BACKGROUND Although many studies address the learning curve for robot-assisted laparoscopic prostatectomy (RALP), little is known concerning the results for pelvic lymph node dissection (LND) during RALP. PATIENTS AND METHODS Between 2006 and 2011, two surgeons performed 904 RALP procedures. LND was performed in 440 (48.6%) cases based on the European Association of Urology guidelines. Both surgeons had extensive experience with open LND for both prostate and bladder cancer. Clinical data were prospectively recorded into an online database. Complications were reported using the Clavien-Dindo system and documented prospectively. RESULTS For both surgeons, the operative time for LND decreased over time during the first 150 LND procedures. After that, a mean plateau of operative time of 49 minutes for LND was reached. Nodal yield increased from a mean of 10 nodes for the first 50 cases to 14 for cases 351 to 400. The percentage of positive nodes increased significantly in these intervals from 4% to 23.1% (P<0.001, Mann Whitney U test). Overall complications by grade were not significantly different between RALP with or without LND. In 440 LND cases, 5 (1.5%) grade IIIb complications occurred. All were infection related with bowel perforation in one. Symptomatic lymphoceles necessitating drainage were present in five (1.5%) men. Thromboembolic events (0% vs 1.5%) and anastomosis dehiscence (0.2% vs 1.1%) were more common in men with LND. During the learning curve, the incidence of Clavien grade I and II but not grade III and IV complications decreased. CONCLUSION An improvement pattern for LND during RALP is observed for operative time, nodal yield node positivity rate, and complication rate during the first 400 cases of LND.

BACKGROUND AND PURPOSE Considering the anatomic proximity of the internal iliac lymph nodes and the pelvic plexus, it may be expected that more extensive pelvic nodal dissection is associated with an increased risk of damage to the small pelvis neural and vascular structures. We evaluate whether nodal dissection is associated with functional outcome after robot-assisted radical prostatectomy (RARP). PATIENTS AND METHODS In a series of 798 RARP procedures, 325 (40.7%) patients underwent a lymph node dissection. Continence, sexual function, and lower urinary tract symptoms (LUTS) were assessed using the International Consultation of Incontinence Questionnaire short form (ICIQ)-SF), International Index of Erectile Function-15, and European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC-QLQ)-PR25 questionnaires before and at 6 months intervals after RARP. RESULTS Preoperative ICIQ-SF, IIEF-15, and PR25-LUTS scores were similar for men with and without nodal dissection. Normal postoperative erectile function (IIEF-EF >24) at 6 months was reported by 1.7%, 9.1%, and 50.4% of men with no, unilateral, and bilateral nerve preservation and normal preoperative erectile function. All domains of the IIEF-15 score showed a negative correlation with the number of removed lymph nodes. In 70 of 325 (21%) cases with nodal dissection, more than 10 nodes were removed. Men with more than 10 nodes removed had lower IIEF-15 domain scores compared with men with 1 to 10 removed lymph nodes. The postoperative ICIQ-SF and PR25-LUTS scores were not associated with extent of nodal dissection. Nodal metastases were found in 5.9% and 15.7% of men with ≤ 10 nodes and >10 nodes removed (P=0.005). In a multivariate analysis, extent of fascia preservation (FP-score), preoperative IIEF-EF, and number of removed nodes were the strongest independent predictors of postoperative erectile function recovery. CONCLUSION More extensive nodal dissection was associated with impaired postoperative sexual function recovery but not continence and voiding function after RARP, independent of preoperative function and nerve preservation.

