The combination of palbociclib and fulvestrant did not prolong progression-free survival compared to fulvestrant alone in patients with hormone receptor–positive/HER2-negative metastatic breast cancer who had disease progression on prior treatment with a CDK4/6 inhibitor and endocrine therapy,...
Preserving fertility is a driving concern for many young women with breast cancer. Many of these women have hormone receptor–positive breast cancer and are treated with adjuvant endocrine therapy for 5 to 10 years, which is known to compromise fertility. Younger women who may want to take a break...
The oral selective estrogen receptor degrader (SERD) camizestrant improved progression-free survival, as compared with fulvestrant, in previously treated postmenopausal women with advanced breast cancer in the phase II SERENA-2 trial. These results were reported at the 2022 San Antonio Breast...
A pilot study provides a signal that the novel HER2 antibody-drug conjugate fam-trastuzumab deruxtecan-nxki (T-DXd), is active in the neoadjuvant setting in patients with HER2-low breast cancer.

Sean Khozin, MD, MPH, of the Massachusetts Institute of Technology, discusses the “external validity deficits” of randomized clinical trials, which still involve only about 5% of adults with cancer, who may differ in important ways from real-world populations. Dr. Khozin describes the reasons for low levels of participation and advocates for capturing the experience of patients not represented in traditional clinical trials, so real-world data can address these validity deficits.
In updated analyses from the phase III HER2CLIMB trial reported in JAMA Oncology, Nancy U. Lin, MD, and colleagues found that the addition of tucatinib to trastuzumab and capecitabine showed improved outcomes among previously treated patients with HER2-positive breast cancer and baseline brain...

Long-term recurrence and survival data are now available from the groundbreaking TAILORx trial. With 12 years of follow-up, the updated analysis—reported by Sparano et al at the San Antonio Breast Cancer Symposium (SABCS) 2022 (Abstract GS1-05)—confirms the original findings that chemotherapy may...
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.
The latest analysis of the TROPiCS-02 breast cancer trial shows that sacituzumab govitecan-hziy is effective in patients with a wide range of Trop-2 expression levels. The findings were reported at the 2022 San Antonio Breast Cancer Symposium by Hope S. Rugo, MD, FASCO, Professor of Medicine and...
Results of a planned interim overall survival analysis of the phase III monarchE trial offer further support for the addition of abemaciclib to adjuvant endocrine therapy for patients with hormone receptor–positive, HER2-negative, node-positive, high-risk breast cancer, according to Stephen R.D....
Andrea De Censi, MD, PhD, of Italy’s E.O. Ospedali Galliera, discusses phase III findings showing that low-dose tamoxifen (so-called babytam) given for 3 years still significantly prevents recurrences from noninvasive breast cancer after a median of 7 years from treatment cessation. Babytam at 5 mg/d for 3 years significantly lowered recurrence from noninvasive breast cancer at 10 years without “excess” adverse events (Abstract GS4-08).
Ann H. Partridge, MD, MPH, of Dana-Farber Cancer Institute, discusses results from the POSITIVE trial, which showed that a temporary interruption of endocrine therapy in women with hormone-responsive breast cancer in order to attempt pregnancy, does not affect short-term disease outcomes. The study found that 74% of women had at least one pregnancy, most (70%) within 2 years. Birth defects were low (2%) and were not clearly associated with treatment exposure. Dr. Partridge explains that these data stress the need to incorporate patient-centered reproductive health care in the treatment and follow-up of young women with breast cancer (Abstract GS4-09).
