- Purpose To evaluate urinary continence (UC) recovery and oncological outcomes in different risk-groups after robot-assisted radical prostatectomy (RALP) and open retropubic radical prostatectomy (RRP). Patients and methods We analysed 2650 men with prostate cancer from seven open (n = 805) and seven robotic (n = 1845) Swedish centres between 2008 and 2011 in a prospective non-randomised trial, LAPPRO. UC recovery was defined as change of pads less than once in 24 h. Information was collected through validated questionnaires. Rate of positive surgical margins (PSM) and biochemical recurrence (BCR), defined as prostate-specific antigen (PSA) > 0.25 mg/ml, were recorded. We stratified patients into two risk groups (low-intermediate and high risk) based on the D'Amico risk classification system. Result Among men with high-risk prostate cancer, we found significantly higher rates of UC recovery up to 24 months after RRP compared to RALP (66.1% vs 60.5%) RR 0.85 (CI 95% 0.73-0.99) while PSM was more frequent after RRP compared to RALP (46.8% vs 23.5%) RR 1.56 (CI 95% 1.10-2.21). In the same group no significant difference was seen in BCR. Overall, however, BCR was significantly more common after RRP compared to RALP at 24 months (9.8% vs 6.6%) RR 1.43 (Cl 95% 1.08-1.89). The limitations of this study are its non-randomized design and the relatively short time of follow-up. Conclusions Our study indicates that men with high-risk tumour operated with open surgery had better urinary continence recovery but with a higher risk of PSM than after robotic-assisted laparoscopic surgery. No significant difference was seen in biochemical recurrence.

- Purpose: In addition to incisional hernia, inguinal hernia is a recognized complication to radical retropubic prostatectomy. To compare the risk of developing inguinal and incisional hernias after open radical prostatectomy compared to robot-assisted laparoscopic prostatectomy. Method: Patients planned for prostatectomy were enrolled in the prospective, controlled LAPPRO trial between September 2008 and November 2011 at 14 hospitals in Sweden. Information regarding patient characteristics, operative techniques and occurrence of postoperative inguinal and incisional hernia were retrieved using six clinical record forms and four validated questionnaires. Results: 3447 patients operated with radical prostatectomy were analyzed. Within 24 months, 262 patients developed an inguinal hernia, 189 (7.3%) after robot-assisted laparoscopic prostatectomy and 73 (8.4%) after open radical prostatectomy. The relative risk of having an inguinal hernia after robot-assisted laparoscopic prostatectomy was 18% lower compared to open radical retropubic prostatectomy, a non-significant difference. Risk factors for developing an inguinal hernia after prostatectomy were increased age, low BMI and previous hernia repair. The incidence of incisional hernia was low regardless of surgical technique. Limitations are the non-randomised setting. Conclusions: We found no difference in incidence of inguinal hernia after open retropubic and robot-assisted laparoscopic radical prostatectomy. The low incidence of incisional hernia after both procedures did not allow for statistical analysis. Risk factors for developing an inguinal hernia after prostatectomy were increased age and BMI.

- Background: Conclusive evidence of superiority in oncological outcome for robotassisted laparoscopic prostatectomy (RALP) over retropubic radical prostatectomy (RRP) is lacking. Objective: To compare RALP and RRP regarding recurrent disease and to report the mortality rate 6 yr after surgery. Design, setting, and participants: A total of 4003 men with localized prostate cancer were enrolled between 2008 and 2011 in Laparoscopic Prostatectomy Robot Open (LAPPRO)- a prospective, controlled, nonrandomized trial performed at 14 Swedish centers. Outcome measurements and statistical analysis: Data were collected at visits and by patient questionnaires at 3, 12, and 24 mo, and through a structured telephone interview at 6 yr. Cause of death was retrieved from the National Cause of Death Register in Sweden. The modified Poisson regression approach was used for analyses. Results and limitations: After adjustment for patient-, tumor-, and surgeon-related confounders, no statistically significant difference was observed between RALP and RRP in biochemical recurrence rate (14 vs 16%, relative risk [RR] 0.77, 95% confidence interval [CI] 0.56-1.06) or in not cured endpoint (22% vs 23%, RR 0.82, 95% CI 0.6-1.11). Stratified by D'Amico risk group, a significant benefit for RALP existed for recurrent disease in high-risk patients (RR 0.47, 95% CI 0.26-0.86, p = 0.02). All-cause mortality was 3% (n = 96). Prostate cancer-specific mortality was 0.6% (n = 21) overall, 0.3% (n = 8) after RALP, and 1.5% (n = 13) after RRP. The nonrandomized design is a limitation. Conclusions: No significant difference was observed for cancer recurrence rate between RALP and RRP 6 yr after surgery. However, in a subgroup analysis, we found a significant benefit for RALP regarding recurrence rate in the high-risk group. Larger studies with longer follow-up are needed to make a firm conclusion and to evaluate a possible survival benefit. Patient summary: In general, the oncological outcome is comparable between robotic and open radical prostatectomy 6 yr after surgery. For high-risk patients, our findings indicate that there is an advantage for robotics, but further studies with longer follow-up time is needed to make a firm conclusion.
