High BMI, Aggressive Tumours and Long Console Time Are Independent Predictive Factors for Symptomatic Lymphocele Formation after Robot-Assisted Radical Prostatectomy and Pelvic Lymph Node Dissection.

INTRODUCTION: Lymphocele (LC) formation is a common complication which may cause severe symptoms after robot-assisted radical prostatovesiculectomy (RARP) with concomitant pelvic lymph node dissection (PLND). Compared to open radical prostatectomy, the amount of data on potential risk factors for LC formation is still limited. The aim of the present study was to identify risk factors for symptomatic LC formation (sLC) after RARP with PLND. METHODS: We used the data of a prospective multicentre series of 232 RARP patients which were treated between March 2017 and December 2017. The primary endpoint was the presence of sLC within 90 days. Asymptomatic LC (aLC) formation was also recorded. We evaluated clinical, perioperative, and histopathological criteria and compared their distribution in patients with and without post-operative sLC. Uni- and multivariable logistic regression analyses (MVAs) were performed to identify potential predictors for LC formation. Regarding the influence of patients' BMI, 2 models were calculated: BMI continuously (model 1) and BMI dichotomized with cut-off 30 kg/m2 (WHO definition, model 2). RESULTS: Post-operative sLC was present in 21 patients (9.1%), while aLC was detected in 49 patients (21.1%) 90 days after RARP with PLND. Patients with sLC showed higher median baseline PSA levels (9.8 vs. 8.1 ng/mL), higher prevalence of obesity (BMI >30; 42.9 vs. 19.9%), and longer median console time (180 vs. 165 min) compared to patients without sLC. On MVA higher BMI {model 1: OR 1.145 (confidence interval [CI] 1.025-1.278); model 2: OR 2.761 (1.045-7.296)}, longer console time (model 1: OR 1.013 [1.005-1.021]; model 2: OR 1.013 [1.005-1.020]) and an ISUP grade ≥3 (model 1: OR 3.247 [1.182-8.917]; model 2: OR 2.791 [1.050-7.423]) were identified as independent predictors for sLC development. CONCLUSION: Patients with aggressive tumours and higher BMI should be informed about a potentially increased risk for sLC formation. In case of a long console time, a close and regular follow-up should be considered to check for LC development.

Gender-Specific Variations in Professional and Personal Aspects among Senior Urology Physicians at German Centers: Results of a Web-Based Survey.

INTRODUCTION: Senior urology physicians represent a heterogeneous group covering various clinical priorities and career objectives. No reliable data on gender-specific variations among senior urology physicians are available concerning professional and personal aspects. METHODS: The objective of this study was to analyze professional perspectives, professional and personal settings, and individual career goals. A Web-based survey containing 55 items was designed which was available for senior physicians at German urologic centers between February and April 2019. Gender-specific differences were evaluated using bootstrap-adjusted multivariate logistic regression models. RESULTS: One hundred and ninety-two surveys were evaluable including 29 female senior physicians (15.1%). Ninety-five percent would choose urology again as their field of specialization - with no significant gender-specific difference. 81.2% of participants rate the position of senior physician as a desirable career goal (comparing sexes: p = 0.220). Based on multivariate models, male participants self-assessed themselves significantly more frequently autonomously safe performing laparoscopic, open, and endourologic surgery. Male senior physicians declared 7 times more often to run for the position of head of department/full professor. CONCLUSION: This first study on professional and personal aspects among senior urology physicians demonstrates gender-specific variations concerning self-assessment of surgical expertise and future career goals. The creation of well-orchestrated human resources development strategies especially adapted to the needs of female urologists seems advisable.

Oncological long-term outcome of whole gland HIFU and open radical prostatectomy: a comparative analysis.

PURPOSE: To compare the oncological long-term efficacy of whole gland high-intensity focused ultrasound (HIFU) therapy and radical prostatectomy (RP) in patients with clinically localized prostate cancer. METHODS: 418 patients after open RP (1997-2004) were compared with 469 patients after whole gland HIFU (1997-2009) without preselection. Oncological follow-up focused on biochemical relapse, salvage treatment, life status and cause-specific mortality. The univariate log rank test was used to compare both treatment options regarding overall survival (OS), cancer-specific survival (CSS), biochemical failure-free survival (BFS) and salvage treatment-free survival (STS). To adjust the treatment effect for further prognostic baseline variables, a multivariable Cox proportional hazards regression model was calculated for each end point. RESULTS: Median follow-up was 13.3 years in the RP group and 6.5 years in the HIFU group. OS/CSS/BFS/STS rates at 10 years were 91/98/80/80% after RP and 76/94/70/71% after HIFU. HIFU therapy (reference RP) was a significant and independent predictor for an inferior OS, CSS and STS. In subgroup analysis, HIFU provided significantly reduced CSS for intermediate- (p = 0.010) and high-risk patients (p = 0.048); whereas no difference was observed in the low-risk group, intermediate-risk HIFU patients showed a significantly inferior STS (p = 0.040). CONCLUSIONS: While whole gland HIFU offers a comparable long-term efficacy for low-risk patients, sufficient cancer control for high-risk patients is more than doubtful. For the subgroup of intermediate-risk patients, CSS rates seem to be comparable up to 10 years suggesting that HIFU may be an alternative for older patients, although a higher risk of salvage treatment should be expected.

Oncological Outcome and Value of Postoperative Magnetic Resonance Imaging after Focal High-Intensity Focused Ultrasound Therapy for Prostate Cancer.

INTRODUCTION: Focal therapy (FT) by high-intensity focused ultrasound (HIFU) is an emerging option for localized prostate cancer (PC). Due to the lack of long-term data, a close monitoring after FT is essential, but there are still uncertainties about the optimal follow-up regimen. Here we report on a series of FT-HIFU patients with the focus on oncological short-term outcome and the value of postoperative magnetic resonance imaging (MRI). METHODS: We included 21 patients treated by FT-HIFU using the Focal One® device (EDAP TMS, France) between November 2015 and May 2018. PC localization was assessed by preoperative multiparametric MRI (mpMRI) and transrectal ultrasound-guided targeted and systematic biopsy. Oncological follow-up included prostate-specific antigen (PSA) development, mpMRI, control biopsies (targeted and systematic) of the treated and untreated areas and salvage treatment rate. Control mpMRI and control biopsy were performed after 6-12 months. RESULTS: 15 patients (71.4%) were managed by focal ablation of a solitary lesion, while 6 patients (28.6%) underwent zonal tumor ablation. All patients underwent control mpMRI and biopsy. After a mean follow-up period of 11.7 months, cancer relapse was detected in 8 patients (38.1%), with 4 patients (19%) having infield recurrence. Postoperative mpMRI revealed 3 out of 4 infield PC relapses but missed 5 out of 7 outfield relapses. Clinically significant cancer recurrence was present in 1 patient (4.8%), which was missed by mpMRI. Posttreatment mpMRI had a sensitivity, specificity, positive and negative predictive value of 62.5, 92.3, 83.3 and 80.0%, respectively, for overall relapse detection based on patient level. Only 1 of the 8 recurrences was suspected based on PSA progression. 4 of the 8 patients with PC relapse (19%) underwent salvage therapy (2 patients by radical prostatectomy, 2 patients by salvage FT-HIFU). CONCLUSION: Postoperative mpMRI might play a valuable role during follow-up after focal HIFU therapy, particularly in terms of infield relapse detection. Irrespective of mpMRI results, the repeat biopsy regimen should incorporate systematic biopsy including cores of the treated and untreated prostate areas.

Expression, localisation and potential significance of aquaporins in benign and malignant human prostate tissue.

BACKGROUND: To study the expression pattern, localisation and potential clinical significance of aquaporin water channels (AQP) both in prostate cancer (PC) cell lines and in benign and malignant human prostate tissue. METHODS: The AQP transcript and protein expression of HPrEC, LNCaP, DU-145 and PC3 cell lines was investigated using reverse transcriptase polymerase chain reaction (RT-PCR) and immunofluorescence (IF) microscopy labelling. Immunohistochemistry (IHC) was performed to assess AQP protein expression in surgical specimens of benign prostatic hyperplasia as well as in PC. Tissue mRNA expression of AQPs was quantified by single-step reverse transcriptase quantitative polymerase chain reaction (qPCR). Relative gene expression was determined using the 40-ΔCT method and correlated to clinicopathological parameters. RESULTS: Transcripts of AQP 1, 3, 4, 7, 8, 10 and 11 were expressed in all four cell lines, while AQP 9 transcripts were not detected in malignant cell lines. IF microscopy confirmed AQP 3, 4, 5, 7 and 9 protein expression. IHC revealed highly heterogeneous AQP 3 protein expression in PC specimens, with a marked decrease in expression in tumours of increasing malignancy. Loss of AQP 9 was shown in PC specimens. mRNA expression of AQP3 was found to be negatively correlated to PSA levels (ρ = - 0.354; p = 0.013), D'Amico risk stratification (ρ = - 0.336; p = 0.012), ISUP grade (ρ = - 0.321; p = 0.017) and Gleason score (ρ = - 0.342; p = 0.011). CONCLUSIONS: This is the first study to systematically characterize human prostate cell lines, benign prostatic hyperplasia and PC in relation to all 13 members of the AQP family. Our results indicate the differential expression of several AQPs in benign and malignant prostate tissue. A significant correlation was observed between AQP 3 expression and tumour grade, with progressive loss in more malignant tumours. Taken together, AQPs may play a role in the progression of PC and AQP expression patterns may serve as a prognostic marker.

Anatomical study of pelvic nerves in relation to seminal vesicles, prostate and urethral sphincter: immunohistochemical staining, computerized planimetry and 3-dimensional reconstruction.

