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.

AbstractThe positive surgical margin (PSM) and biochemical recurrence (BCR) are two main factors associated with poor oncotherapeutic outcomes after prostatectomy. This is an Asian population study based on a single-surgeon experience to deeply investigate the predictors for PSM and BCR. We retrospectively included 419 robot-assisted radical prostatectomy cases. The number of PSM cases was 126 (30.1%), stratified as 22 (12.2%) in stage T2 and 103 (43.6%) in stage T3. Preoperative prostate-specific antigen (PSA) > 10 ng/mL (p = 0.047; odds ratio [OR] 1.712), intraoperative blood loss > 200 mL (p = 0.006; OR 4.01), and postoperative pT3 stage (p < 0.001; OR 6.901) were three independent predictors for PSM while PSA > 10 ng/mL (p < 0.015; hazard ratio [HR] 1.8), pT3 stage (p = 0.012; HR 2.264), International Society of Urological Pathology (ISUP) grade > 3 (p = 0.02; HR 1.964), and PSM (p = 0.027; HR 1.725) were four significant predictors for BCR in multivariable analysis. PSMs occurred mostly in the posterolateral regions (73.8%) which were associated with nerve-sparing procedures (p = 0.012) while apical PSMs were correlated intraoperative bleeding (p < 0.001). A high ratio of pT3 stage after RARP in our Asian population-based might surpass the influence of PSM on BCR. PSM was less significant than PSA and ISUP grade for predicting PSA recurrence in pT3 disease. Among PSM cases, unifocal and multifocal positive margins had a similar ratio of the BCR rate (p = 0.172) but ISUP grade > 3 (p = 0.002; HR 2.689) was a significant BCR predictor. These results indicate that PSA and pathological status are key factors influencing PSM and BCR.

e16162 Background: Outcomes in hospital based medicine are associated with the experience and availability of the medical staff, as mortality and morbidity rates increase each summer with new medical graduates. Hospital staff members are thought to be more fatigued and less available towards the end of the week and on weekends. However it is not known if there is a difference of outcomes based on the season or day of the week. We sought to identify if different seasons or surgical days of the week can predict poor outcomes and biochemical recurrence (BCR) in radical prostatectomy (RP). Methods: A retrospective analysis of the Columbia Urologic Oncology database was performed. 1865 consecutive men underwent RP from 1991 to 2008 by three surgeons. Data was collected in an institutional review board approved registry, with median follow up of 36 months. BCR was defined as two consecutive PSA levels > 0.2 ng/ml. Stratified cox regression methods were used to model the relationship between surgeon, preoperative variables, season, day of the week, and BCR. Winter was defined as December through February, spring as March through May, summer as June through August, and fall as September through November. Results: The mean age of the men undergoing RP was 61.2 years (37–79), with a mean preoperative PSA of 8.12. 424 men (22.7%) had positive surgical margins, and the mean estimated blood loss (EBL) was 1119cc. Patient age (p=0.68), preoperative PSA (p=0.32), EBL (p=0.51), and positive surgical margin rate (p=0.78) were not significantly different between each day. Men undergoing RP did not have different rates of BCR according to the day of the operation (p=0.58) or season (p=0.997). The particular season and day of the operation were not significantly associated with BCR, and were not independent predictors of BCR in a multivariable model after adjusting for preoperative PSA, Gleason sum, tumor stage, and surgeon. Conclusions: Patient surgical outcomes and BCR rates after RP are not associated with the particular season or day of the week of the procedure. These findings suggest that men undergoing RP do not need to be concerned about the particular season or day when scheduling the procedure. No significant financial relationships to disclose.
