S100 proteins as potential predictive biomarkers of abatacept response in polyarticular juvenile idiopathic arthritis.

BACKGROUND: Juvenile idiopathic arthritis (JIA) comprises a heterogeneous group of conditions that can cause marked disability and diminished quality of life. Data on predictors of clinical response are insufficient to guide selection of the appropriate biologic agent for individual patients. This study aimed to investigate the propensity of S100A8/9 and S100A12 as predictive biomarkers of abatacept response in polyarticular-course juvenile idiopathic arthritis (pJIA). METHODS: Data from a phase 3 trial (NCT01844518) of subcutaneous abatacept in patients with active pJIA (n = 219) were used in this exploratory analysis. Association between biomarker levels at baseline and improvements in JIA-American College of Rheumatology (ACR) criteria responses or baseline disease activity (measured by Juvenile Arthritis Disease Activity Score in 27 joints using C-reactive protein [JADAS27-CRP]) were assessed. Biomarker level changes from baseline to month 4 were assessed for disease outcome prediction up to 21 months. RESULTS: At baseline, 158 patients had available biomarker samples. Lower baseline S100A8/9 levels (≤ 3295 ng/mL) were associated with greater odds of achieving JIA-ACR90 (odds ratio [OR]: 2.54 [95% confidence interval (CI): 1.25-5.18]), JIA-ACR100 (OR: 3.72 [95% CI: 1.48-9.37]), JIA-ACR inactive disease (ID; OR: 4.25 [95% CI: 2.03-8.92]), JADAS27-CRP ID (OR: 2.34 [95% CI: 1.02-5.39]) at month 4, and JIA-ACR ID (OR: 3.01 [95% CI: 1.57-5.78]) at month 16. Lower baseline S100A12 levels (≤ 176 ng/mL) were associated with greater odds of achieving JIA-ACR90 (OR: 2.52 [95% CI: 1.23-5.13]), JIA-ACR100 (OR: 3.68 [95% CI: 1.46-9.28]), JIA-ACR ID (OR: 3.66 [95% CI: 1.76-7.61]), JIA-ACR90 (OR: 2.03 [95% CI: 1.07-3.87]), JIA-ACR100 (OR: 2.14 [95% CI: 1.10-4.17]), and JIA-ACR ID (OR: 4.22 [95% CI: 2.15-8.29]) at month 16. From baseline to month 4, decreases in S100A8/9 and S100A12 generally exceeded 50% among JIA-ACR90/100/ID responders. CONCLUSION: Lower baseline levels of S100A8/9 and S100A12 proteins predicted better response to abatacept treatment than higher levels and may serve as early predictive biomarkers in pJIA. Decreases in these biomarker levels may also predict longer-term response to abatacept in pJIA.

Safety and efficacy of tofacitinib for the treatment of patients with juvenile idiopathic arthritis: preliminary results of an open-label, long-term extension study.

OBJECTIVES: We report the safety, tolerability and efficacy of tofacitinib in patients with juvenile idiopathic arthritis (JIA) in an ongoing long-term extension (LTE) study. METHODS: Patients (2-<18 years) with JIA who completed phase 1/3 index studies or discontinued for reasons excluding treatment-related serious adverse events (AEs) entered the LTE study and received tofacitinib 5 mg two times per day or equivalent weight-based doses. Safety outcomes included AEs, serious AEs and AEs of special interest. Efficacy outcomes included improvement since tofacitinib initiation per the JIA-American College of Rheumatology (ACR)70/90 criteria, JIA flare rate and disease activity measured by Juvenile Arthritis Disease Activity Score (JADAS)27, with inactive disease corresponding to JADAS ≤1.0. RESULTS: Of 225 patients with JIA (median (range) duration of treatment, 41.6 (1-103) months), 201 (89.3%) had AEs; 34 (15.1%) had serious AEs. 10 patients developed serious infections; three had herpes zoster. Two patients newly developed uveitis. Among patients with polyarticular course JIA, JIA-ACR70/90 response rates were 60.0% (78 of 130) and 33.6% (47 of 140), respectively, at month 1, and generally improved over time. JIA flare events generally occurred in <5% of patients through to month 48. Observed mean (SE) JADAS27 was 22.0 (0.6) at baseline, 6.2 (0.7) at month 1 and 2.8 (0.5) at month 48, with inactive disease in 28.8% (36 of 125) of patients at month 1 and 46.8% (29 of 82) at month 48. CONCLUSIONS: In this interim analysis of LTE study data in patients with JIA, safety findings were consistent with the known profile of tofacitinib, and efficacy was maintained up to month 48. TRIAL REGISTRATION NUMBER: NCT01500551.

Patient experience and satisfaction after same-day discharge radical prostatectomy using a personalized, digital perioperative programme.

PURPOSE: To assess the patient experience and satisfaction after the implementation in routine of a personalized, digital programme before and after same-day discharge (SDD) robot-assisted radical prostatectomy (RARP). METHODS: The study is a pre/post-interventional, multi-surgeon, unicentre, prospective study. All consecutive patients undergoing SDD RARP were included during a 6-month period. After a pre-interventional assessment of the satisfaction rate (n = 26), all patients (n = 46) were introduced to the Betty. Care platform and followed the BETTY COACHING programme which included a specific radical prostatectomy module. The primary endpoint was patient satisfaction 6 weeks after SDD RARP. Secondary endpoints were hospital stay, readmission and complications rates, unplanned visits, and remote monitoring data. RESULTS: Median age and PSA were 66 years and 7.0 ng/ml. Lymph node-dissection and nerve-sparing procedures were performed in 41.3 and 87.0% of patients, respectively. Median operative time and blood loss were 80 min and 150 ml, respectively. The 90-day rates of unplanned visits, readmission and complications were improved after the digital tool implementation (2.2, 2.2, and 8.7%, respectively). Mean satisfaction score was 9.6 out of 10 (8.0 before implementation). Median duration of pain was 2 days after discharge, with median pain intensity of 2/10. Median duration of daily active use of remote monitoring was 34 days. The urinary continence rate was 91.3% 6 weeks after surgery in the postinterventional cohort. CONCLUSIONS: The implementation of a personalized, surgery-specific, digital programme combining prehabilitation, patient education, rehabilitation, patient-reported outcome measurement and remote monitoring, improves patient experience and satisfaction and could help promoting early discharge even after a major surgery.

Consistencies in Follow-up After Radical Cystectomy for Bladder Cancer: A Framework Based on Expert Practices Collaboratively Developed by the European Association of Urology Bladder Cancer Guideline Panels.

BACKGROUND AND OBJECTIVE: There is no standardized regimen for follow-up after radical cystectomy (RC) for bladder cancer (BC). To address this gap, we conducted a multicenter study involving urologist members from the European Association of Urology (EAU) bladder cancer guideline panels. Our objective was to identify consistent post-RC follow-up strategies and develop a practice-based framework based on expert opinion. METHODS: We surveyed 27 urologist members of the EAU guideline panels for non-muscle-invasive bladder cancer and muscle-invasive and metastatic bladder cancer using a pre-tested questionnaire with dichotomous responses. The survey inquired about follow-up strategies after RC and the use of risk-adapted strategies. Consistency was defined as >75% affirmative responses for follow-up practices commencing 3 mo after RC. Descriptive statistics were used for analysis. KEY FINDINGS AND LIMITATIONS: We received responses from 96% of the panel members, who provided data from 21 European hospitals. Risk-adapted follow-up is used in 53% of hospitals, with uniform criteria for high-risk (at least ≥pT3 or pN+) and low-risk ([y]pT0/a/1N0) cases. In the absence of agreement for risk-based follow up, a non-risk-adapted framework for follow-up was developed. Higher conformity was observed within the initial 3 yr, followed by a decline in subsequent follow-up. Follow-up was most frequent during the first year, including patient assessments, physical examinations, and laboratory tests. Computed tomography of the chest and abdomen/pelvis was the most common imaging modality, initially at least biannually, and then annually from years 2 to 5. There was a lack of consistency for continuing follow-up beyond 10 yr after RC. CONCLUSIONS AND CLINICAL IMPLICATIONS: This practice-based post-RC follow-up framework developed by EAU bladder cancer experts may serve as a valuable guide for urologists in the absence of prospective randomized studies. PATIENT SUMMARY: We asked urologists from the EAU bladder cancer guideline panels about their patient follow-up after surgical removal of the bladder for bladder cancer. We found that although urologists have varying approaches, there are also common follow-up practices across the panel. We created a practical follow-up framework that could be useful for urologists in their day-to-day practice.

Robotic-assisted radical cystectomy with cutaneous ureterostomies: a contemporary multicenter analysis.

BACKGROUND: Robotic-assisted radical cystectomy (RARC) offers decreased blood loss during surgery, shorter hospital length of stay, and lower risk for thromboembolic events without hindering oncological outcomes. Cutaneous ureterostomies (UCS) are a seldom utilized diversion that can be a suitable alternative for a selected group of patients with competing co-morbidities and limited life expectancy. OBJECTIVE: To describe operative and perioperative characteristics as well as oncological outcomes for patients that underwent RARC + UCS. METHODS: Patients that underwent RARC + UCS during 2013-2023 in 3 centers (EU = 2, US = 1) were identified in a prospectively maintained database. Baseline characteristics, pathological, and oncological outcomes were analyzed. Descriptive statistics and survival analysis were performed using R language version 4.3.1. RESULTS: Sixty-nine patients were included. The median age was 77 years (IQR 70-80) and the median follow-up time was 11 months (IQR 4-20). Ten patients were ASA 4 (14.5%). Nine patients underwent palliative cystectomy (13%). The median operation time was 241 min (IQR 202-290), and the median hospital stay was 8 days (IQR 6-11). The 30-day complication rate was 55.1% (grade ≥ 3a was 14.4%), and the 30-day readmission rate was 17.4%. Eleven patients developed metastatic recurrence (15.9%), and 14 patients (20.2%) died during the follow-up period. Overall survival at 6, 12, and 24 months was 84%, 81%, and 73%, respectively. CONCLUSIONS: RARC + UCS may offer lower complication and readmission rates without the need to perform enteric anastomosis, it can be considered in a selected group of patients with competing co-morbidities, or limited life expectancy. Larger prospective studies are necessary to validate these results.

Oncologic surveillance intensity after endoscopic treatment of upper tract urothelial carcinoma.

BACKGROUND: The optimal oncologic surveillance in patients with upper tract urothelial carcinoma (UTUC) elected for conservative treatment is still a matter of debate. METHODS: Patients elected for endoscopic treatment of UTUC were followed up according to EAU guidelines recommendations after treatment. Bladder cancer recurrence-free survival (BCa-RFS), UTUC recurrence-free survival (UTUC-RFS), radical nephroureterectomy-free survival (RNU-FS), and cancer-specific survival (CSS) were estimated using the Kaplan-Meier method. The crude risks of BCa and UTUC recurrences over time were estimated with the Locally Weighted Scatterplot Smoothing method. RESULTS: Overall, 54 and 55 patients had low- and high-risk diseases, respectively. Median follow-up was 46.9 (IQR: 28.7-68.7) and 36.9 (IQR: 19.8-60.1) months in low and high-risk patients, respectively. In low-risk patients, BCa recurrence risk was more than 20% at 24 months follow-up. At 60 months, time point after which cystoscopy and imaging should be interrupted, the risk of BCa recurrence and UTUC recurrence were 14% and 7%, respectively. In high-risk patients, the risk of BCa and UTUC recurrence at 36 months was approximately 40% and 10%, respectively. Conversely, at 60 months, the risk of bladder recurrence and UTUC recurrence was 28% and 8%, respectively. CONCLUSIONS: For low-risk patients, cystoscopy should be performed semi-annually until 24 months, while upper tract assessment should be obtained up to 60 months, as per current EAU guidelines recommendations. For high-risk patients, upper tract assessment should be intensified to semi-annually up to 36 months, then obtained yearly. Conversely, cystoscopy should be ideally performed semi-annually until 60 months and yearly thereafter.

Complications of immuno-oncology care: what urologist should know.

OBJECTIVES: To provide a practical review of immune-related adverse events (irAEs) that may be encountered in uro-oncology patients. PATIENTS AND METHODS: We conducted a literature review of studies reporting irAEs including articles published through September 2023 for uro-oncology patients and the potential relevancy for the practicing urologist. RESULTS: Immunotherapy has revolutionised cancer treatment, extending its impact to urological malignancies including for patients with urothelial, kidney, and prostate cancers. Immuno-oncology (IO) compounds have achieved measurable and durable responses in these cancers. Urologists, choosing to administer or co-manage IO patient care, should be prepared to understand, evaluate, and treat irAEs. This review discusses the spectrum of irAEs that can be encountered. Ongoing trials are exploring the use of immunotherapy at earlier stages of uro-oncological diseases, thus underscoring the evolving landscape of urological cancer treatment. Paradoxically, some data suggests that the occurrence of irAEs is associated with improved oncological outcomes. CONCLUSIONS: Immune-related AEs, while manageable, may be life-threatening and require lifelong therapy. A thorough understanding of AEs and toxicity of a novel drug class is imperative.

Influence of lamina propria invasion extension on T1 high-grade non-muscle-invasive bladder cancer in patients undergoing BCG or radical cystectomy.

OBJECTIVE: To evaluate the prognostic value of T1 substaging in patients treated with bacillus Calmette-Guérin (BCG) or immediate radical cystectomy (iRC). MATERIALS AND METHODS: We performed an institutional review board-approved retrospective study analysing non-muscle-invasive bladder cancer (NMIBC) patients with pT1 disease treated with either BCG or iRC between 2000 and 2020. Lamina propria (LP) invasion characteristics were extracted from the pathology report. The Kaplan-Meier method was used to calculate overall survival (OS), cancer-specific survival (CSS) and metastasis-free survival (MFS). Multivariable Cox models were used to determine the association between progression-free survival (PFS) and characteristics in the BCG cohort. A logistic regression model explored the relationship between T1 substaging and upstaging to >pT2 at iRC. RESULTS: A total of 411 T1 high-grade patients were identified. LP invasion characteristics were as follows: not specified: 115 (28%); focal/superficial (F/S): 147 (35.8%); and extensive/multifocal (E/M): 149 (36.2%). Overall, 303 patients (73.7%) received BCG, and 108 patients (26.3%) underwent iRC. The median (interquartile range) follow-up was 53 (32-96) months. Patients with E/M LP invasion were significantly more likely to undergo iRC (34% vs. 19%; P = 0.003). Patients with E/M LP invasion showed poorer MFS and CSS compared to those with F/S LP invasion when treated with BCG but not when treated with iRC. Among BCG-treated patients, progression occurred in 41 patients and E/M LP invasion was independently associated with progression after BCG (hazard ratio 5.3, 95% confidence interval [CI] 2.2-13.1; P < 0.001). T1 substaging was not associated with upstaging at RC (odds ratio 3.15, 95% CI 0.82-12.12; P = 0.095). CONCLUSIONS: Extensive/multifocal LP invasion was associated with poor PFS, MFS and CSS in patients treated with BCG. T1 substaging provides valuable prognostic information and should be reported in pathology reports.

External validation of an algorithm to personalize nerve sparing approaches during robot-assisted radical prostatectomy in men with unilateral high-risk prostate cancer.

Limited evidence exists about preserving neurovascular bundles during radical prostatectomy (RP) for high-risk prostate cancer (HRPCa) patients. Hence, we validated an existing algorithm predicting contralateral extraprostatic extension (cEPE) risk in unilateral high-risk cases. This algorithm aims to assist in determining the suitability of unilateral nerve-sparing RP. Among 264 patients, 48 (18%) had cEPE. The risk of cECE varied: 8%, 17.2%, and 30.8% for the low, intermediate, and high-risk groups, respectively. Despite a higher risk of cECE among individuals classified as low-risk in the development group compared to the validation group, our algorithm's superiority over always/never nerve-sparing RP was reaffirmed by decision curve analysis. Therefore, we conclude that bilateral excision may not always be justified in men with unilateral HRPCa. Instead, decisions can be based on our suggested nomogram.

An updated model for predicting side-specific extraprostatic extension in the era of MRI-targeted biopsy.

PURPOSE: Accurate prediction of extraprostatic extension (EPE) is pivotal for surgical planning. Herein, we aimed to provide an updated model for predicting EPE among patients diagnosed with MRI-targeted biopsy. MATERIALS AND METHODS: We analyzed a multi-institutional dataset of men with clinically localized prostate cancer diagnosed by MRI-targeted biopsy and subsequently underwent prostatectomy. To develop a side-specific predictive model, we considered the prostatic lobes separately. A multivariable logistic regression analysis was fitted to predict side-specific EPE. The decision curve analysis was used to evaluate the net clinical benefit. Finally, a regression tree was employed to identify three risk categories to assist urologists in selecting candidates for nerve-sparing, incremental nerve sparing and non-nerve-sparing surgery. RESULTS: Overall, data from 3169 hemi-prostates were considered, after the exclusion of prostatic lobes with no biopsy-documented tumor. EPE was present on final pathology in 1,094 (34%) cases. Among these, MRI was able to predict EPE correctly in 568 (52%) cases. A model including PSA, maximum diameter of the index lesion, presence of EPE on MRI, highest ISUP grade in the ipsilateral hemi-prostate, and percentage of positive cores in the ipsilateral hemi-prostate achieved an AUC of 81% after internal validation. Overall, 566, 577, and 2,026 observations fell in the low-, intermediate- and high-risk groups for EPE, as identified by the regression tree. The EPE rate across the groups was: 5.1%, 14.9%, and 48% for the low-, intermediate- and high-risk group, respectively. CONCLUSION: In this study we present an update of the first side-specific MRI-based nomogram for the prediction of extraprostatic extension together with updated risk categories to help clinicians in deciding on the best approach to nerve-preservation.

