Background: Neuroendocrine carcinoma of the bladder (NEC-bladder) is a rare disease with poor outcomes and variable treatment approaches., Materials and Methods: Patients with localized NEC-bladder treated with surgery or radiation between 2001-2021 were retrospectively identified. Rates of pathologic complete response (pCR) and downstaging were evaluated following NAC in surgically-treated patients. Progression-free survival (PFS) and overall survival (OS) were analyzed with univariable (log-rank) and multivariable (MVA; Cox regression) methods., Results: Sixty-five patients were identified having a median age of 73. The tumor histology distribution was small cell (64.6%) or urothelial with NE differentiation (35.4%). Most patients (69.2%) received NAC. Patients received local therapy by surgery (78.5%) or chemoradiation (21.5%). The majority (62.7%) of surgical patients had ≥ pT2 with 37.3% having nodal involvement (pN+). The pCR and downstaging rates were 21.6% and 35.1%, respectively. At a median follow-up of 60 months (m), the median PFS and OS were 16.4m and 25.9m, respectively. NAC improved PFS (p=0.04) and downstaging improved PFS (p=0.012) and OS (p<0.001). Patients receiving NAC with ypN0 vs. ypN+ had median OS of 69.9m vs 15.3m, respectively (p<0.001). MVA identified receipt of NAC and pN as predictors of PFS; pN was predictive of OS. No differences in PFS or OS were seen between histology of primary tumor. The brain metastasis rate was 10.8% with all patients having small cell histology., Conclusions: Optimized therapy in NEC-bladder includes NAC followed by local consolidation. Ascertainment of ypN0 is associated with long term survival, while pN+ remains associated with poor outcomes., Competing Interests: Disclosure Austin Sim: leadership role (ASTRO non-voting member board of directors).

Background and Objective: There are limited data on the prevalence and management of testicular germ cell tumor (TGCT) cases presenting with venous tumor thrombus (VTT). Our objectives were to describe the prevalence of TGCT with VTT, to identify a multicenter retrospective cohort, and to ascertain expert opinion regarding optimal management of this entity., Methods: Using the IBM Marketscan database, we identified men with testicular cancer who underwent retroperitoneal lymph node dissection (RPLND) with concurrent VTT or inferior vena cava (IVC) tumor thrombectomy to estimate the prevalence of VTT in TGCT. To identify a multicenter retrospective cohort of patients, we surveyed surgeons and described the presentation, management, and outcomes for the cohort., Key Findings and Limitations: The prevalence of TGCT with VTT in the IBM Marketscan database was 0.3% (n = 7/2517) when using stringent criteria and 3.1% (n = 79/2517) when using broad criteria. In response to our survey, 16 surgeons from ten centers contributed data for 34 patients. Most patients (n = 29, 85%) presented with nonseminomatous germ cell tumor. Surgical management was used for 93.9% (n = 31), including postchemotherapy tumor thrombectomy with primary cavorrhaphy in 63%. The Marketscan analysis was limited to insured individuals and did not include clinicopathological details, and use of billing codes may have included patients with stromal tumors. In addition, lack of responses to the anonymous survey limited data capture, and the RedCap survey did not address symptoms specific to IVC obstruction or allow central review of the imaging leading to VTT diagnosis., Conclusions and Clinical Implications: VTT among males with TGCT is rare and requires complex multidisciplinary management, including venous tumor thrombectomy at the time of postchemotherapy RPLND., Patient Summary: Using a medical database, we estimated that the frequency of testicular cancer cases in which the tumor extends into a blood vessel (called venous tumor thrombus, VTT) is just 0.3-3.1%. We carried out a survey of surgeons with experience of this condition. Our results indicate that although testicular cancers respond well to chemotherapy, VTT is less responsive and complex surgery is necessary for this rare condition., (Copyright © 2024 European Association of Urology.

Purpose of Review: This review sought to define the emerging roles of urinary tumor DNA (utDNA) for diagnosis, monitoring, and treatment of bladder cancer. Building from early landmark studies the focus is on recent studies, highlighting how utDNA could aid personalized care., Recent Findings: Recent research underscores the potential for utDNA to be the premiere biomarker in bladder cancer due to the constant interface between urine and tumor. Many studies find utDNA to be more informative than other biomarkers in bladder cancer, especially in early stages of disease. Points of emphasis include superior sensitivity over traditional urine cytology, broad genomic and epigenetic insights, and the potential for non-invasive, real-time analysis of tumor biology. utDNA shows promise for improving all phases of bladder cancer care, paving the way for personalized treatment strategies. Building from current research, future comprehensive clinical trials will validate utDNA's clinical utility, potentially revolutionizing bladder cancer management., (© 2024.

What Is This Summary About?: This is a summary of two studies that looked at the safety and effectiveness of a potential new treatment, N-803 (Anktiva), in combination with a standard treatment bacillus Calmette-Guerin (BCG) for people with non-muscle invasive bladder cancer (NMIBC) .One study was a Phase 1b study that tested increasing doses of N-803 in combination with the same dose of BCG in people with NMIBC who had never received BCG previously (BCG-naive). The other study is a Phase 2/3 study of N-803 and BCG in people with NMIBC whose cancer wasn't eliminated by BCG alone (BCGunresponsive)., What Happened in the Studies?: In the Phase 1b study, the nine participants were split into three groups of 3 participants who received a dose of 100, 200, or 400 μg N-803 along with a standard 50 mg dose of BCG. In the Phase 2/3 study, one group (cohort A) of participants with carcinoma in situ (CIS) disease and another group (cohort B) with papillary disease were treated with 400 μg N-803 plus 50 mg BCG. There was also a cohort C that received only 400 μg N-803. Treatments were delivered directly into the bladder once a week for 6 weeks in a row., What Were the Key Takeaways?: N-803 plus BCG eliminated NMIBC in all nine BCG-naive participants and the effects were long-lasting, with participants remaining NMIBC-free for a range of 8.3 to 9.2 years.As reported in 2022, cancer was eliminated in 58 of 82 (71%) participants with BCG-unresponsive CIS disease and the effect was also long-lasting. Importantly, approximately 90% of the successfully treated participants avoided surgical removal of the bladder. In cohort B participants with papillary disease, 40 of 72 (55.4%) were cancer-free 12 months after treatment. N-803 used alone was only effective in 2 of 10 participants. In both studies, the combination of N-803 and BCG was found to be associated with very few adverse events.Based on results from the Phase 2/3 study, the U.S. Food and Drug Association (FDA) approved the use of N-803 plus BCG for the treatment of BCG-unresponsive bladder CIS with or without Ta/T1 papillary disease. Clinical Trial Registration: NCT02138734 (Phase 1b study), NCT03022825 (Phase 2/3 study).

