Importance Currently, there are no standardized outcome domains or measures in clinical trials for facial aging. Heterogeneity in outcome domains and measurement instruments across clinical trials creates difficulty in directly comparing interventions, determining superior therapies, and developing high-quality meta-analyses. Objective To develop a core outcome set (COS) of essential domains to be reported in clinical trials evaluating the efficacy of interventions for facial aging. Evidence Review PubMed/Medline, Embase, Cochrane Central Register of Controlled Trials, and CINAHL were searched from September 2005 to September 2015. An updated search of the same databases was performed from September 2015 to February 2026. Studies were included if (1) they were randomized clinical trial or controlled clinical trial in design, (2) they assessed the efficacy or safety of an intervention for facial aging, (3) they were published in English, and (4) they involved human participants. Complementary sources, including patient interviews, were used to capture further relevant outcomes. Two rounds of Delphi surveys, followed by consensus meetings, were used to identify outcome domains considered most important by both patient and physician stakeholders. Findings The final COS consists of 6 outcome domains: (1) overall convenience of treatment; (2) time to return to normal work and social activity; (3) overall assessment of focused area of treatment (at the point in time when treatment is expected to provide peak benefit); (4) duration of treatment effect; (5) severity of persistent local or systemic adverse events, including pigmentary change, skin texture change, delayed healing, scarring, and serious adverse events; and (6) patient satisfaction with treatment. Conclusions and Relevance The 6 outcome domains identified through a Delphi consensus are recommended for reporting in future facial aging trials to ensure that outcomes that matter most to patients and clinicians are measured and that results are comparable across interventions.

Abstract Therapeutic options for Waldenström macroglobulinemia (WM) have expanded but improvements in overall-survival (OS) are difficult to interpret due to competing non–WM mortality. We conducted a large single-center retrospective study of 1,020 patients with WM to evaluate survival trends. Patients were stratified by era of active WM diagnosis using a two-era model (1996–2005 and post-2005) and a four-era model (pre-2001, 2001–2007, 2008–2013, and post-2013). OS did not differ significantly across eras in the overall cohort (p = 0.64 and p = 0.86 for the two- and four-era models). However, among patients aged < 65 years at the time of active WM diagnosis in the 2-era model, OS improved in the post-2006 era (median 18.8 vs 14.1 years, p = 0.018). Cause-specific-survival (CSS) improved across all eras, increasing from 15.6 years in 1996–2005 to 18.9 years post-2006 (p < 0.0001), and from 13.7 years pre-2001 to not reached in later periods in the four-era model (p < 0.0001). Competing-risk-analysis (CRA) demonstrated a reduction in WM-related mortality over time (p < 0.001). However, excess mortality persisted, with a standardized mortality ratio (SMR) of 2.79 (p < 0.001) among patients < 65 years compared with a matched U.S. population. Our findings highlight improvements in WM-specific survival, while gains in OS are observed in younger patients.

Abstract Genome sequencing of the heterogeneous primary mitochondrial disorders (PMD) frequently reveals variants of uncertain significance that require functional tests for diagnosis, and does not identify variants in all patients. We analyzed mitochondrial enzyme assays, blue native polyacrylamide gel electrophoresis (BN-PAGE) with in-gel activity staining, complex I assembly blot, and select protein abundances in fibroblasts of a case series of 204 PMD patients divided into functional classes, in comparison to 51 controls and 53 differential diagnostic conditions. Overall, sensitivity and specificity for respiratory chain enzyme assays were 46% and 93% respectively, for BN-PAGE 40% and 98%, for complex I assembly assay 49% and 99%. The overall sensitivity of all tests was 76%, specificity 93%, with positive predictive value 96% and negative predictive value 67%. Categories with high sensitivity were isolated complex deficiencies, nuclear DNA-encoded mitochondrial protein synthesis defects, co-factor defects, and mitochondrial amino-acyl-tRNA synthetase conditions when aided by protein abundance. Mitochondrial DNA mutations and maintenance disorders showed poor sensitivities. Secondary dysfunctions were rare. A complete battery of functional tests showed strong diagnostic clinical utility in fibroblasts. One sentence summary A combination of four mitochondrial functional tests to identify or confirm suspected primary mitochondrial disease in fibroblasts had good sensitivity and excellent specificity, well beyond what was perceived using enzyme assays only.

