Abstract Background: While synoptic reports have standardized breast cancer data, a wealth of critical information remains locked in unstructured free-text, including nuanced biomarker details and procedural notes. This data is not easily computable, creating a significant barrier to understanding comprehensive population-level statistics and subtle clinical trends. Traditional data extraction methods are often insufficient to capture this complexity. We developed and validated a novel, flexible AI-powered system using an agent-based architecture to extract, normalize, and discretize this valuable unstructured data, enabling previously infeasible population-scale analytics. Methods: Our system employs a modular, agent-based framework where each "agent" is a specialized large language model (LLM) tasked with a specific function in a sequential workflow. The process begins with an initiator agent that parses the synoptic report. Subsequent agents then perform targeted tasks, such as identifying and normalizing tumor characteristics, procedural details, and biomarker information from free-text fields. A final agent aggregates this information into a structured, computable format. To rigorously test our approach, we first developed a synthetic data generator to create realistic, anonymized report snippets with known ground-truth values. We then evaluated the performance of several leading LLMs of various sizes (e.g., gemini, llama3.3, phi4, deepseek-r1, gemma3) on this synthetic dataset. Results: Our early analysis on simulated synoptic reports demonstrated high accuracy in data extraction and normalization. The gemini-1.5-pro-002 model achieved an overall accuracy of 96.9%, with a sensitivity of 99.3%, specificity of 94.3%, and an F1-score of 97.0%. The llama3.3:70b model also showed strong performance with a 98.7% accuracy, (F1: 98.8%, sensitivity: 99.8%, specifically: 97.6%). Gemma3:27b was the least performant model tested (F1: 66.2%), substantially worse than much smaller models (deepseek-r1:1.5b and phi4:14b). A detailed error analysis of false positives and negatives has allowed us to iteratively refine the agent logic. By the time of the symposium, we will have analyzed a large cohort of real, de-identified synoptic reports and will present comprehensive performance metrics and initial findings on population-level trends. Conclusion: This AI-powered, agent-based system offers a powerful and scalable solution to overcome the limitations of structured data in synoptic reports. By accurately extracting and normalizing previously inaccessible free-text information, our approach has the potential to provide clinicians and researchers with near real-time insights into population-level statistics and trends in breast cancer. This will facilitate a more profound understanding of disease patterns and ultimately support evidence-based advancements in patient care and clinical research. Citation Format: S. N. Hart.

Background: This study aimed to determine whether trapezium morphology, specifically trapezial inclination, is a risk factor for the failure of primary conservative or minimally invasive treatment for acute traumatic thumb carpometacarpal (CMC) joint dislocations in the relatively early period. We hypothesized that an elevated trapezial inclination would be associated with a higher rate of treatment failure. Methods: We retrospectively reviewed patients treated for acute thumb CMC joint dislocations between 1976 and 2025 with closed reduction and subsequent immobilization or percutaneous pinning. Patients were classified into “failure” (recurrent dislocation or subsequent symptomatic subluxation) or “non-failure” groups. Trapezial inclination, measured on oblique hand radiographs, was compared between the groups using the Mann-Whitney U test. Results: Fourteen patients met the inclusion criteria (7 failure, 7 non-failure). While demographics were not significantly different, the failure group demonstrated a significantly higher mean trapezial inclination (19.1° vs 8.7°; P = .0012). This significant difference persisted in a subgroup analysis that excluded associated Gedda type 3 Bennett fracture ( P = .0318) Conclusions: Elevated trapezial inclination may predict the failure of primary conservative or minimally invasive treatment in the relatively early period for acute thumb CMC joint dislocation. Our findings suggest that patients with this steep trapezium may be poor candidates for conservative or minimally invasive management and should be considered for primary definitive surgery.

