Assessment of the Anastomosis after Radical Prostatectomy: A Review of Available Diagnostic Methods.

INTRODUCTION: After radical prostatectomy, many institutions perform cystography to exclude vesicourethral anastomotic leakage before removing a urethral catheter. We reviewed diagnostic methods to exclude leakage compared to the reference standard cystography. METHODS: We performed systematic literature review to summarize the published options and outcomes for assessment of vesicourethral anastomotic leakage after radical prostatectomy. RESULTS: Of 2,137 publications, 45 full-text manuscripts underwent full-text screening, of which 9 studies contributing 919 patients were included. Seven studies described ultrasound-guided assessment (four transrectal, two transabdominal, one transperineal). Two further studies described the use of computerized tomography. Ultrasound-guided assessment of the anastomosis after radical prostatectomy shows promising agreement with cystography. Computerized tomography-aided assessment of vesicourethral anastomosis detects more leakages; however, clinical consequences are not defined. CONCLUSION: Further studies are warranted to (1) identify men at risk of anastomotic leakage who should undergo assessment before trial without a catheter and (2) provide prospective comparisons of different ultrasound-guided approaches.

Low Risk of Venous Thromboembolism After Robot-assisted Radical Prostatectomy Through Systemic Image Assessment: A Prospective Study.

BACKGROUND/AIM: The aim of the study was to evaluate the risk of venous thromboembolism (VTE) after robot-assisted radical prostatectomy (RARP) and discuss whether a uniform prophylaxis for VTE after radical prostatectomy is also suitable for robotic surgery. On this context, we investigated the incidence and risk factors of VTE, including asymptomatic events, after RARP compared to transurethral resection of bladder tumor (TUR-BT). PATIENTS AND METHODS: The participants were 209 patients with localized prostate cancer who underwent RARP, and 93 patients who underwent TUR-BT as controls. The incidence and risk factors of VTE, including deep vein thrombosis and pulmonary embolism, were systemically investigated seven days after surgery using contrast-enhanced computed tomography. RESULTS: Of the 209 RARP patients, 5.7% (12/209) patients had VTE. All events were asymptomatic and the incidence of VTE was not significantly different between the two surgeries (p=0.90). In multivariate analyses, neoadjuvant androgen deprivation therapy (ADT) (p=0.006), D-dimer value on postoperative day 1 (p=0.001) and lymphocele formation (p=0.043) were significantly associated with VTE after RARP. CONCLUSION: The risk of VTE after RARP might not be so high and uniform prophylaxis might not be suitable for RARP because it might be the same as that after transurethral resection for bladder tumors. However, neoadjuvant ADT, high D-dimer levels after surgery and lymphocele formation should be noted as risk factors of VTE after RARP.

Medico-economic impact of onco-urological robot-assisted minimally invasive surgery in a high-volume centre.

BACKGROUND: We lack data regarding the economic cost of robot-assisted surgical procedures in urology. We aimed to assess the medico-economic impact of onco-urological robot-assisted surgery. METHODS: All patients who underwent robot-assisted radical prostatectomy (RARP) or robot-assisted partial nephrectomy (RAPN) in 2019 were included. Cost assessment included the costs of surgery, hospital stay, and complications. Global cost was calculated and compared with open and laparoscopic procedures. RESULTS: Overall, 126 (48%) RAPN and 135 (52%) RARP were included. Total cost per patient was 6857€ for RARP and 6034€ for RAPN. Costs of surgery, hospital stay, and complications represented 76.2%, 21.5%, and 2.3%, respectively, of the total cost per patient for RAPN, and 74.1%, 25.9%, and 0% for RARP. Compared to the open approach, RAPN was 6% cheaper and RARP was 10% more expensive per patient. Standard laparoscopic procedures were cheaper. CONCLUSIONS: Robotic procedures were associated with increased costs of surgical procedures, but with reduction in morbidity and hospital stay costs.

Systematic literature review of cost-effectiveness analyses of robotic-assisted radical prostatectomy for localised prostate cancer.

