Prostate Health Index Density Outperforms Prostate-specific Antigen Density in the Diagnosis of Clinically Significant Prostate Cancer in Equivocal Magnetic Resonance Imaging of the Prostate: A Multicenter Evaluation.

PURPOSE: We compare Prostate Health Index, Prostate Health Index density, and PSA density in predicting clinically significant prostate cancer in MRI-guided prostate biopsy. MATERIALS AND METHODS: This is a multicenter evaluation of prospectively maintained prostate biopsy databases at 10 urology centers. Men with Prostate Health Index and MRI-guided targeted and systematic prostate biopsy performed and without prior prostate cancer diagnosis were included. The additional value of PSA density, Prostate Health Index, and Prostate Health Index density to MRI PI-RADS (Prostate Imaging Reporting & Data System) score was evaluated with multivariable analyses, area under the curve, and decision curve analyses. The proportion of unnecessary biopsies that can be avoided are estimated for clinically significant prostate cancer (International Society of Urological Pathology group ≥2 prostate cancer). RESULTS: A total of 1,215 men were analyzed. Prostate cancer and clinically significant prostate cancer were diagnosed in 51% (617/1,215) and 35% (422/1,215) of men, respectively. Clinically significant prostate cancer was diagnosed in 4.4% (3/68), 15% (72/470), 39% (176/446), and 74% (171/231) of highest PI-RADS score of 2, 3, 4, and 5 lesions, respectively. In multivariable analyses, independent predictors for clinically significant prostate cancer detection included Prostate Health Index (OR 1.04), prostate volume (OR 0.97), and PI-RADS score 4 (OR 2.81) and 5 (OR 8.34). Area under the curve for clinically significant prostate cancer of PI-RADS + Prostate Health Index density (0.85) was superior to PI-RADS + PSA density (0.81), Prostate Health Index density (0.81), Prostate Health Index (0.78), PI-RADS (0.76), PSA density (0.72), and PSA (0.60) in the whole cohort, and the superiority of Prostate Health Index density was also observed in PI-RADS 3 lesions. Decision curve analysis showed Prostate Health Index density achieving the best net clinical benefit in PI-RADS 3 or 4 cases. Among PI-RADS 3 lesions, using cutoffs of PSA density 0.15, Prostate Health Index 38.0, and Prostate Health Index density 0.83 could reduce 58%, 67%, and 72% of unnecessary biopsies, respectively. CONCLUSIONS: Prostate Health Index density outperformed Prostate Health Index or PSA density in clinically significant prostate cancer detection in men with multiparametric MRI performed, and further reduced unnecessary biopsies in PI-RADS 3 lesions.

Testicular self-examination for early detection of testicular cancer.

Testicular cancer (TCa) commonly presents as a painless scrotal mass. It has been suggested that testicular self-examination (TSE) can help in early detection and thus potentially improve treatment outcomes and prognosis. While TSE is more well established in guideline recommendations for patients with a known history of TCa, its role in healthy young men is less established and controversial. In this paper, we review contemporary data to provide an updated recommendation.

Delayed surgery for localised and metastatic renal cell carcinoma: a systematic review and meta-analysis for the COVID-19 pandemic.

PURPOSE: The COVID-19 pandemic has led to the cancellation or deferment of many elective cancer surgeries. We performed a systematic review on the oncological effects of delayed surgery for patients with localised or metastatic renal cell carcinoma (RCC) in the targeted therapy (TT) era. METHOD: The protocol of this review is registered on PROSPERO(CRD42020190882). A comprehensive literature search was performed on Medline, Embase and Cochrane CENTRAL using MeSH terms and keywords for randomised controlled trials and observational studies on the topic. Risks of biases were assessed using the Cochrane RoB tool and the Newcastle-Ottawa Scale. For localised RCC, immediate surgery [including partial nephrectomy (PN) and radical nephrectomy (RN)] and delayed surgery [including active surveillance (AS) and delayed intervention (DI)] were compared. For metastatic RCC, upfront versus deferred cytoreductive nephrectomy (CN) were compared. RESULTS: Eleven studies were included for quantitative analysis. Delayed surgery was significantly associated with worse cancer-specific survival (HR 1.67, 95% CI 1.23-2.27, p < 0.01) in T1a RCC, but no significant difference was noted for overall survival. For localised ≥ T1b RCC, there were insufficient data for meta-analysis and the results from the individual reports were contradictory. For metastatic RCC, upfront TT followed by deferred CN was associated with better overall survival when compared to upfront CN followed by deferred TT (HR 0.61, 95% CI 0.43-0.86, p < 0.001). CONCLUSION: Noting potential selection bias, there is insufficient evidence to support the notion that delayed surgery is safe in localised RCC. For metastatic RCC, upfront TT followed by deferred CN should be considered.