ABSTRACT Interactions between clinical pharmacists and industry partners continue to evolve as health care increases in complexity and technology assumes a more dominant role. To address the corresponding ethical challenges, the 2025 Industry Relations Committee of the American College of Clinical Pharmacy (ACCP) was charged with updating the 2008 ACCP position statement, Pharmacists and Industry: Guidelines for Ethical Interactions . This update expands its perspective, reflecting the broader and more influential roles pharmacists play across the health care ecosystem. All clinical pharmacist–industry interactions should be grounded in improving patient care. Through this lens, six recommendations are provided: (1) Pharmacists should not engage in industry partnerships or collaborations that might unduly influence objectivity, independence, or fairness in clinical and professional judgments; (2) Pharmacists should disclose and mitigate financial, consulting, or other relationships that constitute potential conflicts of interest and should not participate in activities where an existing conflict cannot be resolved; (3) Pharmacists who participate in industry‐sponsored research should follow accepted ethical, regulatory, and scientific standards; (4) Pharmacists providing continuing education programs or developing drug information materials should maintain control of content; ensure their content is fair, balanced, and free from bias; and disclose and mitigate any conflicts; (5) Formal instruction on ethical interactions with industry professionals should begin early and continue through all stages of pharmacist education, training, and professional development; (6) Pharmacists should maintain the confidentiality and privacy of patients and other health care professionals when working with industry partners. Questions to guide personal industry interactions are provided. This paper does not detail every emerging area (e.g., artificial intelligence, social media), but recommendations are applicable wherever clinical pharmacists leverage their professional expertise. By maintaining a critical, discerning, and ethical approach to industry collaborations, clinical pharmacists can uphold professional obligations while contributing to the advancement of evidence‐based practice, ultimately prioritizing patient welfare.

Introduction Craniofacial hyperplasia is a disorder where the face and head do not fully develop. This leads to difficulties in airway management in those undergoing general anesthesia (GA), requiring consideration in anesthetic planning with GA and intubation versus approaches with regional/spinal anesthesia. Case Presentation A 54-year-old male (45 kg, 172.7 cm) presented for a penile implant insertion for severe erectile dysfunction following radical prostatectomy. He was classified as ASA physical status class III. Management and Outcomes Pertinent medical history included craniofacial hypoplasia from childhood surgical interventions and radiation for sinus cancer (rhabdomyosarcoma), moderate mitral regurgitation, mild tricuspid regurgitation, pulmonary hypertension, recurrent esophageal strictures, and anemia. Spinal anesthesia was selected over GA. Airway complications were avoided, and cardiopulmonary stability was preserved while maintaining adequate analgesic coverage. Conclusion Craniofacial hypoplasia patients require individualized anesthesia planning that anticipates complications. Spinal anesthesia can be used in these patients to avoid airway and hemodynamic complications.

Background Corticosteroid injections (CSIs) are widely employed in facet and sacroiliac joint pain. Similar to CSIs at other sites (peripheral nerve blocks, joints, epidural), these injections are associated with potential adverse events. These multisociety consensus recommendations aim to develop evidence-based statements and recommendations on the safe use of CSIs in facet joint and sacroiliac joint injections. Methods Development of the consensus recommendations was approved by the American Society of Regional Anesthesia and Pain Medicine Board of Directors and several other societies that agreed to participate. The scope of statements and recommendations was agreed on to include safety of the injection technique (landmark-guided, ultrasound, or radiology-aided injections); effect of the addition of the corticosteroid on effectiveness (vs local anesthetic or saline); and adverse events related to the injection. Experts were assigned topics to perform a comprehensive literature review and draft statements and recommendations, which were refined and voted for consensus (>75% agreement) using a modified Delphi process. A modified version of the US Preventive Services Task Force grading of evidence and strength of recommendation was followed. Results All statements and recommendations were approved by all participants after four rounds of discussion. The Practice Guidelines Committees and Boards of Directors of the participating societies also approved all statements and recommendations. Injection of corticosteroid into the facet joint in patients with joint inflammation may relieve pain and improves function. Intra-articular, extra-articular (periarticular), and combined administration are effective for sacroiliac joint injections. No dose-response studies exist, but CSIs containing 10 mg of methylprednisolone or triamcinolone per facet joint and 40 mg per sacroiliac joint (SIJ) (or their respective pharmacologic equivalents) are reasonable. Conclusions In this practice recommendation, we provide statements and recommendations on facet and sacroiliac joint CSIs, the optimal doses, and intervals and criteria for repeating the CSIs in patients with facet joint and sacroiliac joint pain.

