Abstract
Robot-assisted radical prostatectomy has become the standard of care for the removal of localized prostate cancer. Positive outcomes depend upon the precise removal of the prostate and associated tissue without damage to nearby structures. This process can be aided by fluorescence-guided surgery to enhance the visual contrast between different structures. Here the authors have conducted a systematic review using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines to identify ten investigations into the use of fluorescence-guided surgery in robot-assisted radical prostatectomy. These studies used fluorescent tracers to identify structures, including the prostate, neurovascular bundle and lymph nodes. These studies demonstrate the safe and effective use of fluorescence-guided surgery in robot-assisted radical prostatectomy and pave the way for further developments in this field.

Abstract
INTRODUCTION Lymphoceles are sometimes formed after pelvic lymph node dissection. However, recurrence at lymphoceles has not been reported previously. Here, we report a case of rapid prognosis of the recurrence at a lymphocele after nephroureterectomy. CASE PRESENTATION A 78-year-old man underwent retroperitoneoscopic radical nephroureterectomy with pelvic lymphadenectomy for left ureteral urothelial carcinoma. The histopathological diagnosis was high-grade invasive urothelial carcinoma with squamous differentiation. Follow-up computed tomography at 3 months postoperatively showed a lymphocele with a small solid component, in the left pelvic region. At 7 months postoperatively, he presented with severe fatigue, and computed tomography showed a solid tumor had replaced the lymphocele. Computed tomography-guided biopsy was performed and histopathological diagnosis was squamous cell carcinoma. CONCLUSION This report provides support for possible recurrence at the lymphocele after nephroureterectomy. If lymphocele occurs after surgery for malignant disease, it is recommended to follow up with the possibility of recurrence in the lymphatic cysts in mind.

Urol Int 2021; 106:28-34. [PMID: 33567440 DOI: 10.1159/000512960] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2020] [Accepted: 11/04/2020] [Indexed: 11/19/2022]
Abstract
BACKGROUND Robot-assisted radical prostatectomy (RARP) including pelvic lymph node dissection (PLND) is the current state of the art in surgical therapy of localized prostate cancer with intermediate or high risk. PLND in particular is associated with morbidity inherent to this method; the rate of symptomatic lymphoceles (sLCs), for example, ranges up to 10%. OBJECTIVE Various intraoperative modifications have been developed with the aim of reducing the sLC rate. Based on current studies, a peritoneal interposition flap (PIF) appears to be one of the most effective methods for this purpose. Under the criteria of a systematic review, 5 retrospective studies have been identified until now, 4 of which showed a positive effect of PIF on the sLC rate. RESULTS AND LIMITATIONS A total of 1,308 patients were included in the aggregated analysis of these 5 studies. The amount of sLCs was 1.3% (8/604) and 5.7% (40/704) in the PIF and standard groups, respectively (p < 0.001). The resulting odds ratio (OR) was 0.23 (95% confidence interval [CI]: 0.05-0.99), taking in-to account a noteworthy heterogeneity of the 5 studies (Q = 9.47, p = 0.05; I2 = 58%). In addition, a prospective randomized and blinded study (Pianoforte trial) with corresponding sLC rates of 8.3% (9/108) versus 9.7% (12/124) (p = 0.820) exists. In this study, the OR was 0.85 (95% CI: 0.34-2.10, p = 0.722). CONCLUSION Despite positive results from retrospective studies with indirect evidence, the role of the PIF in the reduction of sLC in RARP could not be conclusively assessed yet. The results of the first prospective randomized study do not show a positive effect of PIF, declaring a research gap for further studies with direct evidence.

Abstract
INTRODUCTION Pelvic lymphocele is the most common complication of pelvic lymph node dissection after radical prostatectomy. Management of symptomatic pelvic lymphocele begins with percutaneous drainage, followed by sclerotherapy or surgical marsupialization and more recently, lymphatic embolization. In this article, we show the feasibility and results of two lymphatic embolization after prostatectomy with lymph node dissection. CASE PRESENTATION We decided to perform lymphatic embolization in two patients with persistent symptomatic pelvic lymphocele, after percutaneous drainage. This was done through inguinal lymph node puncture using Lipiodol and N-butyl cyanoacrylate glue injection. Drainage removal was done on the day after the procedure and clinical recovery was maintained at follow-up visits, 3 and 4 months later, in both patients. Computed tomography at 6 and 10 weeks after embolization showed the disappearance of the lymphocele. CONCLUSION Our two case reports support the promising results of lymphatic embolization in this pathology.

Abstract
Pelvic lymph node dissection (PLND) is an important component in the staging and prognostication of prostate cancer. We performed a narrative review to assess the literature surrounding PLND: (I) the current guideline recommendations and contemporary utilization, (II) the calculation of patient-specific risk to perform PLND using available nomograms, (III) to review the extent of dissection, and its associated outcomes and complications. Due to the improved lymph node yield, better staging, and theoretical improvement in the control of micro-metastatic disease, guidelines have supported the use of (extended-) PLND in patients deemed to be at intermediate or high risk of lymph node involvement (often at a threshold of 5% on modern risk nomograms). However, in practice, real-world utilization of PLND varies considerably due to multiple reasons. Conflicting evidence persists with no clear oncological benefit to PLND, and a small, but important, risk of morbidity. Complications are rare, but include lymphoceles; thromboembolic events; and more rarely, obturator nerve, vascular, and ureteric injury. Furthermore, changing disease incidence and stage migration in the context of earlier detection overall have led to a decreased risk of nodal disease. The trade-offs between the benefits, harms, and risk tolerance/threshold must be carefully considered between each patient and their clinician.

Abstract
CONTEXT Pelvic lymph node dissection (PLND) in localized prostate cancer is feasible through an open, laparoscopic or robot-assisted approach. Data comparing the three approaches is sparse. OBJECTIVE To perform a review in order to compare the effectiveness of the different PLND approaches. ACQUISITION OF EVIDENCE A search was performed including the following words: ("pelvic lymph node dissection") OR ("pelvic lymphadenectomy") AND ("French"[Language] OR "English"[Language]) AND ("1990"[Date-Publication]: "3000"[Date-Publication]) AND prostatectomy[Title]). Twenty-nine articles were finally included in the qualitative synthesis. EVIDENCE SYNTHESIS Laparoscopic pelvic lymph node dissection in prostate cancer is a minimally invasive procedure with a relatively short operative time, minimal blood loss, lower level of pain, shorter hospital stay, and fewer perioperative complications when compared to an open approach. This technique is more cost-effective than a robot-assisted approach. CONCLUSION Concerning the treatment of localized prostate cancer, laparoscopic pelvic lymph node dissection should be learned and applied by urologists.

Abstract
A common practice during robot-assisted radical prostatectomy (RARP) is to dissect the anterior prostate space and send this anterior fat sample for histological analysis to assess for the presence of any malignant tissue. Theoretically, this may help with prognostication and oncological control, however, is this a futile process? To determine the incidence of malignant tissue found in the anterior prostate (APF) samples sent for histological review. All RARP patients within a single urology centre over a 2-year period were included. The pathology results of these patients were reviewed and the proportion of patients with APF sent were analysed for presence of lymph nodes and malignant tissue. 657 patients were identified. 358 patients had APF samples reviewed by the histopathologists. 38 (10.6%) samples had lymph nodes identified within the sample. Malignant lymph node tissue was found in one patient (0.3%). Given the yield of malignancy found in APF samples is so small and the financial and time burden on pathology services, this process is not worthwhile.

