Management of Bulky Inguinal and Pelvic Lymph Nodes.

Penile cancer with bulky inguinal metastasis has a high probability of harboring pathologically involved lymph nodes best managed in a multidisciplinary care setting. Appropriate staging with cross-sectional imaging and fine-needle aspirate cytology of suspicious nodes guide decision-making for the use of platinum-based neoadjuvant chemotherapy followed by inguinal lymph node dissection. Surgical resection plays an important diagnostic, therapeutic, and guiding role in disease management. Patients with adverse pathologic features, especially those with extranodal disease extension, may derive additional benefit from adjuvant radiotherapy.

Overview of Systemic Therapies in Penile Cancer.

Penile cancer (PC), although rare, poses significant challenges in both diagnosis and treatment. Penile squamous cell carcinoma (PSCC) represents the most common histologic subtype of PC, accounting for approximately 95% of cases. With limited therapeutic options available, systemic therapies have emerged as critical components in the management of advanced PSCC. Recent developments in clinical research have revealed the effectiveness of new therapeutic strategies. By elucidating the mechanism of action and clinical evidence supporting these treatments, we strive to offer insights into optimizing treatment strategies and enhancing the quality of care for patients affected by this complex disease.

Systematic Review of the Global Literature on Uncomplicated Recurrent Urinary Tract Infections in Women: Underscoring Major Heterogeneity.

OBJECTIVE: To examine the global literature database on uncomplicated recurrent urinary tract infections (rUTI), this systematic review assesses the availability of rUTI data based on geographic region and elucidates the current state of research and gaps in knowledge. METHODS: The databases PubMed, Embase, WHO Global Index Medicus, and SciELO were searched for keywords related to rUTI between 2000 and 2023. Three independent reviewers screened studies restricted to female participants age ≥18 years with uncomplicated rUTIs. Studies were excluded if they did not provide a definition for rUTI or did not cite or report an estimate for rUTI prevalence. The review was registered in PROSPERO and conformed to PRISMA guidelines. RESULTS: The search yielded 2947 studies of which 124 were ultimately included. Convenience samples were used for 91% of studies and sample sizes were 30% n <50, 29% n = 50-99, 22% n = 100-199, 36% n ≥200. Most studies were conducted in Europe (41%) or North America (39%), were prospective (52%), at tertiary centers (49%) and included all ages ≥18 (60%). The most common definition for rUTI was 2 UTI/6 m or 3 UTI/1y (62%). Regardless of study location, most studies cited prevalence estimates for rUTI derived from U.S.-based populations. CONCLUSION: This study represents the first formal investigation of the global literature base on uncomplicated rUTI. Studies on rUTIs are globally of small scale and definitions used for rUTI are heterogeneous. More studies are needed to ascertain the true prevalence of rUTI outside of North America and Europe.

Systematic Review of the Global Use of Validated Questionnaires in the Management of Stress Urinary Incontinence in Women.

INTRODUCTION: Our goal was to systematically review the most commonly used validated questionnaires in recent global literature on stress urinary incontinence (SUI) treatment. METHODS: PubMed, Embase, and Ovid databases were queried for manuscripts containing "female stress urinary incontinence" AND "diagnosis" AND "treatment" AND "questionnaire." Two independent reviewers screened studies for randomized controlled trials, prospective, and retrospective studies between 2018 and 2023. Exclusion criteria included male participants, non-SUI incontinence, and articles not originally written in English. The review was registered in PROSPERO [465721] and conformed to PRISMA guidelines. RESULTS: In 117 manuscripts meeting study criteria, the median of the mean ages was 52 years, with a median of 164 participants per study. Most studies originated in Europe (59/117). The International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form was the most frequently used (52%), followed by the Patient Global Impression of Improvement (31%), the Urinary Distress Inventory 6 Short Form (25%), the Incontinence Quality of Life (20%), and the Incontinence Impact Questionnaire Short Form (19%). These leading questionnaires were short, translated into several languages, and globally addressed important SUI-related domains, including the presence and severity of SUI, additional lower urinary tract symptoms, and the impact of SUI on quality of life, as well as changes perceived after treatment. CONCLUSIONS: This systematic review of the validated questionnaires used in contemporary SUI management literature could help guide recommendations for incorporating these favored instruments into future SUI treatment outcome documents.

