Chimeric antigen receptor T-cell (CAR-T) and CD20xCD3 bispecific antibody (BsAb) therapies are both effective for relapsed/refractory (R/R) follicular lymphoma (FL), but comparative real-world survival outcomes and time toxicity have not been characterized. We performed a multicenter retrospective study of 228 patients with R/R FL treated with standard-of-care CAR-T (n = 141) or BsAb (n = 87) across 17 U.S. academic centers in the third-line or later setting. Progression-free survival (PFS) and overall survival (OS) were stratified by 2 or ≥3 prior lines of therapy (LOT2 or LOT3+), including propensity matching. Time toxicity was measured by physical health care contact days. Median PFS was not reached (NR) with CAR-T and 581 days with BsAb in the LOT2 cohort (p < .0001), and was NR with CAR-T and 584 days with BsAb in the LOT3+ cohort (p = .0064). CAR-T recipients were younger (p < .0001) and had better performance status (p = .007) but were more refractory to prior LOT (p = .017). PFS advantages of CAR-T were independent of these differences. OS did not differ between treatment groups. CAR-T had significantly greater time toxicity over the first year, with higher mean contact days than BsAb in both the LOT2 (58 vs 44) and LOT3+ (69 vs 49) cohorts. In this large multicenter cohort of patients with R/R FL, CAR-T was associated with superior PFS but greater time toxicity compared with BsAb therapy. These findings provide real-world outcomes data and time toxicity benchmarks to support treatment sequencing decision-making in R/R FL.

PURPOSE Patients with breast cancer requiring postmastectomy radiation therapy (PMRT) often desire breast reconstruction. Reconstructions can be adversely affected by PMRT, and fear of reconstruction complications has discouraged adoption of short-course radiation therapy used after lumpectomy. To fill the evidence gap, we conducted a noninferiority trial of hypofractionated versus conventional PMRT in patients undergoing breast reconstruction. The primary outcome was reconstruction complication rate, a composite of wound healing, readmission, capsular contracture, unplanned reoperation, and reconstruction failure. METHODS Women with unilateral invasive breast cancer with planned immediate or delayed reconstruction and PMRT were randomly assigned (1:1) to 50 Gy (25 fractions/5 weeks) or 42.56 Gy (16 fractions/3 weeks). This study was designed with a noninferiority margin of 10%, assuming a 2-year reconstruction complication rate of 25% with conventional PMRT. Randomization was stratified by immediate versus delayed and autologous versus implant-only reconstruction. RESULTS Between 2018 and 2021, 898 patients enrolled with a median follow-up of 3.9 years; 825 patients were evaluable for the primary end point. The 24-month reconstruction complication rates were 12.3% (52/422) with hypofractionated PMRT and 10.2% (41/403) with conventional PMRT, corresponding to an estimated difference of -2.1% (95% CI, -6.5 to 2.2). The complication rate was higher (regardless of arm) with implant-only versus autologous reconstruction (odds ratio = 1.65). There was no statistically significant difference in 36-month locoregional recurrence rates: 1.5% (95% CI, 0.7 to 3.2) with hypofractionated and 2.2% (95% CI, 1.1 to 4.3) with conventional PMRT. Acute and late toxicity rates were not statistically different. CONCLUSION A 16-fraction course of hypofractionated PMRT is safe and noninferior to conventional PMRT in women undergoing breast reconstruction after mastectomy.

Purpose To determine the incidence of cystoid macular edema (CME) within the first 6 months after endothelial keratoplasty (EK) in eyes that had previously undergone vitrectomy versus those without prior vitrectomy. Design Retrospective cohort study. Methods A retrospective cohort analysis of the TriNetX database was performed by querying all patients who underwent EK (Descemet stripping automated endothelial keratoplasty or Descemet membrane endothelial keratoplasty) with ≥ 6 months of follow-up between January 1, 2004, and August 30, 2024. Patients with a previous history of diabetic macular edema, uveitis, or retinal vascular occlusion were excluded. Cohorts were stratified based on a history of prior vitrectomy. Propensity score matching (PSM) between cohorts was conducted for age at index, sex, race, ethnicity, and diagnosis of Fuchs endothelial dystrophy. The outcome assessed was the incidence of postoperative CME within 6 months after EK in both groups. Odds ratios were calculated between cohorts. Results The final analysis included 1044 patients, divided into those with (n = 522) and without (n = 522) prior vitrectomy before EK. Patients who had undergone vitrectomy prior to EK were found to develop postoperative CME within 6 months at a significantly higher rate (32 of 522) compared to those who had not undergone vitrectomy (17 of 522) (P = 0.0282; OR 1.94, 95% CI 1.063–3.539). Conclusion Prior vitrectomy appears to be associated with a greater incidence of postoperative CME after EK.

