Popis: PURPOSE To investigate the value of intensive consolidation chemotherapy not followed by maintenance therapy in adult acute lymphoblastic leukemia (ALL). MATERIALS AND METHODS A multicenter phase II trial was conducted in 130 adult patients with ALL between 16 and 60 years of age. After standard induction therapy, postinduction chemotherapy was given: three courses of high-dose cytarabine (2,000 mg/m2 every 12 hours for four doses) in combination with amsacrine (course one), mitoxantrone (course two), and etoposide (course three). CNS prophylaxis consisted of 10 injections of intrathecal methotrexate (IT MTX). Patients younger than 50 years with an HLA-identical sibling were eligible to receive allogeneic bone marrow transplantation (BMT). RESULTS Ninety-five patients (73%) achieved complete remission (CR); 82% were younger than 50 years and 41% were older than 50 years. Seventeen patients (13%) were resistant to chemotherapy, and 18 (14%) died during induction treatment. Only age and performance status were significantly associated with response (PCONCLUSION Intensive consolidation including high-dose cytarabine not followed by maintenance therapy provides an outcome for adult patients with ALL that may be worse or even inferior compared with studies using long-term maintenance therapy. High-dose cytarabine in combination with IT MTX was effective for CNS prophylaxis.
