Background: Prostate cancer (PCa) imposes a substantial global health burden, with robot-assisted radical prostatectomy (RARP) established as the gold standard for localized disease. While da Vinci® Xi maintains market dominance, Toumai® MT-1000 offers a potentially cost-competitive alternative lacking prospective validation. Objective: To evaluate perioperative safety, oncologic quality (primary endpoint: positive surgical margins), early functional recovery (continence), and surgeon learning curve between Toumai® MT-1000 (T-RARP) and da Vinci® Xi RARP (DV-RARP) performed in high-volume European practice. Materials and Methods: This is a prospective single-center comparative study carried out at Policlinico Gemelli, Rome (May–November 2025), enrolling 80 patients with localized or locally advanced PCa, elected for radical prostatectomy and casually allocated to receive surgery with Toumai or the da Vinci robotic platform. The primary endpoint was the comparison of positive surgical margin (PSM) rates. Secondary endpoints included the comparison of operative time (skin-to-skin), estimated blood loss, length of hospital stay, 45-day postop outcomes, specifically Clavien–Dindo complications, urinary continence recovery (0–1 pad/day), and IIEF-5 scores. Learning curve was evaluated through the cumulative summation (CUSUM) analysis of operative times and linear regression of operative times (n = 80 cases). The analyses used STATA 19 with two-sided tests at p < 0.05 significance. Results: Baseline characteristics showed balance between cohorts (p > 0.05 for most covariates). Perioperative outcomes proved equivalent: median operative time (OT) was 192.5 min (IQR 165–230) for Toumai® versus 183.5 min (IQR 147–225) for da Vinci® Xi (p = 0.38); estimated blood loss (EBL) was 150 mL in both groups (p = 0.87); length of hospital stay (LOS) was 2 days in both groups (p = 0.92). PSM rates were identical at 17.5% (p = 0.79). Continence recovery reached 72.5% versus 80% (p = 0.43). Complications (Clavien–Dindo ≥ II) occurred in 7.5% versus 12.5% of cases (p = 0.45). The CUSUM analysis demonstrated operative time proficiency after only four procedures; operative time regression showed no significant trend (p = 0.38). Conclusions: Toumai® MT-1000 demonstrates similar performance to da Vinci® Xi across different RARP quality metrics, with no detectable learning curve for surgeons previously experienced with da Vinci. These findings support a safe integration of cost-effective platforms into clinical practice, pending multicenter randomized confirmation.

Minimally invasive ablative therapies have emerged as effective and safe alternate approach for the management of renal cell carcinoma (RCC), particularly in patients who are ineligible for surgery due to comorbidities or high operative risk. Techniques such as radiofrequency ablation (RFA), microwave ablation (MWA), cryoablation (CA), and high-intensity focused ultrasound (HIFU) offer kidney-sparing treatment with reduced morbidity. Current evidence suggests that for cT1a tumors (<4 cm), thermal ablation achieves technical success rates exceeding 95%, with local recurrence rates ranging from 1% to 9% and major complication rates generally below 5–7%. RFA is particularly suitable for small peripheral tumors, MWA enables rapid and deeper heating for larger or more vascular lesions, and CA provides precise control near critical structures. HIFU remains largely experimental with limited clinical applicability. Overall, these strategies demonstrate favorable oncological outcomes, emphasizing the importance of careful patient selection, multidisciplinary evaluation, and further studies to refine technique-specific indications and integration with systemic therapies.

Background and Objective: Liquid biopsy has transformed the management of advanced prostate cancer, yet its clinical role in non-metastatic disease remains uncertain. Conventional biomarkers such as PSA, imaging, and pathology have limited ability to capture minimal residual disease and biological aggressiveness. The objective of this review was to critically evaluate the current evidence on circulating tumor cells (CTCs) and circulating tumor DNA (ctDNA) in non-metastatic prostate cancer, focusing on feasibility, prognostic value, and potential clinical applications. Methods: A narrative review of PubMed-indexed original studies evaluating liquid biopsy in clinically localized or non-metastatic prostate cancer was performed. Eligible studies included patients treated with curative-intent local therapy or experiencing biochemical recurrence without radiologic metastases. Study designs were predominantly prospective or retrospective observational cohorts. Liquid biopsy analytes included CTCs and ctDNA assessed from peripheral blood plasma using EpCAM-based enrichment, targeted next-generation sequencing, whole-genome sequencing, or ultra-sensitive tumor-informed assays. Primary outcomes included detection rates, associations with clinicopathologic features, biochemical recurrence, metastasis-free survival, and overall survival. Key Findings and Limitations: Across 11 studies, CTC detection using EpCAM-based platforms was infrequent in localized disease and biochemical recurrence and showed limited prognostic value (10–11% in preoperative settings). In contrast, ctDNA was detectable in a minority of patients but consistently identified biologically aggressive disease and a higher risk of recurrence when present, particularly using tumor-informed ultra-sensitive assays. Limitations include low detection rates, heterogeneous methodologies, small sample sizes, and predominantly exploratory study designs. Conclusions and Clinical Implications: Currently, its most promising application is not broad screening, but as a selective, biology-driven tool for detecting minimal residual disease and refining risk assessment. CtDNA acts as a biological risk modifier, potentially guiding the escalation or de-escalation of adjuvant therapy. However, prospective biomarker-driven trials are required to validate these strategies before routine clinical implementation.
