1. Gastrointestinal stromal tumors. Pathogenetic mechanisms, phenotypic characterization and prognosis
Sammanfattning : Gastrointestinal stromal tumor (GIST), the most common non-epithelial neoplasm of the gastrointestinal tract, has historically been problematic both conceptually and clinically. Recently, GIST has been shown to share phenotypic features with the interstitial cells of Cajal (ICC), including the almost uniform expression of the tyrosine kinase receptor KIT. LÄS MER
2. Pancreatic Endocrine Tumors and GIST - Clinical Markers, Epidemiology and Treatment
Sammanfattning : Pancreatic endocrine tumors and gastrointestinal stromal tumors are rare. Evidence regarding prognostic factors, and in the former also treatment, is scarce. We evaluated the survival and prognostic factors in a consecutive series of 324 patients with pancreatic endocrine tumors treated at a single institution. LÄS MER
3. Molecular mechanisms of imatinib resistance in gastrointestinal stromal tumor with focus on microRNAs
Sammanfattning : Gastrointestinal stromal tumor (GIST) is mainly initialized by mutations in receptor tyrosine kinase genes KIT or PDGFRA. The development of imatinib, a small molecule inhibitor that targets these tyrosine kinase receptors, remarkably improved patient outcome. LÄS MER
4. Endosonography and pretreatment tumor profiling - from sampling, staining, to sequencing
Sammanfattning : Background and aims: Endosonography-guided fine needle aspiration (EUS-FNA) is imperfect in diagnosing solid pancreatic lesions (SPL) and subepithelial lesions (SEL) including gastrointestinal stromal tumors (GIST). In GISTs, imatinib therapy is effective only in variants of oncogenes KIT and PDGFRA. LÄS MER
5. Novel aspects of the molecular biology of gastrointestinal stromal tumors
Sammanfattning : The gastrointestinal stromal tumor (GIST) is the most common mesenchymal tumor in the gastrointestinal tract (GI). Historically, these tumors were commonly mistaken for myogenic and neurogenic masses, and then eventually came to be recognized as a distinct type of soft-tissue sarcoma through ultrastructural findings and specific immunomarkers.
