Urologist-level variation in the management of T1a renal cell carcinoma: A population-based cohort study.

OBJECTIVES: Lack of strict indications in current guidelines have led to significant variation in management patterns of small renal masses. The impact of the urologist on the management approach for patients with small renal masses has not been explored previously. MATERIALS AND METHODS: Using the linked Surveillance, Epidemiology, and End Results-Medicare database, patients aged ≥66 years diagnosed with small renal masses from January 1, 2004 to December 31, 2013 were identified and assigned to primary urologists. Mixed-effects logistic models were used to evaluate factors associated with different management approaches, estimate urologist-level probabilities of each approach, assess management variation, and determine urologist impact on choice of approach. RESULTS: A total of 12,402 patients with 2,794 corresponding primary urologists were included in the study. At the individual urologist level, the estimated case-adjusted probability of different approaches varied markedly: nonsurgical management (mean, 12.8%; range, 4.9%-36.1%); thermal ablation (mean, 10.8%; range, 2.4%-66.3%); partial nephrectomy (mean, 30.1%; range, 10.1%-66.6%); and radical nephrectomy (mean, 40.4%; range, 17.7%-71.6%). Compared to patient and tumor characteristics, the primary urologist was a more influential measured factor, accounting for 13.6% (vs. 12.9%), 33.8% (vs. 2.1%), 15.1% (vs. 8.4%), and 13.5% (vs. 4.0%) of the variation in management choice for nonsurgical management, thermal ablation, partial nephrectomy, and radical nephrectomy, respectively. CONCLUSIONS: Significant variation exists in the management of small renal masses and appears to be driven primarily by urologist preference and practice patterns. Our findings emphasize the need for unified guidance regarding management of these masses to reduce unwarranted variation in care.

Socioeconomic determinants of racial disparities in survival outcomes among patients with renal cell carcinoma.

PURPOSE: Racially driven outcomes in cancer are challenging to study. Studies evaluating the impact of race in renal cell carcinoma (RCC) outcomes are inconsistent and unable to disentangle socioeconomic disparities from inherent biological differences. We therefore seek to investigate socioeconomic determinants of racial disparities with respect to overall survival (OS) when comparing Black and White patients with RCC. METHODS: We queried the National Cancer Database (NCDB) for patients diagnosed with RCC between 2004 and 2017 with complete clinicodemographic data. Patients were examined across various stages (all, cT1aN0M0, and cM1) and subtypes (all, clear cell, or papillary). We performed Cox proportional hazards regression with adjustment for socioeconomic and disease factors. RESULTS: There were 386,589 patients with RCC, of whom 46,507 (12.0%) were Black. Black patients were generally younger, had more comorbid conditions, less likely to be insured, in a lower income quartile, had lower rates of high school completion, were more likely to have papillary RCC histology, and more likely to be diagnosed at a lower stage of RCC than their white counterparts. By stage, Black patients demonstrated a 16% (any stage), 22.5% (small renal mass [SRM]), and 15% (metastatic) higher risk of mortality than White patients. Survival differences were also evident in histology-specific subanalyses. Socioeconomic factors played a larger role in predicting OS among patients with SRMs than in patients with metastasis. CONCLUSIONS: Black patients with RCC demonstrate worse survival outcomes compared to White patients across all stages. Socioeconomic disparities between races play a significant role in influencing survival in RCC.

Clinicopathologic and Survival After Cystectomy Outcomes in Squamous Cell Carcinoma of the Bladder.

