Context Low-intensity shockwave therapy (LiST) has emerged as an effective treatment for pain in patients with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS), and it has been postulated that LiST may also be effective in patients with lower urinary tract symptoms (LUTS). Objective To perform a systematic review and meta-analysis of experimental and clinical studies exploring the effect of LiST on LUTS in an attempt to provide clinical implications for future research. Evidence acquisition We systematically searched PubMed, Cochrane Library, and Scopus databases from inception to March 2021 for relevant studies. We provided a qualitative synthesis regarding the role of LiST in LUTS and performed a single-arm, random-effect meta-analysis to assess the absolute effect of LiST on LUTS only in patients with CP/CPPS (PROSPERO: CRD42021238281). Evidence synthesis We included 23 studies (11 experimental studies, seven nonrandomized controlled trials [non-RCTs], and five RCTs) in the systematic review and seven in the meta-analysis. All experimental studies were performed on rats with LUTS, and the clinical studies recruited a total of 539 participants. In patients with CP/CPPS, the absolute effect of LiST on maximum flow rate and postvoid residual was clinically insignificant. However, the available studies suggest that LiST is effective for the management of pain in patients with either CP/CPPS or interstitial cystitis/bladder pain syndrome. Additionally, LiST after intravesical instillation of botulinum neurotoxin type A may enhance its absorption and substitute botulinum neurotoxin type A injections in patients with overactive bladder. Furthermore, the available evidence is inconclusive about the role of LiST in patients with benign prostatic obstruction, stress urinary incontinence, or underactive bladder/detrusor hypoactivity. Conclusions LiST may be effective for some disorders causing LUTS. Still, further studies on the matter are necessary, since the available evidence is scarce. Patient summary Low-intensity shockwave therapy represents a safe, easily applied, indolent, and repeatable on an outpatient basis treatment modality that may improve lower urinary tract symptoms.

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.

Introduction: RC represents a viable treatment option for certain NMIBC patients. However, studies investigating morbidity in the context of RC for NMIBC are scarce. The goal of the current study was to assess and compare morbidity after RC performed in patients with NMIBC and patients with MIBC and to identify risk factors for severe short-term complications. Methods: Medical records of 521 patients who underwent RC for bladder cancer were retrospectively reviewed. Patients were divided into patients with NMIBC and patients with MIBC. The groups were compared and risk factors for severe complications were identified. Results: RC for NMIBC was performed in 123 patients (23.6%). Histological upstaging was seen in 47 NMIBC patients (38.2%) and in 231 MIBC patients (58%, p < 0.001). OS was 29.8% and CSS was 15.5%. Both endpoints were higher for RC for MIBC (p < 0.001). More complications affecting the urinary diversion were seen with RC for NMIBC (p = 0.033) and more continent urinary diversions (p = 0.040) were performed in those patients. Obesity (p = 0.008), a higher ASA score (p = 0.004), and preoperative medical drug anticoagulation (p = 0.025) were risk factors for severe short-term morbidity after both, RC for NMIBC and for MIBC. Conclusion: Patients who underwent RC for NMIBC are exposed to a comparably high perioperative risk than patients with MIBC. RC seems to be a viable treatment option for certain NMIBC patients with a significant histological upstaging in both groups. In patients with obesity, a high ASA score, and with medical drug anticoagulation, the indication for surgery should be confirmed especially strict and possible treatment alternatives should be considered particularly thorough.

To assess the true cumulative morbidity after RC by implementing the Comprehensive Complication Index (CCI) over a 90-day period, since recent evidence suggests underreporting of the cumulative morbidity after radical cystectomy (RC) with inconsistent complication rates when reported with conventional reporting systems.Medical records of 433 patients with bladder cancer who underwent RC were retrospectively reviewed over a 90-day period. Clinical variables were assessed and complications were graded by the Clavien-Dindo Classification (CDC). The resulting 30- and 90-day CCI-scores were calculated and compared for each patient. Multivariable regression models for developing at least one severe (≥CDC IIIb) complication were designed.Overall, 848 complications were recorded in 371 patients (85.7%). Severe complications occurred in 130 patients (30%) and the cumulative morbidity corresponded to the level of a severe complication in 159 patients (36.7%), meaning an upgrade in 6.7% of patients compared to the CDC. The 90-day CCI (24.2 (median, IQR 20.9-39.7)) was higher than the 30-day CCI (22.6 (median, IQR 8.7-39.7)), (p 0.001). Comorbidity indices (ASA, ACE 27), BMI, and incontinent urinary diversions were independent risk factors for suffering a severe complication within 90 days post-surgery.The cumulative morbidity (CCI) after RC seems to be higher than previously reported with CDC, especially over a 90-day period. The CCI is an appropriate assessment-tool with an upgrade in morbidity in a significant proportion of patients when compared to the CDC. BMI, several comorbidity indices, and incontinent urinary diversions are independent risk factors for suffering a severe complication after RC.

BACKGROUND: AQP proteins show a variety of functions in human cell metabolism. The role of different AQP subtypes in tumor metabolism and prognosis are subject of ongoing research. OBJECTIVE: To investigate the mRNA expression of Aquaporin (AQP) 3, 4, 7 and 9 in pT1 non-muscle-invasive bladder cancer (NMIBC) and its prognostic value in therapeutic decision making. METHODS: Formalin-fixed-paraffin-embedded (FFPE) tissues from transurethral resection of the bladder (TURB) from 112 patients with initial diagnosis of stage pT1 NMIBC were analyzed retrospectively together with clinical data and therapeutic approaches. mRNA expression of AQP3, 4, 7 and 9 was measured and quantified using RT-qPCR. RESULTS: Of the 112 patients (83.9%male, median age 72 years), 40 had a recurrence (35.7%), 16 a progression (14.3%) and 14 patients (12.5%) died tumor-related. mRNA expression for AQP3 was detected in 99.1%, AQP4 in 46.4%, AQP7 in 86.6%and AQP9 in 97.3%. Spearman analysis revealed statistically significant correlations between AQP3, AQP7 and AQP9 mRNA expression with adverse clinical and histopathological parameters (WHO1973 grade 3, concomitant Cis or multifocality). High AQP9 mRNA expression was associated with worse PFS in the total cohort (p = 0.034) and in Grade 3 tumors (p = 0.003) in Kaplan-Meier analysis. In patients with bladder sparing approach, high AQP3 mRNA expression was significantly associated with worse CSS in patients receiving BCG therapy (p = 0.029). CONCLUSIONS: mRNA expression of AQP3, 7 and 9 correlates with adverse clinical and pathological parameters. AQP3 and 9 may help to identify a subgroup of highest risk patients who may be considered for early cystectomy.

