BACKGROUND/AIMS The incidence of gastric remnant carcinoma does not decrease after partial gastrectomy The aim of this study was to evaluate the clinical features and prognosis of gastric remnant carcinoma after treatment. METHODOLOGY Among 412 gastric carcinoma patients who were admitted to our hospital 21 were found to have gastric remnant carcinoma. We analyzed their clinicopathological fe...
The activation of Hedgehog (Hh) signaling has been implicated in the growth of various tumor types, including gastric carcinoma. However, the precise mechanisms of Hh activation and suppression of tumor growth by the blockade of Hh signaling in gastric carcinoma cells remain unknown. The aim of this study was to elucidate the mechanism of abnormal Hh signaling and the key molecules contributing...
The present report investigated the correlation between the expression levels of matrix metalloproteinase (MMP)-9 in gastric carcinoma patients and the clinicopathological characteristics. Forty-five samples of gastric carcinoma and distal gastric mucosa tissue, and 10 samples of healthy gastric mucosa tissue were analyzed using semi-quantitative polymerase chain reaction, as well as immunohist...
OBJECTIVE To study the five years survival rate after resection for gastric carcinoma. METHODS Fifty six patients with gastric carcinoma in different stages were followed up for 5 years after gastric surgery to see recurrence, complications and survival rate. RESULTS Of the 56 patients, 6 underwent total gastrectomy, 50 partial gastrectomy, 7 Billroth I and 43 modified DI resection with Bil...
Mixed adenoneuroendocrine carcinoma (MANEC) is a rare disease, which mostly occurs in the gastrointestinal tract and pancreas. Here we report a case of gastric MANEC with tri-lineage differentiation in which only the neuroendocrine component had metastasized to the liver. Liver and gastric masses were detected by abdominal computed tomography, and the preoperative relationship between liver and...
A gastric carcinoma with the endoscopic features resembling submucosal tumor (SMT) is rare, and reportedly account for only 0.1% to 0.63% of all resected gastric carcinomas. The preoperative diagnosis of SMT-like gastric carcinoma is challenging, and thus, diagnosis is usually made intraoperatively or postoperatively. Furthermore, mucinous adenocarcinoma is an uncommon histologic subtype of gas...
BACKGROUND Of all human cancers, gastric carcinoma is the one of the leading causes of death. Helicobacter pylori is considered a major etiologic agent of this disease. Spontaneously occurring gastric carcinoma is a rare diagnosis in nonhuman primates. A 2011 case report documented a high incidence of gastric adenocarcinoma in a closed colony of captive sooty mangabeys (Cercebus atys). However,...
BACKGROUND The significance of carcinoembryonic antigen-related cell adhesion molecule 7 (CEACAM7) expression in gastric carcinoma and precancerous lesions and its correlation with CEA expression has rarely been previously investigated. METHODS CEACAM7 and CEA expression was detected by immunohistochemistry in consecutive sections of 345 subjects with gastric carcinoma and precancerous lesion...
BACKGROUND Hereditary diffuse gastric carcinoma is an autosomal dominant cancer syndrome associated with mutations of the E-cadherin gene (CDH1). E-cadherin is normally involved in cell-cell adhesion, so it not surprising that individuals with this syndrome are predisposed to develop malignancies with dyshesive morphologies at a young age, such as diffuse (signet ring cell) gastric carcinoma an...
