Descemet Stripping Only in Fuchs Endothelial Corneal Dystrophy: Results of a Randomized Clinical Trial of Topical Ripasudil and Directions for Future Innovation.

PURPOSE: To review history of Descemet stripping only (DSO) in Fuchs endothelial corneal dystrophy, describe the results of a clinical trial of topical ripasudil after DSO (K-321-201 study), and discuss future directions. METHODS: A 1-year, phase 2, randomized, placebo-controlled multicenter clinical trial of two doses of K-321 (ripasudil) administered for 12 weeks after DSO surgery in Fuchs endothelial corneal dystrophy was performed. The primary endpoint, central corneal endothelial cell density (ECD) at 12 weeks after surgery, was determined by an independent reading center that was masked to study group assignment. Duration of corneal edema, need for medical or surgical rescue therapy, corneal thickness, and central ECD throughout the entire study period were also examined. Adverse events and exploratory endpoints were collected. RESULTS: Sixty-five subjects were enrolled (21 in the QID group, 22 in the BID, and in the placebo group). Over 95% of subjects completed the trial. The QID group had a higher central ECD 12 weeks after DSO than the placebo group (531 ± 312 cells/mm2 vs 228 ± 298 cells/mm2, P = .0065). Corneal edema cleared in 17/21 (81.0%) of the QID group at 12 weeks, compared with 2/22 (9.1%) of the placebo group (P < .0001). Rescue was required in 2/21 (9.5%) subjects in the QID group and 6/22 (27.3%) subjects in the placebo group (P = .0092). Adverse events were mild and did not lead to discontinuation of treatment. CONCLUSIONS: Topical K-321 given QID improves DSO outcomes, as demonstrated by a higher ECD, more rapid resolution of corneal edema, and reduced failure rate. The medication was well-tolerated.

Aortoesophageal Fistula: Mending the Lethal Connection-A Systematic Review and Meta-Analysis.

BACKGROUND: Aortoesophageal fistula (AEF) is a rare, life-threatening condition with limited high-quality evidence to guide management. METHODS: We conducted a systematic review and meta-analysis of PubMed and Scopus through December 2025, evaluating survival and complication outcomes according to treatment strategy and morphological severity. Patients were categorized into 5 groups: TEVAR alone, staged TEVAR followed by surgery, primary open or hybrid surgery, TEVAR with esophageal stenting, and supportive/palliative care. Outcomes were pooled as proportions with 95% confidence intervals (CIs). RESULTS: A total of 167 reports representing 528 patients were included. Overall 30-day mortality was 31.2% (95% CI 27.0% to 35.7%) and 1-year mortality 41.2% (95% CI 36.2% to 46.4%). Infection occurred in 32.6%, reintervention in 20.2%, and recurrence in 13.2%. Staged TEVAR followed by surgery showed favorable survival (30-day 12.7%, 1-year 26.1%) but high infection (66.7%) and reintervention (43.2%) rates. TEVAR with esophageal stenting had the lowest early mortality (5.0%) but frequent reintervention (54.5%) and 1-year mortality of 33.3%. TEVAR alone demonstrated the lowest 1-year mortality among definitive strategies (25.5%) but notable recurrence (26.9%). Primary open or hybrid surgery carried higher early and late mortality, while supportive/palliative care had the worst outcomes. Morphological severity correlated strongly with mortality, infection, reintervention, and recurrence, with type IV lesions showing particularly poor prognosis. CONCLUSION: Despite contemporary management, AEF carries high early and late mortality. Definitive strategies, particularly staged TEVAR followed by surgery, offer improved survival but increased complications. Morphology-guided, individualized management is recommended.

Prognostic Value of Frailty in Aortic Surgery: A Systematic Review and Meta-Analysis Comparing Frailty Assessment Tools.

