Comparison of Robot-Assisted Radical Prostatectomy and Open Radical Prostatectomy Outcomes: A Systematic Review and Meta-Analysis.

ABSTRACT:

Purpose

To systematically update evidence on the clinical efficacy and safety of robot-assisted radical prostatectomy (RARP) versus retropubic radical prostatectomy (RRP) in patients with prostate cancer.

Materials and methods

Electronic databases, including ovidMEDLINE, ovidEMBASE, the Cochrane Library, KoreaMed, KMbase, and others, were searched, collecting data from January 1980 to August 2013. The quality of selected systematic reviews was assessed using the revised assessment of multiple systematic reviews and the modified Cochrane Risk of Bias tool for non-randomized studies.

Results

A total of 61 studies were included, including 38 from two previous systematic reviews rated as best available evidence and 23 additional studies that were more recent. There were no randomized controlled trials. Regarding safety, the risk of complications was lower for RARP than for RRP. Among functional outcomes, the risk of urinary incontinence was lower and potency rate was significantly higher for RARP than for RRP. Regarding oncologic outcomes, positive margin rates were comparable between groups, and although biochemical recurrence (BCR) rates were lower for RARP than for RRP, recurrence-free survival was similar after long-term follow up.

Conclusion

RARP might be favorable to RRP in regards to post-operative complications, peri-operative outcomes, and functional outcomes. Positive margin and BCR rates were comparable between the two procedures. As most of studies were of low quality, the results presented should be interpreted with caution, and further high quality studies controlling for selection, confounding, and selective reporting biases with longer-term follow-up are needed to determine the clinical efficacy and safety of RARP.

Project description:Take Home Message Our review revealed a significantly higher annual volume of surgery per surgeon (AVSS), a higher percentage of low-risk patients, and lower rates of lymphadenectomy and complications for robot-assisted radical prostatectomy (RARP) compared to open and laparoscopic techniques. RARP showed better performance for all the perioperative variables studied except for operative time. Among all the outcomes, only AVSS was significantly correlated with complication rates. The AVSS required to achieve a target complication rate was significantly lower for RARP. Context The advantages of minimally invasive surgery for radical prostatectomy (RP) have been demonstrated in a number of systematic reviews (SRs). However, the rigorous study selection process for SR means that a lot of information can be excluded, leading to a very specific clinical scenario that is often unrepresentative of real life. Our new reverse SR methodology generates a heterogeneous population database that covers a wide range of clinical scenarios. Objective To compare perioperative surgical results and complications for open retropubic RP (RRP), laparoscopic RP (LRP), and robot-assisted RP (RARP) in a reverse SR. Evidence acquisition Eight databases were searched for SRs on RRP, LRP, or RARP between 2000 and 2020 (80 SRs). All references used in these SRs were captured for analysis (1724 articles). Perioperative outcomes and complications were compared among the RRP, LRP, and RARP approaches. Evidence synthesis We identified 559 (32.4%) reports on RRP, 413 (23.9%) on LRP, and 752 (43.7%) on RARP, involving 1 353 485 patients overall. RARP showed a significantly higher annual volume of surgery per surgeon (AVSS) in comparison to RRP and LRP (mean 64.29, 43.26, and 41.47, respectively), a higher percentage of low-risk patients (prostate-specific antigen <10 ng/ml, Gleason <7, stage <cT2), and a lower rate of lymphadenectomy, culminating in a lower complication rate (12.3% for RARP, 16.3% for LRP, 20.2% for RRP). Among all outcomes, only AVSS was significantly correlated with complication rates. An AVSS of 30, 95 and 95 surgeries/yr was required for RARP, LRP, and RRP, respectively, to obtain a complication rate of 12.3% (average for RARP). RARP showed better performance for all perioperative variables studied except for operative time (operative time: 199.8 vs 214.9 vs 169.5 min; estimated blood loss: 228.2 vs 408.0 vs 852.1 ml; blood transfusion rate: 2.8% vs 6.5% vs 19.8%; length of stay: 2.9 vs 5.7 vs 6.1 d; catheter time: 7.8 vs 8.5 vs 11.0 d for RARP vs LRP vs RRP). Conclusions Our reverse SR involved a wide real-life representative sample and reference values established in the literature and revealed that minimally invasive surgery had the best perioperative and complication results, especially RARP, which was associated with less complex cases, higher annual surgeon volume, and greater performance. Patient summary We used a wide sample representative of real-life surgical practice and reference values established in the literature for three techniques for removal of the prostate to guide patients and physicians in deciding the best surgical treatment for prostate cancer according to availability.

Project description:Robot-assisted radical prostatectomy (RARP) has been shown to achieve excellent oncological outcomes with a low rate of complications in patients with prostate cancer. However, data on RARP in renal transplant recipients (RT) are dispersed. A literature search was conducted through April 2023 using PubMed/Medline, Embase and Web of Science databases. The primary aim was to evaluate the safety, oncologic and clinical outcomes of RARP in RT recipients. The secondary aim was to identify surgical technique modifications required to avoid iatrogenic damage to the transplanted kidney. A total of 18 studies comprising 186 patients met the inclusion criteria. Age at the time of treatment ranged 43-79 years. Biopsy results showed a high prevalence of low- and intermediate-risk disease. Operative time ranged between 108.3 and 400 mins, while estimated blood loss ranged from 30 to 630 mL. Length of hospital stay ranged from 3 to 6 days whereas duration of catheterization was between 5 and 18 days. Perioperative complication rate was 17.1%. Overall positive surgical margin rate was 24.19%, while biochemical recurrence was observed in 10.21% (19/186 patients). Modifications to the standard surgical technique were described in 13/18 studies. Modifications in port placement were described in 7/13 studies and performed in 19/88 (21.6%) patients. Surgical technique for the development of the Retzius space was reported in 13/18 studies. Data on lymphadenectomy were reported in 15/18 studies. Bilateral lymphadenectomy was described in 3/18 studies and performed in 4/89 (4.5%) patients; contralateral lymphadenectomy was reported in 7/18 studies and performed in 41/125 (32.8%) patients. RARP in RTRs can be considered relatively safe and feasible. Oncological results yielded significantly worse outcomes in terms of PSM and BCR rate compared to the data available in the published studies, with an overall complication rate highly variable among the studies included. On the other hand, low graft damage during the procedure was observed. Main criticisms came from different tumor screening protocols and scarce information about lymphadenectomy techniques and outcomes among the included studies.