OBJECTIVES: Review and assess cost-effectiveness studies of robotic-assisted radical prostatectomy (RARP) for localised prostate cancer compared with open radical prostatectomy (ORP) and laparoscopic radical prostatectomy (LRP). DESIGN: Systematic review. SETTING: PubMed, Embase, Scopus, International HTA database, the Centre for Reviews and Dissemination database and various HTA websites were searched (January 2005 to March 2021) to identify the eligible cost-effectiveness studies. PARTICIPANTS: Cost-effectiveness, cost-utility, or cost-minimization analyses examining RARP versus ORP or LRP were included in this systematic review. INTERVENTIONS: Different surgical approaches to treat localized prostate cancer: RARP compared with ORP and LRP. PRIMARY AND SECONDARY OUTCOME MEASURES: A structured narrative synthesis was developed to summarize results of cost, effectiveness, and cost-effectiveness results (eg, incremental cost-effectiveness ratio [ICER]). Study quality was assessed using the Consensus on Health Economic Criteria Extended checklist. Application of medical device features were evaluated. RESULTS: Twelve studies met inclusion criteria, 11 of which were cost-utility analyses. Higher quality-adjusted life-years and higher costs were observed with RARP compared with ORP or LRP in 11 studies (91%). Among four studies comparing RARP with LRP, three reported RARP was dominant or cost-effective. Among ten studies comparing RARP with ORP, RARP was more cost-effective in five, not cost-effective in two, and inconclusive in three studies. Studies with longer time horizons tended to report favorable cost-effectiveness results for RARP. Nine studies (75%) were rated of moderate or good quality. Recommended medical device features were addressed to varying degrees within the literature as follows: capital investment included in most studies, dynamic pricing considered in about half, and learning curve and incremental innovation were poorly addressed. CONCLUSIONS: Despite study heterogeneity, RARP was more costly and effective compared with ORP and LRP in most studies and likely to be more cost-effective, particularly over a multiple year or lifetime time horizon. Further cost-effectiveness analyses for RARP that more thoroughly consider medical device features and use an appropriate time horizon are needed. PROSPERO REGISTRATION NUMBER: CRD42021246811.

Rapid Histological Assessment of Prostate Specimens in the Three-dimensional Space by Hydrophilic Tissue Clearing and Confocal Microscopy.

Microscopic examination of biopsied and resected prostatic specimens is the mainstay in the diagnosis of prostate cancer. However, conventional analysis of hematoxylin and eosin (H&E)-stained tissue is time-consuming and offers limited two-dimensional (2D) information. In the current study, we devised a method-termed Prostate Rapid Optical examination for cancer STATus (proSTAT)-for rapid screening of prostate cancer using high-resolution 2D and three-dimensional (3D) confocal images obtained after hydrophilic tissue clearing of 100-µm-thick tissue slices. The results of the proSTAT method were compared with those of traditional H&E stains for the analysis of cores (n=15) obtained from radical prostatectomy specimens (n=5). Gland lumen formation, consistent with Gleason pattern 3, was evident following tracking of multiple optical imaging sections. In addition, 3D rendering allowed visualizing a tubular network of interconnecting branches. Rapid 3D fluorescent labeling of tumor protein p63 accurately distinguished prostate adenocarcinoma from normal tissue and benign lesions. Compared with conventional stains, the 3D spatial and molecular information extracted from proSTAT may significantly increase the amount of available data for pathological assessment of prostate specimens. Our approach is amenable to automation and-subject to independent validation-can find a wide spectrum of clinical and research applications.

Prostatic malakoplakia: clinicopathological assessment of a multi-institutional series of 49 patients.

Prostatic malakoplakia (MP) is rare, with only case reports and small series (< five patients) available in the literature. In this study we analysed an international multi-institutional series of 49 patients with prostatic MP to more clearly define its clinicopathological features. The median age was 67 years and the median serum prostate-specific antigen (PSA) was 7.5 ng/ml. MP was clinically manifest in most cases (28 of 45 patients with data available, 62%). Of 43 patients with detailed clinical history available, 21 (49%) had concurrent or metachronous malignancies (including prostate cancer). Diabetes or insulin resistance was present in 11 patients (26%). Additionally, three patients had a history of solid organ transplantation and one had HIV. Of note, six of 34 patients (18%) without concurrent prostate cancer had an abnormal digital rectal examination and/or lesions on magnetic resonance imaging (MRI) with prostate imaging reporting and data system (PIRADS) scores 4-5. The initial diagnosis was made on core biopsies (25 of 49, 51%), transurethal resection specimens (12 of 49, 24%), radical prostatectomies (10 of 49, 20%), Holmium-laser enucleation (one of 49, 2%) and cystoprostatectomy (one of 49, 2%). Tissue involvement was more commonly diffuse or multifocal (40 of 49, 82%). Von Kossa and periodic acid-Schiff stains were positive in 35 of 38 (92%) and 26 of 27 lesions (96%), respectively. Of note, two cases were received in consultation by the authors with a preliminary diagnosis of mesenchymal tumour/tumour of the specialised prostatic stroma. The present study suggests that prostatic MP is often associated with clinical findings that may mimic those of prostate cancer in a subset of patients. Moreover, MP may be found incidentally in patients with concurrent prostate cancer.

