Abstract Background: Despite its widespread adoption, there is a lack of data as to whether breast MRI for local staging and surgical planning of newly diagnosed breast cancer patients improves oncologic outcomes. The Alliance A011104 phase III trial was designed to test the hypothesis that MRI detection of mammographically occult disease helps to tailor surgical intervention thereby reducing local recurrence and improving local regional control. Here we report on the primary outcome of 5-year local regional recurrence. Methods: Patients with newly diagnosed clinical stage I-II, ER/PR- and HER2- negative (triple- negative) or ER/PR-negative and HER2-positive breast cancer, deemed eligible for breast- conserving surgery (BCS) based on clinical exam, mammography +/- ultrasound were randomized to undergo staging breast MRI or no further local staging. Patients with multifocal tumors that could be encompassed in a single operative resection were eligible. Patients who were carriers of gBRCA 1/2, or who had bilateral breast cancer, or a prior history of breast cancer were excluded. Initial eligibility was limited to patients not scheduled to receive neoadjuvant chemotherapy; however, a subsequent amendment allowed for enrollment after completion of neoadjuvant chemotherapy. Categorical variables were compared between arms with a chi-square or Fisher’s exact test. LRR, distant recurrence and overall survival (OS) were estimated with Kaplan-Meier point estimates and 95% confidence intervals (CIs). Hazard ratios (HRs) and 95% CIs were obtained from Cox proportional hazards models. Results: Of 319 patients enrolled from 2/2014-12/2019,161 were randomized to undergo breast MRI and 158 to no breast MRI evaluation. The mean age at enrollment was 58.9 years (range 29-85). Most patients (72.1%) had T1 tumors, 93.4% were cN0 and 19.7% were HER2 positive. Systemic chemotherapy was utilized in 85% with 17.6% receiving treatment neoadjuvantly; receipt of systemic therapy was unknown for 15 patients (4.7%). Two hundred and ninety-eight patients (93.4%) underwent surgical intervention; 91.9% underwent BCS as initial surgical procedure with no significant differences noted between groups (92.7% in the no MRI group and 91.9% in the MRI group [p=0.62]). Of patients who underwent breast surgery, 293 underwent axillary evaluation with the majority (270 patients, 92%) undergoing sentinel lymph node biopsy as the only axillary intervention. Among patients who received neoadjuvant chemotherapy, the overall pathologic complete response rate was 39.3%, 29.0%in the MRI arm vs. 52.0% no MRI arm (p=0.10). Receipt of adjuvant radiation was comparable between arms, 85.4% and 85.0% receiving radiation in the no MRI and MRI arms, respectively. Among 298 patients evaluable for the primary endpoint, with median follow-up of 61.1 months (0.2, 68.1), there were no differences in rates of LRR; 5-year local regional control was 93.2% (89.0-97.6%) in the MRI group and 95.7% (92.3-99.1%) in the no MRI group (HR: 1.1, 95% CI: 0.3, 3.9). For the entire cohort, 5-year distant recurrence-free rate and OS were 94.3% (91.7, 97.1) and 92.2% (89.1, 95.4), respectively, with no differences between groups. Conclusions: With multimodality therapy, rates of 5-year LRR in patients with early stage triple- negative and HER2-positive breast cancer are very low. Breast MRI for local staging and surgical planning in this setting does not result in improved local regional control.

INTRODUCTION: The American College of Gastroenterology assembled a multidisciplinary task force to evaluate the current state and future direction of artificial intelligence (AI) in gastroenterology, hepatology, and endoscopy leading to the development of consensus-based recommendations for responsible AI integration in clinical practice. METHODS: A total of 32 subject-matter experts and 12 industry partners, representing diverse practice settings and expertise, conducted subgroup literature reviews across 5 key areas (endoscopy, practice management clinical applications, training and education, inflammatory bowel disease and liver disease, ethics and equity). Draft statements were developed and rated on a 5-point Likert scale using a modified Delphi process. A consensus was set at ≥70% combined agreement. Nonconsensus items were revised and revoted electronically. RESULTS: A total of 43 statements, 40 (93%) reached consensus in round 1 and the remaining 3 achieved consensus after round 2. Evidence supports computer-aided detection improving adenoma detection rate and miss rate in controlled studies, with mixed real-world impact and insufficient long-term outcomes (e.g., interval colon cancer rate). Recommendations emphasize thorough validation and reduction of bias by heterogeneous Data sets. Outside endoscopy, ambient AI scribes, natural language processing (NLP)-enabled coding, workflow optimization, and previous authorization support show potential. Training recommendations endorse a structured AI curriculum while preserving independent procedural competence to avoid deskilling. In inflammatory bowel disease and hepatology, AI could help improve diagnostic accuracy, help predict risk of disease progression, and help guide therapy. Equity, governance, and reimbursement statements call for chain-of-custody data protections, specialty-society oversight, and payment models that reward quality and cost reduction. DISCUSSION: This consensus outlines how AI can augment rather than replace clinical expertise while promoting safety, transparency, interoperability, and equity. Priorities include pragmatic and prospective trials, multi-institutional data-sharing consortia, bias mitigation, and workforce training to enable trustworthy and clinically impactful AI adoption in gastroenterology, liver, and endoscopy care.