Background: Recent progresses in the use of immune checkpoint inhibitor (ICI) have challenged the therapeutic standards in patients with muscle-invasive urothelial bladder carcinoma (MIBC)., Objective: To compare neoadjuvant pembrolizumab followed by radical cystectomy (RC) versus neoadjuvant chemotherapy (NAC) and RC or upfront RC, according to cisplatin eligibility., Design, Setting, and Participants: We conducted two separate analyses for cisplatin-eligible and cisplatin-ineligible cT2-4N0M0 MIBC patients. We used a propensity score adjustment that relied on inverse probability of treatment-weighting (IPTW)., Intervention: Pembrolizumab within the PURE-01 trial, and NAC and RC or upfront RC from a high-volume tertiary care referral center., Outcome Measurements and Statistical Analysis: The primary endpoint in both analyses was event-free survival (EFS), defined as freedom from recurrence, and/or death from any cause indexed from the date of treatment initiation or RC. The secondary endpoints included EFS in propensity score-matched patients, pathologic response rate, and recurrence-free survival (RFS) after RC., Results and Limitations: A total of 458 patients who underwent RC, with or without NAC, at Moffitt Cancer Center between October 2005 and October 2020, and 146 patients enrolled in PURE-01 were analyzed. In cisplatin-ineligible patients, EFS was superior in those receiving pembrolizumab (p < 0.001). The estimated 3-yr EFS was 77.8% (95% confidence interval [CI]: 63.5-95.2) for pembrolizumab and RC, and 36.1% (95% CI: 28.6-45.5) for upfront RC. EFS remained superior in those receiving neoadjuvant ICI (NICI) following IPTW (p < 0.001). In cisplatin-eligible patients, EFS was superior in those receiving pembrolizumab and RC (p < 0.001). The estimated 3-yr EFS was 86.9% (95% CI: 80.9-93.3) for pembrolizumab and 63.5% (95% CI: 56.5-71.4) for NAC. EFS remained superior in those receiving NICI following IPTW (p < 0.001). Pathologic responses and RFS in pembrolizumab-treated patients were also superior to those in NAC-treated patients. Results are limited by the retrospective nature of the study., Conclusions: In the first ever reported comprehensive comparison of outcomes between neoadjuvant ICI and NAC, followed by RC, or upfront RC, we report increased responses and improved oncologic outcomes with neoadjuvant ICI in patients with MIBC., Patient Summary: We compared the results obtained from the use of pembrolizumab and radical cystectomy with standard-of-care treatments in patients with bladder carcinoma infiltrating the muscle layer. We reported increased response and survival rates possibilities with the use of immunotherapy, anticipating the possibility to set new therapeutic standards in these patients, pending the results of ongoing randomized studies., (Copyright © 2023 European Association of Urology.

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.

Background: Careful patient selection is critical when considering cytoreductive nephrectomy (CN) for metastatic renal cell carcinoma (mRCC) but few studies have investigated the prognostic value of radiologic features that measure tumor burden., Objective: To develop a prognostic model to improve CN selection with integration of common radiologic features with known prognostic factors associated with mortality in the first year following surgery., Design, Settings, and Participants: Data were analyzed for consecutive patients with mRCC treated with upfront CN at five institutions from 2006 to 2017. Univariable and multivariable models were used to evaluate radiographic features and known risk factors for associations with overall survival. Relevant factors were used to create the SCREEN model and compared to the International mRCC Database Consortium (IMDC) model for predictive accuracy and clinical usefulness., Results and Limitations: A total of 914 patients with mRCC were treated with upfront CN during the study period. Seven independently predictive variables were used in the SCREEN score: three or more metastatic sites, total metastatic tumor burden ≥5 cm, bone metastasis, systemic symptoms, low serum hemoglobin, low serum albumin, and neutrophil/lymphocyte ratio ≥4. Predictive accuracy measured as the area under the receiver operating characteristic curves was 0.76 for the SCREEN score and 0.55 for the IMDC model. Decision curve analysis showed that the SCREEN model was useful beyond the IMDC classifier for threshold first-year mortality probabilities between 15% and 70%., Conclusions: The SCREEN score had higher predictive accuracy for first-year mortality compared to the IMDC scheme in a multi-institutional cohort and may be used to improve CN selection., Patient Summary: This study provides a model to improve selection of patients with metastatic kidney cancer who may benefit from surgical removal of the primary kidney tumor. We found that radiographic measurements of the tumor burden predicted the risk of death in the first year after surgery. The model can be used to improve decision-making by these patients and their physicians., (Copyright © 2023. Published by Elsevier B.V.)

Background: Optimal patient selection for neoadjuvant chemotherapy prior to surgical extirpation is limited by the inaccuracy of contemporary clinical staging methods in high-risk upper tract urothelial carcinoma (UTUC)., Objective: To investigate whether the detection of plasma circulating tumor DNA (ctDNA) can predict muscle-invasive (MI) and non-organ-confined (NOC) UTUC., Design, Setting, and Participants: Plasma cell-free DNA was prospectively collected from chemotherapy-naïve, high-risk UTUC patients undergoing surgical extirpation and sequenced using a 152-gene panel and low-pass whole-genome sequencing., Outcome Measurements and Statistical Analysis: To test for concordance, whole-exome sequencing was performed on matching tumor samples. The performance of ctDNA for predicting MI/NOC UTUC was summarized using the area under a receiver-operating curve, and a variant count threshold for predicting MI/NOC disease was determined by maximizing Youden's J statistic. Kaplan-Meier methods estimated survival, and Mantel-Cox log-rank testing assessed the association between preoperative ctDNA positivity and clinical outcomes., Results and Limitations: Of 30 patients enrolled prospectively, 14 were found to have MI/NOC UTUC. At least one ctDNA variant was detected from 21/30 (70%) patients, with 52% concordance with matching tumor samples. Detection of at least two panel-based molecular alterations yielded 71% sensitivity at 94% specificity to predict MI/NOC UTUC. Imposing this threshold in combination with a plasma copy number burden score of >6.5 increased sensitivity to 79% at 94% specificity. Furthermore, the presence of ctDNA was strongly prognostic for progression-free survival (PFS; 1-yr PFS 69% vs 100%, p < 0.001) and cancer-specific survival (CSS; 1-yr CSS 56% vs 100%, p = 0.016)., Conclusions: The detection of plasma ctDNA prior to extirpative surgery was highly predictive of MI/NOC UTUC and strongly prognostic of PFS and CSS. Preoperative ctDNA demonstrates promise as a biomarker for selecting patients to undergo neoadjuvant chemotherapy prior to nephroureterectomy., Patient Summary: Here, we show that DNA from upper tract urothelial tumors can be detected in the blood prior to surgical removal of the kidney or ureter. This circulating tumor DNA can be used to predict that upper tract urothelial carcinoma is invasive into the muscular lining of the urinary tract and may help identify those patients who could benefit from chemotherapy prior to surgery., (Copyright © 2023 European Association of Urology.

Objective: UGN-101 has been approved for the chemoablation of low-grade upper tract urothelial cancer (UTUC) involving the renal pelvis and calyces. Herein is the first reported cohort of patients with ureteral tumors treated with UGN-101., Patients and Methods: We performed a retrospective review of patients treated with UGN-101 for UTUC at 15 high-volume academic and community centers focusing on outcomes of patients treated for ureteral disease. Patients received UGN-101 with either adjuvant or chemo-ablative intent. Response rates are reported for patients receiving chemo-ablative intent. Adverse outcomes were characterized with a focus on the rate of ureteral stenosis., Results: In a cohort of 132 patients and 136 renal units, 47 cases had tumor involvement of the ureter, with 12 cases of ureteral tumor only (8.8%) and 35 cases of ureteral plus renal pelvic tumors (25.7%). Of the 23 patients with ureteral involvement who received UGN-101 induction with chemo-ablative intent, the complete response was 47.8%, which did not differ significantly from outcomes in patients without ureteral involvement. Fourteen patients (37.8%) with ureteral tumors had significant ureteral stenosis at first post-treatment evaluation, however, when excluding those with pre-existing hydronephrosis or ureteral stenosis, only 5.4% of patients developed new clinically significant stenosis., Conclusions: UGN-101 appears to be safe and may have similar efficacy in treating low-grade urothelial carcinoma of the ureter as compared to renal pelvic tumors., Competing Interests: Declaration of Competing Interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Solomon Woldu receives honoraria for consulting for UroGen Pharma Ltd.

Objective: To evaluate factors associated with perioperative outcomes in a multi-institutional cohort of patients treated with cytoreductive nephrectomy (CN)., Methods: Data were analyzed for metastatic renal cell carcinoma patients treated with CN at 6 tertiary academic centers from 2005 to 2019. Outcomes included: Clavien-Dindo complications, mortality, length of hospitalization, 30-day readmission rate, and time to systemic therapy. Univariate and multivariable models evaluated associations between outcomes and prognostic variables including the year of surgery., Results: A total of 1272 consecutive patients were treated with CN. Patients treated in 2015-2019 vs 2005-2009 had better performance status (P<.001), higher pathologic N stage (P = .04), more frequent lymph node dissections (P<.001), and less frequent presurgical therapy (P = .02). Patients treated in 2015-2019 vs 2005-2009 had lower overall and major complications from surgery, 22% vs 39%, P<.001% and 10% vs 16%, P = .03. Mortality at 90days was higher for patients treated 2005-2009 vs 2015-2019; 10% vs 5%, P = .02. After multivariable analysis, surgical time period was an independent predictor of major complications and 90-day mortality following cytoreductive surgery., Conclusion: Postoperative major complications and mortality rates following CN are significantly lower in patients treated within the most recent time period., Competing Interests: Declaration of Competing Interest The authors have no conflict of interest to declare., (Copyright © 2023.

Purpose: No consensus exists on the management of men with nonseminoma and viable nonteratomatous germ cell tumor in the postchemotherapy retroperitoneal lymph node dissection (pcRPLND) specimen after first-line chemotherapy. We analyzed surveillance versus different adjuvant chemotherapy regimens and the influence of time to pcRPLND on oncologic outcomes., Methods: Data on 117 men treated with cisplatin-based first-line chemotherapy between 1990 and 2018 were collected from 13 institutions. All patients had viable nonteratomatous germ cell tumor in the pcRPLND specimen. Surgery was performed after a median of 57 days, followed by either surveillance (n = 64) or adjuvant chemotherapy (n = 53). Primary end points were progression-free survival (PFS), cancer-specific survival (CSS), and overall survival (OS)., Results: After controlling for International Germ Cell Cancer Cooperative Group risk group and percent of viable malignant cells found at RPLND, no difference was observed between men managed with surveillance or adjuvant chemotherapy regarding PFS (hazard ratio [HR], 0.72 [95% CI, 0.32 to 1.6]; P = .4), CSS (HR, 0.69; 95% CI, 0.20 to 2.39; P = .6), and OS (HR, 0.78 [95% CI, 0.25 to 2.44]; P = .7). No statistically significant differences for PFS, CSS, or OS were observed on the basis of chemotherapy regimen or in men treated with pcRPLND ≤57 versus >57 days after first-line chemotherapy. Residual disease with <10% versus ≥10% viable cancer cells were associated with a longer PFS (HR, 3.22 [95% CI, 1.29 to 8]; P = .012). Relapse in the retroperitoneum was observed in 34 (29%) men., Conclusion: Men with a complete resection at pcRPLND and <10% viable cells have favorable outcomes without further treatment. Complete retroperitoneal resection seems more important than early pcRPLND.

Background: Despite abundant evidence supporting the use of perioperative chemotherapy from clinical trials, no study to date has comprehensively evaluated its use in the treatment of muscle-invasive bladder cancer (MIBC) in the real-world setting. Little is known regarding the impact of pretreatment disease stage and real-world factors such as patient comorbidities preventing timely completion of therapy on its effectiveness. This study aims to assess the usage of perioperative chemotherapy and examines its impact on pathologic downstaging rates and recurrence free survival in patients undergoing radical cystectomy., Methods: A retrospective review was conducted in 805 patients with muscle invasive bladder cancer undergoing radical cystectomy with no perioperative chemotherapy, 761 with presurgical chemotherapy followed by radical cystectomy, and 134 radical cystectomy followed by adjuvant chemotherapy. Relevant clinicopathologic features were reviewed. Recurrence-free survival and Overall Survival probability estimates were calculated using the Kaplan-Meier method and compared using the Log-rank or Gehan-Breslow tests. The prognostic effects of presurgical chemotherapy and adjuvant chemotherapy regimens were evaluated by estimating hazard ratio and 95% confidence interval from an adjusted Cox proportional hazards model. Statistical tests were 2-sided, and significance was defined as P-value < 0.05., Results: In this contemporary, real-world cohort, 5-yr RFS was found to be 65.6% in pT0, 59.1%in pT2, and 10.8% in pN+ patients. Presurgical chemotherapy increased pathologic downstaging rates from 27.5% to 41.1% in patients with ≥cT2 BCa. Stratified by clinical T-stage, only cT2 patients derived recurrence-free survival (Median 45.3 months vs. 29.0 months, P < 0.01) and overall survival (Median 62.3 months vs. 41.9 months, P < 0.001) benefits.  In patients with adverse pathologic features (≥pT3 or pN+), adjuvant chemotherapy improved recurrence-free survival (Median 22.8 months vs. 10.0 months, P < 0.0001) and overall survival (Median OS 32.4 months vs. 16.3 months, P < 0.0001)., Conclusions: We report real-world outcomes from a large cohort of muscle-invasive bladder cancer patients undergoing surgical treatment with/out perioperative chemotherapy. Pathologic response rates to pre-surgical chemotherapy were modest and led to clinical benefit only in cT2 patients. Adjuvant chemotherapy provided survival benefit for pathologically advanced MIBC patients irrespective of pT/N staging., Competing Interests: Declaration of Competing Interest There are no conflicts of interest pertaining to this study.

Purpose: Immune checkpoint blockade holds promise for treating bacillus Calmette-Guerin (BCG)-unresponsive non-muscle-invasive bladder cancer (NMIBC). In this phase II study, we investigated the safety and efficacy of durvalumab, a human IgG1 monoclonal antibody, against BCG-unresponsive carcinoma in situ (CIS)., Patients and Methods: Patients with BCG-unresponsive CIS-containing NMIBC received durvalumab IV at 1,500 mg every 4 weeks for up to 12 months. The primary endpoint was complete response (CR) rate at month 6, defined by negative cystoscopy, urine cytology, and absence of high-grade recurrence on bladder mapping biopsy. The null hypothesis specified a CR rate of 18% and alternative hypothesis of 40%. According to the Simon two-stage design, if ≤3/13 patients achieved CR during stage 1, the trial is stopped due to futility., Results: Between March 8, 2017, and January 24, 2020, 17 patients were accrued whereas 4 withdrew from study treatment after bladder biopsy at month 3 was positive for CIS. Two of 17 (12%) achieved a CR at month 6, with duration of response of 10 and 18 months, respectively. A single grade 3 lipase elevation was attributed to durvalumab, and immune-related adverse events were observed in 7/17 (41%) patients. Only 1/17 patients had high programmed death-ligand 1 expression pretreatment. On RNA sequencing, complement activation genes were elevated posttreatment, along with enrichment of tumor-associated macrophage signature., Conclusions: Durvalumab monotherapy conferred minimal efficacy in treating BCG-unresponsive CIS of the bladder, with 6-month CR of 12%. Complement activation is a potential mechanism behind treatment resistance., (©2023 American Association for Cancer Research.)