The spectrum of cutaneous toxicities related to novel genitourinary cancer therapies.

CONTEXT: Genitourinary cancers (GUCs) encompass malignancies affecting the urinary and reproductive systems, including renal cell carcinoma (RCC), urothelial carcinoma (UC), and prostate cancer (PC). With the rapidly evolving therapeutic domain of these cancers, cutaneous adverse events (AEs) remain among the most observed toxicities. OBJECTIVE: To explore the dermatologic AEs linked to novel GUC treatments, their underlying pathophysiology, clinical presentations, and risk factors. EVIDENCE ACQUISITION: A narrative review of the literature from PubMed and Embase databases was conducted. The search strategy included dermatologic/cutaneous adverse events, risk factors, and pathophysiology in conjunction with the following classes of therapies; immune checkpoint inhibitors (ICIs), antiangiogenic therapies, enfortumab vedotin (EV), erdafitinib, and androgen receptor antagonists (ARAs). EVIDENCE SYNTHESIS: Maculopapular rash, pruritus, and alopecia are present among the five classes of therapies. ICIs demonstrate the highest incidence of severe drug AEs including Steven Johnson syndrome/toxic epidermal necrolysis. Unique cutaneous AEs present with specific therapies including hand-foot skin reaction and subungual splinter hemorrhage with antiangiogenic drugs, stomatitis/mucositis and onycholysis with erdafitinib. Incidence and type of cutaneous AE also differed within therapies in the same class as seen with apalutamide displaying the highest risk of cutaneous AEs within ARAs. Risk factors for development of cutaneous AEs can be general to therapies, or specific, and include age, immune status, BMI, and gender. CONCLUSIONS: Dermatologic AEs may impact patients' quality of life and increase the tendency to dose reduce, hold or discontinue life-saving therapies, underscoring the need for vigilant monitoring, early recognition, and collaborative management between medical oncologists, pharmacists, dermatologists and other specialists.

Current Status and Challenges in Rare Genitourinary Cancer Research and Future Directions.

PURPOSE OF REVIEW: In contemporary urological practice, managing rare genitourinary (GU) malignancies presents significant challenges, necessitating a comprehensive understanding of their unique characteristics and tailored treatment approaches. RECENT FINDINGS: Rare GU malignancies, whether per se, variants of common histologies, or common tumors in uncommon locations, often lack widely available clinical guidelines. Consequently, treatment decisions are frequently based on empirical evidence, risking suboptimal outcomes. However, recent advances in molecular profiling, targeted therapies, and immunotherapy offer promising avenues for improving management strategies and patient outcomes. This review provides a comprehensive overview of some rare GU malignancies encountered in clinical practice, including their distinct pathological features, current management approaches, and ongoing research directions. Understanding the complexities of these rare tumors and implementing multidisciplinary treatment strategies are essential for optimizing patient care and improving survival outcomes.

Factors predictive of recurrence, metastasis and death in node-negative penile squamous cell carcinoma: A retrospective multicentre cohort study.

BACKGROUND: Penile squamous cell carcinoma (PSCC) carries significant morbidity and mortality. Literature is limited regarding prognostic factors, especially prognostic factors for development of metastasis. OBJECTIVES: To identify independent prognostic factors associated with poor outcomes, defined as local recurrence (LR), metastasis and disease-specific death (DSD) in clinically node-negative PSCC undergoing local therapy. METHODS: Thirty-two-year Retrospective Multicenter Cohort Study of 265 patients with histologically diagnosed PSCC at three tertiary care centres. Predictive models based on patient or tumour characteristics were developed. RESULTS: Local recurrence occurred in 56 patients, metastasis in 52 patients and DSD in 40 patients. In multivariable models, the following five factors were independent prognostic factors based on subhazard ratio (SHR): history of balanitis (LR SHR: 2.3; 95% CI 1.2-4.2), poor differentiation (metastasis SHR 1.9; 95% CI 1.0-3.6), invasion into the corpora (metastasis SHR: 3.0; 95% CI 1.5-5.8 and DSD SHR: 4.5; 95% CI 1.7-12.1), perineural invasion (PNI) (metastasis SHR: 2.8; 95% CI 1.4-5.5 and DSD SHR: 3.5; 95% CI, 1.6-7.8) and a history of phimosis (DSD SHR: 2.5; 95% CI 1.2-5.3). The 5-year cumulative incidence of metastasis was higher for tumours with PNI [cumulative incidence function (CIF) = 55%, 95% CI 38-75 vs. CIF 15%, 95% CI 11-22], corporal invasion (CIF: 35%, 95% CI 26-47 vs. 12%, 95% CI 7-19) and poorly differentiated tumours (CIF = 46%, 95% CI 31-64 vs. CIF 15%, 95% CI 11-22). CONCLUSIONS: History of balanitis, history of phimosis, PNI, corporal invasion and poor differentiation are independent risk factors associated with poor outcomes. Since poor differentiation and PNI currently constitute only T1b disease, prognostic staging can likely be improved.