PURPOSE: Studies of male pelvic neuroanatomy are mandatory to improve functional outcome after radical prostatectomy. We performed a topographical investigation of nerves on the course from the seminal vesicles along the prostate toward the striated urethral sphincter. MATERIALS AND METHODS: Serial whole mount sections (1 mm intervals) of pelvic blocks of human adult male autopsy cadavers were investigated after immunohistochemical nerve staining. Computerized nerve quantification and planimetry of the total nerve surface area were performed within defined regions (ventral, ventrolateral, dorsolateral and dorsal) at the levels of the seminal vesicles and prostate, and at the striated urethral sphincter. The distance between the seminal vesicles and the nerves was measured. For improved topographical understanding 3-dimensional reconstructions were created. Differences between 3 independent variables were tested with the nonparametric Kruskal-Wallis test. RESULTS: We studied a total of 969 whole mount sections of 5 cadavers. Nerves were arranged in a vertical plate lateral to the seminal vesicles. Mean ± SD distance to the seminal vesicles was 1.68 ± 0.84, 1.50 ± 0.12 and 1.76 ± 0.37 mm at the tip, middle and base, respectively. Periprostatic nerves were mainly found dorsolaterally. At the striated urethral sphincter 38.9% of nerves had shifted to the dorsal region. The total nerve surface area decreased significantly from the seminal vesicle tip (50.2 mm(2)) to the striated urethral sphincter level (13.3 mm(2)) (p = 0.0004). CONCLUSIONS: Our findings underline that during nerve sparing prostatectomy nerve damage might occur during mobilization of the entire seminal vesicles, apical dissection and posterior reconstruction of the rhabdosphincter. Nerve planimetry revealed that 75% of the nerves from the seminal vesicles do not reach the striated urethral sphincter level and seem to innervate structures other than the corpora cavernosa.

Correlation of pretreatment clinical parameters and PSA nadir after high-intensity focused ultrasound (HIFU) for localised prostate cancer.

OBJECTIVE: To determine which pretreatment clinical parameters were predictive of a low prostate-specific antigen (PSA) nadir following high-intensity focused ultrasound (HIFU) treatment. PATIENTS AND METHODS: Retrospective study of patients with clinically localised prostate cancer undergoing HIFU at a single centre between December 1997 and September 2009. Whole-gland treatment was applied. Patients also included if they had previously undergone transurethral resection of the prostate (TURP). TURP was also conducted simultaneously to HIFU. Biochemical failure based on Phoenix definition (PSA nadir + 2). Univariate and multivariate analysis of pretreatment clinical parameters conducted to assess those factors predictive of a PSA nadir ≤0.2 and >0.2 ng/ml. RESULTS: Mean (SD) follow-up was 6.2 (2.8) years; median (range) was 6.3 (1.1-12.2) years. Kaplan-Meier estimate of biochemical disease-free survival rate at 8 years was 83 and 48 % for patients achieving a PSA nadir of ≤0.2 and >0.2 ng/ml, respectively. Prostate volume and incidental finding of cancer were significant predictors of low PSA nadir (≤0.2 ng/ml). CONCLUSIONS: Prostate volume and incidental finding of cancer could be predictors for oncologic success of HIFU based on post-treatment PSA nadir.

Outcome of patients with pathological tumor stage T3 urothelial carcinoma of the bladder following radical cystectomy in a single-center series with 116 patients.

OBJECTIVE: Outcome prediction of pT3 urothelial carcinoma of the bladder (UCB) after radical cystectomy (RC) remains challenging. The objective of our study was to determine high-risk patients with poor survival outcome in a heterogeneous group substaged pT3 who might profit from early adjuvant chemotherapy. MATERIALS AND METHODS: We compiled clinicopathological and immunohistochemical data of E-cadherin (E-cad) expression in 116 patients with pT3 UCB after RC in our single-center series. Multivariable Cox regression models including substaged pT3 established clinicopathological features, and the expression of the predictive immunohistochemical feature E-cad was used to identify independent predictors on progression-free (PFS), cancer-specific (CSS) and overall survival (OS), respectively. RESULTS: No significant differences were found addressing clinicopathological data and substaged pT3. In multivariable Cox regression models, lymph node involvement was an independent predictor for PFS (p < 0.001), CSS (p < 0.001) and OS (p = 0.002), respectively. Lymphovascular invasion (LVI) significantly influenced PFS (p = 0.016). ASA score 3/4 independently predicted CSS (p = 0.049) and OS (p = 0.032). Neither pT3 substages nor E-cad expression were significant prognosticators for survival. CONCLUSIONS: In pT3 UCB patients with ASA 3/4, positive lymph node status and/or presence of LVI, administration of chemotherapy should be considered due to the high risk of poor oncological outcome. The immunohistochemical marker E-cad was not an independent predictor.

Impact of Peritoneal Interposition Flap on Patients Undergoing Robot-assisted Radical Prostatectomy and Pelvic Lymph Node Dissection: A Systematic Review and Meta-analysis of Randomized Controlled Trials.

