Objective To examine whether percentage of tumour volume (%TV) and percentage of high-grade tumour volume (%HGTV) help to better identify men at higher risk of early biochemical recurrence (BCR) after radical prostatectomy (RP) for non-metastatic high-risk prostate cancer, as early BCR after RP might be associated with higher risk of metastases and cancer-specific mortality. Patients and Methods We examined the data of 595 men treated with RP for non-metastatic high-risk prostate cancer between 1992 and 2011 at two European tertiary care centres. Kaplan-Meier analyses were used to graphically depict 2-year BCR-free survival. Multivariable Cox regression models addressed early BCR. We tested whether addition of %TV and %HGTV to a multivariable Cox regression model helps to increase a model's predictive accuracy (PA) for prediction of early BCR. Results In all, 32 men (10%) with specimen-confined prostate cancer (pT2-pT3a, negative surgical margin, pN0) and 67 men (24%) with non-specimen-confined prostate cancer had early BCR. After stratification according to %HGTV (%HGTV threshold: ≤33.33 vs >33.33%), the 2-year BCR-free survival rates were respectively 93 vs 60% (log-rank P < 0.001). In multivariable Cox regression models %HGTV emerged as an independent predictor of early BCR (P < 0.001), whereas %TV did not (P > 0.05). However, adding %HGTV (regardless of its coding) to other covariates in multivariable Cox regression analysis did not increase the model's PA in a meaningful fashion compared with the use of the detailed Gleason grading system (6 vs 7a vs 7b vs 8 vs 9-10). Conclusions In a large cohort of patients with high-risk prostate cancer, %HGTV and %TV did not improve prediction of early BCR after RP substantially, although %HGTV was an independent predictor of early BCR. Therefore, sophisticated TV/HGTV measurements do not seem to have additional benefit for early BCR prediction relative to the use of Gleason grading. However, these results need to be confirmed in larger, prospective studies. © 2013 The Authors. BJU International © 2013 BJU International.

Objectives: The contemporary ability of prostate -specific antigen (PSA) to predict pathologic stage in men with localized prostate cancer was recently questioned. Methods: We quantified the added value related to the addition of pretreatment PSA to established pathologic stage predictors (namely clinical stage and biopsy Gleason sum) in 5921 consecutive radical prostatectomy (RP) patients. Univariable and multivariable logistic regression analyses predicting pathologic stage (extracapsular extension [ECE], seminal vesicle invasion [SVI], lymph node invasion [LNI], and organ-confined disease [OC]) were stratified according to four time quartiles. The gain in predictive accuracy (PA) related to the inclusion of PSA to multivariable models was quantified by using the area under the curve method. Results: Temporal analyses showed a decrease in PSA levels over the study years (p < 0.001). Conversely, the rate of nonpalpable disease and the rate of biopsy Gleason sum < 6 increased over time (all p < 0.001). At RP, the rate of OC increased over time, while the rate of ECE and SVI decreased over time (all p < 0.001). The rate of LNI remained stable (p = 0.1). In multivariable models, PSA represented an independent predictor of all pathologic stages over time (all p < 0.03), except for ECE in the first and last time quartiles. The addition of PSA significantly increased the multivariable PA of all models predicting pathologic stages over time (all p < 0.03), except for ECE predictions in the first quartile (p = 0.1). Conclusions: In the new millennium, PSA has not lost its ability to accurately predict the pathologic stage in contemporary patients.

