Bone marrow analysis with cytogenetics (karyotype, with or without fluorescence in situ hybridization [FISH]) is necessary for stratifying and to guide therapy of AML.1

The bone marrow biopsy provides insight into the2:

  • Degree of disease involvement
  • Specific histologic features associated with the leukemic process (eg, necrosis, fibrosis)
