RESUMO
INTRODUCTION: Leukemia history affects some radical prostatectomy (RP) patients. Although its prevalence and effect as an adverse risk factor are well known in cardiac surgery, the number of RP patients with a leukemia history, as well as their rate of adverse in-hospital outcomes, are unknown. METHODS: We identified RP patients (National Inpatient Sample 2000-2019), stratified according to the presence or absence of a leukemia history. Descriptive analyses, propensity score matching (PSM, ratio 1:10), and multivariable logistic regression models were used. RESULTS: Of 259,939 RP patients, 416 (0.2%) had a leukemia history. Their proportion increased from 0.1 to 0.2% covering the study span (p < 0.01). Leukemia history patients were older (median age, 64 vs. 62 years, p < 0.001). After PSM for age, insurance status, ethnicity, pelvic lymph node dissection, and Charlson Comorbidity Index, leukemia history RP patients exhibited higher rates of acute kidney injury (<2.6 vs. 0.9%; Odds Ratio [OR] 2.0, p = 0.02), more frequently underwent dialysis (3.6 vs. 1.9%; OR 1.9, p = 0.03), and more frequently had a length of stay exceeding one week (4.8 vs. 2.5%; OR 2.0, p = 0.006). CONCLUSIONS: Although leukemia history RP patients are rare, their numbers have increased. Renal complications and extended hospital stays are more frequent in those individuals.
RESUMO
BACKGROUND: Historical external beam radiation therapy (EBRT) for rectosigmoid cancer (RCa) predisposed patients to an increased risk of secondary bladder cancer (BCa). However, no contemporary radiotherapy studies are available. We addressed this knowledge gap. MATERIALS AND METHODS: Within the Surveillance, Epidemiology, and End Results database (2000-2020), we identified non-metastatic RCa patients who either underwent radiotherapy (EBRT+) or did not (EBRT-). Cumulative incidence plots and multivariable competing risk regression models (CRR) were fitted to address rates of BCa after RCa. In the subgroup of BCa patients, the same methodology addressed BCa-specific mortality (BCSM) according to EBRT exposure status. RESULTS: Of the 188,658 non-metastatic RCa patients, 54,562 (29%) were EBRT+ vs. 134,096 (73%) who were EBRT-. In the cumulative incidence plots, the ten-year BCa rates were 0.7% in EBRT+ vs. 0.7% in EBRT- patients (p = 0.8). In the CRR, EBRT+ status was unrelated to BCa rates (multivariable HR: 1.1, p = 0.8). In the subgroup of 1416 patients with BCa after RCa, 443 (31%) were EBRT+ vs. 973 (69%) who were EBRT-. In the cumulative incidence plots, the ten-year BCSM rates were 10.6% in EBRT+ vs. 12.1% in EBRT- patients (p = 0.7). In the CRR, EBRT+ status was unrelated to subsequent BCSM rates (multivariable HR: 0.9, p = 0.9). CONCLUSION: Although historical EBRT for RCa predisposed patients to higher BCa rates, contemporary EBRT for RCa is not associated with increased subsequent BCa risk. Moreover, in patients with BCa after RCa, exposure to EBRT does not affect BCSM.
RESUMO
BACKGROUND: Induction followed by 1 year maintenance instillation of intravesical Bacillus Calmette-Guerin (BCG) is the standard treatment for intermediate-risk (IR) nonmuscle invasive bladder cancer (NMIBC) patients. Few data exist on the efficacy of Mitomycin C (MMC) instillation in this setting. METHODS: We retrospectively analyzed 226 IR-NMIBC patients classified by the International Bladder Cancer Group (IBCG) and 250 IR-NMIBC intravescical treatment-naïve patients classified by the European Association of Urology (EAU). All patients received either a full induction course of BCG or 40 mg/40 ml MMC from 2012 to 2022. Optimal treatment was defined as 1-year maintenance for BCG and 11 monthly maintenance instillations for MMC. Kaplan-Meier analysis estimated recurrence-free survival (RFS) before and after inverse probability of treatment-weighting (IPTW) and progression-free survival (PFS). Multivariable Cox regression was used to evaluate difference in recurrence after adjustment for clinically relevant variables before and after IPTW. RESULTS: Optimal BCG and MMC courses were administered to 21% of IR-IBCG and 23% of IR-EAU patients. At 4-years, patients treated with optimal MMC and BCG treatment had similar RFS and PFS in both EAU and IBCG groups. Patients receiving nonoptimal BCG compared to optimal MMC exhibited lower 4-year RFS after IPTW (82% vs. 68% in EAU and 82% vs. 65% in IBCG). At 4-year optimal MMC had greater PFS non optimal BCG. Optimal MMC treatment predicted recurrence in EAU (adjusted and weighted HR 0.33, 95% CI, 0.11-0.98) and IBCG (adjusted and weighted HR 0.29, 95% CI, 0.08-0.97) groups compared to nonoptimal BCG. CONCLUSIONS: Optimal 40 mg/40 ml MMC treatment was as effective as optimal BCG in IR-IBCG and IR-EAU NMIBC patients, reducing both recurrence and progression compared to nonoptimal BCG. MMC could be a valid first line alternative to BCG for both IR-EAU and IR-IBCG intravescical treatment-naïve patients, during BCG shortages.