BACKGROUND: Squamous cell carcinoma of the bladder (SqCC) is a rare disease with limited management data. Thus, we sought to characterize the clinicopathologic and survival outcomes amongst patients with SqCC and explore the association of squamous differentiation within urothelial carcinoma (UC w/Squam), as compared to muscle invasive pure UC. METHODS: We conducted a single-center retrospective cohort study of patients, stratified by histology, who underwent cystectomy for MIBC. Baseline clinicopathologic characteristics were compared, and overall survival was assessed using Kaplan-Meier method. RESULTS: We identified 1,034 patients; 37 (3.58%) with SqCC histology, 908 (87.81%) with UC histology, and 89 (8.61%) with UC w/ Squam histology. Among SqCC patients, a higher proportion were Black and similarly a higher proportion were women; amongst patients with UC w/ Squam a higher proportion had lower BMI; and amongst patients with UC a higher proportion had lower clinical (c) T, cN, pathological (p) T, and pN stages. Patients presenting with UC were more likely to receive intravesical therapy; patients presenting with SqCC were less likely to receive neoadjuvant chemotherapy (NAC). Adjuvant chemotherapy rates were similar. With post-hoc Bonferroni analysis, overall survival, cancer-specific survival, and recurrence-free survival were significantly worse for the UC w/ Squam cohort. CONCLUSIONS: UC w/ Squam histology was associated with worse survival outcomes after cystectomy for muscle invasive bladder cancer compared to UC. Our results suggest that UC w/ Squam is associated with more advanced disease compared to UC, warranting further prospective work on consideration of combination therapies for patients with this disease state.

Evaluation of Growth Rates for Small Renal Masses in Elderly Patients Undergoing Active Surveillance.

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

Longitudinal analysis of YouTube videos discussing post-prostatectomy erectile dysfunction.

BACKGROUND: YouTube is heavily utilized by patients as an educational resource, but this content can be fraught with misinformation. We sought to characterize the quality of videos on YouTube discussing postprostatectomy erectile dysfunction and to evaluate metrics associated with retaining a top position in search results over time. METHODS: In October 2019, we watched the first 100 YouTube videos using the search query "radical prostatectomy erectile dysfunction." Videos not relevant to the topic were excluded. Video metrics were collected, and content quality was evaluated using the DISCERN instrument. In June 2022, the search was repeated and video metrics were updated. Video characteristics were associated with search rank and the ability to remain in the top 100 spots using the Pearson correlation coefficient (r) and logistic regression, respectively. RESULTS: We included 81 videos which amassed 529,428 views in 2019. The median total DISCERN score was 29 (IQR 21-42), which is interpreted as a poor quality video. Self-promotion or commercial bias was present in 42 videos (51.9%); false claims were present in 16 (19.8%). There was no correlation between DISCERN score and search rank (r = 0.08, p = 0.49). In 2022, 15 videos remained in the top 100 search results and had a higher median DISCERN score than videos no longer in the top 100 (46 vs. 28.5, p = 0.01). Each additional DISCERN point was associated with a 7% higher odds of remaining in the top 100 (OR 1.07, 95% CI 1.01-1.11, p = 0.003). CONCLUSIONS: The quality of the top 100 YouTube videos discussing postprostatectomy erectile dysfunction is low. Higher quality videos had a higher odds of remaining in the top 100 search results over time but do not correlate with the order in which they are ranked.

The exstrophy experience: A national survey assessing urinary continence, bladder management, and oncologic outcomes in adults.

