NCCN Guidelines® Insights: Bladder Cancer, Version 3.2024.

Bladder cancer, the sixth most common cancer in the United States, is most commonly of the urothelial carcinoma histologic subtype. The clinical spectrum of bladder cancer is divided into 3 categories that differ in prognosis, management, and therapeutic aims: (1) non-muscle-invasive bladder cancer (NMIBC); (2) muscle invasive, nonmetastatic disease; and (3) metastatic bladder cancer. These NCCN Guidelines Insights detail recent updates to the NCCN Guidelines for Bladder Cancer, including changes in the fifth edition of the WHO Classification of Tumours: Urinary and Male Genital Tumours and how the NCCN Guidelines aligned with these updates; new and emerging treatment options for bacillus Calmette-Guérin (BCG)-unresponsive NMIBC; and updates to systemic therapy recommendations for advanced or metastatic disease.

Symptomatic and functional recovery after transurethral resection of bladder tumor: Data from ecological momentary symptom assessment.

OBJECTIVES: To quantitatively describe the nature, severity, and duration of symptoms and functional impairment during recovery from transurethral resection of bladder tumors. MATERIALS AND METHODS: All patients scheduled for transurethral resection were approached for enrollment in a text-message based ecological momentary symptom assessment platform. Nine patients reported outcomes were measured 7 days before surgery and on postoperative days 1, 2, 3, 5, 7, 10, and 14 using a 5-point Likert scale. Self-reported degree of hematuria was collected using a visual scale. Clinical data was collected via retrospective chart review. RESULTS: A total of 159 patients were analyzed. Postoperative symptoms were overall mild, with the largest differences from baseline to postoperative day 1 seen in dysuria (median 0/5 vs. 3/5) and ability to work (median 5/5 vs. 4/5). Recovery was generally rapid, with 76% of patients reporting ≥4/5 agreement with the statement "I feel recovered from surgery" by postoperative day 2, although 15% of patients reported persistently lower levels of agreement on postoperative day 10 or 14. Patients undergoing larger resections (≥2cm) did take longer to return to baseline in multiple symptom domains, but the difference of medians vs. those undergoing smaller resections was less than 1 day across all domains. Multivariable analysis suggested that receiving perioperative intravesical chemotherapy was associated with longer time to recovery. 84% of patients reported clear yellow urine by postoperative day 3. CONCLUSION: In this population, hematuria and negative effects on quality of life resulting from transurethral resection of bladder tumors were generally mild and short-lived, although a small number of patients experienced longer recoveries.

Real-time estimation of nephron activity with a linear measurement system (RENAL-MS) predicts postoperative estimated glomerular filtration rate.

OBJECTIVE: To determine whether a simple point-of-care measurement system estimating renal parenchymal volume using tools ubiquitously available could be used to replace nuclear medicine renal scintigraphy (NMRS) in current clinical practice to predict estimated glomerular filtration rate (eGFR) after nephrectomy by estimating preoperative split renal function. PATIENTS AND METHODS: We performed a retrospective review of patients who underwent abdominal cross-sectional imaging (computed tomography/magnetic resonance imaging) and mercaptoacetyltriglycine (MAG3) NMRS prior to total nephrectomy at a single institution. We developed the real-time estimation of nephron activity with a linear measurement system (RENAL-MS) method of estimating postoperative renal function via the following technique: renal parenchymal volume of the removed kidney relative to the remaining kidney was estimated as the product of renal length and the average of six renal parenchymal thickness measurements. The utility of this value was compared to the utility of the split renal function measured by MAG3 for prediction of eGFR and new onset Stage 3 chronic kidney disease (CKD) at ≥90 days after nephrectomy using uni- and multivariate linear and logistic regression. RESULTS: A total of 57 patients met the study criteria. The median (interquartile range [IQR]) age was 69 (61-80) years. The median (IQR) pre- and postoperative eGFR was 74 (IQR 58-90) and 46 (35-62) mL/min/1.73 m2 , respectively. [Correction added on 29 December 2023, after first online publication: The data numbers in the preceding sentence have been corrected.] Correlations between actual and predicted postoperative eGFR were similar whether the RENAL-MS or NMRS methods were used, with correlation using RENAL-MS being slightly numerically but not statistically superior (R = 0.82 and 0.76; P = 0.138). Receiver operating characteristic curve analysis using logistic regression estimates incorporating age, sex, and preoperative creatinine to predict postoperative Stage 3 CKD were similar between RENAL-MS and NMRS (area under the curve 0.93 vs. 0.97). [Correction added on 29 December 2023, after first online publication: The data numbers in the preceding sentence have been corrected.] CONCLUSION: A point-of-care tool to estimate renal parenchymal volume (RENAL-MS) performed equally as well as NMRS to predict postoperative eGFR and de novo Stage 3 CKD after nephrectomy in our population, suggesting NMRS may not be necessary in this setting.

