RESULTS Disclosure of sexual orientation and of living with prostate cancer were not significantly correlated. Participants who were out regarding sexual orientation were more likely to report that their surgeons and urologists discussed the sexual side effects of treatment. CONCLUSION Outness appears to be a situational phenomenon. GBM prostate cancer survivors who were out regarding sexual orientation received more discussion surrounding sexual side effects of prostate cancer treatment from their providers. PRACTICE IMPLICATIONS It is important for healthcare providers to inquire about patient's sexual orientation to provide holistic care to these patients to address health disparities within this group.

Abstract
Background Equitable cancer survivorship care for gay and bisexual male (GBM) prostate cancer survivors should be responsive to their sexual health needs. Rates of sexually transmitted infections (STIs) are higher among GBM compared to heterosexual men across the lifespan. In addition, evidence suggests that GBM will use a variety of strategies to cope with sexual dysfunction that may increase risk for STIs. The purpose of this study was to determine the prevalence of STIs following prostate cancer treatment among GBM and identify risk factors. Methods In 2019, 401 GBM previously treated for prostate cancer were recruited into the Restore-2 Study. They completed a baseline online questionnaire with items assessing STIs diagnosed since being treated for prostate cancer. Any STI diagnoses was regressed on demographic, clinical, and relationship related variables using binary logistic regression. Results Forty-five participants (11.4%) were diagnosed with an STI during or following their prostate cancer treatment. The mostly commonly diagnosed STI was syphilis (4.3%), followed by gonorrhoea (2.8%), and chlamydia (2.5%). Four participants were infected with HIV following their prostate cancer treatment. Independent risk factors for STI diagnosis included time since prostate cancer diagnosis (aOR = 1.18; 95% CI: 1.10-1.26), nonmonogamous sexual relationship (aOR = 11.23; 95% CI: 2.11-59.73), better sexual function (aOR = 1.02; 95% CI: 1.01-1.04), penile injection treatment (aOR = 3.28; 95% CI: 1.48-7.29), and multiple sex partners (aOR = 5.57; 95% CI: 1.64-18.96). Conclusions GBM prostate cancer survivors are at risk for STIs. Culturally responsive STI prevention should be incorporated into cancer survivorship plans, particularly as men are treated for and regain sexual function over time.

Abstract
Introduction Prostate cancer treatment has established effects on the health-related quality of life (HRQOL) of patients. While racial/ethnic differences in HRQOL have been explored in heterosexual patients, this is the first study to examine racial/ethnic differences in a cohort of sexual minority prostate cancer survivors. Methods We used data from the Restore-1 study, an online cross-sectional survey of sexual and gender minority (SGM) prostate cancer survivors in North America, to explore the association between race/ethnicity and HRQOL. General mental and physical HRQOL was assessed using the Short-Form Health Survey version 2 (SF-12). The frequency and distress of prostate cancer specific symptoms was assessed using the Expanded Prostate Cancer Composite (EPIC) scale. Multivariable linear regression was used to estimate mean differences in HRQOL between sexual minority men of color and their white, non-Hispanic counterparts after adjustment for pertinent demographic and medical characteristics. Results Among 190 participants, 23 (12%) self-identified as non-white and/or Hispanic. In unadjusted analysis, sexual minority men of color compared to their white counterparts reported worse HRQOL scores in the EPIC hormonal summary (73.8 vs. 81.8) and hormonal function (70.9 vs 80.5) domains. Clinically important differences between men of color and their white counterparts were seen in the EPIC bowel function (mean difference (MD): -4.5, 95% CI: -9.9, 0.8), hormonal summary (MD: -8.0, 95% CI: -15.6, -0.4), hormonal function (MD: -9.6, 95% CI: -17.6, -1.6), and hormonal bother (MD: -6.7, 95% CI: -14.4, 1.1) domains. After adjustment for covariates, clinically important differences persisted between men of color and white, non-Hispanic men on the hormonal summary (74.4 vs. 81.7), hormonal function (71.3 vs. 80.3), and hormonal bother (77.0 vs. 82.7) domains. Conclusions This exploratory study provides the first evidence that sexual minority men of color may have worse HRQOL outcomes compared to white, non-Hispanic sexual minority men following prostate cancer treatment.

Abstract
BACKGROUND/AIMS Sexual minorities are small and under-researched populations that are at disproportionate risk for cancer and poor cancer outcomes. Described as a "hidden population," the principal research challenge has been to develop effective methods to identify and recruit such cancer patients into cancer studies. Online recruitment strategies, as well as targeted clinic recruitment using patient-entered sexual orientation and gender identity data from electronic medical records have potential to transform recruitment, but studies testing the effects of how to recruit using these have not been published. METHODS In 2019, we conducted a naturalistic, three-arm, stratified prospective study to compare three recruitment strategies: (a) clinic based recruitment of prostate cancer patients from gay health and urology clinics; (b) directly from the gay community; and (c) online recruitment (through cancer support, sex/dating, and social sites). For each strategy, we estimated time, workload, and direct costs involved. To study how recruitment strategy may affect sampling, we tested for retention rates, demographic and outcome differences across sites. Using these methods, we successfully recruited 401 gay and bisexual prostate cancer patients into a randomized, controlled, 24-month trial testing an online sexual and urinary rehabilitation curriculum tailored for this population. RESULTS There were seven key results. First, it is possible to recruit substantial numbers of sexual minority men into prostate cancer studies provided online recruitment methods are used. Second, we observed big differences in dropout during study onboarding by recruitment source. Third, within online recruitment, the online sex/dating application (app) was the most successful and efficient, followed by the cancer support site, and then the social networking site. Fourth, while clinics were the cheapest source of recruitment, they were time intensive and low in yield. Fifth, the cancer support site and sex/dating app recruits differed by several characteristics, with the former being more rehabilitation-focused while the latter were younger and more sexually active. Sixth, we found almost no differences in outcomes across the three online recruitment sites. Seventh, because retention in online studies has been a concern, we confirm very low attrition at 3- and 6 months into the trial. CONCLUSION For sexual minority cancer research, more research on how to use sexual orientation and gender identity electronic medical record data for clinic-based recruitment is needed. For other small or hard-to-reach populations, researchers should compare and publish online versus offline recruitment strategies.

Abstract
BACKGROUND Existing measures of sexual functioning in prostate cancer survivors focus primarily on erectile function and do not adequately measure the experiences of sexual minority men. AIM To develop and psychometrically evaluate a new scale to measure sexual functioning among sexual minority men with prostate cancer. METHODS Sexual minority prostate cancer patients (n = 401) completed an online battery of urinary and sexual functioning tests in 2019, including a new 37-item instrument about their sexual functioning post-treatment for prostate cancer. OUTCOMES We used confirmatory factor analysis to determine the construct validity of a new scale including five subscales: a four-factor model for all participants (n = 401) evaluated Sexual Satisfaction, Sexual Confidence, Frequency of Sexual Problems, and Urinary Incontinence in Sex. A single-factor model completed only by participants who had attempted or desired receptive anal sex (n = 255) was evaluated in the fifth subscale: Problematic Receptive Anal Sex. To evaluate criterion validity, we calculated the intercorrelations between each Sexual Minorities and Prostate Cancer Scale (SMACS) subscale and four related scales: the Expanded Prostate Cancer Index Composite-50 (EPIC), the Functional Assessment of Cancer Therapy-Prostate, the Brief Symptom Inventory-18, and the International Consultation on incontinence questionnaire. Cronbach's alphas were calculated to measure internal consistency (ie, reliability). RESULTS Cronbach's alpha values ranged from 0.64 to 0.89. Loadings (0.479-0.926) and model fit indices were strong (Root Mean Square Error of Approximation: 0.085, Standardized root mean squared residual: 0.063, comparative fit index: 0.927, Tucker-Lewis Index: 0.907). For criterion validity, Sexual Satisfaction, Sexual Confidence, and Frequency of Sexual Problems were moderately correlated with EPIC function and bother scores (r = 0.50-0.72) and Urinary incontinence in sex correlated moderately with EPIC Urinary Function and International Consultation on incontinence questionnaire scores (0.45-0.56). CLINICAL IMPLICATIONS The SMACS can be used by clinicians and researchers to comprehensively measure sexual functioning in sexual minority men, in conjunction with existing scales. STRENGTHS AND LIMITATIONS This new scale is validated in a large, geographically diverse cohort of sexual minority cancer survivors and fills an important gap in existing measures of sexual functioning. Limitations include a lack of a validation sample. CONCLUSION The SMACS is a valid and reliable new scale that measures sexual minority men's experience of urinary incontinence in sex, problematic receptive anal sex, and sexual distress.

