2. Gastrinoma - Wikipedia

   en.wikipedia.org/wiki/Gastrinoma

   Gastrin is secreted by the G cells. G cells are primarily found in the pyloric antrum but can also be found in the duodenum and the pancreas. [12] The primary function of gastrin is to induce the release of hydrochloric acid (HCl) from the parietal cells located in the fundus of the stomach.

3. Stomach cancer - Wikipedia

   en.wikipedia.org/wiki/Stomach_cancer

   Cancer of the stomach is difficult to cure unless it is found at an early stage (before it has begun to spread). Unfortunately, because early stomach cancer causes few symptoms, the disease is usually advanced when the diagnosis is made. [80] Treatment for stomach cancer may include surgery, [81] chemotherapy, [13] or radiation therapy. [82]

4. Atrophic gastritis - Wikipedia

   en.wikipedia.org/wiki/Atrophic_gastritis

   Achlorhydria induces G cell (gastrin-producing) hyperplasia, which leads to hypergastrinemia. Gastrin exerts a trophic effect on enterochromaffin-like cells (ECL cells are responsible for histamine secretion) and is hypothesized to be one mechanism to explain the malignant transformation of ECL cells into carcinoid tumors in AMAG.

5. G cell - Wikipedia

   en.wikipedia.org/wiki/G_cell

   A G cell or gastrin cell is a type of cell in the stomach and duodenum that secretes gastrin. It works in conjunction with gastric chief cells and parietal cells. G cells are found deep within the pyloric glands of the stomach antrum, and occasionally in the pancreas [1] and duodenum. The vagus nerve innervates the G cells.

6. Gastrointestinal cancer - Wikipedia

   en.wikipedia.org/wiki/Gastrointestinal_cancer

   Squamous cell cancer, upper oesophagus. Gastrointestinal cancer refers to malignant conditions of the gastrointestinal tract (GI tract) and accessory organs of digestion, including the esophagus, stomach, biliary system, pancreas, small intestine, large intestine, rectum and anus. The symptoms relate to the organ affected and can include ...

7. Helicobacter pylori - Wikipedia

   en.wikipedia.org/wiki/Helicobacter_pylori

   Helicobacter pylori colonizes the stomach for decades in most people, and induces chronic gastritis, a long-lasting inflammation of the stomach. In most cases symptoms are never experienced but about 10–20% of those infected will ultimately develop gastric and duodenal ulcers, and have a possible 1–2% lifetime risk of gastric cancer. [65]
