Protocol of the Italian Radical Cystectomy Registry (RIC): a non-randomized, 24-month, multicenter study comparing robotic-assisted, laparoscopic, and open surgery for radical cystectomy in bladder cancer

Bladder cancer is the ninth most common type of cancer worldwide. In the past, radical cystectomy via open surgery has been considered the gold-standard treatment for muscle invasive bladder cancer. However, in recent years there has been a progressive increase in the use of robot-assisted laparoscopic radical cystectomy. The aim of the current project is to investigate the surgical, oncological, and functional outcomes of patients with bladder cancer who undergo radical cystectomy comparing three different surgical techniques (robotic-assisted, laparoscopic, and open surgery). Pre-, peri- and post-operative factors will be examined, and participants will be followed for a period of up to 24\u2009months to identify risks of mortality, oncological outcomes, hospital readmission, sexual performance, and continence

Protocol of the Italian Radical Cystectomy Registry (RIC): a non-randomized, 24-month, multicenter study comparing robotic-assisted, laparoscopic, and open surgery for radical cystectomy in bladder cancer

Background: Bladder cancer is the ninth most common type of cancer worldwide. In the past, radical cystectomy via open surgery has been considered the gold-standard treatment for muscle invasive bladder cancer. However, in recent years there has been a progressive increase in the use of robot-assisted laparoscopic radical cystectomy. The aim of the current project is to investigate the surgical, oncological, and functional outcomes of patients with bladder cancer who undergo radical cystectomy comparing three different surgical techniques (robotic-assisted, laparoscopic, and open surgery). Pre-, peri- and post-operative factors will be examined, and participants will be followed for a period of up to 24 months to identify risks of mortality, oncological outcomes, hospital readmission, sexual performance, and continence. Methods: We describe a protocol for an observational, prospective, multicenter, cohort study to assess patients affected by bladder neoplasms undergoing radical cystectomy and urinary diversion. The Italian Radical Cystectomy Registry is an electronic registry to prospectively collect the data of patients undergoing radical cystectomy conducted with any technique (open, laparoscopic, robotic-assisted). Twenty-eight urology departments across Italy will provide data for the study, with the recruitment phase between 1st January 2017-31st October 2020. Information is collected from the patients at the moment of surgical intervention and during follow-up (3, 6, 12, and 24 months after radical cystectomy). Peri-operative variables include surgery time, type of urinary diversion, conversion to open surgery, bleeding, nerve sparing and lymphadenectomy. Follow-up data collection includes histological information (e.g., post-op staging, grading, and tumor histology), short- and long-term outcomes (e.g., mortality, post-op complications, hospital readmission, sexual potency, continence etc). Discussion: The current protocol aims to contribute additional data to the field concerning the short- and long-term outcomes of three different radical cystectomy surgical techniques for patients with bladder cancer, including open, laparoscopic, and robot-assisted. This is a comparative-effectiveness trial that takes into account a complex range of factors and decision making by both physicians and patients that affect their choice of surgical technique.

Trifecta results in Retzius-sparing robotic radical prostatectomy: results of a high-volume center

Aim: We aimed to evaluate trifecta outcomes after Retzius-sparing robot-assisted radical prostatectomy (rs-RARP).Methods: We evaluated 1488 patients who had undergone rs-RARP at our institution from 2011 to 2019. All patients filled out questionaries for functional outcomes before surgery, and only patients with baseline continence and IIEF-5 scores of > 16 were included. Biochemical recurrence (BCR) was defined as two consecutive prostatic specific antigen levels of > 0.2 ng/mL after rs-RARP. Postoperative continence was defined as the use of no pads. Potency was defined as the ability to achieve erections for sexual intercourse, with or without phosphodiesterase-5 (PDE-5) inhibitors. A multivariable logistic regression model was performed to identify predictors of trifecta outcome.Results: In total, 1240 patients were included in the analysis. During the 24-month follow-up time, 149 patients (11.9%) harbored BCR. Urinary continence was observed in 981 patients (79.5%), while 171 (13.8%) still used a safety pad daily after 24 months. Sexual potency was reported in 643 patients (51.9%), of whom 379 (30.6%) had spontaneous erections and 264 (21.3%) used a PDE-5 inhibitor. Overall, the trifecta outcome was reached by 42.1% of the study’s population. The trifecta outcome was easily reached by younger patients and patients who underwent a full nerve-sparing (NS) prostatectomy. In the multivariable model, age [odds ratio (OR) = 0.89; 95% confidence interval (CI): 0.84-0.90; P < 0.01] and type of NS surgery [partial NS (OR = 3.34; 95%CI: 1.01-11; P = 0.04) full NS (OR = 4.57; 95%CI: 1.86-12; P < 0.01)] resulted as independent predictors.Conclusion: rs-RARP is associated with optimal trifecta outcome rate. Age and NS technique are independent predictors of trifecta outcomes

