Gastric Intestinal Metaplasia in Children and Adolescents Is Reversible upon Reaching Adulthood-Results from a Long-Term Cohort Study.

Background/objectives: Gastric intestinal metaplasia (GIM) is considered an irreversible preneoplastic precursor for gastric adenocarcinoma in adults. However, its significance in children and the long-term outcome remain poorly understood.

Methods: All children diagnosed with GIM between 2000 and 2020 were identified at a large tertiary referral centre.

Upregulation of Differentiates Intrahepatic Cholangiocarcinoma from Hepatocellular Carcinoma and Both Colorectal and Pancreatic Adenocarcinoma Liver Metastases.

Background: Altered gene expression in cancers holds great potential to improve the diagnostics and differentiation of primary and metastatic liver cancers. In this study, the expression of the protein-coding genes ring finger protein 135 (), ephrin-B2 (), ring finger protein 125 (), homeobox-C 4 (), actin-binding LIM protein 1 () and oncostatin M receptor () and the long non-coding RNAs (lncRNA) prospero homeobox 1 antisense RNA 1 () and leukemia inhibitory factor receptor antisense RNA 1 () was investigated in hepatocellular carcinoma, cholangiocarcinoma, colorectal liver metastases and pancreatic ductal adenocarcinoma liver metastases.

Methods: This study included 149 formalin-fixed, paraffin-embedded samples from 80 patients.

Aggressive Subtypes of Laryngeal Chondrosarcoma and their Clinical Behavior: A Systematic Review.

Introduction: Laryngeal chondrosarcoma (CS) is a rare indolent malignant tumor. High-grade (G3), dedifferentiated (DD), and myxoid (MY) CSs are considered more aggressive subtypes due to their metastatic potential and relatively poor outcomes. The aim of this systematic review is to evaluate treatment modalities and survival outcomes in patients affected by these rarer CS subtypes.

DNA Methylation Panels for the Differentiation of Lung and Gastric Adenocarcinomas from Other Common Primary Adenocarcinomas.

: Gastric and lung adenocarcinomas are among the most common adenocarcinomas worldwide. Our research aimed to validate methylation biomarkers that differentiate gastric and lung adenocarcinomas from hepatocellular carcinoma, cholangiocarcinoma, colorectal carcinoma, pancreatic adenocarcinoma and paired healthy tissues. : The study analyzed 178 formalin-fixed, paraffin-embedded tissue samples, including 14 gastric adenocarcinomas, 15 lung adenocarcinomas, 15 hepatocellular carcinomas, 15 cholangiocarcinomas, 15 colorectal carcinomas, 15 pancreatic adenocarcinomas and their paired healthy tissues.
