The gastric cancer generally is considered a geriatric disease, which occurs commonly among lower socioeconomical levels of the populations. There are wide differences in the gastric cancer occurrence among different geographical regions. In Iran, the northern and the northwestern regions are with the most higher risk of gastric cancer occurrences. In spite of the recent gastroscopical examinat...

UNLABELLED Recently, the presence of microsatellite instability (MSI) has been reported in gastric cancer and associated with older age of presentation, distal tumor location, early disease staging, and better overall prognosis. Different characteristics in presentation and in tumor behavior may be explained by different genetic alterations during carcinogenesis of gastric cancer. Identificatio...

An accurate staging is necessary to select the best treatment and evaluate prognosis in oncology. Staging usually begins with noninvasive imaging such as computed tomography, magnetic resonance imaging or positron emission tomography. In the absence of distant metastases, endoscopic ultrasound plays an important role in the diagnosis and staging of gastrointestinal tumors, being the most accura...

Chronic gastritis is an inflammatory condition of the gastric mucosa that may include structural alterations of the glandular compartment. The semiquantitative scoring systems advocated in the Sydney Systems and the subsequent Atrophy Club Guidelines remain essential for the recognition of the spectrum of the lesions detectable in gastric inflammatory disease. Most practicing pathologists, howe...

OBJECTIVE FDG-PET can contribute significantly to the preoperative period of patients with planned curative resections or with isolated liver or lung metastasis. In this study, we analyze the importance and diagnostic value of FDG-PET in the preoperative evaluation of gastric cancers by correlating its value with computerized tomography (CT). MATERIALS AND METHODS A prospective study was cond...

BACKGROUND Endoscopic ultrasound (EUS) may be used for preoperative staging of gastro-oesophageal carcinoma but performance values given in the literature differ. AIMS To identify and synthesise findings from all articles on the performance of EUS in tumour, node, metastasis (TNM) staging of gastro-oesophageal carcinoma. SOURCE Published and unpublished English language literature, 1981-199...

BACKGROUND In this study, we established a hypothetical tumor-lodds-metastasis (TLM) and tumor-ratio-metastasis (TRM) staging system. Moreover, we compared them with the 7(th) edition of American Joint Committee on Cancer tumor-nodes-metastasis (AJCC TNM) staging system in gastric cancer patients after D2 resection. METHODS A total of 1000 gastric carcinoma patients receiving treatment in our...

Purpose of the study. To find out abilities multispiral computed tomography (MSCT) using intravenous bolus injection in detecting and preoperative esophago-gastric junction cancer staging order to improve diagnosis this pathological condition. Materials methods . The patients, diagnosed (n1 = 76), esophagus (n2 27) medically fit people’s (n3 30) findings investigating have been analyzed. All pa...

H. pylori-induced chronic inflammation is considered the most important cause of gastric cancer. The actual process how chronic inflammation triggers gastric carcinogenesis is still not clear. In this study, neutrophils and relative markers in gastric cancer development were examined with immunohistochemistry and fluorescence RNA in situ hybridization methods. On average, 24 times more neutroph...