Efficacy of Messenger RNA-1273 Against Severe Acute Respiratory Syndrome Coronavirus 2 Acquisition in Young Adults From March to December 2021.

Background: The efficacy of messenger RNA (mRNA)-1273 against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is not well defined, particularly among young adults. Methods: Adults aged 18-29 years with no known history of SARS-CoV-2 infection or prior vaccination for coronavirus disease 2019 (COVID-19) were recruited from 44 US sites from 24 March to 13 September 2021 and randomized 1:1 to immediate vaccination (receipt of 2 doses of mRNA-1273 vaccine at months 0 and 1) or the standard of care (receipt of COVID-19 vaccine). Randomized participants were followed up for SARS-CoV-2 infection measured by nasal swab testing and symptomatic COVID-19 measured by nasal swab testing plus symptom assessment and assessed for the primary efficacy outcome. A vaccine-declined observational group was also recruited from 16 June to 8 November 2021 and followed up for SARS-CoV-2 infection as specified for the randomized participants. Results: The study enrolled 1149 in the randomized arms and 311 in the vaccine-declined group and collected >122 000 nasal swab samples. Based on randomized participants, the efficacy of 2 doses of mRNA-1273 vaccine against SARS-CoV-2 infection was 52.6% (95% confidence interval, -14.1% to 80.3%), with the majority of infections due to the Delta variant. Vaccine efficacy against symptomatic COVID-19 was 71.0% (95% confidence interval, -9.5% to 92.3%). Precision was limited owing to curtailed study enrollment and off-study vaccination censoring. The incidence of SARS-CoV-2 infection in the vaccine-declined group was 1.8 times higher than in the standard-of-care group. Conclusions: mRNA-1273 vaccination reduced the incidence of SARS-CoV-2 infection from March to September 2021, but vaccination was only one factor influencing risk. Clinical Trials Registration: NCT04811664.

Clinical Performance of Technetium-99m-Sestamibi SPECT/CT Imaging in Differentiating Oncocytic Tumors From Renal Cell Carcinoma in Routine Clinical Practice.

PURPOSE: Technetium-99m-sestamibi single-photon emission CT/x-ray CT is an emerging clinical tool to differentiate oncocytic tumors from renal cell carcinomas. We report data from a large institutional cohort of patients who underwent technetium-99m-sestamibi scans during evaluation of renal masses. MATERIALS AND METHODS: Patients who underwent technetium-99m-sestamibi single-photon emission CT/x-ray CT between February 2020 and December 2021 were included in the analysis. Scans were defined as "hot" for oncocytic tumor when technetium-99m-sestamibi uptake was qualitatively equivalent or higher between the mass of interest and normal renal parenchyma, suggesting oncocytoma, hybrid oncocytic/chromophobe tumor, or chromophobe renal cell carcinoma. Demographic, pathological, and management strategy data were compared between "hot" and "cold" scans. For individuals who underwent diagnostic biopsy or extirpative procedures, the concordance between radiological findings and pathology was indexed. RESULTS: A total of 71 patients (with 88 masses) underwent technetium-99m-sestamibi imaging with 60 (84.5%) patients having at least 1 "cold" mass on imaging and 11 (15.5%) patients exhibiting only "hot" masses. Pathology was available for 7 "hot" masses, with 1 biopsy specimen (14.3%) being discordant (clear cell renal cell carcinoma). Five patients with "cold" masses underwent biopsy. Out of 5 biopsied masses, 4 (80%) were discordant oncocytomas. Of the extirpated specimens, 35/40 (87.5%) harbored renal cell carcinoma and 5/40 (12.5%) yielded discordant oncocytomas. In sum, 20% of pathologically sampled masses that were "cold" on technetium-99m-sestamibi imaging still harbored oncocytoma/hybrid oncocytic/chromophobe tumor/chromophobe renal cell carcinoma. CONCLUSIONS: Further work is needed to define utility of technetium-99m-sestamibi in real-world clinical practice. Our data suggest this imaging strategy is not yet ready to replace biopsy.

Pathological and Clinical Outcomes in a Large Surveillance and Intervention Cohort of Radiographically Cystic Renal Masses.

