Gastric inverted hyperplastic polyp (IHP) is a rare gastric characterized by the downward growth of mucosal components into submucosal layer.Macroscopically, IHP resembles subepithelial tumor (SET); as result, accurately diagnosing difficult.This issue has clinical significance because can be misdiagnosed SET or malignant neoplasm In addition, adenocarcinoma accompany benign IHP.Although in most cases, IHPs are asymptomatic and found incidentally, these polyps may cause anemia secondary to...
Gastrointestinal stromal tumors (GISTs) frequently harbor activating gene mutations in either KIT or platelet-derived growth factor receptor A (PDGFRA) and are highly responsive to several selective tyrosine kinase inhibitors. In this study, a targeted next-generation sequencing (NGS) assay with an Oncomine Focus Assay (OFA) panel was used for the genetic characterization of molecular targets 30 Korean patients GIST.Using OFA that enables rapid simultaneous detection hotspots, single...
Background: Liquid-based cytology is currently known as an effective method, and cervical has been shown to be especially from of malignancy detection. In our study, the cytological detection rates Thinprep (Liquid-based cytology) conventional (bronchial washing & brushing) for endobronchial lesions were compared. Methods: Between July 2005 September 2005, data 30 patients with respiration symptom, who had abnormal lesion on bronchoscopy, collected. Results: The bronchoscopic biopsy group...
Background and Objectives: This study aimed to objectively determine microsatellite instability (MSI) status using a next-generation sequencing (NGS)-based MSI panel resolve the discrepancy regarding whether or not is rare phenomenon, irrespective of diverse genomic alterations in gastrointestinal stromal tumors (GISTs). Materials Methods: Genomic DNA was subjected an Ion AmpliSeq Microsatellite Instability Assay, as well cancer gene Oncomine Focus Assay. Results: All our GIST patients...
Purpose: To evaluate the usefulness of US and mammography in detecting extensive intraductal component (EIC) invasive cancer correlating results with histopathologic grade. Materials Methods: We retrospectively reviewed mammographic sonographic features 125 breast cancers, classified as EIC (n=57) without (n=68). The are microcalcifications only, beyond soft tissue density, density microcalcification, according to ten suspicious for malignancy by Stavros. calculated sensitivities,...
Background: We aimed to investigate molecular factors potentially related the progression of gastric adenoma (GA) cancer (GC) and compare mutation characteristics between GC GA. Methods: conducted custom gene panel sequencing for 135 GC-related genes estimated difference in somatic profiles 20 GA cases. Results: A total 31 mutations, including 22 missense, 3 nonsense, 6 frameshift were detected 17 samples. an average 1.8 mutations per sample (range, 1 mutations), with 12 5 tended have one or...