Abstract
A recent phase 3 trial of intravesical nadofaragene firadenovec reported a promising complete response rate for patients with bacillus Calmette-Guérin-unresponsive non-muscle-invasive bladder cancer. This study examined the ability of antiadenovirus antibody levels to predict the durability of therapeutic response to nadofaragene firadenovec. A standardized and validated quantitative assay was used to prospectively assess baseline and post-treatment serum antibody levels among 91 patients from the phase 3 trial, of whom 47 (52%) were high-grade recurrence free at 12 mo (responders). While baseline titers did not predict treatment response, 3-mo titer >800 was associated with a higher likelihood of durable response (p = 0.026). Peak post-treatment titers >800 were noted in 42 (89%) responders versus 26 (59%) nonresponders (p = 0.001; assay sensitivity, 89%; negative predictive value, 78%). Moreover, 22 (47%) responders compared with eight (18%) nonresponders had a combination of peak post-treatment titers >800 and peak antibody fold change >8 (p = 0.004; assay specificity, 82%; positive predictive value, 73%). A majority of responders continued to have post-treatment antibody titers >800 after the first 6 mo of therapy. In conclusion, serum antiadenovirus antibody quantification may serve as a novel predictive marker for nadofaragene firadenovec response durability. Future studies will focus on large-scale validation and clinical utility of the assay. PATIENT SUMMARY: This study reports on a planned secondary analysis of a phase 3 multicenter clinical trial that established the benefit of nadofaragene firadenovec, a novel intravesical gene therapeutic, for the treatment of patients with bacillus Calmette-Guérin (BCG)-unresponsive high-risk non-muscle-invasive bladder cancer. Prospective assessment of serum anti-human adenovirus type-5 antibody levels of patients in this trial indicated that a combination of post-treatment titers and fold change from baseline can predict treatment efficacy. While this merits additional validation, our findings suggest that serum antiadenovirus antibody levels can serve as an important predictive marker for the durability of therapeutic response to nadofaragene firadenovec.

Abstract
528 Background: The BLASST-1 study is multi-center phase II trial evaluating the combination of nivolumab (N) with gemcitabine-cisplatin (GC) as a neoadjuvant therapy for patients (pts) with MIBC undergoing radical cystectomy (RC). The primary endpoint was pathologic down staging (PaR; ≤pT1N0). Safety, Relapse-free survival (RFS), Progression-free survival (PFS) and biomarker analyses were secondary endpoints. We previously reported a PaR rate of 65.8% and pCR rate of 49%. There were no safety concerns or delays to surgery. (ASCO GU 2020) Here, we correlate PaR with biomarkers (Tumor mutational burden (TMB), PD-L1 and molecular subtypes) and provide updated clinical follow-up (FU) data. Methods: Forty-one pts with MIBC (cT2-T4a, N≤1, M0) and candidates for RC were enrolled between Feb 2018 and June 2019; (cT2N0 90%, cT3N0 7%, cT4N1 3%). Pts received C (70mg/m2) IV on D1, G (1000mg/m2) on D1, D8 and N (360 mg) IV on D8 every 21 days for 4 cycles followed by RC within 8 weeks. For RNA-based analysis, GeneChip Human Exon 1.0 ST Array (Affymetrix) was used; baseline tumors from 37 patients passed quality control and had available transcriptome data. A cohort (n=223) of patients treated with NAC+RC was used as a comparator for molecular subtyping analysis. DNA was extracted from baseline pre-treatment tumor samples and sequenced to an average depth of 150X and the DNA extracted from matched normal tissue (peripheral blood) to a mean depth of 50X. PD-L1 expression was assessed using IHC 28-8 antibody on baseline tumors. Results: At a median FU of 15.8 months,12-month RFS rate was 85.4% and PFS including death from any cause was 83%. There were no long-term safety concerns. Molecular subtyping found patients with a basal-type tumor (Basal or Claudin-low) had a more favorable overall PaR in 13/18 = 73% with PaR in 9/13 in basal (69%) and 4/5 in claudin-low (80%) compared to overall PaR of 58% for the luminal-type tumors (Luminal or Infiltrated luminal) with a breakdown of PaR in 5/8 (63%) in luminal and 6/11 (54%) in infiltrated luminal. In contrast, in the comparator NAC cohort, the PaR rates were similar for basal-type and luminal-type tumors, with 44% and 48% respectively. There was no correlation of PaR with TMB or PD-L1 expression from bassline pre-treatment tumors. Biomarker analyses from residual tumors in RC tissues are ongoing. Conclusions: The combination of N+GC was safe and efficacious in MIBC with encouraging outcomes of pathologic down staging and relapse-free survival at a median FU of 15.8 months. Molecular subtyping results suggest basal-type tumors may respond more favorably to this chemo-immunotherapy treatment regimen. Clinical trial information: NCT03294304.

Abstract
PURPOSE The NIH has identified sexual and gender minority persons as a health disparity population but little is known about cancer outcomes in these populations. The purpose of this study was to identify disparities in sexual minority prostate cancer patient-reported outcomes, to examine within group differences, and to test for alternative explanations for identified differences. MATERIALS AND METHODS In 2019, we recruited 401 gay and bisexual prostate cancer patients into the Restore-2 study, a randomized controlled trial of rehabilitation program tailored for sexual minority men. RESULTS Compared to the normative (heterosexual) EPIC sample, participants had significantly worse urinary, bowel and hormonal function, better sexual function, and no difference on bother scores. They also had worse depression and overall mental health, and worse physical, social/family, functional, prostate specific and overall well-being quality of life outcomes. Across measures, no differences by age, gay versus bisexual orientation, race/ethnicity, and relationship status were observed. Those who had hormonal treatment had worse sexual and hormonal function than those who had radiation or surgery only. Those with a longer time since treatment had better urinary function. Differences remained when participants were matched to normative samples on cancer stage and time since treatment. CONCLUSIONS This, the largest study of sexual minority prostate cancer patients to date, confirms health disparities in prostate cancer quality of life outcomes. Findings appear reliable and robust. To improve the clinical care of prostate cancer, it will be important to address the health disparities experienced by sexual minority prostate cancer patients.

