In this case-enriched cohort, the capsule-sponge was safe and feasible, and cytology with adjunct p53-IHC showed high accuracy for ESN/early ESCC. Validation in asymptomatic high-risk cohorts is warranted to define real-world performance and triage utility (NCT04192695).
This case report presents a highly unusual case of a primary high-grade malignant peripheral nerve sheath tumor (MPNST) of esophagus, a neoplasm of extreme rarity, with fewer than twenty histologically confirmed cases reported worldwide to date; detailing the successful management of this tumor through Orringer's transhiatal esophagectomy, complemented by comprehensive histopathologic and immunohistochemical evaluation. Our report emphasizes the crucial the role of immunohistochemistry, specifically the diagnostic value of S100, SOX10, and the exclusion of gastrointestinal stromal tumors markers (DOG1, CD117) in distinguishing MPNST, from morphologically similar esophageal submucosal tumors.
A prognostic nomogram integrating miR-15b-5p, BTG2 and clinical parameters demonstrated robust predictive accuracy (C-index: 0.78). The miR-15b-5p/BTG2 axis represents a novel regulatory mechanism in ESCA progression with significant potential as both a prognostic biomarker and therapeutic target.
