- GIST is a rare type of sarcoma found in the digestive system, most often in the wall of the stomach. Some GISTS behave in a non cancerous (benign) way. Or they can behave in a cancerous (malignant) way.

Gastrointestinal stromal tumor (GIST) is a rare cancer affecting the digestive tract or nearby structures within the abdomen.GI stromal tumor, or GIST cancer, is a sarcoma.ecause primary GISTs in these locations do not arise directly from the GI tract, they are sometimes called “extragastrointestinal” stromal tumors (Reith et al, 2000). When a GIST grows in a location where it is not encased in the peritoneal membranes, it is said to be retroperitoneal.

- Other rare types of cancer in the GI tract include leiomyosarcomas (cancers of smooth muscle cells), angiosarcomas (cancers of blood vessel cells), and peripheral nerve sheath tumors (cancers of cells that support and protect nerves).GISTs are different from these other GI tract cancers.ther rare types of cancer in the GI tract include leiomyosarcomas (cancers of smooth muscle cells), angiosarcomas (cancers of blood vessel cells), and peripheral nerve sheath tumors (cancers of cells that support and protect nerves).

Small Bowel Tumors In the small bowel they are more often malignant than in the stomach. Tumors smaller than 2 cm are usually benign, whereas masses larger than 5 cm are often malignant. Malignant GIST's predominantly grow extraluminally and can show necrosis, hemorrhage, calcification (post therapy) and fistula formation.

- Malignant tumours vary in size and shape. They grow in an uncontrolled, abnormal way and can grow into (invade) nearby tissues, blood vessels or lymphatic vessels. They can interfere with body functions and become life-threatening. Cancer cells can break off and spread to distant locations in the body (metastasize).

Gastrointestinal stromal tumor GISTs are tumors of connective tissue, i.e. sarcomas; unlike most gastrointestinal tumors, they are non epithelial. About 70% occur in the stomach, 20% in the small intestine and less than 10% in the esophagus.

In addition: 1  Scientists are looking into the role of an associated genetic abnormality on the short arm of chromosome 19 that may give rise to this disease.

Salivary Gland Cancer Treatment (Adult) (PDQÂ®)âHealth Professional Version Malignant mesenchymal salivary gland neoplasms include malignant schwannomas, hemangiopericytomas, malignant fibrous histiocytomas, rhabdomyosarcomas, and fibrosarcomas, among others; in the major salivary glands, these neoplasms represent approximately 0.5% of all benign and malignant salivary gland tumors and approximately 1.5% of all malignant tumors.[90,92,93] Of importance is to establish a primary salivary gland origin for these tumors by excluding the possibilities of metastasis and ...

- GISTs of the stomach wall are considered malignant when they exceed 5 to 10 centimeters, have a high rate of cell division, or have metastasized (spread). GISTs of the small bowel are considered malignant if they have any mitoses or are greater than 2 centimeters.

Mucosa-associated lymphoid tissue (MALT) MALT may be the site of solid tumors that develop in LYMPHOMA (sometimes called MALT lymphoma). The most common MALT site for such an occurrence is the gastrointestinal tract. Researchers believe these lymphomas develop when a constant assault, such as a persistent infection, engages the MALT site.

- A potentially life-threatening mass of cancerous cells. Malignant tumors are ambitious. Unlike benign tumors that generally stay put, malignant tumors have two goals in life: …to survive and to conquer new territory. So, if you have a malignant tumor in your colon, it's going to try to work its way through your colon. If successful, it will see where else it can go. This is called metastasizing. In general, malignant tumors grow faster than benign tumors and are more likely to cause health problems.

Gastrointestinal Stromal Tumor (GIST) A GIST tumor that originates elsewhere and then spreads to the liver is still biologically a GIST tumor and not a liver tumor; therefore, GIST tumors in the liver are treated very differently than cancer which starts in the liver (liver cancer).arly symptoms of GIST may go unnoticed. And, because GIST is so rare, primary care physicians may not readily recognize its symptoms. Without early detection and treatment, the primary tumor can grow very large or spread (metastasize) to other locations in the body, such as the liver or abdominal cavity.

- Removal of the tumor is the primary treatment for GISTs. Mayo Clinic surgeons remove small tumors through small incisions using laparoscopic surgery. If your GIST is large or attached to other organs, a more-extensive operation may be necessary and may involve removing parts of the affected organs. The surgeon may also remove small amounts of tissue outside your GIST to avoid tumor rupture and prevent future obstruction to your digestive tract.

What is GIST? GIST is an abbreviation for GastroIntestinal Stromal Tumour. 1  Gastrointestinal means that it occurs in the digestive tract, anywhere from the oesophagus to the rectum i.e. the gullet, stomach, intestines. So, for example, a GIST in or near the colon is not cancer of the colon because it does not occur in the functioning part of the colon but in the tissues which support the colon.

Gastrointestinal Stromal Tumors Treatment (PDQÂ®)âPatient Version The metastatic tumor is the same type of tumor as the primary tumor. For example, if a gastrointestinal stromal tumor (GIST) spreads to the liver, the tumor cells in the liver are actually GIST cells. The disease is metastatic GIST, not liver cancer.

Gastrointestinal stromal tumor Print All Open All Close All. A gastrointestinal stromal tumor (GIST) is a type of tumor that occurs in the gastrointestinal tract, most commonly in the stomach or small intestine. The tumors are thought to grow from specialized cells found in the gastrointestinal tract called interstitial cells of Cajal (ICCs) or precursors to these cells. GISTs are usually found in adults between ages 40 and 70; rarely, children and young adults develop these tumors.