Background: Intracavitary UGN-101 is approved for the treatment of low-grade noninvasive upper tract urothelial carcinoma (UTUC). Post-commercialization studies underscore the benefit of UGN-101 administration for patients with imperative indications for whom radical nephroureterectomy (RNU) is not a viable option., Objective: To describe the use, efficacy, and safety of UGN-101 in patients with UTUC with imperative indications for renal preservation, including high-grade disease., Design, Setting, and Participants: Patients receiving UGN-101 with imperative indications were retrospectively analyzed using a multicenter centralized registry from 15 high-volume academic and community centers., Outcome Measurements and Statistical Analysis: We defined imperative indications as patients with a solitary kidney, the presence of chronic kidney disease (CKD) with a glomerular filtration rate <30 ml/min, bilateral UTUC, and patients unfit for or unwilling to undergo surgical extirpation. Tumor characteristics, disease progression/recurrence, and adverse events were recorded on a per-renal-unit basis., Results and Limitations: UGN-101 was instilled into 52 renal units (38%) in 48 patients for imperative indications, including 29 patients (56%) with a solitary kidney, 11 kidneys (21%) in the setting of bilateral UTUC, six patients (12%) with CKD, and six patients (12%) who were unfit for or unwilling to undergo RNU. Twelve renal units had biopsy-proven high-grade papillary disease. Tumors were completely ablated before induction therapy in 34% of cases, while 66% had tumor present. Following induction therapy, 17 patients (40%) had no evidence of disease (NED) on ureteroscopy, 88% of whom maintained this status at median follow-up of 10.8 mo. In the cohort with high-grade disease, five patients (45%) had NED at initial post-induction primary disease evaluation. Adverse events included pyelonephritis (8%), ureteral stenosis (8%), anemia (6%), and acute renal failure (4%). Limitations include the retrospective study design, the lack of long-term follow up, and patient selection bias., Conclusions: Intracavitary therapy with UGN-101 in patients with UTUC and imperative indications shows promise as a kidney-sparing treatment modality. While long-term follow-up is needed, this intracavitary treatment may help in prolonging time to RNU and delaying the morbidity of hemodialysis in this comorbid population., Patient Summary: We reviewed results for patients with cancer in the upper urinary tract and an additional condition that would not allow kidney removal who received treatment with a gel called UGN-101. Our results suggest that UGN-101 shows promise as a kidney-sparing treatment. It may delay the time until kidney removal is needed in these patients and avoid the negative effects associated with dialysis., (Copyright © 2023 European Association of Urology.

Objective: Guideline recommendations disagree on template boundaries for pelvic lymph node dissection (PLND) in conventional urothelial carcinoma. Less is known about PLND in variant histology. We aimed to analyze the role of LND in plasmacytoid urothelial carcinoma (PUC)., Methods: A retrospective review of patients with cTanyNanyM0 PUC who underwent radical cystectomy (RC) with PLND was performed from 2012 to 2022. Lymph node count (LNC) was a surrogate for extent of lymph node dissection and dichotomized based on maximally selected rank statistics. Multivariable cox hazard regression analysis (MVA) for overall survival (OS) corrected for age, perioperative chemotherapy, soft tissue margin status, and stage ≥pT3 and/or pN+ was performed. Disease free survival (DFS) and OS were estimated using Kaplan-Meier (KM) analysis., Results: Sixty-seven patients with median age of 71, who were 79.1% male were included. Neoadjuvant and adjuvant chemotherapy were administered in 61.2% and 19.4% of patients, respectively. At RC, 70.1% were ≥pT3. Median LNC was 22 (IQR 14-27) with 43.3% of patients being pN+. Calculated optimal-LNC cut point for DFS and OS was 19. Grouping by optimal (≥20) vs. suboptimal-LNC (<20), no significant clinicodemographic differences were found. Optimal-LNC provided improved DFS (P = 0.05) and OS (P = 0.02). Optimal-LNC (HR 0.47, 0.24-0.93 CI 95%, P = 0.03) and negative soft tissue margin (HR 0.38, 0.19-0.76 CI 95%, P = 0.01) was associated with improved OS on MVA. Receipt of perioperative chemotherapy did not improve OS (P = 0.46)., Conclusion: In PUC, complete surgical extirpation achieving negative soft tissue margins and removing ≥20 lymph should be prioritized if operative intervention is pursued., (Copyright © 2023 Elsevier Inc.

Objectives: To assess the safety profile of antegrade mitomycin gel instillation through a percutaneous nephrostomy tube (PCNT) for upper tract urothelial carcinoma (UTUC) with the aim of decreasing morbidity associated with therapy., Patients and Methods: Patients undergoing antegrade administration of mitomycin gel via PCNT were retrospectively included for analysis from four tertiary referral centres between 2020 and 2022. The primary outcome was safety profile, as graded by Common Terminology Criteria for Adverse Events (v5.0). Post-therapy disease burden was assessed by primary disease evaluation (PDE) via ureteroscopy., Results: Thirty-two patients received at least one dose of mitomycin gel via PCNT for UTUC, 29 of whom completed induction and underwent PDE. Thirteen patients (41%) had residual tumour present prior to induction therapy. At a median of 15.0 months following first dose of induction therapy, ureteric stenosis occurred in three patients (9%), all of whom were treated without later recurrence or chronic stenosis. Other adverse events included fatigue (27%), flank pain (19%), urinary tract infection (12%), sepsis (8%) and haematuria (8%). No patients had impaired renal function during follow-up and there were no treatment-related deaths. Seventeen patients (59%) had no evidence of disease at PDE and have not experienced recurrence at a median follow-up of 13.0 months post induction., Conclusions: Administration of mitomycin gel via a PCNT offers a low rate of ureteric stenosis, demonstrates a favourable safety profile, and is administered without general anaesthesia., (© 2022 The Authors.

The urologic oncology patient who refuses blood transfusion can present unique challenges in perioperative blood management. Since blood loss and associated transfusion can be expected in many complex urologic oncology surgeries, a multidisciplinary approach may be required for optimal outcomes. Through collaboration with the hematologist, anesthesiologist, and urologist, various techniques can be employed in the perioperative phases to minimize blood loss and the need for transfusion. We review the risks and benefits of these techniques and offer recommendations specific to the urologic oncology patient., (Copyright © 2022 Elsevier Inc. All rights reserved.)

Introduction and Objective: Muscle invasive bladder cancer with extravesical extension is an aggressive disease entity that requires multimodal therapy. The benefits of adjuvant chemotherapy (AC) in patients with a positive soft-tissue surgical margin (STSM), however, are relatively unknown due to exclusion of this population in randomized controlled trials of AC. We sought to define survival benefits in this patient population through our institutional bladder cancer database., Methods: Retrospective review of all patients undergoing radical cystectomy for urothelial carcinoma of the bladder from 2004-2020 with ≥pT3b disease irrespective of neoadjuvant chemotherapy (NAC) use was conducted. Progression-free survival (PFS) and overall survival (OS) estimates were obtained using the Kaplan-Meier method with log-rank test, and the Cox-proportional hazards model was used to identify predictors of improved PFS and OS. AC was defined by any chemotherapy use within 90 days of cystectomy, regardless of STSM status., Results: 476 patients with pT3b disease or worse were identified. Median follow-up was 12.3 months. An amount of 21% of patients were treated with AC. An amount of 24% of patients had positive STSM. Median OS for patients with positive STSM was 8.4 months [95% CI 7-11.5] and 18.3 months [95% CI 15.6-20.8] ( p < 0.001) for patients with negative STSM. In the overall cohort, positive STSM (HR 1.93, 95% CI 1.45-2.57, p < 0.001), AC use (HR 0.68, 95% CI 0.51-0.90, p = 0.007), and pN1-3 disease (HR 1.47, 95% CI 1.16-1.87, p = 0.002) were independent predictors of OS when adjusted for performance status, pT-stage, and neoadjuvant chemotherapy use. In patients with positive STSM, median survival was seven months [95% CI 5.2-8.4] without AC, compared to 16.2 months [95% CI 11.5-52.5] with AC ( p = 0.0038). For patients with negative STSM, median survival was 17.4 months [95% CI 14-20.1] without AC compared to 22.3 months [95% CI 17.2-36.9] with AC ( p = 0.23). In patients with positive STSM, AC use was the only factor associated with an OS benefit with a HR of 0.41 (95% CI 0.21-0.78, p = 0.007). In patients with negative STSM, pT4 and pN1-3 disease were the only factors associated with worse overall survival with a HR of 1.32 (95% CI 1.00-1.74, p = 0.050) and 1.97 (95% CI 1.49-2.60, p < 0.001), respectively., Conclusions: Administration of adjuvant chemotherapy is of particular benefit in patients with positive STSM following radical cystectomy for gross extravesical disease. Positive STSM may be a representative of "early metastatic" or micrometastatic disease.

Patients with metastatic renal cell cancer (mRCC) who respond to upfront immune checkpoint inhibitor (ICI) combination therapies may be treated with cytoreductive nephrectomy (CN) to remove radiographically viable primary tumors. Early data for post-ICI CN suggested that ICI therapies induce desmoplastic reactions in some patients, increasing the risk of surgical complications and perioperative mortality. We evaluated perioperative outcomes for 75 consecutive patients treated with post-ICI CN at four institutions from 2017 to 2022. Our cohort of 75 patients had minimal or no residual metastatic disease but radiographically enhancing primary tumors after ICI and were treated with CN. Intraoperative complications were identified in 3/75 patients (4%) and 90-d postoperative complications in 19/75 (25%), including two patients (3%) with high-grade (Clavien ≥III) complications. One patient was readmitted within 30 d. No patients died within 90 d after surgery. Viable tumor was present in all but one specimen. Approximately half of the patients (36/75, 48%) remained off systemic therapy at last follow-up. These data suggest that CN following ICI therapy is safe and associated with low rates of major postoperative complications in appropriately selected patients at experienced centers. Post-ICI CN may facilitate observation without additional systemic therapy in patients without significant residual metastatic disease., Patient Summary: Current first-line treatment for patients with kidney cancer that has spread to other sites (metastatic cancer) is immunotherapy. For cases in which metastatic sites respond to this therapy but primary tumor is still detected in the kidney, surgical treatment of the tumor is feasible and has a low rate of complications, and may delay the need for further chemotherapy., (© 2023 The Author(s).)

The COVID-19 public health emergency forced the conversion of in-person SUO fellowship interviews into virtual interviews. We sought to understand applicant perspectives and preferences related to virtual interviews and whether programs should consider virtual interviews in the future. We distributed a survey to 2020 SUO Fellowship interview participants at 4 SUO urologic oncology fellowship programs. Response items were on a Likert scale scored 1-5 with higher scores indicating greater agreement with the survey item construct. Survey responses were collated and thematic mapping used to describe open text responses. Descriptive statistics were used for analysis of survey and open text results. Fifty-eight SUO fellowship applicants completed the survey. Virtual interviews successfully promoted interaction with SUO fellowship program faculty (mean 4.6, SD 0.6), outlined program research opportunities (mean 4.5, SD 0.7), and proffered opportunities to ask questions about the fellowship (mean 4.7, SD 0.5). Applicants exhibited weakly positive orientation to the adequacy of the virtual format (mean 3.5, SD 1.1). 63% of applicants would prefer a virtual format in the future. Qualitative feedback noted the benefits of virtual interviews were lower cost and reduced time away from residency. SUO fellowship applicants exhibited mixed preferences for virtual and in-person interviews. Although virtual fellowship interviews have benefits such as cost savings and time efficiency, notable weaknesses included challenges observing the culture of the programs. Following the pandemic, SUO fellowship programs may consider virtual interviews but should consider incorporating opportunities for informal interactions between faculty, fellows, and fellow applicants., (Copyright © 2021 Elsevier Inc.

BACKGROUND: Patients with Bacillus Calmette–Guérin (BCG)–unresponsive non–muscle-invasive bladder cancer (NMIBC) have limited treatment options. The immune cell–activating interleukin-15 (IL-15) superagonist Nogapendekin alfa inbakicept (NAI), also known as N-803, may act synergistically with BCG to elicit durable complete responses (CRs) in this patient population. METHODS: In this open-label, multicenter study, patients with BCG-unresponsive bladder carcinoma in situ (CIS) with or without Ta/T1 papillary disease were treated with intravesical NAI plus BCG (cohort A) or NAI alone (cohort C). Patients with BCG-unresponsive high-grade Ta/T1 papillary NMIBC also received NAI plus BCG (cohort B). The primary end point was the incidence of CR at the 3- or 6-month assessment visit for cohorts A and C, and the disease-free survival (DFS) rate at 12 months for cohort B. Durability, cystectomy avoidance, progression-free survival, disease-specific survival (DSS), and overall survival were secondary end points for cohort A. RESULTS: In cohort A, CR was achieved in 58 (71%) of 82 patients (95% confidence interval [CI]=59.6 to 80.3; median follow-up, 23.9 months), with a median duration of 26.6 months (95% CI=9.9 months to [upper bound not reached]). At 24 months in patients with CR, the Kaplan–Meier estimated probability of avoiding cystectomy and of DSS was 89.2% and 100%, respectively. In cohort B (n=72), the Kaplan–Meier estimated DFS rate was 55.4% (95% CI=42.0% to 66.8%) at 12 months, with median DFS of 19.3 months (95% CI=7.4 months to [upper bound not reached]). Most treatment-emergent adverse events for patients receiving BCG plus NAI were grade 1 to 2 (86%); three grade 3 immune-related treatment-emergent adverse events occurred. CONCLUSIONS: In patients with BCG-unresponsive bladder carcinoma in situ and papillary NMIBC treated with BCG and the novel agent NAI, CRs were achieved with a persistence of effect, cystectomy avoidance, and 100% bladder cancer–specific survival at 24 months. The study is ongoing, with an estimated target enrollment of 200 participants (Funded by ImmunityBio.)

Purpose: Because the optimal number of cycles of neoadjuvant gemcitabine and cisplatin chemotherapy (GC) is unclear, we aimed to compare disease response and survival outcomes of patients receiving either 3 or 4 cycles of neoadjuvant GC for muscle-invasive bladder cancer (MIBC)., Methods: A total of 166 patients who were treated with neoadjuvant GC and radical cystectomy for clinical stage T2-4N0M0 were identified. Response and effectiveness of different cycle counts were assessed using downstaging (complete pathologic and partial pathologic response), cancer-specific survival (CSS), and overall survival (OS). Response and survival outcomes were examined with adjusted logistic regression and Cox regression models. Statistical significance was defined as P < 0.05., Results: Of 166 patients who received neoadjuvant GC, 107 (64.5%) received 3 cycles and 59 (35.5%) received 4 cycles. Age, insurance, comorbidity, tumor histology (pure urothelial carcinoma, urothelial with divergent differentiation, variant histology), and tumor stage were similar between the 2 treatment groups. Rates of complete response or any downstaging were similar between groups (21.5% and 40.2% in the 3-cycle group and 20.3% and 44.1% in the 4-cycle group, respectively). While disease response was similar (OR 1.03, 95% CI 0.43-2.45), both cancer-specific survival (HR 1.69, 95% CI 0.87-3.26) and overall survival (HR:1.88, 95% CI:1.02-3.48) were more favorable among patients managed with 4 cycles of neoadjuvant chemotherapy compared to those who received 3 cycles in adjusted models., Conclusions: Our analysis demonstrated that survival outcomes tended to be better among patients who received 4 cycle of neoadjuvant GC compared to those treated with 3 cycles. Although potential benefits of omission of fourth cycle may include expedited time to surgery, reduced chemotherapy-associated toxicity, and lower treatment costs, continuation of treatment with a fourth cycle of neoadjuvant GC chemotherapy may benefit patients with muscle-invasive bladder cancer and further improve disease outcomes., Competing Interests: Conflict of Interest The authors declare no conflict of interest., (Copyright © 2022 Elsevier Inc.

Cancer testis antigens have been of interest as possible targets for cancer immunotherapies. To better understand the opportunities for the use of such immunotherapy targets, we used a chemical complementarity scoring algorithm and an original web tool to establish aspects of electrostatic complementarity of the CTAs, MAGEA3 and MAGEA6, with melanoma specimen resident, T-cell receptor (TCR) complementarity determining region 3 (CDR3) amino acid sequences. Greater electrostatic complementarity between T-cell receptor CDR3 and tumor CTAs MAGEA3/6 was associated with a greater probability of overall survival, for both the cancer genome atlas and Moffitt Cancer Center samples; and was associated with high levels of T-cell cytotoxicity-related gene expression. Most importantly, this approach allowed for the highly efficient screening of specific segments of the MAGEA3/6 antigens which indicated that certain MAGE segments would have either more or less risk of auto-reactivity. In sum, the chemical complementarity algorithm, and its efficient application via the web tool, adaptivematch.com, offers a convenient opportunity to identify likely parameters important for immunotherapy considerations and melanoma patient risk stratifications., Competing Interests: Conflict of interest statement Authors have nothing to declare., (Copyright © 2022 Elsevier Ltd.

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.

Purpose: Chylous ascites (CA) is an uncommon complication that occurs from traumatic disruption of lymphatic channels after retroperitoneal surgery. The purpose of this study was to generate an evidence-based management strategy for CA by reviewing the current literature and available treatment modalities., Materials and Methods: A MEDLINE® literature review was performed for "chylous ascites." Individual patient data were extracted from case series and reports to create an efficacy analysis. Treatment modality, drain output, time to escalation of care and time to resolution were recorded. The efficacy analysis was utilized to generate a data-driven treatment algorithm., Results: The literature review yielded 1,953 articles, from which 146 studies contributed data for 523 patients. The efficacy analysis included 245 patients, 168 (69%) of whom were managed successfully with conservative management (CM), at a median time to resolution of 11 days. Forty-eight patients underwent lymphangiography±embolization after CM, with a success rate of 85%. Thirty-one (12%) patients underwent surgical exploration. When treating CA, the patients who underwent stepwise management with CM followed by lymphangiography if CM failed experienced a resolution rate of 96.7%. An evidence-based treatment algorithm was created to guide treatment selection and duration of therapy before escalating to additional forms of therapy., Conclusions: In this report, we describe the largest conglomeration of iatrogenic CA cases from a literature review (523 cases) and efficacy analysis (245 cases), and created the first evidence-based treatment algorithm for this condition. Treatment success is substantial when using a stepwise combination of CM followed by lymphangiography±embolization.

Purpose: To describe the perioperative safety, functional and immediate post-operative oncological outcomes of minimally invasive RPLND (miRPLND) for testis cancer., Methods: We performed a retrospective multi-centre cohort study on testis cancer patients treated with miRPLND from 16 institutions in eight countries. We measured clinician-reported outcomes stratified by indication. We performed logistic regression to identify predictors for maintained postoperative ejaculatory function., Results: Data for 457 men undergoing miRPLND were studied. miRPLND comprised laparoscopic (n = 56) or robotic (n = 401) miRPLND. Indications included pre-chemotherapy in 305 and post-chemotherapy in 152 men. The median retroperitoneal mass size was 32 mm and operative time 270 min. Intraoperative complications occurred in 20 (4%) and postoperative complications in 26 (6%). In multivariable regression, nerve sparing, and template resection improved ejaculatory function significantly (template vs bilateral resection [odds ratio (OR) 19.4, 95% confidence interval (CI) 6.5-75.6], nerve sparing vs non-nerve sparing [OR 5.9, 95% CI 2.3-16.1]). In 91 men treated with primary RPLND, nerve sparing and template resection, normal postoperative ejaculation was reported in 96%. During a median follow-up of 33 months, relapse was detected in 39 (9%) of which one with port site (< 1%), one with peritoneal recurrence and 10 (2%) with retroperitoneum recurrences., Conclusion: The low proportion of complications or peritoneal recurrences and high proportion of men with normal postoperative ejaculatory function supports further miRPLND studies., (© 2022.

Importance: Level I evidence has failed to demonstrate an overall survival (OS) advantage for cytoreductive nephrectomy in patients with metastatic clear cell renal cell carcinoma (ccRCC) in the modern era, which is at odds with observational studies reporting a marked OS benefit associated with these operations. These observational studies were not designed to adjust for unmeasured confounding., Objective: To assess whether cytoreductive nephrectomy is associated with improved OS in patients with metastatic ccRCC., Design, Setting, and Participants: This cohort study identified patients with metastatic ccRCC in the National Cancer Database from January 1, 2006, to December 31, 2016, who received systemic targeted therapy. The analysis was finalized on July 23, 2021., Exposures: Receipt of cytoreductive nephrectomy., Main Outcomes and Measures: The primary outcome was OS from the date of diagnosis to death or censoring at last follow-up. Distance from the patients' zip code of residence to the treating facility was identified as a valid instrument and was used in a 2-stage residual inclusion instrumental variable analysis. Conventional adjustments for selection bias, multivariable Cox proportional hazards regression, and propensity score matching were performed for comparison. Measured covariates adjusted for in all analyses included age, sex, race, Charlson-Deyo score, facility type, year of diagnosis, clinical T stage, and clinical N stage., Results: The final study population included 12 766 patients (median age, 63 years; IQR, 56-70 years; 8744 [68%] male; 11 206 [88%] White). Cytoreductive nephrectomy was performed in 5005 patients (39%). Conventional adjustments for selection bias demonstrated a significant OS benefit associated with cytoreductive nephrectomy (multivariable Cox proportional hazards regression: hazard ratio [HR], 0.49; 95% CI, 0.47-0.51; propensity score matching: HR, 0.48; 95% CI, 0.46-0.50). Instrumental variable estimates did not demonstrate an association between cytoreductive nephrectomy and OS (HR, 0.92; 95% CI, 0.78-1.09)., Conclusions and Relevance: Instrumental variable analysis did not demonstrate a survival advantage associated with cytoreductive nephrectomy for patients with metastatic ccRCC. This discrepancy likely reflects the fact that surgical indication for cytoreductive nephrectomy is primarily driven by factors that are not commonly measured or available in observational data sets.