Abstract
Purpose To identify the relevant factors, and create and validate a predictive scoring system for the duration of laparoscopic radical prostatectomy (LRP). Patients and Methods We retrospectively analyzed clinicopathological data from 436 patients who underwent LRP between January 2014 and January 2019, of whom 304 cases were used as a model creation group and 132 were used as a validation group. Uni/multivariate linear regression analysis was performed to determine the predictors of the duration of the procedure and a novel scoring system was created using these predictors. External validation of the scoring system was performed. The Hosmer–Lemeshow test was used to determine the goodness-of-fit of the model and calibration plots were created for visual assessment. Results “Prolonged duration” was defined as a duration of the procedure that was longer than the mean (>150 min) duration. Multivariate analysis showed that body mass index (BMI), prostate volume, intravesicular protrusion of the prostate (IPP), the ratio of the cross-sectional areas of the prostate and the Retzius space (P/R), pelvic lymph node dissection, and neurovascular bundle (NVB) preservation were significant predictors of prolonged duration. A scoring system that included these six parameters was created and the area under the curve achieved during receiver operating characteristic analysis using this scoring system was 0.874 (95% confidence interval [CI]: 0.836–0.913). The Hosmer–Lemeshow test showed that the scoring system was well calibrated (X2=5.339, P=0.376). The external validation showed that the model had high predictive accuracy (AUC=0.835, 95% CI: 0.764–0.906) and goodness-of-fit (X2=4.401, P=0.493). Conclusion The following factors were significantly associated with prolonged duration of laparoscopic radical prostatectomy: BMI, prostate volume, IPP, P/R, pelvic lymph node dissection, and NVB preservation. The novel scoring system created can be used to accurately predict the duration of the procedure, assess the difficulty of surgery, and improve perioperative efficiency.

Abstract
OBJECTIVES To externally validate the currently available nomograms for predicting lymph node invasion (LNI) in patients with prostate cancer (PCa) and to assess the potential risk of complications of extended pelvic lymph node dissection (ePLND) when using the recommended threshold. METHODS A total of 14 921 patients, who underwent radical prostatectomy with ePLND at eight European tertiary referral centres, were retrospectively identified. After exclusion of patients with incomplete biopsy or pathological data, 12 009 were included. Of these, 609 had undergone multiparametic magnetic resonance imaging-targeted biopsies. Among ePLND-related complications we included lymphocele, lymphoedema, haemorrhage, infection and sepsis. The performances of the Memorial Sloan Kettering Cancer Centre (MSKCC), Briganti 2012, Briganti 2017, Briganti 2019, Partin 2016 and Yale models were evaluated using receiver-operating characteristic curve analysis (area under the curve [AUC]), calibration plots, and decision-curve analysis. RESULTS Overall, 1158 patients (9.6%) had LNI, with a mean of 17.7 and 3.2 resected and positive nodes, respectively. No significant differences in AUCs were observed between the MSKCC (0.79), Briganti 2012 (0.79), Partin 2016 (0.78), Yale (0.80), Briganti 2017 (0.81) and Briganti 2019 (0.76) models. A direct comparison of older models showed that better discrimination was achieved with the MSKCC and Briganti 2012 nomograms. A tendency for underestimation was seen for all the older models, whereas the Briganti 2017 and 2019 nomograms tended to overestimate LNI risk. Decision-curve analysis showed a net benefit for all models, with a lower net benefit for the Partin 2016 and Briganti 2019 models. ePLND-related complications were experienced by 1027 patients (8.9%), and 12.6% of patients with pN1 disease. CONCLUSIONS The currently available nomograms have similar performances and limitations in the prediction of LNI. Miscalibration was present, however, for all nomograms showing a net benefit. In patients with only systematic biopsy, the MSKCC and Briganti 2012 nomograms were superior in the prediction of LNI.

Abstract
BACKGROUND Lymphocele is the most common complication arising after pelvic lymph node dissection (PLND) in the setting of robot-assisted radical prostatectomy (RARP). The only data available until now on the utility of a peritoneal flap to prevent lymphocele were retrospectively acquired. METHODS A randomized, controlled, multi-center trial with blinded assessment of endpoints was carried out on 232 patients with prostate cancer who underwent RARP with PLND. The patients in the intervention group were given a peritoneal flap; in the control group, surgery was performed without this modification. The two joint primary endpoints were the rates of symptomatic lymphocele during the same hospitalization as the operative procedure (iT1) and within 90 days of surgery (iT2). The secondary endpoints were lymphocele volume, the need for treatment of lymphocele, complications requiring an intervention, and the degree of postoperative stress incontinence. German Clinical Trials Register number: DRKS00011115. RESULTS The data were evaluated in an intention-to-treat analysis, which, in this trial, was identical to an as-treated analysis. 108 patients (46.6%) were allotted to the intervention group. There were no statistically significant intergroup differences with respect to any clinical or histopathological criteria. A median of 16 lymph nodes were removed (interquartile range, 11-21). A symptomatic lymphocele arose in 1.3% (iT1) and 9.1% (iT2) of the patients, without any statistically significant difference between the two trial groups (p = 0.599 and p = 0.820, respectively). Nor did the groups differ significantly with respect to lymphocele volume (p = 0.670 on hospital discharge [T1], p = 0.650 90 days after surgery [T2]) or the type and frequency of need for subsequent surgical intervention (p = 0.535; iT2). 81.5% of all patients (n = 189) had no complications at all in the first three months after surgery. Nor were there any intergroup differences at 90 days with respect to the degree of stress urinary incontinence (p = 0.306) or complications (p = 0.486). CONCLUSION A peritoneal flap after RARP was not found to influence the rate of postoperative lymphocele, whether asymptomatic or requiring treatment.

Abstract
Radical prostatectomy (RP), performed as an open, laparoscopic or robotic procedure, remains the "gold standard" for patients with localised prostate cancer who can be cured with surgery and have a life expectancy of at least 10 years. Today, RP is also used as a first-line treatment for locally advanced prostate cancer, possibly in a multimodal setting with adjuvant radiation/hormonal therapy. The increasing experience of surgeons, better knowledge of anatomy and refinements of surgical techniques have greatly improved oncological and functional outcomes. In our article we would like to give an overview of the complications associated with this surgical procedure.

Abstract
OBJECTIVE The objective of the study was to evaluate the effect of peritoneal re-approximation at the end of the procedure in transperitoneal robot-assisted radical prostatectomy (tRARP) and extended pelvic lymphadenectomy (ePLND) on operative, oncologic, and symptomatic lymphocele rates. MATERIAL AND METHODS A total of 79 patients were included in the study who underwent tRARP and bilateral ePLND performed by two different experienced surgeons. One of the surgeons performed the peritoneal re-approximation (Group 1, n=41) and the other did not re-approximate the peritoneum (Group 2, n=38) at the end of the procedure in tRARP and ePLND. Operative parameters and symptomatic lymphocele rates were compared between the groups. RESULTS There were no significant differences between the preoperative parameters age, body mass index, and preoperative prostate-specific antigen values (p>0.05). The perioperative parameters were as follows: the operation time and estimated blood loss (EBL) was less, and the number of removed lymph nodes was higher in Group 2. However, only the difference in the EBL was statistically significant (p=0.03). Hospitalization time, symptomatic lymphocele, intervention requiring lymphocele, and complication rates were found to be less in Group 2, but only hospitalization time was statistically significant (p=0.04). Pathological parameters were similar for both groups. There was a significant correlation between lymph node positivity and the presence of symptomatic lymphocele in the correlation analysis (p=0.05). CONCLUSION It has been shown in this study that the re-approximation of the peritoneum does not provide any additional benefit in terms of complications. Considering that this process also increases the operation time and lymphocele formation, we think there is no need for re-approximation after robot-assisted radical prostatectomy and pelvic lymphadenectomy.