CONTEXT: Symptomatic lymphocele (sLC) occurs at a frequency of 2-10% after robot-assisted radical prostatectomy (RARP) with pelvic lymph node dissection (PLND). Construction of bilateral peritoneal interposition flaps (PIFs) subsequent to completion of RARP + PLND has been introduced to reduce the risk of lymphocele, and was initially evaluated on the basis of retrospective studies. OBJECTIVE: To conduct a systematic review and meta-analysis of only randomized controlled trials (RCTs) evaluating the impact of PIF on the rate of sLC (primary endpoint) and of overall lymphocele (oLC) and Clavien-Dindo grade ≥3 complications (secondary endpoints) to provide the best available evidence. EVIDENCE ACQUISITION: In accordance with the Preferred Reporting Items for Meta-Analyses statement for observational studies in epidemiology, a systematic literature search using the MEDLINE (PubMed), Cochrane Central Register of Controlled Trials (CENTRAL), and EMBASE databases up to February 3, 2023 was performed to identify RCTs. The risk of bias (RoB) was assessed using the revised Cochrane RoB tool for randomized trials. Meta-analysis used random-effect models to examine the impact of PIF on the primary and secondary endpoints. EVIDENCE SYNTHESIS: Four RCTs comparing outcomes for patients undergoing RARP + PLND with or without PIF were identified: PIANOFORTE, PerFix, ProLy, and PLUS. PIF was associated with odds ratios of 0.46 (95% confidence interval [CI] 0.23-0.93) for sLC, 0.51 (95% CI 0.38-0.68) for oLC, and 0.41 (95% CI 0.21-0.83) for Clavien-Dindo grade ≥3 complications. Functional impairment resulting from PIF construction was not observed. Heterogeneity was low to moderate, and RoB was low. CONCLUSIONS: PIF should be performed in patients undergoing RARP and simultaneous PLND to prevent or reduce postoperative sLC. PATIENT SUMMARY: A significant proportion of patients undergoing prostate cancer surgery have regional lymph nodes removed. This part of the surgery is associated with a risk of postoperative lymph collections (lymphocele). The risk of lymphocele can be halved via a complication-free surgical modification called a peritoneal interposition flap.

Long-Term Follow-Up of Peritoneal Interposition Flap in Symptomatic Lymphocele Reduction following Robot-Assisted Radical Prostatectomy: Insights from the PIANOFORTE Trial.

The available randomised controlled trials (RCTs) assessing the influence of peritoneal interposition flaps (PIF) on the reduction of symptomatic lymphoceles (sLCs) post robot-assisted radical prostatectomy (RARP) do not constitute a sufficient follow-up (FU) to assess the long-term effects. The PIANOFORTE trial was the first of these RCTs, showing no sLC reduction at the 3-month FU. Therefore, all 232 patients from the PIANOFORTE trial were invited for long-term FU. One hundred seventy-six patients (76%) presented themselves for FU and constituted the study group (SG). The median FU duration was 43 months. No significant differences in group allocation or LC endpoints at 90 days were observed between SG patients and patients not presenting themselves for the FU. During the FU period, four patients (2.3%) in the SG developed sLCs, and six patients (3.4%) developed asymptomatic lymphoceles (aLCs), which persisted in five patients (2.9%). There were no significant differences between PIF and non-PIF regarding sLC/aLC formation or persistence, newly developed complications, stress urinary incontinence or biochemical/clinical tumour recurrence. Therefore, this long-term FU confirms the primary outcomes of the PIANOFORTE trial that, while PIF does not impact complications or functionality, it does not reduce sLC/aLC rates. Furthermore, it shows the potential occurrence of LC after the third postoperative month.

Urine-Based Biomarker Test Uromonitor® in the Detection and Disease Monitoring of Non-Muscle-Invasive Bladder Cancer-A Systematic Review and Meta-Analysis of Diagnostic Test Performance.

Optimal urine-based diagnostic tests (UBDT) minimize unnecessary follow-up cystoscopies in patients with non-muscle-invasive bladder-cancer (NMIBC), while accurately detecting high-grade bladder-cancer without false-negative results. Such UBDTs have not been comprehensively described upon a broad, validated dataset, resulting in cautious guideline recommendations. Uromonitor®, a urine-based DNA-assay detecting hotspot alterations in TERT, FGFR3, and KRAS, shows promising initial results. However, a systematic review merging all available data is lacking. Studies investigating the diagnostic performance of Uromonitor® in NMIBC until November 2023 were identified in PubMed, Embase, Web-of-Science, Cochrane, Scopus, and medRxiv databases. Within aggregated analyses, test performance and area under the curve/AUC were calculated. This project fully implemented the PRISMA statement. Four qualifying studies comprised a total of 1190 urinary tests (bladder-cancer prevalence: 14.9%). Based on comprehensive analyses, sensitivity, specificity, positive-predictive value/PPV, negative-predictive value/NPV, and test accuracy of Uromonitor® were 80.2%, 96.9%, 82.1%, 96.6%, and 94.5%, respectively, with an AUC of 0.886 (95%-CI: 0.851-0.921). In a meta-analysis of two studies comparing test performance with urinary cytology, Uromonitor® significantly outperformed urinary cytology in sensitivity, PPV, and test accuracy, while no significant differences were observed for specificity and NPV. This systematic review supports the use of Uromonitor® considering its favorable diagnostic performance. In a cohort of 1000 patients with a bladder-cancer prevalence of ~15%, this UBDT would avert 825 unnecessary cystoscopies (true-negatives) while missing 30 bladder-cancer cases (false-negatives). Due to currently limited aggregated data from only four studies with heterogeneous quality, confirmatory studies are needed.

