Treatment of relapsed adult acute lymphoblastic leukemia with fludarabine and cytosine arabinoside followed by granulocyte colony-stimulating factor (FLAG-GCSF).
The aim of the present study was to evaluate the efficacy of the combination of fludarabine 30/mg/m2 + cytarabine 2g/m2 followed by the administration of G-CSF to achieve a complete remission (CR) in patients with relapsed acute lymphoblastic leukemia (ALL). We treated twelve patients in first relapse, overall 10 patients achieved a second CR, one patient showed resistant disease and one patient died during remission induction. The regimen was well tolerated and we observed a short period of neutropenia with a low incidence of myelosuppression-associated problems. Eight patients in second CR received the same chemotherapeutic regimen as consolidation used for the reinduction. In six patients the chemotherapeutic regimen was well tolerated, two patients died, (cerebral hemorrhage in one patient and sepsis in the other). In conclusion the combination of fludarabine, cytarabine and G-CSF has significant antileukemic activity and non hematological toxicities were acceptable. The addition of G-CSF reduced the period of neutropenia obtaining a low incidence of myelosuppression-associated problems.