BACKGROUND VPM1002BC is a genetically modified Mycobacterium bovis bacillus Calmette-Guérin (BCG) strain with potentially improved immunogenicity and attenuation. OBJECTIVE To report on the efficacy, safety, tolerability and quality of life of intravesical VPM1002BC for the treatment of non-muscle-invasive bladder cancer (NMIBC) recurrence after conventional BCG therapy. DESIGN, SETTING, AND PARTICIPANTS We designed a phase 1/2 single-arm trial (NCT02371447). Patients with recurrent NMIBC after BCG induction ± BCG maintenance therapy and intermediate to high risk for cancer progression were eligible. INTERVENTION Patients were scheduled for standard treatment of six weekly instillations with VPM1002BC followed by maintenance for 1 yr. Treatment was stopped in cases of recurrence. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS The primary endpoint was defined as the recurrence-free rate (RFR) in the bladder 60 wk after trial registration. The sample size was calculated based on the assumption that ≥30% of the patients would be without recurrence at 60 wk after registration. RESULTS AND LIMITATIONS After exclusion of two ineligible patients, 40 patients remained in the full analysis set. All treated tumours were of high grade and 27 patients (67.5%) presented with carcinoma in situ. The recurrence-free rate in the bladder at 60 wk after trial registration was 49.3% (95% confidence interval [CI] 32.1-64.4%) and remained at 47.4% (95% CI 30.4-62.6%] at 2 yr and 43.7% (95% CI 26.9-59.4%) at 3 yr after trial registration. At the same time, progression to muscle-invasive disease had occurred in three patients and metastatic disease in four patients. Treatment-related grade 1, 2, and 3 adverse events (AEs) were observed in 14.3%, 54.8%, and 4.8% of the patients, respectively. No grade ≥4 AEs occurred. Two of the 42 patients did not tolerate five or more instillations during induction. Limitations include the single-arm trial design and the low number of patients for subgroup analysis. CONCLUSIONS At 1 yr after treatment start, almost half of the patients remained recurrence-free after therapy with VPM100BC. The primary endpoint of the study was met and the therapy is safe and well tolerated. PATIENT SUMMARY We conducted a trial of VPM100BC, a genetically modified bacillus Calmette-Guérin (BCG) strain for treatment of bladder cancer not invading the bladder muscle. At 1 year after the start of treatment, almost half of the patients with a recurrence after previous conventional BCG were free from non-muscle-invasive bladder cancer (NMIBC). The results are encouraging and VPM1002BC merits further evaluation in randomised studies for patients with NMIBC.

Tumor budding is defined as a single cell or a cluster of up to 5 tumor cells at the invasion front. Due to the difficulty of identifying patients at high risk for pT1 non-muscle-invasive bladder cancer (NMIBC) and the difficulties in T1 substaging, tumor budding was evaluated as a potential alternative and prognostic parameter in these patients. Tumor budding as well as growth pattern, invasion pattern and lamina propria infiltration were retrospectively evaluated in transurethral resection of the bladder (TURB) specimens from 92 patients with stage pT1 NMIBC. The presence of tumor budding correlated with multifocal tumors (p = 0.003), discontinuous invasion pattern (p = 0.039), discohesive growth pattern (p p p = 0.005), PFS (p = 0.017) and CSS (p = 0.002). In patients who received BCG instillation therapy (n = 65), the absence of tumor budding was associated with improved RFS (p = 0.012), PFS (p = 0.011) and CSS (p = 0.022), with none of the patients suffering from progression or dying from the disease. Tumor budding is associated with a more aggressive and invasive stage of pT1 NMIBC and a worse outcome. This easy-to-assess parameter could help stratify patients into BCG therapy or early cystectomy treatment groups.

Purpose Photodynamic diagnosis and white-light TURB with adjuvant intravesical chemotherapy (ICT) is widely used in treatment of bladder cancer. This non-inferiority trial is designed to demonstrate non-inferiority regarding recurrence-free survival (RFS) of Hexvix® TURB followed by immediate instillation compared to white-light TURB with immediate instillation followed by maintenance ICT. Methods Between 07/2010 and 12/2016, 129 patients with EORTC intermediate risk non-muscle invasive bladder cancer treated with TURB were included in this multicentre phase III study. Patients were randomized and received either white-light TURB with immediate ICT followed by maintenance ICT (n = 62, 20 mg Mitomycin weekly for 6 weeks as induction phase, afterwards 20 mg/month for 6 months) or Hexvix® TURB with immediate ICT only (n = 67, 40 mg Mitomycin). Primary study endpoint was RFS after 12 months. Hexvix® TURB was counted as non-inferior to white light alone if the upper limit of the one-sided 95% confidence interval of hazard ratio was lower than 1.676. Due to the non-inferiority design, the per-protocol population was used as the primary analysis population (n = 113) Results Median follow-up was 1.81 years. Hexvix® group showed more events (recurrence or death) than white-light group (19 vs. 10) resulting in a HR of 1.29 (upper limit of one-sided 95%-CI = 2.45; pnon-inferiority = 0.249). The ITT population yielded similar results (HR = 1.67); 3.18], pnon-inferiority = 0.493). There was no significant difference in overall survival between both groups (p = 0.257). Conclusion Non-inferiority of Hexvix® TURB relative to white-light TURB with maintenance Mitomycin instillation in intermediate risk urothelial carcinoma of the bladder was not proven. Hence a higher effect of maintenance ICT is to assume compared to a Hexvix®-improved TURB only, confirming its important role in patient treatment.

