[Relationship between the absolute lymphocyte count before or after autologous hematopoietic stem cell transplantation and the prognosis in patients with non-Hodgkin's lymphoma].

OBJECTIVE: To evaluate the relationship of the absolute lymphocyte count (ALC) before or after autologous hematopoietic stem cell transplantation (AHSCT), and the infused CD34(+) count with the relapse, disease-free survival (DFS), overall survival (OS) in non-Hodgkin's lymphoma (NHL) patients.
METHODS: A retrospective analysis of the relationship of the absolute lymphocyte count before (ALC-Pro) or 15 days after (ALC-15) the AHSCT, and the infused CD34(+) cell count with the relapse, DFS, OS of NHL.
RESULTS: ALC-Pro and ALC-15 were related to NHL relapse. The patients with high levels of ALC-Pro and ALC-15 had lower relapse rate. By Kaplan-Meier curve and COX multi-variable regression analysis, it was found that both ALC-Pro and ALC-15 were factors associated with the DFS. Patients infused high levels of CD34(+) cells had longer DFS. Patients with high levels of ALC-Pro, ALC-15, CD34(+) counts had longer OS.
CONCLUSION: ALC-Pro, ALC-15 and CD34(+) counts were significant in predicting relapse, DFS and OS for patients with NHL.
