- Background: Reports on possible benefits for continence with nerve-sparing (NS) radical prostatectomy have expanded the indications beyond preservation of erectile function. It is unclear whether NS surgery affects oncological outcomes. Objective: To determine whether the degree of NS during radical prostatectomy influences oncological outcomes. Design, setting, and participants: Of 4003 patients enrolled in a prospective, controlled trial comparing open and robotic radical prostatectomy during 2008–2011, we evaluated 2401 patients who received robotic radical prostatectomy at seven Swedish centres. Patients were followed for 8 yr. Outcome measurements and statistical analysis: Data for recurrence and positive surgical margin status were assessed using validated patient questionnaires, patient interviews, and clinical record forms before and at 3, 12, and 24 mo and 6 and 8 yr after surgery. Cox and logistic regressions were used to model the effect on recurrence and positive surgical margins (PSM), respectively. Results and limitations: A total of 481 men had PSM and 467 experienced recurrence during follow-up. Median follow-up for men without recurrence was 6.6 yr. There were no statistically significant differences in recurrence rate between degrees of NS. The PSM rate was significantly higher with a higher degree of NS: interfascial NS, odds ratio (OR) 2.32 (95% confidence interval [CI] 1.69–3.16); intrafascial NS, OR 3.23 (95% CI 2.17–4.80). Recurrence rates were higher for patients with pT2 disease and PSM (hazard ratio [HR] 3.32, 95% CI 2.43–4.53) than for patients with pT3 disease without PSM (HR 2.08, 95% CI 1.66–2.62). The lack of central review of pathological specimens is a limitation. Conclusions: A higher degree of NS significantly increased the risk of PSM but did not significantly increase the risk of cancer recurrence. Combined with the known functional benefits of NS surgery, these results underscore the need to identify an individualised balance. Patient summary: In this report we looked at the effect of a nerve-sparing approach during removal of the prostate on cancer outcomes for patients having robot-assisted surgery at seven Swedish hospitals. We found that a high degree of nerve-sparing increased the rate of cancer positivity at the margins of surgical specimens and that positive surgical margins increased the risk of recurrence of prostate cancer. © 2021 The Authors

- BackgroundIn clinical research information can be retrieved through various sources. The aim is to evaluate the agreement between answers in patient questionnaires and clinical reports in a study of patients after radical prostatectomy and patient characteristics associated with agreement between these two data sources.MethodsIn the prospective non-randomized longitudinal trial LAParoscopic Prostatectomy Robot Open (LAPPRO) 4003 patients undergoing radical prostatectomy at 14 centers in Sweden were followed. Analysis of agreement is made using a variety of methods, including the recently proposed Gwet's AC1, which enables us to handle the limitations of Cohen's Kappa where agreement depends on the underlying prevalence.ResultsThe incidence of postoperative events was consistently reported higher by the patient compared with the clinical reports for all outcomes. Agreement regarding the absence of events (negative agreement) was consistently higher than agreement regarding events (positive agreement) for all outcome variables. Overall impression of agreement depends on which measure used for the assessment. The previously reported desirable properties of Gwet's AC1 as well as the patient characteristics associated with agreement were confirmed.ConclusionThe differences in incidence and agreement across the different variables and time points highlight the importance of carefully assessing which source of information to use in clinical research.