Abstract
IMPORTANCE No data exist on time to recovery of patient-reported and performance-related measures of functional independence after radical cystectomy (open or robotic). OBJECTIVE To determine recovery of functional independence after radical cystectomy and whether robot-assisted radical cystectomy (RARC) is associated with any advantage over open procedures. DESIGN, SETTING, AND PARTICIPANTS Data for this secondary analysis from the RAZOR (Randomized Open vs Robotic Cystectomy) trial were used. RAZOR was a phase 3 multicenter noninferiority trial across 15 academic medical centers in the US from July 1, 2011, to November 18, 2014, with a median follow-up of 2 years. Participants included the per-protocol population (n = 302). Data were analyzed from February 1, 2017, to May 1, 2021. INTERVENTIONS Robot-assisted radical cystectomy or open radical cystectomy (ORC). MAIN OUTCOMES AND MEASURES Patient-reported (activities of daily living [ADL] and independent ADL [iADL]) and performance-related (hand grip strength [HGS] and Timed Up & Go walking test [TUGWT]) measures of independence were assessed. Patterns of postoperative recovery for the entire cohort and comparisons between RARC and ORC were performed. Exploratory analyses to assess measures of independence across diversion type and to determine whether baseline impairments were associated with 90-day complications or 1-year mortality were performed. FINDINGS Of the 302 patients included in the analysis (254 men [84.1%]; mean [SD] age at consent, 68.0 [9.7] years), 150 underwent RARC and 152 underwent ORC. Baseline characteristics were similar in both groups. For the entire cohort, ADL, iADL, and TUGWT recovered to baseline by 3 postoperative months, whereas HGS recovered by 6 months. There was no difference between RARC and ORC for ADL, iADL, TUGWT, or HGS scores at any time. Activities of daily living recovered 1 month after RARC (mean estimated score, 7.7 [95% CI, 7.3-8.0]) vs 3 months after ORC (mean estimated score, 7.5 [95% CI, 7.2-7.8]). Hand grip strength recovered by 3 months after RARC (mean estimated HGS, 29.0 [95% CI, 26.3-31.7] kg) vs 6 months after ORC (mean estimated HGS, 31.2 [95% CI, 28.8-34.2] kg). In the RARC group, 32 of 90 patients (35.6%) showed a recovery in HGS at 3 months vs 32 of 88 (36.4%) in the ORC group (P = .91), indicating a rejection of the primary study hypothesis for HGS. Independent ADL and TUGWT recovered in 3 months for both approaches. Hand grip strength showed earlier recovery in patients undergoing continent urinary diversion (mean HGS at 3 months, 31.3 [95% CI, 27.7-34.8] vs 33.9 [95% CI, 30.5-37.3] at baseline; P = .09) than noncontinent urinary diversion (mean HGS at 6 months, 27.4 [95% CI, 24.9-30.0] vs 29.5 [95% CI, 27.2-31.9] kg at baseline; P = .02), with no differences in other parameters. Baseline impairments in any parameter were not associated with 90-day complications or 1-year mortality. CONCLUSIONS AND RELEVANCE The results of this secondary analysis suggest that patients require 3 to 6 months to recover baseline levels after radical cystectomy irrespective of surgical approach. These data will be invaluable in patient counseling and preparation. Hand grip strength and ADL tended to recover to baseline earlier after RARC; however, there was no difference in the percentage of patients recovering when compared with ORC. Further study is needed to assess the clinical significance of these findings. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT01157676.

Abstract
INTRODUCTION Despite the effectiveness of blue light cystoscopy (BLC) in the management of bladder cancer, the adoption of BLC since its approval has been limited. We evaluated the perceived clinical utility of BLC and assessed factors associated with higher perceived utility of BLC. METHODS This study used a prospective multi-institutional registry of patients with known or suspected noninvasive bladder cancer. Following BLC, urologists assessed their perceived clinical utility of BLC on a 4-point Likert scale. The primary outcome was the perceived clinical utility of BLC as assessed by participating urologists. RESULTS A total of 1,702 rigid cystoscopies performed between 2014 and 2019 were evaluated. Of all lesions biopsied 2,285 were identified with both white light and blue light (60.6%), followed by 867 with blue light only (23.0%) and 423 with white light only (11.2%). Among all post-cystoscopy surveys, urologists perceived BLC to be of some utility (38.1%, 648), moderate assistance (25.4%, 432), essential (19%, 324) and no real utility (17.5%, 298). More urologists perceived BLC to be essential in 2019 (28.3%, 30/106) compared to in 2014 (11.5%, 9/78; p=0.006). On multivariable analysis higher perceived utility was associated with more lesions seen only with blue light (LR 4.88, CI 2.27-8.78), malignant pathology on biopsy (LR 3.31, CI 2.10-5.23), and total number of lesions seen with blue light (LR 1.36, CI 1.19-1.55). CONCLUSIONS The perceived clinical utility of BLC has been increasing over time, particularly among high-volume urologists. Urologists who identify more lesions with BLC than white light cystoscopy perceive BLC to be most clinically useful.

Abstract
OBJECTIVES To determine the potential impact of the presence of secondary variant histology on the gene expression profiles of muscle-invasive bladder cancer (MIBC) tumors. METHODS For six tumors, revised samples were collected from urothelial and secondary variant components (cohort A). The commercial cohort (cohort B) consisted of the anonymized gene expression profiles of 173 patients with MIBC. Samples were obtained from the clinical use of the Decipher Bladder test that were available as part of the Decipher GRID prospective registry (NCT02609269). Secondary variant presence in cohort B was abstracted from institutional pathology reports. For the commercial cohort, only the urothelial carcinoma component was profiled. RESULTS Molecular subtyping of both urothelial and variant components found micropapillary and nested cases were classified as a luminal subtype. Conversely, the sarcomatoid and small cell cases were classified as basal/squamous or neuroendocrine-like, respectively. For cohort B, 50 (29%) of 173 cases had reported secondary variant histology. Cases with squamous variant had basal profiles, small cell cases expressed neuronal markers, and micropapillary cases were classified as luminal. Sarcomatoid tumors had robust epithelial-mesenchymal transition marker expression. CONCLUSIONS Our data suggest that in MIBC with secondary variant, the urothelial component can demonstrate an expression profile that closely resembles the variant component.

Abstract
Introduction Studies have demonstrated worse health related quality of life (HRQOL) outcomes in gay and bisexual men (GBM) following prostate cancer treatment compared to heterosexual men potentially due to differences in comorbidity burden. Aim To establish the prevalence of comorbidities and their association with HRQOL metrics in GBM following prostate cancer treatment. Methods We evaluated HRQOL and prevalence of comorbidities in 193 GBM from the United States and Canada in a cross-sectional, online survey: the Masked for Review. HRQOL was measured with the Expanded Prostate Cancer Index Composite (EPIC) and the 12-Item Short Form Health Survey (SF-12). Main Outcome Measures Our outcomes included comorbidity prevalence, mean differences for HRQOL scores by comorbidity status, and mean differences for HRQOL by comorbidity count. Results GBM were found to have a higher prevalence of blood vessel disease and mental health disorders but lower prevalence of obesity and type 2 diabetes when compared to published data in general prostate cancer populations. Statistically significant reductions in HRQOL metrics were associated with mental health diagnoses, diabetes, and obesity. Increased number of comorbidities was also associated with reductions in HRQOL metrics in nearly all categories. Conclusion These results suggest that the worse QOL outcomes in GBM following prostate cancer treatment may be due to differences in comorbidity burden. This study is the first to evaluate the relationship between comorbidities and HRQOL outcomes in GBM. Limitations of this study include a small sample size and cross-sectional study design. If confirmed in larger, longitudinal, clinically confirmed studies, these findings indicate a need to intervene on and consider comorbidities in GBM diagnosed with prostate cancer.

Abstract
Objective To review the recent milestones in MRI and PET based imaging and evaluate their evolving role in the setting of elevated PSA as well as localized prostate cancer. Background The importance of multiparametric MRI (mpMRI) and PET based imaging for the diagnosis and staging of prostate cancer cannot be understated. Accurate staging has become another significant milestone with the use of PET scans, particularly with prostate specific radiotracers like 68-Gallium Prostate Specific Membrane Antigen (68Ga-PSMA). Integrated PET/MRI systems are commercially available and can be modulated to evaluate the unique needs of localized as well as recurrent prostate cancer. Methods A literature search was performed using PubMed and Google Scholar using the MeSH compliant and other keywords that included prostate cancer, PSA, mpMRI, PET CT, PET/MRI. Conclusions mpMRI has now established itself as the gold-standard of local prostate imaging and has been incorporated into international guidelines as part of the diagnostic work-up of prostate cancer. PSMA PET/CT has shown superiority over conventional imaging even in staging of localized prostate cancer based on recent randomized control data. Imaging parameters from PET/MRI have been shown to be associated with malignancy, Gleason score and tumour volume. As mpMRI and PSMA PET/CT become more ubiquitous and established; we can anticipate more high-quality data, cost optimization and increasing availability of PET/MRI to be ready for primetime in localized prostate cancer.

