Abstract
Sixty-two adult patients with acute myeloid leukemia were treated with a chemotherapy program of Adriamycin, Cytosine Arabinoside (Ara-C), vincristine, and prednisone (Ad-OAP). Immunotherapy with BCG by scarification was administered before and/or during remission induction therapy. Maintenance chemoimmunotherapy consisted of Ara-C, vincristine, prednisone, and BCG. Patients still in remission after 12 months received late intensification chemotherapy for three courses before discontinuing chemotherapy. Forty-four (71%) patients achieved a complete remission (CR). The CR rate for patients less than 50 years of age was 84% (32/38). Age was strongly predictive for response and survival. An additional 14 patients with acute lymphoid leukemia were treated with the same program; ten patients responded, all have relapsed and died. Nine patients with AML remain alive 41/2–6+ years from diagnosis.