Abstract
Objectives: Robot-assisted radical prostatectomy (RARP) has been established as first-line surgical therapy for organ-confined prostate cancer (PCa). Pelvic lymph node dissection (PLND) is recommended in case of intermediate and high-risk localized PCa however symptomatic lymphocele (SL) formation is a common complication. Still no certain clinical and surgical predictors of SL have been found in the robotic era. Aim of this study was to identify clinical and surgical predictors of SL after RARP and PLND.Methods: We retrospectively evaluated all consecutive patients undergone RARP and PLND from 01/2017 to 06/2019, at our institution. All procedures were performed by experienced robotic surgeons. Baseline patients' characteristics, as well as peri- and post-operative features, were recorded and compared among those patients experiencing SL after surgery and those who did not.Results: Overall, 282 patients were included. Of these, 21 (7.5%) developed SL after surgery. Patients with SL showed higher median BMI (30.4 vs 25.8) and a more frequent history of vascular surgery or lymph-vascular disease (23.8% vs 8.4%) compared to patients without SL (p < 0.05). The lymphadenectomy technique adopted during the surgery was also found different in patients diagnosed with SL. At the multivariable analysis (MVA), only the increase of BMI (OR 1.72; CI: 1.47 - 2.81) was found predictor of developing SL.Conclusion: In our experience, the increase of BMI was a significant predictor of SL development in pCa patients submitted to RARP and PLND. This further evidence may be of great help for clinicians in daily clinical practice, in particular during preoperative counseling.

Abstract
OBJECTIVE To validate a nomogram predicting lymph node invasion (LNI) in prostate cancer patients undergoing radical prostatectomy taking into consideration multiparametric-magnetic resonance imaging (mp-MRI) parameters and targeted biopsies in a western European cohort. PATIENTS AND METHODS A total of 473 men diagnosed by targeted biopsies, using software-based MRI-ultrasound image fusion system, and operated by radical prostatectomy with extended pelvic lymph node dissection across 11 Europeans centers between 2012 and 2019 were identified. Area under the curve of the receiver operator characteristic curve, calibration plot and decision curve analysis were used to evaluated the performance of the model. RESULTS Overall, 56 (11.8%) patients had LNI on final pathologic examination with a median (IQR) of 13 (9-18) resected nodes. Significant differences (all P < 0.05) were found between patients with and without LNI in terms of preoperative PSA, clinical stage at DRE and mp-MRI, maximum diameter of the index lesion, PI-RADS score, Grade Group on systematic and targeted biopsies, total number of dissected lymph nodes, final pathologic staging and Grade Group. External validation of the prediction model showed a good accuracy with an area under the curve calculated as 0.8 (CI 95% 0.75-0.86). Graphic analysis of calibration plot and decision curve analysis showed a slight underestimation for predictive probability for LNI between 3% and 22% and a high net benefit. A cut-off at 7% was associated with a risk of missing LNI in 2.6%, avoiding unnecessary surgeries in 55.9%. CONCLUSIONS We report an external validation of the nomogram predicting LNI in patients treated with extended pelvic lymph node dissection in a western European cohort and a cut-off at 7% seems appropriate.

Abstract
BACKGROUND We investigated prognostic factors for biochemical recurrence (BCR) after robot-assisted radical prostatectomy (RARP) with extended pelvic lymph node (LN) dissection. METHODS We included 173 patients who underwent RARP with extended pelvic LN dissection without neoadjuvant therapy at our hospital between October 2010 and April 2018. BCR was defined as prostate serum antigen (PSA) levels ≥ 0.2 ng/mL; BCR-free survival rates were determined using Kaplan-Meier analysis. We used Cox regression analysis to evaluate effects of PSA and pathologic variables on BCR. RESULTS Median follow-up was 27.9 (range 6.1-86.9) months. Five-year BCR-free survival was 89.5%. In multivariate analysis, positive LNs (HR 7.117; 95% CI 2.826-17.925; P < 0.001) and Gleason score (GS) ≥ 8 (HR 2.612; 95% CI 1.051-6.489; P = 0.039) were significant predictors of BCR. Patients with 1 or 2 positive LNs (n = 10) had significantly higher BCR-free survival rates than patients with ≥ 3 positive LNs (n = 5). We, therefore, stratified the patients as low-risk (GS < 8 and no positive LNs), intermediate-risk: (either GS ≥ 8 or positive LNs) and high-risk (both GS ≥ 8 and positive LNs). Their 1-year BCR-free survival rates were low-risk: 94.6%, intermediate-risk: 88.5%, and high-risk: 33.3% (P < 0.05). CONCLUSIONS Patients with 1-2 positive LNs and GS < 8 have low risk for BCR; close observation without immediate adjuvant hormonal therapy can be considered for these patients.

Abstract
Prostate cancer is the most common noncutaneous malignancy in American men. Its lymphatic drainage is very well established throughout literature. We report the case of a 72-year-old Caucasian male with elevated serum prostate-specific antigen and biopsy-confirmed high-risk prostate cancer who underwent multiparametric magnetic resonance imaging (MRI) for staging and treatment planning. The imaging revealed suspicious lymph nodes in the left ischiorectal and right obturator fossae that were biopsy confirmed as metastatic prostate adenocarcinoma. Herein, we present the divergence from the well-established lymphatic drainage of prostate cancer and the role of MRI in detecting this prostate cancer site of spread.

Abstract
The practice of radical prostatectomy for treating prostate cancer has evolved remarkably since its general introduction around 1900. Initially described using a perineal approach, the procedure was later popularized using a retropubic one, after it was first described as such in 1948. The open surgical method has now largely been abandoned in favour of the minimally invasive robot-assisted method, which was first described in 2000. Until 1980, the procedure was hazardous, often accompanied by massive blood loss and poor outcomes. For patients in whom surgery is indicated, prostatectomy is increasingly being used as the first step in a multitherapeutic approach in advanced local, and even early metastatic, disease. However, contemporary molecular insights have enabled many men to safely avoid surgical intervention when the disease is phenotypically indolent and use of active surveillance programmes continues to expand worldwide. In 2020, surgery is not recommended in those men with low-grade, low-volume Gleason 6 prostate cancer; previously these men - a large cohort of ~40% of men with newly diagnosed prostate cancer - were offered surgery in large numbers, with little clinical benefit and considerable adverse effects. Radical prostatectomy is appropriate for men with intermediate-risk and high-risk disease (Gleason score 7-9 or Grade Groups 2-5) in whom radical prostatectomy prevents further metastatic seeding of potentially lethal clones of prostate cancer cells. Small series have suggested that it might be appropriate to offer radical prostatectomy to men presenting with small metastatic burden (nodal and or bone) as part of a multimodal therapeutic approach. Furthermore, surgical treatment of prostate cancer has been reported in cohorts of octogenarian men in good health with minimal comorbidities, when 20 years ago such men were rarely treated surgically even when diagnosed with localized high-risk disease. As medical therapies for prostate cancer continue to increase, the use of surgery might seem to be less relevant; however, the changing demographics of prostate cancer means that radical prostatectomy remains an important and useful option in many men, with a changing indication.