PURPOSE In large B-cell lymphoma (LBCL), use of high-dose methotrexate (HD-MTX) to prevent CNS relapse (so-called CNS prophylaxis) remains controversial. International guidelines continue to recommend HD-MTX in patients deemed ultra high risk (UHR) because of a lack of robust data specific to these subgroups. This study was designed to examine the impact of HD-MTX specifically in UHR patients. METHODS Data from two previous retrospective analyses were combined to produce a cohort of UHR patients (≥1 of the following criteria: CNS international prognostic index score 5-6; testicular, renal/adrenal, or breast involvement; ≥3 extranodal sites), treated with or without HD-MTX. The primary outcome was CNS relapse rate (isolated or concurrent with systemic relapse) measured from diagnosis with additional landmark analysis of all responding patients with no progression event at 6 months. RESULTS Analyses were performed on 1,923 patients meeting UHR criteria. No significant difference in 3-year CNS relapse rate was observed between no HD-MTX (n = 1,051) versus HD-MTX patients (n = 872), including in multivariable analyses adjusting for baseline characteristics (3-year rate, 9.3% v 8.1%; adjusted hazard ratio [HR], 1.13 [95% CI, 0.82 to 1.57]). Analyses restricted to isolated CNS relapse also confirmed no difference (5.9% v 5.7%; adjusted HR, 1.03 [95% CI, 0.69 to 1.53]). In the landmark analysis (no HD-MTX n = 782, HD-MTX n = 773), no difference in 3-year CNS relapse was observed (6.7% v 6.6%, adjusted HR, 0.95 [95% CI, 0.62 to 1.44]). CONCLUSION To our knowledge, this is the largest international comparative data set of patients with LBCL with UHR features showing no significant reduction in CNS relapse with HD-MTX in all UHR or in any individual subgroup. Despite inherent limitations of retrospective analyses, the data strongly support previous studies in suggesting HD-MTX prophylaxis has no meaningful benefit for most patients.

ABSTRACT Primary plasma cell leukemia (pPCL) is a rare and aggressive plasma cell disorder with inferior outcomes compared with multiple myeloma (MM). However, studies describing outcomes after first progression and subsequent lines of therapy remain limited. We retrospectively analyzed 104 patients with pPCL who progressed after first‐line therapy treated at one comprehensive cancer center between 2006 and 2024. Clinical characteristics, treatments, time to next treatment (TTNT), and overall survival (OS) were assessed using Kaplan–Meier methods. All pPCL patients received novel agent–based induction. At the time of analysis, 63% had died; median OS was 39 months. High‐risk cytogenetics were present in 71%. The median TTNT after first‐line therapy was 10 months. Symptomatic progression occurred in 29% of patients and was associated with significantly inferior subsequent OS (13 vs. 34 months) compared with those experiencing asymptomatic biochemical progression. The TTNT progressively shortened with subsequent lines of therapy (3rd line: 6 months; 4th line: 4 months; 5th line: 3 months). Notable exceptions included pPCL patients with t (11;14) treated with anti‐BCL‐2‐based regimens, who achieved a median TTNT of 13 months. Additionally, 24 patients received anti‐BCMA CAR T‐cell therapy. With a median follow‐up of 21 months, their median TTNT was 32 months. pPCL is characterized by frequent disease progression and diminishing response duration with successive therapeutic lines. Symptomatic progression portends particularly poor outcomes. Anti‐BCL‐2‐based therapy in t (11;14) disease and anti‐BCMA CAR T‐cell therapy appear to provide more durable disease control and represent important advances for the management of progressed pPCL.

