Incidence and Characteristics of Central Nervous System Involvement in Adult Acute Myeloid Leukemia Patients

Features of central nervous system (CNS) involvement in acute myeloid leukemia (AML) are not well-defined. Unlike acute lymphoblastic leukemia, there are limited guidelines for the use of intrathecal chemotherapy with induction for AML, and institutional practices vary. Unfortunately, AML patients with CNS involvement often have worse outcomes compared to those without CNS involvement (Del Principe et al., 2018; Rozovski et al., 2015). It is important to better understand the incidence and predictive clinical and features of CNS involvement in AML to identify patients for diagnostic testing and intrathecal chemotherapy. This retrospective analysis evaluated the incidence and characteristics of CNS involvement in adult AML patients at our institution.