BACKGROUND: Frailty is increasingly recognized as an important determinant of outcomes after aortic vascular surgery, but assessment methods vary substantially and the optimal tool for risk stratification remains uncertain. This systematic review and meta-analysis evaluated the prognostic value of preoperative frailty and compared the predictive performance of different frailty instruments in aortic surgery. METHODS: PubMed, Embase, and Cochrane Library were searched from inception to April 27, 2026. Eligible studies included patients undergoing open, endovascular, or hybrid aortic procedures involving abdominal, thoracic, thoracoabdominal, arch, and proximal aortic diseases, including aneurysms and dissections, assessed frailty preoperatively, and reported postoperative outcomes. RESULTS: Thirty studies comprising 419,459 patients were included. Frailty was associated with higher early mortality (odds ratio [OR] 2.20; 95% confidence interval [CI] 1.54-3.14) and late mortality (hazard ratio 2.18; 95% CI 1.64-2.90). Frail patients also had increased risks of major complications (OR 2.52; 95% CI 1.22-5.19), acute kidney injury (OR 1.64; 95% CI 1.34-2.02), and nonhome discharge (OR 5.50; 95% CI 3.05-9.92). Associations were consistent across surgical approaches and aortic segments. Judgment-based or phenotype-like tools yielded higher effect estimates than deficit-accumulation indices, although differences were not statistically significant; among index-based tools, Modified Frailty Index (mFI)-11 outperformed mFI-5. CONCLUSION: Preoperative frailty strongly predicts mortality, morbidity, and loss of functional independence after open, endovascular, and hybrid aortic surgery across different aortic segments and pathologies, including aneurysmal and dissecting aortic disease. Routine frailty assessment may improve risk stratification and perioperative decision-making.

Sex-specific biomarkers predict bone mineral density loss at the contralateral hip after hip fracture.

OBJECTIVE: To identify inflammatory and hormonal biomarkers that predict bone loss at the contralateral (non-fractured) hip following hip fracture in males and females. METHODS: White participants who were not receiving pre-fracture glucocorticoids, sex-hormone therapy, or bone-active medications (100 males, 76 females) with hip fractures. Data were collected within 22 days of hip fracture and at 2, 6, and 12 months follow-up. Biomarkers were categorized into tertiles: estradiol, 25-hydroxyvitamin D3/D2, intact parathyroid hormone (iPTH), interleukin-1 receptor antagonist (IL-1RA), interleukin-6 (IL-6), insulin-like growth factor-1 (IGF-1), soluble tumor necrosis factor-α receptor 1, sex hormone-binding globulin, and testosterone. Femoral neck bone mineral density (BMD) at the contralateral hip was assessed, and losses exceeding the mean decline were classified as greater than average. Logistic regression models, stratified by sex, were adjusted for confounders and evaluated selected biomarker associations. RESULTS: Among males, the 2nd (OR = 4.79, P = 0.012) and 3rd (OR = 6.36, P = 0.005) IGF-1 tertiles were associated with greater odds of BMD loss than the 1st tertile. The 3rd iPTH tertile (OR = 3.79, P = 0.037) was similarly associated with increased odds. Among females, the 3rd (OR = 0.20, P = 0.031) IL-1RA tertile was associated with lower odds of BMD loss compared to the 1st tertile, while the 2nd IL-6 tertile (OR = 5.99, P = 0.036) was associated with higher odds. CONCLUSION: These findings suggest that inflammatory and hormonal biomarkers may be sex-specific predictors of accelerated BMD loss following hip fracture.

Accelerating Lung Cancer Management Through Previsit Liquid Biopsy: Results From the LUNG-FAST Pilot Study.

BACKGROUND: Timely molecular profiling is essential for treatment selection in non-small cell lung cancer (NSCLC), yet delays in biomarker testing remain common. We evaluated the feasibility and early clinical impact of a nurse navigator-driven workflow to initiate liquid biopsy before the initial oncology visit. METHODS: LUNG-FAST (Liquid Biopsy for Urgent Neoplastic Genomic Profiling Focused Accelerated Stratification and Testing) was a 4-month prospective pilot at a tertiary cancer center. Intake nurse navigators identified eligible patients with suspected or newly diagnosed lung cancer and facilitated previsit liquid biopsy ordering. Feasibility, turnaround times, genomic findings, and early clinical outcomes were assessed. RESULTS: Among 64 patients, intake nurse navigators identified 94% (60/64) of eligible cases. Liquid biopsy was ordered in 58 patients, with 62% (36/58) placed before the initial oncology visit. Median turnaround time from blood draw to results was 8.5 days for commercial testing and 12.5 days for institutional testing. FDA-actionable genomic alterations were identified in 34% (22/64) of patients, while an additional 11% (7/64) harbored clinically relevant, non-FDA-actionable alterations. Overall, FDA-actionable or clinically relevant alterations were identified in 45% (29/64), with 22% detected by liquid biopsy and an additional 23% by tissue-only profiling. Median time from new patient visit to systemic therapy was 26 days. CONCLUSIONS: A nurse navigator-driven workflow enabling previsit liquid biopsy is feasible and identifies actionable genomic alterations in a substantial proportion of patients with lung cancer. Plasma and tissue profiling are complementary, and earlier plasma-based testing may expedite treatment decision-making while highlighting opportunities to optimize biomarker testing workflows.