Background The European Association of Urology (EAU) non–muscle-invasive bladder cancer (NMIBC) guidelines are meant to help minimise morbidity and improve the care of patients with NMIBC. However, there may be underuse of guideline-recommended care in this potentially curable cohort. Objective To assess European physicians' current practice in the management of NMIBC and evaluate its concordance with the EAU 2013 guidelines. Design, setting, and participants Initial 45-min telephone interviews were conducted with 20 urologists to develop a 26-item questionnaire for a 30-min online quantitative interview. A total of 498 physicians with predefined experience in treatment of NMIBC patients, from nine European countries, completed the online interviews. Outcome measurements and statistical analysis Descriptive statistics of absolute numbers and percentages of the use of diagnostic tools, risk group stratification, treatment options chosen, and follow-up regimens were used. Results and limitations Guidelines are used by ≥87% of physicians, with the EAU guidelines being the most used ones (71–100%). Cystoscopy (60–97%) and ultrasonography (42–95%) are the most used diagnostic techniques. Using EAU risk classification, 40–69% and 88–100% of physicians correctly identify all the prognostic factors for low- and high-risk tumours, respectively. Re-transurethral resection of the bladder tumour (re-TURB) is performed in 25–75% of low-risk and 55–98% of high-risk patients. Between 21% and 88% of patients received a single instillation of chemotherapy within 24h after TURB. Adjuvant intravesical treatment is not given to 6–62%, 2–33%, and 1–20% of the patients with low-, intermediate-, and high-risk NMIBC, respectively. Patients with low-risk NMIBC are likely to be overmonitored and those with high-risk NMIBC undermonitored. Our study is limited by the possible recall bias of the selected physicians. Conclusions Although most European physicians claim to apply the EAU guidelines, adherence to them is low in daily practice. Patient summary Our survey among European physicians investigated discrepancies between guidelines and daily practice in the management of non–muscle-invasive bladder cancer (NMIBC). We conclude that the use of the recommended diagnostic tools, risk-stratification of NMIBC, and performance of re-TURB have been adopted, but adjuvant intravesical treatment and follow-up are not uniformly applied.

Background and Purpose: Sexual dysfunction (SD) is a frequent side effect associated with radical prostatectomy (RP) for prostate cancer (PCa). Some studies have showed the benefit associated with preoperative sexual rehabilitation (prehabilitation) and Enhanced Recovery After Surgery (ERAS) for RP, but no clear clinical recommendations are available yet. Our aim was to conduct a systematic review on sexual prehabilitation prior to RP for patients with a localized PCa and analyze the impact on postoperative sexual health compared with the standard post-operative care.Methods: We performed a systematic review of the literature following the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) recommendations.Results: Four randomized control trials and one retrospective comparative study were included in the analyses. Three of the five studies showed an improved EF recovery post-RP in the prehabilitation group compared to the standard of care represented by: higher International Index of Erectile Function 5 score (IIEF5) or IIEF score (p < 0.0001) and a higher percentage of patients reporting return of EF based on the Sexual Encounter Profile (SEP) (56 vs. 24%, p = 0.007). Self-confidence, therapeutic alliance, and adherence to treatment were stronger for patients with preoperative consultations (p < 0.05) and EF recovery was better in cases of a higher number of follow-up visits (OR 4–5 visits vs. 1:12.19, p = 0.002).Discussion: Despite heterogenous methods and high risks of bias in this systematic review, starting sexual rehabilitation prior to surgery seems to ensure better EF recovery. This prehabilitation should include information of both the patient and his or her partner, with a closer follow up and the use of a multimodal treatment approach that still remains to be defined and validated (oral medication, vacuum devices, pelvic floor muscle training, etc.).

OBJECTIVE: To conduct the first study of intra- and postoperative outcomes related to intraoperative resident involvement in transurethral resection procedures for benign prostatic hyperplasia and bladder cancer in a large, multi-institutional database. DESIGN: Relying on the American College of Surgeons National Surgical Quality Improvement Program Participant User Files (2005-2012), we abstracted all cases of endoscopic prostate surgery (EPS) for benign prostatic hyperplasia and transurethral resection of bladder tumors (TURBTs). Multivariable logistic regression models were constructed to assess the effect of trainee involvement (postgraduate year [PGY] 1-2: junior, PGY 3-4: senior, PGY 5: chief or fellow) vs attending only on operative time and length of hospital stay, as well as 30-day complication, reoperation, and readmission rates. RESULTS: In all, 5093 EPS and 3059 TURBTs for a total of 8152 transurethral resection procedures were performed during the study period for which data on resident involvement were available. In multivariable analyses, resident involvement in EPS or TURBT was associated with increased odds of prolonged operative times and hospital readmissions in 30 days independent of resident level of training. Resident involvement was not associated with overall complications or reoperation rates. CONCLUSIONS: Resident involvement in lower urinary tract surgeries is associated with increased readmissions. Strategies to optimize resident teaching of these common urologic procedures in order to minimize possible risks to patients should be explored. (C) 2015 Association of Program Directors in Surgery.

