Background: Breast cancer polygenic risk scores (PRS) and traditional risk models (e.g., the Gail model [Gail]) are known to contribute largely independent information, but it is unclear how the overlap varies by ancestry, age, disease type (invasive breast cancer, DCIS), and risk threshold. Methods: In a retrospective case–control study, we evaluated risk prediction performance in 180,398 women (161,849 of European ancestry; 18,549 of Asian ancestry). Odds ratios (ORs) from logistic regression models and the area under the receiver operating characteristic curve (AUC) were estimated. Results: PRS for invasive disease showed a stronger association in younger (<50 years) women (OR = 2.51, AUC = 0.622) than in women ≥ 50 years (OR = 2.06, AUC = 0.653) of European ancestry. PRS performance in Asians was lower (OR range = 1.62–1.64, AUC = 0.551–0.600). Gail performance was modest across groups and poor in younger Asian women (OR = 0.94–0.99, AUC = 0.523–0.533). Age interactions were observed for both PRS (p < 0.001) and Gail (p < 0.001) in Europeans, whereas in Asians, age interaction was observed only for Gail (invasive: p < 0.001; DCIS: p = 0.002). PRS identified more high-risk individuals than Gail in Asian populations, especially ≥50 years, while Gail identified more in Europeans. Overlap between PRS, Gail, and family history was limited at higher thresholds. Calibration analysis, comparing empirical and model-based ROC curves, showed divergence for both PRS and Gail (p < 0.001), which indicates miscalibration. In Europeans, family history and prior biopsies drove Gail discrimination. In younger Asians, age at first live birth was influential. Conclusions: PRS adds value to risk stratification beyond traditional tools, especially in younger women and Asian ancestry populations.

Abstract Understanding tumor cell dynamics can improve prognosis and treatment but remains limited for lung adenocarcinoma in people who have never smoked (NS-LUAD). With RNA sequencing data from 684 NS-LUAD cases and validation in an independent dataset, we identified three subtypes with distinct phenotypic traits and cell compositions. Additional genomic and histologic data further characterized the subtypes. “Steady,” marked by low proliferation, high alveolar cell fraction, moderate-to-well differentiation, and fewer driver gene alterations, is linked to prolonged survival and low immune evasion. “Proliferative” shows high proliferation markers, TP53 mutations, and gene fusions. “Chaotic,” with high epithelial-to-mesenchymal transition markers, has the worst prognosis, even within stage I tumors. Lacking known molecular or histologic characteristics, this aggressive subtype is solely identified by transcriptomic data. A 60-gene signature recapitulates the classification and predicts survival even within subgroups based on tumor stage or known genomic features, emphasizing its potential for improving early-stage NS-LUAD prognostication in clinical settings. Significance: The transcriptome of 684 NS-LUAD identifies three subtypes with different cellular dynamics and genomic and morphologic features. A 60-gene signature accurately stratifies subjects for mortality risk, even in stage I, offering a potential clinically applicable tool for treatment decision-making in patients with NS-LUAD.

Abstract Background and Aims Although the choice of dialysis technique is based on several factors, patient survival is undoubtedly one of the most relevant. In a context where randomization to either peritoneal dialysis (PD) or hemodialysis (HD) proved to be extremely challenging, previous meta-analyses were greatly limited due to the inclusion of historical studies. Method We performed a systematic review by searching multiple databases up to April 22nd, 2022. We included studies meeting the following criteria: adult patients (&gt;18 years) with end-stage kidney disease on dialysis; comparison of PD versus HD; reporting mortality data via intention-to-treat analysis; initiation of dialysis after 2000; patient classification by dialysis modality at 90 days post-initiation; and ≥50 patients per group (Figs 1 and 2). The primary outcome was the association between dialysis modality (PD vs HD) and mortality assessed via hazard ratios (HR) [Fig. 3]. Subgroup analyses were conducted to explore potential sources of heterogeneity, including sex, age, diabetes, dialysis vintage, geographical location, HD access, and study cohort inclusion period [Figs 4 and 5]. Results Database search yielded 5317 citations, from which, 27 observational studies met the eligibility criteria, including 1 033 362 incident dialysis patients [Figs 1 and 2]. The pooled mortality HR for PD versus HD was 1.01 (95% CI 0.93–1.10 [Fig. 3]). Heterogeneity was substantial (I2 = 94%) and was largely explained by different baseline features of the included populations. A statistically significant subgroup effect was demonstrated for age (&gt;65 vs.&lt;65 years; P = 0.01), geographical location of the studies (Oceania vs. Europe vs. Asia vs. North America; P &lt; 0.01), and HD vascular access (central venous catheter vs. arteriovenous fistula; P &lt; 0.01, only one study included) [Figs 4 and 5]. Conclusion This meta-analysis suggests that overall PD and incentre HD likely carry equivalent survival benefits. However, differences were detected among subgroups based on age, geographic location, HD access type, but not on sex, diabetes status, dialysis vintage and study cohort inclusion period.

