Diversity, Equity, and Inclusion: Advancing Curricular Development and Recruitment.

PURPOSE OF REVIEW: Currently, the increasing diversity of our society is poorly reflected in the urology workforce. In this review, we sought to address this disparity by highlighting key components involved in forming an academic urology department and training program that is focused on diversity, equity, and inclusion (DEI) as well as recruitment and retention of underrepresented in medicine (URiM) trainees and faculty. RECENT FINDINGS: We identified obstacles and provided approaches to enhance the ability of a department in creating a DEI-based curriculum and recruitment strategy with a key focus on understanding and addressing unconscious biases and microaggressions in the workplace. Substantive changes in the level of diversity within the urologic community can be made through the organization of a structured approach to increasing DEI. It starts with a commitment from each department to form achievable goals surrounding early mentorship of URiM students and trainees, an inclusive curriculum that is rooted in DEI, and targeted benchmarks for recruitment and retention of diverse staff.

Determinants of neoadjuvant chemotherapy for urothelial muscle-invasive bladder cancer: Does location matter?

INTRODUCTION: Bladder cancer care has been increasingly concentrated in high-volume metropolitan medical centres (ie, "regionalisation" of care). We aimed to assess the potential role of geographic factors, including facility region and distance to treatment centre, as determinants of neoadjuvant chemotherapy (NAC) delivery in patients with non-metastatic urothelial muscle-invasive bladder cancer (MIBC) using nationally representative data from the United States. METHODS: We queried the National Cancer Database to identify patients with cT2-cT4a, N0M0 urothelial MIBC who underwent radical cystectomy (RC) from 2006 to 2015. Patients who received radiation therapy, single-agent chemotherapy, adjuvant chemotherapy or systemic therapies other than multi-agent chemotherapy were excluded. Multivariate logistic regression analysis was performed to identify independent predictors of receiving NAC. RESULTS: A total of 5986 patients met the criteria for inclusion, of whom 1788 (29.9%) received NAC and 4108 received RC alone. Younger age, increased Charlson-Deyo score, increased cT stage, increased annual income, increased distance from cancer treatment centre, treatment at an Academic Research Program or Integrated Network Cancer Program and a later year of diagnosis were independently predictive of NAC receipt. Older age, Medicare insurance and treatment in the East South Central or West South Central regions were independently associated with decreased odds of NAC receipt. CONCLUSIONS: Distance to treatment centre and United States geographic region were found to affect the likelihood of NAC receipt independently of other established predictors of success in this quality-of-care metric. Access to transportation and related resources merits consideration as additional pertinent social determinants of health in bladder cancer care.

Assessing the role of race in pathological upstaging of renal cell carcinoma: Results from the National Cancer Database.

PURPOSE: Pathologic upstaging in renal cell carcinoma (RCC) is common and confers a significant risk of poor surgical and survival outcomes. Preoperative predictors of upstaging are of great clinical relevance but empirical evidence specific to racial minorities remains scarce. METHODS: National Cancer Database (NCDB) analysis of T3a-specific upstaging among White, African-American, Hispanic and Asian Pacific Islander (API) patients with AJCC cT1N0M0 RCC who underwent partial or radical nephrectomy between 2010 and 2015. Independent preoperative predictors of tumour upstaging were identified using multivariate logistic regression analyses. RESULTS: A total of 81 002 patients met the criteria for inclusion (5.6% T3a-specific upstaging). Increased age, increased Charlson-Deyo comorbidity index, clinical stages cT1b and unspecified cT1, and increased Fuhrman nuclear grade were identified as independent risk factors for upstaging. Independent protective factors for upstaging were younger age, female sex, African-American race and papillary, chromophobe, and unspecified RCC histologic subtypes. Significant risk factors and protective factors within individual racial subgroups were highly consistent with those observed in the overall study sample. All independent factors identified on race-specific subgroup analyses were significant in the same direction relative to the overall study sample. Variables found to be non-significant in the overall study sample remained non-significant across all racial subgroup analyses. CONCLUSION: The present study of nationally representative data found no clinically significant differences in upstaging risk across individual racial subgroups relative to the overall study sample. Preoperative factors that can be used to predict pT3a-specific tumour upstaging in CT1N0M0 RCC likely persist across different racial groups.

