K. Usuki et al., COMBINATION THERAPY WITH GRANULOCYTE-COLONY-STIMULATING FACTOR, ALL-TRANS-RETINOIC ACID, AND LOW-DOSE CYTOTOXIC DRUGS FOR ACUTE MYELOGENOUSLEUKEMIA, Internal medicine, 34(12), 1995, pp. 1186-1189
A 67-year-old man presented with acute myelogenous leukemia (M2), Peri
pheral blood examination revealed a leukocyte count of 1,700/mu l with
1% myeloblasts, and bone marrow aspiration showed 42.6% myeloblasts w
ith Auer bodies, Culture of his marrow cells at diagnosis showed that
granulocyte colony-stimulating factor (G-CSF) promoted cell proliferat
ion, while all-trans retinoic acid (ATRA) inhibited the proliferative
effect of G-CSF and induced differentiation. Combination therapy with
G-CSF, ATRA, and low-dose cytotoxic drugs achieved complete remission
without severe marrow suppression.
