Impact of Socioeconomic Status on Patient Adherence in Managing Renal Masses.

INTRODUCTION: Previous literature suggests socioeconomic status and racial disparities impact management decisions for patients with small renal masses. We aim to build upon these findings and examine how these modalities impact patient adherence to their management plan. METHODS: This retrospective study analyzed our Kidney Tumor Program database (n = 1476) containing patients from 2000 to 2020. Socioeconomic status was estimated using 2 modalities: Area Deprivation Index and household income. Patients were then evaluated for differences in adherence, nonadherence, and loss to follow-up. Adherent patients completed all recommended appointments within 6 months of their initial follow-up. Nonadherent patients did not complete all recommended appointments within 6 months of their originally scheduled follow-up but eventually did. Patients lost to follow-up were recommended to follow up but never did. RESULTS: Patient adherence was not significantly different across sex or primary treatment method but differed with respect to race/ethnicity. Black patients were significantly more likely to be nonadherent (P = .021) and lost to follow-up (P = .008). After adjusting for race/ethnicity, Area Deprivation Index and income bracket were significantly associated with adherence and loss to follow-up. Patients with a high socioeconomic status had significantly higher rates of adherence (ADI, quartile [Q] 1 vs Q4, P = .038; income, >$120,000 vs $30,000-$59,999, P < .003) and decreased loss to follow-up (ADI, Q1 vs Q4, P = .03; income, >$120,000 vs $30,000-$59,999, P = .002). CONCLUSIONS: Our results demonstrate that Black race and low socioeconomic status are associated with decreased adherence and increased loss to follow-up. Possible strategies to target these disparities include financial assistance programming, social determinants of health screening, and nurse navigator programs.

It's complicated: The relationship of non-narcotic medications and postoperative opioid use in radical cystectomy patients.

INTRODUCTION: The effect of individual non-narcotic analgesics in cystectomy enhanced recovery after surgery (ERAS) is unknown. Additionally, many non-narcotic medications are associated with side effects pertinent to the cystectomy population. To better understand the actual use and utility of these medications, we sought to characterize the association between non-narcotic medications and milligram morphine equivalent (MME) narcotic score during the postoperative inpatient stay. METHODS: We reviewed 260 consecutive ERAS cystectomy patients. The MME impact of non-narcotic compliance and cumulative dose of medication received was evaluated separately with general linear models. We also assessed relationship of non-narcotic compliance to patient reported pain score, length of stay (LOS), and time to return of bowel function (ROBF) and performed manual review of postoperative documentation to identify reasons for medication noncompliance. RESULTS: Compliance with postoperative acetaminophen, gabapentin, and ketorolac was low. There was an inverse relationship between ketorolac dose and MME on postoperative day 1 (-0.026 MME/mg; P = 0.004) and postoperative day 2 (-0.33 MME/mg; P < 0.001). Compliance with ketorolac was associated with lower MME on postoperative day 1 (26.1 MME v. 33.6 MME; P = 0.023). There were no such associations identified with gabapentin or acetaminophen. Gabapentin compliance was associated with earlier ROBF (3.7 days v. 4.3 days; P = 0.006). Ketorolac compliance was associated with lower pain score on POD1 (3.25 VAS v. 4.07 VAS; P = 0.019) and POD2 (3.05 VAS v. 3.85 VAS; P = 0.040) There was no association between medication compliance and LOS. The most common reasons identified for non-compliance with gabapentin and ketorolac were renal function concerns (38% and 40% respectively), bleeding concerns with ketorolac (20%) and concerns for neurologic adverse effect with gabapentin (16%). CONCLUSION: Compliance with non-narcotic medications in our ERAS cystectomy protocol was poor. There was a modest association with ketorolac and postoperative MME but no association with gabapentin or acetaminophen. Further study will clarify the role of these medications for cystectomy patients. Component specific analysis of protocolized care is valuable and may alter care pathways.

Persistent opioid and benzodiazepine use after radical cystectomy in enhanced recovery after surgery (ERAS) patients.

