Gastrointestinal stromal tumors are the most common primary mesenchymal tumors of the gastrointestinal tract accounting for 0.1%-3.0% of all gastrointestinal malignancies. The stomach is the most common site (60%) followed by the small bowel (30%-35%) particularly jejunum and ileum, colorectum (5%) and rarely affect esophagus and appendix. Most gastrointestinal stromal tumors arise sporadically...
Primitive mesenchymal gastrointestinal tumors without evidence of differentiation are referred to as gastrointestinal stromal tumors. Because gastrointestinal stromal tumors are known for their wide variability in clinical behavior and for the difficulty in determining their malignant potential, numerous studies have been done to define better useful prognostic indicators.1–3 We report a case o...
CONTEXT Gastrointestinal stromal tumors (GISTs) are responsive to sunitinib (the tyrosine kinase inhibitor), this agent is widely used in prevention relapse of GISTs and neo-adjuvant chemotherapy in GIST patients without operation opportunity. The use of these agents has both advantages and disadvantages. On the one hand, it can improve the outcome for patient. On the other hand, it may lead to...
Gastrointestinal stromal tumor is a rare tumor which arises from the whole gastrointestinal tracts and most of it is detected in the stomach. It is uncommon with small intestine originated gastrointestinal stromal tumor and more uncommon with lymphatic metastasis. We experienced an unusual case of the small bowel gastrointestinal stromal tumor during experimental autopsy. Two primary tumors wit...
Gastrointestinal stromal tumors (GISTs) may be defined as morphologically spindle cell, epithelioid, or occasionally pleomorphic mesenchymal tumours of the gastrointestinal tract that usually express the KIT protein and harbour mutation of a gene that encodes for a type III receptor tyrosine kinase (either KIT or PDGFRA). In Caucasian populations their annual incidence is 10 to 15 cases per mil...
The author draws attention to rare tumours of the digestive tract, their symptoms, treatment and prognosis.
Gastrointestinal stromal tumors (GISTs) are mesenchymal tumors of the gastrointestinal tract with immunohistochemical reactivity for CD117 antibody. Gastrointestinal stromal tumor with synchronous gastric cancer is rare. A 69-year-old male presented with one-week history of epigastrium pain and vomit was admitted to our hospital. Subtotal gastrectomy and D2 lymph node dissection were performed,...