Wunderlich syndrome secondary to cyst rupture and concurrent anticoagulation.

Wunderlich syndrome (WS) is a rare triad of flank pain, flank mass and hypovolemic shock and is classically attributed to angiomyolipomata or neoplasms. Treatment is guided by clinical severity: conservative, selective arterial embolization, or nephrectomy. We report an atypical case of a 69-year old man with a pre-existing 9 cm left renal tumor who developed WS secondary to anticoagulation and simple cyst rupture from his contralateral kidney, complicated by abdominal compartment syndrome with hemodynamic instability despite inotropic support and robust resuscitation. Early recognition and source control via radical nephrectomy were essential in securing a positive outcome.

Trends in penile prosthesis implantation and analysis of predictive factors for removal.

PURPOSE: This study aims to analyze patient demographics, hospital characteristics, and clinical risk factors which predict penile prosthesis removal. We also examine costs of penile prosthesis removal and trends in inflatable versus non-inflatable penile prostheses implantation in the USA from 2003 to 2015. METHODS: Cross-sectional analysis from Premier Perspective Database was completed using data from 2003 to 2015. We compared the relative proportion of inflatable versus non-inflatable penile prostheses implanted. We separated the prosthesis removal group based on indication for removal-Group 1 (infection), Group 2 (mechanical complication), and Group 3 (all explants). All groups were compared to a control group of patients with penile implants who were never subsequently explanted. Multivariate analysis was performed to analyze patient and hospital factors which predicted removal. Cost comparison was performed between the explant groups. RESULTS: There were 5085 penile prostheses implanted with a stable relative proportion of inflatable versus non-inflatable prosthesis over the 13-year study period. There were 3317 explantations. Patient factors associated with prosthesis removal were non-black race, Charlson Comorbidity Index, diabetes, and HIV status. Hospital factors associated with removal included non-teaching status, hospital region, year of removal, and annual surgeon volume. Median hospitalization costs of all explantations were $10,878. Explantations due to infection cost $11,252 versus $8602 for mechanical complications. CONCLUSIONS: This large population-based study demonstrates a stable trend in inflatable versus non-inflatable prosthesis implantation. We also identify patient and hospital factors that predict penile prosthesis removal which has clinical utility for patient risk stratification and counseling.

SIU-ICUD consultation on bladder cancer: treatment of muscle-invasive bladder cancer.

PURPOSE: To provide a comprehensive overview and update of the Joint Société Internationale d'Urologie-International Consultation on Urological Diseases (SIU-ICUD) Consultation on Bladder Cancer for muscle-invasive presumably node-negative bladder cancer (MIBC). METHODS: Contemporary literature was analyzed for the latest evidence in treatment options, outcomes, including radical surgery, neoadjuvant and adjuvant treatment modalities, and bladder-sparing approaches. An international multi-disciplinary expert panel evaluated and graded the data according to guidelines from the Oxford Centre for Evidence-Based Medicine. RESULTS: Radical cystectomy (RC) is the standard of care for MIBC patients considered to be surgical candidates. While associated with substantial morbidity and mortality, this has been mitigated with improved technique, minimally invasive technology, and better perioperative care pathways (e.g., enhanced recovery after surgery). Neoadjuvant (NA) cisplatin-based combination chemotherapy improves overall survival and should be offered to eligible ≥ cT2N0 patients. Adjuvant (Adj) cisplatin-based combination chemotherapy may be considered, particularly for pT3-4 and/or pN+ disease without prior NA chemotherapy. Trimodal bladder-preserving treatment via maximum transurethral resection of bladder tumor followed by concurrent chemoradiation is safe and, when combined with early salvage RC for recurrence, offers long-term survival rates in selected patients comparable to RC. Immunotherapy is still experimental and is given either alone or in combination with chemotherapy and/or radiation. CONCLUSION: A multi-disciplinary approach is paramount to achieving optimal outcomes for MIBC patients, irrespective of their age, performance and nutritional status, fitness/frailty, renal and other organ function, or disease severity.

Variation in the use of active surveillance for low-risk prostate cancer.

