Gastric Xanthelasma, Microsatellite Instability and Methylation of Tumor Suppressor Genes in the Gastric Mucosa: Correlation and Comparison as a Predictive Marker for the Development of Synchronous/Metachronous Gastric Cancer.

A predictive marker for the development of synchronous/metachronous gastric cancer (GC) would be highly desirable in order to establish an effective strategy for endoscopic surveillance. Herein, we examine the significance of gastric xanthelasma (GX) and molecular abnormalities for the prediction of synchronous/metachronous GC. Patients ( = 115) were followed up (range, 12-122; median, 55 months) in whom the presence of GX and molecular alterations, including microsatellite instability (MSI) and methylation of (), () and () genes, had been confirmed in non-neoplastic gastric mucosa when undergoing endoscopic submucosal dissection (ESD) for early GC.

Radiology report language positively influences adrenal incidentaloma guideline adherence.

Background: Adrenal incidentalomas are common radiographic findings. Guidelines recommend biochemical and radiographic surveillance of adrenal incidentalomas. We investigated if patients were appropriately referred for outpatient evaluation.