INTRODUCTION AND OBJECTIVE: The bladder exstrophy-epispadias complex (BEEC) is a rare spectrum of congenital genitourinary malformations with an incidence of 1:10,000 to 1:50,000. Advances in reconstructive surgical techniques have improved clinical outcomes, but there is a paucity in data about disease sequela in adulthood. This is the largest survey to date in the United States exploring the urinary continence, bladder management, and oncologic outcomes in adults with BEEC. METHODS: Respondents were over the age of 18 with a diagnosis of bladder exstrophy, cloacal exstrophy, or epispadias. They were treated at the authors' institution, included in the Association for the Bladder Exstrophy Community (A-BE-C) mailing list, and/or engaged in A-BE-C social media. A survey was created using uniquely designed questions and questionnaires. Survey responses between May 2020 and July 2020 were processed using Research Electronic Data Capture (REDCap). Quantitative and qualitative statistics were used to analyze the data with significance at p < 0.05. RESULTS: A total of 165 patients completed the survey. The median age was 31.5 years (IQR 25.9-45.9). Many patients considered themselves continent of urine, with a median satisfaction score of 74 (IQR 50-97) on a scale from 0 (consider themselves to be completely incontinent) to 100 (consider themselves to be completely continent). There was less leakage among those with a continent urinary diversion compared to those who void or catheterize per urethra (p = 0.003). Patients with intestinal-urinary tract reconstruction, such as augmentation cystoplasty or neobladder creation, were more likely to perform bladder irrigations (p = 0.03). Patients with continent channels were more likely to report UTI than all other forms of bladder management (89.0% vs. 66.2%, p = 0.003). Three (1.9%) patients were diagnosed with bladder cancer. A small portion of patients (27.2%) were given bladder cancer surveillance recommendations by a physician. DISCUSSION: Most patients achieved a satisfactory level of urinary continence, with the highest continence rates in those with a continent urinary diversion. Those with intestinal-urinary tract reconstruction were more likely to perform bladder irrigations, perhaps to avoid complications from intestinal mucous production. The rates of self-reported UTI and were higher in patients with continent channels, but recurrent UTIs were not affected by the type of genitourinary reconstruction. Bladder cancer exists in this population, highlighting the need for long-term follow-up. CONCLUSION: Most BEEC patients achieve a satisfactory level of urinary continence, with the best outcomes in those with a continent urinary diversion. This population requires long-term follow-up with a transitional urologist to ensure adequate oncologic care.

Abdominal Mass in a Phenotypic Female with 46,XY Differences in Sex Development.

We present a case of a large intra-abdominal mass found to be localized pure seminoma within a retained gonad of a 53-year-old phenotypic female with 46,XY differences in sex development (DSD) and androgen insensitivity syndrome (AIS). Our management included extirpation of the mass with contralateral gonadectomy. Historically, patients with AIS would undergo gonadectomy to mitigate the lifetime risk of testicular germ cell tumor development; however, growing evidence suggests safety in retention and surveillance of these gonads into adulthood. This case highlights the importance of lifetime surveillance of patients with 46,XY DSD who elect to retain their gonads.

Characterizing Tumor Thrombus Arising from Non-Clear Cell Renal Cell Carcinoma.

Background: Renal cell carcinoma (RCC) can exhibit a unique vascular tropism that enables tumor thrombus extension into the inferior vena cava (IVC). While most RCC subtypes that form tumor thrombi are of clear cell (cc) histology, non-clear cell (ncc) subtypes can also exhibit this unique growth pattern. Objective: To characterize clinicopathologic differences and survival outcomes among patients with IVC tumor thrombus arising from ccRCC versus nccRCC. Design setting and participants: Patients diagnosed with IVC tumor thrombus secondary to RCC in our institutional experience from 2003 to 2021 were identified. Outcome measurements and statistical analysis: Clinicopathologic characteristics were compared by histology. Perioperative and oncologic outcomes including recurrence-free (RFS), overall (OS), and cancer-specific (CSS) survival were assessed using multivariable Cox regression analyses. Results and limitations: The analyzed cohort included 103 patients (82 ccRCC and 21 nccRCC). There were no significant differences in baseline demographic parameters. Patients with nccRCC were more likely to have regional lymph node involvement (42.9% vs 20.7%, p = 0.037). No differences in perioperative outcomes, IVC resection, or IVC reconstruction were observed between groups. The median follow-up time was 30 mo. The median RFS was 30 (nccRCC) versus 53 (ccRCC) mo (p = 0.1). There was no significant difference in OS or CSS. This study was limited by its small sample size. Conclusions: Patients with IVC tumor thrombus arising from ccRCC and nccRCC exhibit similar perioperative and oncologic outcomes. While surgical appropriateness was not impacted by histologic subtype, multimodal strategies are needed to improve outcomes for patients with tumor thrombus. Patient summary: Renal cell carcinoma (RCC) can uniquely invade vasculature and form a tumor thrombus. This study examined the difference in outcomes of patients with tumor thrombus based on RCC subtype (clear cell vs non-clear cell). We found that patients exhibited similar surgical and survival outcomes regardless of RCC type.

Differential changes in self-reported quality of life in elderly populations after diagnosis of a genitourinary malignancy.