LBA7000 Background: ~40% of DLBCL pts are not cured with first-line (1L) R-CHOP, underscoring a significant unmet need for more effective 1L regimens. Tafa (anti-CD19 mAb) + Len-R-CHOP in the phase 1b First-MIND study demonstrated safety and efficacy in pts with newly diagnosed disease. frontMIND, a phase 3, double-blind, placebo-controlled study, compared Tafa-Len-R-CHOP vs R-CHOP in pts with high-risk aggressive BCLs. Methods: Pts aged 18–80 y with newly diagnosed, high-intermediate/high-risk DLBCL or HGBL (IPI 3–5, aaIPI 2–3 if ≤60 y) and ECOG PS 0–2 were randomized 1:1 to Tafa-Len-R-CHOP or R-CHOP. Primary endpoint was investigator-assessed PFS; secondary endpoints included: EFS, OS, CR, ORR, safety. Results: At primary analysis (data cutoff Oct 20, 2025), 899 pts were randomized to Tafa-Len-R-CHOP (n=448) or R-CHOP (n=451); baseline characteristics were similar between arms. With a median follow-up of 35.2 mo, Tafa-Len-R-CHOP achieved a statistically significant improvement in PFS vs R-CHOP (HR 0.75 [95% CI: 0.59, 0.96]; P =0.019) in the overall population; in pts with centrally confirmed lymphoma subtypes (n=773), PFS HR was 0.68 (95% CI: 0.52, 0.88) and 24-mo PFS was 72.7% vs 62.2%. PFS benefit was observed with Tafa-Len-R-CHOP in both molecular COO subtypes, ABC and GCB (data will be presented). Tafa-Len-R-CHOP significantly improved EFS vs R-CHOP; CR and ORR were similar between arms and HR for OS was 0.85 (final OS planned at 5y) (Table). Any-grade TEAEs were similar in treatment arms (98.6% vs 97.1%); more grade ≥3 TEAEs occurred with Tafa-Len-R-CHOP vs R-CHOP (86.7% vs 76.1%). Discontinuations due to TEAEs occurred in 25.7% vs 17.9% and deaths due to TEAEs in 5.9% vs 3.8% of pts for Tafa-Len-R-CHOP vs R-CHOP. Overall, there were fewer deaths with Tafa-Len-R-CHOP vs R-CHOP (18.5% vs 21.7%). Conclusions: The primary endpoint of frontMIND was met; Tafa-Len-R-CHOP resulted in a significant 25% reduction in risk of disease progression or death compared with R-CHOP, with an 8.2% difference in 24-month PFS rate in the overall population and 10.5% difference in pts with centrally confirmed lymphoma subtypes. TEAEs were manageable and consistent with the expected safety profile. Tafa-Len-R-CHOP represents a potential new 1L standard of care for pts with both COO subtypes of high-risk DLBCL or HGBL.

