Current Status and Limits:/High-dose chemotherapy with autologous haem
atopoietic stem cell rescue has become in recent years a widely accept
ed therapeutic modality for advanced stage breast cancer in North Amer
ica. The emergence of modern supportive measures like peripheral blood
stem cell rescue has significantly decreased the toxicity and cost of
high-dose chemotherapy. The rationale for use of escalated chemothera
py doses in breast cancer is the establishment of a dose-response rela
tionship, with higher doses producing increased response rates in prec
linical studies as well as in clinical trials.