BACKGROUND: The time of cancer diagnosis is a major event during which quality of life (QOL) can be affected and represents a crucial time to identify patients at high risk of decline. We sought to compare the differential effects of the diagnosis of 3 major urologic malignancies on QOL. METHODS: The Surveillance, Epidemiology, and End Results-Medicare Health Outcomes Survey database was queried for patients who completed a QOL questionnaire (SF-36 or VR-12) before and after a diagnosis of bladder, kidney, or prostate cancer. Primary outcome measures were the mental component summary (MCS), and physical component summary (PCS) scores. Mixed effects linear regression was performed with cancer diagnosis as the primary variable of interest, with race and cardiovascular comorbidity status included as potentially confounding independent variables. RESULTS: There were 3,258 patients with urologic cancers. Both MCS and PCS scores dropped after diagnosis in all disease states. Bladder and kidney cancer patients demonstrated the greatest decline in MCS score (-1.762 points, 95% CI-2.571 to -0.952, P < 0.001) and PCS score (-3.769 points, 95% CI-5.042 to -2.496, P < 0.001), respectively, after adjustment for potential confounders. By contrast, prostate cancer patients demonstrated the smallest decline in both domains. Race and cardiovascular comorbidity status were independently associated with QOL, with an association 2 to 3 times greater than that of cancer diagnosis. CONCLUSIONS: Diagnosis of a urologic cancer was associated with a decline in patient-reported QOL, particularly in those with bladder or kidney cancer. Changes in physical health were more prominent than in mental health. Race and cardiovascular comorbidity status influenced QOL domains to a greater extent than specific urologic cancer diagnosis.

Deploying the Behavioral and Environmental Sensing and Intervention for Cancer Smart Health System to Support Patients and Family Caregivers in Managing Pain: Feasibility and Acceptability Study.

BACKGROUND: Distressing cancer pain remains a serious symptom management issue for patients and family caregivers, particularly within home settings. Technology can support home-based cancer symptom management but must consider the experience of patients and family caregivers, as well as the broader environmental context. OBJECTIVE: This study aimed to test the feasibility and acceptability of a smart health sensing system-Behavioral and Environmental Sensing and Intervention for Cancer (BESI-C)-that was designed to support the monitoring and management of cancer pain in the home setting. METHODS: Dyads of patients with cancer and their primary family caregivers were recruited from an outpatient palliative care clinic at an academic medical center. BESI-C was deployed in each dyad home for approximately 2 weeks. Data were collected via environmental sensors to assess the home context (eg, light and temperature); Bluetooth beacons to help localize dyad positions; and smart watches worn by both patients and caregivers, equipped with heart rate monitors, accelerometers, and a custom app to deliver ecological momentary assessments (EMAs). EMAs enabled dyads to record and characterize pain events from both their own and their partners' perspectives. Sensor data streams were integrated to describe and explore the context of cancer pain events. Feasibility was assessed both technically and procedurally. Acceptability was assessed using postdeployment surveys and structured interviews with participants. RESULTS: Overall, 5 deployments (n=10 participants; 5 patient and family caregiver dyads) were completed, and 283 unique pain events were recorded. Using our "BESI-C Performance Scoring Instrument," the overall technical feasibility score for deployments was 86.4 out of 100. Procedural feasibility challenges included the rurality of dyads, smart watch battery life and EMA reliability, and the length of time required for deployment installation. Postdeployment acceptability Likert surveys (1=strongly disagree; 5=strongly agree) found that dyads disagreed that BESI-C was a burden (1.7 out of 5) or compromised their privacy (1.9 out of 5) and agreed that the system collected helpful information to better manage cancer pain (4.6 out of 5). Participants also expressed an interest in seeing their own individual data (4.4 out of 5) and strongly agreed that it is important that data collected by BESI-C are shared with their respective partners (4.8 out of 5) and health care providers (4.8 out of 5). Qualitative feedback from participants suggested that BESI-C positively improved patient-caregiver communication regarding pain management. Importantly, we demonstrated proof of concept that seriously ill patients with cancer and their caregivers will mark pain events in real time using a smart watch. CONCLUSIONS: It is feasible to deploy BESI-C, and dyads find the system acceptable. By leveraging human-centered design and the integration of heterogenous environmental, physiological, and behavioral data, the BESI-C system offers an innovative approach to monitor cancer pain, mitigate the escalation of pain and distress, and improve symptom management self-efficacy.

