Gastric Tumors - KSUMSC

Gastrointestinal Stromal Tumors (GISTs) Stromal or mesenchymal neoplasms typically present as subepithelial neoplasms (submucosal). Originates from the interstitial cells of Cajal (ICCs), sometime referred to as the gastrointestinal pacemaker cells they are the ones that manage the peristalsis.

GIST: Sequencing Treatment and Case Report Evolution

Gastrointestinal Stromal Tumor (GIST) is the most frequent mesenchymal tumor of the gastrointestinal tract; its most common site is the stomach (50-60%), followed by small bowel (20-30%), and large bowel (10%), being less frequently found in the retroperitoneum, esophagus, omentum, and mesentery [1-4].


Cancer Society document, Gastrointestinal Stromal Tumors. Lymphomas: These are cancers of immune system cells that typically develop in lymph nodes, but they may also start in the colon and rectum or other organs. Information on lymphomas of the digestive system is included in the separate American Cancer Society document, Non-Hodgkin Lymphoma.

Adrenal gland tumors known as pheochromocytomas. The adrenal glands are located on top of each kidney, and they produce important hormones. Blood cancer (leukemia). Digestive tract tumors known as gastrointestinal stromal tumors. Neurofibromatosis type 1, is hereditary, which means it can be passed from parents to children in a family.


tissue beneath the skin in which some cells start growing out of control). What is Gastrointestinal Stromal Tumors (GIST)? GIST is a type of cancer of the Gastrointestinal (GI) system (stomach and the bowels) that arises from uncontrolled cell growth of the supporting tissue of these organs. A GIST may occur anywhere along the GI system.


10% of patients do not have a detectable mutation in either KIT or PDGFRA. In particular, GISTs that occur in pediatric patients are nearly always wild-type for both genes (11A). Recent data suggest a possible correlation between imatinib response and the type of mutation, as tumors with an exon 9 mutation or wild-type KIT are less likely to

What is a GIST? Gastrointestinal stromal tumor (GIST) is a rare cancer usually affecting the diges- tive tract or occasionally nearby structures within the abdomen. GIST is a type of sarcoma. Sarcomas are tumors that develop in tissues that connect, support, or surround other structures and organs of the body.


Soft tissue sarcomas are cancers of the connective tissues that hold organs together. GIST is a soft tissue sarcoma that can start in almost any part of the digestive system, most commonly in the stomach or small intestine.

of gastrointestinal stromal tumor (GIST). Tumor suppressor genes Tumor suppressor genes are normal genes that slow down cell division, repair DNA mistakes, or tell cells when to die (a process known as apoptosis or programmed cell death). When tumor suppressor genes don't work properly, cells can grow out of control, which can lead to cancer.

Treating Gastrointestinal Stromal Tumors

Gastrointestinal stromal tumor (GIST) These are rare tumors that seem to start in cells in the wall of the stomach called interstitial cells of Cajal. Some are non-cancerous (benign); others are cancerous. Although these tumors can be found anywhere in the digestive tract, most (70%) occur in the stomach. For

Signs and Symptoms of GastrointestinalStromal Tumors Most gastrointestinal stromal tumors (GISTs) develop within the wall of the stomach orsmall intestine. These tumors often grow into the empty space inside thegastrointestinal (GI) tract, so they might not cause symptoms right away unless they arein a certain location or reach a certain size.

Introduction The gastrointestinal stromal tumors (GIST) are the most frequent mesenchymal tumors of the gastrointestinal tract. The surgery of resectable gastric GIST is the primary therapy for these tumors, but the decision regarding the surgical radicality of the procedures is still a point of discussion among surgeons and oncologists.
