Background/Objectives: Artificial intelligence (AI) tools, particularly large language models (LLMs) such as ChatGPT-4o, are gaining prominence in medicine. While their diagnostic capabilities have been explored across various oncologic domains, their role in clinical decision-making within multidisciplinary tumor boards (MTBs) remains largely unexamined in urologic oncology. This study evaluates the performance of ChatGPT-4o as a decision-support tool in a real-world MTB setting by comparing its recommendations with those of expert clinicians. Materials and Methods: A retrospective study was conducted using 98 anonymized clinical cases discussed by a urologic MTB between June 2024 and February 2025. An independent urologist entered the same cases into ChatGPT-4o using a standardized prompt replicating real-world presentation. Two certified urologists independently assessed the model’s responses. Agreement was analyzed overall and by tumor type, disease stage, clinical context, and treatment strategy. Results: ChatGPT-4o fully agreed with the MTB in 56.1% of cases, was correct but incomplete in 23.5%, and provided partially accurate but flawed recommendations in 18.4%. Overall concordance between ChatGPT-4o and the MTB yielded a Cohen’s kappa of 0.61, indicating moderate-to-good agreement. Discrepancies were most common in metastatic prostate cancer, often due to misclassification of tumor burden or errors in treatment sequencing. Highest agreement rates were observed in bladder and renal tumors, and in standardized therapeutic scenarios such as radiotherapy. Conclusions: ChatGPT-4o demonstrated moderate alignment with expert MTB decisions and performed best in well-defined clinical contexts. While it cannot replace multidisciplinary expertise, it may serve as a supportive tool to enhance access to standardized oncologic care.

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.

Background/Objectives: Non-muscle invasive bladder cancer (NMIBC) is characterized by high recurrence rates, requiring frequent diagnostic and therapeutic interventions. This study evaluates the feasibility, safety, oncological outcomes, and economic impact of implementing an in-office laser bladder tumor fulguration protocol. Methods: A descriptive, longitudinal study was conducted between 2020 and 2025 on 65 patients with recurrent NMIBC. Procedures were performed in an outpatient setting under local anesthesia using a flexible cystoscope and a Holmium:YAG (Ho:YAG) laser. The primary endpoint was recurrence-free survival. Secondary endpoints included complication rates (Clavien–Dindo) and a cost-analysis comparison with conventional transurethral resection of the bladder (TURBT). Results: The mean age was 69.4 years, with 89.2% of patients classified as ASA ≥ 2. After a median follow-up of 20.3 months, the recurrence rate was 33.8%, with 0% progression. Most procedures (95.4%) had no complications; only 4.6% presented Clavien–Dindo grade 1 events. Adjuvant mitomycin C was administered in 93.8% of cases. The cost analysis demonstrated substantial economic advantages, with costs reduced by 89.7% versus the 24 h admission model and 82.1% versus the day-surgery model according to regional health-system tariffs. Conclusions: In-office laser fulguration is a safe, effective, and economically sustainable alternative to traditional TURBT for selected low-risk recurrences. It optimizes hospital resources, minimizes anesthetic risk in comorbid patients, and maintains favorable oncological control.

Background/Objectives Robot-assisted radical prostatectomy (RARP) is widely used in contemporary prostate cancer surgery, although surgeons enter robotic practice through heterogeneous training pathways. This study aimed to compare early oncological and functional outcomes after RARP between two experienced robotic surgeons with different surgical backgrounds once the learning curve had been surpassed. Methods: We conducted a retrospective, consecutive, single-center study including patients undergoing RARP after completion of the learning curve (>40 cases) by two experienced robotic surgeons with different surgical backgrounds. Baseline characteristics, perioperative variables, and early oncological and functional outcomes were compared between surgeons. Pentafecta achievement was assessed as an exploratory composite outcome. Appropriate non-parametric and categorical statistical tests were applied. Results: Ninety-three patients were included (55 operated on by surgeon A and 38 by surgeon B). Preoperative clinical and pathological characteristics were largely comparable between groups, except for prostate volume. Median operative time was significantly shorter for surgeon A (70 vs. 120 minutes, p < 0.001). Postoperative morbidity was low, with no major complications and no differences in length of hospital stay. At 6 months, urinary continence and erectile function recovery rates were high and comparable between surgeons. Oncological outcomes, including positive surgical margin rates and biochemical recurrence, did not differ significantly, although recurrence events were infrequent and follow-up was limited. Overall pentafecta achievement was modest and similar between groups (23.6% vs. 21.1%, p = 0.77), with positive surgical margins emerging as the main limiting factor. Conclusions: In this exploratory post–learning curve analysis, early oncological and functional outcomes after RARP were similar between surgeons with different surgical backgrounds. These findings should be interpreted cautiously and considered hypothesis-generating.

Multiple myeloma is a hematological malignancy characterized by clonal proliferation of plasma cells, usually confined to the bone marrow. Extramedullary disease (EMD) occurs in 7–18% of patients during the disease course and is associated with poor prognosis. Among extramedullary sites, testicular involvement is extremely rare, with an incidence of less than 2%. We present a rare case of testicular plasmacytoma as the first manifestation of systemic multiple myeloma, highlighting its imaging features and clinical implications.
