Peripheral blood progenitor cell mobilization with intermediate-dose cyclophosphamide, sequential granulocyte-macrophage-colony-stimulating factor and granulocyte-colony-stimulating factor, and scheduled commencement of leukapheresis in 225 patients undergoing autologous transplantation.

Background: Interpatient variability in the kinetics of peripheral blood progenitor cell (PBPC) mobilization is commonly seen with conventional chemotherapy-based mobilization regimens. This necessitates the availability of leukapheresis (LP) facilities 7 days a week.

Study Design And Methods: The efficacy of an approach where LP was invariably commenced on Day 11 after intermediate-dose cyclophosphamide followed by sequential administration of granulocyte-macrophage-colony-stimulating factor (CSF) and granulocyte-CSF (Cy/GM/G) was retrospectively analyzed in 225 consecutive, unselected patients undergoing autologous hematopoietic stem cell transplantation for all diagnoses other than acute leukemia at our center.

Non-anthracycline based remission induction therapy for newly diagnosed patients with acute myeloid leukemia aged 60 or older.

We assessed remission rates and toxicity in 24 consecutive elderly (age>or=60) patients with untreated Acute myeloid leukemia (AML) who received the anthracycline-free combination of fludarabine, cytosine arabinoside and G-CSF (FLAG) as initial induction chemotherapy at our center. CR was achieved following one cycle of FLAG in 14 patients (58%). Another four patients cleared blasts from their bone marrow by day 30 without complete platelet recovery.