RESUMO
OBJECTIVE: To assess the diagnostic performance of 18F-fluoro-2-deoxy-d-glucose (18F-FDG) positron emission tomograpy (PET)/computed tomography (CT) in nodal staging before radical cystectomy (RC) and pelvic lymph node dissection (PLND) for bladder cancer (BCa). MATERIALS AND METHODS: This analysis was based on a cohort of 199 BCa patients undergoing RC and bilateral PLND between 2015 and 2022. Neoadjuvant chemotherapy (NAC) or immunotherapy (NAI) was administered after oncological evaluation. All patients received preoperative 18F-FDG PET/CT to assess extravesical disease. Point estimates for true negative, false negative, false positive, true positive, sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy of conventional imaging and PET/CT were calculated. Subgroup analysis in patients receiving neoadjuvant treatment was performed. RESULTS: At preoperative evaluation, 30 patients (15.1%) had 48 suspicious nodal spots on 18F-FDG PET/CT. At RC and bilateral PLND, a total of 4871 lymph nodes (LNs) were removed with 237 node metastases corresponding to 126 different regions. Pathological node metastases were found in 17/30 (57%) vs 39/169 patients (23%) with suspicious vs negative preoperative 18F-FDG PET/CT, respectively (sensitivity = 0.30, specificity = 0.91, PPV = 0.57, NPV = 0.77, accuracy = 0.74). On per-region analysis including 1367 nodal regions, LN involvement was found in 19/48 (39%) vs 105/1319 (8%) suspicious vs negative regions at PET/CT, respectively (sensitivity = 0.15, specificity = 0.98, PPV = 0.40, NPV = 0.92, ACC = 0.90). Similar results were observed for patients receiving NAC (n = 44, 32.1%) and NAI (n = 93, 67.9% [per-patient: sensitivity = 0.36, specificity = 0.91, PPV = 0.59, NPV = 0.80, accuracy = 0.77; per-region: sensitivity = 0.12, specificity = 0.98, PPV = 0.32, NPV = 0.93, ACC = 0.91]). Study limitations include its retrospective design and limited patient numbers. CONCLUSIONS: In eight out of 10 patients with negative preoperative 18F-FDG PET/CT, pN0 disease was confirmed at final pathology. No differences were found based on NAC vs NAI treatment. These findings suggest that 18F-FDG PET/CT could play a role in the preoperative evaluation of nodal metastases in BCa patients, although its cost-effectiveness is uncertain.
RESUMO
PURPOSE: No studies relied on a standardized methodology to collect postoperative complications after robot-assisted radical cystectomy (RARC). The aim of our study was to evaluate peri- and post-operative outcomes of patients undergoing RARC adhering to the European Association of Urology (EAU) recommendations for reporting surgical outcomes and using a long postoperative follow-up. MATERIALS AND METHODS: 246 patients who underwent RARC with intracorporal urinary diversion at a single tertiary referral center with a postoperative follow-up ≥ 1 year for survivors. Postoperative outcomes were collected prospectively by interviews done by medical doctors. Complications were scored using the Clavien-Dindo classification (CD), grouped by type and severity (severe: CD score ≥ 3). We described peri- and post-operative outcomes and complication chronological distribution. RESULTS: Overall, 16 (6.5%) and 225 patients (91%) experienced intraoperative and postoperative complications, respectively. Moreover, 139 (57%) experienced severe complications. The most common any-grade and severe complications were infectious (72%) and genitourinary (35%), respectively. Overall, 52% of complications (358/682) occurred within 10 days from surgery, and 51% of severe complications (106/207) occurred within 35 days. However, 13% of complications (90/682) and 28% of severe complications (59/207) occurred 3 months after surgery. The earliest complications were fever of unknown origins and paralytic ileus (median time-to-complication [mTTC]: 4 days), the latest complications were urinary tract infection (mTTC: 40 days) and hydronephrosis/ureteral obstruction (mTTC: 70 days). CONCLUSIONS: The rate of postoperative complications after RARC is > 90% when a standardized collection method and a long follow-up is implemented. These results should be used to identify potential areas of improvement and for preoperative patient counseling.

