gastrointestinal stromal tumors/headache

Pituitary carcinomas are rare diseases defined as pituitary tumors with metastases. In this report, we describe a case of malignant prolactinoma with liver metastases masquerading as metastatic gastrointestinal stromal tumor (GIST). A 54-years-old woman received dopamine agonists for

OBJECTIVE Heat shock protein 90 (HSP90) is required for the proper folding, function, and stability of various client proteins, two of which (KIT and PDGFRα) are critical in the pathogenesis and progression of gastrointestinal stromal tumors (GIST). This phase I study investigated the safety and

Imatinib (Gleevec) is a biological agent that is approved for the treatment of chronic myeloid leukemia (CML) as well as gastrointestinal stromal tumor (GIST). The most frequently seen adverse effects in patients treated with imatinib include superficial edema, muscle cramps, musculoskeletal pain,

BACKGROUND Intracranial metastases of gastro intestinal tumors are very rare. To the best of our knowledge only few cases were reported on the literature. METHODS We describe the case of 66-year-old male that presented with headache and vomiting. Physical examination found a kinetic cerebellar

Tyrosine kinase receptors play an important role in tumor angiogenesis and, their implication in epithelial thyroid tumor growth has been highlighted. Sunitinib is a novel tyrosine kinase inhibitor, approved in 2006 by Food and Drug Administration for the treatment of advanced renal cell and

Imatinib (Gleevec; STI-571) is a tyrosine-kinase inhibitor (TKI) used in the treatment of multiple cancers, most notably Philadelphia chromosome-positive (Ph+) chronic myelogenous leukemia (CML) as well as gastrointestinal stromal tumor (GIST). The most common adverse effects with imatinib include

BACKGROUND Imatinib is a tyrosine kinase inhibitor that has been established as a highly effective therapy for chronic myelogenous leukemia and gastrointestinal stromal tumors. A new generic, once-daily 400-mg tablet of imatinib has been developed by a pharmaceutical company in Argentina, where the

BACKGROUND Nilotinib, a second-generation tyrosine kinase inhibitor (TKI) formerly known as AMN107, was approved by the US Food and Drug Administration (FDA) on October 29, 2007, for the treatment of adult patients with chronic-phase (CP) and accelerated-phase (AP) Philadelphia chromosome-positive

Although anticancer drugs have existed for over 50 years, targeted drugs have only recently been marketed, and their side effects may not be completely understood. The patient is a 56-year-old woman with a gastrointestinal stromal tumor who presented with headache, nausea, and vomiting lasting 2

OBJECTIVE To determine the maximum tolerated dose (MTD) dose-limiting toxicity, and pharmacokinetic and pharmacodynamic profile of TKI258 (formerly CHIR-258). METHODS A phase I dose escalating trial in patients with advanced solid tumors was performed. Treatment was initially as single daily doses

The paraganglioma (PGL) syndromes types 1-5 are autosomal dominant disorders characterized by familial predisposition to PGLs, phaeochromocytomas (PCs), renal cell cancers, gastrointestinal stromal tumours and, rarely, pituitary adenomas. Each syndrome is associated with mutation in a gene encoding

OBJECTIVE SU5416 (semaxanib) is a small molecule inhibitor of the vascular endothelial growth factor (VEGF) receptor-2 and KIT receptor tyrosine kinases. This Phase II study was conducted to investigate the safety and efficacy of SU5416 for patients with soft tissue sarcomas. METHODS Thirteen
