High-dose chemotherapy in the treatment of breast-cancer
Abstract:
Dose is a critical determinant of the efficacy of chemotherapy. The dose response curve for virtually all anticancer agents is steep in both in vitro and in vivo experimental studies. However the application of the steep dose-response curve in the clinic has been troublesome for many years because of dose limiting bone marrow toxicity. Hematopoietic support with growth factors and/or peripheral stem cell transplantation now offers new possibilities to push doses up to levels where non-myeloid toxicity becomes dose limiting. Several trials applying high dose chemotherapy with stem cell support have been conducted in breast cancer. They showed a higher response rate and a higher percentage complete remissions compared with conventional treatment. Follow-up is short for most studies but some long-term complete remissions are reported. Developments in this field are reviewed.

Cancer Therapies
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...