Active Surveillance versus Immediate Intervention for Small Renal Masses: A Cost-Effectiveness and Clinical Decision Analysis.

PURPOSE: Active surveillance (AS) with the possibility of delayed intervention (DI) is emerging as a safe alternative to immediate intervention for many patients with small renal masses (SRMs). However, limited comparative data exist to inform the most appropriate management strategy for SRMs. MATERIALS AND METHODS: Decision analytic Markov modeling was performed to estimate the health outcomes and costs of 4 management strategies for 65-year-old patients with an incidental SRM: AS (with possible DI), immediate partial nephrectomy, radical nephrectomy, and thermal ablation. Mortality, direct medical costs, quality-adjusted life-years, and incremental cost-effectiveness ratios were evaluated over 10 years. RESULTS: The 10-year all-cause mortality was 22.6% for AS, 21.9% for immediate partial nephrectomy, 22.4% for immediate radical nephrectomy, and 23.7% for immediate thermal ablation. At a willingness-to-pay threshold of $100,000/quality-adjusted life-year, AS was the most cost-effective management strategy. The results were robust in univariate, multivariate, and probabilistic sensitivity analyses. Clinical decision analysis demonstrated that the tumor's metastatic potential, patient age, individual preferences, and health status were important factors influencing the optimal management strategy. Notably, if the annual probability of metastatic progression from AS was sufficiently low (under 0.35%-0.45% for most ages at baseline), consistent with the typical metastatic potential of SRMs <2 cm, AS would achieve higher health utilities than the other strategies. CONCLUSIONS: Compared to immediate intervention, AS with timely DI offers a safe and cost-effective approach to managing patients with SRMs. For patients harboring tumors of very low metastatic potential, AS may lead to better patient outcomes than immediate intervention.

Residual CIS after neoadjuvant chemotherapy and radical cystectomy for muscle invasive bladder cancer: Implications for neoadjuvant trials.

PURPOSE: To better define surrogate endpoints for neoadjuvant chemotherapy (NAC) trials in patients with muscle-invasive bladder cancer. We compared survival in patients with carcinoma in-situ (CIS) only vs. complete response following NAC and radical cystectomy (RC). MATERIALS AND METHODS: Patients with cT2-4N0M0 disease treated with NAC and RC between 2001 and 2018 were stratified by response: complete response (CR, pT0N0), partial response (PR, pTaN0, pT1N0+/-CIS), CIS-only (pTisN0), stable disease (SD, pT2N0), or progressive disease (PD, >pT2N0). Primary endpoints were overall survival (OS) and risk of recurrence in patients with CIS-only vs. CR. Multivariable Cox proportional hazards regression model was used for OS and a competing risks proportional hazards model was used for risk of recurrence. RESULTS: Of 1,406 patients in our institution cohort, 340 patients met inclusion criteria. Kaplan-Meier mean estimates of OS for CR and CIS-only were 108.9 months (95% CI 89.7-127.9) and 125.8 months (95% CI 112.3-139.3), respectively (P = 0.13). Cox proportional hazards model found no difference in OS between patients with PR (HR 1.06, 95% CI 0.33-2.58, P = 0.897) or CIS-only (HR 0.422, 95% CI 0.15-1.18, P = 0.101) when compared to CR. The risk of recurrence was similar between patients with CIS-only (HR 0.73, 95% 0.29-1.84, P = 0.49) and PR (HR 1.32, 95% CI 0.54-3.29, P = 0.54) when compared to CR on competing risks analysis. CONCLUSIONS: Residual CIS-only after NAC and RC demonstrated similar survival outcomes when compared to patients with pathologic CR. Further study in large multi-institutional cohorts may further validate CIS-only as an additional surrogate endpoint after NAC and may inform future trials.

Self-reported quality of life as a predictor of mortality in renal cell carcinoma.

