This study aimed to evaluate the efficiency of DHAP regimen plus filgrastim for mobilization of stem cells in patients with recurrent and/or refractory lymphoma. Thirty-four patients who took DHAP as salvage therapy prior to autologous stem cell transplantation were included. After chemotherapies, 2 cycles of DHAP plus filgrastim were administered to the patients. Stem cells from 32 patients (94%) were collected on median 11th day (8-12), and the median collected CD34(+) cell dose was 9.7 x 10(6)/kg (range 3.8-41.6). DHAP plus filgrastim was found to be an effective chemotherapy regimen in mobilizing CD34(+) stem cells into the peripheral. (c) 2016 Elsevier Ltd. All rights reserved.