INTRODUCTION Functional outcome and quality of life (QOL) domains are important outcomes after curative therapy for prostate cancer. Although useful for scientific purposes, QOL questionnaires may be too extensive for daily routine, and single questions or interview-assessed outcomes may be more practical alternatives. The QOL outcomes of these measures were compared. MATERIALS AND METHODS The QOL of patients undergoing Robot-Assisted Radical Prostatectomy (RARP) in our hospital was monitored before and after treatment using both brief standardized interview questions, as well as more extensive validated questionnaires. The interview questions address erectile function and urinary continence with only one question on each subject (both four response items). Questionnaires included a total of 74 questions (EORTC-QLQ-C30, EORTC-QLQ-PR25, international index of erectile function-15, and international consultation on incontinence questionnaire-short form). RESULTS In 925 RARP patients, pre- and postoperative interview and questionnaire QOL data were available with a median follow up of 20 months. Improvement in both erectile function and continence scores occurred up till 2 years after the RARP for both interview- and questionnaire-based evaluations. On an individual patient basis, interview scores poorly correlated with questionnaire-based domains for continence and erectile function. Single questions from the questionnaire showed better correlation with domain scores. Functional recovery of continence after 1 year was worse when assessed by questionnaire than by interview evaluation. A decrease in physical (8%) and overall QOL (12%) after prostatectomy as assessed by the EORTC-QLQ-C30 questionnaire was better predicted by questionnaire-based than interview-based scores. Continence scores had a greater impact on physical and overall QOL scores than on erectile function scores. CONCLUSION Interview/assessed continence and erectile function outcome after RARP showed limited association with questionnaire-based evaluation and may overestimate functional recovery. Continence scores for both interviews and questionnaires were stronger correlated with physical and overall QOL than erectile function scores.

Abstract Objective.The aim of this study was to determine whether deferred radical therapy for low-risk prostate cancer has an additionally unfavourable effect on quality of life (QoL). Substantial numbers of patients on active surveillance (AS) are eventually treated. Material and methods. Prostate cancer patients treated with robot-assisted radical prostatectomy (RARP) in the NCI-AvL (Amsterdam, The Netherlands) received systematic QoL questionnaires preoperatively and postoperatively. Questionnaires included the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core Module and Prostate Module (EORTC-QLQ-C30 and EORTC-QLQ-PR25), International Index of Erectile Function-15 (IIEF-15) and International Consultation on Incontinence Questionnaire Short Form (ICIQ-SF). Patients with low-risk prostate cancer who received RARP after an initial period of AS (AS-RARP group) were compared with similar patients who primarily elected surgery (direct-RARP group). Results.The AS-RARP group included 29 patients who received RARP after a median period of 15.4 months of AS (range 3.0–18.8 months). Main reasons for deferred radical therapy were repeat biopsy risk reclassification (45%) and prostate-specific antigen progression (38%). The direct-RARP group included 363 patients treated after 3.3 months (range 0.1–45.5 months). RARP generally resulted in clinically relevant unfavourable changes on different QoL domains in both groups. Preoperatively the AS-RARP group showed more favourable scores on multiple QoL domains (physical functioning, p = 0.004; role functioning, p = 0.001; global health, p = 0.043; sexual activity, p = 0.001; sexual functioning, p = 0.029; IIEF-15, p = 0.042). Postoperatively, most of these more favourable scores in the AS-RARP group had changed to scores similar to the direct-RARP group, except for IIEF-15 (p = 0.027) and urinary symptoms (p = 0.001). When using a 12 month treatment delay threshold, a similar but less distinct effect was seen. Conclusions.Patients with low-risk prostate cancer who choose AS have more favourable preoperative QoL scores than patients who primarily elect radical prostatectomy, but these groups show similar postoperative QoL scores.

OBJECTIVE To investigate the association between benign prostatic hyperplasia (BPH) patterns, classified by magnetic resonance imaging (MRI), with lower urinary tract symptoms (LUTS) or continence, preoperatively and after robot-assisted laparoscopic radical prostatectomy (RARP). MATERIALS AND METHODS This retrospective study included 49 prostate cancer patients, with prostate size >47 cm3, who underwent an endorectal MRI followed by RARP. Five BPH patterns were identified according to Wasserman, and additional prostate measurements were recorded. LUTS were assessed using the International Prostate Symptom Score and the PR25-LUTS-Questionnaire score. Continence was assessed using the International Consultation of Incontinence Questionnaire-Short Form. RESULTS BPH pattern 3 (44.9%) was identified most common, followed by pattern 5 (26.6%), 1 (24.5%), and 2 and 4 (both 2%). BPH patterns were significant predictors of preoperative LUTS, with pedunculated with bilateral transition zone (TZ) and retrourethral enlargement (pattern 5) causing more severe symptoms compared with bilateral TZ and retrourethral enlargement (pattern 3) and bilateral TZ enlargement (pattern 1), whereas pattern 3 was additionally associated with more voiding symptoms compared with pattern 1. None of the BPH patterns was predictive of postoperative LUTS and continence. Independent predictors of continence at 12 months were lower preoperative PR25-LUTS score (P = .022) and longer membranous urethral length (P = .025). CONCLUSION MRI is useful for classifying patients in BPH patterns which are strongly associated with preoperative LUTS. However, BPH patterns did not predict remnant LUTS or postoperative incontinence. Postoperative continence status was only associated with preoperative LUTS and membranous urethra length.

