Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal neoplasms of the gastrointestinal tract. GISTs arise in the smooth muscle pacemaker interstitial cell of Cajal, or similar cells. [2] They are defined as tumors whose behavior is driven by mutations in the KIT gene (85%), [2] PDGFRA gene (10%), [2] or BRAF kinase (rare).
Gastrointestinal stromal tumors (GISTs) form in the soft mesenchymal tissue of the gastrointestinal tract and form from the rapid growth of interstitial cells of Cajal (ICCs). GISTs are the most common type of tumor found in the gastrointestinal tract, usually located in the small intestine or stomach. [ 1 ]
Cancer of the stomach, also called gastric cancer, is the fourth-most-common type of cancer and the second-highest cause of cancer death globally. [2] Eastern Asia (China, Japan, Korea, Mongolia) is a high-risk area for gastric cancer, and North America, Australia, New Zealand and western and northern Africa are areas with low risk. [5]
Stomach cancer, also known as gastric cancer, is a malignant tumor of the stomach. It's a cancer that develops from the lining of the stomach . [ 10 ] Most cases of stomach cancers are gastric carcinomas , which can be divided into a number of subtypes, including gastric adenocarcinomas . [ 2 ]
In a benign tumor, the proliferated cells stay in one location where they do not impact or spread to other surrounding tissues. Malignant tumors, on the other hand, are capable of spreading throughout the entire body, causing new tumors to appear. This process is called metastasis, and is a hallmark of cancerous tumors. [2]
Carney triad (CT), named for J Aidan Carney, is considered to be a specific type of multiple endocrine neoplasia (MEN). The three classically associated tumors are a subset of gastric epithelioid leiomyosarcoma (it is now known that this subset is actually gastrointestinal stromal tumor arising from the interstitial cells of Cajal), pulmonary chondroma, and extra-adrenal paraganglioma.