Next-Generation Sequencing Completion and Timeliness Using a Reflex Testing Protocol for Patients with Stage II to IV Nonsquamous Non-Small Cell Lung Cancer.

BACKGROUND: Next-generation Sequencing (NGS) is critical for providing treatment recommendations across multiple stages of non-small cell lung cancer (NSCLC). However, a substantial proportion of patients do not undergo testing. This study evaluated the completion rates and timeliness of NGS in patients with stage II to IV NSCLC at a single academic institution with a reflex NGS testing protocol. METHODS: Patients with stage II to IV nonsquamous NSCLC (ns-NSCLC) diagnosed between 2015 and 2022 were identified retrospectively. A reflex, tissue-based testing protocol was initiated in 2015 using in-house NGS. Pyrosequencing was performed if NGS failed. RESULTS: 501 patients were included: 75 (15.0%) with stage II, 82 (16.4%) with stage III, and 344 (68.6%) with stage IV ns-NSCLC. Tissue NGS was completed in 380 (75.8%) patients and 465 (92.8%) completed some tissue-based genomic testing when including pyrosequencing. Median time from biopsy to NGS was 17.0 days (range, 6-61 days). 61.0% of patients had NGS results prior to a first treatment of any type and 88.4% had tissue NGS results prior to systemic therapy. Among stage IV patients with completed NGS, median overall survival was 2.27 years for patients with NGS results prior to first treatment compared to 1.08 years for patients without NGS results prior to treatment initiation (P = .04). CONCLUSIONS: Implementation of an in-house, reflex NGS testing protocol enabled rapid genomic profiling in a high proportion of patients with stage II to IV ns-NSCLC. NGS completion prior to receiving first-line therapy was associated with improved survival compared to completion after first line treatment in stage IV patients.

primary analysis of the RANDOMIZED eortc-2139/columbus-ad trial: Adjuvant encorafenib and binimetinib versus placebo in high-risk stage II BRAF-V600E/K melanoma.

PURPOSE: Stage IIB/IIC melanoma has a high risk of recurrence after resection. Combined BRAF/MEK inhibitor therapy showed benefit in resected high-risk stage III and advanced melanoma. The objective of this study was to investigate its role in stage IIB/IIC. METHODS: Adult patients with resected stage IIB/IIC cutaneous melanoma which had a BRAF V600E/K mutation were randomized 1:1 to receive encorafenib (enco) 450 mg QD + binimetinib (bini) 45 mg BID orally for one year or placebo. The study planned to randomize 815 patients and was designed to demonstrate superiority regarding recurrence-free survival (RFS). Following a premature termination of accrual, the study was amended with safety as the primary endpoint and RFS as secondary endpoint. RESULTS: Between June 9, 2022, and October 9, 2023, 339 patients were screened for a BRAF mutation and 110 randomized. Data cutoff was 19 Nov. 2024, after the last patient discontinued study participation. Among randomized patients, 87 (79%) had a BRAF V600E mutation, and 39 (35%) AJCC8 stage IIC. Median follow-up was 12 and 7 months for enco/bini and placebo arms, respectively. Among 54 patients who initiated enco + bini, grade ≥ 3 treatment-related adverse events (AE) occurred in 13 (24%) patients, and 18 (33%) patients had an AE leading to permanent treatment discontinuation. RFS at 12 months was 86% (95% CI: 65-95%) in the enco + bini and 70% (95% CI: 46-85%) in the placebo arm, distant metastasis-free survival at 12 months was 92% (95% CI: 77-97%) for enco + bini and 82% (95% CI: 55-93%) for placebo. CONCLUSION: EORTC 2139 - Columbus-AD demonstrated a consistent and manageable safety profile and encouraging efficacy results for the combination of enco and bini in resected stage IIB/C BRAF V600E/K-mutated cutaneous melanomas.

Effects of free-weight resistance training based on hexagonal barbell deadlift in older women: A 24-week randomized controlled trial.