Abstract
Introduction The important part of radical prostatectomy (RP) for high risk (HR) is extended pelvic lymph node dissection (ePLND). This method consists of two stages of surgery usually performed at the compartment (pre- or transperineally). Aim We present our new combined technique of RP using two different approaches: a pre-peritoneal approach for laparoscopic radical prostatectomy (LRP) and a transperitoneal approach for ePLND. Material and methods This study included 30 patients aged 53 to 75 years (mean age: 64 years) with prostate cancer who underwent LRP and ePLND using a combined technique. After the pre-peritoneal LRP, transposition of the trocars into the peritoneal cavity was performed without changing their location, except the extreme left trocar, which was inserted through a new approach. Results The total duration of surgery was 155 to 290 min (mean: 215 min); ePLND lasted from 35 to 85 min (mean: 56 min). The movement of trocars into the peritoneal cavity was a very simple maneuver, taking up to 1 min without any complications. The number of removed lymph nodes (LNs) ranged from 13 to 28 (mean: 16.8). A positive margin was found in 5 (16%) patients. We recognized positive nodes in 9 (30%) patients. Conclusions The combined technique is both feasible and safe. Performing the most difficult maneuver, removal of the prostate, in the first stage appears to be more comfortable for the operator. The timing of the PLND stage in the combined technique and the number of removed LNs do not differ from the standard lenticular access.

Abstract
Purpose: Pelvic lymph node dissection is an important step during robotic radical prostatectomy. The collection of lymphatic fluid (lymphocele) is the most common complication with potentially severe impact; therefore, different strategies have been proposed to reduce its incidence. Materials and Methods: In this systematic review, EMBASE, MEDLINE, Cochrane Library, and NIH Registry of Clinical Trials were searched for articles including the following interventions: transperitoneal vs extraperitoneal approach, any reconfiguration of the peritoneum, the use of pelvic drains, and the use of different sealing techniques and sealing agents. The outcome evaluated was the incidence of symptomatic lymphocele. Randomized, nonrandomized, and/or retrospective studies were included. Results: Twelve studies were included (including one ongoing randomized clinical trial). Because of heterogeneity of included studies, no meta-analysis was performed. No significant impact was reported by different sealing techniques and agents or by surgical approach. Three retrospective, nonrandomized studies showed a potential benefit of peritoneal reconfiguration to maximize the peritoneal surface of reabsorption. Conclusion: Lymphocele formation is a multistep and multifactorial event; high-quality literature analyzing risk factors and preventive measures is rather scarce. Peritoneal reconfiguration could represent a reasonable option that deserves further evaluation; no other preventive measure is supported by current evidence.

Abstract
Introduction Prostate cancer (PCa) patients who are classified into the intermediate risk category represent a heterogeneous population needing further preoperative risk assessment. Objectives To evaluate clinical total testosterone (TT) associations with lymph node invasion (LNI) in intermediate risk PCa. Material and Methods Between November 2014 and July 2016, intermediate risk PCa was assessed in 154 patients who underwent extended pelvic lymph node dissection if the risk of LNI was higher than 5%. Clinical factors associated with the risk LNI were investigated by the multinomial logistic regression model. Results The risk of LNI was assessed higher than 5% in 40.9% of cases of whom 15.5% had LNI. In the multivariate model, the risk of LNI was independently increased by prostate specific antigen (OR = 1.185; p = 0.021) and TT (OR = 1.004; p = 0.036). As a result, TT was an independent factor that associated with LNI because it increased the risk of LNI by 4% for each increment unit of TT. Conclusion Preoperative TT independently increased the risk of LNI in the intermediate risk class of PCa patients elected to radical prostatectomy and extended pelvic lymph node dissection. TT might be a useful preoperative factor for stratifying intermediate risk patients because of the positive association of TT with high grade tumors.

Abstract
PURPOSE To evaluate the performance of the Zumsteg classification to estimate the risk of lymph-node invasion (LNI) compared with the Briganti nomogram (BN) in prostatectomy patients with intermediate-risk prostate cancer (IRPC). METHODS We included consecutive patients who had extended pelvic lymph-node dissection associated with radical prostatectomy for IRPC. To be classified favorable intermediate risk (FIR), patients could only have one intermediate-risk factor, fewer than 50% positive biopsies and no primary Gleason score of 4. RESULTS On the 387 patients included, 149 (38.5%) and 238 (54.3%) were classified FIR and unfavorable intermediate risk (UIR), respectively, and 212 (54.8%) had a BN inferior to 5%. Thirty-eight patients (9.8%) had LNI: 6 FIR patients (4.0%) versus 32 UIR patients (13.4%) and 14 patients (6.6%) with a BN inferior to 5% versus 24 patients (13.7%) with a BN superior to 5%. Eight patients with a BN inferior to 5%, but classified UIR, had LNI. Sensitivity to detect LNI was higher with the Zumsteg classification than with the BN: 84.2% (CI 95% [68-93]) versus 63.2% (CI 95% [46-78]). Both screening tests were concordant to predict LNI (kappa coefficient of 0.076, p < 0.05 for Zumsteg and Briganti) CONCLUSIONS: Zumsteg classification appeared to be more sensitive and as effective (despite the impossibility to make decision curve analysis) than the BN to estimate the risk of LNI. Regarding the modest number of pN+ patients, further studies are needed to see the interest of proposing ePLND for UIR patients only.

Abstract
INTRODUCTION Radical prostatectomy with extended pelvic lymph node dissection (ePLND) is a curative treatment option for patients with clinically significant localised prostate cancer. The decision to perform an ePLND can be challenging because the overall incidence of lymph node metastasis is relatively low and ePLND is not free of complications. Using current clinical nomograms to identify patients with nodal involvement, approximately 75-85% of ePLNDs performed are negative. The aim of this study was to assess the added value of 68Ga-PSMA-11 PET in predicting lymph node metastasis in men with intermediate- or high-risk prostate cancer. METHODS 68Ga-PSMA-11 PET scans of 60 patients undergoing radical prostatectomy with ePLND were reviewed for qualitative (visual) assessment of suspicious nodes and assessment of quantitative parameters of the primary tumour in the prostate (SUVmax, total activity (PSMAtotal) and PSMA positive volume (PSMAvol)). Ability of quantitative PET parameters to predict nodal metastasis was assessed with receiver operating characteristics (ROC) analysis. A multivariable logistic regression model combining PSA, Gleason score, visual nodal status on PET and primary tumour PSMAtotal was built. Net benefit at each risk threshold was compared with five nomograms: MSKCC nomogram, Yale formula, Roach formula, Winter nomogram and Partin tables (2016). RESULTS Overall, pathology of ePLND specimens revealed 31 pelvic metastatic lymph nodes in 12 patients. 68Ga-PSMA-11 PET visual analysis correctly detected suspicious nodes in 7 patients, yielding a sensitivity of 58% and a specificity of 98%. The area under the ROC curve for primary tumour SUVmax was 0.70, for PSMAtotal 0.76 and for PSMAvol 0.75. The optimal cut-off for nodal involvement was PSMAtotal > 49.1. The PET model including PSA, Gleason score and quantitative PET parameters had a persistently higher net benefit compared with all clinical nomograms. CONCLUSION Our model combining PSA, Gleason score and visual lymph node analysis on 68Ga-PSMA-11 PET with PSMAtotal of the primary tumour showed a tendency to improve patient selection for ePLND over the currently used clinical nomograms. Although this result has to be validated, 68Ga-PSMA-11 PET showed the potential to reduce unnecessary surgical procedures in patients with intermediate- or high-risk prostate cancer.

