Gastrointestinal stromal tumors (GISTs) are the most frequent neoplasms of mesenchymal origin affecting the gastrointestinal tract. GISTs quite frequently co-exist with other primary tumors in up to 3...
Gastrointestinal stromal tumors (GISTs) are mesenchymal tumors that express type 3 tyrosine kinase receptors and are thought to develop from the neoplastic transformation of the interstitial Cajal cel...
Gastrointestinal stromal tumors (GISTs) are the most common soft tissue tumors of the GI tract. Studies have been published reporting additional neoplasms in GIST patients. This study aimed to evaluat...
Gastrointestinal stromal tumors (GISTs) are rare, but represent the most common mesenchymal neoplasms of the gastrointestinal tract. EPIdemiology GIST, is an observational multicenter longitudinal fol...
FDA-approved products for patients with unresectable or metastatic GIST include therapies such as imatinib and sunitinib. Although there are FDA-approved products for the treatment of adva...
Patients with metastatic or locally advanced gastrointestinal stromal tumors (GIST) who develop resistance against the two hitherto approved drugs for this disease, the tyrosin kinase inhi...
For patients of GIST (Gastrointestinal Stromal Tumor), Imatinib has been widely used in GIST with KIT or PDGFRA sensitive mutations. From clinical points of view, individual differences of...
A biospecimen collection study from individuals with EGFR mutant cancers resistant to EGFR TKIs or those harboring an Exon 20 insertion mutation.
Evaluate the safety and tolerability of AMG 510 in adult subjects with KRAS p.G12C mutant solid tumors. Estimate the maximum tolerated dose (MTD) and/or a biologically active dose (eg, re...
All tumors in the GASTROINTESTINAL TRACT arising from mesenchymal cells (MESODERM) except those of smooth muscle cells (LEIOMYOMA) or Schwann cells (SCHWANNOMA).
A family of mesenchymal tumors composed of histologically and immunohistochemically distinctive perivascular epithelioid cells. These cells do not have a normal anatomic homolog. (From Fletcher CDM, et. al., World Health Organization Classification of Tumors: Pathology and Genetics of Tumors of Soft Tissue and Bone, 2002).
Tumors or cancer of the GASTROINTESTINAL TRACT, from the MOUTH to the ANAL CANAL.
A test used to determine whether or not complementation (compensation in the form of dominance) will occur in a cell with a given mutant phenotype when another mutant genome, encoding the same mutant phenotype, is introduced into that cell.
Rare mixed tumors of the brain and rarely the spinal cord which contain malignant neuroectodermal (glial) and mesenchymal components, including spindle-shaped fibrosarcoma cells. These tumors are highly aggressive and present primarily in adults as rapidly expanding mass lesions. They may arise in tissue that has been previously irradiated.
