Renal Cell Carcinoma with Venous Extension: Safety of Laparoscopic Surgery for Thrombus Levels I-IIIa.

Background: Novel studies are helping to consider minimally invasive surgery for treating patients with renal cell carcinoma and venous tumor thrombus. Evidence regarding its feasibility and safety is still sparse and does not include a subclassification for level III thrombi. We aim to compare the safety of laparoscopic vs open surgery in patients with levels I-IIIa thrombus. Materials and Methods: This is a cross-sectional comparative study using single-institutional data on adult patients treated surgically between June 2008 and June 2022. Participants were categorized into open and laparoscopic surgery groups. Primary outcome was difference in the incidence of 30-day major postoperative complications (Clavien-Dindo III-V) between groups. Secondary outcomes were differences in operative time, length of hospital stay, intraoperative blood transfusions, delta hemoglobin level, 30-day minor complications (Clavien-Dindo I-II), estimated overall survival, and progression-free survival between groups. A logistic regression model was performed including adjustment for confounding variables. Results: Overall, 15 patients in the laparoscopic group and 25 patients in the open group were included. Major complications occurred in 24.0% of patients within the open group and 6.7% of patients were treated laparoscopically (p = 0.120). Minor complications arose in 32.0% of patients treated with open surgery and in 13.3% of patients treated in the laparoscopic group (p = 0.162). Although not significant, there was a higher perioperative death rate within open surgery cases. The laparoscopic approach presented a crude odds ratio for major complications of 0.22 (95% confidence interval 0.02-2.1, p = 0.191) compared with open surgery. No differences were found between groups regarding oncologic outcomes. Conclusion: Laparoscopic approach for patients with venous thrombus levels I-IIIa seems to be as safe as open surgery.

Comparing open and robotic salvage radical prostatectomy after radiotherapy: predictors and outcomes.

INTRODUCTION: In the present study, we aim to provide more evidence about benefits of salvage radical prostatectomy (SRP). Our main objective is to assess prostatic-specific antigen control and postoperative urinary incontinence in open and robotic approaches as primary outcomes. MATERIALS AND METHODS: After the Institutional Review Board approval (IRB00010193), we retrospectively analyzed 76 consecutive patients who underwent open or robot-assisted SRP for locally relapsed prostate cancer between 2004 and 2019 at the Urology Department of Hospital Italiano de Buenos Aires, Argentina. Data were collected from our electronic medical record and prospective database.Postoperative variables, such as urinary incontinence, erectile function preservation, and vesicourethral anastomosis stricture development, were analyzed. RESULTS: Before SRP, 59 patients (76.6%) were treated with 3D external beam radiotherapy, 11 (14.3%) with brachytherapy, and 6 (7.8%) with intensity-modulated radiotherapy. Fifty patients underwent open SRP, and 26, robot-assisted SRP. Comparing surgical approaches, the global incontinence rate was 34.2% versus 9.1% in open versus robot-assisted approach, respectively (p: 0.01).Vesicourethral anastomosis stricture occurred in six patients (8.7%), all in the open approach group (p: 0.07). Five patients of 69 (7.2%) preserved erectile function with/without use of phosphodiesterase 5 inhibitors. Two patients in the open approach group needed blood transfusion. Estimated 2-year biochemical recurrence-free survival rate in the open approach group and robot-assisted group was 67% (95% confidence interval: 53.7-80.3) and 60.9% (95% confidence interval: 40.5-81.3), respectively, with no statistical difference (log-rank test p: 0.873). CONCLUSIONS: Robot-assisted SRP is a reliable procedure to treat local recurrences after external beam radiotherapy or brachytherapy, reducing the risk of anastomotic strictures and blood loss and improving continence outcomes.

Current Trends in Management of Renal Cell Carcinoma with Venous Thrombus Extension.

PURPOSE OF REVIEW: To review the evidence regarding the current trends in surgical management of renal cell carcinoma (RCC) with inferior vena cava (IVC) thrombosis. Recent published series have shown the role of minimally invasive surgery in IVC thrombectomy. This review article evaluates the present RCC with venous extent literature to assess the role of open and minimally invasive surgery in this scenario. RECENT FINDINGS: Robotic urological surgery has shown to have known benefits in radical prostatectomy, partial nephrectomy, and pyeloplasty. Recent published series showed feasibility of robotic IVC thrombectomy even for level IV cases. With growing number of robot-assisted and laparoscopic surgeries worldwide, there is a current tendency to treat this complex and challenging pathology with a minimally invasive approach, without compromising oncological outcomes.
