Predicting risk of multiple levels of recurrence and progression after initial diagnosis of nonmuscle-invasive bladder cancer in a multisite, community-based cohort.

BACKGROUND: Nonmuscle-invasive bladder cancer (NMIBC) has heterogeneous recurrence and progression outcomes. Available risk calculators estimate recurrence and progression but do not predict the recurrence stage or grade, which may influence downstream treatment. The objective of this study was to predict risk-stratified NMIBC recurrence and progression based on recurrence tumor classification and grade. METHODS: In total, 2956 patients with NMIBC (

Cost-effectiveness of surveillance schedules in older adults with non-muscle-invasive bladder cancer.

OBJECTIVE: To estimate the cost-effectiveness of surveillance schedules for non-muscle-invasive bladder cancer (NMIBC) amongst older adults. PATIENTS AND METHODS: We developed a MIcrosimulation SCreening ANalysis (MISCAN) microsimulation model to compare the cost-effectiveness of various surveillance schedules (every 3 months to every 24 months, for 2, 5 or 10 years or lifetime) for older adults (aged 65-85 years) with NMIBC. For each surveillance schedule we calculated total costs per patient and the number of quality adjusted life-years (QALYs) gained. Incremental cost-effectiveness ratios (ICERs), as incremental costs per QALY gained, were calculated using a 3% discount. RESULTS: As age increased, the number of QALYs gained per patient decreased substantially. Surveillance of patients aged 65 years resulted in 2-7 QALYs gained, whereas surveillance at age 85 years led to <1 QALY gained. The total costs of the surveillance schedules also decreased as age increased. The ICER of 6-monthly surveillance at age 65 years for lifetime was $4999 (American dollars)/QALY gained. Amongst patients aged >75 years, the incremental yield of QALY gains for any increase in surveillance frequency and/or duration was quite modest (<2 QALYs gained). CONCLUSION: With increasing age, surveillance for recurrences leads to substantially fewer QALYs gained. These data support age-specific surveillance recommendations for patients treated for NMIBC.

Association between treatment of superficial bladder cancer and 10-year mortality in older adults with multiple chronic conditions.

BACKGROUND: Multiple chronic conditions (MCC) are common among older patients with cancer; however, the exclusion of these patients from clinical trials has resulted in scarce knowledge concerning outcomes, resulting in variations in treatment. Superficial bladder cancer (SBC) disproportionately affects older adults, yet to the authors' knowledge few studies to date have examined whether treatment improves long-term survival. In the current study, the authors evaluated the association between treatment of SBC and 10-year mortality in medically complex older adults. METHODS: The authors identified 1800 older (aged ≥60 years) patients with SBC (American Joint Committee on Cancer stage ≤I) from 2 community-based health systems who received treatment (bladder instillation and/or transurethral resection) or observation. Cox proportional hazards regression was performed adjusting for age, sex, race, health system, stage of disease/grade, and MCC (≥2 baseline chronic conditions). Propensity score analysis using stabilized inverse probability of treatment weights was used to compare 10-year mortality in the 2 treatment groups with adjustment for covariates. RESULTS: Overall, 1485 patients (82.5%) and 315 patients (17.5%) received treatment and observation, respectively. In unweighted multivariable analysis, treatment was associated with a 30% reduction in death (adjusted hazard ratio [HR], 0.70; 95% confidence interval [95% CI], 0.58-0.85 [P<.01]) and MCC with a 72% increase in death (adjusted HR, 1.72; 95% CI, 1.44-2.05 [P<.01]). Weighted analysis with adjustment (doubly robust) also demonstrated a survival benefit for treatment (adjusted HR, 0.66; 95% CI, 0.52-0.84 [P<.01]). CONCLUSIONS: The results of the current study demonstrated a clinically meaningful association between cancer treatment and survival benefit in older, medically complex patients with SBC, even after adjustment for medical complexity. These data provide a foundation for future work aimed at personalizing the treatment guidance of older patients with cancer with MCC.

