Do morphologic and cytogenetic variables affect the flow cytometric recovery of plasma cell myeloma cells in bone marrow aspirates?
Similar to prior reports, the greatest loss of PC in BM evaluation occurs between the aspirate and postlysis specimens; however, a small amount occurs from further processing. Additional morphologic and cytogenetic factors also appear to influence recovery in addition to overall PC%.
These preliminary findings suggest that the ApoE epsilon4 allele is not strongly associated with a particular pattern of cognitive functioning in African Americans once they are diagnosed with AD. However, these findings require replication in a large prospectively recruited and population-based sample of African American AD patients before firm conclusions can be reached.