Changes observed in prostate biopsy practices in an inner city hospital with a high risk patient population following the 2012 uspstf psa screening recommendations.

INTRODUCTION: We compared characteristics of patients undergoing prostate biopsy in a high-risk inner city population before and after the 2012 USPSTF recommendation against PSA based prostate cancer screening to determine its effect on prostate biopsy practices. MATERIALS AND METHODS: This was a retrospective study including patients who received biopsies after an abnormal PSA measurement from October 2008-December 2015. Patients with previously diagnosed prostate cancer were excluded. Chi-square tests of independence, two sample t-tests, Mann-Whitney U tests, and Fisher's exact tests were performed. RESULTS: There were 202 and 208 patients in the pre-USPSTF and post-USPSTF recommendation cohorts, respectively. The post-USPSTF cohort had higher median PSA (7.8 versus 7.1ng/mL, p=0.05), greater proportion of patients who were black (96.6% versus 90.5%, p=0.01), and greater percentage of biopsy cores positive for disease (58% versus 29.5%, p<0.001). Multivariable analysis supported that the increase in PSA was independent of the increase in the proportion of patients who were black. The proportion of patients who were classified as D'Amico intermediate and high-risk disease increased in the post-USPSTF cohort and approached statistical significance (70.1% versus 58.8%, p=0.12). CONCLUSIONS: Our study suggests that the USPSTF recommendations may have led to na increase in pre-biopsy PSA as well as greater volume of disease. Also, a greater proportion of patients were being classified with intermediate or high risk disease. While the clinical significance of these findings is unknown, what the data suggests is somewhat troubling. Future research should further examine these changes in a larger cohort as well as resultant long-term outcomes.

Retroperitoneal hemorrhage after ureteroscopy without laser lithotripsy: an extreme example of an underreported event?

Retroperitoneal hemorrhage and an associated hematoma are uncommon but potentially serious complications following ureteroscopy with laser lithotripsy. However, no reports of serious bleeding complications have been published regarding ureteroscopy without laser lithotripsy in the management of stone disease. We report of such a case here and then review the current literature in order to discuss the incidence, risk factors, and management of such events.

Preliminary evaluation of urinary soluble Met as a biomarker for urothelial carcinoma of the bladder.

BACKGROUND: Among genitourinary malignancies, bladder cancer (BCa) ranks second in both prevalence and cause of death. Biomarkers of BCa for diagnosis, prognosis and disease surveillance could potentially help prevent progression, improve survival rates and reduce health care costs. Among several oncogenic signaling pathways implicated in BCa progression is that of hepatocyte growth factor (HGF) and its cell surface receptor, Met, now targeted by 25 experimental anti-cancer agents in human clinical trials. The involvement of this pathway in several cancers is likely to preclude the use of urinary soluble Met (sMet), which has been correlated with malignancy, for initial BCa screening. However, its potential utility as an aid to disease surveillance and to identify patients likely to benefit from HGF/Met-targeted therapies provide the rationale for this preliminary retrospective study comparing sMet levels between benign conditions and primary BCa, and in BCa cases, between different disease stages. METHODS: Normally voided urine samples were collected from patients with BCa (Total: 183; pTa: 55, pTis: 62, pT1: 24, pT2: 42) and without BCa (Total: 83) on tissue-procurement protocols at three institutions and sMet was measured and normalized to urinary creatinine. Normalized sMet values grouped by pathologic stage were compared using non-parametric tests for correlation and significant difference. ROC analyses were used to derive classification models for patients with or without BCa and patients with or without muscle-invasive BCa (MIBCa or NMIBCa). RESULTS: Urinary sMet levels accurately distinguished patients with BCa from those without (p<0.0001, area under the curve (AUC): 0.7008) with limited sensitivity (61%) and moderate specificity (76%), and patients with MIBCa (n=42) from those with NMIBCa (n=141; p<0.0001, AUC: 0.8002) with moderate sensitivity and specificity (76% and 77%, respectively) and low false negative rate (8%). CONCLUSIONS: Urinary sMet levels distinguish patients with BCa from those without, and patients with or without MIBCa, suggesting the potential utility of urinary sMet as a BCa biomarker for surveillance following initial treatment. Further studies are warranted to determine its potential value for prognosis in advanced disease, predicting treatment response, or identifying patients likely to benefit from Met-targeted therapies.