Introduction: Our goal was to develop and internally validate a nomogram for prediction of lymph node invasion (LNI) in patients with clinically localized prostate cancer undergoing extended pelvic lymphadenectomy (ePLND). Methods: 602 consecutive patients (mean age 65.8 years) underwent an ePLND, where 10 or more nodes were removed. PSA was 1.1-49.9 (median 7.2). Clinical stages were: T1c in 55.6%, T2 in 41.4% and T3 in 3%. Biopsy Gleason sums were: 6 or less in 66%, 7 in 25.4%, 8-10 in 8.6%. Multivariate logistic regression models tested the association between all of the above predictors and LNI. Regression-based coefficients were used to develop a nomogram predicting LNI and 200 bootstrap resamples were used for internal validation. Results: Mean number of lymph nodes removed was 17.1 (range 10-40). LNI was detected in 66 patients (11.0%). Univariate predictive accuracy for total PSA, clinical stage and biopsy Gleason sum was 63%, 58% and 73%, respectively. A nomogram based on clinical stage, PSA and Biopsy Gleason sum demonstrated bootstrap-corrected predictive accuracy of 76%. Conclusions: A nomogram based on pre-treatment PSA, clinical stage and biopsy Gleason sum can highly accurately predict LNI at ePLND. (c) 2006 Elsevier B.V. All rights reserved.

Background: Survival after surgical treatment using competing-risk analysis has been previously examined in patients with prostate cancer (PCa). However, the combined effect of age and comorbidities has not been assessed in patients with high-risk PCa who might have heterogeneous rates of competing mortality despite the presence of aggressive disease. Objective: To examine the risk of 10-yr cancer-specific mortality (CSM) and other-cause mortality (OCM) according to clinical and pathologic characteristics of patients treated with radical prostatectomy (RP) for high-risk PCa. Design, setting, and participants: Within a multi-institutional cohort, 3828 men treated with RP for high-risk PCa (defined as the presence of at least one of these risk factors: prostate-specific antigen >20 ng/ml, biopsy Gleason score 8-10, clinical stage >= T3) were identified. Intervention: All patients underwent RP and pelvic lymph node dissection. Outcome measurements and statistical analysis: Competing-risk Poisson regression analyses were performed to simultaneously assess the 10-yr CSM and OCM rates after RP. The same analyses were also conducted after stratification of patients according to age at surgery, comorbidity status assessed by the Charlson Comorbidity Index (CCI), and number of risk factors (one vs two or more). Results and limitations: Overall, 229 patients (5.9%) died from PCa; 549 (14.3%) died from other causes. The 10-yr CSM and OCM rates ranged from 5.1% to 12.8% and from 4.3% to 37.4%, respectively. Age and CCI were the major determinants of OCM; their impact on CSM was minimal. OCM was the leading cause of death in all patient groups except in young men (

OBJECTIVE To compare the performance and discriminant properties of two instruments (a tree-structured regression model and a logistic regression-based nomogram), recently developed to predict lymph node invasion (LNI) at radical prostatectomy (RP), in a contemporary cohort of European patients. PATIENTS AND METHODS The cohort comprised 1525 consecutive men treated with RP and bilateral pelvic LN dissection (PLND) in two tertiary academic centres in Europe. Clinical stage, pretreatment prostate-specific antigen (PSA) level and biopsy Gleason sum were used to test the ability of the regression tree and the nomogram to predict LNI. Accuracy was quantified by the area under the receiver operating characteristic curve (AUC). All analyses were repeated for each participating institution. RESULTS The AUC for the nomogram was 81%, vs 77% for the regression tree (P = 0.007). When data were stratified according to institution, the nomogram invariably had a higher AUC than the regression tree (Hamburg cohort: nomogram 82.1% vs regression tree 77.0%, P = 0.002; Milan cohort: 82.4% vs 75.9%, respectively; P = 0.03). CONCLUSIONS Nomogram-based predictions of LNI were more accurate than those derived from a regression tree; therefore, we recommend the use of nomogram-derived predictions.