Abstract
This study investigates the experience of communicating sexual orientation by gay, bisexual and men who have sex with men (GBM) to physicians involved in their prostate cancer care. Methodology consisted of qualitative analysis conducted on 30 in-depth interviews of GBM recruited from a national online cancer support site. Results revealed four key strategies around sexual disclosure. These ranged from explicitly outing themselves to selective or non-disclosure. Disclosures had unpredictable multiple outcomes ranging from increased trust in the patient-physician relationship to seeking alternate treatment. We concluded competent care is achieved when physicians know their patient's sexual orientation, and are trained in them.

Abstract
Purpose: We evaluated the acceptability and feasibility of collecting sexual orientation and gender identity (SOGI) data in oncology and urology clinical settings. Methods: We surveyed 101 urology and 104 oncology clinic patients with a standardized sexual orientation question with six response options, "lesbian, gay, or homosexual;" "straight or heterosexual;" "bisexual;" "something else;" "do not know;" and "choose not to disclose." Next, we added the sexual orientation question and an expanded gender identity question to the electronic medical record (EMR) and analyzed data on the first 450 urology and 103 oncology patients. Acceptability and feasibility were assessed based on responses to the survey and patient intake forms. Results: In the acceptability survey, only 3% of urology and 4% of oncology patients selected "choose not to disclose." Over 90% of patients in both clinics assessed the sexual orientation question as understandable and easy to answer. In all, 79% of urology and 73% of oncology patients stated they would answer it in their EMR, but only 56% of urology and 54% of oncology patients described the information as important. Sexual minority patients were as likely as heterosexual patients to state they would answer the question. Only 5% of patients selected "choose not to disclose" for sexual orientation, and <1% for the expanded gender identity question. Conclusion: Adding SOGI questions to the EMR appears to be acceptable and feasible and the sexual orientation question was understandable to a large majority of urology and oncology patients.

Abstract
PURPOSE In general, participation rates in cancer clinical trials are very low. However, participation rates are especially low among the socially disadvantaged and racial and ethnic minority groups. These groups have been historically under-represented in cancer clinical trials. Although many patient-related barriers have been studied, institutional factors that are essential for building clinical research infrastructure around the clinical trial enterprise in academic medical centers have been underexplored. MATERIALS AND METHODS We assessed perspectives of cancer center professional stakeholders on the institutional factors that can potentially influence racial and ethnic minority recruitment for cancer clinical trials. Ninety-one qualitative interviews were conducted at five US cancer centers among four stakeholder groups: cancer center leaders, principal investigators, referring clinicians, and research staff. Qualitative analyses examined response data focused on institutional factors related to minority recruitment for cancer clinical trials. RESULTS Four prominent themes emerged regarding institutional barriers among clinical and research professionals. (1) There are no existing programs currently being used to recruit or retain minorities to clinical trials. (2) Institutional efforts are needed to increase trial participation and are not specific to potential minority participants. (3) Access to cancer clinical trials and navigation within an Academic Medical Center need to be simplified to better facilitate recruitment of minority patients. (4) Community outreach by cancer centers will increase clinical research awareness in the community. CONCLUSION Our research highlights the need to address institutional barriers to improve the success of minority recruitment. To increase participation among minority populations, medical centers must address mutable institutional barriers such as setting specific minority recruitment goals for cancer clinical trials, ensuring that cancer clinical trials are accessible, especially to minority patients, and supporting sustained community outreach programs to increase clinical research awareness.

Abstract
In 2016, the NIH designated sexual and gender minorities (SGM) a health disparity population. The next year, the American Society of Clinical Oncology highlighted the need to improve the suboptimal cancer and survivorship care received by SGM populations. There are currently no evidence-based training programs in culturally competent care of prostate cancer patients who are gay, bisexual and/or transgender. In this selective review, we summarize findings from the largest quantitative studies focused on sexual minority prostate cancer survivors and from 65 interviews with NIH staff, clinicians, and cancer clinics in 11 US cities. The report is divided into three parts and uses a question and answer format to address 21 questions relevant to clinicians providing care to SGM prostate cancer patients. First, we identify population-specific issues that are culturally relevant in the care of SGM patients with prostate cancer. While a body of research has emerged on sexual minority prostate cancer patients, the literature on gender minorities is limited to single case reports and inadequate to inform practice. This review covers definitions, population size, cultural and historical context, sexual behavior, population invisibility, sexual orientation and gender identity (SOGI) in the electronic medical record, disparities and evidence of discrimination in treatment provision. The second part focuses on promoting evidence-informed, patient-centered care. This includes current practices in assessing sexual orientation, management of disclosure of sexual orientation, how to address common problems sexual minority men experience post-treatment, common questions sexual minority patients have, management of urinary incontinence, HIV and STI risk during and post-treatment, and sub-groups of sexual minority patients with worse outcomes. It then identifies how male partners differ in prostate cancer support, current research on rehabilitation for sexual minority men, issues in advanced prostate cancer, and things to avoid with minority patients. Finally, we examine the cultural divide between provider and patient, advocating for cultural humility when working with minority patients. Training programs and continuing education can help providers both to become more aware of their own cultural assumptions, informed about health disparities, and able to provide quality care, and to make clinics more welcoming to SGM patients.

Abstract
BACKGROUND Standard treatment for high-risk non-muscle-invasive bladder cancer is transurethral resection of bladder tumour followed by intravesical BCG immunotherapy. However, despite high initial responses rates, up to 50% of patients have recurrence or become BCG-unresponsive. PD-1 pathway activation is implicated in BCG resistance. In the KEYNOTE-057 study, we evaluated pembrolizumab, a PD-1 inhibitor, in BCG-unresponsive non-muscle-invasive bladder cancer. METHODS We did this open-label, single-arm, multicentre, phase 2 study in 54 sites (hospitals and cancer centres) in 14 countries. In cohort A of the trial, adults aged 18 years or older with histologically confirmed BCG-unresponsive carcinoma in situ of the bladder, with or without papillary tumours, with an Eastern Cooperative Oncology Group performance status of 0-2, and who were ineligible for or declined radical cystectomy were enrolled. All enrolled patients were assigned to receive pembrolizumab 200 mg intravenously every 3 weeks for up to 24 months or until centrally confirmed disease persistence, recurrence, or progression; unacceptable toxic effects; or withdrawal of consent. The primary endpoint was clinical complete response rate (absence of high-risk non-muscle-invasive bladder cancer or progressive disease), assessed by cystoscopy and urine cytology approximately 3 months after the first dose of study drug. Patient follow-ups were done every 3 months for the first 2 years and every 6 months thereafter for up to 5 years. Efficacy was assessed in all patients who received at least one dose of the study drug and met BCG-unresponsive criteria. Safety was assessed in all patients who received at least one dose of the study drug. This trial is registered with ClinicalTrials.gov number, NCT02625961, and is ongoing. FINDINGS Between Dec 9, 2015, and April 1, 2018, we screened 334 patients for inclusion. 186 patients did not meet inclusion criteria, and 47 patients were assigned to cohort B (patients with BCG-unresponsive high grade Ta or any grade T1 papillary disease without carcinoma in situ; results will be reported separately). 101 eligible patients were enrolled and assigned to receive pembrolizumab. All 101 patients received at least one dose of the study drug and were included in the safety analysis. Five patients had disease that did not meet the US Food and Drug Administration definition of BCG-unresponsive non-muscle-invasive bladder cancer and were therefore not included in the efficacy analysis (n=96). Median follow-up was 36·4 months (IQR 32·0-40·7). 39 (41%; 95% CI 30·7-51·1) of 96 patients with BCG-unresponsive carcinoma in situ of the bladder with or without papillary tumours had a complete response at 3 months. Grade 3 or 4 treatment-related adverse events occurred in 13 (13%) patients; the most common were arthralgia (in two [2%] patients) and hyponatraemia (in three [3%] patients). Serious treatment-related adverse events occurred in eight (8%) patients. There were no deaths that were considered treatment related. INTERPRETATION Pembrolizumab monotherapy was tolerable and showed promising antitumour activity in patients with BCG-unresponsive non-muscle-invasive bladder cancer who declined or were ineligible for radical cystectomy and should be considered a a clinically active non-surgical treatment option in this difficult-to-treat population.

