BACKGROUND We assessed the feasibility of outpatient chemotherapy and supportive care in patients with acute myeloid leukemia (AML). PATIENTS AND METHODS All patients receiving curative intent chemotherapy between 09/01 and 10/02 and meeting our criteria received supportive care post induction chemotherapy as well as their entire consolidation(More)
To develop a purification strategy for isolating the most primitive hematopoietic stem cells present in normal human marrow we have combined cell separation techniques with an assay for cells that initiate sustained hematopoiesis in vitro in the presence of irradiated human marrow adherent cells. These "feeders" were established by subculturing 2- to(More)
Notch transmembrane receptors are known to play a critical role in cell-fate decisions, with Notch1 shown to enhance self-renewal of hematopoietic stem cells and cause T-cell leukemia. Four Notch receptors exist, and the extent of redundancy and overlap in their function is unknown. Notch4 is structurally distinct from Notch1 through Notch3 and has not been(More)
BACKGROUND New treatment options are needed for patients with multiple myeloma that is refractory to proteasome inhibitors and immunomodulatory drugs. We assessed daratumumab, a novel CD38-targeted monoclonal antibody, in patients with refractory multiple myeloma. METHODS In this open-label, multicentre, phase 2 trial done in Canada, Spain, and the USA,(More)
We have found that the small population of cells in human marrow that are characterized by their expression of CD34 can be readily subdivided into two apparently nonoverlapping subpopulations of approximate equal size, one expressing CD45RO and one CD45R. Functional studies of these subpopulations revealed that all of the primitive erythroid colony-forming(More)
Allogeneic bone marrow transplantation (BMT) is the only curative therapy available for patients with myelodysplastic syndrome (MDS). In an attempt to identify prognostic factors influencing outcome, we collected data retrospectively on 60 consecutive adult patients who had undergone BMT at our center for primary MDS or acute myelogenous leukemia evolving(More)
Despite the usual uniform and primitive appearance of cells derived from the leukemic clone in most patients with acute myeloid leukemia (AML), there is considerable heterogeneity among leukemic blasts, particularly with respect to their capacity to proliferate and/or self renew. We have assessed whether these differences in proliferative potential are(More)
Randomized controlled trials have shown a reduction in platelet alloimmunization and refractoriness in patients with acute leukemia (AL) with the use of poststorage leukoreduction of blood products. Universal prestorage leukoreduction (ULR) of red cell and platelet products has been performed in Canada since August 1999. We conducted a retrospective(More)
BACKGROUND Controversy exists regarding the role of high-dose therapy followed by stem-cell transplant (SCT) in the treatment of T-cell lymphoblastic lymphoma (T-LBL). We conducted an intention-to-treat analysis of the strategy of SCT as definitive treatment of T-LBL. PATIENTS AND METHODS From July 1987 to March 2005, 34 adults with T-LBL were diagnosed(More)
Twenty-one patients with poor prognosis nonseminomatous germ cell tumours (six with extreme burden disease at presentation in whom partial remission had been achieved with initial induction therapy, and 15 with recurrent disease after induction therapy) were treated with high-dose chemotherapy and autologous bone marrow transplantation (BMT). The first six(More)
