[Liposomal daunorubicin and interferon-alfa in combination with all-retinoic acid--a new regime for the treatment of acute promyelocytic leukemia].
OBJECTIVE
To define duration and schemes of maintenance therapy, to evaluate cytarabine demand while treatment of acute promyelocytic leukemia (APL) with an original program 5D + Ifa + AT RA.


METHODS
The above treatment was conducted in 7 patients with APL (1 male, 6 females, 18-45 years, leukocytes 1.2-15.0 x 10(9)/l).


RESULTS
Induction by 5D program was performed in 5 patients. A complete remission was achieved in 4 of them, molecular--in 3. One woman died. 5D consolidation was performed in 6 patients. After the first course of consolidation all the patients achieved molecular remission. Maintenance of remission with Ifa + ATRA was made in 5 patients. In one female the remission came to the end. Mean time of the follow-up was 18 months. The remission lasted 5-36 months. Monitoring of molecular remission has not found marker PML/RARa.


CONCLUSIONS
Daunozom monotherapy leads to a complete remission after the first course in most of the patients. In the majority of them it was molecular. Maintenance with If + ATRA for 2 years maintains molecular remission for 5-36 months.
