12010 Background: BWEL (Alliance A011401; NCT02750826) is a Phase III trial that randomizes patients (pts) with stage II-III breast cancer and body mass index (BMI) ≥27 kg/m 2 1:1 to a 24-month (mo) lifestyle-based WLI + health education (HE) or HE alone. Here we report prespecified secondary outcomes of the impact of the WLI on patient-reported QOL and symptoms. Methods: The first 540 BWEL pts (randomized between 9/2016 and 7/2017) were included in this substudy that collected PROMIS 29 Profile 2.0 and Global Health scores at enrollment, 6 and 24 mos. Adjusting for baseline scores, mean physical function (predefined substudy primary outcome), global physical and mental health, fatigue and other scores were compared at 6 and 24 mos using analysis of covariance (ANCOVA). P-values <0.05 were considered significant. Positive differences in positive attributes (e.g., physical function) and negative differences in negative attributes (e.g., anxiety) represented better outcomes in the WLI arm. Results: At baseline, median BMI was 32.9 kg/m 2 (26.5 – 69.1), median age was 53 (25 - 78) years; 83.9% of pts were non-Hispanic White, 10.7% were Black and 5.9% were Hispanic. At 6 mos, the WLI (vs HE) arm had significantly better physical function (ANCOVA-based mean difference between arms 1.9 [95% CI 0.8, 3.0]; p<0.001), global physical health (2.0 [95% CI 0.9, 3.0]; p<0.001), global mental health (1.30 [95% CI 0.2, 2.4], p=0.03), social roles and activities (2.3 [95% CI 1.1, 3.6]; p<0.001), and fatigue (-1.7 [95% CI -3.1, -0.4], p=0.01) (Table). Improvements were generally maintained at 24 mos. Similar findings were seen in analyses using longitudinal mixed modeling. Conclusions: The BWEL WLI demonstrated QOL benefits for patients with breast cancer, resulting in significantly better physical function, global physical and mental health, and symptoms. Future analyses will evaluate which populations experienced the most benefit, as well as the relationships among QOL, symptoms, and weight loss.

Telehealth may improve access to specialized oncology care for Medicaid beneficiaries with hematological malignancies who face geographic and financial barriers. During the COVID-19 public health emergency, telehealth use expanded rapidly, yet state policies governing telehealth coverage/payment parity varied. Evidence is limited on how these policy differences influenced oncology telehealth use for Medicaid patients. We conducted a cross-sectional analysis of 2020–2021 multistate Medicaid claims. Adult and pediatric oncology specialists were identified based on board certification data. Telehealth video visits were measured monthly at the extensive margin, defined as the proportion of specialists providing any telehealth, and the intensive margin, defined as average monthly telehealth visits among telehealth providing specialists. States were categorized by private insurance telehealth policy environment: coverage and payment parity, coverage parity only, or no or unspecified parity. Telehealth use increased sharply across all states in early 2020, rising from less than 1% of specialists before the pandemic to peak levels by April 2020. Specialists practicing in coverage and payment parity states demonstrated higher and more sustained telehealth use through 2021 compared with those in coverage only or no parity states. By December 2021, 15.1% of adult specialists in coverage and payment parity states provided telehealth, compared with 8.1% in coverage-only states and 7.8% in no-parity states. Pediatric specialists showed similar patterns, though overall telehealth use remained lower. Specialists in parity states also maintained higher monthly telehealth visit volumes over time. State-level coverage and payment parity policies may have been associated with greater and sustained telehealth provision by oncology specialists treating Medicaid beneficiaries with hematologic malignancies. Maintaining supportive telehealth policies may be essential for promoting equitable access to specialized cancer care and reducing disparities among underserved populations. These findings inform future telehealth policy decisions nationally statewide.