Purpose: To describe a case of locally invasive conjunctival squamous cell carcinoma (SCC) refractory to plaque radiotherapy. Case Description: A 69-year-old man presented with a recurrent conjunctival tumor after 6 previous cycles of topical 5-fluorouracil chemotherapy and excisional biopsy showing invasive SCC with positive margins. There was a mild anterior chamber reaction. By the time of repeat excisional biopsy, the conjunctiva had ulcerated with underlying scleralysis associated with histopathologic evidence of scleral involvement by SCC. After subsequent tectonic scleral patch grafting, plaque radiotherapy was applied after which the disease appeared to be controlled for 9 months. The eye then developed progressive conjunctival ulceration and scleralysis with progressive ectropion. Exenteration was performed, revealing locally invasive SCC into palpebral conjunctiva, ciliary body, and choroid. Conclusions: Conjunctival SCC can be locally invasive with destruction of the globe, despite plaque radiotherapy. Clinicians should be suspicious of invasive diseases in cases of ocular surface squamous neoplasia that are poorly responsive to topical chemotherapy. Associated anterior chamber cell and progressive scleralysis should also raise concern for invasive malignancy.

Abstract Objective Surgery is an effective, yet underutilized treatment for children with drug‐resistant epilepsy. Although predictors of surgical outcomes are well described, the decision to recommend surgery varies by institution. We aim to evaluate the rates of not recommending surgery, identify associated patient characteristics, and quantify variability across centers. Methods We queried the Pediatric Epilepsy Research Consortium Surgery database, a prospective multicenter cohort of children (0–18 years) undergoing initial evaluation for epilepsy surgery. Patients with documented surgical decisions were included. Demographic, clinical, and presurgical evaluation variables were compared by surgical recommendation status. Logistic regression identified factors associated with not recommending surgery. Mixed‐effects models quantified between‐center variability. Results Among 2480 patients across 29 centers, 532 (21%) were not recommended epilepsy surgery (median center rate 17%, interquartile range [IQR] 10%–28%). After accounting for patient characteristics associated with surgical candidacy, substantial variation in decision‐making remained across centers, with a median twofold difference in the odds of not recommending surgery between otherwise similar patients evaluated at different institutions (Median Odds Ratio = 2.25; Intraclass Correlation Coefficient = .18). The clinical characteristics most strongly associated with not recommending surgery included monthly or less frequent seizures (odds ratio [OR] 2.17, 95% confidence interval [CI] 1.75–2.69), non‐structural etiology (OR 2.02, 95% CI 1.56–2.61), and taking ≤2 anti‐seizure medications (ASMs) (OR 1.67, 95% CI 1.34–2.08, all p 's < .01). These characteristics showed minimal clustering across centers (ICCs < .05). Significance One in five children evaluated for epilepsy surgery are not recommended to pursue surgical treatment. Although clinical factors influence decision‐making, they do not explain the substantial variation in recommendations across pediatric epilepsy centers. Similar children evaluated at different institutions had significant differences in the odds of not being recommended surgery, suggesting that institutional decision‐making contributes importantly to surgical candidacy.

Abstract Introduction Cystoid macular edema (CME) is a recognized complication associated with penetrating keratoplasty (PK) and Endothelial Keratoplasty (EK). The purpose of this study was to determine the incidence of acute CME within the first 6 months after PK, Descemet stripping automated EK, or Descemet’s membrane EK. Methods A retrospective cohort analysis of the TriNetX United States collaborative database was conducted. Patients with a diagnosis of Fuchs dystrophy or keratoconus who underwent PK or EK between January 1, 2004 and August 30, 2024 were included. Those with a history of uveitis, retinal vascular occlusion, diabetic macular edema, or prior vitrectomy were excluded. Outcomes and diagnoses were defined using current procedural terminology and International Classification of Diseases, Tenth edition (ICD-10) codes. Cohorts were stratified based on a history of prior PK or EK with >6 months follow-up. Propensity score matching was performed on both cohorts to control for age at index, sex, race, ethnicity, and the diagnosis of Fuchs dystrophy and keratoconus. The incidence of acute CME during a 6-month postoperative follow-up period was assessed. Odds ratios were calculated between cohorts. Results A total of 2516 eyes were included in the study (PK: 1258; EK: 1258). At six months postoperatively, the incidence of acute CME in the EK cohort (46 of 1258) was significantly higher than in the PK cohort (20 of 1258) (P = 0.0012) (OR 0.426, 95% confidence interval 0.25–0.72). Conclusions Our findings suggest that the incidence of acute CME is higher in patients undergoing EK compared to PK.