Abstract Background Machine perfusion represents the most significant breakthrough in liver transplantation (LT) since the discovery of cyclosporin. Yet, the optimal perfusion strategy remains unsettled. Randomized trials demonstrate that hypothermic oxygenated perfusion (HOPE) improves graft survival and function and reduces ischemic cholangiopathy, whereas normothermic machine perfusion (NMP) decreases post-transplant injury. Real-world comparisons are lacking and challenging due to heterogeneity in donor-recipient risk profiles and regional differences. Aims To compare real-world outcomes of HOPE and NMP in LT. Methods We analyzed consecutive NMP-preserved LTs from seven North American centers between 2021 and 2024. We compared NMP to the European HOPE-REAL cohort, comprising HOPE-treated LTs from 22 centers between 2012 and 2021. Analyses were stratifyied by graft type and risk category and adjusted for donor age, donor risk index, and balance of risk score using entropy balancing. Results A total of 470 NMP and 1202 HOPE-treated grafts were analyzed, revealing major differences in risk profiles (Figure 1). In NMP, death-censored graft survivals at 1, 2, and 3 years were &gt;95% in donation after brain death (DBD) and &gt;94% in donation after circulatory death (DCD) grafts. Comparable outcomes were observed in the HOPE cohort with &gt;93%, in DBD, and &gt;87% in DCD after up to 3 years, despite significantly higher donor age and longer functional warm ischemia in the HOPE DCD cohort (Figure 2). After risk adjustment, death-censored graft survival remained similar between both modalities (Table 1). Non-anastomotic biliary stricture rates after DCD-LT were comparable (8.5% vs. 12.4%), independent of whether continuous or end-ischemic NMP was performed. Conclusion This first transatlantic real-world report demonstrates excellent outcomes with both NMP and HOPE despite higher graft risk in Europe. Machine perfusion is the new standard of care in LT, while further understanding is needed regarding the distinct benefits of each modality across risk profiles.Figure 1.Graft risk in NMP and HOPE stratified by graft type.

e20511 Background: Trop-2 ADCs have emerged as a novel therapeutic approach in NSCLC that is refractory to chemotherapy and immune checkpoint inhibitors. Comparative interpretation of the efficacy of multiple Trop-2 ADCs, including Sacituzumab tirumotecan (Sac-TMT), Datopotamab deruxtecan (Dato-DXd), and Sacituzumab govitecan (SG), is limited. We therefore conducted a systematic review, IPD survival analysis, and meta-analysis to evaluate the efficacy and PROs of Trop-2 ADCs compared with chemotherapy in NSCLC. Methods: A systematic search was conducted from inception to October 31, 2025, across PubMed, Scopus, Cochrane, and CT.gov. Clinical trials evaluating Overall Survival (OS) and Progression-free survival (PFS) in patients treated with Trop-2 ADC alone or compared with Chemotherapy were included. IPD were extracted from the Kaplan-Meier curves of clinical trials for reconstruction using the KMfromIPD website by MD Anderson, which stratified the data by treatment group. Outcomes included OS, PFS, and time to deterioration (TTD). The cumulative data were analyzed using R 4.5.1 and RStudio. RevMan version 5.4.1 was used for the meta-analysis of subgroups. Heterogeneity was assessed using the I 2 statistic. Results: Of 513 articles, 7 phase 1/2 single-arm and 4 randomized control trials were included, comprising 2,619 patients.Trop-2 ADCs were associated with improved OS (Median 15.6 vs 12.5 months; HR 0.78, 95% CI 0.69-0.88; p < 0.0001) and PFS (Median 5.5 vs 4.1 months; HR 0.66, 95% CI 0.59-0.74; p < 0.0001). Sac-TMT demonstrated the greatest OS benefit (OS 23.3 months; HR 0.40). Further drug classes are depicted in Table 1. PROs assessment showed TROP-2 ADCs were associated with longer time to deterioration in global quality of life and dyspnea-free survival compared to chemotherapy (HR 0.8 and 0.69), (p = 0.04 and p < 0.0001, respectively). Exploratory subgroup analysis showed improved OS among patients with actionable gene alteration (AGA) treated with Trop-2 ADCs (HR 0.58, p < 0.00001). However, no significant difference was observed in either treatment arm among patients without AGA (HR 0.89, p = 0.15). Conclusions: Trop-2 ADCs were associated with improved survival and PROs compared with chemotherapy in NSCLC, with variability across agents. Sac-TMT has shown higher OS and PFS. Dato Dxd had a favorable PFS; however, the OS was not superior to chemo. Furthermore, SG showed no favorable clinical outcomes compared with the chemo group. These findings support the continued development of Trop-2-directed therapies and highlight the need for prospective comparative trials and biomarker-driven patient selection.
