Abstract:
Within the last several decades adjuvant polychemotherapy for breast cancer has evolved with the development of anthracyclines and taxanes. Parallel to these developments, granulocyte-colony stimulating factor support has permitted the safe delivery of chemotherapy at shorter ('dose-dense') intertreatment intervals, which, as predicted by preclinical models, has further improved survival. Recently, insights into tumor biology have led the development of targeted therapies, such as trastuzumab for HER2-positive disease, and this has now been successfully incorporated into dose-dense therapy. Newer targeted agents may be similarly incorporated into dose-dense regimens to further improve patient outcomes. This article reviews dose-dense therapy and discusses its role as a chemotherapy foundation for additional targeted agents.

However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
