Special Issue Information

Dear Colleagues,

This collection is the second edition of a previous Special Issue on “New Advances in Urothelial Cancer: Diagnosis, Therapy and Prognosis” (https://www.mdpi.com/journal/cancers/special_issues/UCs).

Urothelial cancers are the sixth most common tumors in developed countries. Bladder tumors account for 90–95% of UCs and are the most common urinary tract malignancy; by contrast, upper urinary tract UCs are uncommon and account for only 5–10% of UCs. In recent years, new urothelial biomarkers have been proposed in their diagnostic and prognostic role; liquid biopsy has arisen as an important tool for urothelial cancer early detection and prognosis, identifying different pathways of cell signaling, proliferation, and apoptosis changes in tumor biology and progression. New immunotherapy agents based on checkpoint inhibitor-optimized cancer therapy and oncologic outcomes have emerged, and device-assisted therapy (EMDA, thermochemotherapy) has been outlined as a preserving approach to recurrent non-muscle invasive bladder disease, while the minimally invasive approach of robotic surgery has been found to reduce adverse events and hospital stay when major urologic surgery is needed. The purpose of this Special Issue is to identify and summarize the latest innovations in urothelial cancer management, overcome present challenges and open new paths to future strategies.

Background/Objectives: Given the increasing interest in the predictive role of inflammation in oncology, we aimed to assess the association between inflammatory factors (IFs) and the histopathological characteristics of bladder cancer (BC). Our objective was to correlate some of these IFs with BC progression and recurrence, identifying possible new diagnostic tools. Methods: We retrospectively analyzed 285 patients (79.8% male, 20.4% female; median age 73) who underwent transurethral resection of the bladder (TURB) between January 2016 and January 2022. The preoperative neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), systemic immune-inflammation index (SII), pan-immune-inflammation value (PIV), systemic inflammation response index (SIRI), and standard clinical variables were collected one month before TURB and evaluated as predictors of recurrence and progression. Patients were stratified using the Youden Index and ROC analysis. Cox regression models were applied to identify independent predictors. Results: High-grade tumors were present in 74.6% of cases, and 34% were recurrent. Carcinoma in situ was found in 5%. After 72 months, 53% underwent radical cystectomy, and 13.7% died within 5 years. The optimal cutoffs were PLR 139, SIRI 1.12, PIV 248.49, NLR 2, SII 327. Smoking, primary MIBC, age, and lymph node status were significantly associated with recurrence. Elevated PLR correlated with recurrence and T2 progression (p = 0.004). Higher SIRI, PIV, and PLR levels were significantly associated with lymphovascular invasion and nodal metastasis (p < 0.05). PLR was linked to recurrence in tumors ≥ 3 cm post-BCG (p = 0.004); high SIRI predicted recurrence within 48 months (p = 0.05). Conclusions: High PLR and SIRI levels were associated with recurrence. Our findings support the emerging role of IFs in predicting BC outcomes and suggest their potential inclusion in future prognostic models. Full article

Background/Objectives: Non-muscle-invasive bladder cancer (NMIBC) is a common form of bladder cancer with a significant risk of recurrence and progression, especially in intermediate- and high-risk patients. Bacillus Calmette–Guérin (BCG) therapy has been the gold standard, but its limitations have prompted the exploration of alternative therapies. This study aims to compare the long-term effectiveness of two such alternatives—hyperthermia-induced potentiation of mitomycin C (HIVEC) and electromotive drug administration (EMDA)—in preventing recurrence and progression in NMIBC patients. Methods: A prospective observational study was conducted at a Spanish center, including patients with intermediate- and high-risk NMIBC who were treated between August 2018 and December 2024. Participants were allocated to receive either HIVEC or EMDA based on their preferences. Both treatments followed a similar protocol, with an initial induction phase and maintenance sessions. Patient follow-up included regular cystoscopy, cytology, and imaging. Results: At 36 months, the disease-free survival rate was 62.4% for the HIVEC group and 67% for the EMDA group. Statistical analysis showed no significant difference between the two groups in terms of long-term efficacy. The adjusted hazard ratio for the treatment effect was 0.95, indicating comparable outcomes. Conclusions: Both HIVEC and EMDA demonstrate similar long-term efficacy in preventing recurrence and progression in intermediate- and high-risk NMIBC. These findings suggest that both treatments show promise as potential future options for managing NMIBC, providing clinicians with additional considerations based on patient characteristics and preferences. Further studies, particularly randomized controlled trials, are needed to confirm these results and optimize treatment protocols. Full article

Despite its immunogenic nature, bladder cancer (BCa) responds sub-optimally to FDA-approved immunotherapy. Background/Objectives: We have previously shown that natural killer (NK) cells are major contributors to overall patient survival in BCa. In our efforts to identify clinically approved agents that enhance NK cell activation, we identified eribulin, a microtubule destabilizer primarily used in breast cancer. Ongoing clinical trials are investigating the potential integration of eribulin into the standard of care in BCa; however, the mechanistic rationale for these trials remains unclear. Methods: Here, we explore the effects of low-dose eribulin on direct NK cell activation in vitro, including on primary patient samples, and in vivo utilizing multiple murine models. Flow cytometry and RNA sequencing were employed to identify the mechanism of NK cell activation by eribulin, which was associated with increased migration and cytotoxicity of NK cells against BCa cells. Results: We found that localized eribulin instillation significantly reduces bladder tumor burden and improves survival in primary BCa in an NK cell-dependent manner. Importantly, eribulin promoted the shift of patient-derived intratumoral NK cells towards an anti-tumor CD49a+ CD103+ NK subset (ieILC1-like) while diminishing the dysfunctional NR4A2-expressing CD49a NK subset. Moreover, it decreased the overall expression of exhaustion markers on NK cells, a pattern replicated in our murine models. Conclusions: These findings are paradigm-shifting given that chemotherapy is traditionally considered immunosuppressive. Our study reveals the novel effect of low-dose eribulin chemotherapy in inhibiting bladder tumor growth by enhancing anti-tumor NK cell immunity, challenging previous assumptions and opening new therapeutic approaches to improve antitumor immunity.

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. Full article
