Bone marrow versus peripheral blood: comparison of the chimerism analysis
Original language description
Background Bone marrow (BM) examination is routinely performed for minimal residual disease monitoring in leukemia patients. By contrast, chimerism is usually tested from peripheral blood (PB), and, surprisingly, little is known about the clinical impactof the chimerism status in BM. Patients and Methods 226 pairs of PB and BM samples obtained from 102 adult patients were investigated. Frequencies of diagnoses within samples were as follows: AML 42%, CML 24%, ALL 11%, CLL 7%, MDS 7%, other hematological malignancies 9%. Assessment of chimerism was performed using either capillary electrophoresis with fluorescence detection, or quantitative real-time PCR with one order of magnitude higher sensitivity of mixed chimerism detection. Results Mixed chimerism in BM was detected even more than 9 years after transplantation, however, on the other hand, complete donor chimerism was also observed as early as day +35.