Abstract
OBJECTIVES To develop a machine learning (ML)-assisted model to identify candidates for extended pelvic lymph node dissection (ePLND) in prostate cancer by integrating clinical, biopsy, and precisely defined magnetic resonance imaging (MRI) findings. PATIENTS AND METHODS In all, 248 patients treated with radical prostatectomy and ePLND or PLND were included. ML-assisted models were developed from 18 integrated features using logistic regression (LR), support vector machine (SVM), and random forests (RFs). The models were compared to the Memorial SloanKettering Cancer Center (MSKCC) nomogram using receiver operating characteristic-derived area under the curve (AUC) calibration plots and decision curve analysis (DCA). RESULTS A total of 59/248 (23.8%) lymph node invasions (LNIs) were identified at surgery. The predictive accuracy of the ML-based models, with (+) or without (-) MRI-reported LNI, yielded similar AUCs (RFs+ /RFs- : 0.906/0.885; SVM+ /SVM- : 0.891/0.868; LR+ /LR- : 0.886/0.882) and were higher than the MSKCC nomogram (0.816; P < 0.001). The calibration of the MSKCC nomogram tended to underestimate LNI risk across the entire range of predicted probabilities compared to the ML-assisted models. The DCA showed that the ML-assisted models significantly improved risk prediction at a risk threshold of ≤80% compared to the MSKCC nomogram. If ePLNDs missed was controlled at <3%, both RFs+ and RFs- resulted in a higher positive predictive value (51.4%/49.6% vs 40.3%), similar negative predictive value (97.2%/97.8% vs 97.2%), and higher number of ePLNDs spared (56.9%/54.4% vs 43.9%) compared to the MSKCC nomogram. CONCLUSIONS Our ML-based model, with a 5-15% cutoff, is superior to the MSKCC nomogram, sparing ≥50% of ePLNDs with a risk of missing <3% of LNIs.

Abstract
PURPOSE Differences exist concerning when and how to perform lymph node dissection (LND) during radical prostatectomy due to lack of high-grade evidence to its safety and efficacy. We aimed to compare readmission rates between limited and extended LND during open radical prostatectomy (ORP) and robot-assisted radical prostatectomy (RARP). MATERIALS AND METHODS We conducted a prospective trial of 3,706 eligible patients comparing ORP vs. RARP (LAPPRO). Six hundred and twenty-seven underwent concomitant LND. Data were retrieved for readmissions within 90 days from surgery from the Swedish Patient Registry. Causes for readmissions were classified according to the modified Clavien-Dindo classification system. We estimated risks for readmission stratified by type of LND and surgical approach. RESULTS We recorded 107 readmissions in 90 patients. The overall readmission rate was 14% (90/627). In the open group, extended LND had a higher, but not statistically significant readmission rate of 18% compared to 11% after limited LND (95%CI 0.87-3.01). In the robot-assisted group, readmissions after extended LND did not differ from limited LND (15% vs. 18%, 95%CI 0.49-1.61). RARP with limited LND showed a higher risk for any (RR 1.98, 95%CI [1.02-3.81]) as well as Clavien-Dindo grade 1 to 2 readmissions (RR 2.49, 95%CI [1.10-5.63]) compared to open approach with limited LND. Robot-assisted extended LND reduced the risk for Clavien-Dindo grade 3 to 5 complications leading to readmissions compared to the open approach by 59% (RR 0.41, 95%CI [0.19-0.87]). CONCLUSIONS The risk for hospital readmission was similar when performing limited or extended LND during a radical prostatectomy. Robot-assisted technique for performing extended LND may decrease the risk for severe complications.

Abstract
Objective: To investigate by means of a randomized clinical trial the safety of no drain in the pelvic cavity after robot-assisted radical prostatectomy (RARP) with or without extended pelvic lymph node dissection (ePLND). Materials and Methods: From May to December 2016, 112 consecutive patients who underwent RARP with or without ePLND were prospectively randomized into a control group (CG) and study group (SG). In the CG, a drain was placed in the pelvic cavity at the end of surgery and removed after 24 hours. The trial was designed to assess noninferiority. The primary endpoint was evaluated as complication rates graded by the Clavien-Dindo score (CDS). Secondary endpoints included length of hospital stay (LOHS) and hospital readmission (RAD). Results and Limitations: At final analysis, 56 patients were in the CG and 54 belonged to the SG. The groups were homogenous for all preoperative and perioperative variables and did not show any difference in CDS complication rates (28.9% in the CG and 20.4% in the SG; p = 0.254), LOHS (on average 4 days in each group; p = 0.689), and RAD rates (3.6% in the CG and 3.7% in the SG; p = 0.970). Conclusions: In a modern cohort of patients who underwent RARP with or without ePLND, a single-center randomized controlled trial showed that no-drain policy is equivalent to drain after RARP in terms of CDS complication rate, LOHS, and RAD rate. The option of placing a postoperative drain for the first 24 hours could be considered in cases of difficult urethrovesical anastomosis with uncertain watertightness.

Abstract
BACKGROUND High-grade prostate cancer (PCa) has a poor prognosis, and up to 15% of patients worldwide experience lymph node invasion (LNI). To further improve the prediction lymph node invasion in prostate cancer, we adopted risk scores of the genes expression based on the nomogram in guidelines. METHODS We analyzed clinical data from 320 PCa patients from the Cancer Genome Atlas database. Weighted gene coexpression network analysis was used to identify the genes that were significantly associated with LNI in PCa (n = 390). Analyses using the Gene Ontology and Kyoto Encyclopedia of Genes and Genomes databases were performed to identify the activated signaling pathways. Univariate and multivariate logistic regression analyses were performed to identify the independent risk factors for the presence of LNI. RESULTS We found that patients with actual LNI and predicted LNI had the worst survival outcomes. The 7 most significant genes (CTNNAL1, ENSA, MAP6D1, MBD4, PRCC, SF3B2, TREML1) were selected for further analysis. Pathways in the cell cycle, DNA replication, oocyte meiosis, and 9 other pathways were dramatically activated during LNI in PCa. Multivariate analyses identified that the risk score (odds ratio [OR] = 1.05 for 1% increase, 95% confidence interval [CI]: 1.04-1.07, P < .001), serum PSA level, clinical stage, primary biopsy Gleason grade (OR = 2.52 for a grade increase, 95% CI: 1.27-5.22, P = .096), and secondary biopsy Gleason grade were independent predictors of LNI. A nomogram built using these predictive variables showed good calibration and a net clinical benefit, with an area under the curve (AUC) value of 90.2%. CONCLUSIONS In clinical practice, the application of our nomogram might contribute significantly to the selection of patients who are good candidates for surgery with extended pelvic lymph node dissection.

