FLT3 and acute myeloid leukemia: We tried to figure out factors associated with the CD70 expression level on AML blasts, but unfortunately, no significant parameters were identified, including the FAB (French-American-British) classification of AML, chromosome karyotype abnormality [translocation (8; 21), inversion (16), translocation (9; 11)], and specific gene mutations (FLT3-ITD and DNMT3A) (Supplementary Table 3).