Abstract
Introduction: Urine leak following radical cystectomy is a known complication. Among the various methods to diagnose this, assessment of drain fluid creatinine is a relatively easy procedure. We aimed to ascertain the validity of the drain fluid creatinine-to-serum creatinine ratio (DCSCR) as an initial indicator of urinary leak in patients undergoing radical cystectomy. Methods: We retrospectively identified consecutive patients with documentation of drain fluid creatinine in the postoperative period following cystectomy and urinary diversion at our institution between January 2009 and December 2018. All continent diversions and any patient with a DCSCR >1.5:1 underwent contrast study postoperatively. A diagnosis of urine leak was made following confirmatory imaging. Receiver operative characteristic curves were created, and Youden's index was used to determine the strength and clinical utility of DCSCR as a diagnostic test. Results: Two hundred forty-four of the 340 patients included in the study underwent cystectomy with conduit and 81 underwent neobladder creation. Sixteen out of 340 (4.7%) patients had radiologically confirmed urinary leak. DCSCR was elevated in all ureteric anastomotic leaks and in 1 out of the 7 neobladder-urethral anastomotic (NUA) leaks. The sensitivity and specificity of DCSCR to predict all urinary leaks were 68.8% and 80.9% at 1.12 (area under the curve [AUC] = 0.838), whereas at a value of 1.18 (AUC = 0.876) and with the exclusion of NUA leaks, the sensitivity was 77.8% and specificity was 87.6%. Conclusions: DCSCR is a good preliminary test for identifying patients who need prompt confirmatory testing for localizing urinary leaks. A drain creatinine level just 18% higher than the serum creatinine level can signify a urine leak. This is different from general assumptions of a higher DCSCR.

Abstract
451 Background: Pembrolizumab (pembro) was approved in January 2020 for treatment of HR NMIBC based on interim results from 96 patients (pts) in the open-label, single-arm, multicenter, phase II KEYNOTE-057 (NCT02625961) study. Here we present updated efficacy and safety results with extended minimum follow-up of 26.3 mo from KEYNOTE-057 cohort A. Methods: Pts aged ≥18 years with histologically confirmed Bacillus Calmette-Guérin (BCG)–unresponsive HR carcinoma in situ (CIS), with or without papillary tumors, who were ineligible for or declined radical cystectomy (RC) received pembro 200 mg Q3W for up to 24 mo or until disease persistence, recurrence, progression, or unacceptable toxicity. Primary end point: complete response rate (CRR). Key secondary end points: duration of response (DOR) and safety. Results: Overall, 101 pts received pembro and 96 were included in the efficacy analysis (5 patients did not meet BCG-unresponsive criteria). Median age was 73 years (range, 44-92), and pts received a median of 12.0 (range, 7.0-45.0) BCG instillations. Median time from enrollment to data cutoff date of May 25, 2020, was 36.4 mo (range, 26.3-48.5). Of 96 pts, CRR was 40.6% (95% CI, 30.7-51.1) at first evaluable disease assessment, and median DOR was 16.2 mo (range, 0.0+ to 36.2). Of 39 responders, 13 (33.3%) remained in CR ≥18 mo and 9 (23.1%) remained in CR ≥24 mo as of the data cutoff date. No pt progressed to MIBC while on study treatment based on protocol-specified disease assessments. CRR was generally consistent with the primary analysis across protocol-prespecified subgroups, including PD-L1 expression status. Forty pts (41.7%) underwent RC after discontinuation of pembro; 35 pts (88%) had no pathologic upstaging to MIBC, 2 (5%) had no available pathology data, and 3 (8%) had evidence of MIBC (all nonresponders); 1 pt had pT2N0 disease at 60 days after the last pembro dose, 1 pt had pT2N1 disease (involvement of a single perivesical lymph node) at 86 days after the last pembro dose, and 1 pt had pT3N1 disease at 457 days after the last pembro dose. For other subsequent treatments, 30 of 96 pts (31.3%) received additional intravesical therapy (eg, BCG), 27 of 96 (28.1%) underwent local procedures (eg, TURBT), and 10 of 96 (10.4%) received systemic therapy. In 101 pts, treatment-related AEs (TRAEs) occurred in 67 pts (66.3%); most frequent were diarrhea, fatigue, and pruritus (10.9% each). Grade 3/4 TRAEs occurred in 13 pts (12.9%). Twenty-two pts (21.8%) experienced immune-related AEs; 3.0% were grade 3-4. Seven pts (6.9%) discontinued due to TRAEs. There were no grade 5 TRAEs. Conclusions: With extended follow-up, pembro continued to show durable and clinically meaningful activity in pts who had HR BCG-unresponsive CIS with or without papillary tumors and who were ineligible for or declined RC. No new safety risks were identified. Clinical trial information: NCT02625961.

Abstract
BACKGROUND BCG is the most effective therapy for high-risk non-muscle-invasive bladder cancer. Nadofaragene firadenovec (also known as rAd-IFNa/Syn3) is a replication-deficient recombinant adenovirus that delivers human interferon alfa-2b cDNA into the bladder epithelium, and a novel intravesical therapy for BCG-unresponsive non-muscle-invasive bladder cancer. We aimed to evaluate its efficacy in patients with BCG-unresponsive non-muscle-invasive bladder cancer. METHODS In this phase 3, multicentre, open-label, repeat-dose study done in 33 centres (hospitals and clinics) in the USA, we recruited patients aged 18 years or older, with BCG-unresponsive non-muscle-invasive bladder cancer and an Eastern Cooperative Oncology Group status of 2 or less. Patients were excluded if they had upper urinary tract disease, urothelial carcinoma within the prostatic urethra, lymphovascular invasion, micropapillary disease, or hydronephrosis. Eligible patients received a single intravesical 75 mL dose of nadofaragene firadenovec (3 × 1011 viral particles per mL). Repeat dosing at months 3, 6, and 9 was done in the absence of high-grade recurrence. The primary endpoint was complete response at any time in patients with carcinoma in situ (with or without a high-grade Ta or T1 tumour). The null hypothesis specified a complete response rate of less than 27% in this cohort. Efficacy analyses were done on the per-protocol population, to include only patients strictly meeting the BCG-unresponsive definition. Safety analyses were done in all patients who received at least one dose of treatment. The study is ongoing, with a planned 4-year treatment and monitoring phase. This study is registered with ClinicalTrials.gov, NCT02773849. FINDINGS Between Sept 19, 2016, and May 24, 2019, 198 patients were assessed for eligibility. 41 patients were excluded, and 157 were enrolled and received at least one dose of the study drug. Six patients did not meet the definition of BCG-unresponsive non-muscle-invasive bladder cancer and were therefore excluded from efficacy analyses; the remaining 151 patients were included in the per-protocol efficacy analyses. 55 (53·4%) of 103 patients with carcinoma in situ (with or without a high-grade Ta or T1 tumour) had a complete response within 3 months of the first dose and this response was maintained in 25 (45·5%) of 55 patients at 12 months. Micturition urgency was the most common grade 3-4 study drug-related adverse event (two [1%] of 157 patients, both grade 3), and there were no treatment-related deaths. INTERPRETATION Intravesical nadofaragene firadenovec was efficacious, with a favourable benefit:risk ratio, in patients with BCG-unresponsive non-muscle-invasive bladder cancer. This represents a novel treatment option in a therapeutically challenging disease state. FUNDING FKD Therapies Oy.