Background: To assess predictors, indicators and medical necessity of readmissions after neoadjuvant chemotherapy and radical cystectomy in order to identify opportunities for reducing readmission rates., Methods: Records for patients treated with cisplatin-based neoadjuvant chemotherapy followed by radical cystectomy between 2007 and 2017 were reviewed for 90-day complications and readmission. Readmissions were classified as necessary vs. discretionary based on independent clinician review. The association between postoperative complications and necessary or discretionary readmission were examined with adjusted regression models., Results: Among a total of 250 patients, 76 patients (30.4%) were readmitted within 90 days of surgery (19 discretionary and 57 necessary). Age, insurance coverage, and comorbidity were similar between readmitted and non-readmitted patients. Readmission was more likely after neobladder than ileal conduit (39% vs. 23%, P = 0.02). Major (grade ≥ 3) complications within 90-day of surgery including index admission and post-discharge period were significantly more common among re-admitted patients compared to patients who were not readmitted (40% in necessary, 21% in discretionary, 3% in none, P < 0.001). Median length of stay on readmission was twice as long in necessary cases compared to discretionary cases (5 vs. 2.5 days, P < 0.001). Gastrointestinal and infectious complications were associated with discretionary readmission in adjusted analyses, while infectious, renal/genitourinary and thromboembolic complications were associated with necessary readmission., Conclusions: Twenty-five percent of readmissions were categorized as discretionary and were driven primarily by low-grade gastrointestinal complications, marginal oral intake and failure to thrive, suggesting that better coordinated post-discharge supportive care could help avoid a substantial proportion of readmissions., Competing Interests: Conflict of Interest Statement The authors declare no conflict of interest., (Copyright © 2021 Elsevier Inc.

Background: Preoperative malnourishment has been consistently associated with poor outcomes after radical cystectomy and other major abdominal surgeries. Most enhanced recovery after surgery (ERAS) studies have examined preoperative nutrition and its relationship to outcomes after gastrointestinal surgery. Although numerous studies have demonstrated the benefits of using an ERAS protocol, this study in unique in comparing 2 ERAS protocols, with and without a nutrition component., Methods: A formalized preoperative nutrition protocol (PNP) recommending use of preoperative immunonutrition and carbohydrate drink was introduced in June 2018. A total of 78 consecutive patients who drank both beverages were compared with 92 historical controls. Multivariable logistic regression analyses were sequentially performed to determine if preoperative nutrition was associated with binary outcome variables (30-day complication, infectious complication, and readmission within 30 days)., Results: The preoperative nutrition group and control group were statistically similar in distribution of age, sex, American Society of Anesthesiologists physical status classification, clinical stage, and body mass index. Return of bowel function was found to occur earlier in the preoperative nutrition group than in the control group (3.12 vs 3.74 days; relative risk, 0.82; CI, 0.73-0.93; P = .0029). Complications within 30 days were similar in both groups (63.6% vs 55.4%; P = 0.36). Infectious complications (42.9% vs 37%; P = .53) and readmission within 30 days (22.1% vs 15.2%; P = .34) were also similar in both groups., Conclusions: Use of a PNP including immunonutrition and carbohydrate drink may be associated with earlier return of bowel function after radical cystectomy., (© 2021 American Society for Parenteral and Enteral Nutrition.)

Purpose: Following radical orchiectomy, surveillance and primary retroperitoneal lymph node dissection (RPLND) are acceptable options for the management of early stage pure testicular teratoma in adult patients; however, there is no uniform consensus. The aim of this study was to investigate survival outcomes of adults with early stage pure testicular teratoma based on management strategy., Methods: Data was extracted from the National Cancer Database (NCDB) from testicular cancer patients diagnosed with clinical stage (CS) I pure teratoma (pT1-4N0M0S0) between 2004 and 2014. Kaplan-Meier and Cox regression analyses were used to assess clinical outcomes based on management strategy., Results: Of the 61,167 patients diagnosed with testicular cancer, 692 (1.1%) had pure teratoma. Only individuals with CS I disease were considered (n = 237). The median age was 28 (23-35) years. Overall, 43 (18%) patients underwent RPLND and 194 (82%) patients were managed with surveillance. There was an increase in surveillance for CS I teratoma during the study period. Increasing distance from residence to treatment facility was an unadjusted predictor for undergoing primary RPLND (p < 0.001). Median follow-up was 54 months and there was no significant difference in overall survival between CS I teratoma patients managed with RPLND and those managed with surveillance (p = 0.13)., Conclusions: There has been a trend toward increasing adoption of surveillance for the management of early stage pure testicular teratoma in adults. Our findings suggest that surveillance provides comparable survival outcomes to primary retroperitoneal lymph node dissection in this setting.

Coronavirus Disease 2019 has impacted all aspects of urologic training. Didactics have shifted to a virtual platform and new approaches to surgical training have been undertaken. There has been a shift in research away from the laboratory space, with an increased focus on clinical outcomes and multi-institutional collaborations. Finally, there have been impacts on home life, questions about time away from work, case logs and case minimums, as well as how to manage resident and fellow reassignment. Herein, we review the current state of urologic education in the United States, focusing specifically on urologic oncology and highlight opportunities for the future., (Copyright © 2020 Elsevier Inc.

Anemia occurs in a significant group of patients with bladder cancer before radical cystectomy. Iron deficiency is a readily identifiable cause of anemia, which can be treated before surgery. The proportion of patients with bladder cancer with iron deficiency anemia is unknown. Laboratory and clinical outcomes were collected on 47 consecutive patients presenting for radical cystectomy. Iron studies found 30% of patients had iron deficiency anemia. These findings present an opportunity to treat anemia before surgery, to reduce blood transfusions during radical cystectomy., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2021 International Anesthesia Research Society.)

A clearer understanding of the tumor immune microenvironment (TIME) in metastatic clear cell renal cell carcinoma (ccRCC) may help to inform precision treatment strategies. We sought to identify clinically meaningful TIME signatures in ccRCC. We studied tumors from 39 patients with metastatic ccRCC using quantitative multiplexed immunofluorescence and relevant immune marker panels. Cell densities were analyzed in three regions of interest (ROIs): tumor core, tumor-stroma interface and stroma. Patients were stratified into low- and high-marker density groups using median values as thresholds. Log-rank and Cox regression analyses while controlling for clinical variables were used to compare survival outcomes to patterns of immune cell distributions. There were significant associations with increased macrophage (CD68 + CD163 + CD206 + ) density and poor outcomes across multiple ROIs in primary and metastatic tumors. In primary tumors, T-bet + T helper type 1 (Th1) cell density was highest at the tumor-stromal interface (P = 0·0021), and increased co-expression of CD3 and T-bet was associated with improved overall survival (P = 0·015) and survival after immunotherapy (P = 0·014). In metastatic tumor samples, decreased forkhead box protein 3 (FoxP3) + T regulatory cell density correlated with improved survival after immunotherapy (P = 0·016). Increased macrophage markers and decreased Th1 T cell markers within the TIME correlated with poor overall survival and treatment outcomes. Immune markers such as FoxP3 showed consistent levels across the TIME, whereas others, such as T-bet, demonstrated significant variance across the distinct ROIs. These findings suggest that TIME profiling outside the tumor core may identify clinically relevant associations for patients with metastatic ccRCC., (© 2021 British Society for Immunology.)

Purpose of Review: A number of promising therapies for Bacillus Calmette-Guerin (BCG) unresponsive nonmuscle invasive bladder cancer (NMIBC) are in the pipeline. In this review, we discuss the history of immunotherapy for the treatment of NMIBC and future developments, focusing on novel intravesical treatments., Recent Findings: The term BCG unresponsive NMIBC encompasses patients with both BCG refractory and BCG relapsing disease. This definition was adopted to standardize inclusion criteria for patients enrolling in clinical trials in this setting. A host of intravesical immuno-oncologic therapies that include gene therapies, oncolytic viruses, cell surface molecule delivered immunotoxins, and cytokine driven agonism of cellular immunity, are in various phases of the drug development pipeline. In addition, pembrolizumab, an immune-checkpoint inhibitor, has recently been approved as a treatment option for BCG unresponsive NMIBC., Summary: Patients with BCG unresponsive disease face many difficulties. Although radical cystectomy is the most effective treatment option for these patients, it is associated with significant morbidity, difficult recovery challenges, and refusal by many patients. Cancer immunotherapies may provide bladder sparing options for some patients who develop BCG unresponsive disease., (Copyright © 2020 Wolters Kluwer Health, Inc. All rights reserved.)

