BACKGROUND: Rapid hematological engraftment at autologous peripheral stem cell transplantation (APSCT) is a significant factor in reduction of early transplant-related complications and costs. For this reason, it is important to determine influences on hematological recovery. METHODS: This study was designed to evaluate factors affecting leukocyte and platelet engraftment times after high dose chemotherapy following APSCT. A total of 228 patients (131 males and 97 females) were enrolled. RESULTS: There were statistically significant differences between patients with CD34+ cell doses ≥ 2.5 x 10⁶/kg (n=180) and < 2.5 x 10⁶/kg (n=48), regarding leukocyte engraftment at 11 and 12 days, respectively (p<0.02), between G-CSF (n=167) and GM-CSF (n=61) posttransplant regarding median leukocyte engraftment times (p=0.005), and between with (n=75) or without (n=153) history of pretransplant radiotherapy for both leukocyte and platelet engraftment times (p<0.001). CONCLUSIONS: For leukocyte engraftment, a history of pretransplant radiotherapy, type of growth factor used and number of CD34+ cells infused, and for platelet engraftment, a history of pretransplant radiotherapy were found to be independent variables on multivariate analysis with the Cox regression method.
