Urothelial carcinoma is an aggressive entity that is associated with significant morbidity, but there have been major advances in both our understanding of and treatment options for patients with this disease. In this review, the authors focus on novel therapeutic and diagnostic approaches in the perioperative setting, with an emphasis on patient‐centered and individualized care. For urothelial carcinoma of the bladder (UCB), advances in nonplatinum‐based therapies, specifically immunotherapy and antibody–drug conjugates, have expanded the therapeutic arsenal for patients with muscle‐invasive UCB in both the neoadjuvant and adjuvant settings to improve survival outcomes. Given the significant morbidity of extirpative surgery (radical cystectomy and urinary diversion), there have also been greater efforts to evaluate bladder‐sparing protocols and improve the selection of patients for surgery and their postoperative recovery. The authors review special considerations for organ‐sparing surgery in females, geriatric co‐management, and enhanced recovery after surgery protocols. For upper tract urothelial carcinoma, there has been increasing recognition of its unique diagnostic and therapeutic challenges, including risks of renal functional loss. There have been advances in molecular profiling that have demonstrated various genomic differences between upper tract urothelial carcinoma and UCB, with treatment implications. This article reviews studies evaluating perioperative care that focused on optimizing therapeutic approaches, including neoadjuvant/adjuvant chemotherapy and immunotherapy, as well as nephron‐sparing strategies in carefully selected cases.

Background/Objectives: Upper tract urothelial carcinoma (UTUC) is a rare and biologically distinct subset of urothelial malignancies, comprising approximately 5–10% of urothelial cancers. UTUC presents unique diagnostic and therapeutic challenges, with both a higher likelihood of invasive disease at presentation and a less favorable prognosis compared to urothelial carcinoma of the bladder. Current treatment strategies for UTUC are largely derived from bladder cancer studies, underscoring the need for UTUC-directed research. This review provides a comprehensive overview of UTUC, encompassing diagnostic approaches, systemic and intraluminal therapies, surgical management, and future directions. Methods: A narrative review was conducted synthesizing evidence from guideline-based recommendations, retrospective and prospective clinical studies, and ongoing trials focused on UTUC. Results: Neoadjuvant cisplatin-based chemotherapy is increasingly preferred in UTUC due to the risk of postoperative renal impairment that may preclude adjuvant cisplatin use. Surgical management includes kidney-sparing approaches and radical nephroureterectomy (RNU), with selection guided by tumor risk and patient comorbidities. While endoscopic management (EM) preserves renal function, it carries a higher recurrence and surveillance burden; RNU remains standard for high-risk cases. Systemic therapy for advanced and metastatic UTUC mirrors that of bladder urothelial carcinoma. Enfortumab vedotin (EV) plus pembrolizumab showed superior efficacy over chemotherapy in the EV-302 trial, with improved response rate, progression-free survival, and overall survival across subgroups, including UTUC. For patients ineligible for EV, the CheckMate-901 study supported first-line chemoimmunotherapy with gemcitabine, cisplatin, and nivolumab. Further systemic therapy strategies include maintenance avelumab post-chemotherapy (JAVELIN Bladder 100), targeted therapies such as erdafitinib (THOR trial), and trastuzumab deruxtecan (DESTINY-PanTumor02) in FGFR2/3-altered and HER2-positive disease, respectively. Conclusions: Historically, the therapeutic landscape of UTUC has been extrapolated from bladder cancer; however, ongoing research specific to UTUC is deriving more precise regimens involving the use of immune checkpoint inhibitors, antibody–drug conjugates, and biomarker-driven therapies.

Introduction: Bladder cancer is a common malignancy in the United States and while the majority are non-muscle invasive at diagnosis, those with muscle-invasive and locally advanced disease can be challenging to manage. In addition, the prognosis is poorer in this group with high rates of recurrence following treatment. Clinical trials and advances in systemic therapy have helped to improve outcomes for these patients. Materials/methods: Articles were chosen for inclusion based on expert knowledge of the literature and PubMed literature searches for the relevant areas, with a focus on clinical trials. Appropriate articles were selected for inclusion by reviewing article titles, abstracts and full texts. Results: The standard of care for treatment of muscle invasive bladder cancer involves neoadjuvant chemotherapy followed by radical cystectomy. The NIAGARA trial recently changed the standard of care to include immunotherapy both in the neoadjuvant and adjuvant settings. Multiple clinical trials have assessed the potential benefit of adjuvant immunotherapy in patients with high-risk disease after radical cystectomy, leading to the approval of nivolumab in this setting. Improvements in staging and surveillance of these patients are necessary. The use of circulating tumor DNA and advances in imaging have also shown promise in prognostication and detection and monitoring of recurrence. Conclusions: Locally advanced bladder cancer is a challenging condition to manage, and while advances have been made in systemic therapy and biomarkers such as circulating tumor DNA, further investigation is needed to continue to improve outcomes for this group of patients.

Background: Testicular cancer is the most common malignancy diagnosed in adolescents and young adults, and evidence has emerged regarding disparities that affect different groups of patients. Methods: In this article, we conducted a thorough review of this area and summarized the existing literature. Results: Some of the pertinent findings from our review include poorer outcomes for various groups including the native Māori population of New Zealand, those who live in the United States–Mexico border region, those who live in Eastern Europe, those who are uninsured and those with poorer socioeconomic status, amongst others. In the United States specifically, there is significant evidence showing that racial/ethnic minorities, compared to white patients, tend to fare worse with later presentation at higher stages and worse survival rates. Hispanic patients in particular appear to have the potential for more aggressive tumor biology than other groups and are projected to have the highest incidence rates in the US by 2026. Conclusions: Overall, disparities exist in many aspects of testicular cancer and are striking in some instances, and further research is needed in this arena and in potential solutions.

In recent decades, serum tumor markers (STMs) have emerged as valuable adjuncts in early cancer detection and post-treatment surveillance. STMs are inexpensive, minimally invasive, and readily accessible tools that can be used to diagnose cancers, monitor patients’ responses to treatment, and even detect recurrence without imposing additional burdens on patients. Emerging evidence has demonstrated the reliability of STMs in the prognostication of bladder cancer (BC). However, their potential role extends beyond prognostication. This review intends to provide a multidimensional picture of STM applications in muscle-invasive bladder cancer (MIBC). In addition, we supplement this review with real-life clinical experiences from our institution to further illustrate the clinical feasibility of STMs in MIBC.