Abstract Objective Epilepsy duration is a modifiable risk factor in the outcome of definitive epilepsy surgery; however, an analogous effect in palliative procedures has not been shown. We reviewed the Pediatric Epilepsy Surgery Database data for an association between epilepsy duration and seizure reduction in palliative procedures. Methods Patients enrolled between January 2018 and April 2025 who underwent their first epilepsy surgery with palliative intent with 6 months of follow‐up were included. Procedures included neuromodulation, corpus callosotomy, hemispherotomy, lesionectomy, and lobectomy where surgical intent was not seizure freedom. Outcomes of seizure freedom, 90% seizure reduction, and 50% seizure reduction were considered at 6–12 months and >12 months from surgery. Duration from epilepsy onset to surgery was compared for patients above and below each outcome threshold at each time point. Logistic regression analysis for the association between epilepsy duration and seizure reduction adjusted for potential confounders including procedure type, etiology, and other clinical factors. Logistic regression analysis was performed on the overall cohort and subgroups of patients with each procedure. Results A total of 588 patients were included. Initial univariate analysis suggested that epilepsy duration at time of surgery was significantly associated with seizure freedom and 90% seizure reduction at both 6–12 months and >12 months. After adjusting for confounders, only seizure freedom at >12 months was significantly associated with duration of epilepsy. When individual procedures were considered, only lobectomy was sensitive to duration of epilepsy in multivariate analysis, with significant impacts on >50% and >90% seizure reduction at >12 months. Lesional epilepsy predicted seizure freedom at >12 months. Neuromodulation and corpus callosotomy were less likely to achieve seizure reduction than other procedures. Significance We did not find an association between early epilepsy surgery and seizure reduction. This reflects the heterogeneity of our population, including different types of surgical procedures and lesional and nonlesional epilepsies.

Abstract Objectives Understanding whether the novel long-T ITC complex might assist in interpreting clinical prognostic utility compared to established cardiac biomarkers is needed. We determined long term major adverse cardiac events (MACE) and all-cause mortality (ACM) predicated on novel long-T ITC complex and high sensitivity cardiac troponin I (hs-cTnI) and T (hs-cTnT) assays in the emergency department (ED). Methods cTn assays were measured on the Mindray CL-1200i platform at presentation in consecutive patients enrolled in ‘Mindray hs-cTnI Assay Analytical and Clinical Evaluation for the Diagnosis and RIsk Assessment of Myocardial InfarctIon’ (MERITnI) (NCT05853042) trial with suspected ischemia. Sex specific 99th percentiles upper reference limits (URLs) were: hs-cTnI female 14 ng/L, male 15 ng/L; hs-cTnT female 10 ng/L, male 19 ng/L; long-T ITC complex 0.9 ng/L, same for female and male. Results Of 1,070 patients, 59.4 % were male, 43.4 % White, 45.5 % Black, and 39.5 % ≥65 years. Independent of biomarkers, a continuum of risk over 1 year showed MACE increased to 16.1 % and ACM to 16.5 %. Long-T ITC complex did not show a continuum change, increasing only 0.1 % (HR: 1.001 (1.0–1.001) per ng/L. However, hs-cTnI increased 1.8 % (HR: 1.018 [1.009–1.027] for each ng/L (p<0.0001) and hs-cTnT increased 0.3 % per ng/L (HR: 1.003 [1.001–1.006]) (p=0.0028). Between subjects ≤URLs and >URLs, MACE and ACM all biomarkers showed significant (p<0.0001) differences over 1 year. For MACE in those >URL long-T ITC complex increased 11.2–25.2 %, hs-cTnI 18.0–35.0 % and hs-cTnT 8.9–24.2 %. For ACM in those >URL long-T ITC complex increased 4.5–23.3 %, hs-cTnI 5.0–26.2 %, and hs-cTnT 3.6–24.1 %. Conclusions Novel long-T ITC complex did not provide new prognostic value to either hs-cTnI or hs-cTnT. Patients with increased hs-cTnI and hs-cTnT concentrations had marked increases in MACE and ACM risk at 1-year.

Abstract Background We determined whether circulating cardiac troponin I–cardiac troponin T–troponin C (ITC) complex containing long-form cardiac troponin T (long-T ITC) complex and ratios of high-sensitivity cardiac troponin I (hs-cTnI) and high-sensitivity cardiac troponin T (hs-cTnT) could differentiate myocardial infarction (MI) from chronic and acute non-MI myocardial injuries in patients with suspected acute coronary syndrome. Methods We measured long-T ITC complex, hs-cTnI, and hs-cTnT (Mindray) at 0- and 2-h in consecutive patients enrolled in the Mindray hs-cTnI Assay Analytical and Clinical Evaluation for the Diagnosis and RIsk Assessment of Myocardial InfarctIon (MERITnI) trial. Results Among the 882 subjects studied (median 3.0 h presentation), 47 had acute MI (5.3%), 116 had acute non-MI myocardial injury, and 90 had chronic myocardial injury. At 0 and 2 h, areas under the curve (AUC) significantly differentiated acute MI from chronic myocardial injury for long-T ITC complex (0.72 and 0.81, respectively; P = 0.0082) but not acute non-MI myocardial injury (AUC, 0.65 and 0.69, respectively; P = 0.23). 0 and 2 h AUCs for long-T ITC complex/hs-cTnT and hs-cTnI/hs-cTnT ratios also significantly differentiated acute MI from chronic myocardial injury (AUC, 0.79 and 0.86, respectively) and acute non-MI myocardial injury (AUC, 0.68 and 0.71, respectively). There was no biomarker concentration or ratio value discrimination between type 1 and type 2 MIs. Conclusions Long-T ITC concentrations and long-T ITC complex/hs-cTnT and hs-cTnI/hs-cTnT ratios may clinically assist in differentiating acute MI from non-MI myocardial injuries when evaluating patients with suspected acute coronary syndrome.