OBJECTIVE The purpose of this study was to identify factors associated with mental health (MH) problems in prostate cancer (PC) survivors. Toward this end, we evaluated (1) differences in the prevalence of MH problems between PC survivors and age-matched men from the general population (GenPop) and (2) correlates of MH in PC survivors and the GenPop. METHODS AND MATERIALS In this observational case-control study, we age-matched PC survivors (n = 644, alive≥5y after diagnosis of a stage I-IV carcinoma) recruited from Dutch community hospitals (Patient Reported Outcomes Following Initial treatment and Long-term Evaluation of Survivorship registry) with GenPop peers (n = 644) selected from a population-based sample recruited in general practices (NIVEL). MH was operationalized using the 5-item Mental Health Inventory of the Short Form Health Survey (SF-36). Potential correlates of MH included sociodemographic characteristics, health-related quality of life scores, and clinical characteristics (PC survivors only). We used analysis of (co)variance and chi-square tests to address the 2 research questions. RESULTS We observed clinically relevant MH symptoms in 14% of the PC survivors and 6% of the GenPop controls (P<0.01, odds ratio = 2.45 [1.66-3.62]). The most important correlates of lower MH scores in the PC survivors were being widowed, a lower educational level, lower general health perceptions, more bodily pain and urinary bother, and less sexual satisfaction. The most important correlates of lower MH scores in the GenPop were as follows: lower general health perceptions, more role limitations because of physical problems, and more bodily pain. CONCLUSIONS Our results indicate that long-term PC survivors have poorer MH, as assessed by the 5-item Mental Health Inventory questionnaire, than men of a comparable age from the GenPop without a history of PC. Attention to potentially modifiable factors associated with MH problems in PC survivors, such as urinary function and its related bother, bodily pain, and sexual satisfaction, may help to prevent or limit MH problems in this survivor population.

Purpose: The aims of this study were to 1) describe preferred and experienced roles in treatment decision making among patients with localized prostate cancer, 2) identify how often the roles experienced by patients matched their preferred roles and 3) determine whether active involvement in decision making regardless of role preferences or concordance between preferred and experienced roles would be the strongest predictor of more favorable patient reported outcomes. Materials and Methods: In this prospective, multicenter, observational study we obtained serial questionnaire data from 454 patients with newly diagnosed, localized prostate cancer (cT1‐cT2, or Gleason 7 or less and prostate specific antigen 20 ng/ml or less). Questionnaires were completed prior to treatment and at the 3, 6 and 12‐month posttreatment followups. Clinical data were obtained from the patient medical records. Active involvement and role concordance were operationalized using the CPS (Control Preferences Scale). ANOVA and effect sizes (small and medium Cohen d = 0.2 and 0.5, respectively) were used to compare patient knowledge of prostate cancer, decision conflict, decision regret and overall health related quality of life. Results: Of the patients 393 (87%) reported having been actively involved in treatment decision making. However, 78 patients (17%) indicated having had less or more involvement than preferred. Active involvement was significantly associated with more prostate cancer knowledge (d = 0.30), less decision conflict (d = 0.52) and less decision regret (d = 0.34). Role concordance was also but less strongly associated with less decision conflict (d = 0.41). Conclusions: Our findings support a policy of encouraging all patients with localized prostate cancer regardless of their stated role preferences to be actively involved in the treatment decision.