Comparison of the medical costs between active surveillance and other treatments for early prostate cancer in Japan using data from the PRIAS-JAPAN study.

OBJECTIVES: To compare the medical costs of active surveillance with those of robot-assisted laparoscopic prostatectomy, brachytherapy, intensity-modulated radiation therapy, and hormone therapy for low-risk prostate cancer. METHODS: The costs of protocol biopsies performed in the first year of surveillance (between January 2010 and June 2020) and those of brachytherapy and radiation therapy performed between May 2019 and June 2020 at the Kagawa University Hospital were analyzed. Hormone therapy costs were assumed to be the costs of luteinizing hormone-releasing hormone analogs for over 5 years. Active surveillance-eligible patients were defined based on the following: age <74 years, ≤T2, Gleason score ≤6, prostate-specific antigen level ≤10 ng/ml, and 1-2 positive cores. We estimated the total number of active surveillance-eligible patients in Japan based on the Japan Study Group of Prostate Cancer (J-CAP) study and the 2017 cancer statistical data. We then calculated the 5-year treatment costs of active surveillance-eligible patients using the J-CAP and PRIAS-JAPAN study data. RESULTS: In 2017, number of active surveillance-eligible patients in Japan was estimated to be 2808. The 5-year total costs of surveillance, prostatectomy, brachytherapy, radiation therapy, and hormone therapy were 1.65, 14.0, 4.61, 4.04, and 5.87 million United States dollar (USD), respectively. If 50% and 100% of the patients in each treatment group had opted for active surveillance as the initial treatment, the total treatment cost would have been reduced by USD 6.89 million (JPY 889 million) and USD 13.8 million (JPY 1.78 billion), respectively. CONCLUSION: Expanding active surveillance to eligible patients with prostate cancer helps save medical costs.

Impact of cribriform pattern 4 and intraductal prostatic carcinoma on National Comprehensive Cancer Network (NCCN) and Cancer of Prostate Risk Assessment (CAPRA) patient stratification.

Pretreatment classification tools are used in prostate cancer to inform patient management. The effect of cribriform pattern 4 (CC) and intraductal carcinoma (IDC) on such nomograms is still underexplored. We analyzed the Cancer of Prostate Risk Assessment (CAPRA) and National Comprehensive Cancer Network (NCCN) risk scores in cases with and without CC/IDC to assess impact on biochemical recurrence (BCR) and metastases/death of prostate cancer (event free survival-EFS) after prostatectomy. A matched biopsy- prostatectomy cohort (2010-2017) was reviewed for CC/IDC. CAPRA and NCCN scores were calculated. CAPRA score 0-2 were deemed "low", 3-5 "intermediate" and 6-10 "high". NCCN scores 1-2 "very low/low", 3 "favorable intermediate", 4 "unfavorable intermediate", 5-6 "high/very high". Cases were stratified by presence of CC/IDC. BCR and EFS probabilities were estimated using the Kaplan-Meier method. Prognostic performance was evaluated using log-rank tests and Harrell's concordance index. 612 patients with mean age 63.1 years were included with mean follow up of 5.3 (range 0-10.8) years. CC/IDC was noted in 159/612 (26%) biopsies. There were 101 (17%) BCR and 36 (6%) events. CAPRA discriminated three distinct risk categories for BCR (p < 0.001) while only high risk separated significantly for EFS (p < 0.001). NCCN distinguished two prognostic groups for BCR (p < 0.0001) and three for EFS (p < 0.0001). Addition of CC/IDC to CAPRA impacted scores 3-5 for BCR and scores 3-5 and 6-10 for EFS and improved the overall concordance index (BCR: 0.66 vs. 0.71; EFS: 0.74 vs. 0.80). Addition of CC/IDC to NCCN impacted scores 4 and 5-6 and also improved the concordance index for BCR (0.62 vs. 0.68). Regarding EFS, NCCN scores 4 and 5-6 demonstrated markedly different outcomes with the addition of CC/IDC. The CAPRA nomogram allows better outcome stratification than NCCN. Addition of CC/IDC status particularly improves patient stratification for CAPRA scores 3-5, 6-10, and for NCCN scores 4 and 5-6.

