Positive Surgical Margin and Perioperative Complication Rates of Primary Surgical Treatments for Prostate Cancer: A Systematic Review and Meta-Analysis Comparing Retropubic, Laparoscopic, and Robotic Prostatectomy

103 Background: There is no clear evidence to support one form of surgical approach over another with regards radical prostatectomy. The aim of this study was to analyze the literature available between 2002 and 2008 and compare positive surgical margin and complication rates for open retropubic, laparoscopic, and robotic radical prostatectomy. Methods: A total of 110,016 patients formed the basis of this meta-analysis, representing the largest compilation of radical prostatectomy patients in the literature. Summary data were abstracted on year of publication, pre-operative patient characteristics, positive surgical margins, estimated blood loss, blood transfusions, conversions, length of hospital stay, and total intra- and peri-operative complications, with a further 21 individual perioperative complications selected a priori for abstraction and analysis. Results: The open and laparoscopic surgical groups had similar overall positive surgical margin rates, with the robotic group having lower rates. Both minimally invasive approaches showed significantly lower estimated blood loss and rate of blood transfusions, and a shorter length of hospital stay when compared to an open approach. A further decrease in these parameters was seen when robotic assistance was used. Total complication rates were highest for the open approach, intermediate for the laparoscopic cohort, and lowest for the robotic group. For the individual complication analysis, the rates for death, readmission, reoperation, ureteral, bladder, and rectal injury, ileus, pneumonia, fistula, and wound infection showed significant differences between groups. Conclusions: Robotic assisted laparoscopic radical prostatectomy has overall lower perioperative morbidity and improved early oncologic outcomes compared to conventional laparoscopic or open approaches. Further studies comparing longer term oncologic and functional outcomes, as well as cost-benefit comparisons are needed before making recommendations for or against a specific type of surgery.

The Impact

Background: Single-port robotic-assisted radical prostatectomy has been reported as a safe and feasible technique. However, recent studies comparing single-port versus multiple-port robotic radical prostatectomy have displayed conflicting results. Objectives: To investigate the benefit of single-port robotic radical prostatectomy and the impact on outcome compared to multiple-port robotic radical prostatectomy. Methods: Based on PRISMA and AMSTAR criteria, a systematic review and meta-analysis were carried out. Finally, we considered the controlled studies with two cohorts (one cohort for single-port RARP and the other cohort for multiple-port RARP). For statistical analysis, Review Manager (RevMan) software version 5.4 was used. The Newcastle-Ottawa Scale was employed to assess the risk of bias. Results: Five non-randomized controlled studies with 666 patients were included. Single-port robotic radical prostatectomy was associated with shorter hospital stays. Only 60.6% of single-port patients (109/180) required analgesia compared to 90% (224/249) of multiple-port patients (Z = 3.50; p = 0.0005; 95% CI 0.07:0.47). Opioid administration was also significantly lower in single-port patients, 26.2% (34/130) vs. 56.6% (77/136) (Z = 4.90; p < 0.00001; 95% CI 0.15:–0.44) There was no significant difference in operative time, blood loss, complication rate, positive surgical margin rate, or continence at day 90. Conclusion: The available data on single-port robotic radical prostatectomy is very limited. However, it seems comparable to the multiple-port platform in terms of short-term outcomes when performed with expert surgeons. Single-port prostatectomies might provide a shorter hospital stay and a lower requirement for opioids; however, randomized trials with long-term follow-up are mandatory for valid comparisons.