Abstract Background: DNA methyltransferase (DNMT) isoforms 1, 3A and 3B are enzymes that regulate DNA methylation, controlling gene expression, chromatin stability and genetic imprinting. We have previously shown that DNMT3A protein expression in early triple negative breast cancer (TNBC) is associated with more aggressive clinicopathologic features (higher tumor grade, tumor proliferation and frequency of nodal metastases) and worse clinical outcomes in the absence of chemotherapy (Leon-Ferre et al, SABCS 2024). Pre-clinically, we have shown that DNMT3A protein expression predicts sensitivity to DNMT inhibitors (Yu J et al., J Clin Invest 2018), and that DNMT inhibitor treatment leads to downregulation of DNMT3A, enhanced expression of immune-related pathways, and halted tumor growth, particularly in combination with immunotherapy and paclitaxel. Methods: This is a phase 1, open-label, multicenter study evaluating the safety and recommended phase 2 dose (RP2D) of the oral DNMT inhibitor ASTX727 + paclitaxel + pembrolizumab in metastatic TNBC. ASTX727 is an oral fixed dose combination (FDC) tablet of 35 mg decitabine (active agent) and 100 mg cedazuridine (a cytidine deaminase inhibitor that prevents decitabine degradation in the bowel and liver, allowing oral delivery). The study consists of two parts: Part 1 is a dose-finding cohort, using a 3+3 design, with 5 dose levels (Table), and its primary objective is to determine the RP2D. Part 2 is an expansion cohort (n=6), with the primary objective to confirm tolerability of the regimen at the RP2D. Secondary objectives are to record the antitumor activity of the regimen, describe the AE profile, explore the association of baseline gene expression profiles with clinical benefit, and to evaluate impact of treatment on tumor and ctDNA methylation. Exploratory objectives will evaluate the association of baseline DNMT3A protein expression and antitumor activity, and the impact of treatment on the tumor and peripheral blood immune phenotype. Eligible patients are adults 18 years or older with metastatic TNBC (ER/PR ≤10%, and HER2-negative per ASCO/CAP guidelines), independent of PD-L1 expression. Patients are allowed to have received 0-3 prior lines of systemic therapy in the metastatic setting, including prior immune checkpoint inhibitors in the early and/or metastatic settings. Patients must be eligible for taxanes and have adequate organ and bone marrow function. Patients with treated brain metastases are eligible if previously treated without evidence of progression after 4 weeks. Leptomeningeal carcinomatosis is not allowed. Patients must have an ECOG performance status of ≤2 and have no gastrointestinal disorders impacting absorption of oral medications. As of June 20, 2025, the study is enrolling patients, with 10 patients dosed in the dose-finding phase. Citation Format: R. Leon-Ferre, D. M. Zahrieh, P. P. Advani, D. Quiroga, K. V. Giridhar, P. J.

