Hematopoietic cell transplantation (HCT) is the IV infusion of hematopoietic stem and progenitor cells designed to establish marrow and immune function in patients with a variety of acquired and inherited malignant and nonmalignant disorders. More »
Multiple myeloma is a disseminated malignancy of monoclonal plasma cells that accounts for 15% of all hematologic cancers. In 2010, an estimated 20,180 new cases will be diagnosed in the United States, and 10,650 Americans will die of this disease. More »
Multiple myeloma (MM) remains incurable despite the current approaches used in initial therapy, including more effective induction therapy, one or more autologous stem-cell transplants, and consolidation/maintenance strategies. More »
Multiple myeloma (MM) is a malignant, progressive plasma cell tumor characterized by overproduction of monoclonal immunoglobulins, osteolytic bone lesions, renal disease, and immunodeficiency.[1] Before the 1980s, patients with MM experienced a slow, progressive decline in quality of life until death approximately 2 years after diagnosis.

Exposure of live cells to shear flow induces major changes in cell shape, adhesion to the extracellular matrix, and migration. In the present study, we show that exposure of cultured multiplemyeloma (MM) cells to shear flow of 4-36dynes/cm(2) triggers the extension of long tubular protrusions (denoted flow-induced protrusions, or FLIPs) in the direction of the flow. These FLIPs were found to be rich in actin, contain few or no microtubules and, apart from endoplasmic reticulum (ER)-like membranal structures, are devoid of organelles. Studying the dynamics of this process revealed that FLIPs elongate at their tips in a shear force-dependent manner, and retract at their bases. Examination of this force dependence revealed considerable heterogeneity in the mechanosensitivity of individual cells, most likely reflecting the diversity of the malignant B cell population. The mechanisms underlying FLIP formation following mechanical perturbation, and their relevance to the cellular
Patients with multiplemyeloma undergoing autologous haemopoietic stem cell transplantation (ASCT) are at high risk for infectious complications. Peri-transplant intravenous immunoglobulin (IVIG) has been used with the aim of reducing these risks. Our retrospective, non-randomised study of peri-transplant IVIG use and effect on infectious complications in 266 ASCTs for myeloma from 2000 to 2009 at a major metropolitan referral centre for haematological malignancies found no difference between those receiving peri-transplant IVIG (0.4 g/kg) (n=130) and those who were not (n=110) with regard to bloodstream infections, pneumonia, urinary tract or gastrointestinal infections. When analysed according to pre-transplant therapy (conventional chemotherapy versus novel agents), there was no significant difference in infectious complications between those who did or did not receive peri-transplant IVIG. In conclusion, our study did not show a benefit for the use of peri-transplant IVIG (0.4 g/kg