Early cancer diagnoses through BRCA1/2 screening of unselected adult biobank participants.

PurposeThe clinical utility of screening unselected individuals for pathogenic BRCA1/2 variants has not been established. Data on cancer risk management behaviors and diagnoses of BRCA1/2-associated cancers can help inform assessments of clinical utility.MethodsWhole-exome sequences of participants in the MyCode Community Health Initiative were reviewed for pathogenic/likely pathogenic BRCA1/2 variants. Clinically confirmed variants were disclosed to patient-participants and their clinicians. We queried patient-participants' electronic health records for BRCA1/2-associated cancer diagnoses and risk management that occurred within 12 months after results disclosure, and calculated the percentage of patient-participants of eligible age who had begun risk management.ResultsThirty-seven MyCode patient-participants were unaware of their pathogenic/likely pathogenic BRCA1/2 variant, had not had a BRCA1/2-associated cancer, and had 12 months of follow-up. Of the 33 who were of an age to begin BRCA1/2-associated risk management, 26 (79%) had performed at least one such procedure. Three were diagnosed with an early-stage, BRCA1/2-associated cancer-including a stage 1C fallopian tube cancer-via these procedures.ConclusionScreening for pathogenic BRCA1/2 variants among unselected individuals can lead to occult cancer detection shortly after disclosure. Comprehensive outcomes data generated within our learning healthcare system will aid in determining whether population-wide BRCA1/2 genomic screening programs offer clinical utility.

Burden of Multiple Chronic Conditions among Patients with Urological Cancer.

PURPOSE: We describe age, multiple chronic condition profiles and health system contact in patients with urological cancer. MATERIALS AND METHODS: Using Geisinger Health System electronic health records we identified adult primary care patients and a subset with at least 1 urology encounter between 2001 and 2015. The Agency for Health Care Research and Quality Chronic Condition Indicator and Clinical Classifications Software tools were applied to ICD-9 codes to identify chronic conditions. Multiple chronic conditions were defined as 2 or more chronic conditions. Patients with urological cancer were identified using ICD-9 codes for prostate, bladder, kidney, testis and penile cancer. Inpatient and outpatient visits in the year prior to the most recent encounter were counted to document health system contact. RESULTS: We identified 357,100 primary care and 33,079 urology patients, of whom 4,023 had urological cancer. Patients with urological cancer were older than primary care patients (71 vs 46 years) and they had more median chronic conditions (7 vs 4). Kidney and bladder cancer were the most common chronic conditions (median 8 patients each). Coronary artery disease and chronic kidney disease were common in urological cancer cases compared to mental health conditions in primary care cases. Patients with urological cancer who had multiple chronic conditions had the most health system contact, including 32% with at least 1 hospitalization and 68% with more than 5 outpatient visits during 1 year. CONCLUSIONS: Urology patients are older and more medically complex, especially those with urological cancer than primary care patients. These data may inform care redesign to reduce the treatment burden and improve care coordination in urological cancer cases.

The AGING Initiative experience: a call for sustained support for team science networks.

Team science, defined as collaborative research efforts that leverage the expertise of diverse disciplines, is recognised as a critical means to address complex healthcare challenges, but the practical implementation of team science can be difficult. Our objective is to describe the barriers, solutions and lessons learned from our team science experience as applied to the complex and growing challenge of multiple chronic conditions (MCC). MCC is the presence of two or more chronic conditions that have a collective adverse effect on health status, function or quality of life, and that require complex healthcare management, decision-making or coordination. Due to the increasing impact on the United States society, MCC research has been identified as a high priority research area by multiple federal agencies. In response to this need, two national research entities, the Healthcare Systems Research Network (HCSRN) and the Claude D. Pepper Older Americans Independence Centers (OAIC), formed the Advancing Geriatrics Infrastructure and Network Growth (AGING) Initiative to build nationwide capacity for MCC team science. This article describes the structure, lessons learned and initial outcomes of the AGING Initiative. We call for funding mechanisms to sustain infrastructures that have demonstrated success in fostering team science and innovation in translating findings to policy change necessary to solve complex problems in healthcare.

