Metastatic breast cancer (MBC) is cancer that has spread from the breast to another
part of the body or has come back in another distant location. Treatment options for
MBC depend on several factors. One of these factors is the levels of hormone receptors
(HRs) in the tumor. Cancers with high levels of HRs, called HR-positive, use the hormones
estrogen and progesterone to grow and spread. Hormonal therapy is a type of treatment
specifically for HR-positive breast cancer. This expert group used data from published
literature, practical experience and opinion of a large group of academic oncologists
to arrive at these practical consensus recommendations in regards with the use of
hormonal therapy and the management of HR-positive MBC for the benefit of community
oncologists.