OBJECTIVES: Opioid use, misuse, and diversion is of paramount concern in the United States. Radical cystectomy is typically managed with some component of opioid pain control. We evaluated persistent opioid and benzodiazepine use after radical cystectomy and assessed the impact of their preoperative use on this outcome. We also explored associations between preoperative use and perioperative outcomes. METHODS AND MATERIALS: We used prospectively maintained data from our enhanced recovery after surgery (ERAS) cystectomy database and the Prescription Reporting with Immediate Medication Utilization Mapping (PRIMUM) database to identify controlled substance prescriptions for radical cystectomy patients. We separated patients by frequency of preoperative opioid and/or benzodiazepine prescriptions (0, 1, 2+) and used these cohorts to explore persistent use (prescription 3-12 months after surgery) alongside perioperative outcomes. RESULTS: Our cohort included 257 patients undergoing cystectomy at a single institution from 2017 to 2021. Preoperative opioid and benzodiazepine prescriptions were documented for 120 (46.7%) and 26 (10.1%) patients, respectively. Persistent opioid use was observed in 20 (14.6%) of opioid-naive patients (no prescriptions in 9 months prior to surgery) while 13 (19.7%) patients with 1 preoperative prescription and 28 (51.9%) patients with 2 or more preoperative prescriptions demonstrated persistent use. New persistent benzodiazepine use occurred in 6 (2.6%) patients. Overall persistent benzodiazepine use was present in 11 (4.3%) patients. In a multivariable model, preoperative opioid and benzodiazepine prescriptions were associated with persistent opioid use (P < 0.001; P = 0.027 respectively). No association was identified between preoperative opioid or benzodiazepine usage and perioperative outcomes including length of stay, return of bowel function, inpatient opioid usage, inpatient or discharge complications, readmissions, or emergency department visits. Inpatient pain scores were noted to be higher in patients with ≥ 2 preoperative opioid prescriptions (P = 0.037). CONCLUSIONS: Persistent opioid use was present in 23.7% of patients, with a new persistent use rate of 14.6%. Benzodiazepine use was less frequent than opioids, with a small number demonstrating new persistent use. Preoperative opioid and benzodiazepine use is associated with persistent opioid use postoperatively. Preoperative opioid and benzodiazepine use did not affect perioperative outcomes in our cohort.

Low co-expression of PD-L1 and oncogenic receptor tyrosine kinases HER2 and cMET in urothelial carcinoma is associated with discordant expression between primary and metastatic sites.

OBJECTIVES: Novel regimens targeting immune checkpoints and the cMET or HER2 pathways are under investigation in metastatic urothelial carcinoma (mUC) though co-expression of these molecular targets has not been defined. We sought to characterize the protein co-expression rates of PD-L1, cMET and HER2 in primary and metastatic mUC lesions and agreement rates in paired biopsies. MATERIALS AND METHODS: We assessed PD-L1, cMET and HER2 protein expression by immunohistochemistry (IHC) in archival mUC samples identified from an institutional database (n = 143). Correlation of expression between primary and metastatic biopsies was performed in patients with available paired biopsies (n = 79). Protein expression levels by predefined thresholds were measured, and Cohen's kappa statistics (κ) were utilized to assess the agreement in expression between paired primary and metastatic samples. RESULTS: In primary tumors (n = 85), high expression of PD-L1, cMET, and HER2 was observed in 14.1%, 34.1%, and 12.9%, respectively. In metastatic samples (n = 143), high expression of PD-L1, cMET and HER2 was detected in 9.8%, 41.3%, and 9.8%, respectively. Expression agreement rates between paired specimens (n = 79) were PD-L1: 79.7% (κ = 0.09), cMET: 69.6% (κ = 0.35), HER2: 84.8% (κ = 0.17). High PD-L1/cMET co-expression was observed in only 5.1% (n = 4) of primary and 4.9% (n = 7) of metastatic specimens. High co-expression of PD-L1/HER2 occurred in 3.8% (n = 3) of primary samples and no metastatic samples. The overall co-expression agreement between paired samples was 55.7% (κ = 0.22) for PD-L1/cMET and 67.1% (κ = 0.06) for PD-L1/HER2, but agreement for high co-expression between paired samples was very low (2.5% for PD-L1/cMET and 0% for PD-L1/HER2). CONCLUSIONS: Tumor co-expression of high cMET or HER2 and PD-L1 is low in this cohort. Agreement of high co-expression between primary and metastatic sites is rare. Biomarker-based strategies used in selection of patients for contemporary trials testing combinations of immune checkpoint inhibitors with either cMET or HER2-targeted agents should account for discordant biomarker expression between primary and metastatic sites.