Abstract
INTRODUCTION OR OBJECTIVE Men with favorable-risk prostate cancer (PCa) on active surveillance may benefit from intervention strategies to slow or prevent disease progression and the need for definitive treatment. Pomegranate and its extracts have shown antiproliferative and proapoptotic effects in cell lines and animal models, but its effect on human prostate cancer as a target tissue remain unclear. Objectives of this trial include pomegranate's ability to alter serum and prostate tissue biomarkers and the ability of an active surveillance cohort to adhere to a chemoprevention trial for 1 year. METHODS Men with organ-confined, favorable-risk PCa on AS were randomly assigned to receive pomegranate fruit extract (PFE) 1000 mg (n = 15) or placebo (n = 15) once daily for twelve months. Prostate biopsies were performed at study entry and upon completion of the 1-year intervention. Plasma and urinary biomarkers were analyzed utilizing immunoassays and HPLC. Tissue proteins were assessed by immunohistochemistry (IHC) and measured by automated quantitation. RESULTS PFE was well-tolerated with no significant toxicities. One patient withdrew before study initiation and 29 completed the 1-year intervention. No differences in plasma insulin-like growth factor-1 (IGF-1) levels, prostate-specific antigen doubling time, or biopsy kinetics were observed. Metabolites including urolithin A and urolithin A-gluc were detected more frequently in the PFE arm in both urine and plasma (p < .001 and p = .006, respectively). IHC analyses revealed reductions from baseline in 8-OHdG (a DNA damage marker) (p = .01) and androgen receptor expression (p = .04) in prostate tumor associated with PFE treatment. CONCLUSION PFE administration for 12-month was well-tolerated and the protocol followed in an active surveillance population. Analyses suggest that PFE contains bioactive compounds capable of altering biomarkers involving oxidative stress and androgen signaling in prostate tumor and normal-appearing adjacent tissue. No alterations in the IGF axis were noted. This finding of study adherence and target activity provides a rationale for the further investigation of PFE in the active surveillance population.

Abstract
BACKGROUND Systemic androgen deprivation therapy (ADT), also referred to as hormone therapy,ÃÂ has long been the primary treatment for metastatic prostate cancer. Additional agents have been reserved for the castrate-resistant disease stage when ADT start becoming less effective. Abiraterone is an agent with an established role in that disease stage, which has only recently been evaluated in the hormone-sensitive setting. OBJECTIVES To assess the effects of early abiraterone acetate, in combination with systemic ADT, for newly diagnosed metastatic hormone-sensitive prostate cancer. SEARCH METHODS We searched CENTRAL, MEDLINE, Embase, six other databases, two trials registries, grey literature, and conference proceedings, up to 15 May 2020. We applied no restrictions on publication language or status. SELECTION CRITERIA We included randomized trials, in which men diagnosed with hormone-sensitive prostate cancer were administered abiraterone acetate and prednisolone with ADT or ADTÃÂ alone. DATA COLLECTION AND ANALYSIS Two review authors independently classified studies and abstracted data from the included studies. We performed statistical analyses using a random-effects model. We rated the quality of evidence according to the GRADE approach. MAIN RESULTS The search identified two randomized controlled trials (RCT), with 2201 men, who were assigned to receive either abiraterone acetate 1000 mg once daily and low dose prednisone (5mg) in addition to ADT, or ADT alone. In the LATITUDE trial, the median age and range of men in the intervention group was 68 (38 to 89) years, and 67 (33 to 92) years in the control group. Nearly all of the men in thisÃÂ study (97.6%) had prostate cancer with a Gleason score of at least 8 (ISUP grade group 4). Primary outcomes The addition of abiraterone acetate to ADT reduces the probability of death from any cause compared to ADT alone (hazard ratio [HR] 0.64, 95% confidence interval [CI] 0.56 to 0.73; 2 RCTs, 2201 men; high certainty of evidence); this corresponds to 163 fewer deaths per 1000 men with hormone-sensitive metastaticÃÂ prostate cancerÃÂ (210 fewer to 115 fewer) at five years. Abiraterone acetate in addition to ADT probably results in little to no differenceÃÂ in quality of life compared to ADT alone, measured with the Functional Assessment of Cancer Therapy-prostate total score (FACT-P; range 0 to 156; higher values indicates better quality of life),ÃÂ at 12 months (mean difference [MD] 2.90 points, 95% CI 0.11 to 5.60; 1 RCT, 838 men; moderate certainty of evidence). Secondary outcomes Abiraterone plus ADT increases the risk of grades III to V adverse events compared to ADT alone (risk ratio [RR] 1.34, 95% CI 1.22 to 1.47; 1 RCT, 1199 men; high certainty of evidence); this corresponds to 162 more grade III to VÃÂ events per 1000 men with hormone-sensitive metastaticÃÂ prostate cancerÃÂ (105 more to 224 more) at a median follow-up of 30ÃÂ months. Abiraterone acetate in addition to ADT probably reduces the probability of death due to prostate cancer compared to ADT alone (HR 0.58, 95% CI 0.50 to 0.68; 2 RCTs, 2201 men; moderate certainty of evidence). This corresponds to 120 fewer death from prostate cancer per 1000 men with hormone-sensitive metastaticÃÂ prostate cancerÃÂ (95% CI 145 fewer to 90 fewer) afterÃÂ a median follow-up of 30 months. The addition of abiraterone acetate to ADT probably decreases the probability of disease progression compared to ADT alone (HR 0.35, 95%CI 0.26 to 0.49; 2 RCTs, 2097 men; moderate certainty of evidence). This corresponds to 369 fewer incidences of disease progression per 1000 men with hormone-sensitive metastaticÃÂ prostate cancerÃÂ (456 fewer to 256 fewer)ÃÂ after a median follow-up of 30 months. The addition of abiraterone acetate to ADT probably increases the risk of discontinuing treatment due to adverse events compared to ADT alone (RR 1.50, 95% CI 1.17 to 1.92; 1 RCT, 1199 men; moderate certainty of evidence). This corresponds to 51 more men (95% CI 17 more to 93 more) discontinuing treatment because of adverse events per 1000 men treated with abiraterone acetate and ADT compared to ADT alone afterÃÂ a median follow-up of 30 months. AUTHORS' CONCLUSIONS The addition of abiraterone acetate to androgen deprivation therapy improves overall survival but probably not quality of life. ItÃÂ probably also extends disease-specific survival, and delays disease progression compared to androgen deprivation therapy alone. However, the risk of grades III to V adverse events is increased, and probably, so is the risk of discontinuing treatment due to adverse events.

