Objective: To appraise the outcomes on the Retzius-sparing robot-assisted radical prostatectomy (Rs-RARP) learning curve of a surgeon with previous experience of anterior (standard) RARP. Materials and methods: The first 50 cases during the Rs-RARP learning curve (group 1) and 50 cases after the second 100 cases with the standard approach (group 2) were comprised in the study. Patients who used zero or one safety pads were considered continent. Erectile function recuperation was characterized as the competence to achieve penetrative intercourse without receiving any medication. All patients were reevaluated at two weeks, first, third, sixth, and 12th months after surgery using IIEF-5, PSA level, and continence status. Results: Immediate continence rates following catheter removal were 32/50 (64%) in Rs-RARP group and 26/50 (52%) in S-RARP group (p = 0.224). The continence recovery rate was 48/50 (96%) in Rs-RARP group and 46/50 (92%) in the S-RARP group at 12 months follow-up (p = 0.400). Total nerve-sparing surgery was enforced in 36/50 (72%) patients for group 1 and 35/50 (70%) patients for group 2. Potency recovery was 27/43 (62.8%) in Rs-RARP and 30/44 (68.2%) for S-RARP at 12 months follow up (p = 0.597). Surgical margin positivity was detected in 6/50 (12%) cases in the Rs-RARP group and in 4/50 (8%) cases in the S-RARP (p = 0.444). Conclusions: Functional and oncological results are not negatively affected in the first 50 cases for a surgeon who is experienced in S-RARP before transition to the Rs-RARP method.

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.

Introduction: Since its introduction, robot-assisted laparoscopic radical prostatectomy (RARP) has gained widespread popularity, but is associated with a variable learning curve. Herein, we report the positive surgical margin (PSM) rates during the RARP learning curve of a single surgeon with significant previous laparoscopic radical prostatectomy (LRP) experience.Methods: We performed a prospective cohort study of the first 400 men with prostate cancer treated with RARP by a single surgeon (BS) with significant LRP experience. Our primary outcome was the impact of case timing in the learning curve on margin status. Our analysis was conducted by dividing the case numbers into quartiles (Q1‒Q4) and determining if a case falling into an earlier quartile had an impact on margin status relative to the most recent quartile (Q4).Results: The Q1 cases had an odds ratio for margin positivity of 1.74 compared to Q4 (p=0.1). Multivariate logistic regression did not demonstrate case number to be a significant predictor of PSM. The mean Q1 operative time was 207.4 minutes, decreasing to 179.2 by Q4 (p<0.0001). The mean Q1 estimated blood loss was 255.1 ml, decreasing to 213.6 by Q4 (p=0.0064). There was no change in length of hospitalization within the study period.Conclusions: Even when controlling for copredictors, a statistically significant learning curve for PSM rate of a surgeon with significant previous LRP experience was not detected during the first 400 RARP cases. We hypothesize that previous LRP experience may reduce the RARP PSM learning curve.

The study objective is to study the role of multiparametric magnetic resonance imaging (mpMRI), to predict extracapsular extension, infiltration of the seminal vesicles, neurovascular bundles and status of positive surgical margin (PSM) in robot-assisted radical prostatectomy (RARP) with fascio- and nerve-sparing and anatomy-sparing techniques in patients with low and intermediate oncological risk; to evaluate safety of RARP with anatomy-sparing techniques in the context of oncological results in the studied patient cohort.Materials and methods. Fifty-four males underwent mpMRI in the device with magnetic field density 3 Tesla without endorectal coil. Results of mpMRI were analyzed using PI-RADS v.2. Prostate-specific antigen level, results of prostate biopsy, nomogram were analyzed. All patients were included into groups with low and intermediate oncological risk. The patients underwent RARP with anatomy-sparing techniques. Gross specimen removed during the surgery was stained with tissue stain DECOLA and subjected to stepwise pathomorphological analysis. Comparative analysis of tumor lesion localization was performed for mpMRI and pathomorphological examination. The study concentrated on the largest tumor lesion locations. The anterior surface of the prostate was examined in detail. Patients were classified per risk groups in accordance with the National Comprehensive Cancer Network (NCCN) and D'Amico criteria.Results. Full or partial overlap of the lesions per mpMRI and pathomorphological examination were observed in 48 (88.9 %) patients; locations of tumor lesions disagreed in 6 (11.1 %) patients. PSM was detected in 8 (14.8 %) patients; among them in 7 (12.9 %) the size was between 0.1 and 0.4 cm. On the anterior surface of the prostate 3 (5.5 %) PSM were observed, 2 of which were between 0.14 and 0.4 cm, 1 was multifocal, larger than 0.3 cm. Per mpMRI results and histological examination, the anterior surface (fibromuscular stroma) was affected in 14 (25.9 %) and 11 (20.4 %) cases, respectively. Among them, lesion locations overlapped in 11 observations. Results of anatomy-sparing RARP show increased PSM rate compared to traditional nerve-sparing based on the anterior surface of the prostate.Conclusion. Routine mpMRI for patients who are planned to undergo RARP allows to justify selection of anatomy-sparing RARP or rejection of modification in favor of more thorough dissection. mpMRI plays a significant role on planning of anatomy-sparing RARP, achievement of negative surgical margin in patients with low and intermediate risk of oncological progression. Evaluation of the location and size of cancer lesion in the prostate allows to plan for special aspects of anatomy- and/or nerve-sparing techniques, achieve lower PSM rate, optimize oncological and functional surgical results in localized prostate cancer.

