STI571 is a 2-phenylaminopyrimide derivative that was designed as an Abl tyrosine kinase inhibitor, but it is also effective against platelet-derived growth factor receptor (PDGFR) and c-Kit tyrosine kinase. Recent studies have demonstrated that STI571 inhibits the growth of several tumors in which
OBJECTIVE
To describe potential beneficial effects of tyrosine kinase inhibitor in the treatment of unresectable/metastatic fibrous histiocytoma.
METHODS
We report a case of advanced stage fibrous histiocytoma with locally recurrent disease plus lung and bone metastatic deposits. Patient was treated
Soft tissue sarcomas (STS) represent a diverse group of histologic subtypes with targetable molecular alterations, often treated as a single disease. Sunitinib malate is a multitargeted receptor tyrosine kinase inhibitor active in other solid tumors carrying similar alterations (i.e., imatinib
Tyrosine kinase inhibitors against the receptors of vascular endothelial growth factor (VEGFR), epidermal growth factor (EGFR) and the platelet derived growth factor (PDGFR) are increasingly used in the treatment of progressive cancers. However, the expression of these receptors especially in lung
BACKGROUND
Malignant fibrous histiocytoma (MFH) is one of the most common high-grade sarcomas in bone and soft tissue and, due to its chemo-resistance, the prognosis of the disease is poor. ST1571 is a tyrosine kinase inhibitor that was initially developed as a BCR/ABL inhibitor for chronic myeloid
This report documents for the first time the in vitro autophosphorylation of purified 68 kDa hyaluronate binding protein in presence of [32P] ATP. The rate of phosphorylation is proportional to the concentration of protein and to the time of incubation up to 5 min. By both phosphoamino acid and
OBJECTIVE
The new classification of malignant fibrous histiocytoma leaves only a small group of tumors without further line of differentiation, so-called pleomorphic sarcomas, not otherwise specified (NOS) as a pseudo-entity. This study focused on these tumors and analyzed the association of gene
BACKGROUND
Malignant fibrous histiocytoma (MFH) is one of the most diffuse and aggressive tumors among soft tissue sarcomas in adults, but still poorly characterized from the molecular viewpoint. MFH cell proliferation is inhibited selectively by imatinib mesylate, a tyrosine kinase inhibitor. The
Malignant fibrous histiocytoma (MFH) is the most common soft-tissue sarcoma in late adult life. Unfortunately, advanced MFH has a poor prognosis due to a lack of effective drugs. We present here a case of advanced MFH with partial response to apatinib, a new potent oral small-molecule tyrosine
Cytokines trigger activation of different lymphocyte populations, resulting in augmentation of humoral and cell-mediated immunity. We have examined the role of IFN-gamma in mediating AK-5 tumor regression. High levels of circulating IFN-gamma and IL-2 marked the process of regression. Moreover,
Anlotinib is a novel, orally administered, multitarget receptor tyrosine kinase inhibitor. It functions by inhibiting tumor angiogenesis and proliferative signaling pathways. In this study, we aimed to investigate the efficacy and safety of anlotinib plus epirubicin in a sarcoma Sarcomas comprise a heterogeneous and biologically diverse group of malignant neoplasms having as a common denominator their origin from mesenchymal cells. Head and neck sarcomas account for 4 to less than 20% of total body sarcomas depending on the criteria, such as age of patients (pediatric vs
Anaplastic lymphoma kinase (ALK) is a receptor tyrosine kinase that has been implicated in the pathogenesis of a variety of neoplasms. As suggested by its name, ALK was first described as part of a translocation product in cases of anaplastic large-cell lymphoma, with other genetic and cytogenetic
We have screened mutations of the beta-catenin gene by using the polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP) method in 62 malignant bone and soft-tissue tumors, including malignant fibrous histiocytomas (MFHs), osteosarcomas, synovial sarcomas, liposarcomas,
BACKGROUND
Little is known about the expression of receptor tyrosine kinases in adult soft tissue sarcomas (STS). In the current study, the authors analyzed the expression of epidermal growth factor receptor (EGFR), ERBB2, and KIT in 281 patients with STS who were treated in a single institution.