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

A single-center study was conducted to investigate the impact of sarcopenia as a predictor for 90-day mortality (90 dM) and complications within 90 days after radical cystectomy for bladder cancer. In total, 327 patients with preoperative available digital computed tomography (CT) scans of the abdomen and pelvis were identified. The lumbar skeletal muscle index was measured using preoperative abdominal CT to assess sarcopenia. Complications were recorded and graded according to Clavien–Dindo (CD). Predictors of 90 dM and complications within 90 days were analyzed by uni- and multivariable logistic regression. Of the 327 patients, 262 (80%) were male and 108 (33%) patients were classified as sarcopenic. Within 90 days, 28 (7.8%) patients died, of whom 15 patients were sarcopenic and 13 were not. In multivariable logistic regression analysis, sarcopenia (OR 2.59; 95% CI 1.13–5.95; p = 0.025), ASA 3–4 (OR 2.53; 95% CI 1.10–5.82; p = 0.029) and cM + (OR 7.43; 95% CI 2.34–23.64; p = 0.001) were independent predictors of 90-day mortality. Sarcopenic patients experienced significantly more complications, i.e., CD 4a–5 (p = 0.003), compared to non-sarcopenic patients. In multivariable logistic regression analysis, sarcopenia was independently associated with CD ≥ 3b complications corrected for age, BMI, ASA-Score and type of urinary diversion. We reported that sarcopenia proved an independent predictor for 90 dM and complications in patients undergoing RC for bladder cancer.

Zusammenfassung Einleitung In den letzten Jahrzehnten ist eine steigende Inzidenz des Nierenzellkarzinoms zu beobachten. Bedingt durch die verbesserten bildgebenden Verfahren und deren häufigeren Einsatz kommt es gleichzeitig zu einer vermehrten Diagnose kleiner Tumoren im Stadium pT1. Es ist jedoch bekannt, dass auch kleine Nierentumore spät rezidivieren und metastasieren können. Die Fragestellung der vorliegenden Studie ist es, unkompliziert zu erhebende klinische und histopathologische Faktoren für die Prognoseeinschätzung kleiner Nierentumore zu identifizieren. Patienten/Methoden Es erfolgte die retrospektive Analyse aller Patienten, die im Zeitraum zwischen 1993 – 2007 an einem Einzelzentrum aufgrund eines pT1-Nierenzellkarzinoms operiert wurden. Klinische und histopathologische Parameter wurden hinsichtlich ihres Einflusses auf das Rezidiv-freie Überleben (RFS), Karzinom-spezifische Überleben (CSS) und das Gesamtüberleben (OS) mittels Kaplan-Meier-Analyse, univariater und multivariater Cox-Regressionsanalyse untersucht. Ergebnisse Insgesamt konnten die Daten von 571 Patienten erhoben werden. Das mediane Follow-up betrug 111 Monate. Die Rezidivrate betrug 7,2 %, 15 % der Rezidive traten nach über 10 Jahren auf. Bezogen auf das RFS zeigten sich höheres Grading (p = 0,031) und Stadium pT1b (p In der multivariaten Analyse zeigte sich das Stadium pT1b als einziger prädiktiver Faktor für ein schlechteres RFS (p = 0,001) und CSS (p = 0,009). Hinsichtlich des Gesamtüberlebens waren Multifokalität (p = 0,041) und das Vorhandensein eines Diabetes mellitus (p Schlussfolgerung Die beschriebenen prognostischen Parameter können helfen, die Nachsorge von Patienten mit kleinen Nierentumoren risikoadaptiert anzupassen.

Background: Cancer/testis antigens (CTA) are expressed in urothelial bladder cancer (UBC). Their therapeutical and prognostic relevance remains unclear. We studied the correlation of MAGEA3 and CTAG1B with histopathological factors in UBC and their prognostic value. Methods: Retrospective analysis of 93 patients who underwent treatment for UBC was conducted. Besides clinical and histopathological parameters, the expression of MAGEA3 and CTAG1B was assessed by immunohistochemistry. Results: Median follow-up was 75 months. Fifteen per cent of patients showed strong positive reaction to MAGEA3 staining. These tumours were statistically and significantly more often correlated with unfavourable World Health Organization (WHO) grading (G1: 0%, G2: 10.3%, G3: 23.4%, p = 0.048; low grade 0%, high grade 18.4%, p = 0.046 respectively). Correlation of CTAG1B with WHO grading was impressive with strong expression in no G1, 31.1% of G2 and 51.1% of G3 tumours (low grade 0%, high grade 43.4%, p = 0.001, respectively). Concomitant carcinoma in situ (Cis) was associated with strong CTAG1B expression (54.2% in concomitant Cis vs. 29% without concomitant Cis, p = 0.026). Kaplan-Meier analysis revealed statistically and significantly worse 5 years progression-free survival (PFS) associated with a strong expression of MAGEA3 (59 vs. 84%, p = 0.032). Conclusions: Strong CTA expression was correlated with unfavourable histopathological features. A strong expression of MAGEA3 was statistically and significantly associated with worse PFS across all stages of UBC.

BACKGROUND Urothelial carcinoma of the bladder (UBC) at stage pT1 is a heterogenous disease. Established criteria for prognosis prediction are not suitable for every patient. Choosing the right therapeutic strategy for the individual patient thus remains a challenge. The aim of the present study was to identify clinical parameters regarding cancer-specific survival (CSS) in patients with pT1 UBC. MATERIALS AND METHODS A retrospective analysis of clinical parameters of all patients with a pT1 UBC between 1989 and 2012 from a single centre was performed. Treatment consisted of transurethral resection, second resection followed by initially bladder sparing treatment. Anamnestic data, histopathological reports and clinical course were assessed with CSS being defined as primary endpoint. Kaplan-Meier analysis, uni- and multivariate analysis were performed using SPSS (Version 22, IBM). RESULTS 378 patients (78% male, median age 72 years) were included, median follow-up was 35 months. Pathological stage pT1G3 (66 vs. 91%, p

Radical cystectomy (RC) for urothelial carcinoma of the bladder (UCB) is associated with heterogeneous functional and oncological outcomes. The aim of this study was to generate trifecta and pentafecta criteria to optimize outcome reporting after RC. We interviewed 50 experts to consider a virtual group of patients (age ≤ 75 years, ASA score ≤ 3) undergoing RC for a cT2 UCB and a final histology of ≤pT3pN0M0. A ranking was generated for the three and five criteria with the highest sum score. The criteria were applied to the Prospective Multicenter Radical Cystectomy Series 2011. Multivariable binary logistic regression analyses were used to evaluate the impact of clinical and histopathological parameters on meeting the top selected criteria. The criteria with the highest sum score were negative soft tissue surgical margin, lymph node (LN) dissection of at least 16 LNs, no complications according to Clavien–Dindo grade 3–5 within 90 days after RC, treatment-free time between TUR-BT with detection of muscle-invasive UCB and RC

