These data support the need for systematic intraoperative nodal evaluation to confirm pathologic stage and inform treatment selection.</div></div><div><h3>Conclusions</h3><div>Although EBUS-TBNA is the preferred initial staging modality due to its minimally invasive nature, its diagnostic limitations warrant a low threshold for additional nodal evaluation. Systematic intraoperative lymph node evaluation at the time of surgical resection is indispensable for definitive staging, providing clinically actionable data that influences treatment decisions. Optimal staging of non–small cell lung cancer requires a multidisciplinary, individualized approach that combines modalities based on pretest probability, imaging findings, and patient factors.</div></div>","PeriodicalId":74032,"journal":{"name":"JTCVS open","volume":"30 ","pages":"Article 101685"},"PeriodicalIF":1.9,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147720862","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recently, the ESOPEC multicenter phase III trial reported superior overall survival (OS) with perioperative FLOT (5-FU/leucovorin/oxaliplatin/docetaxel) compared to CROSS. We aimed to examine trends in neoadjuvant treatment strategies and compare outcomes in a contemporary real-world cohort.</div></div><div><h3>Methods</h3><div>Patients with clinical stage II-IVA (T2-4aN0-3M0 by the American Joint Committee on Cancer 8th Edition staging classification) EAC who underwent neoadjuvant chemoradiation (nCRT; ≥41.4 Gy) or neoadjuvant chemotherapy (nCT) followed by esophagectomy were identified in the National Cancer Database (2015-2022). Postoperative outcomes and overall survival (Kaplan-Meier) were compared in propensity-matched cohorts.</div></div><div><h3>Results</h3><div>A total of 9845 patients were identified, of whom 8955 (91.0%) received nCRT and 890 (9.0%) received nCT before esophagectomy. The median patient age was 65 years (interquartile range [IQR], 58-71 years), and 88.1% (n = 8674) of the patients were male. Over time, there was trend toward increasing use of nCT, from 6.7% of patients in 2015 to 9.6% in 2022 (<em>P</em> < .001). In well-balanced matched cohorts (1:1, nCT vs nCRT; n = 106), despite an improved pathologic response with nCRT, nCT was associated with improved OS (median, 51.4 months vs 40.5 months; <em>P</em> = .029; hazard ratio, 0.82; 95% confidence interval, 0.68-0.98) and a better 5-year OS rate (49.8% vs 43.3%) at a median follow-up of 28.8 months (IQR, 17.2-42.5 months).</div></div><div><h3>Conclusions</h3><div>In a contemporary cohort of patients with locally advanced EAC, nCRT remained the predominant approach.