PURPOSE: This randomized controlled trial examined effects of a 24-week hexagonal barbell deadlift (HBDL)-based free-weight resistance training program on body composition, trunk muscle function, and functional performance in older women. METHODS: Thirty-two women (67.6 ± 6.3 years) were randomly assigned to an HBDL group (DG, n = 16) or control group (CG, n = 16). DG trained twice weekly for 24 weeks under supervision. Primary outcomes were body composition and isokinetic trunk peak torque and average power at 60°/s and 120°/s. Secondary outcomes were isokinetic knee function, mobility, and maximal isotonic strength. Between-group differences after the intervention were examined by analysis of covariance (α = 0.05). RESULTS: After intervention, DG showed greater trunk lean mass (+0.4 kg vs. -0.2 kg, p = 0.006) than CG, and reductions in body fat percentage (-1.4% vs. +0.3%, p = 0.003), total fat mass (-1.1 kg vs. +0.3 kg, p = 0.013), and regional fat mass (trunk, gluteal, thigh; all p < 0.05). Trunk extensor peak torque at 60°/s (+26.0% vs. -6.3%, p < 0.001) and average power at 60°/s (+38.1% vs. -7.6%, p < 0.001) and 120°/s (+33.2% vs. +0.1%, p = 0.002) improved significantly. DG also showed better eyes-closed static balance and 6-min walk performance (both p < 0.05). Whole-body lean mass and lower-limb isokinetic strength did not differ between groups. Attendance was 89.6% with no adverse events. CONCLUSION: HBDL-based free-weight resistance training is a safe, feasible, and effective strategy to improve body composition, trunk extensor function, and mobility in older women.

Intervention Without Borders - an Automated Self-Guided AI-Enhanced Psychoeducation Intervention for Dementia Caregivers: Parallel-Group Randomized Waitlist-Controlled Trial.

OBJECTIVE: To examine whether a fully automated, self-guided intervention (PDC30) could improve caregiver well-being over a 1-month waitlist control in an international sample. DESIGN: Randomized waitlist-controlled trial. SETTING: Web-based platform accessible globally. PARTICIPANTS: 441 individuals responded to study promotion on the internet, of whom 274 from 43 countries met the study criteria and were randomized. Eligible participants were adults providing ≥10 care hours weekly to community-dwelling relatives with dementia, scoring ≥5 on Patient Health Questionnaire-9 (PHQ-9), and without recent caregiver intervention. INTERVENTION: Available 24/7, PDC30 is a self-guided, automated intervention consisting of a Guidebook, an AI-powered counseling chatbot, and interactive applications for cognitive-behavioral techniques, relaxation, and caregiver-recipient bonding. MEASUREMENTS: At baseline and follow-ups at 1, 2, and 3 months, depression was assessed by PHQ-9. Secondary outcomes were measured with validated brief versions of anxiety, burden, and positive gains. RESULTS: Intent-to-treat analysis using mixed-effects regression showed treatment x time2 effects on all outcomes except anxiety. At 1-month follow-up, coinciding with exclusive access to PDC30, intervention caregivers showed significant improvements in depression (d = -0.37), burden (d = -0.34), and positive gains (d = 0.42). The differences mostly disappeared after control participants received the intervention, while improvements in both groups were sustained thereafter. Participants reported using the website several times weekly, were generally satisfied with it, and found the chatbot most helpful. CONCLUSIONS: The effects on depression and other outcomes were consistent with those observed for in-person programs, suggesting the viability of well-designed automated intervention. The study demonstrates the feasibility, acceptability, and potential global health impact of PDC30.

Proteomic and metabolomic profiling reveals dysregulation of immune states, mucin-type glycosylation and steroid metabolism in extramammary Paget's disease.

