Sequential Therapy with Fitcy Preparative Regimen for Patients with Primary Refractory AML - a Single Center Retrospective Analysis

Introduction - primary refractory AML is associated with a dismal prognosis. Only 30% of patients will respond to salvage chemotherapy and continue to allogeneic hematopoietic cell transplantation (HCT) with a 10-20% long- term overall survival. Following from the FLAMSA protocol, we implemented a modified RIC regimen - FITCy (fludarabine, cytarabine +/- idarubicin and 4 Gy TBI) in all primary refractory patients with a donor available for transplant.
