Breast Cancer Treatment Guidelines

The faculty in the Breast Oncology Program at Dana-Farber Brigham Cancer Center have developed guidelines on how to best utilize certain treatments recently approved by the Food and Drug Administration (FDA). The guidelines were drafted using data from available clinical trials and presented for feedback and expert consensus to a diverse group of Dana-Farber Brigham physicians, nurses, clinical investigators, lab investigators, translational researchers, administrators, and patient advocates. We are pleased to share our recommended guidelines which may be a helpful reference when using these new agents. In our discussions, we considered:
