RESUMO

The purpose of this study was to develop a cost-effective protocol for the mobilization of peripheral blood stem cells (PBSC) in patients with malignancy. Thirty consecutive patients were randomized to mobilize PBSC with the late addition of a standard 250 microg dose of G-CSF (Neutrogen) from day 8 or early addition of the same dose of G-CSF from day 2, following cyclophosphamide (CY) 4 g/m2. The median yield of CD34+ cells from evaluated patients was 7.87 x 10(6)/kg (range, 2.06-27.25), collected in a median of four apheresis (range, 2-9). Target CD34 + cell doses > or = 2.0 x 10(6)/kg were achieved in all patients able to be evaluated. There were no statistically significant differences in CD34+ cell yields or toxicities. Overall engraftment occurred with median days to neutrophils > or = 0.5 x 10(9)/L or platelets > 20 x 10(9)/L of 11 and 17 days, respectively. However, the duration of G-CSF administration was markedly shorter in the late use of G-CSF group than in the early use of G-CSF group, with a median of 9 days compared with 15 days (p>0.001). PBSC harvesting after priming with CY plus delayed use of G-CSF made it a safe and cost-effective procedure.

RESUMO

Granulocyte colony stimulating factors (G-CSFs) play a very important role in the current technique of stem cell transplantation. The conventional timing of administration of G-CSF in both mobilization and post transplantation has been right after chemotherapy or right after transplantation. We have studied the effects of timing of administration of G-CSF in 21 patients who had autologous stem cell transplantation for breast cancer, lymphoma or nasopharyngeal cancer. Their stem cells were mobilized by chemotherapy followed by G-CSF, which were given on day +1 or day +5 after chemotherapy. The median peak percentage of CD34 positive cells harvested using both technique were 1.88 and 0.48% respectively. After transplantation, G-CSF were given on day +1 or day +6 after stem cell infusion until neutrophil recovery. The time until bone marrow recovery was significantly longer in the group with delayed administration of G-CSF (10 days versus 8 days). However, there was no difference in duration of neutropenic fever or hospital stay after transplantation. The transplantation outcome was also unaffected. We therefore concluded that G-CSF can be given in the delayed fashion in both mobilizing and post transplantation settings without jeopardizing the outcome and this would result in a significant cost saving.