Frailty Assessment for Outcome Prediction of Patients With Prostate Cancer Receiving Radical Prostatectomy: A Meta-Analysis of Cohort Studies.

A meta-analysis was conducted to investigate the association between frailty and postoperative complications in patients with prostate cancer following radical prostatectomy. A systematic search of PubMed, Embase, and Web of Science was conducted for relevant cohort studies. A random-effect model was chosen to combine the results. Five cohort studies including 171,929 patients were included. Results showed that patients with frailty had higher risk of severe postoperative complications (Clavien-Dindo IV complications, risk ratio [RR]: 1.87, 95% confidence interval [CI]: 1.67 to 2.10, p < .001; I2 = 18%) and all-cause mortality (RR: 2.89, 95% CI: 1.86 to 4.50, p < 0.001; I2 = 18%). Subgroup analyses showed consistent results in patients receiving open and robot-assisted radical prostatectomy, and also in studies with univariate and multivariate analyses. In conclusion, preoperative frailty may be a predictor of severe postoperative complications and all-cause mortality of patients with prostate cancer following radical prostatectomy.

Geographic Variability, Time Trends and Association of Preoperative Magnetic Resonance Imaging with Surgical Outcomes for Elderly United States Men with Prostate Cancer: A Surveillance, Epidemiology, and End Results-Medicare Analysis.

PURPOSE: Our goal was to assess patterns of adoption and population-level outcomes of prostate magnetic resonance imaging (MRI) and association with surgical outcomes across a sample of U.S. elderly. MATERIALS AND METHODS: This population-based retrospective study used Surveillance Epidemiology, and End Results-Medicare linked data from 2003-2016 to identify men receiving prostatectomy for prostate cancer. We characterized the proportion of men receiving preoperative MRI in each year and in each hospital referral region (HRR). A 2-stage instrumental variable analysis was performed to assess the association of preoperative MRI with margin status, surgical complications and further cancer-directed therapies. RESULTS: A total of 19,369 men received prostatectomy in 72 HRRs; the mean age was 70.2 years (SD 3.2). The proportion of men receiving a preoperative MRI increased from 2.9% to 28.2% over the study period and ranged from 0.0% to 28.8% in the different HRRs. In our instrumental variable analysis, preoperative MRI was associated with lower odds of positive surgical margin (OR 0.84, 95% CI 0.72-0.97, p=0.01) lower odds of blood transfusions at 30 and 90 days (OR 0.56, 95% CI 0.38-0.83, p=0.003 and OR 0.58, 95% CI 0.41-0.84, p=0.004) but higher odds of further treatments (OR 1.49, 95% CI 1.32-1.70, p <0.001). CONCLUSIONS: Given that a minority of men receive presurgical MRIs with marked geographic variability, the association of MRI with lower odds of positive surgical margin suggests that efforts to support the dissemination of prostate MRI may improve surgical outcomes-but may come with a tendency for more resource-intensive cancer care overall.

Cost-utility analysis on robot-assisted and laparoscopic prostatectomy based on long-term functional outcomes.

Robot-Assisted Radical Prostatectomy (RARP) is one of the standard treatment options for prostate cancer. However, controversy still exists on its added value. Based on a recent large-sample retrospective cluster study from the Netherlands showing significantly improved long-term urinary functioning after RARP compared to Laparoscopic RP (LRP), we evaluated the cost-effectiveness of RARP compared to LRP. A decision tree was constructed to measure the costs and effects from a Dutch societal perspective over a ~ 7 year time-horizon. The input was based on the aforementioned study, including patient-reported consumption of addition care and consumed care for ergonomic issues reported by surgeons. Intervention costs were calculated using a bottom-up costing analysis in 5 hospitals. Finally, a probabilistic-, one-way sensitivity- and scenario analyses were performed to show possible decision uncertainty. The intervention costs were €9964 for RARP and €7253 for LRP. Total trajectory costs were €12,078 for RARP and €10,049 for LRP. RARP showed higher QALYs compared to LRP (6.17 vs 6.11). The incremental cost-utility ratio (ICUR) was €34,206 per QALY gained, in favour of RARP. As a best-case scenario, when RARP is being centralized (> 150 cases/year), total trajectory costs decreased to €10,377 having a higher utilization, and a shorter procedure time and length of stay resulting in an ICUR of €3495 per QALY gained. RARP showed to be cost-effective compared to LRP based on data from a population-based, large scale study with 7 years of follow-up. This is a clear incentive to fully reimburse RARP, especially when hospitals provide RARP centralized.

