BACKGROUND AND OBJECTIVE: Several groups have used salvage chemotherapy in relapsed or refractory lymphomas to mobilize peripheral blood stem cells. The objective of this study was to evaluate the antilymphomatous efficacy, the ability of mobilization and the toxicity of a regimen containing high-dose ifosfamide, etoposide, methylprednisolone (IFOVM) and granulocyte colony-stimulating factor (G-CSF). PATIENTS AND METHOD: Twenty-four patients with relapsed or refractory lymphoma received IFOVM and G-CSF. The median age was 45 years and 13 were males. The histologyc subtypes of lymphoma were: diffuse large B cell (DLBCL) (n = 15), Hodgkin (n = 2), Burkitt (n = 2), mantle cell (n = 2), anaplastic (n = 1), peripheral T-cell (n = 1) and follicular (n = 1). RESULTS: Two patients died of sepsis within the pancytopenia period. In 17 (77%) of the remaining patients more than 1.5 × 106 CD34+ cells/kg (median: 7.7 × 106 CD34+ cells/kg) were collected. The median time to peripheral blood stem cells harvest was 17 (range: 13-24) days and 4 patients required 2 procedures of apheresis. Sixteen patients (67%) developed neutropenic fever. The median time to achieve granulocyte cell count ≥ 1 × 109/l and platelet count ≥ 20 × 10 9/l was 15 and 16 days, respectively. The only factor predicting successful mobilization was the diagnosis of DLBCL (p = 0.04). Ten patients underwent peripheral blood stem cells transplantation. CONCLUSIONS: The regimen IFOVM and G-CSF allows an effective peripheral blood stem cells mobilization in patients with lymphoma, particularly in those with DLBCL, but it is associated with significant toxicity.
