ABSTRACT
The purpose of this study is to know the disease-free survival in children with acute lymphoblastic leukemia (ALL), submitted to two therapeutic programs. Habitual risk was defined as age older than 2 and younger than 10 years, without neurological, mediastinal or testicular infiltrations, leukocytes < 25 x 10(9)/l and morphologic cell type distinct of L-3. The first group (LAL81) included 30 patients, from 1981 to 1986, and they received induction with vincristine (VCR) and prednisone (PDN); consolidation with mercaptopurine (MP), cytosine arabinoside (ARA) and doxorubicin (DOX); prophylaxis to the central nervous system (CNS) with radiotherapy and methotrexate (MTX)-ARA-hydrocortisone (HDR) intrathecal, and maintenance with MP and MTX. In the second group (LAL87), 28 patients were included from 1987 to 1993. They received induction with VCR, PDN and lasparaginase (ASP); consolidation with MP, ARA, DOX, carmustine (BCNU) and cyclophosphamide (CFA); prophylaxis to the (CNS) with intrathecal MTX-ARA-HDR, and maintenance with MP and MTX. There was just one therapeutic failure. In the LAL81, protocol 11 relapses and 9 in LAL87 (p = 0.71) were observed. Of these, two in each group went to the CNS. The disease-free survival in LAL81 was 0.39 at 14 years; in LAL87, was 0.53 at 8 years (p = 0.62).
