A feasible shortcut for the mobilization outcome: Steady state CD34 positive hematopoietic stem cells

Predicting success of hematopoietic cell mobilization is an important issue for transplant physicians. We examined the steady state peripheral blood CD34+ cell count to predict ability to mobilize adequate hematopoietic progenitor cells in 63 myeloma and lymphoma patients. The median steady state CD34+ cell number was 1.56/μL (0.03-5.76). Although counting steady state CD34+ is definitely cost effective to predict the successful mobilization, we could not find a threshold steady state CD34 count of any value predicting successful mobilization.
