RESUMO
PURPOSE: This prospective phase II, open label, study was designed to assess the efficacy and safety of D-CAG induction treatment for elderly patients with newly diagnosed AML. EXPERIMENTAL DESIGN: All patients in this study were treated with decitabine of 15 mg/m2 for 5 days and G-CSF for priming, in combination with cytarabine of 10-mg/m2 q12h for 7 days and aclarubicin of 10 mg/day for 4 days (D-CAG). RESULTS: Among 85 evaluable patients, overall response rate (ORR) and complete remission (CR) were 82.4% and 64.7%, respectively, after 1 cycle of therapy. The ORR in patients aged <70 years was 83.0% and 81.6% in patients aged ≥70 years. There was a significantly longer median overall survival (OS) in patients with response (16 months) than in those without response (7 months, p< 0.0001). The OS for patients aged ≥70 years and 60-69 years was 10 months and 12 months, respectively (p=0.4994). The two-year OS probability was 19.2% and the twenty-month survival rate was 33.8%. Induction mortality of D-CAG treated elderly patients with AML is 4.4%. CONCLUSION: D-CAG regimen was well tolerated and showed a promising clinic efficacy in elderly patients with AML (≥70 years).