BACKGROUND: To date, the benefit of image guidance during robot-assisted surgery (IGS) is an object of debate. The current study aims to address the quality of the contemporary body of literature concerning IGS in robotic surgery throughout different surgical specialties. METHODS: A systematic review of all English-language articles on IGS, from January 2013 to March 2023, was conducted using PubMed, Cochrane library's Central, EMBASE, MEDLINE, and Scopus databases. Comparative studies that tested performance of IGS vs control were included for the quantitative synthesis, which addressed outcomes analyzed in at least three studies: operative time, length of stay, blood loss, surgical margins, complications, number of nodal retrievals, metastatic nodes, ischemia time, and renal function loss. Bias-corrected ratio of means (ROM) and bias-corrected odds ratio (OR) compared continuous and dichotomous variables, respectively. Subgroup analyses according to guidance type (i.e., 3D virtual reality vs ultrasound vs near-infrared fluoresce) were performed. RESULTS: Twenty-nine studies, based on 11 surgical procedures of three specialties (general surgery, gynecology, urology), were included in the quantitative synthesis. IGS was associated with 12% reduction in length of stay (ROM 0.88; p = 0.03) and 13% reduction in blood loss (ROM 0.87; p = 0.03) but did not affect operative time (ROM 1.00; p = 0.9), or complications (OR 0.93; p = 0.4). IGS was associated with an estimated 44% increase in mean number of removed nodes (ROM 1.44; p < 0.001), and a significantly higher rate of metastatic nodal disease (OR 1.82; p < 0.001), as well as a significantly lower rate of positive surgical margins (OR 0.62; p < 0.001). In nephron sparing surgery, IGS significantly decreased renal function loss (ROM 0.37; p = 0.002). CONCLUSIONS: Robot-assisted surgery benefits from image guidance, especially in terms of pathologic outcomes, namely higher detection of metastatic nodes and lower surgical margins. Moreover, IGS enhances renal function preservation and lowers surgical blood loss.

OBJECTIVE: To determine the oncological impact of extended pelvic lymph node dissection (ePLND) vs standard PLND (sPLND) during radical cystectomy (RC) in clinically lymph node-positive (cN+) bladder cancer (BCa). PATIENTS AND METHODS: In this retrospective, multicentre study we included 969 patients who underwent RC with sPLND (internal/external iliac and obturator lymph nodes) or ePLND (sPLND plus common iliac and presacral nodes) with or without platin-based peri-operative chemotherapy for cTany N1-3 M0 BCa between 1991 and 2022. We assessed the impact of ePLND on recurrence-free survival (RFS) and the distribution of recurrences (locoregional and distant recurrences). The secondary endpoint was overall survival (OS). We performed propensity-score matching using covariates associated with the extent of PLND in univariable logistic regression analysis. The association of the extent of PLND with RFS and OS was investigated using Cox regression models. RESULTS: Of 969 cN+ patients, 510 were 1:1 matched on propensity scores. The median (interquartile range [IQR]) time to recurrence was 8 (4-16) months, and median (IQR) follow-up of alive patients was 30 (13-51) months. Disease recurrence was observed in 104 patients in the ePLND and 107 in the sPLND group. Of these, 136 (27%), 47 (9.2%) and 19 patients (3.7%) experienced distant, locoregional, or both distant and locoregional disease recurrence, respectively. When stratified by the extent of PLND, we did not find a difference in recurrence patterns (P > 0.05). ePLND improved neither RFS (hazard ratio [HR] 0.91, 95% confidence interval [CI] 0.70-1.19; P = 0.5) nor OS (HR 0.78, 95% CI 0.60-1.01; P = 0.06) compared to sPLND. Stratification by induction chemotherapy did not change outcomes. CONCLUSION: Performing an ePLND at the time of RC in cN+ patients improved neither RFS nor OS compared to sPLND, regardless of induction chemotherapy status. Pretreatment risk stratification is paramount to identify ideal candidates for RC with ePLND as part of a multimodal treatment approach.