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

Using Competing Risk of Mortality to Inform the Transition from Prostate Cancer Active Surveillance to Watchful Waiting.

BACKGROUND: For men on active surveillance (AS) for prostate cancer (PCa), disease progression and age-related changes in health may influence decisions about pursuing curative treatment. OBJECTIVE: To evaluate the predicted PCa and non-PCa mortality at the time of reclassification among men on AS, to identify clinical criteria for considering a transition from AS to watchful waiting (WW). DESIGN, SETTING, AND PARTICIPANTS: Patients enrolled in a large AS program who experienced biopsy grade reclassification (Gleason grade increase) were retrospectively examined. All patients who had complete documentation of medical comorbidities at reclassification were included. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: A validated model was used to assess 10- and 15-yr untreated PCa and non-PCa mortalities based on patient comorbidities and PCa clinical characteristics. We compared the ratio of predicted PCa mortality with predicted non-PCa mortality ("predicted mortality ratio") and divided patients into four risk tiers based on this ratio: (1) tier 1 (ratio: >0.33), (2) tier 2 (ratio 0.33-0.20), (3) tier 3 (ratio 0.20-0.10), and (4) tier 4 (ratio <0.10). RESULTS AND LIMITATIONS: Of the 344 men who were reclassified, 98 (28%) were in risk tier 1, 85 (25%) in tier 2, 93 (27%) in tier 3, and 68 (20%) in tier 4 for 10-yr mortality. Fifteen-year risk tiers were distributed similarly. The 23 (6.7%) men who met the "transition triad" (age >75 yr, Charlson Comorbidity Index >3, and grade group ≤2) had a 14-fold higher non-PCa mortality risk and a lower predicted mortality ratio than those who did not (0.07 vs 0.23, p < 0.001). The primary limitations of our study included its retrospective nature and the use of predicted mortalities. CONCLUSIONS: At reclassification, nearly half of patients had a more than five-fold and one in five patients had a more than ten-fold higher risk of non-PCa death than patients having a risk of untreated PCa death. Despite a more significant cancer diagnosis, a transition to WW for older men with multiple comorbidities and grade group <3 PCa should be considered. PATIENT SUMMARY: Men with favorable-risk prostate cancer and life expectancy of >10 yr are often enrolled in active surveillance, which entails delay of curative treatment until there is evidence of more aggressive disease. We examined a group of men on active surveillance who developed more aggressive disease, and found, nevertheless, that the majority of these men continued to have a dramatically higher risk of death from non-prostate cancer causes than from prostate cancer based on a risk prediction tool. For men older than 75 yr, who have multiple medical conditions and who do not have higher-grade cancer, it may be reasonable to reconsider the need for curative treatment given the low risk of death from prostate cancer compared with the risk of death from other causes.

Management of Urethral Hemangioma.

Hemangiomas are benign proliferations of blood vessels, and urethral hemangiomas are extremely rare presentations of this condition. As the condition is quite rare, there is very little literature about best management strategies. The best resources for determining management are case reports which focus on treatment via transurethral ablation or endoscopic resection. However, there is no guidance on management of urethral hemangiomas which are refractory to these minimally invasive methods. Herein, we summarize the literature for urethral hemangioma management, present the case of a male presenting with refractory hematuria due to a hemangioma in the penile urethra, and describe the operative technique for the open excision and reconstruction of this hemangioma.

Performance of a Prostate-Specific Membrane Antigen Positron Emission Tomography/Computed Tomography-Derived Risk-Stratification Tool for High-risk and Very High-risk Prostate Cancer.