Gender disparities in hematuria evaluation and bladder cancer diagnosis: a population based analysis.

PURPOSE: Men are diagnosed with bladder cancer at 3 times the rate of women. However, women present with advanced disease and have poorer survival, suggesting delays in bladder cancer diagnosis. Hematuria is the presenting symptom in most cases. We assessed gender differences in hematuria evaluation in older adults with bladder cancer. MATERIALS AND METHODS: Using the SEER (Surveillance, Epidemiology and End Results) cancer registry linked with Medicare claims we identified Medicare beneficiaries 66 years old or older diagnosed with bladder cancer between 2000 and 2007 with a claim for hematuria in the year before diagnosis. We examined the impact of gender, and demographic and clinical factors on time from initial hematuria claim to urology visit and on time from initial hematuria claim to hematuria evaluation, including cystoscopy, upper urinary tract imaging and urine cytology. RESULTS: Of 35,646 patients with a hematuria claim in the year preceding bladder cancer diagnosis 97% had a urology visit claim. Mean time to urology visit was 27 days (range 0 to 377). Time to urology visit was longer for women than for men (adjusted HR 0.9, 95% CI 0.87-0.92). Women were more likely to undergo delayed (after greater than 30 days) hematuria evaluation (adjusted OR 1.13, 95% CI 1.07-1.21). CONCLUSIONS: We observed longer time to a urology visit for women than for men presenting with hematuria. These findings may explain stage differences in bladder cancer diagnosis and inform efforts to decrease gender disparities in bladder cancer stage and outcomes.

Preoperative serum albumin is associated with mortality and complications after radical cystectomy.

OBJECTIVE: To determine the association between preoperative serum albumin and mortality and postoperative complications after radical cystectomy (RC) and urinary diversion. PATIENTS AND METHODS: We conducted a retrospective review of 1097 RCs performed for the treatment of bladder cancer between 1992 and 2005. All data were entered prospectively into a hospital-based complications database. We used multivariable logistic regression to assess the association between preoperative serum albumin and complications and mortality ≤90 days of RC, while controlling for preoperative patient and disease characteristics. RESULTS: Low preoperative serum albumin was identified in 14% of the cohort. Preoperative serum albumin was a predictor of postoperative complications (adjusted odds ratio [OR] per unit increase in albumin: 0.61, 95% confidence interval [CI] 0.42-0.90) and 90-day mortality (OR 0.33, 95% CI 0.14-0.75) when controlling for sex, race, age-adjusted Charlson score, body mass index, prior history of abdominal surgery, clinical stage, and neoadjuvant chemotherapy. As serum albumin decreased, the risk of complications and mortality increased. CONCLUSIONS: In addition to age-adjusted Charlson score, low preoperative serum albumin is a significant predictor of complications and mortality after RC. Serum albumin testing can be used to identify individuals at high-risk of morbidity and mortality.

Immediate total parenteral nutrition after radical cystectomy and urinary diversion.

INTRODUCTION: The purpose of this study is to determine if administration of total parenteral nutrition (TPN) immediately following radical cystectomy and urinary diversion provides significant recovery benefit when compared to patients who did not receive TPN. METHODS: Retrospective chart review was performed on patients who underwent open radical cystectomy and urinary diversion from February 2002 to June 2010. Patients were divided into 2 cohorts-those who received immediate postoperative TPN and those who did not. Preoperative demographics, length of hospital stay, time until tolerating a regular diet and early postoperative complications of the 2 groups were extracted and compared. RESULTS: One hundred seventy-four patients (104 receiving TPN, 70 without TPN) were available for analysis. No significant difference in preoperative characteristics, length of hospital stay, estimated blood loss, or time until tolerating a general diet between the 2 groups was noted. With regard to complications, the incidence of bacteremia was significantly higher in the TPN vs non-TPN cohort (9% vs 1%, P < 0.05). CONCLUSION: Immediate administration of TPN following radical cystectomy and urinary diversion does not provide a significant postoperative benefit and may lead to an increased risk of bacteremia.

