This study aims to evaluate the prognostic value of reclassifying acute leukemia based on in vitro growth characteristics.
Conducted agar culture analysis of marrow and blood from 127 cases of acute leukemia.
Grouped patients by in vitro growth parameters, including buoyant density and plating efficiency of leukemic cells.
Calculated remission rates based on growth patterns and conventional hematologic parameters.
Patients with a favorable growth pattern had a remission rate of 52%, while those with poor growth patterns had a 10% remission rate.
Age significantly influenced remission rates, with 91% remission in patients under 40 years in the favorable prognosis group.
In vitro growth type demonstrated highly significant differences in remission probability across the different patterns.