Objective To investigate the diagnostic performance of perilesional biopsies (PLBx) compared to other biopsy strategies, assessing the impact of the Prostate Imaging‐Reporting and Data System (PI‐RADS) score and biopsy history in patients with a visible lesion at multiparametric magnetic resonance imaging of the prostate (mpMRI), as the European Association of Urology guidelines recommend combining MRI‐targeted biopsies (TBx) with PLBx as an alternative to systematic biopsies (SBx) even though evidence is limited. Patients and Methods We relied on a cohort of 2852 patients with PI‐RADS ≥3 lesions undergoing TBx + SBx at three tertiary referral centres. The primary outcome was detection of clinically significant PCa (csPCa) (International Society of Urological Pathology Grade Group [ISUP GG] ≥2) of TBx + PLBx vs TBx + SBx. Results were stratified by PI‐RADS score and biopsy history. The PLBx cores were defined as samples taken from prostate sectors adjacent to the mpMRI lesion. We finally assessed insignificant PCa (insPCa, i.e., ISUP GG 1) detection across biopsy strategies. Differences were assessed using the chi‐square test. Results Detection of csPCa was 48%. Overall, TBx + SBx had a higher csPCa detection rate than TBx + PLBx (50% vs 45%, P = 0.03), particularly in PI‐RADS 3 lesions (26% vs 21%, P = 0.02) and active surveillance (AS) patients (46% vs 40%, P = 0.04). No significant differences were found in PI‐RADS 4 (53% vs 50%, P > 0.1) or PI‐RADS 5 (76% vs 75%, P > 0.1). In the biopsy naïve and previous negative biopsy groups, csPCa detection was similar between strategies ( P > 0.1). Conclusions Overall, TBx + SBx offers the highest detection of csPCa. Even though TBx + PLBx may be considered in PI‐RADS 4–5 lesions to reduce insPCa detection, TBx + SBx remains the preferred strategy for PI‐RADS 3 and AS patients.

Abstract Background The results of a previous phase IIa trial suggested efficacy of the anti-C5a compound vilobelimab in a small number of patients with severe hidradenitis suppurativa (HS) refractory to adalimumab treatment. Objectives To study the efficacy of vilobelimab in a larger-scale randomized phase IIb trial (SHINE) of patients with moderate-to-severe HS. Methods In total, 177 patients with moderate-to-severe HS were treated either with placebo or one of four doses of vilobelimab, a monoclonal antibody that targets the complement split product C5a. Hidradenitis Suppurativa Clinical Response (HiSCR) at 16 weeks was the primary endpoint. Those who achieved HiSCR switched to open-label low-dose vilobelimab; those who did not were switched to medium-dose vilobelimab. The trial was registered with the EU Clinical Trials Register (EudraCT number 2017-004501-40) and ClinicalTrials.gov (NCT03487276). Results The study did not meet the primary endpoint, perhaps due, in part, to an unexpectedly high HiSCR placebo response rate of 47.1%. HS flares decreased and post hoc analysis showed that high-dose vilobelimab significantly decreased the median draining tunnel counts and IHS4 score by 63%. Following the switch to medium-dose vilobelimab at week 16, 45.5% of those who did not respond to treatment achieved HiSCR at week 40. Conclusions Compared with placebo, vilobelimab treatment did not result in significant HiSCR improvements in patients with moderate-to-severe HS. Post hoc analysis revealed significant effects for the highest tested dose on draining tunnel reduction and IHS4 score, which captures reductions in draining tunnels. These findings warrant further investigation.