Prognostic value of galectin-1 and galectin-3 expression in localized urothelial bladder cancer.

Background: Galectin-1 (Gal-1) and Galectin-3 (Gal-3) are carbohydrate binding proteins with a wide range of biological activity, including regulation of cellular adhesion, proliferation, and apoptosis in solid tumors. Prior small studies have reported that Gal-3 expression is associated with progression of disease in urothelial carcinoma (UC), from non-muscle invasive UC progression to muscle invasive UC. We assessed Gal-1 and Gal-3 protein expression H-score utilizing a tissue microarray (TMA) created from 301 cystectomy specimens. Methods: Immunohistochemistry for Gal-1 and Gal-3 was performed on TMA generated from tumor blocks from chemotherapy naïve cystectomy specimens. The variable of interest, H-score, was defined as the product of the percentage of cells staining positive (0-100) and intensity score (0-3) scored by a single pathologist. Survival end points were analyzed using Kaplan-Meier and Cox Proportional Hazards methods. Clinical data including Charlson Comorbidity Index (CCI), pathologic tumor (T) stage, tumor size, node stage, and surgical margins, were included in multivariable analysis. Results: We found that Gal-1 and Gal-3 expression correlated with intratumoral T stage (median Gal-1 H-score was 0 across non-invasive tissue types and 200 in invasive, P<0.01 and median Gal-3 score was 270 across non-invasive tissue types and 70 in invasive, P<0.01). However, the highest intratumoral H-score per cystectomy core did not independently predict for recurrence-free survival (RFS) (Gal-1: HR =1.02, P=0.44, Gal-3: HR =1.01, P=0.65) or OS (Gal-1: HR =1.02, P=0.44, Gal-3: HR =1.01, P=0.72) in this cohort. Significant intratumoral heterogeneity was present for both Gal-1 and Gal-3, with an average difference between the highest and lowest H score was 95 for Gal-1 and 109 for Gal-3 for cystectomy specimens with more than one biopsy. Conclusions: Gal-1 and Gal-3 H-score per bladder did not independently predict for RFS or OS. Intra-tumoral Gal-1/Gal-3 heterogeneity complicates the use of Gal-1 and Gal-3 expression as a prognostic biomarker. Future studies should consider the evaluation of serum and urinary galectins as an approach to mitigate tumor heterogeneity.

Identification of potential biomarkers and novel therapeutic targets through genomic analysis of small cell bladder carcinoma and associated clinical outcomes.

OBJECTIVES: Small cell bladder carcinoma (SCBC) represents a rare histologic variant with a poor prognosis and for which no routine biomarkers exist. Limited reports of genomic sequencing in SCBC have demonstrated a high prevalence of TP53 and RB1 gene mutations, though the prognostic value of these and other gene variants in SCBC remains undefined. In this study, we performed targeted genomic sequencing on a cohort of SCBC patients and correlated genomic findings with clinical outcomes to identify potential novel biomarkers. MATERIALS AND METHODS: Thirty-one patients with SCBC and available treatment-naïve tumor specimens were identified from an institutional database (23 limited stage [LS], 8 extensive stage [ES]). Small cell carcinoma specimens were microdissected and subjected to tumor next-generation whole-exon sequencing with a 592 gene panel. Kaplan-Meier techniques and Cox proportional hazards models were used to evaluate genomic aberration association with relapse-free survival (RFS) and overall survival (OS) in the limited stage cohort. RESULTS: The most common pathogenic gene variants included ARID1A (48%), TP53 (48%) and RB1 (48%). Mutations in genes with potential therapeutic targets not routinely evaluated in SCBC included BRCA1/2 (16%), POLE (13%), JAK2 (13%), PDGFB (13%) and FGFR3 (3%). Multiple novel biomarker candidates showed trends for improvements in OS in the LS subset including ERCC2 (HR 0.322, P = 0.122) and RB1 (HR 0.481, P = 0.182), while LS patients with TP53 mutations (HR 2.730, P = 0.056), and MCL1 gene amplification (HR 4.183, P = 0.018) suggested inferior OS. Additionally, gene or copy number variants with potential prognostic benefit included UBR5 and DAXX (P = 0.02, [hazard ratios nonestimable due to zero events in biomarker positive groups]). CONCLUSIONS: These results support the role for tumor genomic profiling in SCBC and identify multiple potential novel biomarkers and therapeutic targets in this rare disease. Efforts to validate these findings should lead to improved decision-making and treatment outcomes in SCBC.