Abstract
OBJECTIVE To compare the accuracy of 68 gallium prostate-specific membrane antigen positron emission tomography/computed tomography (68 Ga-PSMA PET/CT) with multiparametric MRI (mpMRI) in detecting and localising primary prostate cancer when compared with radical prostatectomy (RP) specimen pathology. PATIENTS AND METHODS Retrospective review of men who underwent 68 Ga-PSMA PET/CT and mpMRI for primary prostate cancer before RP across four centres between 2015 and 2018. Patients undergoing imaging for recurrent disease or before non-surgical treatment were excluded. We defined pathological index tumour as the lesion with highest International Society of Urological Pathology Grade Group (GG) on RP specimen pathology. Our primary outcomes were rates of accurate detection and localisation of RP specimen pathology index tumour using 68 Ga-PSMA PET/CT or mpMRI. We defined tumour detection as imaging lesion corresponding with RP specimen tumour on any imaging plane, and localisation as imaging lesion matching RP specimen index tumour in all sagittal, axial, and coronal planes. Secondary outcomes included localisation of clinically significant and transition zone (TZ) index tumours. We defined clinically significant disease as GG 3-5. We used descriptive statistics and the Mann-Whitney U-test to define and compare demographic and pathological characteristics between detected, missed and localised tumours using either imaging modality. We used the McNemar test to compare detection and localisation rates using 68 Ga-PSMA PET/CT and mpMRI. RESULTS In all, 205 men were included in our analysis, including 133 with clinically significant disease. There was no significant difference between 68 Ga-PSMA PET/CT and mpMRI in the detection of any tumour (94% vs 95%, P > 0.9). There was also no significant difference between localisation of all index tumours (91% vs 89%, P = 0.47), clinically significant index tumours (96% vs 91%, P = 0.15) or TZ tumours (85% vs 80%, P > 0.9) using 68 Ga-PSMA PET/CT and mpMRI. Limitations include retrospective study design and non-central review of imaging and pathology. CONCLUSION We found no significant difference in the detection or localisation of primary prostate cancer between 68 Ga-PSMA PET/CT and mpMRI. Further prospective studies are required to evaluate a combined PET/MRI model in minimising tumours missed by either modality.

Abstract
S100A4 oncoprotein plays a critical role during prostate cancer progression and induces immunosuppression in host tissues. We hypothesized that S100A4-regulated oncogenic activity in immunosuppressed prostate tumors promotes growth of neoplastic cells, which are likely to become aggressive. In the current study, we investigated whether biopsy-S100A4 gene alteration independently predicts the outcome of disease in patients and circulatory-S100A4 is druggable target for treating immunosuppressive prostate cancer. Aided by DECIPHER-genomic test, we show biopsy-S100A4 overexpression as predictive of (i) poor ADT response and (ii) high risk of mortality in 228 radical prostatectomy-treated patients. Furthermore, analysis of tumor genome data of more than 1,000 patients with prostate cancer (PRAD/SU2C/FHCRC studies) validated the association of S100A4-alteration to poor survival and metastasis. We show that increased serum-S100A4 levels are associated to the prostate cancer progression in patients. The prerequisite for metastasis is the escape of tumor cells via vascular system. We show that extracellular-S100A4 protein as a growth factor induces vascular transmigration of prostate cancer cells and bone demineralization thus forms an ideal target for therapies for treating prostate cancer. By employing surface plasmon resonance and isothermal titration calorimetry, we show that mab6B12 antibody interacts with and neutralizes S100A4 protein. When tested for therapeutic efficacy, the mab6B12 therapy reduced the (i) osteoblastic demineralization of bone-derived MSCs, (ii) S100A4-target (NFκB/MMP9/VEGF) levels in prostate cancer cells, and (iii) tumor growth in a TRAMPC2 syngeneic mouse model. The immuno-profile analysis showed that mAb6B12-therapy (i) shifted Th1/Th2 balance (increased Stat4+/T-bet+ and decreased GATA2+/CD68+/CD45+/CD206+ cells); (ii) modulated cytokine levels in CD4+ T cells; and (iii) decreased levels of IL5/6/12/13, sTNFR1, and serum-RANTES. We suggest that S100A4-antibody therapy has clinical applicability in treating immunosuppressive prostate cancer in patients.

Abstract
BACKGROUND There is a need to develop novel therapies which could be beneficial to patients with prostate cancer (CaP) including those who are predisposed to poor outcome, such as African-Americans. This study investigates the role of ROBO1-pathway in predicting outcome and race-based disparity in patients with CaP. METHODS AND RESULTS Aided by RNA sequencing-based DECIPHER-testing and immunohistochemical (IHC) analysis of tumors we show that ROBO1 is lost during the progressive stages of CaP, a prevalent feature in African-Americans. We show that the loss of ROBO1 predicts high-risk of recurrence, metastasis and poor outcome of androgen-deprivation therapy in radical prostatectomy-treated patients. These data identified an aggressive ROBO1deficient /DOCK1+ve sub-class of CaP. Combined genetic and IHC data showed that ROBO1 loss is accompanied by DOCK1/Rac1 elevation in grade-III/IV primary-tumors and Mets. We observed that the hypermethylation of ROBO1-promoter contributes to loss of expression that is highly prevalent in African-Americans. Because of limitations in restoring ROBO1 function, we asked if targeting the DOCK1 could be an ideal strategy to inhibit progression or treat ROBO1deficient metastatic-CaP. We tested the pharmacological efficacy of CPYPP, a selective inhibitor of DOCK1 under in vitro and in vivo conditions. Using ROBO1-ve and ROBO1+ve CaP models, we determined the median effective concentration of CPYPP for growth. DOCK1-inhibitor treatment significantly decreased the (a) Rac1-GTP/β-catenin activity, (b) transmigration of ROBO1deficient cells across endothelial lining, and (c) metastatic spread of ROBO1deficient cells through the vasculature of transgenicfl Zebrafish model. CONCLUSION We suggest that ROBO1 status forms as predictive biomarker of outcome in high-risk populations such as African-Americans and DOCK1-targeting therapy has a clinical potential for treating metastatic-CaP.

Abstract
Inhibiting the disease progression in KRAS-driven cancers after diagnosis has been a difficult task for clinicians to manage due to the lack of effective intervention/preventive therapies. KRAS-driven cancers depend on sustained KRAS signaling. Although developing inhibitors of KRAS signaling has proven difficult in the past, the quest for identifying newer agents has not stopped. Based on studies showing terpenoids as modulators of KRAS-regulated downstream molecular pathways, we asked if this chemical family has an affinity of inhibiting KRAS protein activity. Using crystal structure as a bait in silico, we identified 20 terpenoids for their KRAS protein-binding affinity. We next carried out biological validation of in silico data by employing in situ, in vitro, patient-derived explant ex vivo, and KPC transgenic mouse models. In this report, we provide a comprehensive analysis of a lup-20(29)-en-3b-ol (lupeol) as a KRAS inhibitor. Using nucleotide exchange, isothermal titration calorimetry, differential scanning fluorimetry, and immunoprecipitation assays, we show that lupeol has the potential to reduce the guanosine diphosphate/guanosine triphosphate exchange of KRAS protein including mutant KRASG12V . Lupeol treatment inhibited the KRAS activation in KRAS-activated cell models (NIH-panel, colorectal, lung, and pancreatic intraepithelial neoplasia) and patient tumor explants ex vivo. Lupeol reduced the three-dimensional growth of KRAS-activated cells. The pharmacokinetic analysis showed the bioavailability of lupeol after consumption via oral and intraperitoneal routes in animals. Tested under prevention settings, the lupeol consumption inhibited the development of pancreatic intraepithelial neoplasia in LSL-KRASG12D/Pdx-cre mice (pancreatic ductal adenocarcinoma progression model). These data suggest that the selected members of the triterpene family (such as lupeol) could be exploited as clinical agents for preventing the disease progression in KRAS-driven cancers which however warrants further investigation.

