dc.description.abstractThe product of the percentage blasts on the bone marrow aspirate (BMA) and the biopsy cellularity has been tarmed the "absolute blast index aspirate" (ABI-aspirate) and is used to measure disease response on day 7 of induction therapy. The authors compared the event-free survival (EFS) in high-risk and standard-risk patients as identified by the ABI-aspirate and the BMA percentage blasts on day 14 of induction therapy. Both indices identified high-risk cases. EFS of patients categorized as high-risk by these 2 methods and the high-risk criteria used by the authors' service (WCC of > 20 × 109/L, age < 2 and > 8 years and a peripheral blood blast count of > 1.0 × 109/L on day 8 of induction) did not differ. There was concordance between patients identified as high risk by all 3 methods. The results confirmed the prognostic value of the ABI-aspirate and the BMA percentage blasts on day 14 of induction therapy, but these methods were not superior to the high-risk criteria currently in use.
