BACKGROUND Schwannomas, also known as neurilemmomas, are benign slow-growing neoplasms originating from a Schwann cell sheath. These neoplasms are rare among the mesenchymal tumors of the gastrointestinal tract. In the stomach, Schwannomas only represent 0.2 % of all gastric tumors; this makes the presentation of a schwannoma in the stomach of a man in his seventh decade unusual. This case repo...

N-Nitrosocimetidine, a nitroso derivative of the drug cimetidine, was given to groups of 20 male and 20 female rats in drinking water at a concentration of 0.5 mM for more than 2 years. The life span of the rats was not decreased compared with untreated control animals, and there was no significant increase in incidence of any tumor that could be attributed to the treatment. In comparison, 45% ...

Gastric stromal tumors are rare neoplasms of the stomach. In this report we present a gastric stromal tumor with an exophytic growth pattern, and describe magnetic resonance imaging and endoscopic ultrasonography findings.

Carcinosarcoma of the esophagus and the stomach are rare neoplasms characterized by the simultaneous presence of carcinomatous and sarcomatous elements. There is no report in the literature of carcinosarcoma of the esophagogastric junction. We present a case of carcinosarcoma of the esophagogastric junction whose unique clinical presentation, surgical issues, morphological and immunohistochemic...

objective(s): accumulating evidence has demonstrated that mirnas contribute to various genetic and epigenetic modifications in the pathogenesis of gastric cancer (gc). recent studies focused on the four single nucleotide polymorphisms (snps) of pre-mirnas including rs11614913, rs3746444, rs2910164, and rs2292832. it was suggested that these four snps were significantly associated with the risk ...

Metastatic tumors of the stomach are rare. Although neoplasms from almost every tissue have been reported to metastasize to the stomach, lung cancer is a rare cause. We report the case of 46-years-old man presented with superior Vena Cava syndrome. Histopathological diagnosis was non-small cell lung cancer with computed tomography-guided needle biopsy of lung. Since gastric symptoms occurred du...

Schwannomas, also known as neurinomas or neurilemmomas, are generally benign, slow-growing neoplasms originating in any nerve that has a Schwann cell sheath. These neoplasms are rare among the spindle cell mesenchymal tumors of the gastrointestinal tract, but develop most commonly in the stomach representing 0.2% of all gastric tumors. We present the case of a 57-year-old female patient with a ...

Objective(s): Cucurbitacins exhibit a range of anti-cancer functions. We investigated the effects of cucurbitacins D, E, and I purified from Ecballium elaterium (L.) A. Rich fruits on some apoptotic and autophagy genes in human gastric cancer cell line AGS. Materials and Methods: Using quantitative reverse transcription PCR (qRT-PCR), the expression of LC3, VEGF, BAX, caspase-3, and c-MYC genes...

As well as highlighting the experience using self-expanding stents on basis endoscopic department Omsk Clinical Oncological Dispensary. Stenting with self-healing plastic for malignant neoplasms esophagus, cardiac stomach refers modern minimally invasive method...