Importance: Prostate-specific membrane antigen (PSMA) positron emission tomography/computed tomography (PET/CT) can detect low-volume, nonlocalized (ie, regional or metastatic) prostate cancer that was occult on conventional imaging. However, the long-term clinical implications of PSMA PET/CT upstaging remain unclear. Objectives: To evaluate the prognostic significance of a nomogram that models an individual's risk of nonlocalized upstaging on PSMA PET/CT and to compare its performance with existing risk-stratification tools. Design, Setting, and Participants: This cohort study included patients diagnosed with high-risk or very high-risk prostate cancer (ie, prostate-specific antigen [PSA] level >20 ng/mL, Gleason score 8-10, and/or clinical stage T3-T4, without evidence of nodal or metastatic disease by conventional workup) from April 1995 to August 2018. This multinational study was conducted at 15 centers. Data were analyzed from December 2020 to March 2021. Exposures: Curative-intent radical prostatectomy (RP), external beam radiotherapy (EBRT), or EBRT plus brachytherapy (BT), with or without androgen deprivation therapy. Main Outcomes and Measures: PSMA upstage probability was calculated from a nomogram using the biopsy Gleason score, percentage positive systematic biopsy cores, clinical T category, and PSA level. Biochemical recurrence (BCR), distant metastasis (DM), prostate cancer-specific mortality (PCSM), and overall survival (OS) were analyzed using Fine-Gray and Cox regressions. Model performance was quantified with the concordance (C) index. Results: Of 5275 patients, the median (IQR) age was 66 (60-72) years; 2883 (55%) were treated with RP, 1669 (32%) with EBRT, and 723 (14%) with EBRT plus BT; median (IQR) PSA level was 10.5 (5.9-23.2) ng/mL; 3987 (76%) had Gleason grade 8 to 10 disease; and 750 (14%) had stage T3 to T4 disease. Median (IQR) follow-up was 5.1 (3.1-7.9) years; 1221 (23%) were followed up for at least 8 years. Overall, 1895 (36%) had BCR, 851 (16%) developed DM, and 242 (5%) died of prostate cancer. PSMA upstage probability was significantly prognostic of all clinical end points, with 8-year C indices of 0.63 (95% CI, 0.61-0.65) for BCR, 0.69 (95% CI, 0.66-0.71) for DM, 0.71 (95% CI, 0.67-0.75) for PCSM, and 0.60 (95% CI, 0.57-0.62) for PCSM (P < .001). The PSMA nomogram outperformed existing risk-stratification tools, except for similar performance to Staging Collaboration for Cancer of the Prostate (STAR-CAP) for PCSM (eg, DM: PSMA, 0.69 [95% CI, 0.66-0.71] vs STAR-CAP, 0.65 [95% CI, 0.62-0.68]; P < .001; Memorial Sloan Kettering Cancer Center nomogram, 0.57 [95% CI, 0.54-0.60]; P < .001; Cancer of the Prostate Risk Assessment groups, 0.53 [95% CI, 0.51-0.56]; P < .001). Results were validated in secondary cohorts from the Surveillance, Epidemiology, and End Results database and the National Cancer Database. Conclusions and Relevance: These findings suggest that PSMA upstage probability is associated with long-term, clinically meaningful end points. Furthermore, PSMA upstaging had superior risk discrimination compared with existing tools. Formerly occult, PSMA PET/CT-detectable nonlocalized disease may be the main driver of outcomes in high-risk patients.

Contemporary considerations in the management and treatment of lower pole stones

ABSTRACT The presence of lower pole stones poses a unique challenge due to the anatomical considerations involved in their management and treatment. Considerable research has been performed to determine the optimal strategy when faced with this highly relevant clinical scenario. Standard options for management include observation, shock wave lithotripsy, retrograde intrarenal surgery, or percutaneous nephrolithotomy. Indeed, each approach confers a distinct set of risks and benefits, which must be placed into the context of patient preference and expected outcomes. The current state of practice reflects a combination of lessons learned from managing calculi not only in the lower pole, but also from other locations within the kidney as well.

Comparison of Multimodal Therapies and Outcomes Among Patients With High-Risk Prostate Cancer With Adverse Clinicopathologic Features.

