Transfusion with blood from a donor with chronic myelogenous leukemia: persistence of the bcr/abl translocation in the recipient

BACKGROUND: Transfusion of cells harvested from patients with chronic myelogenous leukemia (CML) as a therapeutic measure for patients with granulocytopenia was popular in the 1970s, when studies examining the persistence of transfused donor cells were limited by a lack of molecular techniques. Blood samples from a patient who recently received an inadvertent transfusion of CML cells were evaluated for the presence of the bcr/abl translocation characteristic of CML.