PURPOSE: We evaluated oncologic risks in a large cohort of patients with radiographic cystic renal masses who underwent active surveillance or intervention. MATERIALS AND METHODS: A single-institutional database of 4,340 kidney lesions managed with either active surveillance or intervention between 2000-2020 was queried for radiographically cystic renal masses. Association of radiographic tumor characteristics and high-grade pathology was evaluated. RESULTS: We identified 387 radiographically confirmed cystic lesions in 367 patients. Of these, 247 were resected (n=240) or ablated (n=7; n=247, 203 immediate vs 44 delayed intervention). Pathologically, 23% (n=56) demonstrated high-grade pathology. Cystic features were explicitly described by pathology in only 18% (n=33) of all lesions and in 7% (n=4) of high-grade lesions. Of the intervention cohort, African American race, male gender, and Bosniak score were associated with high-grade pathology (P < .05). On active surveillance (n=184), Bosniak IV lesions demonstrated faster growth rates than IIF and III lesions (2.7 vs 0.6 and 0.5 mm/y, P ≤ .001); however, growth rates were not associated with high-grade pathology (P = .5). No difference in cancer-specific survival was identified when comparing intervention vs active surveillance at 5 years (99% vs 100%, P = .2). No difference in recurrence was observed between immediate intervention vs delayed intervention (P > .9). CONCLUSIONS: A disconnect between "cystic" designation on imaging and pathology exists for renal lesions. Over 80% of radiographic Bosniak cystic lesions are not described as "cystic" on pathology reports. More than 1 in 5 resected cystic renal lesions demonstrated high-grade disease. Despite this finding, judiciously managed active surveillance ± delayed intervention is a safe and effective management option for most radiographic cystic renal masses.

A Phase 1 Trial of Durvalumab in Combination with Bacillus Calmette-Guerin (BCG) or External Beam Radiation Therapy in Patients with BCG-unresponsive Non-muscle-Invasive Bladder Cancer: The Hoosier Cancer Research Network GU16-243 ADAPT-BLADDER Study.

BACKGROUND: Novel treatments and trial designs remain a high priority for bacillus Calmette-Guerin (BCG)-unresponsive non-muscle-invasive bladder cancer (NMIBC) patients. OBJECTIVE: To evaluate the safety and preliminary efficacy of anti-PD-L1 directed therapy with durvalumab (D), durvalumab plus BCG (D + BCG), and durvalumab plus external beam radiation therapy (D + EBRT). DESIGN, SETTING, AND PARTICIPANTS: A multicenter phase 1 trial was conducted at community and academic sites. INTERVENTION: Patients received 1120 mg of D intravenously every 3 wk for eight cycles. D + BCG patients also received full-dose intravesical BCG weekly for 6 wk with BCG maintenance recommended. D + EBRT patients received concurrent EBRT (6 Gy × 3 in cycle 1 only). OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Post-treatment cystoscopy and urine cytology were performed at 3 and 6 -mo, with bladder biopsies required at the 6-mo evaluation. The recommended phase 2 dose (RP2D) for each regimen was the primary endpoint. Secondary endpoints included toxicity profiles and complete response (CR) rates. RESULTS AND LIMITATIONS: Twenty-eight patients were treated in the D (n = 3), D + BCG (n = 13), and D + EBRT (n = 12) cohorts. Full-dose D, full-dose BCG, and 6 Gy fractions × 3 were determined as the RP2Ds. One patient (4%) experienced a grade 3 dose limiting toxicity event of autoimmune hepatitis. The 3-mo CR occurred in 64% of all patients and in 33%, 85%, and 50% within the D, D + BCG, and D + EBRT cohorts, respectively. Twelve-month CRs were achieved in 46% of all patients and in 73% of D + BCG and 33% of D + EBRT patients. CONCLUSIONS: D combined with intravesical BCG or EBRT proved feasible and safe in BCG-unresponsive NMIBC patients. Encouraging preliminary efficacy justifies further study of combination therapy approaches. PATIENT SUMMARY: Durvalumab combination therapy can be safely administered to non-muscle-invasive bladder cancer patients with the goal of increasing durable response rates.

Long-Term Results of a Phase 3 Randomized Prospective Trial of Erectile Tissue-Sparing Intensity-Modulated Radiation Therapy for Men With Clinically Localized Prostate Cancer.