Background: In patients with haematuria, a fast, noninvasive test with high sensitivity (SN) and negative predictive value (NPV), which is able to detect or exclude bladder cancer (BC), is needed. A newly developed urine assay, Xpert Bladder Cancer Detection (Xpert), measures five mRNA targets (ABL1, CRH, IGF2, UPK1B, and ANXA10) that are frequently overexpressed in BC., Objective: To validate the performance of Xpert in patients with haematuria., Design, Setting, and Participants: Voided precystoscopy urine specimens were prospectively collected at 22 sites from patients without prior BC undergoing cystoscopy for haematuria. Xpert, cytology, and UroVysion procedures were performed. Technical validation was performed and specificity (SP) was determined in patients without BC., Outcome Measurements and Statistical Analysis: Test characteristics were calculated based on cystoscopy and histology results, and compared between Xpert, cytology, and UroVysion., Results and Limitations: We included 828 patients (mean age 64.5 yr, 467 males, 401 never smoked). Xpert had an SN of 78% (95% confidence interval [CI]: 66-87) overall and 90% (95% CI: 76-96) for high-grade (HG) tumours. The NPV was 98% (95% CI: 97-99) overall. The SP was 84% (95% CI: 81-86). In patients with microhaematuria, only one HG patient was missed (NPV 99%). Xpert had higher SN and NPV than cytology and UroVysion. Cytology had the highest SP (97%). In a separate SP study, Xpert had an SP of 89% in patients with benign prostate hypertrophy and 92% in prostate cancer patients., Conclusions: Xpert is an easy-to-use, noninvasive test with improved SN and NPV compared with cytology and UroVysion, representing a promising tool for identifying haematuric patients with a low likelihood of BC who might not need to undergo cystoscopy., Patient Summary: Xpert is an easy-to-perform urine test with good performance compared with standard urine tests. It should help identify (micro)haematuria patients with a very low likelihood to have bladder cancer., (Copyright © 2020 The Author(s). Published by Elsevier B.V. All rights reserved.)

Purpose: Although neoadjuvant chemotherapy is associated with a survival advantage in pure urothelial, muscle invasive bladder cancer, the role of neoadjuvant chemotherapy is less clear in variant histology or urothelial carcinoma with divergent differentiation. We compared chemotherapy response and survival outcomes of patients with nonpure urothelial carcinoma histology who were managed with neoadjuvant chemotherapy followed by cystectomy vs cystectomy alone., Materials and Methods: We analyzed 768 patients with clinical muscle invasive bladder cancer (cT2-4N0M0) who were treated with cystectomy at a tertiary care center from 2007 to 2017. Patients were stratified by histology and treatment strategy. Adjusted logistic and Cox regression models were used to evaluate pathological downstaging, cancer specific survival and overall survival., Results: The cohort consisted of 410 patients (53%) with pure urothelial carcinoma, 185 (24%) with urothelial carcinoma with divergent differentiation and 173 (23%) with variant histology. Overall, 314 patients (41%) received neoadjuvant chemotherapy prior to cystectomy. There were similar rates of complete (18% to 30%) and partial (37% to 46%) pathological downstaging with neoadjuvant chemotherapy across all histological subgroups (p=0.30 and p=0.40, respectively). However, while patients with pure urothelial carcinoma experienced an overall survival benefit (HR 0.71, 95% CI 0.51-0.98, p=0.0013) and those with variant histology experienced a cancer specific survival benefit (HR 0.55, 95% CI 0.30-0.99, p=0.0495) with neoadjuvant chemotherapy, patients with urothelial carcinoma with divergent differentiation did not experience overall or cancer specific survival benefits with the use of neoadjuvant chemotherapy prior to cystectomy., Conclusions: Among patients with muscle invasive bladder cancer those with nonpure urothelial carcinoma histology with variant histology achieved nearly equivalent response rates and survival benefits with the use of neoadjuvant chemotherapy as those with pure urothelial carcinoma, while patients with urothelial carcinoma with divergent differentiation experienced significantly worse survival outcomes regardless of the use of neoadjuvant chemotherapy prior to cystectomy.

Approximately 10%-20% of patients with clinically localized clear cell renal cell carcinoma (ccRCC) at time of surgery will subsequently experience metastatic progression. Although considerable progression was seen in the systemic treatment of metastatic ccRCC in last 20 years, once ccRCC spreads beyond the confines of the kidney, 5-year survival is less than 10%. Therefore, significant clinical advances are urgently needed to improve overall survival and patient care to manage the growing number of patients with localized ccRCC. We comprehensively evaluated expression of 388 candidate genes related with survival of ccRCC by using TCGA RNAseq (n = 515), Total Cancer Care (TCC) expression array data (n = 298), and a well characterized Moffitt RCC cohort (n = 248). We initially evaluated all 388 genes for association with overall survival using TCGA and TCC data. Eighty-one genes were selected for further analysis and tested on Moffitt RCC cohort using NanoString expression analysis. Expression of nine genes (AURKA, AURKB, BIRC5, CCNE1, MK167, MMP9, PLOD2, SAA1, and TOP2A) was validated as being associated with poor survival. Survival prognostic models showed that expression of the nine genes and clinical factors predicted the survival in ccRCC patients with AUC value: 0.776, 0.821 and 0.873 for TCGA, TCC and Moffitt data set, respectively. Some of these genes have not been previously implicated in ccRCC survival and thus potentially offer insight into novel therapeutic targets. Future studies are warranted to validate these identified genes, determine their biological mechanisms and evaluate their therapeutic potential in preclinical studies., (© 2020 The Authors.

Objectives: To evaluate the safety and feasibility of focal bipolar radiofrequency ablation in men with localized prostate cancer., Methods: A review of 10 patients treated with a novel bipolar radiofrequency ablation probe integrated in a coil design (Encage; Trod Medical, Bradenton, FL, USA) between 2011 and 2017 in two prospective pilot trials. All men had clinical stage T1c prostate cancer, prostate-specific antigen <10 ng/mL and Gleason score ≤7. Ablation was carried out under general anesthesia, and bipolar probes were inserted transperineally under transrectal ultrasound guidance. Treatment-related adverse events, quality of life and negative biopsy rate were evaluated at 6 months after ablation. The Wilcoxon signed-rank test was used to compare baseline and post-treatment symptom scores., Results: The median age was 58 years (range 50-64 years) and the median prostate volume was 49.65 cc (range 21-68 cc). Prostate cancer with a Gleason score of 6 (3 + 3) and 7 (3 + 4) was noted in seven and three patients, respectively. The median number of radiofrequency ablation cycles was 2.5 (range 2-5). All patients were catheter-free and able to void the day of surgery. Within 6 months after ablation, all adverse events were low grade, with the exception of one grade 3 hematuria that required cystoscopy without coagulation. Six months after ablation bowel, urinary and hormonal functions, and overall satisfaction remained stable. Erectile dysfunction occurred in two out of four patients who had normal sexual function before the procedure. Neither urinary incontinence nor urinary infection was noted., Conclusions: This first report on focal bipolar radiofrequency ablation documents a safe and feasible treatment option for selected patients with localized prostate cancer., (© 2020 The Japanese Urological Association.)