Abstract The phase 1/2 Intergroup study E4412 investigated checkpoint blockade with nivolumab (Nivo) and ipilimumab (Ipi) combined with the CD30 targeting antibody-drug conjugate brentuximab vedotin (BV) in relapsed/refractory classic Hodgkin lymphoma. A total of 147 patients aged ≥12 years were randomized between BV/Nivo and BV/Ipi/Nivo; 132 patients were included in the primary efficacy analysis. The complete response (CR) rate, was 64.7% (52.2, 75.9) for BV/Nivo and 70.3% (57.6, 81.1) for BV/Ipi/Nivo (1-sided P = .29). The median survival follow-up was 38.0 months (interquartile range, 32.6-48.1). Progression-free survival (PFS) did not significantly differ between the 2 arms (hazard ratio [HR], 0.78, confidence interval [CI], 0.39-1.57; 1-sided P = .24). Treatment-related grade 3+ toxicities in the adult cohort, excluding rash, were similar between both arms (38.5% BV/Nivo and 39.3% BV/Ipi/Nivo); there was a higher frequency of grade 3 rash with BV/Ipi/Nivo (24.6%) compared with BV/Nivo (9.2%). We compared PFS by stem cell transplantation (SCT) status in a planned before hoc comparison; 58 patients received SCT, and 36-month PFS (from SCT) was >90% for both arms. Sixty-six patients were progression free after the first scan and did not undergo SCT. The 36-month PFS was 73.0% (54.5, 85.0) for BV/Ipi/Nivo compared with 45.8% (26.3, 63.4) for BV/Nivo (HR, 0.45; CI, 0.19-1.08; 1-sided P = .03). The study did not meet its primary end point of superior CR rate for the triplet, but it supports the use of checkpoint antibody-drug conjugate induction prior to auto SCT, and there is an intriguing signal of disease control for patients wishing to defer or avoid SCT with the triplet of BV/Ipi/Nivo. This trial was registered at www.clinicaltrials.gov as NCT01896999.

ABSTRACT Objectives While maxillary sinus fungal balls (MSFB) can be associated with odontogenic conditions (MSFBO), MSFBO clinical and dental features have not been compared to odontogenic sinusitis (ODS). This multicenter study aimed to compare characteristics of MSFB, MSFBO, and ODS. Methods A multicenter international retrospective cohort study was conducted on adults with MSFBs and ODS who underwent sinus surgery. First in MSFBs, it was determined whether different dental conditions were more likely in FB versus non‐FB sides. Second, clinical features and dental pathologies were compared between MSFBO and ODS. For analyses, dental conditions were considered individually and as two groups: infectious pathologies and dental/oral procedures with indwelling metallic materials. Results After exclusions, there were 203 MSFBs and 163 ODS. Among MSFBs, 141 were MSFBOs. FB sides were associated with sinus protrusion of root canal treatment (RCT) materials ( p = 0.040) and dental implants ( p = 0.040). Compared to MSFBO, ODS patients were younger, more likely to have MS purulence (OR = 40.9, p < 0.010), more likely associated with apical periodontitis (OR = 2.59, p = 0.010) and oroantral fistulas (OR = 6.94, p = 0.020), and less likely associated with extruded RCT materials (OR = 0.01, p = 0.010) and protruded midface screws (OR < 0.01, p = 0.010). Comparing purulent MSFBO and ODS, ODS was more associated with infectious dental pathologies ( p < 0.009). Conclusion Compared to MSFBs, MSFBOs were associated with RCT extrusion and implant protrusion. Compared to MSFBOs, ODS was more likely purulent and associated with infectious dental pathologies. While ODS is often distinct from MSFBO, the two conditions can coexist, and surgeons must determine whether patients have infectious dental pathology requiring treatment with both conditions.