Background/Aims/Objectives: To evaluate the influence of body mass index (BMI) on complications and oncological outcomes in patients undergoing radical cystectomy (RC). Methods: Clinical and histopathological parameters of patients have been prospectively collected within the “PROspective MulticEnTer RadIcal Cystectomy Series 2011”. BMI was categorized as normal weight (2), overweight (≥25–29.9 kg/m2) and obesity (≥30 kg/m2). The association between BMI and clinical and histopathological endpoints was examined. Ordinal logistic regression models were applied to assess the influence of BMI on complication rate and survival. Results: Data of 671 patients were eligible for final analysis. Of these patients, 26% (n = 175) showed obesity. No significant association of obesity on tumour stage, grade, lymph node metastasis, blood loss, type of urinary diversion and 90-day mortality rate was found. According to the ­American Society of Anesthesiologists score, local lymph node (NT) stage and operative case load patients with higher BMI had significantly higher probabilities of severe complications 30 days after RC (p = 0.037). The overall survival rate of obese patients was superior to normal weight patients (p = 0.019). Conclusions: There is no evidence of correlation between obesity and worse oncological outcomes after RC. While obesity should not be a parameter to exclude patients from cystectomy, surgical settings need to be aware of higher short-term complication risks and obese patients should be counselled ­accordingly.

To evaluate the effect of peri-operative blood transfusion (PBT) on recurrence-free survival, overall survival, cancer-specific mortality and other-cause mortality in patients undergoing radical cystectomy (RC), using a contemporary European multicentre cohort.The Prospective Multicentre Radical Cystectomy Series (PROMETRICS) includes data on 679 patients who underwent RC at 18 European tertiary care centres in 2011. The association between PBT and oncological survival outcomes was assessed using Kaplan-Meier, Cox regression and competing-risks analyses. Imbalances in clinicopathological features between patients receiving PBT vs those not receiving PBT were mitigated using conventional multivariable adjusting as well as inverse probability of treatment weighting (IPTW).Overall, 611 patients had complete information on PBT, and 315 (51.6%) received PBT. The two groups (PBT vs no PBT) differed significantly with respect to most clinicopathological features, including peri-operative blood loss: median (interquartile range [IQR]) 1000 (600-1500) mL vs 500 (400-800) mL (P0.001). Independent predictors of receipt of PBT in multivariable logistic regression analysis were female gender (odds ratio [OR] 5.05, 95% confidence interval [CI] 2.62-9.71; P0.001), body mass index (OR 0.91, 95% CI 0.87-0.95; P0.001), type of urinary diversion (OR 0.38, 95% CI 0.18-0.82; P = 0.013), blood loss (OR 1.32, 95% CI 1.23-1.40; P0.001), neoadjuvant chemotherapy (OR 2.62, 95% CI 1.37-5.00; P = 0.004), and ≥pT3 tumours (OR 1.59, 95% CI 1.02-2.48; P = 0.041). In 531 patients with complete data on survival outcomes, unweighted and unadjusted survival analyses showed worse overall survival, cancer-specific mortality and other-cause mortality rates for patients receiving PBT(P0.001, P = 0.017 and P = 0.001, respectively). After IPTW adjustment, those differences no longer held true. PBT was not associated with recurrence-free survival (hazard ratio [HR] 0.92, 95% CI 0.53-1.58; P = 0.8), overall survival (HR 1.06, 95% CI 0.55-2.05; P = 0.9), cancer-specific mortality (sub-HR 1.09, 95% CI 0.62-1.92; P = 0.8) and other-cause mortality (sub-HR 1.00, 95% CI 0.26-3.85; P0.9) in IPTW-adjusted Cox regression and competing-risks analyses. The same held true in conventional multivariable Cox and competing-risks analyses, where PBT could not be confirmed as a predictor of any given endpoint (all P values0.05).The present results did not show an adverse effect of PBT on oncological outcomes after adjusting for baseline differences in patient characteristics.

Background Case volume has been suggested to affect surgical outcomes in different arrays of procedures. We aimed to delineate the relationship between case volume and surgical outcomes and quality of care criteria of radical cystectomy (RC) in a prospectively collected multicenter cohort. Patients and Methods This was a retrospective analysis of a prospectively collected European cohort of patients with bladder cancer treated with RC in 2011. We relied on 479 and 459 eligible patients with available information on hospital case volume and surgeon case volume, respectively. Hospital case volume was divided into tertiles, and surgeon volume was dichotomized according to the median annual number of surgeries performed. Binomial generalized estimating equations controlling for potential known confounders and inter-hospital clustering assessed the independent association of case volume with short-term complications and mortality, as well as the fulfillment of quality of care criteria. Results The high-volume threshold for hospitals was 45 RCs and, for high-volume surgeons, was > 15 cases annually. In adjusted analyses, high hospital volume remained an independent predictor of fewer 30-day (odds ratio, 0.34; P = .002) and 60- to 90-day (odds ratio, 0.41; P = .03) major complications but not of fulfilling quality of care criteria or mortality. No difference between surgeon volume groups was noted for complications, quality of care criteria, or mortality after adjustments. Conclusion The coordination of care at high-volume hospitals might confer a similar important factor in postoperative outcomes as surgeon case volume in RC. This points to organizational elements in high-volume hospitals that enable them to react more appropriately to adverse events after surgery.

Living kidney donation (LKD) involves little risk for the donor and provides excellent functional outcome for transplant recipients. However, contradictory data exist on the incidence and degree of impaired renal function (IRF) in the donor. Only few studies compared the incidence of IRF in donors with that of patients having undergone radical nephrectomy (RN). From 1992 to 2012, 94 healthy subjects underwent an open nephrectomy for living kidney donation at the University Medical Center of Wurzburg. These patients were compared with matched subjects who had the same surgical procedure for renal cell carcinoma at the Carl-Thiem Hospital Cottbus (1:1 matching using propensity scores). In the LKD-group, no complication ≥ Grade 3 according to the Clavien–Dindo classification occurred. Donors had a preoperative median estimated glomerular filtration rate (eGFR) of 85.1 ml/min which changed to 54.4, 57.0 and 61.0 ml/min (all p

