ABSTRACT
<p><b>OBJECTIVE</b>To investigate the therapeutic effectiveness and side effects of decitabine combined with or without cytarabine-based low dose regimen for acute myeloid leukemia in geratic patients.</p><p><b>METHODS</b>Clinical data of 8 geratic patients (aged over 70 years) suffered from acute myeloid leukemia from September 2009 to March 2012 were analyzed retrospectively, including age, sex, peripheral blood and bone marrow characteristics and so on. These patients were treated by an 1-hour intravenous infusion of decitabine 20 mg/mper day for 5 consecutive days every 4 weeks combined with or without low dose regimen dominantly consisting of cytarabine 20 mg per day as subcutaneous injection for seven consecutive days. The therapeutic effectiveness and side-effects were evaluated.</p><p><b>RESULTS</b>Among 8 patients, incinding 3 males and 5 females aged between 71-84 years old, their median white blood cell count was 31.2(1.38-179)× 10/L, and median bone marrow blast cell ratio was 42.7(23-94)% at the initial diagnosis.The median treatment courses was 2.5 (1-20).After treatment by this protocol,2 patients achieved complete remission(CR) (25%), 2 patients achieved partial remission (PR)(25%), 3 were not relieved, and 1 died, thus the overall response rate reached to 50% (4/8). The median overall survival time was 9.5 (2-36) months, and the overall survival time of 3 patients reached 1 year or more. The main side-effects of treatment were grade III-IV of myelosuppression (87.5%) and pneumonia (50%).</p><p><b>CONCLUSION</b>Decitabine combined with or without cytarabine-based low dose regimen is promising for the treatment of geriatric acute myeloid leukemia, thus improving the overall response rate, and prolonging overall survival time.</p>
