Thirty elderly (> 60 years) Philadelphia chromosomepositive (Ph+) patients with acute lymphoblastic leukemia (ALL) received imatinib, 800 mg daily, associated to steroids without further chemotherapy as frontline treatment. Median age was 69 years (range, 61-83 years). Twenty-nine patients were evaluable for response and all of them obtained a hematologic complete remission, with a median BCR-ABL reduction of 2.9 and 2.0 logs in p190+ and p210+ cases, respectively. Most of the induction treatment did not require admission of the patients. No major toxicities occurred and the treatment was well tolerated. Median survival from diagnosis was 20 months. This study shows that elderly Ph+ patients with ALLoften considered eligible only for palliative treatment strategiesmay benefit from an imatinib-steroids protocol, which does not require chemotherapy nor a long hospitalization, is feasible, highly active, and associated with a good quality of life.
