Literatür İçeriği : The efficacy of fludarabine in combination with an intermediate dose of cytosine arabinoside, mitoxantrone, and G-CSF (FLANG; fludarabine 30 mg/m(2)/day, cytosine arabinoside 1 g/m(2)/day, mitoxantrone 10 mg/m(2)/day, and G-CSF 300 mug/day for 5 days) was evaluated in patients with refractory or relapsed acute myelogenous leukemia (AML). Between January 2004 and December 2006, 27 patients with relapsed or refractory AML were enrolled in the present study. In total, 14 patients had experienced an early relapse, 10 had experienced a late relapse, and the remaining three (11%) had developed primary refractory leukemia at the time of study entry. Most patients (n = 17, 63%) had post-transplant relapse, and 10 of them relapsed after allogeneic hematopoietic stem cell transplantation (SCT). After FLANG treatment, 15 patients (56%) achieved a complete response (CR), and three patients died during reinduction chemotherapy. After achieving a CR, eight patients received SCT (seven allogeneic (sibling = 4, unrelated = 2, and haploidentical familial = 1) and one autologous SCT), one received donor lymphocyte infusion, three received consolidation chemotherapy, and the remaining three refused further therapy. Eight patients were alive during continuous CR, with an event-free survival (EFS) rate of 30% after a median follow-up of 42.1 months. The survival outcome of patients who received SCT was remarkable (EFS of 75%). Additionally, no toxicity severe enough to preclude transplantation was evident after or during FLANG. The findings of the present study suggest that FLANG salvage chemotherapy is an effective regimen and that it offers a safe bridge to SCT. Furthermore, this regimen prompts efforts to proceed to SCT as post-remission therapy for patients in greater than first CR.