Abstract
BACKGROUND The aim of this study was to investigate the risk factors contributing to multiple lymph node invasion (LNI) in patients with prostate cancer (PCa) undergoing extended pelvic lymph node dissection (ePLND) during robot assisted radical prostatectomy (RARP). METHODS A total of 211 patients who underwent RARP and ePNLD from June 2013 to March 2017 were classified according to lymph node status in the surgical specimen (absent, single or multiple). Risk factors of LNI were evaluated by the multinomial logistic regression model. A receiver operating characteristic (ROC) curve and area under the curve (AUC) were used to assess the efficacy of factors and model evaluation. RESULTS On multivariate analysis, the risk of multiple LNI, was independently increased by Body Mass Index (BMI) (odds ratio [OR] 1.194; P=0.026) and prostate-specific antigen (PSA) (OR=1.089; P=0.014) when compared to patients without LNI. ROC curves indicated that both BMI (AUC=0.702) and PSA (AUC=0.732) had fair discrimination power. For each unit of increase in PSA, the odds of multiple lymph node invasion increased by 8.9% and for each unit increase of BMI, the odds of multiple LNI increased by 19.4%. CONCLUSIONS The risk of multiple LNI was independently predicted by PSA and BMI with fair discrimination power.

Abstract
Emerging evidence has suggested that cytoreductive prostatectomy (CRP) allows superior oncologic control when compared to current standard of care androgen deprivation therapy alone. However, the safety and benefit of cytoreduction in metastatic prostate cancer (mPCa) has not been proven. Therefore, we evaluated the incidence of complications following CRP in men newly diagnosed with mPCa. A total of 68 patients who underwent CRP from 2006 to 2014 at four tertiary surgical centers were compared to 598 men who underwent radical prostatectomy for clinically localized prostate cancer (PCa). Urinary incontinence was defined as the use of any pad. CRP had longer operative times (200 min vs 140 min, P < 0.0001) and higher estimated blood loss (250 ml vs 125 ml, P < 0.0001) compared to the control group. However, both overall (8.82% vs 5.85%) and major complication rates (4.41% vs 2.17%) were comparable between the two groups. Importantly, urinary incontinence rate at 1-year after surgery was significantly higher in the CRP group (57.4% vs 90.8%, P < 0.0001). Univariate logistic analysis showed that the estimated blood loss was the only independent predictor of perioperative complications both in the unadjusted model (OR: 1.18; 95% CI: 1.02–1.37; P = 0.025) and surgery type-adjusted model (OR: 1.17; 95% CI: 1.01–1.36; P = 0.034). In conclusion, CRP is more challenging than radical prostatectomy and associated with a notably higher incidence of urinary incontinence. Nevertheless, CRP is a technically feasible and safe surgery for selecting PCa patients who present with node-positive or bony metastasis when performed by experienced surgeons. A prospective, multi-institutional clinical trial is currently underway to verify this concept.

Abstract
BACKGROUND The aim of this study was to evaluate intra- and perioperative outcomes of a single high volume open radical prostatectomy (ORP) surgeon, during his learning curve period for robot-assisted radical prostatectomy (RARP) and extended pelvic lymph node dissection (ePLND). METHODS The study included 264 intermediate-high risk prostate cancer patients, treated by ORP + ePLND or RARP + ePLND, prospectively collected. Descriptive statistics compared clinical and pathological variables between groups. Bivariate (Pearson) correlation analysis assessed the relationship between the number of lymph node (LN) removed, positive surgical margins (PSM), surgical time and the number of procedures performed per group. RESULTS pT stage and Gleason score (GS) were lower in RARP than in ORP group (both P=0.04), while PSM were more frequent in the RARP group (40% vs. 25%; P=0.02). However, PSM decreased with the increase of RARP procedures. The number of LNs removed was 25 and 22, in RARP and ORP group (P=0.03). However, LN+ rate did not differ between groups (11% vs. 16%; P=0.216). In the RARP group, overall surgical time and ePLND time decreased with the increase of surgical procedures (all P<0.001). CONCLUSIONS RARP requires significant learning curve to reduce operative room time and obtain PSM comparable to those of an ORP high-volume surgeon. On the contrary, the quality of ePLND during RARP seems to be not related to the number of procedures performed, allowing removal of a number of LNs that is clinically comparable to ORP.

Abstract
Lymphocele formation is the most common adverse event of pelvic lymphadenectomy during radical prostatectomy for prostate cancer. Previous studies failed to favor one surgical technique over the other in terms of minimizing its rate. Data on risk factors for its development are still conflicting and warranting further research. In this mini-review, we aimed to scrutinize available evidence on these aspects and outline current achievements in lymphocele prevention approaches.

Abstract
BACKGROUND To evaluate the morbidity of different surgical approaches for pelvic lymph node dissection (PLND), to evaluate the influence of morbidity on radiotherapy (RT) planning and to evaluate a possible therapeutic effect of a more extensive yield of PLND. METHODS From 2000-2016, 228 patients received staging PLND before primary RT in a single tertiary care center. Nine patients were excluded for the evaluation of morbidity. Fifty patients were operated in an open approach, 96 laparoscopic and 73 robot-assisted (RA). Clavien-Dindo classification was used for evaluating complications. Predictors of biochemical recurrence (BCR), clinical relapse (CR), cancer-specific survival (CSS) and overall survival (OS) were evaluated by regression analyses to determine a possible therapeutic effect. RESULTS Minimal invasive surgery (laparoscopic or RA) caused five times less major complications (22% vs. 4.3%, p = .001) and a median 3 days shorter hospital stay (5 days versus 2 days, p < .001). Major complications resulted in a delayed (23 days, p < .001) RT start but no oncological effect was seen. Independent oncological predictors were the number of positive nodes (BCR, CR, CSS, OS), a lower age (CR), a higher level of initial prostate-specific antigen (PSA) (BCR) and post-RT PSA (BCR). CONCLUSION Minimal invasive surgery can diminish major complications which delay RT start. Nodal staging proved to be of importance for prognosis but no therapeutic effect was seen of performing PLND as such.

Abstract
PURPOSE To retrospectively evaluate the short-term outcomes of lymphangiography and lymphatic embolization in the treatment of pelvic lymphocele after radical prostatectomy in patients with prostate cancer. MATERIALS AND METHODS The data of nine, consecutive patients who underwent lymphangiography and lymphatic embolization for pelvic lymphocele after radical prostatectomy with pelvic lymph node dissection (PLND) between January 2016 and May 2018, were retrospectively reviewed. Lymphangiography was performed through inguinal lymph nodes in order to identify the lymphatic leakage. When a leakage was found, lymphatic embolization was performed using a directly punctured fine needle at the closest upstream lymph node or lymphopseudoaneurysm and with N-butyl cyanoacrylate glue. RESULTS Lymphangiography demonstrated extravasation and/or lymphopseudoaneurysm in all of these patients. A total of 13 sessions of lymphangiography and lymphatic embolization were performed. The median number of lymphangiography and lymphatic embolizations required to achieve clinical success was one (range, 1-3). Three patients underwent repeated embolization with successful results. The technical and clinical success rates were 100%, respectively. The median time to resolution was 7 days (range, 2-19 days). There was no recurrence and no procedure-related complications during the follow-up period (mean, 26 weeks; range, 8-77 weeks) in all patients. CONCLUSIONS Lymphangiography and lymphatic embolization are safe and effective for the management of pelvic lymphoceles after radical prostatectomy with PLND.

