Acute myelogenous leukemia in a donor after granulocyte colony-stimulating factor-primed peripheral blood stem cell harvest.

摘要

This article describes the first case of acute myeloid leukemia (AML) in a healthy donor at 14 months after granulocyte colony-stimulating factor (G-CSF)-primed peripheral blood stem cell (PBSC) harvest. In September 2001, a healthy 61-year-old female was given G-CSF prior to PBSC harvest for her brother with multiple myeloma. In spite of successful engraftment, the recipient died from a disease relapse. In November 2002, the donor, admitted with high fever and leukocytosis with 98.5% blastoid cells, was diagnosed as having AML (M1). Her leukemia cells were positive for CD13, CD33, and G-CSF receptor without chromosomal abnormality and responded to G-CSF in vitro. During chemotherapy, she died of progressive pneumonia. If our case is truly the first, the incidence of leukemia in donors may not be higher than that of naturally occurring leukemia. However, efforts towards an international long-term study, or at least to report every case similar to ours, would be required to be conclusive.
