  1. Epidemiologi og etiologi. Gastrointestinal stromal tumor er en uvanlig kreftform med årlig forekomst på 10-15 tilfeller per million (), men er likevel den vanligste subtypen av sarkom ().Sykdommen har lik kjønnsfordeling, og median alder ved diagnose er 65 år ().Gastrointestinal stromal tumor antas å ha sitt histogenetiske opphav i Cajal-celler, som er motilitetsregulerende.

Gastrointestinal stromal tumor (GIST) Gastrointestinal stromal tumors (GISTs) are soft tissue sarcomas that can be located in any part of the digestive system. Their most common sites are the stomach and small intestine. GISTs start in specialized nerve cells located in the walls of your digestive system Gastrointestinal Stromal Tumor (GIST) If you have a gastrointestinal stromal tumor (GIST) or are close to someone who does, knowing what to expect can help you cope. Here you can find out all about gastrointestinal stromal tumors, including risk factors, symptoms, how they are found, and how they are treated

Gastrointestinal stromal tumors. Gastrointestinal stromal tumors (GISTs) start in very early forms of special cells in the wall of the GI tract called the interstitial cells of Cajal (ICCs). ICCs are sometimes called the pacemakers of the GI tract because they signal the muscles in the GI tract to contract to move food and liquid along If your doctor thinks you might have a GIST, you might have some tests that help find the tumor and let your doctor know if it's spread to other parts of your body. Some tests you may have.

Ved gastrointestinal stromal tumor (GIST) er operativ behandling med fullstendig fjerning av svulsten, eneste helbredende metode. Inngrepet er aktuelt for alle pasienter som har helse til å tåle inngrepet. GIST er den vanligste sarkomet i mage- og tarmkanalen. GIST kan forekomme i hele fordøyelseskanalen, men er hyppigst i magesekken (55 til 65 %) og i tynntarmen (20 til 30 %). 5 til 8 %. Gastrointestinal stromal tumors (GIST) are usually found on the stomach or small intestine, but they can be found anywhere in or near the GI tract. Find out about risk factors, symptoms, tests to diagnose, prognosis, staging, and treatment for gastrointestinal stromal tumors

GIST was only recognized as a distinct form of tumor a few decades ago, but advances in the genetic analysis of this tumor has led to progress in its treatment that can be considered a prototype of precision medicine (treating cancers individually based on their genetic make-up rather than with a one-size-fits-all approach) 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 Enlarge Gastrointestinal stromal tumors (GISTs) may be found anywhere in or near the gastrointestinal tract.. Less frequently, GIST may arise in the appendix, gallbladder, pancreas, retroperitoneum, and paravaginal and periprostatic tissues.[] Approximately 20% to 25% of gastric GIST and 40% to 50% of small intestinal GIST are clinically aggressive.[9,10] It has been estimated that.
