Summary
At this year’s American Society of Clinical Oncology (ASCO) annual meeting two large phase 3 trials, the ABCSG-18 and the D‑CARE study, analysed the effects of adjuvant denosumab in breast cancer patients and reported different outcomes. Another phase 3 study, the ASTRRA trial, investigated the use of adjuvant ovarian function suppression (OFS) in high-risk premenopausal patients. This trial confirmed the benefit of OFS similar to the results of the already published SOFT/TEXT trials but raises some crucial questions on the optimal duration of OFS in these patients. The results of the SOFT/TEXT trials were also updated at this meeting.
