A large body of data on systemic therapy has been presented and published i
n the past year, including new information on primary risk reduction, patie
nt selection for adjuvant systemic therapy, and anthracycline-analogs. New
data on ongoing adjuvant trials (including taxane studies), unpublished upd
ates from the fourth Oxford Overview in September 2000, and provocative dat
a on ovarian ablation were important features of the November 2000 National
Institutes of Health Consensus Development Conference on Adjuvant Therapy
for Breast Cancer. Important new data on anti-estrogen therapy, including a
romatase inhibitors and pure antiestrogens, further expand the role of the
oldest targeted breast cancer therapy. Trastuzumab and other novel compound
s are being investigated as single-agents and in combination with conventio
nal systemic approaches. Discussions on the long-term effects of adjuvant t
herapy have taken center stage also. These and other important ongoing deve
lopments since 2000 are examined in this review article. Curr Opin Oncol 20