INTRODUCTION: Lymph node (LN) involvement is a crucial determinant of prognosis for patients with bladder cancer, and an accurate staging is of utmost importance to better identify timely and appropriate therapeutic strategies. To improve the accuracy of LN detection, as an alternative to traditional methods such as CT or MRI, 18F-FDG PET/CT has been increasingly used. 18F-FDG PET/CT is also used in post-treatment restaging after neoadjuvant chemotherapy. The aim of this narrative literature review is to provide an overview of the current evidence on the use of 18F-FDG PET/CT in the diagnosis, staging, and restaging of bladder cancer, with a particular focus on its sensitivity and specificity for the detection of LN metastasis. We aim to provide clinicians with a better understanding of 18F-FDG PET/CT's potential benefits and limitations in clinical practice. MATERIALS AND METHODS: We designed a narrative review starting from a wide search in the PubMed/MEDLINE and Embase databases, selecting full-text English articles that have examined the sensibility and specificity of PET/CT for nodal staging or restaging after neoadjuvant therapy in patients with bladder cancer. The extracted data were analyzed and synthesized using a narrative synthesis approach. The results are presented in a tabular format, with a summary of the main findings of each study. RESULTS: Twenty-three studies met the inclusion criteria: fourteen studies evaluated 18F-FDG PET/CT for nodal staging, six studies examined its accuracy for restaging after neoadjuvant therapy, and three studies evaluated both applications. To date, the use of F-18 FDG PET/TC for detection of LN metastasis in bladder cancer is controversial and uncertain: some studies showed low accuracy rates, but over the years other studies have reported evidence of high sensitivity and specificity. CONCLUSIONS: 18F-FDG PET/CT provides important incremental staging and restaging information that can potentially influence clinical management in MIBC patients. Standardization and development of a scoring system are necessary for its wider adoption. Well-designed randomized controlled trials in larger populations are necessary to provide consistent recommendations and consolidate the role of 18F-FDG PET/CT in the management of bladder cancer patients.
RESUMO
INTRODUCTION: Erectile dysfunction (ED) affects between 12.9% and 28.1% of men worldwide, presenting a strong aged-correlated prevalence. Several pharmacological treatments are currently available for ED, which can be classified into oral, injection, and topical/intraurethral therapies. AREAS COVERED: Extensive research on PubMed/MEDLINE until February 2023 was performed. For each of the aforementioned drug classes, available molecules, and formulations, their efficacy and most common adverse events as well as general guidelines on prescription were investigated and extensively described. A glimpse into future directions regarding ED pharmacotherapy is also present. EXPERT OPINION: In recent years, there have been significant developments in pharmacological treatments for ED. It is essential for physicians to identify the best treatment option for patients based on their preferences and sexual habits. The treatment approach for ED has shifted from a sequential to a parallel paradigm, where all treatment options are available as first-line therapies. While there are promising regenerative therapies for ED, such as shockwaves and platelet-rich plasma injections, pharmacological treatment is still the most effective option for most patients.

