RESUMEN
PURPOSE: There is no consensus on which items of Enhanced Recovery After Surgery (ERAS) should and should not be implemented in radical cystectomy (RC). The aim of this study is to report current practices across European high-volume RC centers involved in ERAS. METHODS: Based on the recommendations of the ERAS society, we developed a survey with 17 questions that were validated by the Young Academic Urologists-urothelial group. The survey was distributed to European expert centers that implement ERAS for RC. Only one answer per-center was allowed to keep a representative overview of the different centers. RESULTS: 70 surgeons fulfilled the eligibility criteria. Of note, 28.6% of surgeons do not work with a referent anesthesiologist and 25% have not yet assessed the implementation of ERAS in their center. Avoiding bowel preparation, thromboprophylaxis, and removal of the nasogastric tube were widely implemented (> 90%application). On the other hand, preoperative carbohydrate loading, opioid-sparing anesthesia, and audits were less likely to be applied. Common barriers to ERAS implementation were difficulty in changing habits (55%), followed by a lack of communication across surgeons and anesthesiologist (33%). Responders found that performing a regular audit (14%), opioid-sparing anesthesia (14%) and early mobilization (13%) were the most difficult items to implement. CONCLUSION: In this survey, we identified the ERAS items most and less commonly applied. Collaboration with anesthesiologists as well as regular audits remain a challenge for ERAS implementation. These results support the need to uniform ERAS for RC patients and develop strategies to help departments implement ERAS.

PURPOSE OF REVIEW: The role of a re-transurethral resection (TUR) is clearly demonstrated in T1 high-grade nonmuscle invasive bladder cancer. However, its role remains controversial for Ta high-risk tumors and the recent European guidelines stated that the second look procedure could be avoided for these patients despite harboring a high-risk of both disease recurrence and progression. We aimed to evaluate the added benefit on staging, response to bacillus Calmette-Guérin and oncological outcomes of re-TUR in patients with Ta high-grade nonmuscle invasive bladder cancer. RECENT FINDINGS: Overall, we identified 15 studies, including 3912 patients from which 743 harbored Ta high-grade disease. Delay between first and second TUR was ranging from 2 to 12 weeks (median 5.6 weeks). The rate of residual disease was 52.8% (range 17-67%). The rate of overall upstaging to T1 and muscle-invasive disease were 10.9 and 4.7%, respectively. Although there was a trend toward improvement of recurrence-free survival outcomes, no definitive conclusions can be drawn due to the retrospective design of the studies included. SUMMARY: Residual tumor is common after initial TUR for Ta high-grade. Re-TUR is useful in reducing the rates of residual disease, may improve staging, response to bacillus Calmette-Guérin and oncological outcomes.

OBJECTIVES: Adjuvant chemotherapy (ACT) is recommended for non-organ-confined bladder cancer (BCa) after radical cystectomy (RC) and pelvic lymph node dissection (PLND), but there are sparse data regarding its specific efficacy in patients with histological variants. The aim of our study was to evaluate the role of ACT on survival outcomes in patients with variant histology in a large multicenter cohort. MATERIALS AND METHODS: We retrospectively evaluated data of 3963 patients with BCa treated with RC and bilateral PLND with curative intent at several institutions between 1999 and 2018. The histological type was classified into six groups: pure urothelial carcinoma (PUC) or squamous, sarcomatoid, micropapillary, glandular and neuroendocrine differentiation. Multivariable competing risk analysis was applied to assess the role of ACT on recurrence and cancer-specific mortality (CSM) in each histological subtype. RESULTS: Of the 3963 patients included in the study, 23% had variant histology at RC specimen and 723 (18%) patients received ACT. ACT was found to be significantly associated with reduced risk of recurrence (sub-hazard ratio [SHR]: 0.55, confidence interval [CI] 0.42-0.71, p < 0.001) and CSM (SHR: 0.58, CI 0.44-0.78, p < 0.001) in the PUC only, while no histological subtype received a significant benefit on survival outcomes (all p > 0.05) from administration of ACT. The limitation of the study includes the retrospective design, the lack of a central pathology review and the number of ACT cycles. CONCLUSION: In our study, the administration of ACT was associated with improved survival outcomes in PUC only. No histological subtype found a benefit in overall recurrence and CSM from ACT.