From Detection to Cure - Emerging Roles for Urinary Tumor DNA (utDNA) in Bladder Cancer.

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.

Optimizing the Use of Next-Generation Sequencing Assays in Patients With Urothelial Carcinoma: Recommendations by the 2023 San Raffaele Retreat Panel.

BACKGROUND: The application of precision medicine in clinical practice implies a thorough evaluation of actionable genomic alterations to streamline therapeutic decision making. Comprehensive genomic profiling of tumor via next-generation sequencing (NGS) represents a great opportunity but also several challenges. During the 2023 San Raffaele Retreat, we aimed to provide expert recommendations for the optimal use of NGS in urothelial carcinoma (UC). MATERIALS AND METHODS: A modified Delphi method was utilized, involving a panel of 12 experts in UC from European and United States centers, including oncologists, urologists, pathologists, and translational scientists. An initial survey, conducted before the meeting, delivered 15 statements to the panel. A consensus was defined when ≥70% agreement was reached for each statement. Statements not meeting the consensus threshold were discussed during the meeting. RESULTS: Nine of the 15 statements covering patient selection, cancer characteristics, and type of NGS assay, achieved a consensus during the survey. The remaining six statements addressing the optimal timing of NGS use, the ideal source of tumor biospecimen for NGS testing, and the subsequent need to evaluate the germline nature of certain genomic findings were discussed during the meeting, leading to unanimous agreement at the end of the conference. CONCLUSION: This consensus-building effort addressed multiple unanswered questions regarding the use of NGS in UC. The opinion of experts was in favor of broader use of NGS. In a setting where recommendations/guidelines may be limited, these insights may aid clinicians to provide informed counselling and raise the bar of precision and personalized therapy.

Competitive fitness of asymptomatic bacteriuria E. coli strain 83972 against uropathogens in human urine.

Urinary tract infection (UTI) is one of the most common bacterial infections worldwide. The main causative agent of UTI is uropathogenic Escherichia coli (UPEC). There is an immediate need for novel prophylactic and treatment strategies against UTI because of the increasing incidence of antimicrobial resistance among uropathogens. ABU 83972, an asymptomatic bacteriuria-causing E. coli strain, prevents UTI by suppressing the colonization of UPEC. However, the nature of competition and growth repression of UPEC by ABU 83972 is unclear and is the subject of our investigation. Here, we characterized the growth kinetics of ABU 83972 and uropathogens in human urine and laboratory media. Next, we performed a series of competitive co-culture experiments where ABU 83972 and uropathogens were inoculated at a 1:1 ratio in human urine and in various media, and their relative abundance was determined. In human urine, ABU 83972 outcompeted UPEC and additional uropathogens, reaching up to 90% of the total population after 24 hours of incubation. In contrast, UPEC outcompeted ABU 83972 in LB and M9 minimal media and exhibited superior colonization than ABU 83972 in the mouse urinary bladder. Since engineered living materials (ELMs) can be used to retain an organism of interest in a particular location, we developed ABU 83972-containing ELMs that effectively outcompeted UPEC in human urine. In summary, our work establishes that ABU 83972 outcompetes UPEC in a milieu- and cell-density-dependent manner, highlighting the importance of the metabolites and nutrients found in the human urine as determinants of the competitive fitness of ABU 83972.

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.

Frequency and Nature of Genomic Alterations in ERBB2-Altered Urothelial Bladder Cancer.