A 10-year analysis of metastatic prostate cancer as an initial presentation in an underserved population.

OBJECTIVE: To analyze patients from an underserved area who presented initially with metastatic prostate cancer in order to identify patients in our population who would suffer greatly if PSA screening was eliminated. MATERIALS AND METHODS: A prospectively maintained androgen deprivation therapy database from an inner city municipal hospital was queried to identify patients who presented with metastatic prostate cancer. We identified 129 individuals from 1999 to 2009 eligible for study. Those who underwent previous treatment for prostate cancer were excluded. We examined metastatic distribution and analyzed survival using Kaplan Meier probability curves. RESULTS: The median age of presentation was 68 with a median Gleason sum of 8 per prostate biopsy. Thirty-two patients presented with hydronephrosis with a median creatinine of 1.79, two of whom required emergent dialysis. Of those patients who underwent radiographic imaging at presentation, 35.5% (33/93) had lymphadenopathy suspicious for metastasis, 16.1% (15/93) had masses suspicious for visceral metastases. Of the patients who underwent a bone scan 93% (118/127) had positive findings with 7.9% (10/127) exhibiting signs of cord compression. The 2 and 5- year cancer specific survival was 92.1% and 65.6%, respectively. CONCLUSIONS: In this study we have highlighted a group of men in an underserved community who presented with aggressive and morbid PCa despite widespread acceptance of PSA screening.

Program Directors' Perspectives on Residency Applications in the Post‒United States Medical Licensing Examination Step 1 Era: A Case for Standardized Letters of Recommendation?

INTRODUCTION: The United States Medical Licensing Examination (USMLE) Step 1 test evolved into a key metric utilized by program directors (PDs) in assessing candidates for residency. The transition to a USMLE Step 1 binary pass/fail scoring system has resulted in a loss of an important objective assessment. With national movements toward pass/fail systems for clerkship grading and trends toward abandonment of class ranking, assessing residency applications has become increasingly challenging. METHODS: The Society of Academic Urologists convened a task force to, in part, assess the perspectives of urology PDs regarding the importance of various aspects of a residency application for predicting clinical performance. An anonymous survey was disseminated to all urology PDs in the US. Perspectives on 11 potential application predictors of clinical performance and demographics were recorded. Descriptive statistics characterized PD responses. Friedman test and pairwise Wilcoxon tests were used to evaluate the relative ranks assigned to application elements by PDs. RESULTS: There was a 60.5% response rate (89/147). Letters of recommendation (LORs) were ranked as the most important predictor, with a mean rank of 2.39, median of 2 (IQR 1-3). Clerkship grades and USMLE Step 1 were comparable and ranked second. Medical school reputation ranked the lowest. There was significant subjective heterogeneity among categories; however, this was less so for LORs, which predominated as the most important factor among application elements (P < .001). CONCLUSIONS: To our knowledge, this is the largest sample size assessing PD perspectives on application factors that predict clinical performance. The second (clerkship grades) and third (USLME Step 1) most important factors moving toward binary pass/fail systems create an opportunity for actionable change to improve assessment objectivity. Our data demonstrate LORs to be the most important factor of residency applications, making a compelling argument for moving toward a standardized LOR to maximize this tool, mitigate bias, and improve interreviewer reliability.

Gross Hematuria in an Adolescent Secondary to a Rare Bladder Tumor: A Case Report and Review of Inflammatory Myofibroblastic Tumors of the Urinary Bladder.