PURPOSE: To assess the impact of perioperative chemotherapy on survival in cN+ BCa patients and analyze it according to the pN status. METHODS: A retrospective analysis was conducted on 639 BCa patients with cTanyN1-3M0 BCa treated with radical cystectomy (RC) and bilateral lymph node dissection (LND) with or without perioperative chemotherapy in ten tertiary referral centers from 1990 to 2017. Selected cN+ patients received induction chemotherapy (IC), whereas adjuvant chemotherapy (ACT) was delivered to selected pN+ patients. Univariable and multivariable Cox regression analyses were used to predict overall mortality (OM) after surgery, adjusting for clinicopathological confounders. Kaplan-Meier analyses assessed OM according to the treatment modality. RESULTS: Overall, 356 (56%) patients were treated with surgery alone, 155 (24%) with IC followed by surgery, and 128 (20%) with ACT following surgery. Over a median follow-up of 25 months, 316 deaths were recorded. At univariable analysis, patients treated with IC and surgery had lower OM both considering cN+ [hazard ratio (HR) 0.65, 95% confidence interval (CI) 0.49-0.87, p = 0.004] and cN+pN- patients (HR 0.61, 95% CI 0.37-0.99, p = 0.05) compared to those treated with surgery alone. cN+pN+ patients treated with ACT experienced lower OM compared to those treated with IC or surgery alone at multivariable analysis (HR 0.40, 95% CI 0.22-0.74, p = 0.003). CONCLUSION: Patients with cTany cN+ cM0 BCa benefit more in terms of OS when treated with IC followed by RC + LND compared to RC + LND alone, regardless of LNMs at final histopathology examination. More data are needed to assess the role of ACT in the management of cN+ patients.

PURPOSE: Conflicting evidence exists on the complication rates after cystectomy following previous radiation (pRTC) with only a few available series. We aim to assess the complication rate of pRTC for abdominal-pelvic malignancies. METHODS: Patients treated with radical cystectomy following any previous history of RT and with available information on complications for a minimum of 1 year were included. Univariable and multivariable logistic regression models were used to assess the relationship between the variable parameters and the risk of any complication. RESULTS: 682 patients underwent pRTC after a previous RT (80.5% EBRT) for prostate, bladder (BC), gynecological or other cancers in 49.1%, 27.4%, 9.8% and 12.9%, respectively. Overall, 512 (75.1%) had at least one post-surgical complication, classified as Clavien ≥ 3 in 29.6% and Clavien V in 2.9%. At least one surgical complication occurred in 350 (51.3%), including bowel leakage in 6.2% and ureteric stricture in 9.4%. A medical complication was observed in 359 (52.6%) patients, with UTI/pyelonephritis being the most common (19%), followed by renal failure (12%). The majority of patients (86%) received an incontinent urinary diversion. In multivariable analysis adjusted for age, gender and type of RT, patients treated with RT for bladder cancer had a 1.7 times increased relative risk of experiencing any complication after RC compared to those with RT for prostate cancer (p = 0.023). The type of diversion (continent vs non-continent) did not influence the risk of complications. CONCLUSION: pRTC carries a high rate of major complications that dramatically exceeds the rates reported in RT-naïve RCs.