BACKGROUND: Extramammary Paget's disease is a rare cutaneous adenocarcinoma characterized by mucin-rich Paget cells and chronic inflammation, yet its molecular basis remains unclear. OBJECTIVE: To systematically characterize the proteomic and metabolomic landscape of EMPD, uncover immune heterogeneity, and identify molecular pathways underlying tumor progression and microenvironment remodeling. METHODS: We performed integrated proteomic and metabolomic analyses on 92 male tumor patients and 30 healthy controls, identifying 10,217 proteins and 1466 metabolites. RESULTS: Extramammary Paget's disease lesions exhibited broad activation of inflammatory pathways. Immune profiling further uncovered substantial inflammatory heterogeneity, delineating immune-cold and immune-hot subtypes, with the latter associated with stronger invasive potential. Aberrant mucin-type glycosylation was also prominent, featuring Tn-modified MUC1 and MUC5AC accompanied by elevated GALNT7, GALNT6, GALNT4, and ST6GAL1, which correlated with inflammatory intensity. Metabolomic data demonstrated elevated levels of testosterone, dehydroepiandrosterone, and related intermediates in tumor tissues, indicating an androgen-enriched metabolic profile in extramammary Paget's disease. CONCLUSION: These findings reveal immune, glycoproteomic, and metabolomic pathways in extramammary Paget's disease pathogenesis and provide novel insights for molecular classification and therapeutic targeting.

Clinical characteristics and outcomes of post-stroke seizures following reperfusion therapy: a retrospective single-center study.

BACKGROUND: Post-stroke seizures (PSS) are a recognized complication of ischemic stroke and may adversely affect functional outcomes and survival; however, their characteristics in patients receiving contemporary reperfusion therapy remain incompletely defined. We aimed to describe the clinical characteristics, treatment patterns, and outcomes of patients who developed PSS following reperfusion therapy and to compare early- and late-onset seizure subgroups. METHODS: This single-center retrospective study included adult patients with acute ischemic stroke treated with intravenous thrombolysis (IV-tPA), mechanical thrombectomy (MT), or combined therapy between January 2020 and September 2025. Early seizures were defined as occurring within 7 days of stroke onset. Clinical, radiological, and treatment-related variables were analyzed, and functional outcome was assessed using the modified Rankin Scale at 3 months. RESULTS: Of 1242 patients who received reperfusion therapy, 53 (4.27 %; 95 % CI 3.28-5.54) developed PSS. Observed seizure rates were 3.39 % in the MT group, 4.06 % in the IV-tPA group, and 7.02 % in the combined therapy group; these observed rates did not differ significantly across treatment modalities. Early seizures occurred in 23 patients and late seizures in 30. No significant differences were found between early- and late-onset seizure subgroups in demographic characteristics, vascular risk factors, stroke severity, reperfusion success, or clinical outcomes, with the exception of an isolated, exploratory difference in stroke laterality. Three-month mortality among patients with PSS was 45.28 % (95 % CI 32.66-58.55), and in-hospital mortality was 20.75 %. CONCLUSIONS: In this single-center cohort, the incidence of PSS after reperfusion therapy was comparable to previously reported rates, with no marked differences across treatment modalities. The high mortality among patients with PSS likely reflects underlying stroke severity rather than a treatment-specific risk.

Association of time-averaged systemic immune-inflammation indices with in-hospital mortality after intracerebral hemorrhage: a retrospective study.

BACKGROUND: Systemic inflammation plays a central role in secondary brain injury following intracerebral hemorrhage (ICH). Although inflammatory indices such as the neutrophil-to-lymphocyte ratio (NLR), systemic immune-inflammation index (SII), and systemic inflammation response index (SIRI) are linked to poor outcomes, their associations with mortality are commonly assumed to be linear, potentially overlooking nonlinear patterns where mortality risk rises steeply at higher levels. METHODS: We conducted a retrospective study using the MIMIC-IV database, including 440 patients with non-traumatic ICH who were alive and remained in the ICU for at least 72 h after admission. Mean NLR, SII, and SIRI were calculated from measurements obtained during this period. Multivariable logistic regression and restricted cubic spline (RCS) analyses were applied to assess their independent and nonlinear associations with in-hospital mortality. Model discrimination and calibration were internally validated using 1,000 bootstrap resamples. RESULTS: The in-hospital mortality rate was 26.1%. After multivariable adjustment, NLR and SIRI remained independently associated with mortality. Patients in the highest SIRI quartile had the highest risk of death (aOR = 5.12; 95% CI: 2.57-12.24; p < 0.001). RCS analysis revealed a significant nonlinear association between SIRI and mortality (p-nonlinearity < 0.05), showing a steep risk increase at higher SIRI levels. Adding SIRI to the base model provided a modest improvement in discrimination (AUC 0.762 to 0.785, p = 0.045) and significantly improved risk reclassification (cNRI = 0.4778, p < 0.001; IDI = 0.0240, p = 0.0151). CONCLUSIONS: Among patients with ICH who met the 72-hour eligibility criterion, higher 72-hour average SIRI was independently associated with in-hospital mortality. As a time-averaged measure, SIRI should be interpreted as a dynamic marker integrating the initial inflammatory state and the early clinical course rather than as a purely baseline prognostic factor. Although adding SIRI to the base model modestly improved discrimination and risk reclassification, it should be considered a candidate prognostic marker requiring external validation before clinical application.

