Mobilization of Peripheral Blood Stem Cells Using Regimen Combining Docetaxel with Granulocyte Colony-stimulating Factor in Breast Cancer Patients.
ABSTRACT To evaluate the effectiveness and safety of the mobilization of peripheral blood hematopoietic stem cells by combining docetaxel with granulocyte colony-stimulating factor (G-CSF) in breast cancer patients.
A total of 57 breast cancer patients were treated with docetaxel 120 mg/m. When the white blood cell (WBC) count decreased to 1.0×10/L, patients were given G-CSF 5 μg/kg daily by subcutaneous injection until the end of apheresis. Peripheral blood mononuclear cells (MNC) were isolated by Cobe Spectra Apheresis System. The percentage of CD34 cell was assayed by flow cytometry.
At a median 6 of days (range 3-8) after the administration of docetaxel, the median WBC count decreased to 1.08×10/L (range 0.20-2.31). The median duration of G-CSF mobilization was 3 days (range 2-7). The MNC collection was conducted 8-12 days (median 10 days) after docetaxel treatment. The median MNC was 5.35×10/kg (range 0.59-14.07), the median CD34 cell count was 2.43×10/kg (range 0.16-16.69). The CD34 cell count was higher than 1.00×10/kg in 47 of 57 cases (82.46%) and higher than 2.00×10/kg in 36 cases (63.16%). The CD34 cell count was higher than 2.00×10/kg in 27 collections (23.68%). The MNC count and the CD34 cell count were correlated with the bottom of WBC after docetaxel chemotherapy (r=0.364, 0.502, =0.005, 0.000). The CD34 cell count was correlated with the MNC count (r=0.597, =0.000). The mobilization and apheresis were well tolerated in all patients. Mild perioral numbness and numbness of hand or feet were observed in 3 cases. No serious adverse events were reported.
Mobilization of peripheral blood hematopoietic stem cell by combining docetaxel with G-CSF was effective and safety in breast cancer patients.
Article: Selections of appropriate regimen of high-dose chemotherapy combined with adoptive cellular therapy with dendritic and cytokine-induced killer cells improved progression-free and overall survival in patients with metastatic breast cancer: reargument of such contentious therapeutic preferences.[Show abstract] [Hide abstract]
ABSTRACT: BACKGROUND: We hypothesized that combination of dendritic cell (DC) with autologous cytokine-induced killer (CIK) immunotherapy in setting of high-dose chemotherapy (HDC) would be effective for selected metastatic breast cancer (MBC) patients. PATIENTS AND METHODS: Our previous work showed thiotepa could eradicate breast cancer stem cells. From 2004 to 2009, 79 patients received standard dose chemotherapy (SDC) of 75 mg/m(2) docetaxel and 75 mg/m(2) thiotepa versus 87 patients of HDC + DC/CIK: 120 mg/m(2) docetaxel to mobilize peripheral CD34(+) progenitor cells, a sequence of HDC (120 mg/m(2) docetaxel, plus 175 mg/m(2) thiotepa) + DC/CIK, with or without 400 mg/m(2) carboplatin depending upon bone marrow function. The endpoints were response rates (RR), progression-free survival (PFS), and overall survival (OS). RESULTS: Compared with SDC, PFS and OS were improved in HDC + DC/CIK (median PFS 10.2 vs. 3.7 months, P < 0.001; median OS 33.1 vs. 15.2 months, P < 0.001). Patients of pre-menopausal, HDC as first-line treatment after metastasis, or with visceral metastasis showed prolonged PFS and OS. SDC group also achieved the similar response as previous reports. CONCLUSION: Our study demonstrated the novel combination of HDC with DC/CIK to be an effective choice for the selected MBC population, in which choosing appropriate chemo regimens played important roles, and also specific HDC regimen plus DC/CIK immunotherapy showed the clinical benefits compared with chemotherapy alone.Clinical and Translational Oncology 01/2013; · 1.28 Impact Factor
