Minimal residual disease in autologous hematopoietic harvests from breast cancer patients

Abstract

The increasing use of high-dose chemotherapy with autologous hematopoietic transplantation for the treatment of solid malignancies has raised concern about the role of tumor cells contaminating the grafts. Minimal residual disease (MRD) in autologous grafts has became a dynamic and intensively studied field in oncology. This review discusses the current status of MRD in breast cancer autografts and presents existing data on detection methodology, clinical relevance, biologic characteristics and purging techniques.