Geriatric assessment-derived deficit accumulation and patient-reported treatment burden in older adults with bladder cancer.

BACKGROUND: When a person's workload of healthcare exceeds their resources, they experience treatment burden. At the intersection of cancer and aging, little is known about treatment burden. We evaluated the association between a geriatric assessment-derived Deficit Accumulation Index (DAI) and patient-reported treatment burden in older adults with early-stage, non-muscle-invasive bladder cancer (NMIBC). METHODS: We conducted a cross-sectional survey of older adults with NMIBC (≥65 years). We calculated DAI using the Cancer and Aging Research Group's geriatric assessment and measured urinary symptoms using the Urogenital Distress Inventory-6 (UDI-6). The primary outcome was Treatment Burden Questionnaire (TBQ) score. A negative binomial regression with LASSO penalty was used to model TBQ. We further conducted qualitative thematic content analysis of responses to an open-ended survey question ("What has been your Greatest Challenge in managing medical care for your bladder cancer") and created a joint display with illustrative quotes by DAI category. RESULTS: Among 119 patients, mean age was 78.9 years (SD 7) of whom 56.3% were robust, 30.3% pre-frail, and 13.4% frail. In the multivariable model, DAI and UDI-6 were significantly associated with TBQ. Individuals with DAI above the median (>0.18) had TBQ scores 1.94 times greater than those below (adjusted IRR 1.94, 95% CI 1.33-2.82). Individuals with UDI-6 greater than the median (25) had TBQ scores 1.7 times greater than those below (adjusted IRR 1.70, 95% CI 1.16-2.49). The top 5 themes in the Greatest Challenge question responses were cancer treatments (22.2%), cancer worry (19.2%), urination bother (18.2%), self-management (18.2%), and appointment time (11.1%). CONCLUSIONS: DAI and worsening urinary symptoms were associated with higher treatment burden in older adults with NMIBC. These data highlight the need for a holistic approach that reconciles the burden from aging-related conditions with that resulting from cancer treatment.

Interruptions in bladder cancer care during the COVID-19 public health emergency.

BACKGROUND: Academic and community urology centers participating in a pragmatic clinical trial in non-muscle-invasive bladder cancer completed monthly surveys assessing restrictions in aspects of bladder cancer care due to the COVID-19 Public Health Emergency. Our objective was to describe pandemic-related restrictions on bladder cancer care. METHODS: We invited 32 sites participating in a multicenter pragmatic bladder cancer trial to complete monthly surveys distributed through REDCap beginning in May 2020. These surveys queried sites on whether they were experiencing restrictions in the use of elective surgery, transurethral resection of bladder tumors (TURBT), radical cystectomy, office cystoscopy, and intravesical bacillus Calmette-Guerin (BCG) availability. Responses were collated with descriptive statistics. RESULTS: Of 32 eligible sites, 21 sites had at least a 50% monthly response rate over the study period and were included in the analysis. Elective surgery was paused at 76% of sites in May 2020, 48% of sites in January 2021, and 52% of sites in January 2022. Over those same periods, coinciding with COVID-19 incidence waves, TURBT was restricted at 10%, 14%, and 14% of sites, respectively, radical cystectomy was restricted at 10%, 14%, and 19% of sites, respectively, and cystoscopy was restricted at 33%, 0%, and 10% of sites, respectively. CONCLUSIONS: Bladder cancer care was minimally restricted compared with more pronounced restrictions seen in general elective surgeries during the COVID-19 pandemic.

Urinary diversion practice patterns among certifying American urologists.