Abstract Background: Endocrine therapy (ET) with aromatase inhibitors (AIs) plus ovarian function suppression (OFS) is a standard endocrine strategy for premenopausal women with ER+/HER2- breast cancer. However, poor tolerability to AI+OFS limits its use, leaving tamoxifen as the only alternative. Prospective studies demonstrated that premenopausal women treated with neoadjuvant ET whose tumors exhibit Ki-67 ≤ 10% following 4 weeks of therapy achieve 5-year distant disease-free survival > 96%. Problematically, only 41% of patients reach this threshold with tamoxifen compared to 78% with AI+OFS (Nitz JCO 2022). (Z)-endoxifen (ENDX) is a potent selective estrogen receptor modulator that dually targets ERα and PKCβ1. At plasma concentrations of 3-5 ng/mL, it inhibits ERα; at ≥ 500 ng/mL, it targets PKCβ1, leading to AKT suppression. The EVANGELINE trial aims to examine endocrine sensitivity in terms of Week 4 Ki-67 in premenopausal women whose baseline Ki-67 > 10%, and objective response rate after 24 weeks of ENDX + goserelin in premenopausal women with baseline Ki-67≤ 10%. Methods: EVANGELINE (NCT05607004) is a multicenter, open-label, Phase 2 study comprised of three parts. Eligible patients are premenopausal women with Stage IIA/IIB ER+/HER2- breast cancer. • Part 1 (PK Run-in): assessed 40mg vs 80mg ENDX (+/- OFS) in 22 patients. • Part 2: patients with baseline Ki-67 >10% were randomized to 40 mg ENDX + goserelin or exemestane + goserelin for 6 months with the primary objective being 4-week ESD rate. Patients with a baseline Ki-67 ≤10% were assigned to a single-arm cohort of 40 mg ENDX monotherapy (no OFS) to evaluate the 24-week endocrine sensitivity disease rate. • Part 3 (replaces Part 2): all patients are treated with ENDX 40mg daily + goserelin every 28 days. A two stage Phase II design was chosen to assess outcomes as follows: Part 3a: Up to 45 patients with baseline Ki-67> 10% to assess Week 4 Ki-67≤ 10% rate is at least 65%. If 9 or more of these patients have a Week 4 Ki-67>10%, enrollment will be stopped due to futility. Otherwise, enrollment will continue. Part 3b: Up to 20 patients enrolled with baseline Ki-67≤ 10% to assess Week 24 objective response rate. Ki-67 levels are determined by central laboratory and images are centrally reviewed. Secondary objectives include safety, tolerability, surgical outcomes, and biomarker analysis using paired biopsies (baseline, week 4) and surgical specimens. Results: The PK run-in (completed Fall 2024) enrolled 22 patients and assessed ENDX doses (40 mg daily vs 80 mg daily (+/-OFS)). The Week 4 Ki-67 ≤ 10% rate with ENDX was 86% and did not differ according to dose. Early safety, PK, efficacy and compliance data supported the selection of 40 mg ENDX daily as the optimal dose. Enrollment in Part 2 began in May 2025. Part 3 will replace Part 2 with simplification of the trial design. Conclusions: EVANGELINE is the first trial to evaluate (Z)-endoxifen + OFS as neoadjuvant therapy in premenopausal ER+/HER2- breast cancer. By targeting both ER and PKC pathways, ENDX may offer a well-tolerated alternative to AI-based regimens and expand endocrine therapy options for this population.

ABSTRACT Background and Aims Cellular senescence is a hallmark of several liver diseases, including primary sclerosing cholangitis (PSC) and primary biliary cholangitis (PBC). Senescent cholangiocytes exhibit a senescence‐associated secretory phenotype (SASP), characterized by profibroinflammatory mediator release. Current cost‐effective biomarkers predicting disease progression, particularly for PSC, are limited and often lack mechanistic relevance. We sought to define a plasma biomarker signature for PSC and PBC. Methods Plasma from early‐ and late‐stage PSC and PBC, alcoholic liver disease (ALD), inflammatory bowel disease (IBD) patients, and healthy controls was analyzed. Seventy‐one analytes were quantified using Luminex Multiplex Immunoassay or enzyme‐linked immunosorbent assay (ELISA). Principal component analysis (PCA) identified key patterns. Findings from the PSC cohort were then applied to additional cohorts. Results Second principal component (PC2) (17 analytes, 17.1% variability) best separated PSC from controls. ANOVA showed significant differences in PC2 between early PSC vs. controls ( p = 0.0001), late PSC vs. controls ( p < 0.0001), and early vs. late PSC ( p < 0.0001). PC2 analytes also distinguished early PBC vs. controls ( p < 0.0332), late PBC ( p < 0.0001), and ALD ( p < 0.0001), and early vs. late PBC ( p < 0.0001), but not IBD vs. controls ( p = 0.119). Logistic regression using PC2 demonstrated strong discrimination of early‐ and late‐stage PSC (AUC = 0.86) and control vs. early‐stage PSC (AUC = 0.83). Conclusion This is the first study to define a plasma SASP biomarker signature associated with cholestatic liver disease. These analytes track disease stage and represent both mechanistic indicators and potential clinical trial endpoints.