The Financial Burden of Guideline-recommended Cancer Medications for Metastatic Urothelial Carcinoma.

Bladder cancer is a significant global health concern owing to its prevalence, negative impact on quality of life, and high treatment costs. Treatment for metastatic urothelial carcinoma (mUC) traditionally relies on platinum-based chemotherapy regimens. However, clinical trial results have led to the approval of immune checkpoint inhibitors (ICIs) as viable treatment options. We assessed the escalating costs and economic viability of mUC treatment guidelines in Europe. We used a pragmatic approach that involved: (1) collection of the costs of the recommended medications in the five most populous European countries; (2) conversion of the costs into international dollars to account for differences in purchasing power parity among countries; (3) evaluation of the cost trends over time; and (4) comparison of the medication costs to World Health Organization thresholds. Introduction of ICIs in European guidelines substantially increased the cost of medications for mUC. Intriguingly, important differences across European countries emerged: the annual cost of medications was twofold higher in Italy than in France and the UK. Despite limitations, our study sheds light on the escalating costs and economic challenges of mUC treatment, and highlights the need for assessments of sustainable and cost-effective management approaches. PATIENT SUMMARY: We looked at the costs of treatments for metastatic bladder cancer and found that costs have been rising over time, especially with the introduction of new immune therapies, with notable differences among European countries. While these new treatments improve patient outcomes, they also come with a high price tag, which could strain health care budgets. Our results suggest that cost-effectiveness studies will be essential in determining the best and most sustainable treatment strategies in the future.

Safety and effectiveness of abatacept in juvenile idiopathic arthritis: results from the PRINTO/PRCSG registry.

OBJECTIVE: To report the interim 5-year safety and effectiveness of abatacept in patients with juvenile idiopathic arthritis (JIA) in the PRINTO/PRCSG registry. METHODS: The Abatacept JIA Registry (NCT01357668) is an ongoing observational study of children with JIA receiving abatacept; enrolment started in January 2013. Clinical sites enrolled patients with JIA starting or currently receiving abatacept. Eligible patients were assessed for safety (primary end point) and effectiveness over 10 years. Effectiveness was measured by clinical 10-joint Juvenile Arthritis Disease Activity Score (cJADAS10) in patients with JIA over 5 years. As-observed analysis is presented according to the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) guidelines. RESULTS: As of 31 March 2020, 587 patients were enrolled; 569 are included in this analysis (including 134 new users) with 1214.6 patient-years of safety data available. Over 5 years, the incidence rate (IR) per 100 patient-years of follow-up of serious adverse events was 5.52 (95% confidence interval [CI]: 4.27, 7.01) and of events of special interest was 3.62 (95% CI: 2.63, 4.86), with 18 serious infections (IR 1.48 [95% CI: 0.88, 2.34]). As early as month 3, 55.9% of patients achieved cJADAS10 low disease activity and inactive disease (20.3%, 72/354 and 35.6%, 126/354, respectively), sustained over 5 years. Disease activity measures improved over 5 years across JIA categories. CONCLUSION: Abatacept was well tolerated in patients with JIA, with no new safety signals identified and with well-controlled disease activity, including some patients achieving inactive disease or remission.

The immune-related adverse events paradox in locally advanced or metastatic urothelial cancer after atezolizumab immunotherapy: analysis of individual patient data from IMvigor210 and IMvigor211 trials.

