This summary table contains detailed information about research studies. Summary tables are a useful way to look at the science behind many breast cancer guidelines and recommendations. However, to get the most out of the tables, it’s important to understand some key concepts. Learn how to read a research table.
Introduction: Many chemotherapy drug combinations can be used to treat early breast cancer.
Anthracycline chemotherapy drugs used to treat breast cancer are:
The Early Breast Cancer Trialists’ Collaborative Group combined the results of 17 randomized clinical trials that compared chemotherapy combinations with and without an anthracycline drug.
They found drug combinations containing an anthracycline improved overall survival (about 3 percent at 5 years and 4 percent at 10 years) .
Taxane chemotherapy drugs used to treat breast cancer are:
Studies have shown adding a taxane drug to chemotherapy with an anthracycline increases 5-year overall survival [2-3].