Importance Patients with recurrent prostate cancer after previous radiotherapy typically have poor survival. Those with recurrences prostate confined might be suitable for salvage focal therapy (sFT) or salvage radical prostatectomy (sRP). sFT may offer good cancer control with comparatively less toxic effects, but outcomes beyond 5 years have not been reported, and no study has compared sFT to sRP. Objective To compare cancer control and perioperative complications among patients after sFT vs sRP. Design, Setting, and Participants In this international, multicenter cohort study of matched comparison data, patients undergoing sFT were derived from the prospective UK HIFU (high-intensity focused ultrasound) Evaluation and Treatment and International Cryotherapy Evaluation registries (9 centers; 2006-2024) and the prospective UK Focal Recurrent Assessment and Salvage Treatment cohort study (6 centers; 2014-2018). Patients undergoing sRP were derived from an international retrospective registry (12 centers in 8 countries; 2000-2021). Patients with biopsy-confirmed, localized recurrent prostate cancer postradiotherapy, either external beam radiotherapy, brachytherapy, or both, were included. Data were analyzed from March to July 2025. Exposures sFT using HIFU or cryotherapy vs sRP. Main Outcomes and Measures The primary outcome was cancer-specific survival up to 10 years. Secondary outcomes were overall survival, any perioperative complications (Clavien-Dindo grades 1-5), and major perioperative complications (Clavien-Dindo grades 3-5). Comparisons were made on matched patients following 1:1 cardinality matching within individual multiply-imputed datasets. Matching variables used were radiotherapeutic treatment, years between primary and salvage treatments, European Association of Urology recurrence risk group, and presalvage age, prostate-specific antigen, prostate volume, grade group, T stage, and androgen-deprivation therapy use. Results A total of 923 patients were eligible for matching (419 undergoing sFT and 504 undergoing sRP). Of the patients undergoing sFT, 325 (77.6%) underwent HIFU and the remainder cryotherapy, with 241 (57.5%) treated with quadrant ablation. Of patients treated with sRP, 376 (74.6%) underwent open surgery and the remainder robot-assisted surgery. For sFT vs sRP, 10-year cancer-specific survival was 92% (95% CI, 86%-98%) vs 99% (95% CI, 97%-100%), with no statistically significant difference (restricted mean time lost, −0.09 years; 95% CI, −0.22 to 0.03 years; P = .15; subdistribution hazard ratio, 0.45; 95% CI, 0.05-4.00; P = .47). There was no statistically significant difference in 10-year overall survival (restricted mean survival time, −0.13 years; 95% CI, −0.86 to 0.60 years; P = .72). Undergoing sRP was associated with statistically significant higher odds of any complication (adjusted odds ratio, 24.20; 95% CI, 12.94-45.27; P &amp;lt; .001) and major complication (adjusted odds ratio, 9.31; 95% CI, 3.42-25.36; P &amp;lt; .001). Conclusions and Relevance In this cohort study, sFT and sRP were effective for treating localized radiorecurrent prostate cancer, while sFT was associated with fewer perioperative complications. sFT may provide a favorable therapeutic ratio for many patients with localized radiorecurrent prostate cancer.

Abstract The human X chromosome accounts for ∼5% of the genome. Despite its size, the role of X-chromosomal variants in human diseases is not well understood, mainly due to its distinct inheritance pattern and the frequent omission of sex chromosomes from genome-wide association studies. This study used whole-genome sequencing data from 888 multiple system atrophy (MSA) cases and 7128 controls to perform an X-chromosome-wide common variant association study. Our analyses revealed two sex-differential risk loci: one located at Xq28, associated with increased risk for MSA in females [index variant: rs4898389, odds ratio (OR) = 1.69, 95% confidence interval (CI) = 1.40–2.03, P-value = 2.43 × 10⁻⁸], and another at Xp22.2 within the TBL1X gene, identified in males (index variant: rs6638956, OR = 1.48, 95%CI = 1.26–1.73, P-value = 9.92 × 10⁻⁷). In the Xq28 locus, colocalization analyses pointed to FAM3A and PLXNA3 as genes of interest. These findings emphasize the vital role of sex-differential genetic factors in the pathogenesis of MSA.