Cost-effectiveness of Robotic-Assisted Radical Prostatectomy for Localized Prostate Cancer in the UK.

Importance: The cost-effectiveness of different surgical techniques for radical prostatectomy remains a subject of debate. Emergence of recent critical clinical data and changes in surgical equipment costs due to their shared use by different clinical specialties necessitate an updated cost-effectiveness analysis in a centralized, largely government-funded health care system such as the UK National Health Service (NHS). Objective: To compare robotic-assisted radical prostatectomy (RARP) with open radical prostatectomy (ORP) and laparoscopic-assisted radical prostatectomy (LRP) using contemporary data on clinical outcomes, costs, and surgical volumes in the UK. Design, Setting, and Participants: This economic analysis used a Markov model developed to compare the cost-effectiveness of RARP, LRP, and ORP to treat localized prostate cancer. The model was constructed from the perspective of the UK NHS. The model simulated 65-year-old men who underwent radical prostatectomy for localized prostate cancer and were followed up for a 10-year period. Data were analyzed from May 1, 2020, to July 31, 2021. Exposures: Robotic-assisted radical prostatectomy, LRP, and ORP. Main Outcomes and Measures: Quality-adjusted life-years (QALYs), costs (direct medical costs and costs outside the NHS), and incremental cost-effectiveness ratios (ICERs). Results: Compared with LRP, RARP cost £1785 (US $2350) less and had 0.24 more QALYs gained; thus, RARP was a dominant option compared with LRP. Compared with ORP, RARP had 0.12 more QALYs gained but cost £526 (US $693) more during the 10-year time frame, resulting in an ICER of £4293 (US $5653)/QALY. Because the ICER was below the £30 000 (US $39 503) willingness-to-pay threshold, RARP was more cost-effective than ORP in the UK. The most sensitive variable influencing the cost-effectiveness of RARP was the lower risk of biochemical recurrence (BCR). Scenario analysis indicated RARP would remain more cost-effective than ORP as long as the BCR hazard ratios comparing RARP vs ORP were less than 0.99. Conclusions and Relevance: These findings suggest that in the UK, RARP has an ICER lower than the willingness-to-pay threshold and thus is likely a cost-effective surgical treatment option for patients with localized prostate cancer compared with ORP and LRP. The results were mainly driven by the lower risk of BCR for RARP. These findings may differ in other health care settings where different thresholds and costs may apply.

Assessment after focal therapy: what is the latest?

PURPOSE OF REVIEW: To review assessment after focal therapy (FT) in the context of developments from the past two years. RECENT FINDINGS: With a paucity of high-quality studies, recent findings are primarily reliant on results from institutional-based cohorts and reports of expert consensus. Notably, oncologic treatment failure should be further stratified into recurrence in the in-field or out-of-field ablation zone, and both regions should be surveilled postoperatively. Monitoring primarily consists of periodic evaluations of prostate-specific antigen (PSA) testing and magnetic resonance imaging, with histologic sampling needed to confirm suspicion of recurrence. Recent investigations into PSA derivatives, contrast-enhanced ultrasound, and prostate-specific membrane antigen imaging have shown preliminary promise. Although postablation functional outcomes are generally accepted to be excellent, they are limited by the wide range of patient-reported measures, variability in individual practice, and low questionnaire completion rates. SUMMARY: There is still a need for high-level, long-term data to inform exact standardized protocols to manage patients after FT. A multifaceted approach is required to surveil patients and identify those at risk of recurrence. Embracing shared responsibility between the patient and clinician to fastidiously monitor the infield and out-of-field ablation zones postoperatively is critical to maximize oncologic outcomes.

