Gastric carcinoma: A multicentric lesion

HER2 status in advanced gastric carcinoma: A retrospective multicentric analysis from Sicily

According to the ToGA trial, HER2 has been shown to be predictive for the success of treatment with trastuzumab in advanced gastric cancer (AGC). A number of studies have analyzed HER-2/neu overexpression in gastric carcinoma and identified the rate of HER2 positivity to be markedly varied. To date, the prevalence of HER2 overexpression in Sicilian people with AGC is unknown. Therefore, in the ...

Multicentric Type 3 Gastric Neuroendocrine Tumors

A 50-year-old woman with incidentally detected multiple gastric polyps and biopsy-proven neuroendocrine tumor (NET) was referred to our hospital. More than 10 polypoid lesions (less than 15 mm) with normal gastric mucosa were detected from the gastric body to the fundus. The serum level of gastrin was within the normal limits. There was no evidence of atrophic changes on endoscopy and serologic...

A dangerous gastric bleeding cause: Dieulafoy's lesion

Bleeding is a complication of gastrointestinal vascular malformation and may be an emergency. Dieulafoy's lesion is rare but the aberrant submucosal artery may cause gastrointestinal bleeding. It is most commonly located in the proximal part of the stomach. Endoscopy is used for diagnosis and treatment. Mass lesions, diffuse lesions and severe bleeding may require surgery. Wedge resection or le...

Patient with a gastric subepithelial lesion

......................................... Received: 05-10-10 Accepted: 25-11-10 Abstract Although subepithelial lesions are rarely found in the upper gastrointestinal tract, they can cause uncertainty in diagnostic approach and management. Endosonographic findings are described and current recommendations are reviewed in light of one case in order to allow for a rational approach to these lesions.
