Neuroendocrine tumors (carcinoids) are tumors originating from neuroendocrine cells. The distinction between different types of gastric carcinoids is important for their management. We present the case of a 38-year old woman with type 1 gastric neuroendocrine tumors (NETs) associated with autoimmune atrophic gastritis. The management of these tumors has not been yet codified and different therapeutic strategies have been suggested. A proper evaluation before therapy is indicated in order to rule out both the malignant transformation as well as the presence of synchronous lesions, such as dysplasia or gastric adenocarcinoma. We describe our diagnostic and therapeutic strategies with references to previously published reports. [ABSTRACT FROM AUTHOR]

Background and Aim: Gastric intestinal metaplasia represents a risk factor for intestinal type of gastric cancer. Gastric intestinal metaplasia seems to be associated with Helicobacter pilory infection in relatives of patients with gastric cancer. The aim of this study was to determine the prevalence, clinical, endoscopic and histological features of gastric intestinal metaplasia. Material and Methods: We retrospectively analyzed the esophagogastroduodenoscopies with biopsies performed between January 1, 2014 and October 31, 2014. Collected and analyzed data included age, gender, symptoms, endoscopic and histological findings. Results: Four hundred eighty-two patients were included in the study. One hundred thirty-seven patients had gastric intestinal metaplasia, which presented a prevalence was 28,4%. A similar distribution between gender was observed with a significant increase of gastric intestinal metaplasia with age (p=0,0001). Regarding the indication for endoscopy, the prevalence of gastric intestinal metaplasia was: 17 % among patients with dyspeptic syndrome, 2 % in patients with anemia and 5 % in patients examined for other symptoms. Endoscopic findings showed gastric intestinal metaplasia was significantly associated with atrophic gastritis (p=0.0001), erythematous gastritis (p=0.0079), while there was no association with erosive gastritis (p=0.24) and peptic ulcer (p=0.19). Conclusions: Gastric intestinal metaplasia is frequently recorded in patients undergoing in esophagogastroduodenoscopies with associated biopsies. Endoscopic findings like erythema and atrophy is strongly associated with gastric intestinal metaplasia emphasizing the importance of sampling biopsies. [ABSTRACT FROM AUTHOR]

Background & Aims: Over the past few decades, the incidence of adenocarcinomas of the gastroesophageal junction has rapidly increased. Barrett's esophagus is a risk factor for esophageal adenocarcinoma, but the role of intestinal metaplasia of the gastric cardia as a precursor in cardia-related cancer is controversial. The aims of the present study were to examine the prevalence of intestinal metaplasia in the gastroesophageal junction and to evaluate the clinical, endoscopical and histological features of patients with intestinal metaplasia in the gastric cardia and patients with Barrett's esophagus. Methods: 286 consecutive patients undergoing gastroduodenoscopy were enrolled in a prospective study. Biopsy specimens were performed in the distal esophagus, squamocolumnar junction, gastric cardia, gastric corpus and antrum. Results: We identified 44 patients (15.3%) with intestinal metaplasia in biopsies from gastric cardia and 24 patients (8.3%) with Barrett's esophagus. Cardia intestinal metaplasia was significantly associated with older age (p=0.03), with intestinal metaplasia in the antrum (p=0.017) and H. pylori infection (p<0.0001). Severe chronic cardia inflammation increased the presence of cardia intestinal metaplasia 6.2 fold (OR=6.288; p<0.0001). Patients with Barrett's esophagus were predominantly men. Barrett's esophagus presence significantly correlated with reflux symptoms(p<0.0001), endoscopic esophagitis (p<0.0001) and hiatal hernia >2 cm (p=0.002). No patient had dysplasia in the gastroesophageal region. Conclusions: Presence of intestinal metaplasia at the gastroesophageal region correlated with reflux symptoms and endoscopic signs of reflux disease in patients with Barrett's esophagus and with H.pyloriinfection and distal intestinal metaplasia in patients with cardia intestinal metaplasia.