Second TURB, restaging TURB or repeat TURB in primary T1 non-muscle invasive bladder cancer: impact on prognosis?

PURPOSE: A re-transurethral resection of the bladder (re-TURB) is a well-established approach in managing non-muscle invasive bladder cancer (NMIBC) for various reasons: repeat-TURB is recommended for a macroscopically incomplete initial resection, restaging-TURB is required if the first resection was macroscopically complete but contained no detrusor muscle (DM) and second-TURB is advised for all completely resected T1-tumors with DM in the resection specimen. This study assessed the long-term outcomes after repeat-, second-, and restaging-TURB in T1-NMIBC patients. METHODS: Individual patient data with tumor characteristics of 1660 primary T1-patients (muscle-invasion at re-TURB omitted) diagnosed from 1990 to 2018 in 17 hospitals were analyzed. Time to recurrence, progression, death due to bladder cancer (BC), and all causes (OS) were visualized with cumulative incidence functions and analyzed by log-rank tests and multivariable Cox-regression models stratified by institution. RESULTS: Median follow-up was 45.3 (IQR 22.7-81.1) months. There were no differences in time to recurrence, progression, or OS between patients undergoing restaging (135 patients), second (644 patients), or repeat-TURB (84 patients), nor between patients who did or who did not undergo second or restaging-TURB. However, patients who underwent repeat-TURB had a shorter time to BC death compared to those who had second- or restaging-TURB (multivariable HR 3.58, P = 0.004). CONCLUSION: Prognosis did not significantly differ between patients who underwent restaging- or second-TURB. However, a worse prognosis in terms of death due to bladder cancer was found in patients who underwent repeat-TURB compared to second-TURB and restaging-TURB, highlighting the importance of separately evaluating different indications for re-TURB.

Fourteen-year oncological and functional outcomes of high-intensity focused ultrasound in localized prostate cancer.

UNLABELLED: WHAT'S KNOWN ON THE SUBJECT? AND WHAT DOES THE STUDY ADD?: High-intensity focused ultrasound (HIFU) is an alternative treatment option for localized prostate cancer (PCa), which is applied for over 15 years. There are conflicting recommendations for HIFU among urological societies, which can be explained by the lack of prospective controlled studies, reports on preselected patient populations and limited follow-up providing little information on overall and cancer-specific survival. We report on a large, unselected consecutive patient series of patients who have undergone primary HIFU for clinically localized PCa with the longest follow-up in current literature. Our results improve the understanding of the oncological efficacy, morbidity and side effects of primary HIFU. OBJECTIVE: To assess the safety, functional and oncological long-term outcomes of high-intensity focused ultrasound (HIFU) as a primary treatment option for localized prostate cancer (PCa). PATIENTS AND METHODS: We conducted a retrospective single-centre study on 538 consecutive patients who underwent primary HIFU for clinically localized PCa between November 1997 and September 2009. Factors assessed were: biochemical disease-free survival (BDFS) according to Phoenix criteria (prostate-specific antigen nadir + 2 ng/mL); metastatic-free, overall and PCa-specific survival; salvage treatment; side effects; potency; and continence status. RESULTS: The mean (sd; range) follow-up was 8.1 (2.9; 2.1-14.0) years. The actuarial BDFS rates at 5 and 10 years were 81 and 61%, respectively. The 5-year BDFS rates for low-, intermediate- and high-risk patients were 88, 83 and 48%, while the 10-year BDFS rates were 71, 63 and 32%, respectively. Metastatic disease was reported in 0.4, 5.7 and 15.4% of low-, intermediate- and high-risk patients, respectively. The salvage treatment rate was 18%. Seventy-five (13.9%) patients died. PCa-specific death was registered in 18 (3.3%) patients (0, 3.8 and 11% in the low-, intermediate- and high-risk groups, respectively). Side effects included bladder outlet obstruction (28.3%), Grade I, II and III stress urinary incontinence (13.8, 2.4 and 0.7%, respectively) and recto-urethral fistula (0.7%). Preserved potency was 25.4% (in previously potent patients). CONCLUSIONS: The study demonstrates the efficacy and safety of HIFU for localized PCa. HIFU is a therapeutic option for patients of advanced age, in the low- or intermediate-risk groups, and with a life expectancy of ∼10 years.

Prognosis of Primary Papillary Ta Grade 3 Bladder Cancer in the Non-muscle-invasive Spectrum.