Shock wave lithotripsy (SWL) is the gold standard for the treatment of upper urinary tract stones. Despite being relatively non-invasive, SWL can cause renal hematoma (RHT). The aim of this study was to determine incidence and risk factors for RHT following SWL. 857 patients were included in a prospectively maintained database. The observation period spans from 2007 to 2012. 1,324 procedures were performed due to kidney stones. Treatment protocol included power ramping and shock wave frequency of 60-90 per minute as well as an ultrasound check within 3 days of SWL for all patients. Patients with RHT were analyzed, and treatment characteristics were compared with the complete population in a non-statistical manner due to the low event count. RHTs after SWL, sized between 2.6 × 0.6 cm and 17 × 15 cm, were verified in seven patients (0.53%). In four patients, the RHT was asymptomatic. Three patients developed pain after SWL treatment due to a RHT. In one patient surgical intervention was necessary due to a symptomatic RHT, the kidney was preserved. The risk of RHT following SWL treatment of kidney stones is about 0.5%. Clinically relevant or symptomatic RHTs occur in 0.23%, RHTs requiring surgical intervention are extremely rare. Older age and vascular comorbidities appear to be risk factors for the development of RHT. The technical characteristics of SWL treatment and intake of low-dose acetylsalicylic acid due to an imperative cardiologic indication do not appear to influence the risk. Prospective studies are warranted.

Radical cystectomy (RC) and pelvic lymph node dissection (LND) are standard treatments for muscle-invasive urothelial carcinoma of the bladder. Lymph node staging is a prerequisite for clinical decision-making regarding adjuvant chemotherapy and follow-up regimens. Recently, the clinical and pathological nodal staging scores (cNSS and pNSS) were developed. Prior to RC, cNSS determines the minimum number of lymph nodes required to be dissected; pNSS quantifies the accuracy of negative nodal staging based on pT stage and dissected LNs. cNSS and pNSS have not been externally validated, and their relevance for prediction of cancer-specific mortality (CSM) has not been assessed. In this retrospective study of 2,483 RC patients from eight German centers, we externally validated cNSS and pNSS and determined their prediction of CSM. All patients underwent RC and LND. Median follow-up was 44 months. cNSS and pNSS sensitivities were evaluated using the original beta-binominal models. Adjusted proportional hazards models were calculated for pN0 patients to assess the predictive value of cNSS and pNSS for CSM. cNSS and pNSS both pass external validation. Adjusted for other clinical parameters, cNSS can predict outcome after RC. pNSS has no independent impact on prediction of CSM. The retrospective design is the major limitation of the study. In the present external validation, we confirm the validity of both cNSS and pNSS. cNSS is an independent predictor of CSM, thus rendering it useful as a tool for planning the extent of LND.

Introduction Guidelines recommend neoadjuvant chemotherapy (NAC) before radical cystectomy (RC) in patients with urothelial carcinoma of the bladder in clinical stages T2-T4a, cN0M0. We examined the frequency and current practice of NAC and sought to identify predictors for the use of NAC in a prospective contemporary cohort. Materials and Methods We analyzed prospective data from 679 patients in the PROMETRICS (PROspective MulticEnTer RadIcal Cystectomy Series 2011) database. All patients underwent RC in 2011. Uni- and multivariable regression analyses identified predictors of NAC application. Furthermore, a questionnaire was used to evaluate the practice patterns of NAC at the PROMETRICS centers. Results A total of 235 patients (35%) were included in the analysis. Only 15 patients (2.2%) received NAC before RC. Younger age ( P = .035), lower case volume of the center ( P P = .038) were identified as predictors for NAC. Of the 200 urologists who replied to the questionnaire, 69% (n = 125) declared tumor stage cT3-4 a/o N1M0 to be the best indication for NAC application, although 45% of the urologists stated that they would not perform NAC despite recommendations. The decision for NAC was made by the individual urologist in 69% of cases, and only 29% reported that all cases were discussed in an interdisciplinary tumor board. Conclusion NAC was rarely applied in the present cohort. We observed a discrepancy between guideline recommendations and practice patterns, despite medical indication and pre-therapeutic interdisciplinary discussion. The potential benefit of NAC within a multimodal approach seems to be neglected by many urologists.

Background The benefit of adjuvant chemotherapy (AC) for muscle-invasive urothelial carcinoma of the bladder (UCB) after radical cystectomy (RC) is controversial. Objective To assess the effectiveness of AC after RC for muscle-invasive UCB in contemporary European routine practice. Design, setting, and participants By using a prospectively collected European multicenter database, we compared survival outcomes between patients who received AC versus observation after RC for locally advanced (pT3/T4) and/or pelvic lymph node–positive (pN+) muscle-invasive UCB in 2011. Intervention AC versus observation after RC. Outcome measurements and statistical analysis Inverse probability of treatment weighting (IPTW)–adjusted Cox regression and competing risks analyses were performed to compare overall survival (OS) as well as cancer-specific and other-cause mortality between patients who received AC versus observation. Results and limitations Overall, 224 patients who received AC ( n = 84) versus observation ( n = 140) were included. The rate of 3-yr OS in patients who received AC versus observation was 62.1% versus 40.9%, respectively ( p = 0.014). In IPTW-adjusted Cox regression analysis, AC versus observation was associated with an OS benefit (hazard ratio: 0.47; 95% confidence interval [CI]: 0.25–0.86; p = 0.014). In IPTW-adjusted competing risks analysis, AC versus observation was associated with a decreased risk of cancer-specific mortality (subhazard ratio: 0.51; 95% CI: 0.26–0.98; p = 0.044) without any increased risk of other-cause mortality (subhazard ratio: 0.48; 95% CI: 0.14–1.60; p = 0.233). Limitations include the relatively small sample size as well as the potential presence of unmeasured confounders related to the observational study design. Conclusions We found that AC versus observation was associated with a survival benefit after RC in patients with pT3/T4 and/or pN+ UCB. These results should encourage physicians to deliver AC and researchers to pursue prospective or large observational investigations. Patient summary Overall survival and cancer-specific survival benefit was found in patients who received adjuvant chemotherapy relative to observation after radical cystectomy for locally advanced and/or pelvic lymph node–positive bladder cancer.