Vestibular schwannoma associated normal pressure hydrocephalus: clinical features and shunt responsiveness compared with idiopathic NPH.

BACKGROUND: Vestibular schwannoma (VS) is commonly associated with obstructive hydrocephalus due to mass effect; however, a rarer communicating form resembling normal pressure hydrocephalus (NPH) has also been described, possibly related to impaired CSF absorption from elevated CSF protein. We aimed to characterize the clinical and imaging features of VS-associated NPH (VS-NPH) and compare them with those of an idiopathic NPH (iNPH) cohort. METHODS: We retrospectively analyzed 18 patients with VS-NPH identified between 2008 and 2024. For comparison, 41 iNPH patients were drawn from a prospective longitudinal study at our center. Variables included demographics, tumor size, VS treatment modality, CSF parameters, Radscale imaging features, and shunt responsiveness. RESULTS: VS-NPH patients had markedly higher CSF protein levels than patients with iNPH (median 100 vs. 51 mg/dL, p < 0.001). Radiological features largely overlapped; however, parasagittal sulcal narrowing was more frequent in VS-NPH (61 % vs.13 %, p = 0.002). These differences remained significant in the sensitivity analysis excluding the two patients without gait impairment. VS-NPH patients were younger in the primary analysis (66.8 vs. 72.0 years, p = 0.03), while exploratory associations between larger tumor size and both earlier NPH symptom onset (r = -0.48, p = 0.049) and smaller callosal angle (r = -0.49, p = 0.048) attenuated to non-significant trends in the sensitivity analysis. Tumor size was < 30 mm in 89 % of patients. Ventriculoperitoneal shunt (VPS) resulted in clinical improvement in both groups, although response rates were numerically lower in VS-NPH than in iNPH (63 % vs.75 %). CTT was positive in 9 of 11 VS-NPH patients who underwent testing, although improvement after shunting also occurred in patients with negative CTT results or without prior CTT. CONCLUSIONS: VS-NPH may represent a secondary subtype of NPH with distinct biochemical and subtle imaging features. Elevated CSF protein may contribute to altered CSF dynamics. These findings are exploratory and require confirmation in larger prospective studies.

Patient-reported outcomes with tarlatamab in extensive-stage small cell lung cancer after platinum-based chemotherapy: results from the phase 3 DeLLphi-304 trial.

BACKGROUND: Extensive-stage small cell lung cancer (ES-SCLC) is associated with a high symptom burden and impaired health-related quality of life (HRQoL). This prespecified analysis from the phase 3 DeLLphi-304 trial evaluated patient-reported outcomes (PROs) for tarlatamab versus standard-of-care (SoC) chemotherapy following first-line platinum-based therapy. METHODS: DeLLphi-304 is a multicenter, open-label, randomized phase 3 study in adults with ES-SCLC. PROs were assessed using validated instruments, including the EORTC QLQ-C30, EORTC QLQ-LC13, FACT-G GP5, BPI-SF, and the EQ-5D-5L visual analogue scale. Change from baseline, response rates, and time to deterioration in these PROs were analyzed. RESULTS: PRO data from all 509 patients enrolled were evaluated. Compliance with QLQ-C30 and QLQ-LC13 assessments remained above 69% through 19 weeks. A higher proportion of patients receiving tarlatamab achieved symptom or functional improvement at 19 weeks compared with SoC in chest pain (19% vs 10%), cough (35% vs 26%), dyspnea (22% vs 7%), physical functioning (13% vs 8%), and global health status (23% vs 15%), respectively. Tarlatamab also delayed deterioration in symptoms, physical functioning, and pain at worst relative to SoC. FACT-G GP5 results indicated that patients receiving tarlatamab were less bothered by treatment side effects over time. CONCLUSIONS: In addition to its previously reported antitumor activity, tarlatamab demonstrated clinically meaningful improvements in symptoms and HRQoL compared with SoC. These findings support a favorable benefit-risk profile of tarlatamab in patients previously treated for ES-SCLC.

