The reported associations with gastric adenocarcinoma and seropositivity to different Helicobacter pylori antigens using multiplex serology have not been consistent across studies. We aimed to investigate the association between 15 different multiplex serology antigens and the risk of gastric cardia (GCA) and gastric noncardia (GNCA) adenocarcinomas in northeastern Iran, a population with high ...

Although gastric adenocarcinoma continue to be the second continues to be the second cause of death worldwide, its incidence and mortality appear to have decreased in recent decades. Despite this decline, adenocarcinomas from proximal stomach tend to be more frequent during the last three decade. Adenocarcinomas with this location it seems that are a different, specific subtype of gastric carci...

Prolonged inflammation or irritation due to renal calculi can induce glandular metaplasia of the urothelium and even malignant neoplasm. Primary adenocarcinoma in pelvicalyceal system is a rare tumor in such patients. Here, a case of carcinoembryonic antigen (CEA) positive primary tubulovillous adenocarcinoma in pelvicalyceal system is reported. A 57-year-old male with right abdominal pain and ...

A gastric inverted hyperplastic polyp is a rare type of gastric polyp and is characterized by downward growth of a variety of mucosal components into the submucosa. The polyp consists of columnar cells resembling foveolar epithelium and pyloric gland epithelium and can coexist with gastritis cystica profunda. Frequently, adenocarcinoma can coexist, but the relation is not clear. A 77-year-old m...

Gastric adenocarcinoma after gastric bypass for morbid obesity is rare but has been described. The diet restriction, weight loss, and difficult assessment of the bypassed stomach, after this procedure, hinder and delay its diagnosis. We present a 52-year-old man who underwent Roux-en-Y gastric bypass 2 years ago and whose previous upper digestive endoscopy was considered normal. He presented wi...

gastric cardia adenocarcinoma (gca)is one of the few malignancies with unexplained reasons that have increased sharply in developed countries. the purpose of this review was to determine the pathways in gca to identify new biomarker. so by comparing gene expression in gca group with normal control identified important pathways. gene expression data were extracted from the beforehand investigati...

BACKGROUND Gastric and colorectal adenocarcinoma are the second and the fifth most common cancers in Iran, respectively. Expression of cytokeratin 7 (CK7) is established in most malignancies including gastric and colorectal adenocarcinoma. Demonstration of Ck7 could be related to prognostic factors and help to the better management of the patients. The objective of our study was to evaluate the...

BACKGROUND The rapidly rising incidence and the striking male predominance are as yet unexplained features of oesophageal and gastric junction adenocarcinoma. Few and underpowered studies have examined the impact of female reproductive factors on risk of these adenocarcinomas in women. We therefore pooled data on women from four population-based case-control studies to examine the association o...

BACKGROUND The clinical significance of fibroblast growth factor 1 (FGF1) has been revealed in several cancers, including ovarian cancer, breast cancer, and bladder cancer. However, the clinical significance of FGF1 in gastric adenocarcinoma has not been explored. PATIENTS AND METHODS In our experiments, we systematically evaluated FGF1 expression in 178 cases of gastric adenocarcinoma with i...