OBJECTIVES: To compare trends in the use of robot-assisted radical cystectomy (RARC) and changes over time in peri-operative outcomes in selected North American and European centres. MATERIALS AND METHODS: We conducted a retrospective evaluation of 2401 patients treated with open radical cystectomy (ORC) or RARC for bladder cancer at 12 centres in North America and Europe between 2006 and 2018. We used the Kruskal-Wallis and chi-squared test to evaluate differences between continuous and categorical variables. RESULTS: Overall, 49.5% of patients underwent RARC and 51.5% ORC. RARC became the most commonly performed procedure in contemporary patients, with an increase from 29% in 2006-2008 to 54% in 2015-2018 (P < 0.001). In the North American centres the use of RARC was higher than that of ORC from 2006, and remained stable over time, whereas in the European centres its use increased exponentially from 2% to 50%. In both groups patients who underwent RARC had less advanced T stages (P < 0.001), lower American Society of Anesthesiologists scores (P < 0.05), lower blood loss (P = 0.001) and shorter length of hospital stay (P < 0.05). No differences were found in early complications. Early readmission and re-operation rates were worse for patients treated with RARC in the European centres; however, when contemporary patients only were considered, the statistical significance was lost. CONCLUSION: The present study shows that the use of RARC has constantly increased since its introduction, overtaking ORC in the most contemporary series. While RARC was more frequently performed than ORC since its introduction in the North American centres and its use remained substantially stable over time, its use increased exponentially in the European centres. The different trends in use of RARC/ORC and changes over time in peri-operative outcomes between the North American and European centres can be attributed to the earlier introduction and spread of RARC in the former compared with the latter.
RESUMEN
OBJECTIVES: 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. PATIENTS AND METHODS: 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). RESULTS: 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 (P < 0.001). 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; P < 0.001), body mass index (OR 0.91, 95% CI 0.87-0.95; P < 0.001), 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; P < 0.001), 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(P < 0.001, 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; P > 0.9) 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 values >0.05). CONCLUSION: The present results did not show an adverse effect of PBT on oncological outcomes after adjusting for baseline differences in patient characteristics.

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 (<25 kg/m2), 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.

PURPOSE: To evaluate the role of neoadjuvant (NAC) and adjuvant chemotherapy (AC) in patients with upper tract urothelial carcinoma (UTUC) treated with radical nephroureterectomy (RNU). METHODS: A comprehensive review of the current literature was performed searching for all studies investigating NAC and AC in UTUC in MEDLINE and https://clinicaltrials.gov , prior to April 2016. The following keywords were used: "ureteral neoplasms," "urothelium," "ureter," "upper tract urothelial," "chemotherapy," "adjuvant," "neoadjuvant" and relevant variants. RESULTS: No randomized trials investigated the role of AC or NAC for UTUC. There was one prospective study with n = 36 patients investigating AC with carboplatin-paclitaxel. We included 14 retrospective studies (four in the NAC and ten in the AC setting), with a total of 694 patients receiving cisplatin-based or non-cisplatin-based AC after RNU and 1437 patients undergoing RNU alone. We found that the current literature, mainly based on retrospective studies, suggests significant overall and cancer-specific survival benefits for AC in UTUC. NAC appears promising, with favorable pathologic response rates up to 14%. CONCLUSIONS: Evidence is scarce for both NAC and AC use in UTUC. This comprehensive review suggests promising response rates for NAC and a survival benefit for patients treated with AC. Prospective randomized trials are needed to establish the role of AC and NAC in UTUC.

PURPOSE: 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. METHODS: 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. RESULTS: 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. CONCLUSIONS: PDD utilization during TURBT prior to RC does not independently impact the prognosis of BC patients after RC.

OBJECTIVE: To externally validate the pT4a-specific risk model for cancer-specific survival (CSS) proposed by May et al. (Urol Oncol 2013; 31: 1141-1147) and to develop a new pT4a-specific nomogram predicting CSS in an international multicentre cohort of patients undergoing radical cystectomy (RC) for urothelial carcinoma of the bladder (UCB) PATIENTS AND METHODS: Data from 856 patients with pT4a UCB treated with RC at 21 centres in Europe and North-America were assessed. The risk model proposed by May et al., which includes female gender, presence of positive lymphovascular invasion (LVI) and lack of adjuvant chemotherapy administration as adverse predictors for CSS, was applied to our cohort. For the purpose of external validation, model discrimination was measured using the receiver-operating characteristic-derived area under the curve. A nomogram for predicting CSS in pT4a UCB after RC was developed after internal validation based on multivariable Cox proportional hazards regression analysis evaluating the impact of clinicopathological variables on CSS. Decision-curve analyses were applied to determine the net benefit derived from the two models. RESULTS: The estimated 5-year-CSS after RC was 34% in our cohort. The risk model devised by May et al. predicted individual 5-year-CSS with an accuracy of 60.1%. In multivariable Cox proportional hazards regression analysis, female gender (hazard ratio [HR] 1.45), LVI (HR 1.37), lymph node metastases (HR 2.54), positive soft tissue surgical margins (HR 1.39), neoadjuvant (HR 2.24) and lack of adjuvant chemotherapy (HR 1.67, all P < 0.05) were independent predictors of an adverse CSS rate and formed the features of our nomogram with a predictive accuracy of 67.1%. Decision-curve analyses showed higher net benefits for the use of the newly developed nomogram in our cohort over all thresholds. CONCLUSIONS: The risk model devised by May et al. was validated with moderate discrimination and was outperformed by our newly developed pT4a-specific nomogram in the present study population. Our nomogram might be particularly suitable for postoperative patient counselling in the heterogeneous cohort of patients with pT4a UCB.

