CD56 Expression Is an Indicator of Poor Clinical Outcome in Patients With Acute Promyelocytic Leukemia Treated With Simultaneous All-Trans-Retinoic Acid and Chemotherapy

Abstract

The expression of CD56 is significantly associated with inferior CR duration and survival in patients with APL who were treated with modern frontline treatment that included ATRA and simultaneous chemotherapy. Combined with other well-established prognostic factors such as WBC count, CD56 expression at diagnosis might be used to build prognostic scores for risk-adapted therapy in APL.
