Tyrosine kinases-inhibitors targeting vascular endothelial growth factor (VEGF)-receptors (RTKIs) are increasingly used in oncology in several metastatic tumor types. These agents are featured by toxicities including hypertension. According to a new insight, sodium in response to a high dietary
The prognosis of gastric GIST depends on various tumor factors with the most important being the mitotic index and tumor necrosis. Imatinib therapy has revolutionized the treatment of advanced GIST.
They have been the subject of much controversy in terms of their histogenesis, classification,
Even though the prognosis of advanced GIST has been tremendously improved by the introduction of tyrosine kinase inhibitors, the vast majority of patients will develop secondary resistance to these agents.
The therapeutic options of patients with advanced GIST with resistance (or intolerance) to
Most patients with Metastatic/unresectable Gastrointestinal stromal tumors will progress on the treatment of tyrosine kinase inhibitor(TKI) including Imatinib and Sunitinib.
Entacapone and imatinib can each inhibit the role of v-kit Hardy-Zuckerman 4 feline sarcoma viral oncogene homolog(KIT) which
Imatinib is the first-line treatment for advanced GIST with a satisfactory response rate, but complete remission rarely happens. Besides, drug resistance can occur during the treatment and the median time of drug resistance is about 20-24 months. Once drug resistance occurs, the patient's condition
Patients treated with targeted therapies by tyrosine kinase inhibition (TKI) almost always show different response patterns than tumors treated with cytotoxic chemotherapy. Tumor manifestations treated with targeted therapies often show only minor measurable changes in tumor size despite inhibition
While targeted therapy with imatinib has significantly improved survival for patients with inoperable and metastatic gastrointestinal stromal tumors (GIST), the majority will eventually progress after a median of 20-26 months. Standard second-line treatment with sunitinib has a response rate of 7%,
Background
- Loss of activity of the Krebs cycle components succinate dehydrogenase (SDH) complex or fumarate hydratase (FH), has been identified as a mechanism of tumorigenesis in subsets of gastrointestinal stromal tumor (GIST), pheochromocytoma and paraganglioma (PHEO/PGL), and renal cell
BACKGROUND:
- Gastrointestinal stromal tumor (GIST) is the most common mesenchymal neoplasm of the gastrointestinal tract, and traditional cytotoxic chemotherapy is not effective. Patients with Neurofibromatosis 1 (NF1) have an increased risk of developing GIST, and surgery remains the only standard
PRIMARY OBJECTIVES:
I. To collect preliminary information to help design a study to look at longitudinal changes in markers of ovarian reserve and menstruation in premenopausal women undergoing tyrosine kinase inhibitors (TKI) therapy.
SECONDARY OBJECTIVES:
I. Evaluate ovarian response to controlled
Glioblastoma multiforme (GBM), the most common primary brain tumor in adults is known for its highly invasive and angiogenic profile. Despite advances in different modalities of GBM treatment, the overall prognosis of GBM remains dismal. The current standard of care is Radiation Therapy (RT) at a