BACKGROUND: This study assessed the use of active surveillance in men with low-risk prostate cancer and evaluated institutional factors associated with the receipt of active surveillance. METHODS: A retrospective, hospital-based cohort of 115,208 men with low-risk prostate cancer diagnosed between 2010 and 2014 was used. Multivariate and mixed effects models were used to examine variation and factors associated with active surveillance. RESULTS: During the study period, the use of active surveillance increased from 6.8% in 2010 to 19.9% in 2014 (estimated annual percentage change, +28.8%; 95% confidence interval [CI], + 19.6% to + 38.7%; P = .002). The adjusted probability of active-surveillance receipt by institution was highly variable. Compared with patients treated at comprehensive community cancer centers, patients treated at community cancer programs (odds ratio [OR], 2.00; 95% CI, 1.50-2.67; P < .001) and academic institutions (OR, 2.47; 95%, CI, 1.81-3.37; P < .001) had higher odds of receiving active surveillance. Compared with patients treated at very low-volume facilities, patients treated at very high-volume facilities had higher odds of receiving active surveillance (OR, 3.57; 95% CI, 1.94-6.55; P < .001). Patient and hospital characteristics accounted for 60.2% of the overall variation, whereas the treating institution accounted for 91.5% of the unexplained variability. CONCLUSIONS: Within this hospital-based cohort, the use of active surveillance for low-risk prostate cancer increased significantly over time. Significant variation was found in the use of active surveillance. Most of the variation was attributable to facility-related factors such as the facility type, facility volume, and institution. Policies to achieve consistent and higher rates of active surveillance, when appropriate, should be a priority of professional societies and patient advocacy groups.

Prostate Cancer Screening in Early Medicaid Expansion States.

PURPOSE: The PPACA (Patient Protection and Affordable Care Act) of 2010 included a provision to expand Medicaid by 2014. Six states and jurisdictions elected to expand Medicaid early before 2012. This provided a natural experiment to test the association between expanded insurance coverage and preventive service utilization, including prostate cancer screening. MATERIALS AND METHODS: Using the 2012 and 2014 BRFSS (Behavioral Risk Factor Surveillance System) surveys we identified men 40 to 64 years old who reported prostate specific antigen testing in the preceding 12 months. Sociodemographic and access to care variables were extracted. Income was stratified by the relationship to Medicaid eligibility and the federal poverty level (less than 138%, 138% to 400% and greater than 400%). The weighted prevalence of prostate specific antigen was estimated. Multivariable logistic regression models were used to evaluate factors associated with prostate specific antigen screening. Interaction analysis for Medicaid expansion was performed. RESULTS: Among 158,103 respondents individuals in nonexpansion states had the highest incidence of prostate specific antigen screening. Nationally screening decreased between 2011 and 2013 (OR 0.87, 95% CI 0.83-0.91). In only early expansion states there was a 3% absolute increase in screening among men in the less than 138% federal poverty level, which was associated with expansion status (pinteraction = 0.04). Increased screening in early expansion states was also seen in men who were 55 to 59 years old, nonHispanic African American, Hispanic, previously married, not high school graduates and current smokers. CONCLUSIONS: Between 2011 and 2013 there were national declines in prostate cancer screening. However, there was significant narrowing of the gap in prostate specific antigen screening between higher and low income men in Medicaid early expansion states. This may reflect improved access to preventive services among populations with historic barriers to care.

Associations of specific postoperative complications with costs after radical cystectomy.

OBJECTIVE: To quantify the financial impact of complications after radical cystectomy (RC) and their associations with respective 90-day costs, as RC is a morbid surgery plagued by complications and the expenditure attributed to specific complications after RC is not well characterised. PATIENTS AND METHODS: We used the Premier Hospital Database (Premier Inc., Charlotte, NC, USA) to identify 9 137 RC patients (weighted population of 57 553) from 360 hospitals between 2003 and 2013. Complications were categorised according to Agency for Healthcare Research and Quality Clinical Classifications. Patients with and without complications were compared, and multivariable analysis was performed. RESULTS: An index complication increased costs by $9 262 (95% confidence interval [CI] 8 300-10 223) and a readmission complication increased costs by $20 697 (95% CI 18 735-22 660). The four most costly index complications (descending order) were venous thromboembolism (VTE), infection, wound and soft tissue complications, and pulmonary complications (P < 0.001, vs no complication). A complication increased length of stay by 4 days (95% CI 3.6-4.3). One in five patients were readmitted in 90 days and the four costliest readmission complications (descending order) were pulmonary, bleeding, VTE, and gastrointestinal complications (P < 0.001, vs no complication). Readmitted patients had multiple complications upon readmission (median of 3, interquartile range 2-4). On multivariable analysis, more comorbidities, longer surgery (>6 h), transfusions of >3 units, and teaching hospitals were associated with higher costs (P < 0.05), whilst high-volume surgeons and shorter surgeries (<4 h) were associated with lower costs (P < 0.05). CONCLUSIONS: Complications after RC increase index and readmission costs for hospitals, and can be categorised based on magnitude. Future initiatives in RC may also consider costs of complications when establishing quality improvement priorities for patients, providers, or policymakers.