- Objective: To evaluate the effect of intrusive thoughts at diagnosis on quality of life, depressed mood and waking up with anxiety up to two years after radical prostatectomy. Method: The Laparoscopic Prostatectomy Robot Open (LAPPRO) trial was a prospective, longitudinal multicenter study of 4003 patients undergoing radical prostatectomy. Questionnaire data were collected preoperatively, at 3, 12 and 24 months after surgery. Results: The group of patients with intrusive thoughts at diagnosis had a statistically significant higher postoperative prevalence of impaired quality of life, depressed mood and waking up with anxiety as compared with the group of patients with no or minor intrusive thoughts. The highest risk increase for impaired QoL, depressed mood and waking up with anxiety ≥1/week was at 12, 3 and 3 months, respectively, where the three outcomes increased by 38% (RR: 1.38; 95%CI: 1.27–1.49)), 136% (RR: 2.36; 95%CI: 1.74–3.19)) and 165% (RR: 2.65; 95%CI: 2.22–3.17)), respectively. Conclusions: The demonstrated link between intrusive thoughts and quality of life, depressed mood and waking up with anxiety deliver is further evidence to the idea that intrusive thoughts has potential as an endpoint for assessing and predicting psychological distress among men with prostate cancer diagnosis.

- Objective: The aim of this study was to evaluate the association of self-assessed preoperative physical activity, alcohol consumption and smoking with self-assessed quality of life, negative intrusive thoughts and depressed mood after radical prostatectomy.Materials and methods: The Laparoscopic Prostatectomy Robot Open (LAPPRO) trial was a prospective, controlled, non-randomized longitudinal trial of patients (n=4003) undergoing radical prostatectomy at 14 centers in Sweden. Validated patient questionnaires were collected at baseline, and 3, 12 and 24 months after surgery.Results: Preoperative medium or high physical activity or low alcohol consumption or non-smoking was associated with a lower risk of depressed mood. High alcohol consumption was associated with increased risk of negative intrusive thoughts. Postoperatively, quality of life and negative intrusive thoughts improved gradually in all groups. Depressed mood appeared to be relatively unaffected.Conclusions: Evaluation of preoperative physical activity, tobacco and alcohol consumption habits can be used to identify patients with a depressed mood in need of psychological support before and immediately after surgery. Quality of life and intrusive thoughts improved postoperatively.

- Objective Differences in outcome after radical prostatectomy for prostate cancer can partly be explained by intersurgeon differences, where degree of experience is one important aspect. This study aims to define the learning curve of robot-assisted laparoscopic prostatectomy (RALP) regarding oncological and functional outcomes. Materials and methods Out of 4003 enrolled patients in the LAPPRO trial, 3583 met the inclusion criteria, of whom 885 were operated on by an open technique. In total, 2672 patients with clinically localized prostate cancer from seven Swedish centres were operated on by RALP and followed for 8 years (LAPPRO trial). Oncological outcomes were pathology-reported surgical margins and biochemical recurrence at 8 years. Functional outcomes included patient-reported urinary incontinence and erectile dysfunction at 3, 12 and 24 months. Experience was surgeon-reported experience before and during the study. The relationship between surgeon experience and functional outcomes and surgical margin status was analysed by mixed-effects logistic regression. Biochemical recurrence was analysed by Cox regression, with robust standard errors. Results The learning curve for positive surgical margins was relatively flat, with rates of 21% for surgeons who had performed 0-74 cases and 24% for surgeons with > 300 cases. Biochemical recurrence at 4 years was 11% (0-74 cases) and 13% (> 300 cases). Incontinence was stable over the learning curve, but erectile function improved at 2 years, from 38% (0-74 cases) to 53% (> 300 cases). Conclusions Analysis of the learning curve for surgeons performing RALP showed that erectile function improved with increasing number of procedures, which was not the case for oncological outcomes.

