Multivariate analyses of prognostic factors associated with hematopoietic recovery in autograft patients with different sources of progenitor cells. A GATMO experience. Argintine Group of Bone Marrow Transplant.
OBJECTIVE
To evaluate in a multivariate analysis the prognostic factors associated with hematopoietic recovery and the supportive care requirements after autotransplant of progenitor cells (PC) from various sources: bone marrow (BMPC), BMPC & peripheral blood (PBPC), and PBPC alone.


METHODS
A total of 570 patients with hematological malignancies and solid tumors underwent high-dose therapy followed by autotransplant. PBPC were obtained after mobilization with chemotherapy and/or cytokines. One-hundred five patients received BMPC, 217 received BMPC & PBPC and 248 PBPC alone; all of the patients received G-CSF or GM-CSF after infusion.


RESULTS
In a multivariate analysis the recovery of neutrophils was adversely associated with low numbers of nucleated cells infused (P < 0.13), bone marrow progenitor cell source, and diagnosis of multiple myeloma and acute leukemia (P < 0.001). The factors that adversely affected platelet recovery were low number of nucleated cells and diagnosis of multiple myeloma and acute leukemia (P < 0.001).


CONCLUSIONS
We conclude that BMPC adversely affect neutrophil recovery while low numbers of nucleated cells and diagnosis of multiple myeloma and acute leukemia adversely affect both neutrophil and platelet recovery.
