title: Cytotoxic treatment of metastatic breast cancer. Which drugs and drug combinations to use?
abstract: Although the optimal efficacy of cytotoxic therapy plateaued in the 1970s, no consensus yet exists regarding which cytotoxic combination to offer as first-line therapy for metastatic breast cancer. Comparison of a combination of CAF/CEF with other cytotoxic combinations reveals that an anthracycline-containing regimen not only increases response rate, but also improves time to progression and survival. Regarding appropriate duration of cytotoxic therapy, randomized trials indicate that therapy in excess of 6 months is beneficial. Although the main objective of cytotoxic therapy in patients with metastatic disease is to palliate symptoms at the least toxic cost, the finding that adjuvant cytotoxic therapy improves survival provides a clinical and ethical rational for continued research into new drugs and combinations in the hope that new strategies can be employed not only against metastatic breast cancer but may be applied with benefit also in the adjuvant situation.