PURPOSE: To determine whether the immunohistochemical markers survivin and E-cadherin can predict progress at initially diagnosed Ta bladder cancer. METHODS: 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. RESULTS: 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. CONCLUSION: 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.

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.

PURPOSE: 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. MATERIALS: 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. RESULTS: 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 < 0.001), and a positive biopsy of the prostatic urethra in the last transurethral resection of the bladder prior to RC (OR 4.9; p = 0.03) were independently associated with incontinent UD. There were no significant differences in 30- and/or 90-day complication rates between the UD types. Perioperative transfusion rates and 90-day mortality were significantly associated with incontinent UD (p < 0.001, respectively). Limitations included the small sample size and a certain level of heterogeneity in the application of clinical pathways between the different participating centers. CONCLUSIONS: Within this prospective contemporary cohort of European RC patients treated at tertiary care centers, the majority of patients received an incontinent UD. Female sex and pre-existing comorbidities were associated with receiving an incontinent UD. The risk of overall complications did not vary according to UD type.

PURPOSE: 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. METHODS: 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. RESULTS: 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 < 0.001), positive STSM (HR 2.93, p = 0.005), lymphovascular invasion (HR 3.41, p < 0.001), the number of removed LNs <10 (HR 2.62, p < 0.001) and the administration of adjuvant chemotherapy (HR 0.40, p = 0.008) independently predicted the LR-rate. The resulting risk groups revealed significant differences in LR-rates after 24 months with 4.8 % for low-risk patients, 14.7 % for intermediate-risk patients and 38.9 % for high-risk patients (p < 0.001 for all), with a predictive accuracy of 85.6 %, respectively. CONCLUSIONS: The Christodouleas risk model has been successfully externally validated in the present prospective series. However, this analysis finds that overall model performance may be improved by incorporating lymphovascular invasion. After external validation of the newly proposed risk model, it may be used to identify patients who benefit from an adjuvant therapy and suit for inclusion in clinical trials.

UNLABELLED: 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. METHODS: 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. RESULTS: 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 <3 months and the absence of local UCB-recurrence in the pelvis ≤12 months. The first three criteria formed trifecta, and all five criteria pentafecta. A total of 334 patients qualified for final analysis, whereas 35.3 and 29 % met trifecta and pentafecta criteria, respectively. Multivariable analyses showed that the relative probability of meeting trifecta and pentafecta decreases with higher age (3.2 %, p = 0.043 and 3.3 %, p = 0.042) per year, respectively. CONCLUSIONS: Trifecta and pentafecta incorporate essential criteria in terms of outcome reporting and might be considered for the improvement of standardized quality assessment after RC for UCB.

PURPOSE: To evaluate for the first time the prognostic significance of female invasive patterns in stage pT4a urothelial carcinoma of the bladder in a large series of women undergoing anterior pelvic exenteration. PATIENTS AND METHODS: Our series comprised of 92 female patients in total of whom 87 with known invasion patterns were eligible for final analysis. Median follow-up for evaluation of cancer-specific mortality (CSM) was 38 months (interquartile ranges, 21-82 months). The impact on CSM was evaluated using multivariable Cox proportional-hazards regression analysis; predictive accuracy (PA) was assessed by receiver operating characteristic analysis. RESULTS: Vaginal invasion was noted in 33 patients (37.9 %; group VAG), uterine invasion in 20 patients (23 %; group UT), and infiltration of both vagina and uterus in 34 patients (39.1 %; group VAG + UT). Groups VAG and UT significantly differed from group VAG + UT with regard to the presence of positive soft tissue margins (STM) only. Five-year-cancer-specific survival probabilities in the groups VAG, UT, and VAG + UT were 21, 20, and 21 %, respectively (p = 0.955). On multivariable analysis, only STM status (HR = 2.02, p = 0.023) independently influenced CSM. C-indices of multivariable models for CSM with and without integration of invasive patterns were 0.570 and 0.567, respectively (PA gain 0.3 %, p = 0.526). CONCLUSIONS: Infiltration of the vagina, the uterus or both is associated with poor 5-year survival rates. With regard to CSM, no difference was detectable between patients with different invasion patterns, thus justifying further collectively including these invasive patterns as stage pT4a.