Inflammatory myofibroblastic tumor (IMT) is a tumor of unknown neoplastic potential that rarely arises in the genitourinary tract. We present the case of an otherwise healthy 16-year old boy with gross hematuria who underwent cystoscopy and transurethral resection of the bladder tumor without complication. Biopsy and immunohistochemistry were consistent with anaplastic lymphoma kinase-positive IMT. In addition to presenting this case of IMT, we review presentations, management and prognosis of bladder IMT.

NCCN Risk Reclassification in Black Men with Low and Intermediate Risk Prostate Cancer After Genomic Testing.

OBJECTIVES: To assess the utility of genomic testing in risk-stratifying Black patients with low and intermediate risk prostate cancer. METHODS: We retrospectively identified 63 Black men deemed eligible for active surveillance based on National Comprehensive Cancer Network (NCCN) guidelines, who underwent OncotypeDx Genomic Prostate Score testing between April 2016 and July 2020. Nonparametric statistical testing was used to compare relevant features between patients reclassified to a higher NCCN risk after genomic testing and those who were not reclassified. RESULTS: The median age was 66 years and median pre-biopsy PSA was 7.3. Initial risk classifications were: very low risk: 7 (11.1%), low risk: 24(38.1%), favorable intermediate risk: 31(49.2%), and unfavorable intermediate risk: 1 (1.6%). Overall, NCCN risk classifications after Genomic Prostate Score testing were significantly higher than initial classifications (P=.003, Wilcoxon signed-rank). Among patients with discordant risk designations, 28(28/40, 70%) were reclassified to a higher NCCN risk after genomic testing. A pre-biopsy prostate specific antigen of greater than 10 did not have significantly higher odds of HBR (OR:2.16 [95% CI: 0.64,7.59, P=.2). Of favorable intermediate risk patients, 20(64.5%) were reclassified to a higher NCCN risk. Ultimately, 18 patients underwent definitive treatment. CONCLUSIONS: Incorporation of genomic testing in risk stratifying Black men with low and intermediate-risk prostate cancer resulted in overall higher NCCN risk classifications. Our findings suggest a role for increased utilization of genomic testing in refining risk-stratification within this patient population. These tests may better inform treatment decisions on an individualized basis.

Primary Small Cell Carcinoma of the Kidney: Disease Characteristics and Treatment Outcomes.

Background: Primary small cell carcinoma of the kidney (PSCCK) is exceedingly rare and data on disease characteristics and outcomes are sparse. This study examines a nationally-representative cancer registry to better characterize PSCCK. Methods: We queried the National Cancer Database to identify patients with histology-confirmed PSCCK from 2004 to 2015. Adjusted Cox proportional hazards regression and Kaplan-Meier analyses were employed to assess predictors of mortality and estimate median survival time, respectively. Results: A total of 110 patients were included (47:53% female:male, 77% ≥60 years of age, 86% Caucasian). Significant predictors of mortality included female sex, age 60-69 years, treatment at an Integrated Network Cancer Program, stage cM1, and lack of surgical and chemoradiotherapy treatment. Independent protective factors were high socioeconomic status and treatment at an Academic Research Program. The estimated median overall survival time was 9.31 (95% CI 7.28-10.98) months for all patients. No differences in estimated survival time were observed across individual treatment modalities among those patients who underwent treatment (p = 0.214). Conclusions: PSCCK is an aggressive malignancy with a median survival time of less than one year. Future studies that correlate clinical tumor staging with specific treatment modalities are needed to optimize and individualize management.

Determinants of adequate lymph node dissection following neoadjuvant chemotherapy in patients with urothelial muscle-invasive bladder cancer: results from the National Cancer Database.