Multiple myeloma (MM) is consistently preceded by monoclonal gammopathy of undetermined significance (MGUS) and smoldering multiple myeloma (SMM). While these precursor conditions are asymptomatic, they are not entirely benign and carry a lifelong risk of progression to MM. Unlike other cancers defined by pathology, malignant transformation from MGUS or SMM to MM has so far relied on demonstration of clinical end-organ damage as morphology and cytogenetics cannot reliably distinguish them. In this study, using genomic data from 374 patients with MGUS or SMM (277 training, 97 validation), to our knowledge, we demonstrate for the first time the ability to identify malignant transformation in MGUS and SMM. We introduce the concept of genomic MM and genomic MGUS to differentiate the subsets of MGUS and SMM that are biologically malignant with genomic features indistinguishable from MM from the subset that is premalignant and unlikely to progress to malignancy. Importantly, we find that most SMM has biological features of malignant transformation indistinguishable from MM. As expected, this subset that we consider having genomic MM is associated with a high risk of progression to MM although some patients remained progression-free beyond 5 years. Conversely, 60% of MGUS and 10% of SMM have no evidence of malignant transformation (genomic MGUS), with no progression during follow-up. Integration of genomic features with the 2/20/20 International Myeloma Working Group model significantly improved the prediction of progression among genomic MM. These findings support the use of genomic criteria to refine the classification and the risk stratification in myeloma precursor conditions.

Abstract Perioperative low cardiac output syndrome (LCOS) remains a significant complication in adult cardiac surgery, contributing to substantial morbidity, prolonged intensive care, and increased mortality. Its incidence is expected to rise further due to the evolving complexity of referred surgical patients, often characterised by advanced age, multiple comorbidities, challenging anatomy, and impaired haemodynamics. Despite advances in pharmacological and perioperative care, outcomes for high-risk patients have not shown significant improvement, prompting interest in temporary mechanical circulatory support (tMCS) as a proactive strategy. This Expert Consensus Document from the European Association for Cardio-Thoracic Surgery (EACTS) presents the first dedicated guidance on the pre-emptive use of tMCS in high-risk adult cardiac surgical patients. Developed by a multidisciplinary task force, it emphasises structured risk stratification, early initiation, and individualised device management informed by interdisciplinary Heart Team discussions. The document proposes clinical pathways for patient selection, defines criteria for tMCS initiation, and provides practical algorithms for various scenarios, including advanced heart failure, cardiogenic shock, and post-cardiotomy LCOS. It reviews the current evidence on available tMCS devices, such as intra-aortic balloon pumps, microaxial flow pumps, veno-arterial extracorporeal life support and hybrid strategies, and addresses perioperative care, intensive care unit protocols, ethical considerations, as well as informed consent and support withdrawal. Despite promising results, substantial knowledge gaps remain, including long-term outcome data, device selection criteria, and cost-effectiveness analyses. This consensus aims to support clinical decision-making, standardise practice, and stimulate research to improve outcomes in a growing population of high-risk surgical patients.

ABSTRACT Introduction Sinonasal sarcomas are exceedingly rare entities, constituting less than 7% of head and neck sarcomas. Their complex histology needs specialized treatment, which is often based on multimodal approaches including surgery, radiation therapy, and/or chemotherapy. This manuscript aims to gather expert opinions to establish common management principles for sinonasal sarcomas. Methods This international consensus followed a modified Delphi method in seven steps, including statements definition by the core group, expert panel recruitment, and a two‐round survey. Sixty‐two statements on sinonasal sarcoma management were developed. Experts from multiple continents participated, and results were anonymized and analyzed between March and May 2025. Results A total of 44 invited experts were recruited, 43.2% otorhinolaryngologists/head and neck surgeons, 31.8% medical oncologists, and 25% radiation oncologists. Participants varied in age and experience, representing Europe (70.5%), North America (18.2%), South America (6.8%), and Asia (4.5%). Among all histologies, biphenotypic sarcoma, chondrosarcoma, leiomyosarcoma, and myofibrosarcoma are principally treated with an upfront surgical management, differently from Ewing sarcoma and rhabdomyosarcoma in which chemotherapy, eventually associated with radiotherapy, is often chosen. In the remaining histologies (angiosarcoma, liposarcoma, malignant peripheral nerve sheath tumor [MPNST], osteosarcoma, and synovial sarcoma), a precise multimodal treatment is less standardized and needs to be discussed on a case‐by‐case basis. Conclusion Sinonasal sarcomas require a histology‐driven approach to determine upfront treatment, whether surgical, medical, or multimodal. Despite this structured strategy, prognosis remains highly variable across subtypes. Multidisciplinary evaluation and individualized management in referral centers are crucial to address the biological diversity and anatomical complexity of these rare malignancies.