Objectives To assess whether the timing of post-operative Phosphodiesterase Inhibitor (PDE5i) therapy after Robot Assisted Radical Prostatectomy (RARP) is associated with a change in early erectile function outcomes. Additionally, to determine whether there are differences in continence or safety outcomes. Subjects/patients and methods Data was prospectively collected from a single surgeon in one tertiary centre and retrospectively evaluated. 158 patients were treated with PDE5i therapy post RARP over a two-year period. PDE5i therapy was started: immediately (day 1-2) post-op in 29%, early (day 3-14) post-op in 37% and late (after day 14) post-op in 34%. EPIC-26 Erectile Function (EF) scores were collected pre-op and post-op with a median follow-up time of 43 days. Results The median age was 64 and the median BMI was 27. 9% of the series had Charlson Co-Morbidities. There were no significant differences in pre-operative characteristics between the therapy groups. Patients that had bilateral nerve sparing had a mean drop in Erectile Function (EF) score by 5.4 compared to 8.8 in the unilateral group. Additionally, 34.9% of bilateral nerve sparing patients returned to baseline compared to 12.1% of unilateral. Drop in EF scores and percentage return to baseline for unilateral nerve sparing was respectively 9 and 11.1% of immediate therapy, 7 and 14.8% of early therapy and 9.7 and 9.5% of late therapy (p=0.9 and p=0.6). For bilateral nerve sparing this was respectively 3.5 and 42.9% immediate therapy, 5.5 and 35.5% early therapy and 7.3 and 25% late therapy (p=0.017 and p=0.045). Pad free and social continence was achieved in 54% and 37% of those receiving immediate therapy, 60% and 33% for early therapy and 26% and 54% for late therapy. There were no differences in compliance, complication or readmission outcomes. Conclusion In patients with bilateral nerve sparing RARP, immediate post-operative PDE5i therapy may protect EF. Early onset (3-14 days) may also provide a benefit compared to initiating PDE5i therapy later (after 14 days). Expediting therapy for patients undergoing unilateral nerve sparing may also provide a benefit; however, the differences are less pronounced. Immediate or early PDE5i therapy also improved early continence outcomes for patients with bilateral nerve sparing, compared to late therapy. There were no differences in compliance, complication or readmission rates between the groups. Therefore, immediate PDE5i therapy should be considered in patients following nerve sparing RARP in order to maximise functional outcomes, especially in those undergoing bilateral nerve spare.

Abstract Background Nonoperative management after neoadjuvant treatment in low rectal cancer enables organ preservation and avoids surgical morbidity. Our aim is to compare oncological outcomes in patients with clinical complete response in watch and wait strategy with those who received neoadjuvant therapy followed by surgery with a pathological complete response. Methods Patients with non-metastatic rectal cancer after neoadjuvant treatment with clinical complete response in watch and wait approach (group 1, n = 26) and complete pathological responders (ypT0N0) after chemoradiotherapy and surgery (group 2, n = 22), between January 2011 and October 2018, were included retrospectively, and all of them evaluated and followed in a multidisciplinary team. A comparative analysis of local and distant recurrence rates and disease-free and overall survival between both groups was carried out. Statistical analysis was performed using log-rank test, Cox proportional hazards regression model, and Kaplan-Meier curves. Results No differences were found between patient’s demographic characteristics in both groups. Group 1: distance from the anal verge mean 5 cm (r = 1–12), 10 (38%) stage III, and 7 (27%) circumferential resection margin involved. The median follow-up of 47 months (r = 6, a 108). Group 2: distance from the anal verge mean 7 cm (r = 2–12), 16 (72%) stage III, and 13 (59%) circumferential resection margin involved. The median follow-up 49.5 months (r = 3, a 112). Local recurrence: 2 patients in group 1 (8.3%) and 1 in group 2 (4.8%) (p = 0.6235). Distant recurrence: 1 patient in group 1 (3.8%) and 3 in group 2 (19.2%) (p = 0.2237). Disease-free survival: 87.9% in group 1, 80% in group 2 (p = 0.7546). Overall survival: 86% in group 1 and 85% in group 2 (p = 0.5367). Conclusion Oncological results in operated patients with pathological complete response were similar to those in patients under a watch and wait strategy mediating a systematic and personalized evaluation. Surgery can safely be deferred in clinical complete responders.

