title: [Chemotherapy with autologous stem cell support for breast cancer].
abstract: The importance of dose intensity in breast cancer chemotherapy has been stressed in recent years with clear correlations demonstrated between dose intensity and clinical outcome of the patients in both therapeutic and adjuvant settings. In addition to various and intense supportive care, autologous stem cell support (ASCS) has been used over the past 15 years in order to overcome myelotoxicity of cancer chemotherapy. ASCS was initially practiced in the form of bone marrow transplantation, and more recently peripheral stem cell transplantation has been combined in addition to administration of G-CSF. Our pilot study in patients with recurrent/advanced breast cancer showed a higher response rate and a higher survival rate as compared to conventional chemotherapy, and there have been some long-term disease-free survivors with probable cures among complete responders with ASCS-supported chemotherapy. In adjuvant settings for patients with a high risk for recurrence who had been given a high-dose, the ASCS-supported regimen showed a higher disease-free survival rate as compared to those who were treated with conventional adjuvant therapy. Whether these apparently better results in our pilot studies hold true generally remains to be seen with well-scheduled randomized clinical trials.