Importance: The optimal management strategy for high-risk prostate cancer and additional adverse clinicopathologic features remains unknown. Objective: To compare clinical outcomes among patients with high-risk prostate cancer after definitive treatment. Design, Setting, and Participants: This retrospective cohort study included patients with high-risk prostate cancer (as defined by the National Comprehensive Cancer Network [NCCN]) and at least 1 adverse clinicopathologic feature (defined as any primary Gleason pattern 5 on biopsy, clinical T3b-4 disease, ≥50% cores with biopsy results positive for prostate cancer, or NCCN ≥2 high-risk features) treated between 2000 and 2014 at 16 tertiary centers. Data were analyzed in November 2020. Exposures: Radical prostatectomy (RP), external beam radiotherapy (EBRT) with androgen deprivation therapy (ADT), or EBRT plus brachytherapy boost (BT) with ADT. Guideline-concordant multimodal treatment was defined as RP with appropriate use of multimodal therapy (optimal RP), EBRT with at least 2 years of ADT (optimal EBRT), or EBRT with BT with at least 1 year ADT (optimal EBRT with BT). Main Outcomes and Measures: The primary outcome was prostate cancer-specific mortality; distant metastasis was a secondary outcome. Differences were evaluated using inverse probability of treatment weight-adjusted Fine-Gray competing risk regression models. Results: A total of 6004 men (median [interquartile range] age, 66.4 [60.9-71.8] years) with high-risk prostate cancer were analyzed, including 3175 patients (52.9%) who underwent RP, 1830 patients (30.5%) who underwent EBRT alone, and 999 patients (16.6%) who underwent EBRT with BT. Compared with RP, treatment with EBRT with BT (subdistribution hazard ratio [sHR] 0.78, [95% CI, 0.63-0.97]; P = .03) or with EBRT alone (sHR, 0.70 [95% CI, 0.53-0.92]; P = .01) was associated with significantly improved prostate cancer-specific mortality; there was no difference in prostate cancer-specific mortality between EBRT with BT and EBRT alone (sHR, 0.89 [95% CI, 0.67-1.18]; P = .43). No significant differences in prostate cancer-specific mortality were found across treatment cohorts among 2940 patients who received guideline-concordant multimodality treatment (eg, optimal EBRT alone vs optimal RP: sHR, 0.76 [95% CI, 0.52-1.09]; P = .14). However, treatment with EBRT alone or EBRT with BT was consistently associated with lower rates of distant metastasis compared with treatment with RP (eg, EBRT vs RP: sHR, 0.50 [95% CI, 0.44-0.58]; P < .001). Conclusions and Relevance: These findings suggest that among patients with high-risk prostate cancer and additional unfavorable clinicopathologic features receiving guideline-concordant multimodal therapy, prostate cancer-specific mortality outcomes were equivalent among those treated with RP, EBRT, and EBRT with BT, although distant metastasis outcomes were more favorable among patients treated with EBRT and EBRT with BT. Optimal multimodality treatment is critical for improving outcomes in patients with high-risk prostate cancer.

Resident involvement in the prostatic urethral lift: implementing innovative technology in an academic setting.

Adoption of the prostatic urethral lift (PUL) as a treatment for benign prostatic hyperplasia highlights the importance of training residents with novel technology without compromising patient care. This study examines the effect of resident involvement during PUL on patient and procedural outcomes. Retrospective chart review was conducted on all consecutive PUL cases performed by a single academic urologist between October 2017 and November 2019. Trainees in post-graduate year (PGY) 1-3 are considered junior residents, while those in PGY 4-6 are senior residents. The International Prostate Symptom Score (IPSS) and quality of life (QOL) scores were used to measure outcomes. Simple and mixed-effects linear regression models were used to compare differences. There were 110 patients with a median age of 66.4 years. Residents were involved in 73 cases (66.4%), and senior residents were involved in 31 of those cases. Resident involvement was not associated with adverse perioperative outcomes with respect to the number of implants fired, the percentage of implants successfully placed, or the postoperative catheterization rate. After adjustment for confounding factors, junior residents were associated with significantly longer case length compared to the attending alone (+12.6 min, P = 0.003) but senior residents were not (+2.4 min, P = 0.59). IPSS and QOL scores were not significantly affected by resident involvement (P = 0.12 and P = 0.21, respectively). The presence of surgeons-in-training, particularly those in the early stages, prolongs PUL case length but does not appear to have an adverse impact on patient outcomes.