PURPOSE: The objective of this study was to determine whether limiting the doses delivered to the penile bulb (PB) and corporal bodies with intensity modulated radiation therapy (IMRT) preserves erectile function compared with standard IMRT in men with prostate cancer. METHODS AND MATERIALS: A total of 117 patients with low- to intermediate-risk, clinical T1a-T2c prostate adenocarcinoma were enrolled in a single-institution, prospective, single-blind, phase 3 randomized trial. All received definitive IMRT to 74 to 80 Gy in 37 to 40 fractions and standard IMRT (s-IMRT) or erectile tissue-sparing IMRT (ETS-IMRT), which placed additional planning constraints that limited the D90 to the penile bulb and corporal bodies to ≤15 Gy and ≤7 Gy, respectively. Erectile potency was assessed with components of the International Index of Erectile Function and phosphodiesterase type 5 inhibitor (PDE5) medication records. RESULTS: Sixty-two patients received ETS-IMRT, and 54 received s-IMRT; 1 patient did not receive radiation therapy. Before treatment, all patients reported erectile potency. No patients received androgen deprivation therapy. In the intention-to-treat analysis, treatment arms did not differ in potency preservation at 24 months (37.1% ETS-IMRT vs 31.5% s-IMRT, P = .53). Of 85 evaluable patients with International Index of Erectile Function and PDE5 medication follow-up, erectile potency was seen in 47.9% of patients in the ETS-IMRT arm and 46.0% of patients in the s-IMRT arm (P = .86). PDE5 inhibitors were initiated in 41.7% of ETS-IMRT patients and 35.1% of s-IMRT patients (P = .54). Among all patients enrolled, there was no difference in freedom from biochemical failure between those treated with ETS-IMRT and s-IMRT (5-year 91.8% vs 90.7%, respectively, P = .77), with a median follow-up of 7.4 years. There were no differences in acute or late gastrointestinal or genitourinary toxicity. An unplanned per-protocol analysis demonstrated no differences in potency preservation or secondary endpoints between patients who exceeded erectile tissue-sparing constraints and those who met constraints, although power was limited by attrition and unplanned dosimetric crossover. CONCLUSIONS: ETS-IMRT that strictly limits dose to the penile bulb and corporal bodies is safe and feasible. Use of this planning technique did not show an effect on potency preservation outcomes at 2 years, though power to detect a difference was limited.

No difference in renal function outcomes for patients with oncocytoma managed with active surveillance vs. partial nephrectomy.

OBJECTIVES: To investigate the difference in renal function outcomes for patients with oncocytomas undergoing active surveillance (AS) vs. partial nephrectomy (PN). METHODS: We reviewed our institutional database for patients with biopsy/surgically confirmed oncocytoma from 2000-2020. The primary outcome was to assess for differences in renal function outcomes in patients undergoing AS vs. PN. We fit two generalized estimating equation (GEE) with an interaction term between follow up time and management strategy to predict 1) mean eGFR for patients managed with AS and PN and 2) the probability of progression to CKD stage III or greater. RESULTS: We identified 114 eligible patients, of which 32 were managed with AS. Median follow-up was 21 months vs. 44 months for PN vs. AS patients. AS patients tended to be older (median: 72 years vs. 65 years, P<0.001) and have lower baseline renal function (median: eGFR: 71 mL/min/1.73m2 vs. 82 mL/min/1.73m2, P<0.001) compared with PN patients. Renal mass size from baseline imaging was similar between patients undergoing PN vs. AS (2.8 cm vs. 2.9 cm, P=0.634). For patients undergoing PN vs. AS, there was not a significant difference in predicted longitudinal eGFR (-0.079, 95% CI -0.18-0.023, P=0.129) or predicted probability of progression to CKD stage III or greater (OR: 0.61, 95% CI: 0.16-2.33, P=0.47). CONCLUSIONS: In our institutional dataset, patients undergoing AS or PN with an oncocytoma had similar long-term renal function outcomes. Given similar renal function outcomes in patients undergoing AS and PN, surgery should remain reserved for select patients with oncocytomas.

Analysis of MRE11 and Mortality Among Adults With Muscle-Invasive Bladder Cancer Managed With Trimodality Therapy.