Abstract
Introduction: Lymph node metastases (LNM) represent a proven prognostic factor for biochemical recurrence (BCR)-free survival, metastatic free survival and overall survival in prostate cancer (PCa). Although pelvic node dissection remains the gold standard for the detection of LNM, novel imaging techniques are entering clinical practice, in the effort to improve LNM detection and spare unnecessary surgeries. Aim of the current review is to describe such imaging techniques and explore their advantages and limitations. Evidence Acquisition: The National Library of Medicine Database was searched for relevant articles published between January 2013 and August 2018. A wide search was performed including the combination of following words: “Prostate” and “Cancer” and “staging” and “Lymph Node” and “imaging” and (“MRI” or “PET”). The initial list of selected papers was enriched by individual suggestions of the authors of the present review. Evidence Synthesis: DWI-MRI in detection of lymph node invasion has a sensitivity and specificity of 41 and 94%, respectively. For SPIO MRI using ferumoxtran-10, the sensitivity for detection of LNM with short axis diameter of 5–10 mm is reported at 96.4%, compared to 28.5% with MRI alone. PSMA PET/CT is growing exponentially, both in the initial detection of LNM and for BCR evaluation. Fluciclovine PET could improve detection of subcentimetric pathologic lymph nodes. Sentinel lymph node techniques remain experimental and not validated in the field of PCa. Conclusions: Molecular imaging, particularly PSMA ligand PET imaging, present interesting diagnostic accuracy in LN diagnosis even in subcentimetric LN. DWI-MRI yields good results in LN involvement evaluation and the use of contrast agent such SPIO may improve the detection rate. The SLN technique is limited to experimental protocols and for intermediate or high-risk PCa. Prospective trials are awaited to evaluate the true clinical impact of these imaging techniques on PCa oncologic outcomes.

Abstract
BACKGROUND Lymph node detection in prostate cancer is challenging and critical to determine treatment policy. Choline PET/CT (positron emission tomography/computed tomography) and magnetic resonance imaging (MRI) have been used for the evaluation of lymph node metastasis in patients with prostate cancer for the past decade. However, only limited patients underwent direct comparison studies. PURPOSE To evaluate the diagnostic performance of choline PET/CT compared with MRI imaging for detecting lymph node metastases in prostate cancer patients. MATERIAL AND METHODS Relevant English-language articles published before February 2018 were searched in PubMed database, Embase database, and Cochrane Library databases search using the keywords: (Prostate Neoplasm OR Prostate Cancer OR prostate carcinoma) and (Lymph Node) and (PET/CT OR positron emission tomography/computed tomography) and (choline or 2-hydroxy-N,N,N-trimethylethanaminium) and (magnetic resonance imaging OR MRI). Articles were included that directly compare the diagnostic performance and clinical utility of choline PET/CT and MRI for detecting lymph node metastases in prostate cancer patients. Study quality was assessed with QUADAS criteria. Analyses were performed on a per patient and a per node basis. The pooled sensitivity, specificity, diagnostic odds ratio (DOR), positive likelihood ratio (LR+), and negative likelihood ratio (LR-) were calculated using Meta-Disc 1.4 software. Summary receiver-operating characteristic (SROC) curves constructed. RESULTS A total of 362 patients from 8 studies involving fulfilled the inclusion criteria. On patient-based analysis, the pooled sensitivity, specificity, and DOR with a 95% confidence interval (CI) for choline PET/CT imaging were 0.59 (95%CI, 0.50-0.67), 0.92 (95%CI, 0.87-0.96), 17.37 (95%CI, 4.42-68.33), and for MRI imaging, they were 0.52 (95%CI, 0.44-0.61), 0.87 (95%CI, 0.81-0.92), 6.05 (95%CI, 3.09-11.85), respectively. On node-based, the corresponding values for choline PET/CT imaging were 0.51 (95%CI, 0.46-0.57), 0.99 (95%CI, 0.98-0.99), 65.55 (95%CI, 23.55-182.45), and for MRI imaging, they were 0.39 (95%CI, 0.34-0.44), 0.97 (95%CI, 0.96-0.97), 15.86 (95%CI, 8.96-28.05), respectively. CONCLUSION Choline PET/CT performed better than MRI imaging in evaluating the lymph nodes metastasis of prostate cancer patients and had the potential to be broadly applied in clinical practice.

Abstract
Lymph node dissection (LND) represents a critical step in order to determine lymph node invasion (LNI), not only for prognostic means but also as a therapeutic strategy in the management of patients with prostate cancer (CaP). Indications for performing LND are inconsistent with the American Urologic Association (AUA), European Association of Urology (EAU), and National Comprehensive Cancer Network (NCCN) recommendations differing. A thorough appreciation of lymph node drainage patterns and extent of LND has reshaped our understanding of this disease. Moreover, newer research into this field has directly resulted in refinements to current nomograms with utilization of various prostate-specific antigen (PSA) parameters and genomic medicine. Lastly, the application of newer imaging modalities in combination with molecular-guided robotic surgery has personalized the approach of LND espousing excellent safety, efficacy, and oncologic outcomes in these patients.

The age of robotic surgery - Is laparoscopy dead? Arab J Urol 2018; 16:262-269. [PMID: 30140462 PMCID: PMC6104663 DOI: 10.1016/j.aju.2018.07.003] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2018] [Revised: 06/24/2018] [Accepted: 07/10/2018] [Indexed: 01/06/2023] Open
Abstract
Introduction Robot-assisted laparoscopic surgery (RALS) has become a widely used technology in urology. Urological procedures that are now being routinely performed robotically are: radical prostatectomy (RP), radical cystectomy (RC), renal procedures - mainly partial nephrectomy (PN), and pyeloplasty, as well as ureteric re-implantation and adrenalectomy. Methods This non-systematic review of the literature examines the effectiveness of RALS compared with conventional laparoscopic surgery for the most relevant urological procedures. Results For robot-assisted RP there seems to be an advantage in terms of continence and potency over laparoscopy. Robot-assisted RC seems equal in terms of oncological outcome but with lower complication rates; however, the effect of intracorporeal urinary diversion has hardly been examined. Robotic PN has proven safe and is most likely superior to conventional laparoscopy, whereas there does not seem to be a real advantage for the robot in radical nephrectomy. For reconstructive procedures, e.g. pyeloplasty and ureteric re-implantation, there seems to be advantages in terms of operating time. Conclusions We found substantial, albeit mostly low-quality evidence, that robotic operations can have better outcomes than procedures performed laparoscopically. However, in light of the significant costs and because high-quality data from prospective randomised trials are still missing, conventional urological laparoscopy is certainly not 'dead' yet.

Abstract
INTRODUCTION The extent of lymph node dissection (LND) and its potential survival benefit are still a matter of debate. Aim of our review was to summarize the latest literature data regarding the surgical templates, the potential oncological benefits, the functional outcomes and the complications of extended lymph node dissection (eLND) during robot-assisted radical prostatectomy (RARP). EVIDENCE ACQUISITION We systematically reviewed all relevant studies using PubMed, MEDLINE, Embase, American Urological Association (AUA), European Society of Medical Oncology (ESMO) and European Association of Urology (EAU) guidelines. EVIDENCE SYNTHESIS A narrative synthesis of all relevant publications on surgical templates, complications, oncological and functional outcomes of robot assisted eLND was undertaken. CONCLUSIONS A great deal of evidence supports that an extended template of LND is not only technically feasible but also safe in the context of RARP. It is really promising that in the era of minimally invasive surgery, parameters like the lymph node yield and the detection rates of positive lymph nodes during LND have become highly comparable with open series. The extended approach has already proved its benefits in terms of proper patient staging but more studies are needed with regard to functional outcomes and oncological benefits of this procedure.

