Four trials of high-dose chemotherapy with stem cell support in breast canc
er in the adjuvant and metastatic settings have shown no long-term disease-
free or overall survival gain. This relative failure of a single high-dose
therapy we believe opens up the development of a dose-dense approach with b
lock scheduling as the most promising way forward. This intensive chemother
apy can be more easily combined with the newer biological therapies and our
prediction is that this will prove to be the most effective treatment in t
he future for women with poor risk breast cancer.