Importance: Bladder-preserving trimodality therapy can be an effective alternative to radical cystectomy for treatment of muscle-invasive bladder cancer (MIBC), but biomarkers are needed to guide optimal patient selection. The DNA repair protein MRE11 is a candidate response biomarker that has not been validated in prospective cohorts using standardized measurement approaches. Objective: To evaluate MRE11 expression as a prognostic biomarker in MIBC patients receiving trimodality therapy using automated quantitative image analysis. Design, Setting, and Participants: This prognostic study analyzed patients with MIBC pooled from 6 prospective phase I/II, II, or III trials of trimodality therapy (Radiation Therapy Oncology Group [RTOG] 8802, 8903, 9506, 9706, 9906, and 0233) across 37 participating institutions in North America from 1988 to 2007. Eligible patients had nonmetastatic MIBC and were enrolled in 1 of the 6 trimodality therapy clinical trials. Analyses were completed August 2020. Exposures: Trimodality therapy with transurethral bladder tumor resection and cisplatin-based chemoradiation therapy. Main Outcomes and Measures: MRE11 expression and association with disease-specific (bladder cancer) mortality (DSM), defined as death from bladder cancer. Pretreatment tumor tissues were processed for immunofluorescence with anti-MRE11 antibody and analyzed using automated quantitative image analysis to calculate a normalized score for MRE11 based on nuclear-to-cytoplasmic (NC) signal ratio. Results: Of 465 patients from 6 trials, 168 patients had available tissue, of which 135 were analyzable for MRE11 expression (median age of 65 years [minimum-maximum, 34-90 years]; 111 [82.2%] men). Median (minimum-maximum) follow-up for alive patients was 5.0 (0.6-11.7) years. Median (Q1-Q3) MRE11 NC signal ratio was 2.41 (1.49-3.34). Patients with an MRE11 NC ratio above 1.49 (ie, above first quartile) had a significantly lower DSM (HR, 0.50; 95% CI, 0.26-0.93; P = .03). The 4-year DSM was 41.0% (95% CI, 23.2%-58.0%) for patients with an MRE11 NC signal ratio of 1.49 or lower vs 21.0% (95% CI, 13.4%-29.8%) for a ratio above 1.49. MRE11 NC signal ratio was not significantly associated with overall survival (HR, 0.84; 95% CI, 0.49-1.44). Conclusions and Relevance: Higher MRE11 NC signal ratios were associated with better DSM after trimodality therapy. Lower MRE11 NC signal ratios identified a poor prognosis subgroup that may benefit from intensification of therapy.

Serious Bacterial Infections in Young Febrile Infants With Positive Urinalysis Results.

It is unknown whether febrile infants 29 to 60 days old with positive urinalysis results require routine lumbar punctures for evaluation of bacterial meningitis. OBJECTIVE: To determine the prevalence of bacteremia and/or bacterial meningitis in febrile infants ≤60 days of age with positive urinalysis (UA) results. METHODS: Secondary analysis of a prospective observational study of noncritical febrile infants ≤60 days between 2011 and 2019 conducted in the Pediatric Emergency Care Applied Research Network emergency departments. Participants had temperatures ≥38°C and were evaluated with blood cultures and had UAs available for analysis. We report the prevalence of bacteremia and bacterial meningitis in those with and without positive UA results. RESULTS: Among 7180 infants, 1090 (15.2%) had positive UA results. The risk of bacteremia was higher in those with positive versus negative UA results (63/1090 [5.8%] vs 69/6090 [1.1%], difference 4.7% [3.3% to 6.1%]). There was no difference in the prevalence of bacterial meningitis in infants ≤28 days of age with positive versus negative UA results (∼1% in both groups). However, among 697 infants aged 29 to 60 days with positive UA results, there were no cases of bacterial meningitis in comparison to 9 of 4153 with negative UA results (0.2%, difference -0.2% [-0.4% to -0.1%]). In addition, there were no cases of bacteremia and/or bacterial meningitis in the 148 infants ≤60 days of age with positive UA results who had the Pediatric Emergency Care Applied Research Network low-risk blood thresholds of absolute neutrophil count <4 × 103 cells/mm3 and procalcitonin <0.5 ng/mL. CONCLUSIONS: Among noncritical febrile infants ≤60 days of age with positive UA results, there were no cases of bacterial meningitis in those aged 29 to 60 days and no cases of bacteremia and/or bacterial meningitis in any low-risk infants based on low-risk blood thresholds in both months of life. These findings can guide lumbar puncture use and other clinical decision making.

NCCN Guidelines® Insights: Bladder Cancer, Version 2.2022.

The NCCN Guidelines for Bladder Cancer provide recommendations for the diagnosis, evaluation, treatment, and follow-up of patients with bladder cancer and other urinary tract cancers (upper tract tumors, urothelial carcinoma of the prostate, primary carcinoma of the urethra). These NCCN Guidelines Insights summarize the panel discussion behind recent important updates to the guidelines regarding the treatment of non-muscle-invasive bladder cancer, including how to treat in the event of a bacillus Calmette-Guérin (BCG) shortage; new roles for immune checkpoint inhibitors in non-muscle invasive, muscle-invasive, and metastatic bladder cancer; and the addition of antibody-drug conjugates for metastatic bladder cancer.

Association of tumor size and surgical approach with oncological outcomes and overall survival in patients with adrenocortical carcinoma.