Many investigators suggested that obesity predisposes to adverse prostate cancer characteristics and outcomes. We tested the effect of obesity on the rate of aggressive prostate cancer at either prostate biopsy or radical prostatectomy (RP). Clinical and pathological data were available for 1,814 men. Univariable and multivariable logistic regression models addressed the rate of high grade prostate cancer (HGPCa) at either biopsy or final pathology. Clinical stage, prostate-specific antigen (PSA), percentage of free PSA and prostate volume were the base predictors. All models were fitted with and without body mass index (BMI), which quantified obesity. BMI and its reciprocal (InvBMI) were coded as cubic splines to allow nonlinear effects. Predictive accuracy (PA) was quantified with area under curve estimates, which were subjected to 200 bootstrap resamples to reduce overfit bias. Gains in PA related to the inclusion of BMI were compared using the Mantel-Haenszel test. HGPCa at biopsy was detected in 562 (31%) and HGPCa at RP pathology was present in 931 (51.3%) men. In either univariable or multivariable models predicting HGPCa at biopsy, BMI or InvBMI failed to respectively reach statistical significance or add to multivariable PA (BMI gain =0%, p=1.0; InvBMI gain =-0.2%,p=0.9). Conversely, in models predicting HGPCa at RP, BMI and InvBMI represented independent predictors but failed to increase PA (BMI gain =0.7%, p=0.6; InvBMI gain =0.5, p=0.7%). Obesity does not predispose to more aggressive prostate cancer at biopsy. Similarly, obesity does not change the ability to identify those who may harbor HGPCa at RP. (c) 2007 Wiley-Lissy Inc.

OBJECTIVES To determine whether health-insurance status might result in more localized stage at presentation, more favourable stage at surgery and in a lower rate of biochemical recurrence (BCR), in patients diagnosed with prostate cancer and treated with radical prostatectomy (RP), as despite uninhibited access to healthcare, private and public health insurance are available in most European countries. PATIENTS AND METHODS In all, 4442 consecutive men had RP in two large European centres, of whom 2372 had public and 2070 had private health insurance. The groups were compared for several variables according to insurance status (private vs public). Means and proportions tests were complemented with logistic regression or Kaplan-Meier analyses. RESULTS Serum prostate-specific antigen level (P < 0.001), clinical stage (P < 0.001), pathological Gleason sum (P = 0.02), positive surgical margin rate (18.4% vs 25.4%, P < 0.001), extracapsular extension rate (17.7% vs 20.0%, P = 0.047) and seminal vesicle invasion rate (9.6% vs 11.6%, P = 0.04) were more favourable in privately insured patients. Conversely, the rate of lymph-node involvement was higher in those with private than public insurance (4.4% vs 3.3%, P = 0.045). In univariate analyses addressing pathological variables, private insurance was invariably protective (all P < 0.05). The Kaplan-Meier analyses showed that privately insured patients had a lower rate of BCR after RP (log-rank P = 0.017). CONCLUSION Despite uninhibited access to healthcare, insurance status represents a rate-limiting variable, which affects stage at presentation and the outcome of cancer control.

Objectives: We hypothesized that the number and/or percentage of positive cores, proxies of tumor volume, could improve the ability to predict pathologic stages and/or biochemical recurrence (BCR). To test this hypothesis, we examined radical retropubic prostatectomy (RRP) data from three centers on two continents. Material and methods: Clinical data from men undergoing RRP at three different institutions were used to predict pathologic stages and BCR. Univariable and multivariable logistic analyses and Cox regression analyses were used. Predictive accuracy (PA) was assessed with the area under the receiver operating characteristics curve estimates, which were subjected to 200 bootstraps to reduce overfit bias. The statistical significance of PA gains was assessed with the Mantel-Haenszel test. Results: The number and the percentage of positive cores were independent predictors of virtually all pathologic stage outcomes and of BCR. In PA analyses, the percentage of positive cores improved the PA of pathologic stage predictions and of BCR predictions between 0.06% and 1.49%. Conversely, the number of positive cores improved the PA of pathologic stage predictions and of BCR predictions between 0.36% and 1.14%. Conclusions: The information derived from biopsy cores is important and can improve the ability to predict pathologic stage and BCR. It appears that the percentage of cores is most helpful in stage predictions. Conversely, the number of cores appears to improve mostly BCR predictions. Consideration of both variables might not be helpful because of the similarity of information they encode. (c) 2007 European Association of Urology. Published by Elsevier B.V. All rights reserved.
