A 74-year-old man was admitted on November 1986 because of general fatigue. His peripheral blood showed pancytopenia without immature cells since December 1985. Hematological data showed RBC 150 X 10(4)/microliter, PLT 7,000/microliter, WBC 12,000/microliter with 93.6% leukemic cells. The bone marrow smear revealed NCC 14.5 x 10(4)/microliter with 76% leukemic cells. The leukemic cells were characterized by faint staining with peroxidase stain and strong positivity for CD 13 antigen determined with immunoperoxidase method and flow cytometric analysis. The chromosomal analysis of tumor cells represented as follows: 44, XY, -3, -4, -9, -20, 2q+, 6p-, 7q-, 12q+, +2 mar. Although remarkable reduction of leukemic cells in peripheral blood was obtained one month after initiation of 19-days intravenous continuous infusion of N4-behenoyl-1-beta-D-arabinofuranosylcytosine (BHAC), he suffered from severe systemic candida infection with severe leukopenia and died. Not only advanced age but also complex karyotypic abnormality would contribute to failure of treatment in this case. The significance of complex karyotypic abnormality in acute non-lymphocytic leukemia in discussed based on the current literature.
