Telemedicine for Multidisciplinary Urologic Cancer Care: A Prospective Single Institution Study.

BACKGROUND: We rapidly implemented a telemedicine Multidisciplinary Urologic Cancer Clinic (MDUCC) at the University of Washington/Seattle Cancer Care Alliance during the peak of the COVID-19 Public Health Emergency to maintain our ability to provide multidisciplinary cancer care. We report our experiences though assessment of patient-reported outcomes from our telemedicine MDUCC. METHODS: Video visits with a urologic oncologist, medical oncologist, and radiation oncologist were conducted in the same format as our in-person MDUCC. We prospectively collected patient demographic and clinical data. Patients were invited to complete a post-visit survey that assessed satisfaction, provider trust, travel time, and costs of the telemedicine visit. We estimated travel distances and times from each patient's home to our clinic. RESULTS: Among invited patients, twenty-four patients completed a survey after their telemedicine MDUCC visit. Twenty patients (83%) were at home during the visit. Most (85%) were men, Caucasian (79%), and were being seen in our Bladder Cancer MDUCC (83%). All twenty-four patients responded that they would be willing to have future appointments via telemedicine; eighteen patients (75%) strongly agreed that the encounter was high quality; 19 patients strongly agreed that they were satisfied with their visit. Patients saved an estimated average one-way travel distance of 145 miles and one-way travel time of 179 minutes to convene a telemedicine visit. CONCLUSIONS: Telemedicine MDUCCs are feasible and effective in providing access to multidisciplinary urologic cancer care. Patient satisfaction was high, and many patients were spared a substantial travel burden. Telemedicine may continue to be leveraged to improve access to multidisciplinary urologic cancer care.

Interstate Telemedicine for Urologic Cancer Care.

PURPOSE: US states eased licensing restrictions on telemedicine during the COVID-19 pandemic, allowing interstate use. As waivers expire, optimal uses of telemedicine must be assessed to inform policy, legislation, and clinical care. We assessed whether telemedicine visits provided the same patient experience as in-person visits, stratified by in- vs out-of-state residence, and examined the financial burden. MATERIALS AND METHODS: Patients seen in person and via telemedicine for urologic cancer care at a major regional cancer center received a survey after their first appointment (August 2019-June 2022) on satisfaction with care, perceptions of communication during their visit, travel time, travel costs, and days of work missed. RESULTS: Surveys were completed for 1058 patient visits (N = 178 in-person, N = 880 telemedicine). Satisfaction rates were high for all visit types, both interstate and in-state care (mean score 60.1-60.8 [maximum 63], P > .05). More patients convening interstate telemedicine would repeat that modality (71%) than interstate in-person care (61%) or in-state telemedicine (57%). Patients receiving interstate care had significantly higher travel costs (median estimated visit costs $200, IQR $0-$800 vs median $0, IQR $0-$20 for in-state care, P < .001); 55% of patients receiving interstate in-person care required plane travel and 60% required a hotel stay. CONCLUSIONS: Telemedicine appointments may increase access for rural-residing patients with cancer. Satisfaction outcomes among patients with urologic cancer receiving interstate care were similar to those of patients cared for in state; costs were markedly lower. Extending interstate exemptions beyond COVID-19 licensing waivers would permit continued delivery of high-quality urologic cancer care to rural-residing patients.

Patient-centered outcomes of telehealth for the care of rural-residing patients with urologic cancer.

BACKGROUND: Patients residing in rural areas with urologic cancers confront significant obstacles in obtaining oncologic care. In the Pacific Northwest, a sizeable portion of the population lives in a rural county. Telehealth offers a potential access solution. METHODS: Patients receiving urologic care through telehealth or an in-person appointment at the Fred Hutchinson Cancer Center in Seattle, Washington, were surveyed to assess appointment-related satisfaction and travel costs. Patients' residences were classified as rural or urban based on their self-reported ZIP code. Median patient satisfaction scores and appointment-related travel costs were compared by rural versus urban residence within telehealth and in-person appointment groups using Wilcoxon signed-rank or χ2 testing. RESULTS: A total of 1091 patients seen for urologic cancer care between June 2019 and April 2022 were included, 28.7% of which resided in a rural county. Patients were mostly non-Hispanic White (75%) and covered by Medicare (58%). Among rural-residing patients, telehealth and in-person appointment groups had the same median satisfaction score (61; interquartile ratio, 58, 63). More rural-residing than urban-residing patients in the telehealth appointment groups strongly agreed that "Considering the cost and time commitment of my appointment, I would choose to meet with my provider in this setting in the future" (67% vs. 58%, p = .03). Rural-residing patients with in-person appointments carried a higher financial burden than those with telehealth appointments (medians, $80 vs. $0; p <.001). CONCLUSIONS: Appointment-related costs are high among rural-residing patients traveling for urologic oncologic care. Telehealth provides an affordable solution that does not compromise patient satisfaction.

