POG 9061 protocol to treat isolated central nervous system recurrence in patients with acute lymphoid leukemia at Hospital Universitario de Santander. Rev. Univ. Ind. Santander.

Introduction: Acute lymphoblastic leukemia (ALL) is the most frequent neoplasm in children. Relapses to central nervous system (CNS) Appears in 5-10 % of the ALL patients and is a bad prognostic factor. Objective: To describe the results obtained with modified POG 9061 protocol in a pediatric oncology unit. Methodology: Survival analysis was made and main complications caused by protocol were analyzed in a retrospective cohort with all of patients attended for ALL with isolated relapse to CNS. Results: Fifteen patients attended from 1993 to 2007 were included; 66.6 % CNS relapses were early to 18 mounts following ALL remission. Two patients left protocol, with one death; there were another two deaths among other patients. Five year global survival rate was 85.6 % (95 %CI 53.3-96.2 %), and event-free survival rate was 84.9 % (95 %CI 51.2-96.0 %). The most frequent complication was mielosupression; renal function alteration was not observed, with a light elevation of hepatic function tests. Infection was the main hospitalization cause. Conclusions: Survival rates and complications (type and frequency) are similar to the other studies. This finding is relevant because half of the patients had early CNS relapse after ALL remission.
