Prudence A. Francis, MD, on Premenopausal ER-Positive Breast Cancer: Past, Present, and Future

Prudence A. Francis, MD, of the Peter MacCallum Cancer Centre, discusses an update of the SOFT trial, which showed that adding ovarian function suppression (OFS) to adjuvant tamoxifen for premenopausal women with estrogen receptor (ER)-positive breast cancer reduces the risk of recurrence. OFS enables the use of adjuvant aromatase inhibitors as an alternative to tamoxifen, which can further reduce recurrence of ER-positive, HER2-negative disease. Very young women—those younger than 35 years old—should be considered for OFS, according to Dr. Francis. In addition, tamoxifen alone is appropriate in women with low-risk clinical-pathologic features.