Blood and urine biomarkers in prostate cancer: Are we ready for reflex testing in men with an elevated prostate-specific antigen?

OBJECTIVE: There is no consensus on the role of biomarkers in determining the utility of prostate biopsy in men with elevated prostate-specific antigen (PSA). There are numerous biomarkers such as prostate health index, 4Kscore, prostate cancer antigen 3, ExoDX, SelectMDx, and Mi-Prostate Score that may be useful in this decision-making process. However, it is unclear whether any of these tests are accurate and cost-effective enough to warrant being a widespread reflex test following an elevated PSA. Our goal was to report on the clinical utility of these blood and urine biomarkers in prostate cancer screening. METHODS: We performed a systematic review of studies published between January 2000 and October 2020 to report the available parameters and cost-effectiveness of the aforementioned diagnostic tests. We focus on the negative predictive value, the area under the curve, and the decision curve analysis in comparing reflexive tests due to their relevance in evaluating diagnostic screening tests. RESULTS: Overall, the biomarkers are roughly equivalent in predictive accuracy. Each test has additional clinical utility to the current diagnostic standard of care, but the added benefit is not substantial to justify using the test reflexively after an elevated PSA. CONCLUSIONS: Our findings suggest these biomarkers should not be used in binary fashion and should be understood in the context of pre-existing risk predictors, patient's ethnicity, cost of the test, patient life-expectancy, and patient goals. There are more recent diagnostic tools such as multi-parametric magnetic resonance imaging, polygenic single-nucleotide panels, IsoPSA, and miR Sentinel tests that are promising in the realm of prostate cancer screening and need to be investigated further to be considered a consensus reflexive test in the setting of prostate cancer screening.

Interprofessional Consultations (eConsults) in Urology.

INTRODUCTION: An interprofessional consultation (eConsult) is an asynchronous form of telehealth whereby a primary care provider requests electronic consultation with a specialist in place of an in-person consultation. While eConsults have been successfully implemented in many medical specialties, their use in the practice of urology is relatively unknown. METHODS: We included data from four academic institutions: University of Michigan, University of California -San Francisco, University of Washington, and Montefiore Medical Center. We included every urological eConsult performed at each institution from the launch of their respective programs through August 2019. We considered an eConsult "converted" when the participating urologist recommended a full in-person evaluation. We report eConsult conversion rate, response time, completion time, and diagnosis categories. RESULTS: A total of 462 urological eConsults were requested. Of these, 36% were converted to a traditional in-person visit. Among resolved eConsults, with data on provider response time available (n=119),53.8% of eConsults were addressed in less than 1 day; 28.6% in 1 day; 8.4% in 2 days; 3.4% in 3 days; 3.4% in 4 days; 1.7% in 5 days; and 0.8% in ≥6 days. Among resolved eConsults, with data on provider completion time available (n=283), 50.2% were completed in 1-10 minutes; 46.7% in 11-20 minutes; 2.8% in 21-30 minutes; and less than 1% in ≥31 minutes. DISCUSSION: Our study suggests that eConsults are an effective avenue for urologists to provide recommendations for many common non-surgical urological conditions and thus avoid a traditional in-person for low-complexity situations. Further investigation into the impact of eConsults on healthcare costs and access to urological care are necessary.

Clinical Utility of 4Kscore®, ExosomeDx™ and Magnetic Resonance Imaging for the Early Detection of High Grade Prostate Cancer.