OBJECTIVES: To investigate the association of surgical approach with outcomes in patients with adrenocortical carcinomas smaller and larger than 6 cm in size. METHODS: We reviewed the national cancer database for patients undergoing minimally invasive adrenalectomy (MIA) and open adrenalectomy (OA) from 2010 to 2017. To adjust for differences between patients undergoing MIA and OA, we performed propensity score matching within each size strata of ≤6 cm, 6.1 to 10 cm, and 10.1 to 20 cm. We fit generalized estmiating equations with a logit link function to assess for the association of surgical approach with positive surgical margins and a Cox proportional hazards model to assess for the association of surgical approach with overall survival. RESULTS: We identified 364 patients that underwent MIA (182) and OA (182) in the matched cohort.  We noted 21% and 18% of patients undergoing MIA and OA had a positive surgical margin, respectively. We did not identify a significant association between surgical approach and positive surgical margins in the cohort as a whole or within each of strata. Furthermore, we did not appreciate a significant association between surgical approach and overall survival in the cohort as a whole or within each size strata. CONCLUSION: In the National Cancer Database, patients undergoing MIA had similar positive surgical margins and overall survival compared with OA for masses ≤6 cm, 6.1 to 10cm, and >10 cm in size. Patients undergoing MIA should be carefully selected with surgical oncologic integrity being the primary determinants of surgical approach.

Association of Surgical Approach With Treatment Burden, Oncological Effectiveness, and Perioperative Morbidity in Adrenocortical Carcinoma.

MICROABSTRACT: In the National Cancer Database (NCDB), patients treated with minimally invasive adrenalectomy (MIA) for adrenocortical carcinoma (ACC) had similar oncological outcomes and cumulative treatment burden with less morbidity compared with open adrenalectomy (OA). Although OA remains the standard of care for adrenal lesions concerninge for malignancy, MIA in appropriately selected patients may offer equivalent oncological outcomes. INTRODUCTION/BACKGROUND: We investigated the cumulative treatment burden, oncological effectiveness, and perioperative morbidity in patients undergoing MIA compared with (OA) for patients with ACC. PATIENTS AND METHODS: We reviewed the NCDB for patients undergoing surgical resection (MIA vs. OA) for ACC from 2010 to 2017. Inverse probability of treatment weighted logistic regression, negative binomial, and Cox proportional hazards models were fit to assess for an association of surgical approach with cumulative treatment burden (any adjuvant therapy, radiation therapy [RT], and systemic therapy), oncological effectiveness (positive surgical margins [PSM], lymph node yield [LNY], and overall survival [OS]), and perioperative morbidity (length of stay [LOS] and readmission) as appropriate. RESULTS: We identified 776 patients that underwent adrenalectomy for ACC, of which 307 underwent MIA. We noted patients with larger tumors (OR 0.82, 95% CI 0.78-0.86, P < .001) were less likely to have MIA prior to IPTW. We did not appreciate a significant association of MIA with cumulative treatment burden or the use of any adjuvant therapy (OR 0.85, 95% CI 0.60-1.21, P = .375), adjuvant RT (OR 0.94, 95% CI 0.59-1.50, P = .801), or adjuvant systemic therapy (OR 0.84, 95% CI 0.58-1.21, P = .352). Patients undergoing MIA had similar oncological effectiveness of surgery and OS when compared with patients which underwent OA. Patients that underwent MIA had a significantly shorter LOS (IRR: 0.74, 95% CI 0.62-0.88, P = .001) and lower odds of readmission (OR 0.46, 95% CI 0.23-0.91, P = .026). CONCLUSIONS: Although the standard of care for adrenal lesions suspicious for ACC remains OA, in appropriately selected patients, MIA may offer similar oncological effectiveness and cumulative treatment burden, with less morbidity, than OA.

The Role of Cytoreductive Nephrectomy in Metastatic Renal Cell Carcinoma: A Real-World Multi-Institutional Analysis.

