Item does not contain fulltext, CONTEXT: Treatment of metastatic urothelial carcinoma is currently undergoing a rapid evolution. OBJECTIVE: This overview presents the updated European Association of Urology (EAU) guidelines for metastatic urothelial carcinoma. EVIDENCE ACQUISITION: A comprehensive scoping exercise covering the topic of metastatic urothelial carcinoma is performed annually by the Guidelines Panel. Databases covered by the search included Medline, EMBASE, and the Cochrane Libraries, resulting in yearly guideline updates. EVIDENCE SYNTHESIS: Platinum-based chemotherapy is the recommended first-line standard therapy for all patients fit to receive either cisplatin or carboplatin. Patients positive for programmed death ligand 1 (PD-L1) and ineligible for cisplatin may receive immunotherapy (atezolizumab or pembrolizumab). In case of nonprogressive disease on platinum-based chemotherapy, subsequent maintenance immunotherapy (avelumab) is recommended. For patients without maintenance therapy, the recommended second-line regimen is immunotherapy (pembrolizumab). Later-line treatment has undergone recent advances: the antibody-drug conjugate enfortumab vedotin demonstrated improved overall survival and the fibroblast growth factor receptor (FGFR) inhibitor erdafitinib appears active in case of FGFR3 alterations. CONCLUSIONS: This 2021 update of the EAU guideline provides detailed and contemporary information on the treatment of metastatic urothelial carcinoma for incorporation into clinical practice. PATIENT SUMMARY: In recent years, several new treatment options have been introduced for patients with metastatic urothelial cancer (including bladder cancer and cancer of the upper urinary tract and urethra). These include immunotherapy and targeted treatments. This updated guideline informs clinicians and patients about optimal tailoring of treatment of affected patients.

Item does not contain fulltext, CONTEXT: This overview presents the updated European Association of Urology (EAU) guidelines for muscle-invasive and metastatic bladder cancer (MMIBC). OBJECTIVE: To provide practical evidence-based recommendations and consensus statements on the clinical management of MMIBC with a focus on diagnosis and treatment. EVIDENCE ACQUISITION: A broad and comprehensive scoping exercise covering all areas of the MMIBC guideline has been performed annually since its 2017 publication (based on the 2016 guideline). Databases covered by the search included Medline, EMBASE, and the Cochrane Libraries, resulting in yearly guideline updates. A level of evidence and a grade of recommendation were assigned. Additionally, the results of a collaborative multistakeholder consensus project on advanced bladder cancer (BC) have been incorporated in the 2020 guidelines, addressing those areas where it is unlikely that prospective comparative studies will be conducted. EVIDENCE SYNTHESIS: Variant histologies are increasingly reported in invasive BC and are relevant for treatment and prognosis. Staging is preferably done with (enhanced) computerised tomography scanning. Treatment decisions are still largely based on clinical factors. Radical cystectomy (RC) with lymph node dissection remains the recommended treatment in highest-risk non-muscle-invasive and muscle-invasive nonmetastatic BC, preceded by cisplatin-based neoadjuvant chemotherapy (NAC) for invasive tumours in "fit" patients. Selected men and women benefit from sexuality sparing RC, although this is not recommended as standard therapy. Open and robotic RC show comparable outcomes, provided the procedure is performed in experienced centres. For open RC 10, the minimum selected case load is 10 procedures per year. If bladder preservation is considered, chemoradiation is an alternative in well-selected patients without carcinoma in situ and after maximal resection. Adjuvant chemotherapy should be considered if no NAC was given. Perio

PURPOSE: The classification of the International Germ-Cell Cancer Collaborative Group (IGCCCG) has been a major advance in the management of germ-cell tumors, but relies on data of only 660 patients with seminoma treated between 1975 and 1990. We re-evaluated this classification in a database from a large international consortium. MATERIALS AND METHODS: Data on 2,451 men with metastatic seminoma treated with cisplatin- and etoposide-based first-line chemotherapy between 1990 and 2013 were collected from 30 institutions or collaborative groups in Australia, Europe, and North America. Clinical trial and registry data were included. Primary end points were progression-free survival (PFS) and overall survival (OS) calculated from day 1 of treatment. Variables at initial presentation were evaluated for their prognostic impact. Results were validated in an independent validation set of 764 additional patients. RESULTS: Compared with the initial IGCCCG classification, in our modern series, 5-year PFS improved from 82% to 89% (95% CI, 87 to 90) and 5-year OS from 86% to 95% (95% CI, 94 to 96) in good prognosis, and from 67% to 79% (95% CI, 70 to 85) and 72% to 88% (95% CI, 80 to 93) in intermediate prognosis patients. Lactate dehydrogenase (LDH) proved to be an additional adverse prognostic factor. Good prognosis patients with LDH above 2.5× upper limit of normal had a 3-year PFS of 80% (95% CI, 75 to 84) and a 3-year OS of 92% (95% CI, 88 to 95) versus 92% (95% CI, 90 to 94) and 97% (95% CI, 96 to 98) in the group with lower LDH. CONCLUSION: PFS and OS in metastatic seminoma significantly improved in our modern series compared with the original data. The original IGCCCG classification retains its relevance, but can be further refined by adding LDH at a cutoff of 2.5× upper limit of normal as an additional adverse prognostic factor.