PURPOSE: We aimed to evaluate 4Kscore® and ExosomeDx™ with multiparametric magnetic resonance imaging in the detection of high grade prostate cancer and number of biopsies avoided. MATERIAL AND METHODS: Patients had 1 liquid biomarker test with or without multiparametric magnetic resonance imaging. High grade prostate cancer was defined as Gleason grade group 2 or greater. The overall number of avoided biopsies (with Gleason grade 1 or less), and number of missed Gleason grade 2 or greater cancer among the biopsied patients, were determined. RESULTS: Of the 783 patients in the overall cohort 419 (53.5%) underwent biopsy. 4Kscore and ExosomeDx scores higher than the manufacturers' cut point were associated with PI-RADS™ scores 3 to 5 and Gleason grade 2 or greater prostate cancer. Limiting biopsy to the men with liquid biomarker scores above the manufacturers' cut point would have resulted avoiding 29.5% to 39.9% unnecessary biopsies overall, while missing 4.0% to 4.8% Gleason grade 2 or greater prostate cancer in the biopsy group. Screening algorithms with up-front liquid biomarker testing followed by multiparametric magnetic resonance imaging if the biomarker is above the manufacturers' cut point, then followed by biopsy if the multiparametric magnetic resonance imaging is positive or if 4Kscore 20 or greater or ExosomeDx 19 or greater would have missed 4.8% to 5.6% of Gleason grade 2 or greater prostate cancer in the biopsy group while avoiding 39.4% to 43.0% biopsies and 29.5% to 39.9% multiparametric magnetic resonance imaging overall. Similar algorithms with up-front multiparametric magnetic resonance imaging followed by liquid biomarker testing for negative multiparametric magnetic resonance imaging would have missed 2.4% of Gleason grade 2 or greater prostate cancer in the biopsy group but only avoided 17.2% 19.3% biopsies overall. CONCLUSIONS: Screening algorithms with up-front liquid biomarker testing followed by multiparametric magnetic resonance imaging and biopsy at certain biomarker thresholds could reduce unnecessary biopsies, multiparametric magnetic resonance imaging and overdetection of Gleason grade 1 prostate cancer.

Risk stratification metrics for bladder cancer: Comprehensive Geriatric Assessments.

Despite advances in surgical technique and perioperative care pathways, complication rates following radical cystectomy for bladder cancer remain high and perioperative outcomes for elderly patients are suboptimal. Furthermore, subjective risk assessments of patients with bladder cancer, with a high prevalence of complex comorbidity burden and risk of frailty, may result in undertreatment of patients assumed to be poor operative candidates. A critical component of preoperative patient counseling and treatment selection is accurate and objective preoperative risk appraisal. Comprehensive Geriatric Assessments are multi-domain evaluations of the medical, functional, and psychosocial aspects of health designed specifically for use in elderly patients with the objective of identifying vulnerabilities that may be targeted with interventions for improvement. While currently recommended by multiple guideline bodies for use in the preoperative evaluation of elderly patients with bladder cancer there is a paucity of data describing their use in contemporary clinical practice. Herein, then, we will describe the components of a Comprehensive Geriatric Assessments and propose strategies for their integration into the preoperative surgical workflow.

Genomic Risk Predicts Molecular Imaging-detected Metastatic Nodal Disease in Prostate Cancer.

BACKGROUND: The Decipher genomic classifier (GC) is increasingly being used to determine metastasis risk in men with localized prostate cancer (PCa). Whether GCs predict for the presence of occult metastatic disease at presentation or subsequent metastatic progression is unknown. OBJECTIVE: To determine if GC scores predict extraprostatic 68Ga prostate-specific membrane antigen (68Ga-PSMA-11) positron emission tomography (PET) positivity at presentation. DESIGN, SETTING, AND PARTICIPANTS: Between December 2015 and September 2018, 91 PCa patients with both GC scores and pretreatment 68Ga-PSMA-11 PET scans were identified. Risk stratification was performed using the National Comprehensive Cancer Network (NCCN), Cancer of the Prostate Risk Assessment (CAPRA), and GC scores. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Logistic regression was used to identify factors correlated with PSMA-positive disease. RESULTS AND LIMITATIONS: The NCCN criteria identified 23 (25.3%) and 68 patients (74.7%) as intermediate and high risk, while CAPRA scores revealed 28 (30.8%) and 63 (69.2%) as low/intermediate and high risk, respectively. By contrast, only 45 patients (49.4%) had high-risk GC scores. PSMA-avid pelvic nodal involvement was identified in 27 patients (29.7%). Higher GC score was significantly associated with pelvic nodal involvement (odds ratio [OR] 1.38 per 0.1 units; p=0.009) and any PSMA-avid nodal involvement (pelvic or distant; OR 1.40 per 0.1 units; p=0.007). However, higher GC score was not significantly associated with PSMA-avid osseous metastases (OR 1.11 per 0.1 units; p=0.50). Limitations include selection bias for patients able to receive both tests and the sample size. CONCLUSIONS: Each 0.1-unit increase in GC score was associated with an approximate 40% increase in the odds of PSMA-avid lymph node involvement. These data suggest that patients with GC high risk might benefit from more nodal imaging and treatment intensification, potentially via pelvic nodal dissection, pelvic nodal irradiation, and/or the addition of chemohormonal agents. PATIENT SUMMARY: Patients with higher genomic classifier scores were found to have more metastatic lymph node involvement on prostate-specific membrane antigen imaging.

