We prospectively evaluated docetaxel (100 mg/m2) with g-csf (10 μg/kg s.c., daily) for mobilization efficiency in 26 patients with breast cancer. the minimum target yield was >4.5 × 106 CD34+ cells/kg (optimum = 9 × 106/kg), sufficient to support the subsequent three cycles of high-dose therapy (HDT). The peak days for peripheral blood (PB) CD34+ cells were day 8 and day 9. Seven collections began on day 7, 16 on day 8 and three on day 9. The median peripheral blood progenitor cell (PBPC) CD34+ cell content ranged from 1.2 to 5.9 × 106/kg per day during days 7 to 11 with a median CD34+ content of the total 72 PBPC collections of 3.4 × 106/kg (0.07–15.6). Fifteen patients obtained a PBPC collection exceeding 5 × 106/kg on a single day of collection. Following a median 3 days collection for each patient (range 2–4), the median total CD34+ for all individual sets of collections was 9.7 × 106/kg (range 1.0–28.4). We were able to achieve the minimum CD34+ cell target yield in 22 of 26 patients with one cycle of mobilisation chemotherapy and in two of these patients a second collection yielded sufficient cells. twenty-two patients have subsequently received repetitive hdt and pbpc transplantation with 57 cycles of hdt having been delivered. for all 57 cycles, the median time to absolute neutrophil count (anc) >0.5 × 109/l and 1.0 × 109/l was 10 days (range 8–22) and 11 days (range 8–23), respectively. The median time to platelets greater than 20 × 109/l, 50 × 109/l and 100 × 109/l was 13 days (range 11–23), 17 days (range 12–53) and 23 days (range 18–70), respectively. We conclude that docetaxel with G-CSF effectively mobilises PBPCs with apheresis needing to... [ABSTRACT FROM AUTHOR]