Results of a retrospective single-institution study recently suggested improved prognostic outcomes in patients undergoing photodynamic diagnosis (PDD)-assisted transurethral resection of bladder tumor (TURBT) prior to radical cystectomy (RC). We sought to validate the prognostic influence of PDD-assisted TURBT on survival after RC by relying on a multi-institutional dataset. To provide a homogeneous study population, patients with organ metastasis at the time of RC and/or after neoadjuvant chemotherapy were excluded from analysis, which resulted in overall 549 bladder cancer (BC) patients from 18 centers of the Prospective Multicenter Radical Cystectomy Series 2011 (PROMETRICS 2011). To evaluate the influence of PDD conducted during primary or final TURBT on cancer-specific mortality (CSM) and overall mortality (OM) after RC, bootstrap-corrected multivariate Cox proportional-hazards regression models were applied (median follow-up: 25 months; IQR: 19–30). Sensitivity analyses were performed for both patients with pure urothelial carcinoma and patients undergoing one single TURBT only. In 88 (16.0 %) and 100 (18.2 %) patients, PDD was used in primary and final TURBTs, respectively. In 335 (61.0 %) patients, a single TURBT was performed prior to RC; in 194 patients (35.3 %), TURBT had been performed in a different center. CSM and OM rates at 3 years were 32 and 40 %, respectively. Use of PDD during primary or final TURBT was no independent predictor of CSM or OM. These results were internally valid and were confirmed in sensitivity analyses. PDD utilization during TURBT prior to RC does not independently impact the prognosis of BC patients after RC.

To determine whether the immunohistochemical markers survivin and E-cadherin can predict progress at initially diagnosed Ta bladder cancer. We retrospectively searched for every initially diagnosed pTa urothelial bladder carcinoma having been treated at our single-center hospital in Germany from January 1992 up to December 2004. Follow-up was recorded up to June 2010, with recurrence or progress being the endpoints. Immunohistochemical staining and analysis of survivin and E-cadherin of the TURB specimens were performed. Outcome dependency of progression and no progression with immunohistochemical staining was analyzed using uni- and multivariate regression analysis, Kaplan–Meier analysis and uni- and multivariate Cox regression analysis. Overall, 233 patients were included. Forty-two percent of those were tumor free in their follow-up TURBs, 46 % had at least one pTa recurrence and 12 % even showed progress to at least pT1 bladder cancer. Aberrant staining of E-cadherin was found within 71 % of patients with progression in contrast to only 40 % in cases without progression (p = 0.004). Of all progressed patients, 92 % showed overexpression of survivin in their initial pTa specimen compared to 61 % without progression (p = 0.001). Kaplan–Meier analysis revealed aberrant E-cadherin staining to be associated with worse progression-free survival (PFS) (p = 0.005) as well as overexpression of survivin (p = 0.003). In multivariate Cox regression analysis, strong E-cadherin staining was an independent prognosticator for better PFS (p = 0.033) and multifocality (p = 0.046) and tumor size over 3 cm (p = 0.042) were prognosticators for worse PFS. Adding the immunohistochemical markers survivin and E-cadherin could help to identify patients at risk of developing a progressive disease in initial stage pTa bladder cancer.

Rectourinary fistula (RUF) is an uncommon but devastating condition that usually occurs as a complication of surgical treatment or radiotherapy of prostate cancer. Although operative fistula repair remains the most successful treatment, there still is no consensus concerning the management of RUF. We present first experiences and transanal surgical technique using biological mesh for fistula repair after urological intervention. From January 2009 to December 2013, four cases of RUF were reported at our university hospital. Fistula occurred after extraperitoneal laparoscopic radical prostatectomy, open radical prostatectomy, and high-intensity focused ultrasound, respectively. All patients were initially treated with transanal Cook Biodesign™ mesh, whereas two patients received reoperation with rectal mucosa advancement flap and gracilis muscle flap interposition, respectively. Mean follow-up was 36 months (range 9–62). Fistula diameters ranged from 0.6 to 3.0 cm and were located 5 to 6 cm of anocutaneous line. The time from diagnosis to fistula repair was 3 to 7 weeks. The median operative time for Cook Biodesing™ mesh procedure was 79 min (IQR 60, 98). The initial success rate for biological mesh was 50 % (2/4 patients). Larger fistulae were minimalized successfully and finally closed with reoperation mentioned above. No deterioration of continence was documented. Management of rectourinary fistula is still challenging. Using biomaterials for fistula closure seems to be a promising and minimally invasive transanal technique in future. Further analysis including more patients is needed to clarify its exact role in comparison to traditional surgical techniques.

Radical cystectomy (RC) can be associated with significant blood loss, whereas many patients are presenting with anemia preoperatively. To date, there is a lack of data addressing the impact of preoperative anemia (PA) on survival of patients undergoing RC for urothelial carcinoma of the bladder (UCB).This retrospective multicenter study includes 684 patients with UCB undergoing RC with pelvic lymph node dissection. The median follow-up was 50 (IQR 29,78) months. Anemia was defined in line with the WHO classification (hemoglobin (Hb): male ≤13 g/dL, female ≤12 g/dL) and based on contemporary gender- and age-adjusted classification (Hb: white male aged60 years: ≤13.7 g/dL; ≥60 years: ≤13.2 g/dL; white female of all ages ≤12.2 g/dL). Univariable and multivariable Cox regression analyses were used to assess the effects of PA on oncological outcomes.A total of 269 (39.3 %) and 302 (44.2 %) patients were anemic according to the WHO classification versus contemporary classification. Age, increased ECOG performance status, advanced tumor stages, lymph node metastasis, positive surgical margin and anemia were associated with disease recurrence (DR), cancer-specific mortality (CSM) and all-cause mortality (ACM). In multivariable analysis, anemia was an independent predictor of DR, CSM and ACM (WHO and/or contemporary classification). Blood transfusion was significantly associated with ACM in both classifications of anemia.PA is significantly associated with worse oncological outcome in patients undergoing RC. Based on the additional unfavorable influence of blood transfusion, this emphasizes the importance of early diagnosis and correction of anemia and implementation of alternative methods of blood volume management.