[Assessment of positive surgical margins in the management of patients after radical prostatectomy for pT2 prostate cancer]. / Impact des marges chirurgicales positives après prostatectomie radicale chez les patients atteints d'un cancer de la prostate localisé pT2.

INTRODUCTION: Few data are available regarding positive surgical margins (PSM) in patients who underwent surgery for localized prostate cancer (PC). Our objective was to evaluate the impact of PSM on biochemical recurrence-free survival (BRFS) for patients who underwent PC for pT2 tumor without adjuvant treatment. METHODS: We included each patient who underwent radical prostatectomy for pT2N0 PC between 1988 and 2018. Primary endpoint was biochemical recurrence (BR). BRFS was calculated using Kaplan-Meier method. Univariate and multivariate analyses were used to determine factors associated with BR and PSM. RESULTS: Overall, 2429 patients were included whom 420 patients had PSM (17.3%). Median follow-up was 116 months. BRFS at 10 years was 66.6% in case of PSM, and 84% in the negative margins group (P<0.0001). Parameters associated with BR were preoperative PSA level (P<0.0001), Gleason score (P<0.0001), tumor volume in biopsies, and margins length (P<0.04). CONCLUSION: PSM in pT2N0 CP are associated with poor prognosis in terms of BR. Nevertheless, only a small number of pT2R1 cancer will present biological recurrence. The use of adjuvant radiotherapy in these patients therefore represents a risk of overtreatment, with the risk of adverse effects inherent to irradiation. Clinical and biological monitoring in case of PSM seems acceptable.

Preoperative nutritional evaluation of prostate cancer patients undergoing laparoscopic radical prostatectomy.

BACKGROUND AND OBJECTIVE: Prostate cancer (PCa) is one of the most common malignant tumors in men. Geriatric Nutritional Risk Index (GNRI) is an objective index for evaluating nutritional status of elderly people over 65 years old. The aim of the current study was to explore the correlation and predictive value between GNRI and postoperative recovery and complications in PCa patients undergoing laparoscopic radical prostatectomy (LRP). METHODS: Taking 98 as the GNRI boundary value, 96 PCa patients (aged≥65 y) undergoing LRP in the Department of Urology, Affiliated Hospital of North Sichuan Medical College from January 2018 to December 2020 were grouped into malnutrition group (MNg, 34 patients, 35.4%) and normal nutrition group (NNg, 62 patients, 64.6%). Basic information, laboratory examination indexes, operation conditions, postoperative complications and postoperative recovery indexes of patients were recorded and retrospectively analyzed. Clavien-Dindo Classification System (CDCS) was used to assess postoperative complications. T-test was used to analyze differences between the two groups. ROC curve was generated to determine the predictive value of GNRI for postoperative complications. RESULTS: Percentage of complications was significantly higher in MNg group compared with that in NNg group (P < 0.01). The average grade based on CDCS was significantly lower in NNg group compared with that in MNg group (P < 0.01). Body weight, Body Mass Index (BMI), preoperative hemoglobin value (HGB), serum albumin (ALB) values of MNg and NNg were significantly positively correlated with GNRI (P<0.01). Incidence and severity of postoperative complications of MNg patients were significantly higher compared with those of NNg patients (P<0.05). Average hospitalization cost of MNg patients was higher in MNg patients compared with that of NNg patients (P<0.05). Duration of post-anesthesia care unit (PACU), duration of antibiotic use and duration of indwelling drainage tube were longer in MNg patients compared with those in NNg patients (P<0.05). Furthermore, volume of indwelling drainage tube was higher in MNg patients compared with that in NNg patients (P<0.05). CONCLUSION: GNRI is an effective and reliable tool for evaluation of preoperative nutritional status of prostate cancer patients. The findings showed that GNRI is correlated with postoperative recovery and complications, and is an effective predictive marker.

Self-reported functional assessment after treatment for prostate cancer: 5-year results of the prospective cohort VICAN.

