MAC15 RxPONDER trial presented at the San Antonio Breast Cancer Symposium

Postmenopausal women with hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative breast cancer that has spread to a limited number of lymph nodes, and whose recurrence risk is relatively low, do not benefit from chemotherapy when it is added to hormone therapy, according to initial results from the MAC15 RxPONDER trial presented at the 2020 San Antonio Breast Cancer Symposium. These findings may save tens of thousands of postmenopausal women each year the time, money, and harmful side effects that come with chemotherapy infusions.

Precision medicine targeting each individuals unique form of cancer

The rise of precision medicine

Today we think about cancer in terms of the tumour site—breast, lung, colon, brain, each is separate with different treatments. Precision medicine is a new way of looking at cancer. Instead of focusing on the site of the cancer, it identifies the genetic abnormalities that make cancer possible in individual patients.
