Results Of High Dose Chemotherapy And Autologous Stem Cell Transplantation In Patients With Acute Myeloid Leukemia.

35 patients with acute myeloid leukemia have undergone transplantation at our institution over the past 12 years. Patient selection criteria included age less than 70 years, creatinine less than 2mg/ml, no active infection, cardiac ejection fraction >40%, DLCO > 50% of predicted and no other co-morbid conditions that would jeopardize survival. 31 patients were in first remission, 4 were in second or higher remission. 3 patients had favorable cytogenetics, 25 had intermediate or unfavorable cytogenetics. After achieving remission for at least 30 days, patients were consolidated with Etoposide and AraC, followed by G-CSF. Hematopoietic stem cells were collected when the WBC rebounded to at least 10,000/ml. The target dose of CD34 positive cells was 5x106/kg. The minimum dose given was 2.3 x 106/kg). The average age at transplantation was 41 years (range 22 to 61). Days of neutropenia (AGC<500/ml) ranged from 2 to 10 (average 5.1). The median length of follow up is 2.6 years. Currently 26 patients are alive, and 25 are free from progression. Overall survival is 63%, and progression-free survival is 47% at both 5 and ten years.
