CEBPZ and acute myeloid leukemia: To investigate whether this polymorphism has any prognostic impact in CBF-AML, we assessed the frequency of complete response (CR), event free-survival (EFS) and overall survival (OS) according to the miR-29 polymorphism status in a subset of de novo inv(16) (n = 126) and t(8;21) (n = 100) AML patients treated with intensive cytarabine/-anthracycline-based first-line therapy on CALGB/Alliance trials and whose clinical follow-up information was available.