Impact of dedicated renal enhanced recovery after surgery (RERAS) program on postoperative opioid consumption and evaluation of surgeon-specific compliance to the program.

INTRODUCTION AND OBJECTIVE: Enhanced Recovery After Surgery (ERAS) protocols have been increasingly applied to urologic surgeries such as cystectomy and prostatectomy, though research defining protocols and outcomes for renal ERAS programs (RERAS) for nephrectomy remains limited. We aim to assess perioperative outcomes following implementation of our RERAS protocol modified from ERAS society cystectomy guidelines, as well as describe compliance with protocol guidelines. METHODS: We performed a retrospective cohort analysis of 400 patients who underwent partial or radical nephrectomy between October 2017 and August 2020. RERAS protocol was initiated September 30, 2018, and patients were categorized into pre- and post-RERAS implementation cohorts based on surgery date. Perioperative outcomes including complications, 30-day readmissions, length of stay, and opioid consumption were compared across pre- and post-RERAS cohorts. Protocol compliance was reported based on adherence to program recommendations. RESULTS: Among 400 patients included in analysis, the pre-RERAS cohort included 133 patients and the post-RERAS cohort included 267 patients. There were no differences in overall complications (P = 0.354) and 30-day readmissions (P = 0.078). Length of stay (P < 0.001) and postoperative opioid consumption (P < 0.001) were significantly reduced post-RERAS. We observed an increase in compliance with RERAS recommendations over time (P< 0.001). CONCLUSION: RERAS implementation was associated with decreased length of stay and opioid usage, underscoring the benefits of program adoption in an era of opioid dependence and strained hospital capacity. Successful initiation of a RERAS protocol requires intentional organization and buy in from all providers involved.

Racial and Socioeconomic Disparities in MRI-Fusion Biopsy Utilization to Assess for Prostate Cancer.

OBJECTIVE: To evaluate whether racial disparities in MRI-Bx usage persisted after correction for socioeconomic, demographic, and clinical factors. METHODS: This is a retrospective cohort study of patients who received either MRI-Bx or systematic biopsy (SB) within a single academic medical center between January 2018 - June 2020. For each patient, socioeconomic variables including household income, education, percent below poverty, and unemployment were estimated using 2015 American Community Survey census-tract level data. Chi-square analysis was used to examine differences in clinical and demographic characteristics between the two groups. The Benjamini-Hochberg procedure was used to control false discovery rate (FDR) for multiple testing. RESULTS: Eighteen percent of Black men (53/295) received MRI-Bx while 41% (228/561) of white men received MRI-Bx. Patients coming from highly impoverished areas were less likely to receive MRI-Bx, 25% vs 75%, respectively. In multivariate analysis, race remained significantly different across MRI-Bx and SB groups. Clinical factors including family history, DRE, BMI, and prostate volume were not significantly different between patients receiving MRI-Bx and SB. CONCLUSION: Black men are less likely to receive MRI-Bx than white men, even after adjusting for clinical and socioeconomic characteristics. Further work is necessary to identify and study methods to increase equity in PCa diagnostic testing.

Efficacy of Surgery on the Primary Tumour in Patients with Metastatic Bladder Cancer: A Comprehensive Review.

BACKGROUND: The benefit of surgery of the primary tumor in metastatic bladder cancer is unknown. OBJECTIVE: Perform a comprehensive contemporary literature review on the benefit of surgery of the primary tumor in metastatic bladder cancer. METHODS: Ovid MEDLINE, Ovid EMBASE, and Cochrane Library from January 1, 1990 to April 20, 2020 were queried for relevant articles published in English. Each article was evaluated by at least two content experts prior to inclusion which were blinded to the other's evaluation. A third content expert was used when there was not a unanimous decision. Additional articles were added at the discretion of the authors. RESULTS: Long-term survival is possible in patients with initially unresectable and/or limited metastatic disease. Multi-modal therapy with chemotherapy and surgery have the most favorable outcomes when compared to single treatment modalities in selected populations. Patients who demonstrate a robust response to pre-surgical therapy are likely to benefit the most from consolidative surgery. Patients with distant metastatic disease may benefit from consolidative surgery; however, this benefit may only be seen in those with metastatic disease limited to one site. CONCLUSIONS: Surgery of the primary tumor in metastatic bladder cancer either in the setting of surgery alone, consolidative therapy or coupled with adjuvant therapy may be beneficial in well selected patients and should generally be limited to those who have a response to primary chemotherapy. Randomized clinical control trials are needed to further our understanding of the role of surgery in metastatic bladder cancer.