Abstract
Prostate cancer is the second most common cancer in gay, bisexual, and other men who have sex with men (GBM). Few studies have assessed the effects of treatment on GBM's sexual behavior. For an online survey, 193 gay and bisexual men with prostate cancer were recruited from the North American's largest online cancer support group. Sexual functioning was measured using the Expanded Prostate Cancer Index Composite (EPIC) and a tailored Gay Sexual Functioning Inventory (GSFI). GBM have worse EPIC urinary and hormonal function and worse hormonal bother, but better sexual function and bother scores than published norms. In the GSFI, two-thirds of participants described their sexual functioning, post-treatment, as fair to poor. Only 22% reported erections sufficient for insertive anal sex. For receptive anal sex, one-third met criteria for anodyspareunia. Over half reported urination problems during sex or at orgasm. Erectile difficulties were common, severe, and a reason cited for not using condoms. Three men HIV seroconverted post-prostate cancer treatment. Differences in function and bother scores were observed by type of treatment, age, race/ethnicity, sexual orientation, but not relationship status. Sexual functioning significantly predicted long-term mental and physical health. GBM scored significantly worse on mental health and better on physical health than published norms. Sexual recovery after prostate cancer treatment is problematic for most GBM. Research to develop more effective sexual recovery, tailored to the needs of GBM treated for prostate cancer, is needed. Six implications for clinicians treating GBM with prostate cancer are identified.

Abstract
TPS5090 Background: Immune checkpoint inhibitors, including NIVO (anti–PD-1), have demonstrated favorable tolerability and efficacy profiles, ushering in a new treatment (tx) paradigm for advanced bladder cancer (advBC). However, an unmet need exists for new effective tx options in earlier stages of disease, specifically for patients (pts) with BCG-unresponsive, high-risk NMIBC. Increased IDO and PD-L1 expression in NMIBC tumors (Inman, et al. Cancer 2007; Hudolin, et al. Anticancer Res 2017), support the combination of anti–PD-1 and IDO1 inhibition in NMIBC. Linrodostat mesylate, a selective, potent, once-daily IDO1 inhibitor, has demonstrated clinical activity in combination with NIVO in pts with immunotherapy-naive advBC who received ≥ 1 prior line of therapy (objective response rate, 37%; Tabernero, et al. J Clin Oncol 2018;36(suppl) [abstr 4512]). Furthermore, high levels of PD-L1 expression have been reported in patients not responding to BCG tx. These findings provide a rationale for investigation of NIVO ± linrodostat ± intravesical BCG therapy in BCG-unresponsive high-risk NMIBC. Here we describe a phase 2, randomized, open-label study assessing the safety and efficacy of NIVO ± linrodostat ± intravesical BCG in pts with BCG-unresponsive, high-risk NMIBC (NCT03519256). Methods: Pts aged ≥ 18 years with BCG-unresponsive (per February 2018 FDA guidance), high-risk NMIBC, defined as carcinoma-in-situ (CIS) with or without papillary component, any T1, or Ta high-grade lesions, will be enrolled. Pts must have urothelial carcinoma as the predominant histological component ( > 50%). Key exclusion criteria include locally advanced or metastatic BC, upper urinary tract disease within 2 years, prostatic urethral disease within 1 year, and prior immunotherapy. Using a novel adaptive-type design, pts will be randomized to 1 of 4 tx arms with NIVO ± linrodostat ± BCG. Primary endpoints include proportion of pts with CIS with complete response (CR) and duration of CR in pts with CIS. Secondary endpoints are progression-free survival and safety. This global study in 14 countries is underway, with a target enrollment of 436 pts. Clinical trial information: NCT03519256 .

Abstract
5041 Background: Pembro was recently approved for the treatment of HR NMIBC based on results from the phase 2 KEYNOTE-057 (NCT02625961) study. Herein we present safety, efficacy, and posttreatment outcomes with > 2 y follow-up from KEYNOTE-057 cohort A. Methods: Patients with histologically confirmed HR BCG-unresponsive carcinoma in situ (CIS) with or without papillary tumors who received adequate BCG therapy and were ineligible for or opted out of radical cystectomy (RC) received pembro 200 mg Q3W for up to 2 y or until disease recurrence, progression, or unacceptable toxicity. The primary end point was complete response rate (CRR). Key secondary end points were duration of response (DOR) and safety. Results: Overall, 102 patients were initially enrolled, and 96 were included in the efficacy analysis. Median time from enrollment to data cut off was 28.4 months (range, 18.2-40.5). CRR was 40.6% (95% CI, 30.7-51.1), and median DOR was 16.2 months (range, 0+ to 30.4+). Among 39 patients with CR, 18 (46.2%) had a DOR ≥12 months. No patient’s disease progressed to muscle-invasive or metastatic bladder cancer while on study treatment. Median PFS and OS were not reached. At 12 months, PFS was 82.7% and OS was 97.9%. A total of 36 patients (37.5%) underwent RC after discontinuation from study treatment, which included 9 of 22 patients (40.9%) who had recurrence after initial CR and 27 of 57 (47.4%) nonresponders. Of the 36 who underwent RC, 33 (91.6%) had no pathological upstaging to MIBC and 3 (8.3%) had at least pT2 disease at time of RC. For subsequent treatments other than RC, 27 of 96 (28.1%) patients received additional intravesical therapy (eg, BCG, gemcitabine, or mitomycin), 21 of 96 (21.9%) underwent local procedures (eg, TURBT), and 3 of 96 (3.1%) received systemic therapy (eg, pembro). In 102 patients treated with pembro, treatment-related AEs (TRAEs) occurred in 67 (65.7%) patients; most frequently reported TRAEs were fatigue, pruritus, and diarrhea (10.8% each). Grade 3/4 TRAEs occurred in 13 patients (12.7%), and 21 patients (20.6%) experienced immune-mediated AEs. There were no grade 5 TRAEs. Conclusions: After > 2 y of follow-up, durable and clinically meaningful activity of pembro was observed in patients who had HR BCG-unresponsive CIS with or without papillary tumors and who were ineligible for or opted out of RC. Pembro did not seem to limit the opportunity for subsequent therapies, including RC. The safety profile was consistent with what is reported in the literature.

Abstract
PURPOSE The American Urological Association (AUA) introduced evidence-based guidelines for the management of nonmuscle invasive bladder cancer (NMIBC) in 2016. We sought to assess the implementation of these guidelines among members of the Society of Urologic Oncology (SUO) with an aim to identifying addressable gaps. METHODS AND MATERIALS An SUO approved survey was distributed to 747 members from December 28, 2018 to February 2, 2019. This 14-question online survey (Qualtrics, SAP SE, Germany) consisted of 38 individual items addressing specific statements from the AUA NMIBC guidelines within 3 broad categories - initial diagnosis, surveillance, and imaging/biomarkers. Adherence to guidelines was assessed by dichotomizing responses to each item that was related to recommended action statement within the guidelines. Statistical analysis was applied using Pearson's chi-squared test, where a P-value of <0.05 was considered statistically significant. RESULTS A total of 121 (16.2%) members completed the survey. Members reported a mean of 71% guidelines adherence; adherence was higher for the intermediate- and high-risk subgroups (82% and 76%, respectively) compared to low-risk (58%). Specifically, adherence to guideline recommended cystoscopic surveillance intervals for low-risk disease differed based on clinical experience (60.9% [<10 years] vs. 36.8% [≥10 years], P = 0.01) and type of fellowship training (55.2% [urologic oncology] vs. 28.0% [none/other], P = 0.02). CONCLUSION Adherence to guidelines across risk-categories was higher for intermediate- and high-risk patients. Decreased adherence observed for low-risk patients resulted in higher than recommended use of cytology, imaging, and surveillance cystoscopy. These results identify addressable gaps and provide impetus for targeted interventions to support high-value care, especially for low-risk patients.

Abstract
In two studies, gay, bisexual, and other men who have sex with men prostate cancer survivors report lower Gleason scores than heterosexual prostate cancer survivors, leading some to speculate that men who have sex with men may have more intensive screening than other men. In the largest study of men who have sex with men prostate cancer survivors to date, 23 of 193 (11.9%) men who have sex with men prostate cancer survivors reported low Gleason scores (2-5). We contacted 14 of them, a 61 percent response rate. At second interview, most men clarified that they reported only a partial score rather than the sum score. We conclude the average lower score is not a result of differences in screening but likely measurement error. A revised Gleason item question is provided to overcome this research artifact.