Location of Recurrence by Gallium-68 PSMA-11 PET Scan in Prostate Cancer Patients Eligible for Salvage Radiotherapy.

OBJECTIVE: To identify locations of recurrence after radical prostatectomy (RP) with prostate-specific antigen (PSA) <2 by Gallium-68 prostate-specific membrane antigen (PSMA)-11 Positron Emission Tomography (PET) imaging, and to determine whether standard nodal radiation fields would cover the location of prostate cancer recurrence. MATERIALS AND METHODS: We performed a retrospective review of patients with PSMA-PET imaging for biochemical recurrence following RP with PSA ≤2.0 ng/mL and assessed if the recurrent disease was within standard radiation target volumes. We compared patient and clinical variables between men with recurrences covered by standard salvage radiation fields and those with recurrences outside of standard fields. RESULTS: We identified 125 patients for study inclusion. The median PSA at imaging was 0.40 ng/mL (interquartile range 0.28-0.63). PSMA-avid disease was found in 66 patients (53%). Of these, 25 patients (38%) had PSMA-avid lesions found outside of the pelvis, 33 (50%) had lesions confined to the pelvic lymph nodes and prostate bed, and 8 (12%) men had PSMA-avid recurrence only in the prostate bed. Salvage radiation including standard Intensity Modulated Radiation Therapy (IMRT) pelvic nodal volumes would not cover PSMA-avid nodal disease in 38 men (30%). PSA at the time of imaging was statistically associated with having PSMA-avid disease outside of standard nodal fields (P <.01). CONCLUSION: The 68Ga-PSMA-11 PET detects disease in a majority of patients with PSA ≤2.0 following RP. Nearly one-third of men had PSMA-avid disease that would be missed by standard radiation fields. This imaging modality may dramatically impact the design and use of post-RP salvage radiotherapy.

Prostate Cancer Markers.

Diagnostic biomarkers derived from blood, urine, or prostate tissue provide additional information beyond clinical calculators to determine the risk of detecting high-grade prostate cancer. Once diagnosed, multiple markers leverage prostate cancer biopsy tissue to prognosticate clinical outcomes, including adverse pathology at radical prostatectomy, disease recurrence, and prostate cancer mortality; however the clinical utility of some outcomes to patient decision making is unclear. Markers using tissue from radical prostatectomy specimens provide additional information about the risk of biochemical recurrence, development of metastatic disease, and subsequent mortality beyond existing multivariable clinical calculators (the use of a marker to simply sub-stratify risk groups such as the NCCN groups is of minimal value). No biomarkers currently available for prostate cancer have been prospectively validated to be predict an improved clinical outcome for a specific therapy based on the test result; however, further research and development of these tests may produce a truly predictive biomarker for prostate cancer treatment.

Effect of Oscillation on Perineal Pressure in Cyclists: Implications for Micro-Trauma.

BACKGROUND: Genital numbness and erectile dysfunction in cyclists may result from repeated perineal impacts on the bicycle saddle (micro-trauma) that occur during routine cycling. AIM: To evaluate the relationship between oscillation forces and perineal pressures among cyclists in a simulated laboratory setting. METHODS: Participants were fit to a study bicycle to ensure all cyclists had the same torso angle (60 ± 1 degree) and maximum knee angle (150 ± 1 degree). A lever system was used to generate oscillation events of 3 progressively increasing magnitudes. Perineal pressure was continuously measured using a pressure sensor on the bicycle saddle. This process was carried out in each of the following conditions: (1) stationary (not pedaling) with the standard seatpost, (2) pedaling with standard seatpost, (3) stationary with seatpost shock absorber, and (4) pedaling with seatpost shock absorber. OUTCOMES: We compared perineal pressure changes during oscillation events in the stationary and pedaling states, with and without the seatpost shock absorber. RESULTS: A total of 39 individuals were recruited (29 men and 10 women). As the amount of oscillation increased from an average of 0.7g (acceleration due to Earth's gravity) to 1.3g, the perineal pressure increased from 10.3% over baseline to 19.4% over baseline. There was a strong linear relationship between the amount of oscillation and increase in pressure (r2 = 0.8, P < .001). A seatpost shock absorber decreased the impact of oscillation by 53% in the stationary condition. Men and women absorbed the majority of shock in areas corresponding to pelvic bony landmarks. CONCLUSION: This study represents one of the first characterizations of cycling-associated perineal micro-trauma in a laboratory setting. We found a strong linear relationship between oscillation magnitude and perineal pressure during cycling, which was mitigated by a seatpost shock absorber. The use of shock absorption in bicycle design may reduce perineal micro-trauma and potentially improve cycling-associated perineal numbness and erectile dysfunction.

