Details and patient eligibility

About

The combination of taxanes, and especially docetaxel, with an anthracycline seems to be an important part of the chemotherapy regimens used in the adjuvant setting of patients with early-stage node-positive breast cancer patients. Whether sequential or concurrent administration of these drugs is preferable is not yet known, especially in patients with node-negative high risk tumors.