BACKGROUND: Holmium laser enucleation of the prostate (HoLEP) is considered a challenging procedure even for surgeons who have completed the learning curve. OBJECTIVES: To assess outcomes and complications following HoLEP performed by a highly experienced surgeon. DESIGN, SETTING, AND PARTICIPANTS: This was a single-institution prospective study (NCT03583034) performed at a tertiary referral centre that included 243 consecutive patients with lower urinary tract symptoms (LUTS) due to benign prostatic enlargement (BPE) treated with HoLEP by a single experienced surgeon (>1600 cases). OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Patients were assessed using validated questionnaires and uroflowmetry at baseline and several follow-up dates. Intraoperative and postoperative complications were recorded. Kaplan-Meier analysis was used to estimate recovery rates for urinary continence and erectile function. Logistic regression models were constructed to assess predictors of postoperative complications. RESULTS AND LIMITATIONS: Of the 243 patients, 78 (32.1%) had an indwelling urethral catheter. The median prostate volume (PV) was 87 cm3 (interquartile range 60-115) and 146 patients (59.8%) had PV >80 cm3. At 3-mo follow-up, 219 patients (90.1%) had a peak flow rate >20 ml/s and 182 (74.9%) had no postvoid residual urine. The improvement in subjective symptoms was significant at 1-mo follow-up and was maintained until 12 mo after surgery. Urinary continence recovery was slow, with an estimated rate of 68% (95% confidence interval [CI] 62-74%) at 1 mo and 94% (95% CI 91-97%) at 12 mo after HoLEP. The recovery rate for erectile function was 53% (95% CI 46-61%) at 1 mo and 85% (95% CI 77-90%) at 12 mo. Postoperative complications occurred in 36 patients (14.8%) during their hospital stay, in 34 (14%) within 1 mo following discharge from hospital, and in ten (4.1%) at later follow-up dates. Clinically significant complications (Clavien-Dindo ≥2) were observed in 44 cases (18%) and were more common for patients with an indwelling catheter at baseline (odds ratio 5.05; p = 0.006). CONCLUSIONS: HoLEP is an effective procedure for treating LUTS due to BPE, although it is not devoid of complications and sequelae, even in the hands of a highly experienced surgeon. PATIENT SUMMARY: Holmium laser treatment of the prostate to reduce its size has positive results for urinary function when performed by an experienced surgeon, even in complex cases, although there can be complications.

BACKGROUND: While the addition of androgen receptor signaling inhibitors (ARSIs) to androgen deprivation therapy (ADT) results in better of overall survival in patients with metastatic hormone-sensitive prostate cancer (mHSPC), information regarding health related quality of life (HR-QoL) is sparse. We aimed at summarizing current evidence on the impact of ARSIs on HR-QoL. METHODS: We performed a systematic review of the published literature on PubMed/EMBASE, Web of Science, SCOPUS, and the Cochrane libraries between January 2011 and April 2022. We included only phase III randomized controlled trials (RCT), which were selected according to the PRISMA guidelines. We aimed at evaluating differences in HR-QoL, assessed by validated patient reported outcomes instruments. We analyzed global scores and sub-domains such as sexual functioning, urinary symptoms, bowel symptoms, pain/fatigue, emotional and social/family wellbeing. We reported data descriptively. RESULTS: Six RCTs were included: two used enzalutamide with ADT as intervention arms (ARCHES, ENZAMET); one used apalutamide with ADT (TITAN); two abiraterone acetate and prednisone (AAP) with ADT (STAMPEDE, LATITUDE); and one darolutamide with ADT (ARASENS). Enzalutamide or AAP with ADT increase overall HR-QoL in comparison with ADT alone, ADT with first generation nonsteroideal anti-androgens or ADT with docetaxel, whereas apalutamide and darolutamide with ADT maintain HR-QoL similarly to ADT alone or ADT with docetaxel, respectively. Time to first deterioration of pain was longer with combination therapy with enzalutamide, AAP or darolutamide, but not with apalutamide. No worsening of emotional wellbeing was reported from the addition of ARSIs to ADT than ADT alone. CONCLUSIONS: The addition of ARSIs to ADT in mHSPC tends to increase overall HR-QoL and prolong time to first deterioration of pain/fatigue compared with ADT alone, ADT with first generation nonsteroideal anti-androgens, and ADT with docetaxel. ARSIs show a complex interaction with remaining HR-QoL domains. We advocate a standardization of HR-QoL measurement and reporting to allow further comparisons.