Importance Patients with cancer have high utilization of health care services, and many have high financial burdens from care. High-deductible health plans (HDHPs), which offer lower premiums at the expense of higher deductibles and possibly higher out-of-pocket costs, are associated with decreased care utilization among survivors of cancer. However, it is unclear whether HDHPs are associated with cancer outcomes. Objective To determine whether HDHP status is associated with survival among cancer survivors and individuals without history of cancer and whether financial barriers to care mediate associations between HDHP status and survival. Design, Setting, and Participants This cross-sectional study included US adults ages 18 to 84 years who participated in the National Health Interview Survey from 2011 to 2018. Data were analyzed from December 14, 2023, to December 1, 2025. Exposure HDHP status. Main Outcomes and Measures Outcomes of interest were overall survival (OS) and cancer-specific survival (CSS). Analyses were adjusted for insurance status, marital status, sex, comorbidities, education, household income, geographic region, and cancer site and time since cancer diagnosis (if applicable). Results A total of 147 254 respondents (mean [SD] age, 45.7 [16.4] years; 79 261 [50.9%] female) were identified, including 9799 (5.9%) with history of cancer. A total of 2331 cancer survivors (25.6%) and 37 473 individuals without history of cancer (28.5%) reported an HDHP at the time of NHIS participation. HDHP status was associated with worse OS (hazard ratio [HR], 1.46; 95% CI, 1.19-1.79) and CSS (HR, 1.34; 95% CI, 1.01-1.77) among cancer survivors. In contrast, among adults without history of cancer, HDHP status was not significantly associated with OS (HR, 1.08; 95% CI, 0.96-1.21; P for interaction = .001). In mediation analyses, HDHP status among cancer survivors was associated with increased financial barriers to care, which mediated approximately 30% to 70% of the total association of HDHP with survival. Conclusions and Relevance In this cross-sectional study of nationwide population-based data, HDHPs were associated with worse OS and CSS among cancer survivors. However, HDHPs were not associated with mortality in adults without history of cancer. These data suggest that insurance coverage that financially discourages medical care may financially discourage necessary care and ultimately worsen cancer outcomes.

Abstract Background New insights into community-acquired pleural infection microbiology may enable development of more rapid and accessible diagnostics that can streamline treatment. This study systematically compared molecular approaches for pathogen detection in pleural fluid from patients with such infections. Considering the need for rapid results with minimum hands-on time and test complexity, off-label use of the cassette-based, random-access BIOFIRE Joint Infection Panel (BF-JIP, bioMérieux) with and without supplementary in-house polymerase chain reaction (PCR) assays was evaluated. Methods Pleural fluids from 162 subjects from the Mayo Clinic (Rochester, Minnesota) and Haukeland University Hospital (Bergen, Norway), where molecular tests are routinely used for analyzing pleural fluid, were studied. The performance of the BF-JIP was compared to 16S rRNA gene PCR followed by Sanger and/or next-generation sequencing (16S rRNA gene PCR/sequencing), an in-house PCR panel specifically designed for pleural space infections, and culture. Results The BF-JIP supplemented with 3 in-house PCR assays targeting Fusobacterium nucleatum group, Streptococcus intermedius/constellatus, and Aggregatibacter aphrophilus detected 96.8% of pleural infections, providing complete microbial profiles in 70.1%. In comparison, the detection rate of 16S rRNA gene PCR/sequencing was 92.2%, providing complete microbial profiles in 87.0%. Culture detected bacteria in only 31.9% of pleural fluids, providing complete microbial profiles in 15.3%. Conclusions These results underscore the importance of molecular approaches in diagnosing pleural space infections and demonstrate the feasibility of panel-based PCR-based diagnostics for these sometimes-complex infections. The BF-JIP, designed for testing synovial fluid, could be modified to provide a useful diagnostic for testing pleural fluid.