OBJECTIVE: To investigate the association between immune-related adverse events (irAEs) and oncological outcomes in patients with advanced urothelial cancer receiving immune checkpoint inhibitors (ICIs), and whether the administration of systemic corticosteroids diminishes therapeutic impact. PATIENTS AND METHODS: The association between irAEs occurrence and clinical progression-free survival (PFS), overall survival (OS), and cancer-specific survival (CSS) was tested by means of multivariable Cox or competing-risks regression, when appropriate. Patients experiencing irAEs were further stratified based on systemic corticosteroids administration. A sensitivity analysis was conducted by repeating all the analyses with median time to irAE as landmark point. RESULTS: We relied on individual participant data from two prospective trials for advanced urothelial cancer: IMvigor210 and IMvigor211. A total of 896 patients who received atezolizumab for locally advanced or metastatic urothelial cancer were considered. Overall, irAEs were recorded in 195 patients and the median time to irAEs was 64 days. On multivariable analysis, irAEs were inversely associated with the risk of disease progression (hazard ratio [HR] 0.50, 95% confidence interval [CI] 0.40-0.61; P < 0.001), overall mortality (HR 0.51, 95% CI 0.41-0.64; P < 0.001), and cancer-specific mortality (subdistributional HR [sHR] 0.55, 95% CI 0.45-0.72; P < 0.001). Moreover, our results did not refute the supposition that the administration of systemic corticosteroids does not impact oncological outcomes (PFS: HR 0.92, 95% CI 0.62-1.34, P = 0.629; OS: HR 0.86, 95% CI 0.51-1.64, P = 0.613; CSS: sHR 0.90, 95% CI 0.60-1.36, P = 0.630). The sensitivity analysis confirmed our findings. CONCLUSIONS: The development of irAEs while receiving atezolizumab treatment was associated with improved oncological outcomes, namely overall and cancer-specific mortality, and PFS. These findings seem to not be substantially affected by administration of systemic corticosteroids.

Impact of age >70 years on oncological outcomes in patients with non-muscle-invasive bladder cancer treated with Bacillus Calmette-Guérin.

OBJECTIVE: To evaluate the impact of age on oncological outcomes in a large contemporary cohort of patients with non-muscle-invasive bladder cancer (NMIBC) treated with adequate Bacillus Calmette-Guérin (BCG). PATIENTS AND METHODS: We performed an Institutional Review Board-approved retrospective study analysing patients with NMIBC treated with adequate BCG at our institution from 2000 to 2020. Adequate BCG was defined as per United States Food and Drug Administration (FDA) guidelines as being receipt of at least five of six induction BCG instillations with a minimum of two additional doses (of planned maintenance or of re-induction) of BCG instillations within a span of 6 months. The study's primary outcome was to determine if age >70 years was associated with progression to MIBC cancer or distant metastasis. The cumulative incidence method and the competing-risk regression analyses were used to investigate the association of advanced age (>70 years) with progression, high-grade (HG) recurrence and cancer-specific mortality (CSM). RESULTS: Overall, data from 632 patients were analysed: 355 patients (56.2%) were aged ≤70 years and 277 (43.8%) were >70 years. Age >70 years did not adversely affect either cumulative incidence of progression or HG recurrence (P = 0.067 and P = 0.644, respectively). On competing-risk regression analyses, age >70 years did not emerge as an independent predictor of progression or HG recurrence (sub-standardised hazard ratio [SHR] 1.57, 95% confidence interval [CI] 0.87-2.81, P = 0.134; and SHR 1.05, 95% CI 0.77-1.44, P = 0.749). Not unexpectedly, patients in the older group did have higher overall mortality (P < 0.001) but not CSM (P = 0.057). CONCLUSION: Age >70 years was not associated with adverse oncological outcomes in a large contemporary cohort of patients receiving adequate intravesical BCG for NMIBC. BCG should not be withheld from older patients seeking for bladder sparing options.

Ten-year safety and clinical benefit from open-label etanercept treatment in children and young adults with juvenile idiopathic arthritis.