Introduction: We aimed at developing and validating a pre-cystectomy nomogram for the prediction of locally advanced urothelial carcinoma of the bladder (UCB) using clinicopathological parameters. Materials and Methods: Multicenter data from 337 patients who underwent radical cystectomy (RC) for UCB were prospectively collected and eligible for final analysis. Univariate and multivariate logistic regression models were applied to identify significant predictors of locally advanced tumor stage (pT3/4 and/or pN+) at RC. Internal validation was performed by bootstrapping. The decision curve analysis (DCA) was done to evaluate the clinical value. Results: The distribution of tumor stages pT3/4, pN+ and pT3/4 and/or pN+ at RC was 44.2, 27.6 and 50.4%, respectively. Age (odds ratio (OR) 0.980; p < 0.001), advanced clinical tumor stage (cT3 vs. cTa, cTis, cT1; OR 3.367; p < 0.001), presence of hydronephrosis (OR 1.844; p = 0.043) and advanced tumor stage T3 and/or N+ at CT imaging (OR 4.378; p < 0.001) were independent predictors for pT3/4 and/or pN+ tumor stage. The predictive accuracy of our nomogram for pT3/4 and/or pN+ at RC was 77.5%. DCA for predicting pT3/4 and/or pN+ at RC showed a clinical net benefit across all probability thresholds. Conclusion: We developed a nomogram for the prediction of locally advanced tumor stage pT3/4 and/or pN+ before RC using established clinicopathological parameters.

Objective: To analyze gender-specific differences regarding clinical symptoms, referral patterns and tumor biology prior to initial diagnosis of urothelial carcinoma of the bladder (UCB). Methods: A consecutive series of patients with an initial diagnosis of UCB was included. All patients completed a questionnaire on demographics, clinical symptoms and referral patterns. Results: In total, 68 patients (50 men, 18 women) with newly diagnosed UCB at admission for transurethral resection of bladder tumors were recruited. Dysuria was more often observed in women (55.6 vs. 38.0%, p = 0.001). Direct consultation of the urologist was conducted by 84.0% of males and 66.7% of females (p = 0.120). One third of the women saw their general practitioner and/or gynecologist once or twice (p = 0.120) before referral to the urologist. Furthermore, women were significantly more often treated for urinary tract infections than men (61.1 vs. 20.0%, p = 0.005). Cystoscopy at first presentation to the urologist was more often performed in men than women (88.0 vs. 66.7%, p = 0.068), with a more favorable tumor detection rate at first cystoscopy in men (96.0 vs. 50.0%, p < 0.001). Conclusions: Delayed referral patterns might lead to deferred diagnosis of UCB and consequently to adverse outcome. Thus, primary care physicians might consider referring patients with bladder complaints to specialized care earlier.

To externally validate the Christodouleas risk model incorporating pathological tumor stage, lymph node (LN) count and soft tissue surgical margin (STSM) and stratifying patients who develop locoregional recurrence (LR) after radical cystectomy (RC) for urothelial carcinoma of the bladder (UCB). In addition, we aimed to generate a new model including established clinicopathological features that were absent in the Christodouleas risk model. Prospectively assessed multicenter data from 565 patients undergoing RC for UCB in 2011 qualified for final analysis. For the purpose of external validation, risk group stratification according to Christodouleas was performed. Competing-risk models were calculated to compare the cumulative incidences of LR after RC. After a median follow-up of 25 months (interquartile range 19–29), the LR-rate was 11.5 %. The Christodouleas model showed a predictive accuracy of 83.2 % in our cohort. In multivariable competing-risk analysis, tumor stage ≥pT3 (HR 4.32, p

Background and purpose Shockwave lithotripsy (SWL) is the gold standard treatment of patients with most renal and proximal ureteral calculi. Severe bleeding complications in SWL are extremely rare. Uncorrected bleeding diathesis might increase the risk and is considered to be an absolute contraindication for SWL. Perioperative management of anticoagulative and antiplatelet therapy has changed in the recent past. In particular, low-dose acetylsalicylic acid (ASA) is no longer a contraindication for many surgical procedures. Methods A systematic Medline/PubMed literature search of peer-reviewed scientific articles in urology and cardiovascular medicine was performed concerning the management of anticoagulative and antiplatelet medication during SWL. Results The literature on medically acquired and pathological bleeding diathesis and SWL in general is rare, retrospective, nonstandardized, and of low quality. Routine cessation of obligatory indicated anticoagulative or antiplatelet medication implies a significant risk for cardiovascular adverse events (CAE). Ureterorenoscopy is recommended in patients with uncorrected bleeding diathesis, although this is not based on high-level evidence. Conclusion In patients with obligatory intake of anticoagulative or antiplatelet medication, the risk for CAE must be balanced against the SWL-induced bleeding risk. In patients with low-dose ASA-intake, SWL should be considered as an option instead of being disregarded as an absolute contraindication. Prospective randomized trials designed to define the optimal management of anticoagulants and antiplatelets during SWL are warranted.

The aim of this study was to examine preoperative patients’ characteristics associated with the urinary diversion (UD) type (continent vs. incontinent) after radical cystectomy (RC) and UD-associated postoperative complications. In 2011, 679 bladder cancer patients underwent RC at 18 European tertiary care centers. Data were prospectively collected within the ‘PROspective MulticEnTer RadIcal Cystectomy Series 2011’ (PROMETRICS 2011). Logistic regression models assessed the impact of preoperative characteristics on UD type and evaluated diversion-related complication rates. Of 570 eligible patients, 28.8, 2.6, 59.3, and 9.3 % received orthotopic neobladders, continent cutaneous pouches, ileal conduits, and ureterocutaneostomies, respectively. In multivariable analyses, female sex (odds ratio [OR] 3.9; p = 0.002), American Society of Anesthesiologists score ≥3 (OR 2.3; p = 0.02), an age-adjusted Charlson Comorbidity Index ≥3 (OR 4.1; p