PURPOSE: The prognostic significance of lactate dehydrogenase (LDH) in patients with metastatic seminoma is not defined. We investigated the prognostic impact of LDH levels prior to first-line systemic treatment and other clinical characteristics in this subset of patients. METHODS: Files from two registry studies and one single-institution database were analyzed retrospectively. Uni- and multivariate analyses were conducted to identify patient characteristics associated with recurrence free survival (RFS), overall survival (OS), and complete response rate (CRR). RESULTS: The dataset included 351 metastatic seminoma patients with a median follow-up of 5.36 years. Five-year RFS, OS and CRR were 82%, 89% and 52%, respectively. Explorative analysis revealed a cut-off LDH level of < 2.5 upper limit of normal (ULN) (n = 228) vs. ≥ 2.5 ULN (n = 123) to be associated with a significant difference concerning OS associated with 5-years OS rates of 93% vs. 83% (p = 0.001) which was confirmed in multivariate analysis (HR 2.87; p = 0.004). Furthermore, the cut-off LDH < 2.5 ULN vs. ≥ 2.5 ULN correlated with RFS and CRR associated with a 5-years RFS rate and CRR of 76% vs. 86% (p = 0.012) and 32% vs. 59% (p ≤ 0.001), respectively. CONCLUSIONS: LDH levels correlate with treatment response and survival in metastatic seminoma patients and should be considered for their prognostic stratification.

Item does not contain fulltext, CONTEXT: In bladder cancer patients treated with radical cystectomy (RC), controversy exists regarding the impact of the annual hospital volume (HV) and/or surgeon volume (SV) on oncological outcomes and quality of care. OBJECTIVE: A systematic review was performed to evaluate the impact of HV and SV on clinical outcomes. Primary outcomes included in-hospital, 30-d, and 90-d mortality. Secondary outcomes included complications, long-term survival, positive surgical margin rate, lymphadenectomy performance, length of hospital stay, neobladder performance, and blood loss/transfusion rate. EVIDENCE ACQUISITION: Medline, Embase, and the Cochrane Central Register of Controlled Trials were searched. Comparative studies published after the year of 2000 including patients who underwent RC for bladder cancer were eligible for inclusion. Partial cystectomy was an exclusion criterion. Risk of bias (RoB) assessment was performed according to the ROBINS-1 tool. EVIDENCE SYNTHESIS: After screening of 1190 abstracts, 39 studies recruiting 549 542 patients were included. All studies were retrospective observation cohort studies (level of evidence 3). Twenty-two studies reported on HV only, six studies on SV only, and 12 on both. Higher HV, specifically an HV of >10, was associated with improved primary and secondary outcomes in most studies. In addition, there is some evidence that an HV of >20 improves outcomes. For SV, limited and conflicting data are reported. Most studies had moderate to high RoB. The results were synthesized narratively. CONCLUSIONS: Acknowledging the lower level of evidence, HV is likely associated with in-hospital, 30- and 90-d mortality, as well as the secondary outcomes assessed. Based on this study, the European Association of Urology Muscle-invasive and Metastatic Bladder Cancer Guideline Panel recommends hospitals to perform at least 10, and preferably >20, RCs annually or refer the patient to a center that reaches this number. For SV, limited and confl

BACKGROUND: Although guidelines exist for advanced and variant bladder cancer management, evidence is limited/conflicting in some areas and the optimal approach remains controversial. OBJECTIVE: To bring together a large multidisciplinary group of experts to develop consensus statements on controversial topics in bladder cancer management. DESIGN: A steering committee compiled proposed statements regarding advanced and variant bladder cancer management which were assessed by 113 experts in a Delphi survey. Statements not reaching consensus were reviewed; those prioritised were revised by a panel of 45 experts prior to voting during a consensus conference. SETTING: Online Delphi survey and consensus conference. PARTICIPANTS: The European Association of Urology (EAU), the European Society for Medical Oncology (ESMO), experts in bladder cancer management. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Statements were ranked by experts according to their level of agreement: 1-3 (disagree), 4-6 (equivocal), and 7-9 (agree). A priori (level 1) consensus was defined as ≥70% agreement and ≤15% disagreement, or vice versa. In the Delphi survey, a second analysis was restricted to stakeholder group(s) considered to have adequate expertise relating to each statement (to achieve level 2 consensus). RESULTS AND LIMITATIONS: Overall, 116 statements were included in the Delphi survey. Of these statements, 33 (28%) achieved level 1 consensus and 49 (42%) achieved level 1 or 2 consensus. At the consensus conference, 22 of 27 (81%) statements achieved consensus. These consensus statements provide further guidance across a broad range of topics, including the management of variant histologies, the role/limitations of prognostic biomarkers in clinical decision making, bladder preservation strategies, modern radiotherapy techniques, the management of oligometastatic disease, and the evolving role of checkpoint inhibitor therapy in metastatic disease. CONCLUSIONS: These consensus stateme