PURPOSE: We investigated trends in urinary diversion use and surgeon characteristics in the performance of incontinent and continent urinary diversion using American Board of Urology data. MATERIALS AND METHODS: Annualized case log data for urinary diversion were obtained from the American Board of Urology for urologists who certified or recertified from 2002 to 2010. We evaluated the association between surgeon characteristics and the performance of any urinary diversion or the type of urinary diversion. RESULTS: Of the 5,096 certifying or recertifying urologist case logs examined 1,868 (37%) urologists performed any urinary diversion. The median number of urinary diversions was 4 per year (IQR 2, 6) and 222 urologists (4%) performed 10 or more per year. On multivariate analysis younger urologists, those self-identified as oncologists or female urologists, those who certified in more recent years and those in larger practice areas or outside the Northeast region of the United States were more likely to perform any urinary diversion. Only 9% of the total cohort (471 urologists) performed any continent urinary diversion. The likelihood of performing any continent urinary diversion increased with the number of urinary diversions (p <0.0001). As urinary diversion volume increased, the proportion representing continent urinary diversion also increased (p <0.0005). Surgeons in private practice settings and those in the Northeast were less likely to perform continent urinary diversion. CONCLUSIONS: Few urologists perform any urinary diversion. Continent urinary diversion is most frequently done by high volume surgeons. The type of urinary diversion that a patient receives may depend in part on surgeon characteristics.

Performance Characteristics of a Rule-Based Electronic Health Record Algorithm to Identify Patients with Gross and Microscopic Hematuria.

BACKGROUND: Two million patients per year are referred to urologists for hematuria, or blood in the urine. The American Urological Association recently adopted a risk-stratified hematuria evaluation guideline to limit multi-phase computed tomography to individuals at highest risk of occult malignancy. OBJECTIVES: To understand population-level hematuria evaluations, we developed an algorithm to accurately identify hematuria cases from electronic health records (EHRs). METHODS: We used International Classification of Diseases (ICD)-9/ICD-10 diagnosis codes, urine color, and urine microscopy values to identify hematuria cases and to differentiate between gross and microscopic hematuria. Using an iterative process, we refined the ICD-9 algorithm on a gold standard, chart-reviewed cohort of 3,094 hematuria cases, and the ICD-10 algorithm on a 300 patient cohort. We applied the algorithm to Geisinger patients ≥35 years (n = 539,516) and determined performance by conducting chart review (n = 500). RESULTS: After applying the hematuria algorithm, we identified 51,500 hematuria cases and 488,016 clean controls. Of the hematuria cases, 11,435 were categorized as gross, 26,658 as microscopic, 12,562 as indeterminate, and 845 were uncategorized. The positive predictive value (PPV) of identifying hematuria cases using the algorithm was 100% and the negative predictive value (NPV) was 99%. The gross hematuria algorithm had a PPV of 100% and NPV of 99%. The microscopic hematuria algorithm had lower PPV of 78% and NPV of 100%. CONCLUSION: We developed an algorithm utilizing diagnosis codes and urine laboratory values to accurately identify hematuria and categorize as gross or microscopic in EHRs. Applying the algorithm will help researchers to understand patterns of care for this common condition.

Systematic classification and prediction of complications after nephrectomy in patients with metastatic renal cell carcinoma (RCC).