Project description:BackgroundRobotic-assisted radical prostatectomy(RARP) is widely used to surgically treat of localized prostate cancer. Among RARP, retzius-sparing techniques(RS-RARP) are implemented through douglas pouch, not the existing conventional approach(C-RARP). We conducted an updated systematic review and meta-analysis including recent published papers.Materials & methodsSystematic review was performed following the PRISMA guideline. PubMed, EMBASE, and Cochrane Library were searched up to August 2021. We conducted meta-analysis as follows; Participants, patients with biopsy-proven PCa; Interventions, Patients underwent C-RARP or RS-RALP; Outcomes, comparison of continence recovery rate, positive surgical margins(PSM), complication, operation time and estimated blood loss(EBL) included for analysis.ResultsThirteen studies with a total of 2917 patients were included for meta-analysis. Among them, three were randomized controlled trials (RCT) studies and the rest were non-RCT studies. Incontinence was analyzed with zero pad and safety pad, respectively. There showed a statistically significant advantage for RS-RARP in terms of continence recovery at 1 month(0 pad; OR 0.28, (0.16-0.47), safety-pad; OR 0.12 (0.07-0.22), p<0.001), as well as at 3 months(0 pad; OR 0.31 (0.18-0.53), safety-pad; OR 0.23 (0.14-0.40) p<0.001), 6 months(0 pad; OR 0.29 (0.17-0.51), safety-pad; OR 0.13 (0.06-0.27), p<0.001). And after 12 months, RS-RARP showed better results only in the safety-pad(0 pad; OR 0.64 (0.35-1.18), p = 0.15, safety-pad; OR 0.12 (0.04-0.36), p<0.001). In PSM, there was no statistical difference between two group at overall stage, but RS-RARP was observed to be higher than C-RARP in pT3 subgroup analysis(OR 0.74 (0.55-0.99), p = 0.047) (Fig 1). Whereas, there was no significant difference between the two groups in complication, operation time, and EBL.ConclusionsOur analysis showed that RS-RARP is superior about early continence recovery than C-RARP. However, RS-RARP showed relatively high PSM in locally advanced PCa of pT3 or above. Therefore, although RS-RARP has few advantages about functional outcomes, we think that caution should be exercised when approaching patients with high-risk local diseases.

Project description:ObjectivesTo describe in detail the techniques for transvesical robot-assisted radical prostatectomy (RARP) using the da Vinci Si/Xi system (Intuitive Surgical, Sunnyvale, CA, USA) and to evaluate functional and oncological outcomes in 35 patients with prostate cancer.Patients and methodsThirty-five patients with localized prostate cancer were enrolled for transvesical RARP. The patients' preoperative data (mean ± sd age 63.4 ± 8.1 years, body mass index 28.6 ± 5.3 kg/m2 , total prostate-specific antigen 10.8 ± 4.9 ng/mL and prostate volume 30.6 ± 14.4 mL, and median [interquartile range {IQR}] biopsy Gleason score 6 [6-7], and International Index of Erectile Function [IIEF]-5 score 18 [16-20]) were collected. Preoperative assessment revealed 28 cases of cT2a and seven cases of cT2b disease. All patients were continent preoperatively (defined as no pad required or one dry pad per day as a precaution). Surgical results and peri-operative complications were assessed. All patients were followed up for at least 12 months postoperatively.ResultsThe mean operating time was 150 ± 35 min. Estimated blood loss was 100 ± 45 mL. Urinary infection was noted in one patient and managed with levofloxacin. Another patient complained of nocturia on postoperative day 14, which was relieved with solifenacin succinate. Urethral catheters were removed on postoperative day 7. Thirty-two patients achieved immediate urinary continence, with three patients returning to full continence on postoperative day 14. Postoperative pathology confirmed 24 pT2a cases, nine pT2b cases and two pT2c cases (median [IQR] Gleason score 6 [6-7]). Positive surgical margins were found in four patients (11.4%). No urethral stricture or urinary leakage was noted on urethrocystography taken 3 months after surgery. Urodynamic studies were performed preoperatively and 6 months after surgery: median (IQR) maximum urinary flow 12.2 (10.2-14.9) vs 13.7 (10.1-15.0) mL/s; bladder capacity 385.3 (351.3-410.2) vs 370.2 (330.1-395.4) mL; and voiding phase detrusor contractility 38.5 (27.8-42.3) vs 35.6 (28.3-41.3) mmH2 O, respectively. During a minimum of 12 months of follow-up, no biochemical recurrence was noted in any patient. The median (IQR) IIEF-5 score was 17 (16-19).ConclusionsThe transvesical approach is a valid alternative to RARP in selected patients, providing promising postoperative urinary continence. Long-term functional and oncological results require further investigation.