RESUMO
BACKGROUND: no data exist concerning functional and oncological outcomes of Retzius-sparing robot-assisted radical prostatectomy (RS-RARP), in patients previously treated with trans-urethral resection of the prostate (p-TURP), for benign prostate obstruction. Our study addressed the impact of p-TURP on immediate and 12-months urinary continence recovery (UCR), as well as peri-operative outcomes and surgical margins, after RS-RARP. METHODS: all patients treated with RS-RARP for prostate cancer at a single high-volume European institution, between 2010 and 2021, were identified and stratified according to p-TURP status. Logistic, Poisson and Cox regression models were performed. RESULTS: Of 1386 RS-RARP patients, 99 (7%) had history of p-TURP. Between p-TURP and no-TURP patients no differences were detected regarding both intra- and post-operative complications (p values = 0.9). The rates of immediate UCR were 40 vs 67% in p-TURP vs no-TURP patients (p < 0.001). At 12 months from RS-RARP, the rates of UCR were 68 vs 94% in p-TURP vs no-TURP patients (p < 0.001). At multivariable logistic and Cox regression models, p-TURP was independently associated, respectively, with lower immediate (odds ratio [OR]: 0.32, p < 0.001) and 12-months UCR (hazard ratio: 0.54, p < 0.001). At multivariable Poisson analyses, p-TURP predicted longer operative time (rate ratio: 1.08, p < 0.001) but not longer length of stay or time to catheter removal (p values > 0.05). Positive surgical margins rates were 23 vs 17% in p-TURP vs no-TURP patients (p = 0.1), which translated in a non-statistically significant multivariable OR of 1.14 (p = 0.6). CONCLUSIONS: p-TURP does not increase surgical morbidity but portends longer operative time and worse urinary continence after RS-RARP.

INTRODUCTION: The identification of variant histology (VH) has been recognized as a critical element in the diagnostic pathway of bladder cancer (BCa), both for prognostic and therapeutic implications. However, the current evidence on the oncological outcomes of patients harboring VH BCa mostly derives from studies including muscle-invasive disease. Consequently, the correct management of patients with non-muscle invasive bladder cancer (NMIBC) and VH is limited and conflicting, and the optimal therapeutic approach remains therefore controversial. EVIDENCE ACQUISITION: In this review, we aimed at reporting the current evidence on NMIBC with VH. EVIDENCE SYNTHESIS: Despite a constant increase in VH reporting at transurethral resection of bladder tumor (TURBT) specimens as compared to previous decades, we found that the incidence of VH is still sparse among studies. Furthermore, the agreement between TURBT and radical cystectomy (RC) specimens in VH identification is another matter of debate. Currently, most of the included studies report a poor overall concordance, especially for the micropapillary variant. Finally, while squamous and micropapillary variants are those associated with the worst survival outcomes, immediate RC is mostly considered for micropapillary tumors. Conversely, the survival benefit of immediate RC as compared to bladder-sparing approaches (i.e., BCG immunotherapy) for the other types of VH BCa is still an open question owing to the paucity of data available. CONCLUSIONS: Thus, in these patients, BCG treatment could be proposed considering the need for more intensive oncological surveillance.

BACKGROUND: The study aim was to report the results of Retzius-Sparing robot-assisted radical Prostatectomy (RSP) in high-risk prostate cancer (HR-PCa) patients in a multicentric setting of expert surgeons and to analyze predictors of positive surgical margins (PSMs) and urinary continence recovery. METHODS: We retrospectively evaluated all consecutive HR-PCa patients who underwent RSP by expert surgeons in 7 centers. Pre-, peri- and postoperative features were collected. Minimum surgical experience required was 100 RSP cases. The oncological outcomes evaluated were PSMs and biochemical relapse (BCR). Urinary continence was defined as no pad or safety pad. Erectile function was defined as erections sufficient for intercourse. RESULTS: We collected 579 patients operated by 9 surgeons. Median age was 66, median PSA was 9,6 ng/mL. ISUP biopsy was 1 in 3.8%, 2 in 23%, 3 in 32,6%, 4 in 19,9%, 5 in 20,7; median surgical time was 195 minutes. Pathological stage was pT2 in 40,1%, pT3a in 35,9%, pT3b in 23,1%, and pT4 in 0,9% of cases. PSMs were present in 31,3% of cases. Urinary continence was achieved in 66,8% of cases one week after catheter removal. At 22 months (median follow-up), 89,1% patients were continent, BCR occurred in 27,5% patients. In multivariate analysis, PSA, prostate volume, surgical time were independent predictors of PSMs; ASA score and PSMs predicted urinary continence. CONCLUSIONS: We report the first multicentric experience of RSP for HR-PCa. Considering HR cases as those with the worst functional results, 89% of continent patients confirms that RSP helps achieve good functional results.

