title: The role of high-dose chemotherapy with autologous bone marrow transplantation in the treatment of breast cancer.
abstract: Autologous bone marrow reinfusion rapidly repopulates severely damaged bone marrow thus shortening the period of myelosuppression following high-dose chemotherapy programs. This strategy has been successfully employed in several hematologic malignancies such as acute leukemia, Hodgkin's disease, non-Hodgkin's lymphoma, and chronic myelogenous leukemia. More recently a number of clinical trials have investigated the role of high-dose chemotherapy with autologous bone marrow transplant in solid tumors. This strategy, when used in patients with advanced refractory metastatic breast cancer, results in a high objective response rate (30-70%) but most of these remissions are of short duration (3-4 months). When using high-dose single agents complete remissions are rare; with combination chemotherapy they are more frequent (20-50%). The utilization of high-dose chemotherapy with autologous marrow transplant as a consolidation after achieving a partial or complete remission with standard chemotherapy has shown more promising results with complete remissions approaching 70% in some series. The impact of any of these strategies on overall survival of patients with metastatic breast cancer remains to be demonstrated. The optimal patient selection criteria and strategies for additional development of this field are discussed.
