[Use of alpha interferon preparations in acute lymphoblastic leukemia in children during remission].

The Soviet alpha-interferon drugs (human leukocytic interferon, reaferon) were used in the program of the treatment of children with acute lymphoblastic leukemia (during remission). The treatment was found to be more effective with an increase of its duration, relapse-free course of the disease (69.4-82.3%) and survival (70.1-93.1%) of patients with an unfavourable disease prognosis (over 5 years).