Abstract
BACKGROUND Multiple statistical models predicting lymph node involvement (LNI) in prostate cancer (PCa) exist to support clinical decision-making regarding extended pelvic lymph node dissection (ePLND). OBJECTIVE To validate models predicting LNI in Dutch PCa patients. DESIGN, SETTING, AND PARTICIPANTS Sixteen prediction models were validated using a patient cohort of 1001 men who underwent ePLND. Patient characteristics included serum prostate specific antigen (PSA), cT stage, primary and secondary Gleason scores, number of biopsy cores taken, and number of positive biopsy cores. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Model performance was assessed using the area under the receiver operating characteristic curve (AUC). Calibration plots were used to visualize over- or underestimation by the models. RESULTS AND LIMITATIONS LNI was identified in 276 patients (28%). Patients with LNI had higher PSA, higher primary Gleason pattern, higher Gleason score, higher number of nodes harvested, higher number of positive biopsy cores, and higher cT stage compared to patients without LNI. Predictions generated by the 2012 Briganti nomogram (AUC 0.76) and the Memorial Sloan Kettering Cancer Center (MSKCC) web calculator (AUC 0.75) were the most accurate. Calibration had a decisive role in selecting the most accurate models because of overlapping confidence intervals for the AUCs. Underestimation of LNI probability in patients had a predicted probability of <20%. The omission of model updating was a limitation of the study. CONCLUSIONS Models predicting LNI in PCa patients were externally validated in a Dutch patient cohort. The 2012 Briganti and MSKCC nomograms were identified as the most accurate prediction models available. PATIENT SUMMARY In this report we looked at how well models were able to predict the risk of prostate cancer spreading to the pelvic lymph nodes. We found that two models performed similarly in predicting the most accurate probabilities.

Abstract
The aim of this study is to identify optimal patients for adjuvant radiation therapy (ART) in pT3 prostate cancer. The role of ART for patients with adverse pathologic features after radical prostatectomy (RP) has been demonstrated, but over- or under-treatment remains a significant concern. Two-hundred and five patients with pT3N0M0 who underwent robot-assisted RP without ART were analyzed. Multivariate Cox proportional regression analyses were used to identify predictors of biochemical recurrence (BCR) and clinical progression (CP). The estimated 5-year BCR-free survival (BCRFS) and CP-free survival (CPFS) were 52.8% and 85.6%, respectively. Preoperative prostate-specifc antigen (PSA) ≥10 ng ml-1 (hazard ratio [HR]: 3.288-6.027; P = 0.003), pathologic Gleason score (pGS) ≥8 (HR: 4.146; P = 0.014), and lymphovascular invasion (LVI) (HR: 2.167; P = 0.026) were associated with BCR. Based on these factors, a risk stratification tool was developed. Patients with no risk factors (PSA <10 ng ml-1 , pGS 6, and absent LVI) showed excellent BCRFS and CPFS at 5 years (91.9% and 100.0%, respectively), but those with two or more risk factors (PSA ≥10 ng ml-1 , pGS ≥8, or present LVI) had poor BCRFS and CPFS (12.1% and 54.6%, respectively). In addition, the multivariate analysis revealed that pathologic stage pT3b (HR: 5.393; P = 0.025) was the only predictor of CP. Our study demonstrated the heterogeneity of oncologic outcomes in patients with pT3 prostate cancer. The proposed risk stratification can be used to identify patients who are at risk for disease progression and may aid in identifying the best patients for ART.

Abstract
BACKGROUND Symptomatic lymphocele following radical prostatectomy (RP) and concomitant bilateral extended pelvic lymph node dissection (ePLND) has a significant impact on postoperative recovery and may sometimes require surgical intervention. OBJECTIVE To report on the use of four-point peritoneal flap fixation (4PPFF) during RP to reduce lymphocele occurrence following PLND. DESIGN, SETTING, AND PARTICIPANTS Between April 2010 and May 2017, 1358 patients underwent RP with concomitant bilateral ePLND. From this cohort, 193 patients who had undergone PNLD with 4PPFF were matched in a 1:1 ratio with respect to age, body mass index, initial PSA, and number of lymph nodes removed to patients who had undergone PLND without 4PPFF. INTERVENTION 4PPFF was performed by suturing the cut end of the ventral parietal peritoneum at four points (to the anterior and lateral pelvic side wall on both sides) following PLND so that the peritoneal surface was exposed to the iliac vessels and obturator fossa. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS All patients underwent ultrasound on postoperative days 6, 28, and 90 to test for the presence of lymphocele. For univariate analysis, a χ2 test and analysis of variance were applied, as appropriate. Statistical significance was set at p<0.05, and all p values reported were two-sided. RESULTS AND LIMITATIONS There were no significant differences between the two groups with respect to intraoperative blood loss, positive surgical margin rate, Gleason score, clinical stage, and number of positive cores. Asymptomatic lymphocele was observed in four patients (2.07%) in the 4PPFF group compared to 16 patients (8.3%) without 4PPFF (p=0.0058). Similarly, a significant difference in the incidence of symptomatic lymphocele was observed: two patients (1.03%) in the 4PPFF group versus nine patients (4.6%) without 4PPFF (p=0.0322). There were no differences in other complication rates between the two groups. The limitations of the study are its retrospective and nonrandomised nature, with postoperative follow-up based on ultrasound imaging rather than computed tomography because of ethical considerations, which could have caused observer bias. CONCLUSIONS 4PPFF is a safe and effective procedure in preventing lymphocele occurrence in patients undergoing RP with PLND. The increase in exposure of the PLND raw area to the peritoneal surface following this procedure may aid in increased absorption of accumulating lymph fluid. Further prospective randomised multicentre studies are warranted to confirm our observations. PATIENT SUMMARY We report on the use of a surgical technique to decrease the collection of lymphatic fluid in the abdominal cavity following lymph node removal during radical removal of the prostate gland in patients with prostate cancer. Patients undergoing this procedure had significantly better outcomes when compared to patients operated on in the conventional approach.

Abstract
Robot assisted radical prostatectomy (RARP) with extensive pelvic lymph node dissection (ePLND) is an effective procedure for treating and staging prostate cancer; however, high grade complications represent a critical issue. To investigate clinical factors associated with the risk of Clavien-Dindo grade 3 complications in patients undergoing RARP with ePLND. The study included 211 consecutive patients who were operated in a period running from June 2013 to March 2017. Factors associated with grade 3 complications were evaluated by the logistic regression model. Receiver operating characteristic curves and area under the curve (AUC) were used to assess the risk model. Of the 211 patients included in the study, 55 (26.1%) had complications, which were classified Clavien grade one in 36 cases (17.1%), two in 7 (3.3%), 3a in 9 (4.3%) and 3b in 3 (1.4%). Higher median measurements of body mass index (BMI) were detected in grade 3 subjects (27.6 kg/m2) when compared to grade 0-2 cases (25 kg/m2) and the difference was significant (P = 0.015). BMI increased the risk of high grade complications (odds ratio, OR 1.184; P = 0.047) with a fair discrimination power (AUC 0.709). It generated a risk curve by the model, which stratified patients in low (BMI < 26 kg/m2; probability risk less than 5%), intermediate (26 ≤ BMI (kg/m2) ≤ 30; risk between 5 and 10%), and high (BMI > 30 kg/m2; risk between 10 and 20%) risk classes for grade 3 complications. BMI is an independent predictor of grade 3 complications, which are increased by 18.4% for each unit rise. Patients may be stratified preoperatively by BMI into grade 3 risk categories, which include low (normal weight), intermediate (overweight), and high (obese) risk cases.