Reduced Dose Intravesical Bacillus Calmette-Guérin: Why It Might Not Matter.

When it comes to the treatment of patients with non-muscle-invasive bladder cancer (NMIBC) with intravesical bacillus Calmette-Guérin (BCG), two questions must be considered: 1) what dose to give, and 2) for how long? The issue of optimal dose and duration has been the subject of several randomized trials and is especially pertinent in the context of a global BCG shortage. Despite this, there appears to be uncertainty as to whether BCG dose or duration may be compromised in the event of shortage. As such, we wish to summarize the available evidence as an aid to the practicing urologist.

Genomic analysis of response to bacillus Calmette-Guérin (BCG) treatment in high-grade stage 1 bladder cancer patients.

BACKGROUND: Intravesical bacillus Calmette-Guérin (BCG) therapy is standard treatment for high-risk non-muscle invasive bladder cancer (NMIBC) but overall efficacy is low, and no reliable predictive biomarkers currently exist to refine patient selection. We performed genomic analysis on high-grade (HG) T1 NMIBCs to determine if response to therapy is predicted by certain mutational and/or expressional changes. METHODS: Patients with HG T1 NMIBC treated with induction BCG were stratified by response into durable and non-durable responders. Baseline tumor samples were subjected to targeted DNA sequencing and whole-exome RNAseq. Genomic variants differing significantly between response groups were analyzed using Ingenuity Pathway Analysis (IPA) software. Variant selection was refined to target potential biomarker candidates for responsiveness to BCG. RESULTS: Among 42 patients, the median follow-up was 51.7 months and 40.5% (n=17) were durable BCG responders. Deleterious mutations in the RNA sequence of JCHAIN, S100A7, CLEC2B, and ANXA10 were more common in non-durable responders. Mutations in MCL1 and MSH6 detected on targeted sequencing were more commonly found in durable responders. Of all deleterious DNA and RNA mutations identified, only MCL1 was significantly associated with longer recurrence free survival (RFS) (P=0.031). CONCLUSIONS: Differences in the genomic profiles of HG T1 NMIBC tumors exist between those who show durable response to BCG and those who do not. Using pathway analysis, those differences imply upregulation of several interconnected inflammatory pathways among responders. Specific variants identified here, namely MCL1, are candidates for further study and, if clinically validated, may serve as useful biomarkers in the future.

Contemporary Outcomes of Patients with Nonmuscle-Invasive Bladder Cancer Treated with bacillus Calmette-Guérin: Implications for Clinical Trial Design.

PURPOSE: Recurrent disease after bacillus Calmette-Guérin treatment presents a therapeutic challenge. To aid trial development, the U.S. Food and Drug Administration defined "adequate bacillus Calmette-Guérin" therapy and adopted the "bacillus Calmette-Guérin unresponsive" disease state. Available data for efficacy benchmark comparison are outdated, leading to concerns about appropriate control arms and sample size calculations. We describe a contemporary cohort of patients with nonmuscle-invasive bladder cancer treated with intravesical bacillus Calmette-Guérin, and provide benchmark outcomes data. MATERIALS AND METHODS: We retrospectively reviewed patients receiving adequate bacillus Calmette-Guérin therapy at a tertiary cancer center between January 2004 and August 2018. Unadjusted univariable analysis was conducted using the Pearson chi-square test. Kaplan-Meier estimates for recurrence-free survival-high grade, progression-free survival-muscle-invasive bladder cancer and overall survival were used to create survival curves and compared using the log-rank test. RESULTS: Of the 542 patients who received adequate bacillus Calmette-Guérin, 518 (90%) had European Association Urology high risk disease, with carcinoma in situ present in 175 (32%). With a median followup of 47.8 months, freedom from high grade recurrence at 1, 3 and 5 years was 81%, 76% and 74%, respectively, and progression-free survival was 97%, 93% and 92%. Progression to muscle invasion at 5 years was exclusively seen in patients with high risk disease (progression-free survival 91%; log-rank test, p=0.024). CONCLUSIONS: A contemporary cohort of patients with nonmuscle-invasive bladder cancer treated with adequate bacillus Calmette-Guérin demonstrated markedly better outcomes than seen in prior studies. These data could be used in the design of clinical trials, to guide power calculations, as well as serve as benchmarks for comparison to evaluate nonrandomized studies.