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.

PURPOSE: We evaluated the impact of preoperative anemia on oncologic outcomes in patients with upper tract urothelial carcinoma treated with radical nephroureterectomy. MATERIALS AND METHODS: A total of 282 patients with upper tract urothelial carcinoma underwent radical nephroureterectomy. Preoperatively measured hemoglobin values were stratified into normal and anemia based on the WHO classification of 13 gm/dl or less and 12 or less considered anemia in males and females, respectively. We performed sensitivity analysis based on contemporary anemia classifications adjusted for the impact of age, gender and race with anemia considered a hemoglobin value of 13.7 gm/dl or less and 13.2 or less in white males younger than 60 and 60 years old or older, respectively, and 12.2 gm/dl or less in white females of all ages. Univariable and multivariable Cox regression analyses were done to assess the effects of anemia on oncologic outcomes. RESULTS: Median preoperative hemoglobin was 13.2 gm/dl (IQR 11.7, 14.3). A total of 112 patients (39.7%) were anemic by the WHO classification vs 129 (45.7%) by the contemporary classification. Anemia was associated with lymph node metastasis, lymphovascular invasion, sessile tumor architecture, tumor necrosis, advanced age and a higher ECOG (Eastern Cooperative Oncology Group) performance score using the WHO and/or the contemporary definition (p ≤0.044). At a median 30-month followup anemia was associated with decreased recurrence-free (p ≤0.008) and cancer specific (p <0.001) survival on Kaplan-Meier analyses. On multivariable analysis adjusted for standard clinicopathological factors anemia remained an independent predictor of disease recurrence (HR 1.76, 95% CI 1.17-2.63 and 1.89, 95% CI 1.26-2.86) and cancer specific mortality (HR 1.88, 95% CI 1.15-3.08 and 2.04, 95% CI 1.21-3.45) by the WHO and contemporary classifications, respectively. CONCLUSIONS: Preoperative anemia is an independent predictor of disease recurrence and cancer specific mortality. It is associated with aggressive tumor features in patients with upper tract urothelial carcinoma treated with radical nephroureterectomy. Hemoglobin is a promising marker for patient counseling and risk stratification for additional treatment decision making.

PURPOSE: We analyzed the distinct clinicopathological features and prognosis of patients with renal cell carcinoma age 40 years or less compared to a reference group of patients 60 to 70 years old. MATERIALS AND METHODS: Overall 2,572 patients retrieved from a multicenter international database comprised of 6,234 patients with surgically treated renal cell carcinoma were included in this retrospective study. Clinical and histopathological features of 297 patients 40 years old or younger (4.8%) were compared to those of 2,275 patients (36.5%) 60 to 70 years old, who served as the reference group. Median followup was 59 months. The impact of young age and further parameters on disease specific mortality and all cause mortality was evaluated by multivariate Cox proportional hazards regression analyses. RESULTS: Young patients more frequently underwent nephron sparing surgery (27% vs 20%, p = 0.008) and regional lymph node dissection compared to older patients (38% vs 32%, p = 0.025). Organ confined tumor stage (81% vs 70%, p <0.001), smaller tumor diameter (4.5 vs 4.7 cm, p = 0.014) and chromophobe subtype (10% vs 4%, p <0.001) were significantly more frequent in young patients. On multivariate analysis older patients had a higher disease specific (HR 2.21, p <0.001) and all cause mortality (HR 3.05, p <0.001). The c indices for the Cox models were 0.87 and 0.78, respectively. However, integration of the variable age group did not significantly increase the predictive accuracy of the disease specific and all cause mortality models. CONCLUSIONS: Young patients with renal cell carcinoma (40 years old or younger) have significantly different frequencies of clinical and histopathological features, and a significantly lower all cause and disease specific mortality compared to patients 60 to 70 years old.