Abstract Background To assess the learning curve in laparoscopic radical prostatectomy (LRP) performed by a single surgeon who had a healthcare career as a surgical first assistant for 2 years in high-volume centers treating > 150 cases per year. Methods The records of 80 LRP cases performed between October 2017 and August 2018 by a single surgeon were consecutively divided into four groups (groups A = first 20 cases, B = second 20 cases, C = third 20 cases, and D = last 20 cases). The groups were compared in terms of surgical and functional outcomes with a minimum follow-up of 6 months. Results Clinical and surgical stages of the four groups were similar between groups. The operative time (126.8 ± 5.48 min; P = 0.001) and time of removal of the drain (1.65 ± 0.93 days; P = 0.029) were significantly lower in group D; however, hospitalization, catheterization time, and blood loss were similar between groups. The complication rate was low. No patient had a visceral injury, and there were no procedures needed to open conversion. The positive surgical margin (PSM) rates were similar between groups. In terms of continence and potency, all groups were similar at the 6th-month follow-up after surgery. Conclusions Our results showed that prior experience in laparoscopic surgery as a surgical first assistant in a high-volume center improves the learning curve and oncological and functional outcomes, and helps to minimize the complication rate

Abstract Introduction To assess whether the timing of post-RARP PDE5i therapy affects early erectile function, continence, or safety outcomes. Method Data from 158 patients treated with PDE5is post-RARP was prospectively collected over two years from a single surgeon at one tertiary centre and retrospectively evaluated. Therapy was started: immediately (day 1-2) in 29%, early (day 3-14) in 37% and late (after day 14) post-op in 34%. EPIC-26 Erectile Function (EF) scores were collected pre-op and post-op after a median 43-day follow-up interval. Results Drop in EF scores and percentage return to baseline post unilateral nerve sparing (UNS) compared to bilateral nerve sparing (BNS) RARP was respectively 9 and 11.1% versus 3.5 and 42.9% of immediate therapy, 7 and 14.8% versus 5.5 and 35.5% of early and 9.7 and 9.5% versus 7.3 and 25% of late. Pad free and social continence was achieved in 54% and 37% of those receiving immediate therapy, 60% and 33% for early and 26% and 54% for late. Conclusions Immediate post RARP PDE5i therapy may protect EF and should be considered clinically, with more benefits for BNS than UNS patients. Immediate or early, rather than late, PDE5i therapy improved early continence in BNS patients.

Background and aims. To assess the outcomes of robotic radical prostatectomy in two different age subgroups of pre-operatively potent patients: younger than 50 years and older than 65 years.Methods. We included in the present study a number of 202 patients with prostate cancer divided into two groups: 99 patients older than 65 years (group 1) and 103 patients younger than 50 years (group 2).Results. More than half of the younger patients were low-risk vs 57% of the older patients who were high-risk. Overall positive surgical margins rate was 21.2% in group 1 vs 12.1% in group 2. The early biochemical recurrence at 6 months after radical prostatectomy was 4% in group 1 vs 11.6% in group 2. The continence rate at 6 months was similar between the two groups and was not correlated with the patients’ age (p=0.72), nerve-sparing (p=0.3 for group 1, p=0.92 for group 2) or pathological staging (overall p=0.81, p=0.89 in group 1 and p=0.63 in group 2). We observed a significantly higher rate of potency for patients in group 2 (91.5% vs 47.2%, p<0.0001). The most important factor associated with the regain of potency at 6 months after the procedure was the age of the patient (p<0.0001), independently of the type of nerve-sparing performed.Conclusions. Age seems to be the most important predictor of the regain of potency after robotic radical prostatectomy. Patients should be counseled accordingly in order to have realistic expectations about the functional results after robotic-assisted surgery.