BACKGROUND: Ta grade 3 (G3) non-muscle-invasive bladder cancer (NMIBC) is a relatively rare diagnosis with an ambiguous character owing to the presence of an aggressive G3 component together with the lower malignant potential of the Ta component. The European Association of Urology (EAU) NMIBC guidelines recently changed the risk stratification for Ta G3 from high risk to intermediate, high, or very high risk. However, prognostic studies on Ta G3 carcinomas are limited and inconclusive. OBJECTIVE: To evaluate the prognostic value of categorizing Ta G3 compared to Ta G2 and T1 G3 carcinomas. DESIGN, SETTING, AND PARTICIPANTS: Individual patient data for 5170 primary Ta-T1 bladder tumors from 17 hospitals were analyzed. Transurethral resection of the tumor was performed between 1990 and 2018. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Time to recurrence and time to progression were analyzed using cumulative incidence functions, log-rank tests, and multivariable Cox-regression models with interaction terms stratified by institution. RESULTS AND LIMITATIONS: Ta G3 represented 7.5% (387/5170) of Ta-T1 carcinomas of which 42% were classified as intermediate risk. Time to recurrence did not differ between Ta G3 and Ta G2 (p = 0.9) or T1 G3 (p = 0.4). Progression at 5 yr occurred for 3.6% (95% confidence interval [CI] 2.7-4.8%) of Ta G2, 13% (95% CI 9.3-17%) of Ta G3, and 20% (95% CI 17-23%) of T1 G3 carcinomas. Time to progression for Ta G3 was shorter than for Ta G2 (p < 0.001) and longer than for T1 G3 (p = 0.002). Patients with Ta G3 NMIBC with concomitant carcinoma in situ (CIS) had worse prognosis and a similar time to progression as for patients with T1 G3 NMIBC with CIS (p = 0.5). Multivariable analyses for recurrence and progression showed similar results. CONCLUSIONS: The prognosis of Ta G3 tumors in terms of progression appears to be in between that of Ta G2 and T1 G3. However, patients with Ta G3 NMIBC with concomitant CIS have worse prognosis that is comparable to that of T1 G3 with CIS. Our results support the recent EAU NMIBC guideline changes for more refined risk stratification of Ta G3 tumors because many of these patients have better prognosis than previously thought. PATIENT SUMMARY: We used data from 17 centers in Europe and Canada to assess the prognosis for patients with stage Ta grade 3 (G3) non-muscle-invasive bladder cancer (NMIBC). Time to cancer progression for Ta G3 cancer differed from both Ta G2 and T1 G3 tumors. Our results support the recent change in the European Association of Urology guidelines for more refined risk stratification of Ta G3 NMIBC because many patients with this tumor have better prognosis than previously thought.

Oncological Long-term Outcome After Whole-gland High-intensity Focused Ultrasound for Prostate Cancer-21-yr Follow-up.

BACKGROUND: Owing to the morbidity of established radical treatment options for prostate cancer, alternative whole-gland and focal treatment strategies have emerged. High-intensity focused ultrasound (HIFU) is one of the most studied sources for tissue ablation and has been used since the 1990s. OBJECTIVE: To provide 21-yr oncological long-term follow-up data of an unselected series of patients who underwent whole-gland HIFU for nonmetastatic prostate cancer. DESIGN, SETTING, AND PARTICIPANTS: A total of 674 patients were treated between November 1997 and November 2012 in one university center. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The oncological outcome was assessed by biopsy failure-free survival (BFFS), salvage treatment-free survival (STFS), metastasis-free survival (MFS), cancer-specific survival (CSS), and overall survival (OS). Multivariable Cox proportional hazard regression analyses were performed to estimate the prognostic relevance of clinical variables. RESULTS AND LIMITATIONS: In total, 560 patients were included into the evaluation and the median follow-up was 15.1 yr, with a range up to 21.4 yr. At 15 yr, CSS rates for low-, intermediate-, and high-risk patients were 95%, 89%, and 65%, respectively; MFS, STFS-1 (salvage treatment other than HIFU), STFS-2 (salvage treatment including repeat HIFU), and BFFS rates were 91%, 85%, and 58%; 77%, 63%, and 29%; 67%, 52%, and 28%; and 82%, 73%, and 47%, respectively. Preoperative high-risk category was an independent predictor of inferior OS, CSS, MFS, STFS, and BFFS. CONCLUSIONS: Although whole-gland HIFU achieved good long-term cancer control in low- and intermediate-risk patients, high-risk patients should not be treated routinely by HIFU. Intermediate-risk patients achieve high CSS and MFS rates, but a relevant salvage treatment rate has to be reckoned with. Long-term data after whole-gland therapy might help derive implications for focal treatment sources and patient selection. PATIENT SUMMARY: Long-term data after whole-gland high-intensity focused ultrasound (HIFU) therapy are crucial to prove its oncological efficacy, and may help derive implications for focal treatment strategies and patient selection. In this context, whole-gland HIFU achieved good long-term cancer control up to 21 yr in low- and intermediate-risk prostate cancer (PCa) patients. Owing to considerably inferior long-term cancer control, it should not routinely be used in high-risk PCa patients.