Background: The purpose of this study was to describe, and report the outcomes of, a surgical technique that combines reverse shoulder arthroplasty (RSA) using an allograft-prosthetic composite (APC) with a lower trapezius transfer (LTT) to the infraspinatus of the allograft extended with the inferior capsule. Methods: Between 2019 and 2023, 2 surgeons performed a total of 27 RSAs using an APC in conjunction with an LTT. Once the RSA APC reconstruction had been performed, cuff-capsule allograft tissue was passed posterior to the glenosphere and secured to the harvested lower trapezius. One shoulder was resected for periprosthetic joint infection; the remaining 26 shoulders were followed for a minimum of 2 years (mean, 2.7 years; range, 2 to 5 years). Results: The rate of revision or reoperation for humeral complications was 15% and included secondary bone grafting (2 shoulders), resection for infection (1 shoulder), and internal fixation of a periprosthetic fracture (1 shoulder). Other complications requiring surgery included hematoma treated with evacuation (2 shoulders), dislocation (1 shoulder), and glenosphere disassociation (1 shoulder). Preoperatively, 11 shoulders presented with pseudoparalysis, and the mean active elevation of the remaining 16 shoulders was 43°, with only 1 shoulder demonstrating >90° of active elevation. At the most recent follow-up, 3 shoulders were pseudoparalytic, 11 had <90° of active elevation, 8 had >90° of active elevation, and 3 had active elevation to 90°. The overall mean active elevation of the 25 shoulders that could be assessed was 79°. Preoperatively, only 4 (15%) of the 27 shoulders demonstrated active external rotation past neutral; at the most recent follow-up, 80% of surviving shoulders had active external rotation past neutral. Conclusions: LTT at the time of RSA using an APC has the potential to restore active external rotation in shoulders with proximal humeral bone loss and posterosuperior cuff deficiency.

Introduction To assess the within-class variation in kidney outcomes following initiation of sulfonylurea therapy. Research design and methods We used claims data of enrollees in commercial, Medicare Advantage, and traditional Medicare health plans between 2014 and 2021 to emulate a target trial including adults ≥21 years with type 2 diabetes at moderate cardiovascular risk to compare initiation of glimepiride, glipizide, or glyburide on the incidence of chronic kidney disease (CKD) stage 3 or worse, including initiation of kidney replacement therapy (primary outcome); secondary outcomes examined incident CKD stages 3-4, kidney failure (including kidney replacement therapy), all-cause mortality, and hypoglycemia requiring emergency department or hospital care. Random treatment assignment was emulated using propensity scores, estimated using the super learner ensemble method, and incorporated as inverse probability of treatment weights into proportional hazards models. Results The weighted study cohort included 295 092 individuals starting glimepiride (n=134 926), glipizide (n=145 984), and glyburide (n=14 182). One year after treatment initiation, stage 3 or worse CKD developed in 2.1% of patients in the glimepiride group, 2.2% in the glipizide group, and 1.8% in the glyburide group. Glyburide was associated with a lower risk of kidney complications compared with both glimepiride (HR 0.84, 95% CI 0.76 to 0.92) and glipizide (HR 0.81, 95% CI 0.73 to 0.89), despite a higher risk of severe hypoglycemia (HR 1.47, 95% CI 1.27 to 1.71 vs glipizide and HR 1.22, 95% CI 1.05 to 1.42 vs glimepiride). In contrast, the risk of kidney complications was modestly increased with glipizide compared with glimepiride use (HR 1.04, 95% CI 1.00 to 1.07). Conclusions Glyburide was associated with a modestly lower risk of kidney complications, despite a higher risk of hypoglycemia, while glipizide was associated with a higher risk of kidney complications. These hypothesis-generating findings suggest important within-class differences that warrant consideration in clinical decision-making and future research. Despite rigorous prespecified causal inference analytic methods, the risk of unmeasured confounding and bias by indication with the use of observational data remains.

Abstract Background Vorasidenib is Food and Drug Administration‐approved for treatment of grade 2 isocitrate dehydrogenase (IDH)–mutant gliomas and has demonstrated a benefit in progression‐free survival compared to a placebo. This study assessed the cost‐effectiveness of this treatment strategy compared to standard treatment: observation or chemoradiation (CRT). Methods The authors used an integrated Markov model to compare quality‐adjusted life‐years (QALY) gained and cost‐effectiveness of patients with IDH‐mutated low‐grade glioma (LGG) treated with vorasidenib, observation, or CRT. Outcomes were expressed as incremental cost‐effectiveness ratios (ICERs) per QALY gained. Treatment is considered cost‐effective if it meets the commonly accepted willingness‐to‐pay threshold of $100,000 per QALY gained. Results Based on model parameters, vorasidenib demonstrated an ICER of $356,756 per QALY when compared to CRT. When compared to observation, vorasidenib demonstrated an improved ICER of $215,191 per QALY. On one‐way sensitivity analysis compared to observation, median cost of vorasidenib and median overall survival were most likely to affect ICER with only marginal changes on analysis of other model factors. For ICER to become ≤$100,000 compared to observation, the cost of vorasidenib would need to drop to below $14,072 monthly or have a median survival gain of at least 11.9 years. The probabilistic sensitivity analysis demonstrated that vorasidenib was favored in none of 5000 Monte Carlo iterations. Conclusion Using the best available data, the current price of vorasidenib does not meet commonly accepted cost‐effectiveness thresholds in treatment of IDH‐mutated LGGs.

