High levels of acute phase reactants can be associated with adverse outcome in patients with various solid tumor types. For patients with acute myeloid leukemia (AML), this correlation is unknown. We retrospectively investigated the prognostic value of pretreatment acute phase protein levels in 282 consecutive newly diagnosed AML patients undergoing at least one cycle of intensive induction chemotherapy. We applied a new score integrating pre-treatment C-reactive protein (CRP), fibrinogen, and albumin levels termed the CFA ratio, and we stratified patients into two groups: Patients with a CFA ratio below 3.06 had decisively better progression-free (26.2 vs 7.7 months; P < .001), disease-free (56.4 vs 8.7 months; P < .001), and overall survival (61.2 vs 13.8 months; P < .001).
