In the current study, we investigated the chemopreventive activity of arabinoxylan rice bran, MGN-3/Biobran, against chemical induction of glandular stomach carcinogenesis in rats. Gastric cancer was induced by carcinogen methylnitronitrosoguanidine (MNNG), and rats received MNNG alone or MNNG plus Biobran (40 mg/kg body weight) for a total of 8 months. Averaged results from 2 separate readings...

BACKGROUND Gastric and esophageal cancers are among the most lethal human malignancies worldwide. Of all malignancies estimated in Iran (47,100), gastric and esophageal cancers were responsible for 7,800 and 3,500 deaths in 2008 respectively. The present study aimed to provide an image of patho-epidemiological characteristics with their trends during two past decades with emphasis on topographi...

Genetic damages are frequently found in both tumor and normal cells at carcinogen exposed areas in the patients with upper aerodigestive tract cancer. These phenomena are explained by the multistage process and/or field cancerization theories. The c-erbB-2 proto-oncogene has been amplified in many human tumors including breast, stomach, kidney and lung cancers. To study the possible evidence of...

We report a rare case of the coexistence of a gastric small cell neuroendocrine carcinoma with a gastric adenocarcinoma. A 62-year-old man presented with epigastric soreness for 1 month. Esophagogastroduodenoscopy revealed a Borrmann type I tumor at the lesser curvature of the lower body of the stomach. The patient underwent a distal gastrectomy with D2 lymph node dissection and the resected sp...

Despite substantial declines in gastric cancer incidence, the incidence of adenocarcinoma esophagogastricjunction (AEG) has been rising remarkably worldwide and is drawing considerable attention as well concern.However, optimal extent esophagogastric resection for this tumor entity, especially Siewert type II tumorslocated at true cardia, remains highly controversial. Given uncertainty about pr...
