ABSTRACT
<p><b>OBJECTIVE</b>To investigate the relationship between the biological features and the treatment efficacy and prognosis in acute myeloid leukemia subtype M2 (AML-M2) patients with chromosome 8 and 21 translocation.</p><p><b>METHODS</b>By using Cox regression model and Kaplan-Meier analyses, prognostic factors in 54 cases of de novo adult AML with t(8;21) in our institute from 1990 to 2003 were retrospectively analyzed.</p><p><b>RESULT</b>The complete remission (CR) rates were 81.9% for all M2 patients, 82.4% for patients with normal karyotype, 88.5% for patients with t(8;21) [P > 0.05 for normal karyotype vs t(8;21)], 100.0% for 28 patients with t(8;21) alone and 75.0% for 24 patients with additional chromosome abnormalities (P < 0.01). The actuarial 3 year overall survival(OS) was 26% for M2 patients with normal karyotype, 25% for patients with t(8;21) [P > 0.05 for normal karyotype vs t(8;21)], in whole t(8;21) group, 46.4% for patients with t(8;21) alone and 0% for patients with additional chromosome abnormalities (P < 0.01). Multivariate analysis of prognostic factors showed that chromosome abnormalities besides t(8;21) was the only factor affecting CR, disease-free survival (DFS) and OS. DFS of allogeneic hematopoietic stem cell transplantation (HSCT) and intermediate-dose cytarabine/high dose cytarabine (IDAC) groups were better than the group received routine dose cytarabine as postremission therapy (P < 0.01).</p><p><b>CONCLUSION</b>AML with t(8;21) is not a single defined AML subset, and patients with additional chromosome abnormalities have a worse prognosis. HSCT and IDAC could improve the outcome. HSCT is the best choice for patients with high risks, especially with additional chromosome abnormalities.</p>