Comorbidity and performance indices (CPIs) are useful tools to evaluate patient's risk of comorbidities and thus may guide clinical decision making regarding surgery or multimodal therapy approaches. Hence, the aim of the current study was to assess the predictive capacity of CPIs comprising the American Society of Anaesthesiologists (ASA)-score, the Charlson comorbidity index (CCI), the age-adjusted CCI (ACCI), and the Eastern Cooperative Oncology Group performance status (ECOG-PS) in patients with upper tract urothelial carcinoma (UTUC) who were treated with radical nephroureterectomy (RNU).A total of 242 patients with UTUC underwent RNU without neoadjuvant chemotherapy between 1992 and 2012 at 3 German academic centers. Patients were stratified according to the pre-RNU CPIs dichotomized as ASA 1/2 vs .≥ 3, CCI 0 to 2 vs.2, ACCI 0 to 5 vs.5, and ECOG-PS 0 to 1 vs.1. We assessed the associations of CPIs with clinicopathologic features, as well as the prognostic effect on recurrence-free survival, cancer-specific survival (CSS), overall survival, and cancer-independent mortality (CIM), using univariable and multivariable Cox regression analyses.Sixty-two patients (25.6%) had an ASA-score ≥ 3, 71 patients (29.3%) a CCI2, 50 patients (20.7%) an ACCI5, and 122 (50.4%) patients an ECOG-PS1. The ASA-score (P = 0.001), CCI (P = 0.029), and the ECOG-PS (P0.001) were significantly associated with age. In addition, the ECOG-PS was associated with pelvicalyceal tumors (P = 0.012), and the CCI with preoperative hydronephrosis (P = 0.026). The median follow-up was 30 months. In Kaplan-Meier analyses, ACCI5 (P ≤ 0.025) and ECOG-PS1 (P ≤ 0.042) were associated with recurrence-free survival, CSS, and overall survival, and ASA-score ≥ 3 (P = 0.011) and ACCI5 (P = 0.006) with CIM. In multivariable analysis that adjusted for standard clinicopathologic parameters, an ECOG-PS1 was an independent predictor for CSS (hazard ratio = 1.89, P = 0.019), and an ASA-score ≥ 3 (hazard ratio = 1.86, P = 0.026) was a predictor for CIM.CPIs are easy assessable predictors for outcome in patients with UTUC who were treated with RNU. CPIs have carefully to be taken into account in patient counseling regarding operative decision making and multimodal treatment.

Objective: To identify prognostic clinical and histopathological parameters, including comorbidity indices at the time of radical cystectomy (RC), for overall survival (OS) after recurrence following RC for urothelial carcinoma of the bladder (UCB). Materials and Methods: A retrospective multicenter study was carried out in 555 unselected consecutive patients who underwent RC with pelvic lymph node dissection for UCB from 2000 to 2010. A total of 227 patients with recurrence comprised our study group. Cox proportional hazards regression models were calculated with established variables to assess their independent influence on OS after recurrence. Results: The median time from RC to recurrence and the median OS after recurrence was 10.9 and 5.4 months, respectively. Neither the time to recurrence nor the type of recurrence (systematic vs. local) was predictive of the OS. In contrast, age (hazard ratio (HR) 1.53, p = 0.011), lymph node metastasis (HR 1.56, p = 0.007), and positive surgical margins (HR 1.53, p = 0.046) significantly affected the OS after disease recurrence. In addition, the dichotomized Charlson comorbidity index (CCI; dichotomized into >2 vs. 0-2) was the only comorbidity score with an independent prediction of OS (HR 1.41, p = 0.033). We observed a significant gain in the base model's predictive accuracy, i.e. from 68.4 to 70.3% (p < 0.001), after inclusion of the dichotomized CCI. Conclusions: We present the first outcome study of comorbidity indices used as predictors of OS after disease recurrence in patients undergoing RC for UCB. The CCI at the time of RC had no significant influence on the time to recurrence but represented an independent predictor of OS after disease recurrence., OA-Komponente aus Allianzlizenz

Objective: To investigate the impact of preoperative serum C-reactive protein (CRP) on clinicopathological features and prognosis in patients with upper tract urothelial cancer (UTUC) after radical nephroureterectomy (RNU). Patients andMethods: Data of 265 patients from three German centers who underwent RNU for UTUC without neoadjuvant chemotherapy between 1990 and 2012 were evaluated. Mean follow-up was 37 months (interquartile range 9-48). CRP was analyzed as a categorical and continuous variable for the prediction of recurrence-free survival (RFS), disease-specific survival (DSS) and all-cause survival (ACS) using uni- and multivariate Cox regression analyses. Results: The optimal cutoff for CRP was calculated by the Youden index at 0.90 mg/dl. Elevated CRP was significantly associated with pT3/4 and pN+ in a preoperative model including age, gender, tumor multifocality, tumor localization and the Eastern Cooperative Oncology Group Performance Status. In a multivariable Cox regression model adjusted for features significant in univariable analysis, categorized and continuous CRP levels were both independent predictors for RFS [hazard ratio (HR) 1.18, p = 0.050; HR 1.03, p = 0.012] and DSS (HR 1.61, p = 0.026; HR 1.06, p = 0.001). Continuous CRP was an independent predictor for ACS (HR 1.05, p = 0.036). Conclusions: Elevated preoperative CRP is significantly associated with aggressive tumor biology and an independent predictor for poor survival after RNU. Preoperative serum CRP represents an easily obtainable and cost-effective marker in UTUC and may help in counseling patients with regard to operative management and/or adjuvant or neoadjuvant therapies., OA-Komponente aus Allianzlizenz

Background Despite recent improvements, radical cystectomy (RC) is still associated with adverse rates for 90-d mortality. Objective To validate the performance of the Isbarn nomogram incorporating age and postoperative tumor characteristics for predicting 90-d RC mortality in a multicenter series and to generate a new nomogram based strictly on preoperative parameters. Design, setting, and participants Data of 679 bladder cancer (BCa) patients treated with RC at 18 institutions in 2011 were prospectively collected, from which 597 patients were eligible for final analysis. Intervention RC for BCa. Outcome measurements and statistical analysis An established prediction tool, the Isbarn nomogram, was applied to our cohort. For the purpose of external validation, model discrimination was measured using the receiver operating characteristics–derived area under the curve. Calibration plots examined the relationship between predicted and observed probabilities. Univariable and multivariable logistic regression models were fitted to assess the impact of preoperative characteristics on 90-d mortality. Results and limitations The 30-, 60-, and 90-d mortality rates in the development cohort ( n =597) were 2.7%, 6.7%, and 9.0%, respectively. The Isbarn nomogram predicted individual 90-d mortality with an accuracy of 68.6%. Our preoperative multivariable model identified age (odds ratio [OR]:1.052), American Society of Anesthesiologists score (OR: 2.274), hospital volume (OR: 0.982), clinically lymphatic metastases (OR: 4.111), and clinically distant metastases (OR: 7.788) (all p Conclusions The Isbarn nomogram was validated with moderate discrimination. Our newly developed model consisting of preoperative characteristics might outperform existing models. Our model might be particularly suitable for preoperative patient counseling. Patient summary The current report validated an established nomogram predicting 90-d mortality in patients with bladder cancer after radical cystectomy (RC). We developed a new prediction tool consisting of strictly preoperative parameters, thus allowing clinicians an optimal consultation for RC candidates.
