"We provide compelling new experimental evidence that androgen receptor stimulating drugs can be more effective than existing (e.g. Tamoxifen) or new (e.g. Palbociclib) standard-of-care treatments and, in the case of the latter, can be combined to enhance growth inhibition," said Wayne Tilley, Director of the Dame Roma Mitchell Cancer Research Laboratories, Adelaide Medical School, University of Adelaide.
Androgens were historically used to treat breast cancer, but knowledge of hormone receptors in breast tissue was rudimentary at the time and the treatment's efficacy misunderstood. Androgen therapy was discontinued due to virilising side effects and the advent of anti-estrogenic endocrine therapies. While endocrine therapy is standard-of-care for estrogen receptor positive breast cancer, resistance to these drugs is the major cause of breast cancer mortality.
"The new insights from this study should clarify the widespread confusion over the role of the androgen receptor in estrogen receptor driven breast cancer," said Elgene Lim, a breast oncologist and Head of the Connie Johnson Breast Cancer Research Lab at the Garvan Institute. "Given the efficacy of this treatment strategy at multiple stages of disease in our study, we hope to translate these findings into clinical trials as a new class of endocrine therapy for breast cancer."
