Gastrointestinal epithelial neoplasia: Vienna revisited

The Vienna classification of gastrointestinal epithelial neoplasia.

BACKGROUND Use of the conventional Western and Japanese classification systems of gastrointestinal epithelial neoplasia results in large differences among pathologists in the diagnosis of oesophageal, gastric, and colorectal neoplastic lesions. AIM To develop common worldwide terminology for gastrointestinal epithelial neoplasia. METHODS Thirty one pathologists from 12 countries reviewed 35...

Combination of Paris and Vienna Classifications may Optimize Follow-Up of Gastric Epithelial Neoplasia Patients

BACKGROUND The aim of this study was to evaluate the efficiency of the combination of Paris and Vienna classifications in a follow-up study of gastric epithelial neoplasia (GEN) patients. MATERIAL AND METHODS This study was conducted between January 2003 and September 2010, during which 170 biopsy-proven GEN patients were followed up by gastroenterologists and pathologists according to our fo...

Determination of matrilysin activity in gastrointestinal neoplasia.

[Pathologic diagnosis of gastric epithelial neoplasia].

Gastric epithelial neoplasia is a very common disease entity in Korea, encompassing gastric adenoma and adenocarcinoma. There are still discrepancies in pathologic diagnosis of gastric epithelial neoplasia between Western and Japanese pathologists after Vienna consensus classification. With increasing use of endoscopic therapy such as endoscopic mucosal resection and endoscopic submucosal disse...

Stromal-epithelial interactions in early neoplasia.

In prostate tumors, both the epithelial and stromal mesenchyme compartments show gene expression changes from their respective normal counterpart. In fact, there are more such changes in the stroma than the epithelium. These include down-regulated expression of genes involved in smooth muscle cell differentiation and those differentially expressed between prostate and bladder, i.e., organ-restr...
