[Acute lymphoblastic leukemias off therapy: course of 80 cases after treatment cessation].

Purpose: To retrospectively analyse all the patients diagnosed and treated in the same hospital for acute lymphoblastic leukaemia (ALL) in whom therapy was suppressed after sustained complete remission (CR) for a variable period.

Patients And Methods: Eighty cases of ALL treated at the Jiménez Díaz Foundation between 1968 and 1991 were revised. Treatment had been suppressed after 60 months of maintained CR (1968-1974) or after 28 months (1986-1991), with a median follow-up after suppression of 6 years.