[Impact of the experience of urological senior physicians in Germany on professional and personal aspects]. / Welchen Einfluss hat die Dauer der Oberarzttätigkeit auf die Berufsausübung und Zufriedenheit urologischer OberärztInnen in Deutschland?

BACKGROUND: Urological senior physicians in Germany are a heterogeneous group with various clinical priorities and career objectives. To date, there are no reliable data concerning the impact of the time span for which senior physicians have been holding their position on professional, personal and position-linked aspects. MATERIAL AND METHODS: The objective of this study was a comparative analysis of perspectives, private and professional settings, specific job-related activities and individual professional goals of urological senior physicians in Germany based on their experience in this position assessed as number of years (dichotomised at 8 years as senior physician). As part of a cross-sectional study, a 55-item web-based questionnaire was designed, which was sent via a link to members of a mailing list of the German Society of Urology. The survey was available for urological senior physicians between February and April 2019. Group differences were evaluated using multivariate regression models. RESULTS: 107 of 192 evaluable questionnaires were completed by senior physicians holding this position for less than 8 years (< 8y senior physicians), 85 were completed by senior physicians holding this position for at least 8 years (≥ 8y senior physicians). < 8y senior physicians worked significantly more often at university hospitals (42.1 % vs. 18.8 %, p = 0.002). Overall, 82.4 % of ≥ 8y senior physicians assessed themselves autonomously safe in performing open surgery, compared to 39.3 % among < 8y senior physicians (p < 0.001). No significant differences concerning the self-assessment were found for endourological procedures (94.1 % vs. 87.9 %) and for the overall lower-rated self-assessment concerning laparoscopy (29.4 % vs. 20.6 %) and robotic surgery (14.1 % vs. 10.3 %). Despite the high management responsibility associated with their position, only about one third of participants (34.8 %) had received specific postgraduate education preparing them for managing and executive tasks. CONCLUSION: This study shows significant differences among senior physicians regarding surgical skills depending on the time span they hold their position. Moreover, there is considerable dissatisfaction regarding the development of leadership skills and the preparation for managing tasks. In order to ensure availability of senior staff members for the field of urology in the future, it is important to consider their professional needs and to overcome existing shortcomings by education programs within well-orchestrated human resources development strategies.

Patients Regret Their Choice of Therapy Significantly Less Frequently after Robot-Assisted Radical Prostatectomy as Opposed to Open Radical Prostatectomy: Patient-Reported Results of the Multicenter Cross-Sectional IMPROVE Study.

Patient's regret (PatR) concerning the choice of therapy represents a crucial endpoint for treatment evaluation after radical prostatectomy (RP) for prostate cancer (PCA). This study aims to compare PatR following robot-assisted (RARP) and open surgical approach (ORP). A survey comprising perioperative-functional criteria was sent to 1000 patients in 20 German centers at a median of 15 months after RP. Surgery-related items were collected from participating centers. To calculate PatR differences between approaches, a multivariate regressive base model (MVBM) was established incorporating surgical approach and demographic, center-specific, and tumor-specific criteria not primarily affected by surgical approach. An extended model (MVEM) was further adjusted by variables potentially affected by surgical approach. PatR was based on five validated questions ranging 0−100 (cutoff >15 defined as critical PatR). The response rate was 75.0%. After exclusion of patients with laparoscopic RP or stage M1b/c, the study cohort comprised 277/365 ORP/RARP patients. ORP/RARP patients had a median PatR of 15/10 (p < 0.001) and 46.2%/28.1% had a PatR >15, respectively (p < 0.001). Based on the MVBM, RARP patients showed PatR >15 relative 46.8% less frequently (p < 0.001). Consensual decision making regarding surgical approach independently reduced PatR. With the MVEM, the independent impact of both surgical approach and of consensual decision making was confirmed. This study involving centers of different care levels showed significantly lower PatR following RARP.

T1G1 Bladder Cancer: Prognosis for this Rare Pathological Diagnosis Within the Non-muscle-invasive Bladder Cancer Spectrum.

