PI-103 of Asp Val These tumors usually resistant to treatment with imatinib

Re largely missense mutations are the substitution of Asp Val These tumors usually resistant to treatment with imatinib. Missense mutation in exon 14 was also is the substitution of Asn to Lys or PI-103 Tyr been reported. These tumors have a better prognosis than the last. On the other hand, the mutations are in exon 12 U Only rarely. 2.3. Wild type. 5% to 15% of GISTs home kit or PDGFRA mutations and are used as the wild-type GIST known. The tumors can k Positive for CD117 and can be f Erroneously marked as GIST Imitanib sensitive. However, these tumors are less sensitive to imatinib treatment with a worse prognosis. It was suggested that these tumors, the insulin growth factor-1 receptor mutation, which is especially in adult and pediatric GIST expressed wild-type host.
The downregulation of IGF1R activity t would cytotoxicity t or apoptosis induced through experimental studies. Third Clinical Features The clinical spectrum of Pr Presentation is broad in GIST. It is largely dependent Ngig of the tumor size E and location. Symptoms usually cause GIST gr eren, More than 6 inches in diameter. The h Most frequent presentation GSK1904529A of GIST is abdominal pain and / or gastrointestinal bleeding. It can be acute, ‘How melena, H Matemesis entered, bleeding or chronic insidious At no Chemistry. GIST k Can also cause secondary symptoms R to Mass Effect, including normal S Ttigungsgefhl, flowering increases and abdominal pain. In our review of the F Ll the abdominal pain is the hour Most frequent complaint, mass effects and gastrointestinal bleeding is followed.
Other symptoms observed in our study go Ren abdominal pain, chest pain, small bowel obstruction, dysuria, VER Nderter stool, nausea and weight loss. About 70% of GIST patients have symptoms, the remaining 20% to 30% are diagnosed incidentally or at autopsy. These results correlate well with our observation that were discovered five of 32 reported cases of GIST by chance. About 20% to 25% of gastric ulcers and 40% to 50% of the small bowel stromal tumors are malignant clinically. Themost commonmetastatic sights go Rt Bauchh cave, liver, bone and soft tissues, and rare. GIST rarely metastasize if not so at the lymph nodes and skin. In the case reports we reviewed, the Bauchh cave which h Most frequent metastatic site of the liver and the pancreas was followed. No metastases were detected in the lymph nodes. 3.1.
GIST syndromes and familial Ren GIST. GIST family, neurofibromatosis type 1, Carney triad, and recently, Stratakis Carney triad: Less than 5% of GIST can be one of the four tumor syndromes are associated. GIST syndrome family has been identified and reported worldwide in different families. FGS is an autosomal dominant model to accommodate multiple, sometimes diffuse GISTs. The clinical picture of the FGS go Ren hyperpigmentation, one obtains Hte number of N Vi, urticaria pigmentosa, and / or systemic mastocytosis. Dysphagia, which is physiologically different from true achalasia has been reported in affected family Budding Uncircumcised of FGS. Familial syndrome Rer GIST is for weight Similar in multiple GISTs in the small intestine and to a lesser extent, stomach. It was also in the feeder Hre and rectum described. Morphologically, these tumors are indistinguishable from sporadic GISTs are characterized and spirit