UNLABELLED: Study Type - Harm (case series) Level of Evidence 4. What's known on the subject? and What does the study add? Radical nephrectomy for patients with metastatic renal cell carcinoma results in greater rates of morbidity than for those with less advanced disease. This study systematically characterizes complications associated with nephrectomy for metastatic RCC and identifies patient and disease characteristics that are associated with a greater risk of developing complications. Overall complications were relatively frequent, but major complications (grade 3 or greater) were rare. Increasing age and worsening performance status were associated with increased probability of complications. When complications were sustained, patients were less likely to receive systemic therapy in a timely fashion. These observations may influence the timing or patient selection for surgery or systemic therapy. OBJECTIVE: • To evaluate and identify factors predictive for morbidity after radical nephrectomy in patients with metastatic renal cell carcinoma (mRCC). PATIENTS AND METHODS: • We identified patients with mRCC who underwent nephrectomy at Memorial Sloan-Kettering Cancer Center (MSKCC) between 1989 and 2009. • Postoperative complications were characterised using a modified version of the Clavien-Dindo classification system. • Patient and disease characteristics, including a previously validated MSKCC risk-stratification system using calcium, haemoglobin (Hb), lactate dehydrogenase, and Karnofsky Performance Status (KPS), were evaluated as predictors of postoperative complications using univariate and multivariable logistic regression models. • The area under the receiver operating characteristic curve (AUC) was calculated for each model to assess predictive accuracy and corrected for overfit using 10-fold cross validation. RESULTS: • Over the study period, 195 patients with mRCC underwent nephrectomy; 53 (27%) developed grade ≥ 2 complications within 8 weeks of surgery. • Pulmonary, thromboembolic events and anaemia requiring transfusion were the most common types of complications after nephrectomy in the metastatic setting. • In univariate analysis, age, low albumin, low KPS, high corrected serum calcium, low serum Hb, and unfavourable MSKCC risk score were predictive of complications. • Patients who sustained postoperative complications were less likely to receive systemic therapy within 56 days (odds ratio [OR] 0.32; 95% confidence interval [CI] 0.12-0.86; P= 0.024). • A multivariable model containing KPS (OR 14.5; 95%CI 4.34-48.6; P < 0.001) and age (OR 1.04; 95%CI 1.01-1.08; P= 0.014) showed the greatest predictive accuracy (corrected AUC 0.72; 95%CI 0.63-0.80) for postoperative complications. CONCLUSIONS: • Postoperative complications after radical nephrectomy in the setting of mRCC are common and occur frequently in older patients and those with worse KPS. • These complications are important because they may delay or deny receipt of subsequent systemic therapy.

Urologic oncology workforce diversity: A first step in reducing cancer disparities.

Urologic cancer disparities based on race/ethnicity and gender are well-documented across the cancer continuum. Patients cared for by physicians of similar race/ethnicity and gender report better communication, patient satisfaction, and care adherence which has the potential to translate into better health outcomes. We believe that ensuring a diverse Urologic Oncology workforce is an important first step toward eliminating cancer disparities due to the downstream effects of improved communication between concordant patient-physician dyads. In this essay, we review the demographics of the Urologic cancer patient population and Urologic Oncology workforce; describe current evidence supporting healthcare workforce diversity, especially related to race and gender-based concordant patient-physician relationships; and make recommendations for individual and institutional strategies to develop and support a diverse workforce in Urologic Oncology.

Demographic and Practice Trends of Rural Urologists in the U.S.: Implications for Workforce Policy.

INTRODUCTION: There is a shortage in the number of urologists needed to satisfy the needs of an aging U.S. POPULATION: The urologist shortage may have a pronounced impact on aging rural communities. Our objective was to describe the demographic trends and scope of practice of rural urologists using data from the American Urological Association Census. METHODS: We conducted a retrospective analysis of American Urological Association Census survey data over a 5-year period (2016-2020), including all U.S.-based practicing urologists. Metropolitan (urban) and nonmetropolitan (rural) practice classifications were based on rural-urban commuting area codes for the primary practice location zip code. We conducted descriptive statistics of demographics, practice characteristics and specific rural-focused survey items. RESULTS: In 2020, rural urologists were older (60.9 years, 95% CI 58.5-63.3 vs 54.6 years, 95% CI 54.0-55.1) and were in practice longer (25.4 years, 95% CI 23.2-27.5 vs 21.2 years, 95% CI 20.8-21.5) than urban counterparts. Since 2016, mean age and years in practice increased for rural urologists but remained stable for urban urologists, suggesting an influx of younger urologists to urban areas. Compared with urban urologists, rural urologists had significantly less fellowship training and more frequently worked in solo practice, multispecialty groups and private hospitals. CONCLUSIONS: The urological workforce shortage will particularly impact rural communities and their access to urological care. We hope our findings will inform and empower policymakers to develop targeted interventions to expand the rural urologist workforce.
