The optimal protocol for mobilization of hematopoietic stem cells in patients with lymphoid malignancies has not been determined so far. We retrospectively analyzed the efficacy and safety of Ara-C at a dose of 1.6 g/m(2) compared with CY at a dose of 4.0 g/m(2), both combined with filgrastim. Seventy and forty-five patients, respectively, were included, among whom 60% were defined as 'predicted poor mobilizers'. The use of Ara-C was associated with significantly higher peak number of circulating CD34(+) cells compared with CY (P<0.0001). In the Ara-C group, 95% of patients with multiple myeloma (MM) collected at least 5 × 10(6) CD34(+) cells/kg required for tandem transplantation, and 97% of lymphoma patients collected at least 2 × 10(6) CD34(+) cells/kg, needed for a single autologous hematopoietic SCT (autoHSCT), which was achieved with a single leukapheresis in 91% of cases. Results for the CY group were significantly inferior (P<0.0001). No patient mobilized with Ara-C experienced febrile neutropenia, whereas 35% required platelet transfusions. Among patients who proceeded to autoHSCT, the time of both neutrophil and platelet recovery was significantly shorter for those mobilized with Ara-C than CY. We conclude that intermediate-dose Ara-C+filgrastim is a very effective and relatively safe mobilization protocol for patients with lymphoid malignancies.Bone Marrow Transplantation advance online publication, 7 January 2013; doi:10.1038/bmt.2012.269.