Objective: We aimed to assess the long-term association of therapeutic strategies with urinary, sexual function and health-related quality of life (HR-QoL) for 5-year prostate cancer (PC) survivors. Materials & methods: The VICAN survey consisted of self-reported data prospectively collected, including living conditions, treatment side effects and quality of life (QoL) of cancer survivors. Results: Among the 434 PC survivors, 52.8% reported urinary incontinence (UI) and 55.8% reported erectile dysfunction (ED). Patients treated with radical prostatectomy with salvage radiotherapy reported significantly more UI (p = 0.014) and more ED (p = 0.012) compared with other strategies. UI was significantly associated with physical and mental health-related QoL (p = 0.045 and p = 0.049, respectively). Conclusion: Self-assessed functional outcomes 5 years after PC diagnosis remain poor and could have an impact on health-related QoL.

Patients treated for prostate cancer may have long-term consequences due to the treatment they receive ­ in particular urinary incontinence (UI) and erectile dysfunction (ED). We analyzed self-reported data from 434 patients diagnosed with prostate cancer 5 years earlier, focusing especially on treatment side effects and the impact on patient quality of life. Of these patients, 52.8% reported UI and 55.8% reported ED. Patients treated with surgery plus radiotherapy reported significantly more UI and more ED compared with other treatment strategies. We have also shown that UI has an impact on physical and mental quality of life of these patients. In conclusion, functional recovery 5 years after prostate cancer diagnosis remains poor and requires implementation of new, long-term management strategies for cancer survivors.

Male sling placement for post-prostatectomy incontinence can involve a lengthy learning curve: A multi-outcome assessment via cumulative sum failure analysis.

PURPOSES: Little research exists on potential learning curve for male sling procedures. We aimed to perform a learning curve analysis of a single surgeon's experience of sling placement evaluating multiple outcomes and using the cumulative sum failure methodology. METHODS: The study included 65 consecutive patients that underwent implantation of a fixed transobturator sling (TiLOOP Male) for post-radical prostatectomy stress incontinence at our institution from January 2013 to December 2018. Dichotomous outcomes evaluated with cumulative sum failure analysis included 12-months continence defined based on Patient Global Impression of Improvement (PGI-I) questionnaire (primary outcome), 24 h pad test and, 24 h pad use, operative time (⩽/>60 min), and complications (yes/no). Univariate and multivariate logistic regression analyses were performed to evaluate the association of the procedures' chronological sequence number with the outcomes. RESULTS: Cumulative sum failure curves revealed a clear and lengthy learning curve effect for most of subjective and quantitative continence outcomes and for operative time. For the primary outcome (at least much improved at PGI-I), 62 procedures were required to overcome the learning curve. Accordingly, multivariate analyses showed that the sequence number was statistically significant for predicting failures based on PGI-I (adjusted OR 0.95; 95% CI: 0.91-0.99; p = 0.02), objective outcomes, and operative time. CONCLUSIONS: An evident and lengthy learning curve was observed in our series of male sling placement to achieve the end level of proficiency, independently from case-mix. Individualized structured training on male sling surgery will benefit patients treated in the initial surgeon's experience. Surgical experience should be considered when reporting studies on male slings.

Does type of robotic platform make a difference in the final cost of robotic-assisted radical prostatectomy?

This study evaluates the difference of robot-assisted radical prostatectomy (RARP) costs in patients with similar preoperative characteristics operated on using the da Vinci® SP and Xi robotic platforms. We performed a retrospective analysis on 71 consecutive patients with prostate cancer who underwent RARP with the SP robot between June 2019 and April 2020. Propensity score (PS) matching was performed and 71 patients were selected from a cohort of 875 who underwent RARP with the Xi robot in the same period. We divided the total expense per surgery into the cost of disposable materials, robotic instruments (initial purchasing cost divided by the number of "lives"), and operative room costs. Only variable costs are included in this study, as fixed costs do not vary between procedures and are the same for both cohorts. Fixed costs include anesthesia, pathology, surgeon, and hospitalization fees. The median total cost for SP-RARP was $5586 ($5360-$5982) USD and $4875 ($4661-$5093) USD with the XI for a median cost difference of $707 ($584-$832) (P < 0.001). The median cost of disposables for the SP was $1877 ($1588-$2193) USD and for the Xi $1527 ($1407-$1781) USD, P < 0.001. Non-disposable instruments cost per case (fixed cost) was $1610 and $1270 USD for the SP and Xi, respectively. The cost of radical prostatectomy in the SP cohort is higher than the Xi cohort. The greater price was primarily due to the increased cost of instruments and disposable materials. In our experience, the lack of GelPOINT and space maker is also crucial factors to decrease the SP total cost.