Comparison of health-related quality of life (HRQoL) between ileal conduit diversion and orthotopic neobladder based on validated questionnaires: a systematic review and meta-analysis.

PURPOSE: The question of whether orthotopic neobladder (ONB) reconstruction is superior to ileal conduit diversion (ICD) with respect to health-related quality of life (HRQoL) remains controversial. The goal of this study is to perform a meta-analysis to compare post-ICD and post-ONB HRQoL in patients with bladder cancer. METHODS: A systematic search of Medline, Embase, the Cochrane Central Register of Controlled Trials, and the annual congress abstracts of the European Association of Urology (EAU), the American Urological Association (AUA) and the Société Internationale d'Urologie (SIU) up to June 2017 was conducted to identify all relevant clinical trials using validated questionnaires to assess HRQoL. A systematic review and meta-analysis were then performed. RESULTS: A total of 2507 patients from 26 eligible studies were included. Meta-analyses showed significant differences favouring ONB patients in global health status (WMD + 9.13, p = 0.004), physical functioning (WMD + 11.57, p = 0.0001), role functioning (WMD + 9.64, p = 0.002), and social functioning (WMD + 6.81, p = 0.03) based on the EORTC-QLQ-C30 questionnaire and in the total score of FACT questionnaire (WMD + 6.80, p = 0.001). However, ONB patients were more likely to have postoperative urinary symptoms than ICD patients (WMD - 22.19, p = 0.0001). CONCLUSIONS: ONB patients are more likely to have a better global health status than ICD patients. Regardless of the type of urinary diversion (UD) surgery, a gradual improvement in HRQoL over preoperative status tended to stabilise after 12 months postoperatively.

Patient driven care in the management of prostate cancer: analysis of the United States military healthcare system.

BACKGROUND: Patient preferences are assumed to impact healthcare resource utilization, especially treatment options. There is limited data exploring this phenomenon. We sought to identify factors associated with patients transferring care for prostatectomy, from military to civilian facilities, and the receipt of minimally invasive radical prostatectomy (MIRP). METHODS: Retrospective review of 2006-2010 TRICARE data identified men diagnosed with prostate cancer (ICD-9 185) receiving open radical prostatectomy (ORP; ICD-9: 60.5) or MIRP (ICD-9 60.5 + 54.21/17.42). Patients diagnosed at military facilities but underwent surgery at civilian facilities were defined as "transferring care". Logistic regression models identified predictors of transferring care for patients diagnosed at military facilities. A secondary analysis identified the predictors of MIRP receipt at civilian facilities. RESULTS: Of 1420 patients, 247 (17.4%) transferred care. These patients were more likely to undergo MIRP (OR = 7.83, p < 0.01), and get diagnosed at low-volume military facilities (OR = 6.10, p < 0.01). Our secondary analysis demonstrated that transferring care was strongly associated with undergoing MIRP (OR = 1.51, p = 0.04). CONCLUSIONS: Patient preferences induced a demand for greater utilization of MIRP and civilian facilities. Further work exploring factors driving these preferences and interventions tailoring them, based on evidence and cost considerations, is required.

Outcomes of Robotic versus Laparoscopic Partial Nephrectomy: an Updated Meta-Analysis of 4,919 Patients.

PURPOSE: We evaluated the current literature comparing outcomes of robotic vs laparoscopic partial nephrectomy. MATERIALS AND METHODS: We performed a literature search according to Cochrane guidelines up to December 2015 including studies comparing robotic and laparoscopic partial nephrectomy, and we compared baseline patient and tumor characteristics. We performed a meta-analysis to evaluate safety, effectiveness and functional outcomes of robotic vs laparoscopic partial nephrectomy using weighted mean difference and inverse variance pooled risk ratios, respectively. RESULTS: A total of 4,919 patients were included from 25 studies (robotic partial nephrectomy 2,681, laparoscopic partial nephrectomy 2,238). There were no significant differences between the 2 groups in terms of age, gender, laterality and final malignant pathology. Patients treated with robotic partial nephrectomy had larger tumors (WMD 0.17 cm, p=0.001) and higher mean R.E.N.A.L. nephrometry scores (WMD 0.59, p=0.002), and were associated with a decreased likelihood of conversion to laparoscopic/open surgery compared to laparoscopic partial nephrectomy (RR 0.36, p <0.001), any (Clavien 1 or greater) (RR 0.84, p=0.007) and major (Clavien 3 or greater) (RR 0.71, p=0.023) complications, positive margins (RR 0.53, p <0.001) and shorter warm ischemia time by 4.3 minutes (p <0.001). Both approaches had similar operative times (WMD -12.2 minutes, p=0.34), estimated blood loss (WMD -24.6 ml, p=0.15) and postoperative change in estimated glomerular filtration rate. CONCLUSIONS: This updated meta-analysis of retrospective cohort studies demonstrated that robotic partial nephrectomy confers a superior morbidity profile compared to laparoscopic partial nephrectomy in most of the examined perioperative outcomes. Despite being the strongest available evidence (Level 2b) for outcomes of robotic vs laparoscopic partial nephrectomy thus far, there have been no completed or ongoing randomized trials to lend Level 1 support for either approach.