PURPOSE: Recent literature has separately identified multiple determinants of the use of neoadjuvant chemotherapy (NAC) and adherence to pelvic lymph node dissection (PLND) guidelines in the management of non-metastatic bladder cancer. However, such NAC/PLND analyses tend not to account for the other modality, despite the fact that NAC may impact the extent of dissectible lymph nodes. We aimed to determine the predictors of adequate PLND in patients with non-metastatic urothelial muscle-invasive bladder cancer (MIBC) undergoing radical cystectomy (RC) following receipt of NAC. METHODS: We queried the National Cancer Database to identify patients from 2006-2015 with cT2-cT4a/N0M0 urothelial MIBC who underwent RC and were pre-treated with NAC. Multivariate logistic regression analysis was used to identify independent predictors of undergoing an adequate PLND (defined as > 8 nodes). RESULTS: A total of 1518 patients met the criteria for inclusion (74.4% underwent adequate PLND). Adequate PLND was associated with treatment at an academic research facility (OR 2.762 [95% CI 2.119-3.599], p < 0.001). The likelihood of adequate PLND was significantly decreased in patients of older age (0.607 [0.441-0.835], p = 0.002 for age 70-79 years; 0.459 [0.245-0.860], p = 0.015 for age ≥ 80 years), a Charlson-Deyo score of 1 (0.722 [0.537-0.971], p = 0.031), and those who were uninsured (0.530 [0.292-0.964], p = 0.038). CONCLUSIONS: Established predictors of PLND may not necessarily be generalizable to all patients undergoing treatment for bladder cancer. The interplay between PLND and NAC merits further study, particularly in view of recent literature calling into question the survival benefit of PLND in patients pre-treated with NAC.

Impact of neuraxial analgesia on outcomes following radical cystectomy: A systematic review.

Radical cystectomy (RC) is associated with significant morbidity. Neuraxial analgesia is recommended by enhanced recovery after surgery guidelines, but largely supported by evidence extrapolated from colorectal surgery outcomes. We synthesized current evidence regarding short- and long-term outcomes associated with neuraxial analgesia versus patient controlled non-neuraxial analgesia following RC. PubMed, Embase, and Cochrane databases were searched for relevant studies published up to May 2020. Studies reporting complications, length of stay (LOS), pain score, opioid usage within 72 hours, overall survival, cancer-specific survival, and recurrence rate were included. Of 550 identified studies, 9 met criteria for inclusion. Four studies demonstrated a higher percentage of 90-day complications in the neuraxial analgesia cohort. Out of 6 studies reporting information regarding LOS, 4 demonstrated no improvement in LOS in the neuraxial cohort. A reduction in 72 hours post-RC opioid usage was observed in 2 out of 3 studies with available data. Information regarding post-RC pain scores were variable up to 3 days post-RC. One out of 2 studies with available data reported a significant association between neuraxial analgesia and an earlier time to recurrence. No significant associations were seen with respect to overall survival or cancer-specific survival. A majority of low-to-moderate quality evidence demonstrates neuraxial analgesia is associated with a higher rate of complications, variable information regarding pain control, no improvements in LOS, and no significant association with long-term oncological outcomes. Further research regarding the incorporation of nonopiate-based analgesic modalities into RC ERAS protocols is warranted.

Serial prostate biopsies are associated with an increased risk of erectile dysfunction in men with prostate cancer on active surveillance.

PURPOSE: We determined whether serial prostate needle biopsies predispose men to erectile dysfunction and/or lower urinary tract symptoms over time. MATERIALS AND METHODS: Men with prostate cancer on an active surveillance protocol were administered the 5-item Sexual Health Inventory for Men and International Prostate Symptom Score questionnaires on protocol entry, and at a cross-sectional point in 2008. All men had at least 1, 10 to 12-core prostate biopsy at protocol entry and yearly surveillance biopsies thereafter were recommended. RESULTS: Of 333 men 231 returned the followup questionnaires. Correlations were found between biopsy number and erectile dysfunction, with increasing biopsy number associated with a decrease in Sexual Health Inventory for Men score (p = 0.04) and a history of 3 or more biopsies associated with a greater decrease in Sexual Health Inventory for Men score than after 2 or fewer biopsies (p = 0.02). Multivariable analysis for biopsy number, age, prostate volume and prostate specific antigen showed that only biopsy number was associated with decreasing Sexual Health Inventory for Men score (p = 0.02). When men were stratified by baseline Sexual Health Inventory for Men, those without preexisting erectile dysfunction (Sexual Health Inventory for Men score 22 to 25) trended toward steeper decreases in Sexual Health Inventory for Men score after 3 or more biopsies (p = 0.06) than did men with baseline mild to moderate erectile dysfunction (Sexual Health Inventory for Men score 8 to 21). No correlation was found between biopsy number and International Prostate Symptom Score. CONCLUSIONS: Serial prostate biopsies appear to have an adverse effect on erectile function in men with prostate cancer on active surveillance but do not affect lower urinary tract symptoms.