Robotic-assisted, laparoscopic, and open radical cystectomy: surgical data of 1400 patients from The Italian Radical Cystectomy Registry on intraoperative outcomes

In selected cases of high-risk non-muscle invasive bladder cancer (NMIBC) or muscle invasive bladder cancer (MIBC) the optimal oncological is reached with radical cystectomy (RC) : moreover, it is considered the gold standard. This surgery is complex, with significant morbidity, and it essentially consists of two phases, the destructive phase (removal of the bladder and the lymph nodes) and the reconstructive phase (urinary diversion), and each step is prone to complications. Therefore, RC is preferably performed in referral centers where the experience of the surgeon and the facilities allow to minimize the burden of this complex surgery. Open RC (ORC) has represented the gold standard approach for a long time; recently, the increased introduction of new technologies has led to minimally invasive approaches such as laparoscopic RC (LRC), and robotic-assisted RC (RARC) becoming more and more applied in this field. Surely, RARC represents a challenging procedure that can be improved with specific training and a skilled robotic team. However, RARC is a suitable technique for both older and younger patients and has shown promising rates of peri-operative and short-term outcomes compared to ORC: lower rates of minor perioperative complications, decreased blood loss and transfusion rate, faster gastrointestinal recovery, and shorter length of stay. Despite several studies reporting comparable long-term oncological outcomes for RARC versus ORC, data on the long-term functional outcomes is sparse. No studies have directly compared urinary continence or sexual potency in patients receiving neobladder after RARC versus ORC. Not least, the economic burden of RARC is heavier than open surgery due to higher supply costs, but an effective cost-effective analysis is lacking to date. In a systematic review, Novara et al. demonstrated the safety, acceptable operative time other than relatively lower estimated blood loss (EBL), and relatively low transfusion rate for RARC compared to ORC and LRC. Most intra-abdominal surgical procedures in urology are now performed robotically worldwide. The transition is gradual due to the high cost of the technology and the associated learning curve. The hope is that with more competition in the robotic technology space, the advent of new robotic companies will bring the overall costs down and will reduce the robotic technology healthcare disparities. The Italian Radical Cystectomy Registry (Registro Italiano Cistectomie – RIC) Protocol aimed to accurately and comprehensively assess the outcomes of RC in order to improve current clinical knowledge. The aim of this study was to analyse intraoperative outcomes of a multicenter series of patients treated with RC for bladder cance

The Oncological and Functional Prognostic Value of Unconventional Histology of Prostate Cancer in Localized Disease Treated with Robotic Radical Prostatectomy: An International Multicenter 5-Year Cohort Study

