CRP and chronic myelogenous leukemia, BCR-ABL1 positive: Similar to cyclic oscillations in leukocyte (neutrophil) counts reported in patients with CML [21,22], cyclic oscillations in basophil counts with simultaneous elevations in CRP levels and association with febrile episodes were only demonstrated by Cehreli et al. [5] in patients with primary CBL [4], but not reported in patients with primary [3] and secondary CBL [6,7,8,9].
