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.

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.
