Treatment of Acute Myelogenous Leukemia With Busulfan and Etoposide Followed by Autologous or Syngeneic Stem Cell Rescue and Low-Dose Interleukin 2 (IL-2) Immunotherapy

Study start date: October 13, 1998

Inclusion Criteria: The patient must have AML that falls into one of the following categories: AML in 1st complete remission (CR) with intermediate or high risk of relapse following conventional therapy; at least, one of the following features is needed: Patient required more than one cycle of induction to achieve first CR White blood cell count (WBC) > 100,000/mm^3 at diagnosis Any of the following cytogenetic abnormalities: inv (3), t(3:3), del (5q) or -5, 11q23, del(7q) or -7, del (20q) or -20, abnormal 12p, +11 or t8 Any other abnormalities or combination of abnormalities which would predict intermediate or high risk of relapse AML beyond first CR Any patient with an identical twin donor who also meets the criteria above Patients with AML in 1st CR should receive at least two cycles of consolidation chemotherapy prior to mobilization and transplant Patients must have an adequate number of stem cells previously collected (i.e., > 2 x 10^8 total nucleated cell [TNC] of bone marrow [BM]/kg or 4 x 10^6 [CD]34+ PBSC/kg, unless approved otherwise by Dr. Holmberg); prior to stem cell collection patients must be documented to be in remission and to have received two cycles of consolidation therapy after induction therapy Pre-Study tests have been performed Patient must sign an institutional review board (IRB) approved informed consent, conforming with federal and institutional guidelines Exclusion Criteria: Patients with good risk AML defined by cytogenetic evaluation with these abnormalities: inversion 16 or t8;21 Patient's life expectancy is severely limited by diseases other than AML Patient is human immunodeficiency virus (HIV) seropositive Patient is pregnant Patient's creatinine > 2.0 mg/dl Patient's total bilirubin > 2.0 mg/dl (unless Gilbert's disease) Or serum glutamic oxaloacetic transaminase (SGOT)/serum glutamic pyruvic transaminase (SGPT) >= 2.5 x upper limit of normal (ULN) not due to leukemia Patient has a history of congestive heart failure, uncontrolled arrhythmias or left ventricular ejection fraction (LVEF) < 50% Patient has an unrelated human leukocyte antigen (HLA) matched donor and is eligible for a higher priority Fred Hutchinson Cancer Research Center (FHCRC) protocol (for FHCRC patients only) Patient has an HLA matched or one antigen mismatch family donor available Patients with a significant active infection that precludes transplant Patients with a Karnofsky Performance Score less than 70