Optical Genome Mapping Is a Powerful Diagnostic Tool in Non-Hodgkin Lymphoma.

Non-Hodgkin lymphoma (NHL) is a diverse and heterogeneous group of hematological malignancies. These lymphomas arise from the clonal proliferation of either B/T or natural killer lymphocytes, and their correct classification relies partly on identifying characteristic structural variants and copy number alterations. Current standard-of-care technologies for detecting these genomic features, chromosome banding analysis (CBA) and fluorescent in situ hybridization (FISH), are labor intensive and have specific limitations. CBA has low resolution and relies on viable cell culture, whereas the targeted approach of FISH does not provide the whole genome view required for comprehensive disease characterization. This highlights the need for higher-resolution nontargeted genomic methods. Previous studies have evaluated optical genome mapping (OGM) as a whole genome alternative for cytogenomic characterization in NHL diagnostics but were restricted in number and to cases with peripheral blood and/or bone marrow invasion. Here, we selected a comprehensive cohort of 110 NHL cases (79 B-NHL and 31 T-NHL/natural killer-NHL) derived from different types of tissue biopsies, all with established histopathological diagnoses. Seventy-eight samples were genomically well characterized at diagnosis by CBA and FISH. The remaining 32 cases were included because of previous CBA failure, although FISH data were available for 20 cases. OGM provided informative results in 94% of the cohort, with a high concordance rate of 97.6% compared with CBA/FISH in detecting clinically relevant aberrations. The 2 variants that were missed were both present at the detection threshold of OGM. In contrast, OGM successfully resolved 26 samples with previous CBA failure and detected 3 additional disease-defining events, resulting in diagnostic reclassification of 1 patient. Finally, OGM identified novel recurrent aberrations that warrant further investigation into their pathogenetic implications. To conclude, OGM robustly detects clinically relevant structural variants and copy number alterations and presents a promising alternative to CBA and FISH in routine diagnostic evaluation of NHL.

Estrogen Receptor, GATA-3, TTF-1, and KRAS in Endometrial Carcinoma of No Specific Molecular Profile: Prognostic or Diagnostic Markers?

Endometrial carcinoma with no specific molecular profile (NSMP) is a clinicopathologically heterogeneous group of diseases with an overall intermediate prognosis. Prognostic refinement is needed for better personalized treatment. The updated European Society of Gynecological Oncology-European Society for Radiotherapy and Oncology-European Society of Pathology guidelines for endometrial carcinoma stratify NSMP according to histotype and estrogen receptor (ER) status. ER (with other ancillary markers) also helps differentiate histotypes of endometrial carcinoma. This study describes clinicopathological characteristics of ER-positive and -negative-NSMP endometrial carcinoma. Furthermore, we investigate the prognostic and diagnostic significance of ER, GATA3, TTF1, and KRAS in a large and relatively unselected NSMP carcinoma cohort. POLE sequencing results and immunohistochemistry for p53, mismatch repair proteins, and ER were available for 930 samples of endometrial carcinoma. Within NSMP cases (n = 377), 22 samples presented ER staining in <1% of the carcinoma cells, 5 cases in 1% to 9%, and 350 cases in ≥10%. ER expression ≥10% predicted an excellent outcome (comparable with POLE-mutated cases) in univariable analysis, where ER negativity (<10%) was associated with a poor outcome (comparable with p53 abnormal cases). Most ER-positive NSMP cases were low-grade endometrioid carcinomas, whereas most ER-negative NSMP cases were nonendometrioid or high-grade endometrioid carcinomas. In addition to high-risk histotype, ER negativity was associated with various other clinicopathological risk factors. In multivariable analysis adjusting for histotype and other risk factors, ER did not independently predict disease progression (P = .814). No disease-related deaths were observed in the rare (n = 3) patients with ER-negative-low-grade endometrioid carcinoma. GATA3/TTF1 positivity and KRAS mutation were discovered not only in mesonephric-like carcinoma but also in endometrioid carcinoma. No prognostic relevance was found for these markers. In conclusion, the different prognosis of ER-positive vs ER-negative-NSMP endometrial carcinoma is not attributable to ER status itself but rather to its strong correlation with histotype and other clinicopathological risk factors. Limited specificity of GATA3, TTF1, and KRAS warrants caution in their use as diagnostic markers of mesonephric-like carcinoma.