Surgeon and Hospital Level Variation in the Costs of Robot-Assisted Radical Prostatectomy.

PURPOSE: We assessed surgeon and hospital level variation in robot-assisted radical prostatectomy costs and predictors of high and low cost surgery. MATERIALS AND METHODS: The study population consisted of a weighted sample of 291,015 men who underwent robot-assisted radical prostatectomy for prostate cancer by 667 surgeons at 197 U.S. hospitals from 2003 to 2013. We evaluated 90-day direct hospital costs (2014 USD) in the Premier Hospital Database. High costs per robot-assisted radical prostatectomy were those above the 90th percentile and low costs were those below the 10th percentile. RESULTS: Mean hospital cost per robot-assisted radical prostatectomy was $11,878 (95% CI $11,804-$11,952). Mean cost was $2,837 (95% CI $2,805-$2,869) in the low cost group vs $25,906 (95% CI $24,702-$25,490) in the high cost group. Nearly a third of the variation in robot-assisted radical prostatectomy cost was attributable to hospital characteristics and more than a fifth was attributable to surgeon characteristics (R-squared 30.43% and 21.25%, respectively). High volume surgeons and hospitals (90th percentile or greater) had decreased odds of high cost surgery (surgeons: OR 0.24, 95% CI 0.11-0.54; hospitals: OR 0.105, 95% CI 0.02-0.46). The performance of robot-assisted radical prostatectomy at a high volume hospital was associated with increased odds of low cost robot-assisted radical prostatectomy (OR 839, 95% CI 122-greater than 999). CONCLUSIONS: This study provides insight into the role of surgeons and hospitals in robot-assisted radical prostatectomy costs. Given the substantial variability, identifying and remedying the root cause of outlier costs may yield substantial benefits.

Trends in utilisation, perioperative outcomes, and costs of nephroureterectomies in the management of upper tract urothelial carcinoma: a 10-year population-based analysis.

OBJECTIVE: To perform a population-based study to evaluate contemporary utilisation trends, morbidity, and costs associated with nephroureterectomies (NUs), as contemporary data for NUs are largely derived from single academic institution series describing the experience of high-volume surgeons and it is unclear if the same favourable results occur at a national level. PATIENTS AND METHODS: Using the Premier Hospital Database, we captured patients undergoing a NU with diagnoses of renal pelvis or ureteric neoplasms from 2004 to 2013. We fitted regression models, adjusting for clustering by hospitals and survey weighting to evaluate 90-day postoperative complications, operating-room time (OT), prolonged length of stay (pLOS), and direct hospital costs among open (ONU), laparoscopic (LNU) and robotic (RNU) approaches. RESULTS: After applying sampling and propensity weights, we derived a final study cohort of 17 254 ONUs, 13 317 LNUs and 3774 RNUs for upper tract urothelial carcinoma (UTUC) in the USA between 2004 and 2013. During that period, minimally invasive NU (miNU) increased from 36% to 54%, while the total number of NUs decreased by nearly 20%. No differences were noted in perioperative outcomes between the three surgical approaches, including when the analysis was restricted to the highest-volume hospitals and highest-volume surgeons. The OT was longer for LNU and RNU (P < 0.001), while the pLOS rates were decreased (P < 0.001). Adjusted 90-day median direct hospital costs were higher for LNU and RNU (P < 0.001), which disappeared when adjusting for the highest-volume groups, except for RNUs performed by high-volume surgeons. CONCLUSIONS: During this contemporary 10-year study, miNU has been replacing ONU for UTUC with a recent surge in RNU, along with a concurrent reduction in total NUs performed. Despite not being associated with a clinically significant improvement in perioperative outcomes, the costs for miNUs were consistently higher. However, higher hospital volumes suggest a potential cost containment strategy when performing miNUs.