Measuring quality of urology care using a qualified clinical data registry.

PURPOSE OF REVIEW: Qualified clinical data registries (QCDRs) serve as a framework for quality improvement efforts, clinical research endeavors, and participation in reimbursement incentive programs. However, the measurement of quality and the recommendations to guide QCDRs in developing new quality measures is a complex process. In this review, we highlight the government policies that lead to the creation of QCDRs, how QCDR quality measures are developed, and the current QCDRs that focus on urological care. RECENT FINDINGS: QCDRs facilitate participation in the merit-based incentive payment system for reimbursement adjustments. Most QCDRs leverage existing clinical guidelines in the development of new quality measures. In 2018, there are four urology QCDRs with quality measures for many urological conditions. These QCDRs form the infrastructure for quality improvement and provide new resources for research endeavors. SUMMARY: Quality measurement within QCDRs will allow urologists to focus improvement efforts to deliver high-quality urological care while also facilitating reimbursement incentives and creating novel research datasets.

A novel urethral sparing technique for high-dose-rate prostate brachytherapy after transurethral resection of the prostate.

PURPOSE: The purpose of this study was to assess retrospectively the variability of the urethral dose optimized using a Foley catheter versus urethral contrast injected using a new modified triple-lumen catheter, in CT-based high-dose-rate (HDR) prostate brachytherapy of posttransurethral resection of prostate (TURP) patients. METHODS AND MATERIALS: At our institution, there were six post-TURP patients with prostate carcinoma between July 2014 and April 2016 who underwent transperineal interstitial HDR brachytherapy (16 needles). A custom modified triple-lumen catheter was placed to inject contrast into the TURP defect. Three-dimensional optimal plans using inverse planning simulated annealing algorithm was generated according to radiation therapy oncology group dose requirements. Alternative plans were retroactively generated for comparison using standard technique based on a Foley catheter as a urethral constraint volume for each patient with the same weighting factors. We compared the dosimetry parameters in each planning using Wilcoxon's ranked sum nonparametric test. RESULTS: The median followup of all patients was 17.5 months. No significant genitourinary or gastrointestinal toxicity was noted using this technique. In the dosimetric analysis, the prostate V100 values and TURP urethral V100 were significantly different between plans with and without the contrast (V100 [mean]: 92.4 [%] vs. 94.4 [%], p = 0.046; TURP UV100 [mean]: 1.4 cc vs. 2.2 cc, p = 0.028). There were no statistical differences in the mean values of planning target volume V150%, V200%, and D90, and each bladder V75 and rectum V75. CONCLUSIONS: Post-TURP HDR brachytherapy with urethral contrast showed significantly more volume effect of the TURP defect than that with a Foley catheter alone. Better visualization of the TURP defect should lead to more accurate urethral sparing administration of HDR brachytherapy which is necessary to prevent urethral complication.

Predictors of Delayed Intervention for Patients on Active Surveillance for Small Renal Masses: Does Renal Mass Biopsy Influence Our Decision?

OBJECTIVE: To review our clinical T1a renal mass active surveillance (AS) cohort to determine whether renal mass biopsy was associated with maintenance of AS. MATERIALS AND METHODS: From our prospectively maintained database we identified patients starting AS from June 2009 to December 2011 who had at least 5 months of radiologic follow-up, unless limited by unexpected death or delayed intervention. The primary outcome was delayed intervention. Clinical, radiologic, and pathologic variables were compared. We constructed Kaplan-Meier survival curves for maintenance of AS. Cox multivariable regression analysis was performed to assess predictors of delayed intervention. RESULTS: We identified 118 patients who met criteria for inclusion with a median radiologic follow-up of 29.5 months. The delayed intervention group had greater initial mass size and faster growth rate compared to those who continued AS. Rate of renal mass biopsy was similar between the 2 groups. In the multivariable analysis, size >2 cm (hazard ratio [HR] 3.65, 95% confidence interval [CI] 1.28-10.38, P = .015), growth rate (continuous by mm/year: HR 1.26, 95% CI 1.12-1.41, P < .001), but not renal biopsy (HR 1.52, 95% CI 0.70-3.30, P = .29), were associated with increased risk of delayed intervention. Time-to-event curves also showed that size was closely associated with delayed intervention whereas renal mass biopsy was not. CONCLUSION: At our institution, growth rate and initial tumor size appear to be more influential than renal mass biopsy results in determining delayed intervention after a period of AS. Further analysis is required to determine the role of renal biopsy in the management of patients being considered for AS.