This is the accepted manuscript version of an article which has been published in final form at https://doi.org/10.1016/j.euo.2023.12.006Background and objective The impact of prostate cancer of unconventional histology (UH) on oncological and functional outcomes after robot-assisted radical prostatectomy (RARP) and adjuvant radiotherapy (aRT) receipt is unclear. We compared the impact of cribriform pattern (CP), ductal adenocarcinoma (DAC), and intraductal carcinoma (IDC) in comparison to pure adenocarcinoma (AC) on short- to mid-term oncological and functional results and receipt of aRT after RARP. Methods We retrospectively collected data for a large international cohort of men with localized prostate cancer treated with RARP between 2016 and 2020. The primary outcomes were biochemical recurrence (BCR)-free survival, erectile and continence function. aRT receipt was a secondary outcome. Kaplan-Meier survival and Cox regression analyses were performed. Key findings and limitations A total of 3935 patients were included. At median follow-up of 2.8 yr, the rates for BCR incidence (AC 10.7% vs IDC 17%; p < 0.001) and aRT receipt (AC 4.5% vs DAC 6.3% [p = 0.003] vs IDC 11.2% [p < 0.001]) were higher with UH. The 5-yr BCR-free survival rate was significantly poorer for UH groups, with hazard ratios of 1.67 (95% confidence interval [CI] 1.16–2.40; p = 0.005) for DAC, 5.22 (95% CI 3.41–8.01; p < 0.001) for IDC, and 3.45 (95% CI 2.29–5.20; p < 0.001) for CP in comparison to AC. Logistic regression analysis revealed that the presence of UH doubled the risk of new-onset erectile dysfunction at 1 yr, in comparison to AC (grade group 1-3), with hazard ratios of 2.13 (p < 0.001) for DAC, 2.14 (p < 0.001) for IDC, and 2.01 (p = 0.011) for CP. Moreover, CP, but not IDC or DAC, was associated with a significantly higher risk of incontinence (odds ratio 1.97; p < 0.001). The study is limited by the lack of central histopathological review and relatively short follow-up. Conclusions and clinical implications In a large cohort, UH presence was associated with worse short- to mid-term oncological outcomes after RARP. IDC independently predicted a higher rate of aRT receipt. At 1-yr follow-up after RP, patients with UH had three times higher risk of erectile dysfunction post RARP; CP was associated with a twofold higher incontinence rate. Patient summary Among patients with prostate cancer who undergo robot-assisted surgery to remove the prostate, those with less common types of prostate cancer have worse results for cancer control, erection, and urinary continence and a higher probability of receiving additional radiotherapy after surgery.Peer reviewe

Contemporary Techniques of Prostate Dissection for Robot-assisted Prostatectomy

BACKGROUND: Over the years, several techniques for performing robot-assisted prostatectomy have been implemented in an effort to achieve optimal oncological and functional outcomes. OBJECTIVE: To provide an evidence-based description and video-based illustration of currently available dissection techniques for robotic prostatectomy. DESIGN, SETTING, AND PARTICIPANTS: A literature search was performed to retrieve articles describing different surgical approaches and techniques for robot-assisted radical prostatectomy (RARP) and to analyze data supporting their use. Video material was provided by experts in the field to illustrate these approaches and techniques. SURGICAL PROCEDURE: Multiple surgical approaches are available: extraperitoneal, transvesical, transperitoneal posterior, transperitoneal anterior, Retzius sparing, and transperineal. Surgical techniques for prostatic dissection sensu strictu are the following: omission of the endopelvic fascia dissection, bladder neck preservation, incremental nerve sparing by means of an antegrade or retrograde approach, and preservation of the puboprostatic ligaments and dorsal venous complex. Recently, techniques for total or partial prostatectomy have been described. MEASUREMENTS: Different surgical approaches and techniques for robotic prostatectomy have been analyzed. RESULTS AND LIMITATIONS: Two randomized controlled trials evaluating the extraperitoneal versus the transperitoneal approach have demonstrated similar results. Level I evidence on the Retzius-sparing approach demonstrated earlier return to continence than the traditional anterior approach. The question whether Retzius-sparing RARP is associated with a higher rate of positive surgical margins is still open due to the intrinsic bias in terms of surgical expertise in the available comparative studies. This technique also offers an advantage in patients who have received kidney transplantation. Retrospective evidence suggests that the more the anatomical dissection (eg., more periprostatic tissue is preserved), the better the functional outcome in terms of continence. Yet, two randomized controlled trials evaluating the different techniques of dissection have so far been produced. Partial prostatectomies should not be offered outside clinical trials. CONCLUSIONS: Several techniques and approaches are available for prostate dissection during RARP. While the Retzius-sparing approach seems to provide earlier return to continence than the traditional anterior transperitoneal approach, no technique has been proved to be superior to other(s) in terms of long-term outcomes in randomized studies. PATIENT SUMMARY: We have summarized available approaches for the surgical treatment of prostate cancer. Specifically, we described the different techniques that can be adopted for the surgical removal of the prostate using robotic technology
