Docetaxel-anthracycline combinations in metastatic breast cancer.
The taxanes and anthracyclines have emerged as the most active agents for treating women with advanced breast cancer. As such, investigation of the two drug classes in combination regimens has been eagerly pursued. The rationale for combining docetaxel with an anthracycline includes high clinical activity of each individual agent, lack of complete clinical cross resistance, and non-overlapping toxicity profiles. Phase II trials of the docetaxel combinations with either doxorubicin or epirubicin showed high activity, with acceptable tolerability in patients with metastatic breast cancer. Consequently, three randomized trials have compared docetaxel-anthracycline-based regimens with standard anthracycline-based polychemotherapies as first-line therapy for women with advanced breast cancer. Improved outcome was reported in favor of the docetaxel-anthracycline combinations, with manageable hematologic toxicity and favorable non-hematologic safety profiles. Therefore, docetaxel-anthracycline combinations represent a validated option in first-line treatment for women with advanced breast cancer, and are further evaluated as adjuvant treatment for early stage breast cancer, with already promising prospects and the potential to change the natural history of breast cancer.