BACKGROUND: The pathological existence and clinical consequence of stage T1 grade 1 (T1G1) bladder cancer are the subject of debate. Even though the diagnosis of T1G1 is controversial, several reports have consistently found a prevalence of 2-6% G1 in their T1 series. However, it remains unclear if T1G1 carcinomas have added value as a separate category to predict prognosis within the non-muscle-invasive bladder cancer (NMIBC) spectrum. OBJECTIVE: To evaluate the prognostic value of T1G1 carcinomas compared to TaG1 and T1G2 carcinomas within the NMIBC spectrum. DESIGN, SETTING, AND PARTICIPANTS: Individual patient data for 5170 primary Ta and T1 bladder tumors from 17 hospitals in Europe and Canada were analyzed. Transurethral resection (TUR) was performed between 1990 and 2018. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Time to recurrence and progression were analyzed using cumulative incidence functions, log-rank tests, and multivariable Cox regression models stratified by institution. RESULTS AND LIMITATIONS: T1G1 represented 1.9% (99/5170) of all carcinomas and 5.3% (99/1859) of T1 carcinomas. According to primary TUR dates, the proportion of T1G1 varied between 0.9% and 3.5% per year, with similar percentages in the early and later calendar years. We found no difference in time to recurrence between T1G1 and TaG1 (p = 0.91) or between T1G1 and T1G2 (p = 0.30). Time to progression significantly differed between TaG1 and T1G1 (p < 0.001) but not between T1G1 and T1G2 (p = 0.30). Multivariable analyses for recurrence and progression showed similar results. CONCLUSIONS: The relative prevalence of T1G1 diagnosis was low and remained constant over the past three decades. Time to recurrence of T1G1 NMIBC was comparable to that for other stage/grade NMIBC combinations. Time to progression of T1G1 NMIBC was comparable to that for T1G2 but not for TaG1, suggesting that treatment and surveillance of T1G1 carcinomas should be more like the approaches for T1G2 NMIBC in accordance with the intermediate and/or high risk categories of the European Association of Urology NMIBC guidelines. PATIENT SUMMARY: Although rare, stage T1 grade 1 (T1G1) bladder cancer is still diagnosed in daily clinical practice. Using individual patient data from 17 centers in Europe and Canada, we found that time to progression of T1G1 cancer was comparable to that for T1G2 but not TaG1 cancer. Therefore, our results suggest that primary T1G1 bladder cancers should be managed with more aggressive treatment and more frequent follow-up than for low-risk bladder cancer.

Epidemiology and therapy of symptomatic lymphoceles after robot-assisted radical prostatectomy (RARP).

BACKGROUND: Lymphoceles are a common postoperative complication after radical prostatectomy with pelvic lymphadenectomy. Therapeutic options include cannulation and drainage (CD), drainage and instillation (DI), or laparoscopic fenestration (LF). The aim of this study was to investigate the epidemiology of symptomatic lymphoceles (SLC) and evaluate the treatment options. METHODS: We retrospectively analysed all patients who underwent robot-assisted radical prostatectomy (RARP) at our clinic from January 1, 2014 to December 31, 2018. All documented lymphoceles of these patients were recorded and analysed with regard to symptoms, possible infection and the treatment option (or options) chosen. RESULTS: We were able to include all 1,029 patients who underwent RARP in the aforementioned period of time. Of these, 18.1% were diagnosed with a lymphocele either when discharged or when readmitted and 6.9% experienced an SLC requiring treatment. Thirteen-point-seven percent of patients readmitted with SLC showed an accompanying thrombosis. Due to recurring or bilateral SLCs receiving different treatment options for each side, there was a total of 115 SLCs treated. CD was carried out in 102 cases. Twenty-point-six percent of patients were sufficiently treated this way, the rest required further treatment or experienced recurrences not requiring further treatment. DI was carried out in 56 cases. Of those patients, 46.4% were sufficiently treated. LF was carried out in 54 cases (either after CD, or after DI, or primarily). Of those patients, 98.1% were treated sufficiently. LF had a statistically significant higher success rate compared to CD and DI (P<0.001 respectively). CONCLUSIONS: The study confirmed the significance of SLC as a common complication after RARP. LF turned out to be the most effective treatment option for SLC, while CD as well as DI have not been proven effective.

Acceptance, Indications and Chances of Focal Therapy in Localized Prostate Cancer: A Real-World Perspective of Urologists in Germany.

Purpose: Focal therapy (FT) became a frequently discussed treatment strategy of localized prostate cancer (PCa), but the acceptance and evaluation of FT by practicing urologists are still unclear. Methods: A 25-item anonymized online questionnaire (SurveyMonkey®) was compiled by the German Society of Residents in Urology Academics Prostate Cancer Working Group and sent to the members of the German association of Urology. Logistic regression analysis was performed to determine parameters for suggestion FT. Results: Two hundred ten urologists (median age 49 years) participated, from which 72% stated PCa as their main treatment focus. Ninety-nine percent of urologists were aware of and 54% wanted to improve their knowledge about FT. Sixty-five percent do not treat PCa with FT. FT is seen as an alternative to active surveillance and radiotherapy/radical prostatectomy by 66% and 37%, respectively. Regarding FT treatment strategies, 35% and 45% would treat all or all significant PCa foci, respectively, whereas 19% would treat mainly the index foci. Currently, 27% believe that FT will be an option as standard treatment in future, but 48% would not suggest FT to their patients, owing to an absence of evidence and insufficient diagnostic tools for proper patient selection today. Suggesting FT to patients is associated with self-performing FT (odds ratio [OR] 2.88, 95% confidence interval [CI] 1.31-6.31) and believing in FT as a standard treatment in future (OR 9.05, 95% CI 6.68-22.30) (both p < 0.01). Conclusion: FT has currently no wide acceptance in German practicing urologists, mainly attributable to an absence of evidence for FT superiority compared to standard treatments.
