    Abstract:
    The prognostic value of cellular DNA content measured by static cytophotometry was evaluated in 69 children with acute lymphoblastic leukemia (ALL) using the pretreatment distribution of the DNA content in blast cells of bone marrow and peripheral blood. The median follow-up of the whole group of patients was 45 months. Aneuploidy was detected in 71% of children, most of them showing a hyperdiploid content (DNA index greater than 1.05). The duration of complete remission was significantly longer in patients with distinct hyperdiploid DNA content (DNA index greater than 1.16) than in those with less hyperdiploid and diploid DNA content (DNA index less than 1.16). The results achieved by static cytophotometry were compared with flow cytometry analysis and with cytogenetic investigations of chromosomal abnormalities in leukemic cells. Higher correlation was found between flow cytometry and cytogenetics. Flow cytometry proved to be a more convenient method for detection of the DNA content in leukemic cells than static cytophotometry.
