[Evaluation of the myelogram carried out on the 6th day of remission- inducing treatment of acute nonlymphoblastic leukemia in adults as an indicator of therapeutic effectiveness].

Aspiration biopsy in 31 patients with AML was performed prior to and in the 6th day of induction therapy. Studied group included 17 women and 14 men of 40 yrs mean age. Blastosis prior to and on the 6th day of the observation were compared and the index of blastosis reduction counted. Median value of blastosis reduction was 29.5%, 40% of the patients with the index below the median value showed complete remission, while the patients with the indexes above the median value obtained significantly higher number of complete remission (CR = 81%, p less than 0.05). Statistically significant reduction of leukaemic infiltration in examined myelograms was as s rule the sign of oncoming favourable therapeutic result. In cases of nonaplastic marrow with persistent blastosis (blastosis reduction 29.5%) one should consider a change of the therapeutic regimen.
