This is quite surprising because the blood serum levels of HGF have been reported to be abnormal in myeloma, acute myeloid leukaemia (AML), chronic myelogenous leukaemia (CML) andmyeloproliferative neoplasms (MPNs) [12,13,14,15]. Here, HGF is linked to chronic myelogenous leukemia, BCR-ABL1 positive.