Loss of Methylthioadenosine Phosphorylase (MTAP) Expression: A Potentially Useful Tool for Distinguishing Sarcomatoid Urothelial Carcinoma From Inflammatory Myofibroblastic Tumor.

Inflammatory myofibroblastic tumor (IMT) and sarcomatoid urothelial carcinoma (SarUC) can have striking histologic overlap but have significantly different prognoses and clinical management paradigms. Loss of methylthioadenosine phosphorylase (MTAP) protein expression by immunohistochemistry (IHC) serves as a useful surrogate for homozygous 9p21 deletion, a recurrent genomic alteration in urothelial carcinoma (UC). We analyzed MTAP expression by IHC in 65 SarUCs and 27 urinary tract IMTs to evaluate its utility in navigating this challenging differential diagnosis. Overall, MTAP loss was significantly more frequent in SarUC (55%) compared with IMT (4%) (P < .0001). Among 46 biphasic SarUCs with independently evaluable epithelial and mesenchymal components, divergent expression patterns were frequent. The most common pattern was retention of MTAP staining in both epithelial and mesenchymal components (19/46; 41% of cases), followed by selective retention of MTAP in the epithelial component and loss in the mesenchymal component (16/46; 35% of cases). MTAP loss was observed in both the epithelial and mesenchymal components in 11 out of 46 (24%) SarUC cases. None of the 46 biphasic SarUC cases showed selective MTAP loss in the epithelial component but retention in the mesenchymal component. MTAP IHC was also particularly valuable in assessing clonal relationships in 2 challenging biphasic cases in which the differential diagnosis included a collision between a noninvasive low-grade papillary UC and an IMT versus a subtle IMT-like SarUC arising in association with an overlying noninvasive low-grade papillary UC. Next-generation sequencing on a subset of cases (n = 11) was useful for confirming 9p deletion in cases with MTAP loss by IHC, and for demonstrating molecular hallmarks of urothelial neoplasia thereby providing additional diagnostic support for morphologically challenging SarUC cases with IMT-like morphology. Therefore, MTAP IHC can be useful in evaluating spindle cell lesions of the urinary tract, as loss is significantly more common in SarUC than in IMT, and enriched in the mesenchymal component of biphasic SarUC. However, MTAP loss can be seen in both entities, and the diagnosis of IMT-like spindle cell tumors in the urinary tract requires careful integration of morphologic, immunohistochemical, and molecular data.

Clinical Utility of Next-Generation Sequencing in Tumors Diagnosed as Lung Squamous Cell Carcinoma: Real-World Data of Diagnostic and Therapeutic Implications.

Lung squamous cell carcinoma (LUSC) is the second most common subtype of non-small cell lung carcinoma (NSCLC), typically associated with a poor prognosis. Unlike lung adenocarcinoma, the application of next-generation sequencing (NGS) in LUSC has lagged because of the long-standing perception of low therapeutic yield, primarily based on highly selected, resected cohorts. We sought to determine the real-world clinical utility of NGS in LUSC. We analyzed an institutional cohort of 576 tumors initially diagnosed as LUSC that underwent NGS profiling. We defined "clinical yield" as either diagnostic reclassification or the identification of a targetable mitogenic alteration. Twenty cases (3.5%) were reclassified, including rediagnosis to cutaneous squamous cell carcinoma, transformed adenocarcinoma (post targeted therapy), and rare entities such as nuclear protein of the testis-rearranged carcinoma and lymphoepithelial carcinoma. Primary mitogenic drivers were identified in 83 cases (14.4% of the total cohort), of which 43 (7.5% of the total cohort) harbored alterations with currently Food and Drug Administration-approved therapies for NSCLC (including KRAS, EGFR, MET, ALK, and ROS1). Overall clinical yield-defined as the sum of diagnostic reclassifications and identification of NSCLC-specific targetable alterations-was 11.0% (63/576). Univariate and multivariate analysis demonstrated that never or light smoking history was the strongest independent predictor of clinical yield, with 57.3% of tumors in this subset being reclassified or harboring a strong driver. Our findings demonstrate that NGS provides significant diagnostic and therapeutic value in a real-world LUSC cohort, challenging the historical premise of low yield. Although clinicodemographic features can help prioritize testing in resource-limited settings, the identification of targetable drivers across all smoking groups supports the universal application of comprehensive NGS for all patients diagnosed with LUSC.
