Purpose: Important advances in the treatment of acute myelogenous leukemia have
been made with the introduction of cytosine arabinoside(ara-C) and
anthracycline(daunorubicin) over the past 20 years. Currently, 50 to 85% of patients with
acute myelogenous leukemia achieve complete remission with induction chemotherapy
consisting of ara-C and daunorubicin. About 25% of complete responders will have
extended long-term survival and may be cured. Therefore we treated patients having
acute myelogenous leukemia with AD(7+3) regimen and analyzed factors complete
remission rate, remission duration, and survival duration.
Materials and Methods: Induction therapy; Thirty seven patients with previously
untreated acute myelogenous leukemia treated with AD(7+3) regimen(ara-C, 200
mg/m2/d by continuous infusion for seven days, and daunorubicin, 45
mg/m2/d for 3 days). The second course of therapy was AD(5+2), if the
patients failed to enter remission. Consolidation therapy; three cycles of consolidation
chemotherapy were administrated with at least 4 week interval following remission.
Course 1 ; ara-C at 100 mg/m2 by continuous infusion every 12 hour
for five days, 6-thioguanine at 100 mg/m2/day orally for 5 days. Course 2;
ara-C is same as course 1, vincristine at 1.2 mg/m2(maximum 2 mg) by
bolus injection for 1 day, prednisolone at 40 mg/m2(maximum 60 mg)
orally for 5 days. Course 3; ara-C is same as course 1, daunorubicin at 45
mg/m2 by 1 hour infusion for 2 days.
Result: 62.2 percent of the 37 patients entered complete remission. The remission
duration for all patients in complete remission ranged from 2 months to
63+ months, with the median of 15.1 months. The median duration of
survival in complete responder group was 23.3 months. Among various prognostic
factors, females and groups with normal chromosome and t(8;21) or t(15;17) had
significantly higher complete remission rate than males and groups with other
chromosomal abnormalities, respectively. Factors influencing on survival duration were
female, normal chromosome, t(8;21) or t(15;17), Auer rod-positive, and peripheral blast %
less than 50% at diagonosis. Groups with Auer rod-positive, normal chromosome, and
t(8;21) or t(15;17) also had significantly longer remission duration.
Conclusion: Combination chemotherapy with cytosine arabinoside and daunorubicin is a
effective regimen for acute myelogenous leukemia as much as other regimen for acute
myelogenous leukemia. Further clinical trials for effective treatment regimen are
necessary to increase the complete remissioin rate.