Management of Patients Receiving Direct Oral Anticoagulants Scheduled for Radical Prostatectomy: An Update of a Prospective Assessment.

BACKGROUND: In the perioperative setting, temporary interruption of direct oral anticoagulants (DOACs) is mandatory. However, the safety of these recommendations is largely based on nonurological surgical experiences. OBJECTIVE: To verify the safety of these recommendations in patients undergoing radical prostatectomy (RP). DESIGN, SETTING, AND PARTICIPANTS: A total of 5317 patients underwent RP in our tertiary care centre between December 2017 and February 2020. Of them, 107 consecutive patients had DOACs in standard preoperative medication. DOAC intake was stopped 2-3 d before RP. Postoperatively, patients received weight- and risk-adapted low-molecular-weight heparin (LMWH). DOAC intake was restarted, and administration of LMWH was stopped the 3rd day after surgery. For comparison, we performed 1:2 propensity-score matching (DOAC:non-DOAC), which resulted in 321 consecutive patients. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Perioperative outcomes and 30-d morbidity were compared between both cohorts. The Wilcoxon rank sum test and the Pearson's chi-square test were used. RESULTS AND LIMITATIONS: The median age of patients with DOACs was 68 yr. Sixty-six patients (61.7%) stopped DOAC intake 48 h and 41 patients (38.3%) 72 h before RP. In comparison with the matching cohort, the median blood loss during RP, median duration of surgery, and median duration of hospitalisation did not differ in a statistically significant fashion. Similarly, there was no significant difference in 30-d morbidity between groups. Importantly, the rate of bleeding and thromboembolic complications did likewise not differ significantly, though it is a nonrandomised and retrospective study. CONCLUSIONS: Standardised perioperative management of DOACs is important to minimise bleeding and thromboembolic complications. RP can be performed with a low perioperative complication risk if patients are adherent to our presented algorithm. PATIENT SUMMARY: We looked at peri- and postoperative complications and compared direct oral anticoagulant (DOAC) and non-DOAC patients. We found no significant difference in thromboembolic and bleeding complications between the groups. We conclude that our regime is safe.

A Comprehensive Assessment of 68Ga-PSMA-11 PET in Biochemically Recurrent Prostate Cancer: Results from a Prospective Multicenter Study on 2,005 Patients.

We prospectively investigated the performance of the prostate-specific membrane antigen (PSMA) ligand 68Ga-PSMA-11 for detecting prostate adenocarcinoma in patients with elevated levels of prostate-specific antigen (PSA) after initial therapy. Methods:68Ga-PSMA-11 hybrid PET was performed on 2,005 patients at the time of biochemically recurrent prostate cancer after radical prostatectomy (RP) (50.8%), definitive radiation therapy (RT) (19.7%), or RP with postoperative RT (PORT) (29.6%). The presence of prostate cancer was assessed qualitatively (detection rate = positivity rate) and quantitatively on a per-patient and per-region basis, creating a disease burden estimate from the presence or absence of local (prostate/prostate bed), nodal (N1: pelvis), and distant metastatic (M1: distant soft tissue and bone) disease. The primary study endpoint was the positive predictive value (PPV) of 68Ga-PSMA-11 PET/CT confirmed by histopathology. Results: After RP, the scan detection rate increased significantly with rising PSA level (44.8% at PSA < 0.25%-96.2% at PSA > 10 ng/mL; P < 0.001). The detection rate significantly increased with rising PSA level in each individual region, overall disease burden, prior androgen deprivation, clinical T-stage, and Gleason grading from the RP specimen (P < 0.001). After RT, the detection rate for in-gland prostate recurrence was 64.0%, compared with 20.6% prostate bed recurrence after RP and 13.3% after PORT. PSMA-positive pelvic nodal disease was detected in 42.7% after RP, 40.8% after PORT, and 38.8% after RT. In patients with histopathologic validation, the PPV per patient was 0.82 (146/179). The SUVmax of histologically proven true-positive lesions was significantly higher than that of false-positive lesions (median, 11.0 [interquartile range, 6.3-22.2] vs. 5.1 [interquartile range, 2.2-7.4]; P < 0.001). Conclusion: We confirmed a high PPV for 68Ga-PSMA-11 PET in biochemical recurrence and the PSA level as the main predictor of scan positivity.