BACKGROUND: Human epidermal growth factor-2 (HER2) overexpression is an oncogenic driver in many solid tumors, including urothelial bladder cancer (UBC). In addition, activating mutations in the ERBB2 gene have been shown to play an oncogenic role similar to ERBB2 amplification. OBJECTIVE: To describe and compare the frequency and nature of genomic alterations (GA) of ERBB2-altered (mutations, amplification) and ERBB2 wild-type UBC. PATIENTS AND METHODS: Using a hybrid capture-based comprehensive profiling assay, 9518 UBC cases were grouped by ERBB2 alteration and evaluated for all classes of genomic alterations (GA), tumor mutational burden (TMB), microsatellite instability (MSI), genome-wide loss of heterozygosity (gLOH), and genomic mutational signature. PD-L1 expression was measured by immunohistochemistry (Dako 22C3). Categorical statistical comparisons were performed using Fisher's exact tests. RESULTS: A total of 602 (6.3%) UBC cases featured ERBB2 extracellular domain short variant (SV) GA (ECDmut+), 253 (2.7%) cases featured ERBB2 kinase domain SV GA (KDmut+), 866 (9.1%) cases had ERBB2 amplification (amp+), and 7797 (81.9%) cases were ERBB2 wild-type (wt). European genetic ancestry of ECDmut+ was higher than ERBB2wt. Numerous significant associations were observed when comparing GA by group. Notably among these, CDKN2A/MTAP loss were more frequent in ERBB2wt versus ECDmut+ and amp+. ERBB3 GA were more frequent in ECDmut+ and KDmut+ than ERBB2wt. TERT GA were more frequent in ECDmut+, KDmut+, and amp+ versus ERBB2wt. TOP2A amplification was significantly more common in ECDmut+ and amp+ versus ERBB2wt, and TP53 SV GA were significantly higher in ERBB2 amp+ versus ERBB2wt. Mean TMB levels were significantly higher in ECDmut+, KDmut+, and amp+ than in ERBB2wt. Apolipoprotein B mRNA-editing enzyme, catalytic polypeptides (APOBEC) signature was more frequent in ECDmut+, KDmut+, and amp+ versus ERBB2wt. No significant differences were observed in PD-L1 status between groups, while gLOH-high status was more common in amp+ versus ERBB2wt. MSI-high status was more frequent in KDmut+ versus ERBB2wt, and in ERBB2wt than in amp+. CONCLUSIONS: We noted important differences in co-occurring GA in ERBB2-altered (ECDmut+, KDmut+, amp+) versus ERBB2wt UBC, as well as higher mean TMB and higher APOBEC mutational signature in the ERBB2-altered groups. Our results can help refine future clinical trial designs and elucidate possible response and resistance mechanisms for ERBB2-altered UBC.

Urethral cancer: a comprehensive review endorsed by the Global Society of Rare Genitourinary Tumours.

OBJECTIVE: To determine the effectiveness and adverse effects of urethrectomy alone or as part of multimodal therapy (MMT). METHODS: A comprehensive search was conducted across MEDLINE (OVID), EMBASE, LILACS and the Cochrane Central Register of Controlled Trials (CENTRAL) databases, from their inception to the present date. The study cohort comprised individuals aged 16 years and older diagnosed with urethral tumours at any stage who underwent either isolated urethrectomy or urethrectomy as an integral component of MMT. RESULTS: Ninety-two studies comprising 25 480 patients met the inclusion criteria. Surgical outcomes for urethral cancer vary considerably, with 5-year overall survival (OS) ranging from 10% to 68% based on disease extent, approach, and gender. Radiotherapy (RT) alone provides 5-year OS of approximately 40%. Combined regimens provide better outcomes compared to single modalities, including reduced recurrence and enhanced survival. However, trimodal therapy showed survival benefits only for urothelial subtypes, indicating the need to tailor management according to cancer type. MMT with neoadjuvant chemotherapy prior to surgery demonstrated the most consistent survival gains. CONCLUSIONS: The management of urethral cancer demands a nuanced, personalised approach, accounting for factors such as tumour location, sex, and tumour stage. MMT combining surgery, chemotherapy and RT has shown the ability to enhance outcomes in advanced disease. More extensive collaborative studies through specialised centres are imperative to advance evidence-based protocols and refine treatment in order to improve survival.