Expert consensus recommendations from 21 academic centers were established for appropriate radiography utilization at 12 potentially low-yield anatomic sites through a multidisciplinary process endorsed by six major American medical societies.

Objective(s): To (1) report on the long-term recurrence rate of surgically managed pleomorphic adenoma (PA) and (2) assess long-term surgical outcomes after parotidectomy Methods: Cross-sectional survey of all patients with a pathologic diagnosis of PA who underwent surgical management in a tertiary care center from 01/1997 to 12/2023 and had access to an electronic patient portal. Surveys were delivered via electronic patient portal or phone call with 6 questions to assess recurrence and long-term surgical outcomes. Time to first recurrence and recurrence free survival were analyzed using a Kaplan-Meier curve. Results: Seven hundred-forty-five patients met inclusion criteria and received the survey, with a 56% response rate (n = 420). The clinical median follow-up length was 51 days, which extended to a median length of 6.2 years following the survey. The median change in follow-up length was 5.37 years ( P < .001). The recurrence rate was 1% at 5 years, with a median time to first recurrence of 7.54 years. 13% and 9% of responders reported facial asymmetry and incisional cosmetic concerns, respectively. 33% of patients reported experiencing Frey syndrome, which increased from 5.2% of survey responders with documented Frey syndrome at their original post-operative assessment. Conclusion: Long-term assessment of PA outcomes confirms low recurrence rates, suggesting regular surveillance of recurrence is likely unnecessary. Complaints of Frey syndrome increased in frequency with longer term follow-up, which should be considered during patient counseling. Level of Evidence: 3

Abstract Introduction Nuclear protein in testis (NUT) carcinoma, formerly known as NUT midline carcinoma, is a rare and highly aggressive subtype of squamous cell carcinoma characterized by NUTM1 gene rearrangements. It typically affects children and young adults and shows a predilection for midline structures of the head, neck, and thorax. We describe a rare case of NUT carcinoma in an elderly patient presenting with central airway obstruction treated with tumor debulking, devascularization, and pulsed electric field (PEF) ablation. Case An 89-year-old woman on chronic anticoagulation for atrial fibrillation presented with respiratory distress and hemoptysis requiring intubation and mechanical ventilation. Chest CT revealed a developing right lower lobe infiltrate and bronchoscopy demonstrated a non-obstructing right lower lobe endobronchial lesion. Pathology of the lesion confirmed NUT carcinoma but the patient was lost to follow-up. Two months later, she presented with altered mental status and respiratory failure. Imaging revealed a 4.6 x 2.6 cm mass at the level of the cricoid cartilage causing approximately 75% tracheal obstruction with tracheal wall invasion. She underwent rigid bronchoscopy with tumor debulking and devascularization, achieving &gt;80% tracheal patency post-procedure. EBUS-guided PEF ablation was then performed to target residual bulky tumor found in the paratracheal area. Given her age, comorbidities, and poor performance status, palliative chemotherapy was deferred and palliative radiotherapy was offered to limit tumor progression. Discussion NUT carcinoma is a rare and aggressive malignancy with a poor prognosis. This case demonstrates rapid tumor progression leading to respiratory failure within two months of initial diagnosis. Management options for malignant central airway obstruction in non-surgical candidates may include endobronchial debulking and ablative therapies. In this case, EBUS-guided PEF ablation, a non-thermal technique that delivers brief electric pulses to induce tumor apoptosis while sparing adjacent structures, was successfully used to treat residual disease with the goal of reducing marginal regrowth and maintain airway patency. PEF ablation has been described in percutaneous and bronchoscopic management of early stage non-small cell lung cancer; however, its application in central airway obstruction represents an innovative therapeutic approach. Although chemoradiation may be considered when feasible, no standard regimen exists for NUT carcinoma. It typically responds poorly to conventional therapies, underscoring the importance of complementary local treatment strategies in select patients. This case highlights the rapidly progressive course of NUT carcinoma and demonstrates the potential role of PEF ablation as a novel adjunct in the palliative management of malignant central airway obstruction.
