A trial for peripheral blood stem cell harvest by combination of G-CSF with ABVD regimen in the management of Hodgkin's disease

We studied the possibility of performing peripheral blood stem cell (PBSC) harvests during the course of ABVD therapy by adding G-CSF to the treatment regimen. Six patients with high-risk Hodgkin's disease (HD) (5 untreated cases with bulky mass and 1 relapsed case) received G-CSF (5 micrograms/kg) subcutaneously from day 8 to day 13 of their first course of ABVD treatment; the numbers of CD34+ cells and CFU-GM were monitored. PBSC harvests were performed on day 12 and day 13 of subsequent ABVD plus G-CSF treatment courses. For all patients tested, we were able to harvest CFU-GM (3.78 +/- 1.19 x 10(5) colonies/kg) for peripheral blood stem cell transplants (PBSCT) by performing 2 to 4 cycles. of apheresis, without any modification to the original ABVD protocol. These findings suggest that ABVD plus G-CSF therapy is a strong candidate for the treatment of patients with high-risk HD who may undergo autologous PBSCT.