OBJECTIVES: CLIPPER2 was an 8-year, open-label extension of the phase 3b, 2-year CLIPPER study on the safety and efficacy of etanercept in patients with JIA, categorized as extended oligoarticular arthritis (eoJIA), enthesitis-related arthritis (ERA) or PsA. METHODS: Participants with eoJIA (2-17 years old), ERA or PsA (each 12-17 years old) who received ≥1 etanercept dose (0.8 mg/kg weekly; maximum 50 mg) in CLIPPER could enter CLIPPER2. Primary end point was occurrence of malignancy. Efficacy assessments included proportions achieving JIA ACR 30/50/70/90/100 criteria and ACR inactive disease criteria, and clinical remission (ACR criteria) or Juvenile Arthritis DAS (JADAS) ≤1. RESULTS: Overall, 109/127 (86%) CLIPPER participants entered CLIPPER2 [n = 55 eoJIA, n = 31 ERA, n = 23 PsA; 99 (78%) on active treatment]; 84 (66%) completed 120 months' follow-up [32 (25%) on active treatment]. One malignancy (Hodgkin's disease in 18-year-old patient with eoJIA treated with methotrexate for 8 years) was reported; there were no cases of active tuberculosis or deaths. Numbers and incidence rates (events per 100 patient-years) of TEAEs (excluding infections/ISRs) decreased from 193 (173.81) in Year 1 to 9 (27.15) in Year 10; TE infections and serious infections also decreased. Over 45% of participants (n = 127) achieved JIA ACR50 responses from Month 2 onwards; 42 (33%) and 34 (27%) participants achieved JADAS and ACR clinical remission, respectively. CONCLUSIONS: Etanercept treatment up to 10 years was well tolerated, consistent with the known safety profile, with durable response in the participants still on active treatment. The benefit-risk assessment of etanercept in these JIA categories remains favourable. TRIAL REGISTRATION: ClinicalTrials.gov IDs: CLIPPER (NCT00962741); CLIPPER2 (NCT01421069).

European Association of Urology Guidelines on Muscle-invasive and Metastatic Bladder Cancer: Summary of the 2023 Guidelines.

CONTEXT: We present an overview of the updated 2023 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 guidelines has been performed annually since 2017. Searches cover the Medline, EMBASE, and Cochrane Libraries databases for yearly guideline updates. A level of evidence and strength of recommendation are assigned. The evidence cutoff date for the 2023 MIBC guidelines was May 4, 2022. EVIDENCE SYNTHESIS: Patients should be counselled regarding risk factors for bladder cancer. Pathologists should describe tumour and lymph nodes in detail, including the presence of histological subtypes. The importance of the presence or absence of urothelial carcinoma (UC) in the prostatic urethra is emphasised. Magnetic resonance imaging (MRI) of the bladder is superior to computed tomography (CT) for disease staging, specifically in differentiating T1 from T2 disease, and may lead to a change in treatment approach in patients at high risk of an invasive tumour. Imaging of the upper urinary tract, lymph nodes, and distant metastasis is performed with CT or MRI; the additional value of flurodeoxyglucose positron emission tomography/CT still needs to be determined. Frail and comorbid patients should be evaluated by a multidisciplinary team. Postoperative histology remains the most important prognostic variable, while circulating tumour DNA appears to be an interesting predictive marker. Neoadjuvant systemic therapy remains cisplatin-based. In motivated and selected women and men, sexual organ-preserving cystectomy results in better functional outcomes without compromising oncological outcomes. Robotic and open cystectomy have comparable outcomes and should be combined with (extended) lymph node dissection. The diversion type is an individual choice after taking patient and tumour characteristics into account. Radical cystectomy remains a highly complex procedure with considerable morbidity and risk of mortality, although lower rates are observed for higher hospital volumes (>20 cases/yr). With proper patient selection, trimodal therapy (chemoradiation) has comparable outcomes to radical cystectomy. Adjuvant chemotherapy after surgery improves disease-specific survival and overall survival (OS) in patients with high-risk disease who did not receive neoadjuvant treatment, and is strongly recommended. There is a weak recommendation for adjuvant nivolumab, as OS data are not yet available. Health-related quality of life should be assessed using validated questionnaires at baseline and after treatment. Surveillance is needed to monitor for recurrent cancer and functional outcomes. Recurrences detected on follow-up seem to have better prognosis than symptomatic recurrences. CONCLUSIONS: This summary of the 2023 EAU guidelines provides updated information on the diagnosis and treatment of MMIBC for incorporation into clinical practice. PATIENT SUMMARY: The European Association of Urology guidelines panel on muscle-invasive and metastatic bladder cancer has released an updated version of the guideline containing information on diagnosis and treatment of this disease. Recommendations are based on studies published up to May 4, 2022. Surgical removal of the bladder and bladder preservation are discussed, as well as updates on the use of chemotherapy and immunotherapy in localised and metastatic disease.
