Breast Cancer 2022–2023 Almanac
The past year has been an exciting time for breast oncologists and patients with all stages of breast cancer, with new agents approved and long-term results from pivotal trials showing improved survival for patients with metastatic disease. Let’s take a look at some of the highlights in early-stage ...
EBCTCG Meta-analysis Confirms Benefit of Ovarian Ablation or Suppression in Preventing Breast Cancer Recurrence
A meta-analysis of randomized trials has revealed a benefit to ovarian ablation or suppression in preventing breast cancer recurrence in premenopausal women with estrogen receptor–positive tumors.1 The findings, based on almost 15,000 women in studies spanning several decades, were presented at the ...
Update From monarchE: Benefit of Abemaciclib Increases Over Time in Early-Stage Breast Cancer
Results of a planned interim overall survival analysis of the phase III monarchE trial offered further support for the addition of abemaciclib to adjuvant endocrine therapy for patients with hormone receptor–positive, HER2-negative, node-positive, high-risk disease, according to Stephen R.D....
EMERALD Trial: Elacestrant vs Standard Endocrine Monotherapy for Advanced Breast Cancer After CDK4/6 Inhibition
Elacestrant—an investigational oral selective estrogen receptor degrader (SERD)—achieved longer progression-free survival vs standard-of-care endocrine monotherapy as second- or third-line therapy in patients with estrogen receptor–positive, HER2-negative advanced or metastatic breast cancer in the ...
T-DXd Confirmed as Preferred Second-Line Therapy for Metastatic HER2-Positive Breast Cancer
The antibody-drug conjugate fam-trastuzumab deruxtecan-nxki (T-DXd) proved to be superior to the antibody-drug conjugate ado-trastuzumab emtansine (T-DM1), significantly improving progression-free survival and overall survival, in women with unresectable or metastatic HER2-positive breast cancer as ...
Palbociclib/Fulvestrant Does Not Improve Progression-Free Survival After Progression on a CDK4/6 Inhibitor in Metastatic Breast Cancer
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,...
Capivasertib Plus Fulvestrant Doubles Progression-Free Survival in Hormone Receptor–Positive, HER2-Negative Advanced Breast Cancer
The combination of capivasertib, an AKT pathway inhibitor, plus fulvestrant, an estrogen receptor antagonist, significantly improved progression-free survival compared with fulvestrant alone in patients with hormone receptor–positive, HER2-negative advanced breast cancer, according to results of...
SOFT Analysis: Breast Cancer Index May Identify Which Patients Need Ovarian Suppression
In an analysis of the SOFT trial, the Breast Cancer Index accurately identified premenopausal women with hormone receptor–positive early breast cancer who may benefit from ovarian function suppression in addition to adjuvant endocrine therapy. The findings were reported by Ruth O’Regan, MD, Chair...
Can Younger Women With Hormone Receptor–Positive Breast Cancer Safely Pause Endocrine Therapy to Pursue Pregnancy?
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...
Overall Survival in Two Monarch Trials of Abemaciclib in Advanced Breast Cancer
Overall survival results from two trials of abemaciclib in advanced breast cancer were reported at the European Society for Medical Oncology (ESMO) Congress 2022. Both MONARCH 3 and monarcHER previously met their primary endpoints of progression-free survival. The current results for overall...
Recent FDA Approvals in Breast Cancer
Over the past year, the U.S. Food and Drug Administration (FDA) granted approval to several novel drugs and expanded indications for older therapeutic agents used in breast cancer.
Abemaciclib Plus Endocrine Therapy
On March 3, 2023, the FDA expanded the indication for abemaciclib with endocrine...
Extended Follow-up of TROPiCS-02 Trial: Sacituzumab Govitecan in Metastatic Breast Cancer
Additional follow-up of the phase III TROPiCS-02 trial has upheld the progression-free and overall survival benefit seen with sacituzumab govitecan-hziy compared with physician’s choice of treatment in patients with endocrine-resistant, hormone receptor–positive, HER2-negative metastatic breast...
Adjuvant Treatment With Ribociclib Reduces Risk of Recurrence in Hormone Receptor–Positive, HER2-Negative, Early-Stage Breast Cancer
The addition of the CDK4/6 inhibitor ribociclib to endocrine therapy significantly improved invasive disease–free survival in women with hormone receptor–positive, HER2-negative, early-stage breast cancer. These results of the phase III NATALEE trial were reported by lead author Dennis J. Slamon,...
Should CDK4/6 Inhibitors Be a First-Line Option for Advanced Hormone Receptor–Positive, HER2-Negative Breast Cancer?
Two studies presented at the 2023 ASCO Annual Meeting challenge the use of CDK4/6 inhibitors as part of upfront treatment of advanced hormone receptor–positive, HER2-negative breast cancer. The first, the SONIA trial, found that first-line treatment with CDK4/6 inhibitors led to greater toxicity...