Association of 5-Alpha Reductase Inhibitor Use with Prostate Specific Antigen Level at the Time of Urology Referral in a Retrospective Cohort at a Large, Integrated Health Care System.

INTRODUCTION: 5-Alpha reductase inhibitor (5-ARI) use leads to a 50% decline in serum prostate specific antigen (PSA) without a concomitant decrease in prostate cancer (PCa) risk. We hypothesize that failure to account for the effect of 5-ARI use on serum PSA leads to increased PCa risk at urology referral among 5-ARI users. METHODS: This is a retrospective cohort study for the years 2018-2019. Atrium Health is a large, vertically integrated health system with over 900 care locations in North Carolina and South Carolina. Men ≥40 years old during 2018-2019 who had a PSA test performed were included. We determined differences in corrected serum PSA level at the time of referral to urology. 5-ARI users and nonusers were compared using the chi-square test, Student's t-test and gamma regression. RESULTS: From 2018-2019, there were 91,368 men who underwent PSA testing, including 2,939 5-ARI users. At referral, 5-ARI users had similar uncorrected median PSA (5.8 vs 5.6 ng/ml, p=0.05). After correcting for the effect of 5-ARIs on PSA, 5-ARI users had a median PSA of 11.6 ng/ml at urology referral, compared to 5.6 ng/ml in nonusers. CONCLUSIONS: Men taking 5-ARIs have higher corrected serum PSA at time of referral to urology. As the unadjusted PSA at referral to urology for PCa risk was similar between 5-ARI users and nonusers, this indicates that the effect of 5-ARI use on serum PSA levels is not routinely accounted for when assessing PCa risk.

The obesity paradox: defining the impact of body mass index and diabetes mellitus for patients with non-muscle-invasive bladder cancer treated with bacillus Calmette-Guérin.

OBJECTIVES: To evaluate if the obesity paradox, wherein obesity portends worse overall prognosis for a disease but improved outcomes for patients receiving immunotherapy, exists for patients receiving bacillus Calmette-Guérin (BCG) in a contemporary cohort. PATIENTS AND METHODS: We performed an Institutional Review Board-approved database review to identify patients with non-muscle-invasive bladder cancer (NMIBC) completing at least an induction course of BCG. Clinicopathological variables collected included: body mass index (BMI), medications, and diabetes mellitus (DM). Outcomes of interest included: recurrence-free (RFS), progression-free (PFS), cancer-specific (CSS), and overall survival (OS). Univariate and multivariate modelling were used to evaluate the association between outcomes and clinical factors. RESULTS: A total of 579 patients (median follow-up 4.6 years) received BCG induction for NMIBC; 90% had high-grade disease (47.2% clinical stage T1). In all, 75.7% of patients were overweight or obese and 18% had DM. Aspirin, statins, metformin and ß-blockers were used in 34%, 42%, 11%, and 29% of patients, respectively. Overweight and obese patients had improved PFS, CSS and OS. DM was associated with worse RFS. Medications of interest had no association with outcomes. CONCLUSION: Elevated BMI is associated with improved outcomes in patients with NMIBC treated with BCG immunotherapy. Patients with DM are at increased risk of recurrence. These findings support a potential obesity paradox in bladder cancer. Evaluation of the underlying mechanism and the role of global patient assessment, counselling, and risk factor modification are warranted.

Variability in adherence to guidelines based management of nonmuscle invasive bladder cancer among Society of Urologic Oncology (SUO) members.

