Is 99m Tc-methylene diphosphonate bone scintigraphy a sensitive method for detecting bone lesions in multiple myeloma?
Background: Bone lesion in multiple myeloma (MM) is most commonly presented as a lytic lesion in this disease. Determination of extent of bone lesions in MM is necessary to follow-up the patients. Whole body bone scan with 99m, Tc-methylene diphosphonate (MDP) has a lower sensitivity than other modalities. Methods: From the patients with MM admitted to Ayatollah Rouhani Hospital of Babol-Iran ...
متن کاملBruton tyrosine kinase is a therapeutic target in stem-like cells from multiple myeloma.
Ibrutinib (Imbruvica), a small-drug inhibitor of Bruton tyrosine kinase (BTK), is currently undergoing clinical testing in patients with multiple myeloma, yet important questions on the role of BTK in myeloma biology and treatment are outstanding. Using flow-sorted side population cells from human myeloma cell lines and multiple myeloma primary samples as surrogate for the elusive multiple myel...
متن کاملBruton tyrosine kinase inhibition is a novel therapeutic strategy targeting tumor in the bone marrow microenvironment in multiple myeloma.
Bruton tyrosine kinase (Btk) has a well-defined role in B-cell development, whereas its expression in osteoclasts (OCs) further suggests a role in osteoclastogenesis. Here we investigated effects of PCI-32765, an oral and selective Btk inhibitor, on osteoclastogenesis as well as on multiple myeloma (MM) growth within the BM microenvironment. PCI-32765 blocked RANKL/M-CSF-induced phosphorylation...
متن کاملIn vitro Effect of Pomalidomide on Bone Marrow Mononuclear Cells from Multiple Myeloma Patients
Background: Many features of anticancer drugs, including cytotoxicity and/or cytokine induction, are studied using cell lines orhuman blood leukocytes. However, in a disease such as multiple myeloma, most cancerous cells are resided within bone marrowmononuclear cells. In the present study, we investigated the effect of pomalidomide on apoptosis and IL-2 production of bonemarrow mononuclear cel...
متن کاملThe AKT kinase is activated in multiple myeloma tumor cells.
Immunohistochemistry (IHC) was performed on archived bone marrow (BM) with a phosphospecific anti-AKT antibody. IHC on 26 BM biopsies from patients with multiple myeloma (MM) demonstrated phospho-AKT staining of malignant plasma cells in a cell membrane-specific pattern, whereas nonmalignant hematopoietic cells did not stain. Preabsorption of the antibody with phosphorylated AKT peptide, but no...