OBJECTIVE: To evaluate the relationship between enlarged prostate, bulky median lobe (BML) or prior benign prostatic hyperplasia (BPH) surgery and perioperative functional, and oncological outcomes in high-risk (HR) prostate cancer (PCa) patients treated with Retzius-sparing robot-assisted radical prostatectomy (RS-RARP). METHODS: 320 HR-PCa patients treated with RS-RARP between 2011 and 2020 at a single high-volume center. The relationship between prostate volume, BML, prior BPH surgery and perioperative outcomes, Clavien-Dindo (CD) grade ≥ 2 90-day postoperative complications, positive surgical margins (PSMs), and urinary continence (UC) recovery was evaluated respectively in multivariable linear, logistic and Cox regression models. Complications were collected according to the standardized methodology proposed by EAU guidelines. UC recovery was defined as the use of zero or one safety pad. RESULTS: Overall, 5.9% and 5.6% had respectively a BML or prior BPH surgery. Median PV was 45 g (range: 14-300). The rate of focal and non-focal PSMs was 8.4% and 17.8%. 53% and 10.9% patients had immediate UC recovery and CD ≥ 2. The 1- and 2-yr UC recovery was 84 and 85%. PV (p = 0.03) and prior BPH surgery (p = 0.02) was associated with longer operative time. BML was independent predictor of time to bladder catheter removal (p = 0.001). PV was independent predictor of PSMs (OR: 1.02; p = 0.009). Prior BPH surgery was associated with lower UC recovery (HR: 0.5; p = 0.03). CONCLUSION: HR-PCa patients with enlarged prostate have higher risk of PSMs, while patients with prior BPH surgery have suboptimal UC recovery. These findings should help physicians for accurate preoperative counseling and to improve surgical planning in case of HR-PCa patients with challenging features.

Background: Retzius-sparing (RS) robot-assisted radical prostatectomy represents a valid surgical treatment option for prostate cancer (PCa) patients. However, the available evidence on the role of RS in high-risk (HR) PCa setting is sparse. Objective: To describe our RS technique for HR-PCa patients and to evaluate intra-, peri-, and postoperative oncological and functional outcomes. Design setting and participants: A total of 340 D'Amico HR-PCa patients underwent RS at a single high-volume centre between 2011 and 2020. Surgical procedure: Surgical procedures were performed by five experienced robotic surgeons. Measurements: Complications were collected according to the standardised methodology proposed by the European Association of Urology guidelines. Postoperative outcomes were evaluated in patients with complete follow-up data (n = 320). Biochemical recurrence (BCR) was defined as two consecutive prostate-specific antigen values of ≥0.2 ng/ml. Urinary continence (UC) recovery was defined as the use of zero or one safety pad. Kaplan-Meier and multivariable logistic and Cox regression models were performed. Results and limitations: Fourteen patients (4%) experienced intraoperative complications and 52 90-d complications occurred in 44 patients (14%), of whom 24 had Clavien-Dindo 3a/b. Final pathology reported 49% International Society of Urological Pathology (ISUP) grade 4-5, 55% ≥pT3a, and 28.8% positive surgical margins (PSMs; 9.4% focal and 19.4% extended PSMs). The median follow-up was 47 mo. Overall, 35.3% and 1.3% harboured BCR and died from PCa. At 4 yr of follow-up, BCR-free survival and additional treatment-free survival were 63.6% and 56.6%, respectively. ISUP 4-5 at biopsy (odds ratio [OR]: 2.6), prostate volume (OR: 1.03), partial or full nerve sparing (OR: 1.9), and full bladder neck preservation (OR: 2.2) were independent predictors of PSMs. Pathological ISUP 4-5 (hazard ratio [HR]: 1.5) and PSMs (HR: 2.3) were independent predictors of BCR. Pathological ISUP 4-5 (HR: 1.5), PSMs (HR: 2.4), pT ≥3b (HR: 1.8), and pN ≥1 (HR: 1.8) were independent predictors of additional treatment. Immediate UC recovery was recorded in 53% patients. The 1- and 2-yr UC recovery and erectile function recovery were, respectively, 84% and 85%, and 43% and 50%. Conclusions: RS in HR-PCa patients allows optimal intra-, peri-, and postoperative outcomes. The RS approach should be considered a valid surgical treatment option for HR-PCa patients in expert hands. Patient summary: Relying on the largest cohort of high-risk prostate cancer patients treated with Retzius sparing (RS), we observed that the RS approach is safe and allows optimal cancer control, without significantly compromising functional outcomes.