PURPOSE: The American Urological Association (AUA) introduced evidence-based guidelines for the management of nonmuscle invasive bladder cancer (NMIBC) in 2016. We sought to assess the implementation of these guidelines among members of the Society of Urologic Oncology (SUO) with an aim to identifying addressable gaps. METHODS AND MATERIALS: An SUO approved survey was distributed to 747 members from December 28, 2018 to February 2, 2019. This 14-question online survey (Qualtrics, SAP SE, Germany) consisted of 38 individual items addressing specific statements from the AUA NMIBC guidelines within 3 broad categories - initial diagnosis, surveillance, and imaging/biomarkers. Adherence to guidelines was assessed by dichotomizing responses to each item that was related to recommended action statement within the guidelines. Statistical analysis was applied using Pearson's chi-squared test, where a P-value of <0.05 was considered statistically significant. RESULTS: A total of 121 (16.2%) members completed the survey. Members reported a mean of 71% guidelines adherence; adherence was higher for the intermediate- and high-risk subgroups (82% and 76%, respectively) compared to low-risk (58%). Specifically, adherence to guideline recommended cystoscopic surveillance intervals for low-risk disease differed based on clinical experience (60.9% [<10 years] vs. 36.8% [≥10 years], P = 0.01) and type of fellowship training (55.2% [urologic oncology] vs. 28.0% [none/other], P = 0.02). CONCLUSION: Adherence to guidelines across risk-categories was higher for intermediate- and high-risk patients. Decreased adherence observed for low-risk patients resulted in higher than recommended use of cytology, imaging, and surveillance cystoscopy. These results identify addressable gaps and provide impetus for targeted interventions to support high-value care, especially for low-risk patients.

Risk-adapted management of low-grade bladder tumours: recommendations from the International Bladder Cancer Group (IBCG).

OBJECTIVE: To provide a contemporary update and recommendations for the diagnosis and management of low-grade non-muscle-invasive bladder cancer (BCa) based on current literature and expert consensus of the International Bladder Cancer Group. METHODS: We reviewed published trials, guidelines, meta-analyses and reviews (up to March 2019) and provide recommendations on baseline evaluations, treatment, endpoints, study design and surveillance protocols. RESULTS: Low-grade Ta BCa poses minimal risk to patients in terms of progression and disease-specific survival. Thus, to minimize patient morbidity, this entity should be managed appropriately. After initial diagnosis of low-grade Ta tumour, subsequent stable, low-grade-appearing recurrences can be managed conservatively with office cystoscopy and fulguration or even followed using an active surveillance protocol. Intravesical therapy other than single-dose peri-operative chemotherapy instillation should be used judiciously, and only after assigning appropriate risk points. Routine use of urinary cytology - other than at initial risk stratification, or for patients on active surveillance without therapy - is not recommended; and surveillance cystoscopy may be discontinued after 5 years. Clinical studies in this group of patients should focus on recurrence rates, and time to recurrence, rather than progression events. CONCLUSIONS: The International Bladder Cancer Group has developed formal recommendations regarding the diagnosis, treatment and surveillance of low-grade non-muscle-invasive BCa to minimize morbidity and encourage uniformity among studies in this disease.

Radical cystectomy in women: Impact of the robot-assisted versus open approach on surgical outcomes.

OBJECTIVES: To perform a comparison of complications following open versus robot-assisted radical cystectomy (RC) among women who undergo the procedure. Studies comparing robotic to open RC have been mixed without a clear delineation of which patients benefit the most from one modality vs. the other, leading to continued debate. PATIENTS AND METHODS: This was a retrospective study of women who underwent either open or robotic RC at the MD Anderson Cancer Center from 1/2014 to 6/2018. Co-morbidities, pathologic data, and complications were assessed with descriptive statistics, along with uni- and multivariable logistic regression. RESULTS: 122 women underwent either open (n = 76) or robotic (n = 46) RC. Open RC was associated with greater intraoperative blood loss (median EBL 775 ml vs. 300 ml, P < 0.001). In both uni- and multivariable analyses, open RC was associated with a greater odds of intraoperative transfusion compared to robotic RC (odds ratio 6.49, 95% CI 2.85-14.78, P < 0.001). Women undergoing open RC were also at greater odds of receiving 4 or more units of packed red blood cells (odds ratio 5.46 (1.75-17.02), P = 0.003). Robotic RC conferred a higher median lymph node yield (27 vs. 20 nodes, P, <0.001) and operative times (median 513 min vs. 391.5 min, P < 0.001). There were no differences in margin positivity, length of stay, or readmission rates at 30 and 90 days. CONCLUSIONS: Robotic RC was associated with a significantly lower risk of transfusion and EBL, and a higher median lymph node yield and operative time. Unique anatomic considerations may in part be responsible for these findings.

A Case for Risk-adapted Management of Low-grade Bladder Tumors.

Management of low-grade bladder cancer should focus on minimizing morbidity and costs given the excellent oncologic outcomes.