Objectives: Cerebral hemodynamic impairment in patients with asymptomatic high-grade internal carotid artery (ICA) stenosis confers a risk of stroke and cognitive decline, but correlations between degree of stenosis and hemodynamic impairment are derived from small case series only. Using baseline data from 282 participants in the Carotid Revascularization and Medical Management for Asymptomatic Carotid Stenosis – Hemodynamics (CREST-H) study, we hypothesized that degree of stenosis, measured by peak systolic velocity (PSV) and end diastolic velocity (EDV) in the ipsilateral ICA, would correlate with time-to-peak (TTP) delay using MR (n=275) or CT (n=7) perfusion scans, adjusting for demographic and cardiovascular risk variables. Methods: Using a 7-10MHz Doppler probe, ICA PSV and EDV were assessed. Doppler results were adjudicated centrally. Dynamic contrast perfusion imaging was standardized across 61 CREST-H sites, using sequential T2*-weighted time-sequence scanning (e.g. TR=1500, TE=25ms, flip angle=60deg, phase=128, slice thickness=5mm for GE 3T magnet). CTP was acquired with standard clinical protocols. TTP delay was calculated in the ipsilateral versus contralateral MCA/ACA territories using OLEA software. Linear regression used TTP delay as the outcome variable and PSV and EDV as predictor variables, adjusting for covariates.The 282 with complete data for all variables were included in the analysis. Results: Among 392 CREST-H participants, 63% were men, 7% Black, 3% Hispanic, 33% with less than college education. Tables 1a/b show the regression results for PSV and EDV as main predictor variables. PSV and EDV on the index side significantly correlated with TTP delay (p=0.004, p=0.002 respectively). Neither PSV nor EDV on the non-index side correlated with TTP delay (p=0.49, p=0.82). Compared with moderate exercise, vigorous exercise correlated with lower TTP delay in both models (p=0.05. p=0.04). Compared with college graduates, those with HS education had longer TTP delays in both models (p=0.03. p=0.02). Conclusions: In this large cohort of patients with high-grade asymptomatic carotid stenosis, higher flow velocities correlated with greater TTP delays, suggesting an increasing hemodynamic impairment with greater degree of stenosis above 70%. Our findings have implications for management of asymptomatic carotid stenosis which are being tested in the CREST-H and CREST-2 studies. Exercise and education may independently impact cerebral hemodynamics.

BACKGROUND: Cerebral hemodynamic impairment in patients with asymptomatic high-grade (>70%) internal carotid artery (ICA) stenosis is associated with risk of stroke and cognitive decline, but correlations between the degree of stenosis and hemodynamic impairment are derived from small case series. Using baseline data from 242 participants in the CREST-H study (Carotid Revascularization and Medical Management for Asymptomatic Carotid Stenosis–Hemodynamics), we hypothesized that the degree of stenosis in the ICA would correlate with time-to-peak (TTP) delay in ipsilateral cerebral blood flow using MR/CT perfusion scans, adjusting for demographic and cardiovascular risk variables. METHODS: From all participants, ICAs were insonated using a 7 to 10 MHz probe for peak systolic velocity (PSV) and end diastolic velocity. Dynamic contrast perfusion imaging was standardized across 61 CREST-H sites, using standard sequential T2*-weighted perfusion imaging. CT perfusion used standard clinical protocols. TTP delay was calculated in the ipsilateral versus contralateral hemispheres. In cross-sectional analysis, linear regression was used to model TTP delay as the outcome variable and PSV, end diastolic velocity, and PSV ICA/common carotid artery ratio on the index and nonindex side as primary predictor variables in 6 separate models, adjusting for covariates, followed by automated backward elimination model reduction. RESULTS: Among 392 CREST-H participants, the 242 with complete data for all variables were included in the regression analysis (age, 70±7.6; 62% M). End diastolic velocity on the index side correlated with TTP delay (β=0.003, P =0.005). PSV had a similar correlation but did not reach significance (β=0.001, P =0.099), nor did ICA/common carotid artery ratio (β=0.003, P =0.126). Nonindex side PSV, end diastolic velocity, and ICA/common carotid artery ratio showed no correlation with TTP delay ( P =0.268, P =0.495, P =0.380, respectively). Circle of Willis completeness did not correlate with TTP. CONCLUSIONS: In this large cohort of patients with high-grade asymptomatic carotid stenosis, higher end-diastolic flow velocities correlated with greater TTP delays, supporting a definition of hemodynamically significant stenosis. Our findings have implications for the management of asymptomatic carotid stenosis, which will be tested in the CREST-H study.