- Radical prostatectomy reduces mortality among patients with localized prostate cancer, however up to 35% of patients will experience biochemical recurrence, often treated with salvage radiotherapy. The objective of the study was to investigate long-term effects of salvage radiotherapy.A prospective, controlled, non-randomized trial at 14 Swedish center's including 4,003 patients scheduled for radical prostatectomy 2008-2011. A target trial emulation approach was used to identify eligible patients that was treated with salvage radiotherapy. The control group received no salvage radiotherapy. Outcomes were assessed by patient questionnaires on ordinal scales and statistical group comparisons were made using ordered logit regression with adjustment for baseline outcome and confounding factors. The primary endpoints were bowel, urinary and sexual function and bothering due to dysfunction at 8 years.Eleven percent (330/3,139) of the analyzed study population received salvage radiotherapy. Fecal leakage, leakage of mucus and hematochezia were more common after receiving salvage radiotherapy compared with the control group; 4.5% versus 2.6% odds ratio (95% confidence interval [CI]): (1.90 [1.38; 2.62]), 6.8% versus 1.5% 4.14 (2.98; 5.76) and 8.6% versus 1.2% 4.14 (2.98; 5.76), respectively. Urinary incontinence, erectile dysfunction and hematuria were more common after receiving salvage radiotherapy, 34% versus 23% 2.23 (2.65; 3.00), 65% versus 57% 1.65 (1.18; 2.29) and 16% versus 1.6% 11.17 (5.68; 21.99), respectively.Salvage radiotherapy was associated with increased risk for fecal leakage, hematochezia, urinary incontinence and hematuria. Our results emphasize the importance of selecting patients for salvage radiotherapy to avoid overtreatment and to give high quality pre-treatment information to ensure patients' preparedness for late side-effects.

- BACKGROUND: Many clinicians believe that preparedness before surgery for possible post-surgery side effects reduces the level of bother experienced from urinary incontinence and decreased sexual health after surgery. There are no published studies evaluating this belief. Therefore, we aimed to study the level of preparedness before radical prostatectomy and the level of bother experienced from urinary incontinence and decreased sexual health after surgery. MATERIAL AND METHODS: We prospectively collected data from a non-selected group of men undergoing radical prostatectomy in 14 centers between 2008 and 2011. Before surgery, we asked about preparedness for surgery-induced urinary problems and decreased sexual health. One year after surgery, we asked about bother caused by urinary incontinence and erectile dysfunction. As a measure of the association between preparedness and bothersomeness we modeled odds ratios (ORs) by means of logistic regression. RESULTS: Altogether 1372 men had urinary incontinence one year after surgery as well as had no urinary leakage or a small urinary dribble before surgery. Among these men, low preparedness was associated with bother resulting from urinary incontinence [OR 2.84; 95% confidence interval (CI) 1.59-5.10]. In a separate analysis of 1657 men we found a strong association between preparedness for decreased sexual health and experiencing bother from erectile dysfunction (OR 5.92; 95% CI 3.32-10.55). CONCLUSION: In this large-sized prospective trial, we found that preparedness before surgery for urinary problems or sexual side effects decreases bother from urinary incontinence and erectile dysfunction one year after surgery.

- Little is known concerning what may influence surgeon satisfaction with a surgical procedure and its associations with intraoperative factors. The objective was to explore the relationships between surgeons' self-assessed satisfaction with performed radical prostatectomies and intraoperative factors such as technical difficulties and intraoperative complications as reported by the surgeon subsequent to the operation.We utilized prospectively collected data from the controlled LAPPRO trial where 4003 patients with prostate cancer underwent open (ORP) or robot-assisted laparoscopic (RALP) radical prostatectomy. Patients were included from fourteen centers in Sweden during 2008-2011. Surgeon satisfaction was assessed by questionnaires at the end of each operation. Intraoperative factors included time for the surgical procedure as well as difficulties and complications in various steps of the operation. To model surgeon satisfaction, a mixed effect logistic regression was used. Results were presented as odds ratios (OR) with 95% confidence intervals (CI).The surgeons were satisfied in 2905 (81%) and dissatisfied in 702 (19%) of the surgical procedures. Surgeon satisfaction was not statistically associated with type of surgical technique (ORP vs. RALP) (OR 1.36, CI 0.76; 2.43). Intraoperative factors such as technical difficulties or complications, for example, suturing of the anastomosis was negatively associated with surgeon satisfaction (OR 0.24, CI 0.19; 0.30).Our data indicate that technical difficulties and/or intraoperative complications were associated with a surgeon's level of satisfaction with an operation.