High Grade Mucinous Urothelial Carcinoma of the Renal Collecting System: A Case Report.

High grade mucinous urothelial carcinoma is a rare pathological variant. There is still controversy as to its nomenclature and classification. We report the case of a 64 year old female with history of pelvic pain who was incidentally discovered to have a left upper pole renal mass. Left nephroureterectomy was performed and histopathological examination revealed high grade mucinous urothelial carcinoma. Accurate diagnosis of this distinct pathological entity will allow for better understanding of phenotypic behavior and inform best treatment strategies.

PVT1 Exon 9: A Potential Biomarker of Aggressive Prostate Cancer?

Prostate cancer (PCa) is the most commonly diagnosed cancer as well as the greatest source of cancer-related mortality in males of African ancestry (MoAA). Interestingly, this has been shown to be associated with single nucleotide polymorphisms around regions 2 and 3 of the 8q24 human chromosomal region. The non-protein coding gene locus Plasmacytoma Variant Translocation 1 (PVT1) is located at 8q24 and is overexpressed in PCa and, therefore, is also a candidate biomarker to explain the well-known disparity in this group. PVT1 has at least 12 exons that make separate transcripts which may have different functions, all of which are at present unknown in PCa. Our aim was to determine if any PVT1 transcripts play a role in aggressiveness and racial disparity in PCa. We used a panel of seven PCa cell lines including three derived from MoAA. Ribonucleic acid extraction, complementary deoxyribonucleic acid synthesis, and quantitative polymerase chain reaction (qPCR) were performed to evaluate expression of all 12 PVT1 exons. Each qPCR was performed in quadruplicates. At least four separate qPCR experiments were performed. Expression of PVT1 exons was inconsistent except for exon 9. There was no significant difference in exon 9 expression between cell lines derived from Caucasian males (CM), and an indolent cell line derived from MoAA. However, exon 9 expression in the aggressive MDA PCa 2b and E006AA-hT cell lines derived from MoAA was significantly higher than in other cell lines. Consequently, we observed differential expression of exon 9 of PVT1 in a manner that suggests that PVT1 exon 9 may be associated with aggressive PCa in MoAA.

Changes observed in prostate biopsy practices in an inner city hospital with a high risk patient population following the 2012 USPSTF PSA screening recommendations

ABSTRACT Introduction: We compared characteristics of patients undergoing prostate biopsy in a high-risk inner city population before and after the 2012 USPSTF recommendation against PSA based prostate cancer screening to determine its effect on prostate biopsy practices. Materials and Methods: This was a retrospective study including patients who received biopsies after an abnormal PSA measurement from October 2008-December 2015. Patients with previously diagnosed prostate cancer were excluded. Chi-square tests of independence, two sample t-tests, Mann-Whitney U tests, and Fisher's exact tests were performed. Results: There were 202 and 208 patients in the pre-USPSTF and post-USPSTF recommendation cohorts, respectively. The post-USPSTF cohort had higher median PSA (7.8 versus 7.1ng/mL, p=0.05), greater proportion of patients who were black (96.6% versus 90.5%, p=0.01), and greater percentage of biopsy cores positive for disease (58% versus 29.5%, p<0.001). Multivariable analysis supported that the increase in PSA was independent of the increase in the proportion of patients who were black. The proportion of patients who were classified as D'Amico intermediate and high-risk disease increased in the post-USPSTF cohort and approached statistical significance (70.1% versus 58.8%, p=0.12). Conclusions: Our study suggests that the USPSTF recommendations may have led to an increase in pre-biopsy PSA as well as greater volume of disease. Also, a greater proportion of patients were being classified with intermediate or high risk disease. While the clinical significance of these findings is unknown, what the data suggests is somewhat troubling. Future research should further examine these changes in a larger cohort as well as resultant long-term outcomes.