PURPOSE: The role of cytoreductive nephrectomy (CN) in metastatic renal cell carcinoma (mRCC) was challenged by the results of the CARMENA trial. Here we evaluate the role of CN in mRCC patients, including those receiving modern therapies. MATERIALS AND METHODS: We included patients with synchronous mRCC between 2011-2020 from the de-identified nationwide Flatiron Health database. We evaluated 3 groups: systemic therapy alone, CN followed by systemic therapy (up-front CN [uCN]) and systemic therapy followed by CN (deferred CN [dCN]). The primary outcome was median overall survival (mOS) in patients receiving systemic therapy alone vs uCN. Secondary outcome was overall survival in patients receiving uCN vs dCN. First-treatment, landmark and time-varying covariate analyses were conducted to overcome immortal time bias. Weighted Kaplan-Meier curves, log-rank tests and Cox proportional hazards regressions were used to assess the effect of therapy on survival. RESULTS: Of 1,910 patients with mRCC, 972 (57%) received systemic therapy, 605 (32%) received uCN, 142 (8%) dCN and 191 (10%) CN alone; 433 (23%) patients received immunotherapy-based therapy. The adjusted mOS was significantly improved in first-treatment, landmark and time-varying covariate analysis (mOS 26.6 vs 14.6 months, 36.3 vs 21.1 months and 26.1 vs 12.2 months, respectively) in patients undergoing CN. Among patients receiving CN and systemic therapy, the timing of systemic therapy relative to CN was not significantly related to overall survival (HR=1.0, 95% CI 0.76-1.32, p=0.99). CONCLUSIONS: Our findings support an oncologic role for CN in select mRCC patients. In patients receiving both CN and systemic therapy, the survival benefit compared to systemic alone was similar for up-front and deferred CN.

Oncologic Outcomes of cT1 and cT2 Micropapillary Variant Compared with cT1 and cT2 Conventional Urothelial Carcinoma Treated with Radical Cystectomy.

INTRODUCTION: Our objective was to estimate the difference in outcomes for patients with clinical T stage 1 (cT1) and 2 (cT2) micropapillary (MPBC) and urothelial carcinoma (UCBC) bladder cancer treated with radical cystectomy (RC). METHODS: We reviewed the National Cancer Database for patients with cT1/2N0M0 MPBC and UCBC treated with RC from 2004-2016. Patients were classified by cT stage and histology. Outcomes of interest included upstaging to advanced pathological stage (pT3/4), pathologically node positive disease (pN+), and overall survival (OS). The Kaplan-Meier method was used to estimate 5-year OS probability. Multivariable logistic regression models were fit to test for an association between cT stage and histology with outcomes. RESULTS: We identified 23,871 patients, of whom 384 had MPBC and 23,487 had UCBC. More patients with cT1 and cT2 MPBC had advanced pathological stage and pN+ (cT1: 31% and 34%; cT2: 44% and 60%, respectively) compared with cT1 and cT2 UCBC (cT1: 18% and 14%; cT2: 27% and 24%, respectively). Compared with cT2 UCBC, patients with cT1 MPBC had similar odds of advanced pathological stage (OR: 0.96, 95% CI: 0.63-1.45, p=0.837) and increased odds of pN+ (OR: 1.62, 95% CI: 1.03-2.56, p=0.038). Five-year OS estimates for cT1 MPBC and UCBC were similar (58% and 60%, respectively) while cT2 MPBC had worse OS than cT2 UCBC (33% and 45%, respectively). CONCLUSIONS: In a cohort of patients undergoing RC, cT1/2 MPBC had worse outcomes than cT1/2 UCBC. Patients and surgeons should consider aggressive therapies for patients with cT1 MPBC due to the risk of inferior outcomes associated with cT2 MPBC disease.

Safety of neoadjuvant chemotherapy in patients with muscle-invasive bladder cancer and malignant ureteric obstruction.

OBJECTIVES: To determine whether patients with carcinoma invading bladder muscle (MIBC) and ureteric obstruction can safely receive cisplatin-based neoadjuvant chemotherapy (C-NAC), and to determine whether such patients require relief of obstruction with a ureteric stent or percutaneous nephrostomy prior to beginning C-NAC. PATIENTS AND METHODS: We performed a single-institution retrospective analysis of MIBC patients receiving C-NAC and falling into three groups: no ureteric obstruction (NO); relieved ureteric obstruction (RO); and unrelieved ureteric obstruction (URO). To address whether patients with obstruction can safely receive C-NAC, we compared patients with NO to those with RO, with the primary outcome of premature chemotherapy discontinuation. To investigate whether patients with obstruction should have the obstruction relieved prior to NAC, we compared RO to URO patients using a primary composite outcome of grade ≥ 3 adverse events, premature chemotherapy discontinuation, dose reduction, or dose interruption. The primary outcomes were compared using multivariable logistic regression. Sensitivity analyses were performed for the RO vs URO comparison, in which patients with only mild degrees of obstruction were excluded from the URO group. RESULTS: A total of 193 patients with NO, 49 with RO, and 35 with URO were analysed. There were no statistically significant differences between those with NO and those with RO in chemotherapy discontinuation (15% vs 22%; P = 0.3) or any secondary outcome. There was no statistically significant difference between those with RO and URO in the primary composite outcome (51% vs 53%; P = 1) or any secondary outcome. CONCLUSION: Patients with ureteric obstruction can safely receive C-NAC. Relief of obstruction was not associated with increased safety of C-NAC delivery.

