Abstract

Background Acute lymphoblastic leukemia (ALL) in children has
high cure rate but it can cause death due to the side effects of
treatment or to the disease itself. Thus the evaluation on response
of treatment is important and may predict the prognosis. Since
apoptosis can be induced by chemotherapy, it is thought that the
number of leukemic cells that undergo apoptosis may reflect drug
sensitivity and cytoreduction rate, thus it may correlate with prog-
nosis.
Objective To detect apoptotic cells in peripheral blood of children
with ALL during the first week of treatment.
Methods We conducted a cross sectional study on 58 children
with newly diagnosed ALL treated in Department of Child Health,
Sardjito Hospital, Yogyakarta. Apoptotic cells were detected on
smears of buffy coat made from peripheral blod and stained with
May-Grunwald Giemsa. The apoptotic cells viewed under light mi-
croscope within 12 time points during 7 days after treatment started.
Results Apoptotic cells were identified in 3 of 58 patients with
index range of 4.2% to 36.2%.
Conclusion Apoptotic cells can be detected in peripheral blood
with simple method. The explanation of why not all blood smears
viewed showed these cells need further study. It may due to the
methods or the apoptotic process itself.
