[Therapeutic results in acute myelogenous leukemia in the years from 1970 to 1982].

In a retrospective study, three groups of patients with acute myeloid leukaemia were analyzed in respect to the outcome of remission induction therapy: group I (vincristine, daunorubicin and prednisone) was treated between 1970 and 1976, group II (daunorubicin and cytosine-arabinoside) between 1976 and 1980 and group III (daunorubicin, cytosine-arabinoside, 6-thioguanine and consolidation therapy with cyclophosphamide, vincristine, cytosine-arabinoside and prednisone) between 1980 and 1982. Complete remissions were achieved in 49% (group I), 46% (group II) and 65% (group III) of the patients (p greater than 0.05, chi-square test). The mortality rate of the remission induction therapy was significantly reduced from 27% in group I to 15% and 13% in group II and III, respectively (p less than 0.05, chi-square test). The median remission duration increased significantly from four months (group I) to nine months (group III) (p less than 0.05, log-rank test). The long term results were about the same in the three groups. After three years, the proportion of patients being still in first remission was less than 10% in group I and II 13% in group III.