Harnessing choice architecture in urologic practice: Implementation of an opioid-sparing protocol grounded in cognitive behavioral theory.

PURPOSE: Opioids are prescribed excessively following surgery. As many urologic oncology procedures are performed minimally invasively, an opportunity exists to push forward initiatives to minimize postoperative opioid use. MATERIALS AND METHODS: A quality improvement initiative to reduce inpatient opioid prescribing was launched at a tertiary cancer center. In Phase I (December 2019-July 2020), providers were instructed to start standing acetaminophen. In Phase II (beginning August 2020), education was provided to the entire care team and ordersets were modified to an opioid sparing protocol (OSP). We analyzed the proportion of minimally invasive surgery (MIS) prostatectomy and nephrectomy patients that adhered to an OSP during each phase and compared them to controls from the preceding 2 years. RESULTS: A total of 303, 153, and 839 patients underwent MIS during the Phase I, Phase II, and control periods respectively. The proportion of patients adhering to an OSP increased from 16% at the beginning of Phase I to 76% at the end of Phase II (p-trend < 0.001). The median total oral morphine equivalents for oral opioids declined from 20 mg and 40 mg at baseline for prostatectomy and nephrectomy patients respectively to 0 mg for both groups (p-trends < 0.001). Multivariable analysis found that patients received 22% and 81% less oral morphine equivalents during Phase I and II respectively compared to the control period (P < 0.001). CONCLUSIONS: Adherence to an OSP is most effective when initiatives incorporate the entire team and are supported by nudge theory-based structural changes. Using these strategies, most patients following urologic MIS can dramatically reduce opioid use postoperatively.

Systemic antifungal therapy with isavuconazonium sulfate or other agents in adults with invasive mucormycosis or invasive aspergillosis (non-fumigatus): A multicentre, non-interventional registry study.

BACKGROUND: Isavuconazole, administered as isavuconazonium sulfate (ISAVUSULF), is a broad-spectrum triazole agent for the treatment of invasive fungal disease. In phase 3 studies, ISAVUSULF showed comparable efficacy to voriconazole and amphotericin B for the treatment of invasive aspergillosis (IA) and invasive mucormycosis (IM), respectively. OBJECTIVES: The objective of this study is to determine all-cause mortality and safety outcomes among adults with IM and/or IA non-fumigatus (nf) treated with ISAVUSULF or other antifungal therapies (AFT). PATIENTS AND METHODS: This multicentre, non-interventional registry enrolled patients aged ≥18 years with IM or IA-nf who received systemic AFT from January 2016 to November 2018. Patients received primary ISAVUSULF, non-primary ISAVUSULF, or other AFT, as monotherapy or combination therapy. The primary end point was all-cause mortality at Days 42 and 84; safety outcomes were adverse drug reactions (ADRs) to ISAVUSULF. RESULTS: Of 204 patients enrolled, 74 received primary ISAVUSULF, 30 non-primary ISAVUSULF, and 100 other AFT. All-cause mortality through Day 42 was numerically lower in the non-primary ISAVUSULF group than in the primary ISAVUSULF and other AFT groups, for patients with IM (20.0% vs. 33.3% and 41.3%, respectively) or IA-nf (0% vs. 14.8% and 17.8%, respectively). All-cause mortality tended to be lower with combination therapy than with monotherapy, except for patients with IM receiving primary ISAVUSULF. Of 111 patients receiving ISAVUSULF, 14 (12.6%) reported ADRs, of whom three (2.7%) developed serious ADRs. There were no drug-related deaths. CONCLUSIONS: This study supports the effectiveness and tolerability of ISAVUSULF in clinical practice. Further research is required to confirm the value of ISAVUSULF combination therapy over monotherapy.

Patient Perceptions of Cardiac Electrophysiology Procedural Postponement at an Urban Center During the SARS-CoV-2 Pandemic.

To curb transmission of SARS-CoV-2 and preserve hospital resources, elective procedures were postponed in the United States, affecting patients previously scheduled for electrophysiology (EP) procedures. We aimed to understand patients' perceptions related to procedural postponements during the first wave of the SARS-CoV-2 pandemic. We performed a telephone survey between May 1-15 2020, of consecutive patients who experienced procedural postponement from March-April. Of 112 patients, 20% may have been lost to follow up and 12% lost interest in having their procedures done. The level of anxiety related to postponement was moderate to high in more than two thirds of patients.
