[Acute lymphoblastic leukemia in infants--results of treatment according to infant leukemia protocol--POG 8493]

Abstract

Analysis was made of ALL treatment results according program POG 8493 in 9 infants. In 4 children WBC exceeded 100.0 G/l, and in 5 children CNS was affected. Eight infants had remission, six had relapse (mainly BM): early up to 8 month in 5, late--in 52 month in one girl. Four children died after relapse, four are still living: 2 I RC (2 and 23 months), 2 in II RC (1 month and 23 month). Probability of 4-year EFS was 0.25 and that survival--0.44. In view of continuing poor ALL prognosis, in infants it is necessary to look for more effective methods of treatment.
