MET Expression in Upper Gastrointestinal Adenocarcinoma: Prevalence, Prognostic Impact, and Implications for Anti‐MET Antibody‐Drug Conjugate Therapy

International Journal of Cancer, EarlyView.
ABSTRACT MET is an actionable receptor tyrosine kinase, and MET‐directed antibody–drug conjugates (ADCs) have recently entered clinical practice with FDA approval in non‐small cell lung cancer and are now being evaluated across gastrointestinal malignancies, with patient selection based on MET immunohistochemistry (IHC) 3+ membranous staining at ...

Prevalence of intestinal metaplasia, dysplasia, and esophageal adenocarcinoma in patients with irregular Z-line: a systematic review and meta-analysis [PDF]

Clinical Endoscopy
Background/Aims The irregular Z-line, defined as a segment of columnar mucosa less than 1 cm in the distal esophagus, is often biopsied despite guidelines advising against it due to a low risk of progression to esophageal adenocarcinoma (EAC).

Sex‐Specific Proteomic Profiling Identifies Pregnancy Zone Protein as a Complement‐Linked Marker of Adverse Prognosis in Esophageal Adenocarcinoma

International Journal of Cancer, EarlyView.
ABSTRACT Esophageal adenocarcinoma (EAC) exhibits marked male predominance with male‐to‐female ratios reaching 8.5:1, yet the molecular basis underlying this sex disparity remains poorly characterized. We analyzed 92 EAC specimens using mass spectrometry–based proteomics, comprising 47 female and 45 male tumors from treatment‐naïve patients ...

Use of single‐use ultra‐slim endoscopes for evaluation of pediatric esophageal varices: A pilot feasibility study

JPGN Reports, EarlyView.
ABSTRACT Esophageal varices (EV) need monitoring in patients with portal hypertension. In 2022, a single‐use ultra‐slim (3.5 mm) gastroscope was approved for use in children and adults. This study evaluated if an ultra‐slim gastroscope could evaluate, grade, and corroborate the presence of EV in sedated pediatric patients as compared to standard oral ...
