Komal Jhaveri, MD, of Memorial Sloan Kettering Cancer Center, discusses the latest updates from the SUMMIT trial, which explored the combinations of neratinib/fulvestrant/trastuzumab and neratinib plus trastuzumab, as well as fulvestrant alone. The combination regimens appeared to benefit patients with hormone–receptor positive, HER2-mutated metastatic breast cancer who have had prior exposure to CDK4/6 inhibitors, and those with HER2-mutated triple-negative disease (Abstract GS4-10).
Michael Gnant, MD, of the Medical University of Vienna, discusses phase III findings from the PALLAS study, which showed that adding 2 years of palbociclib to ongoing adjuvant endocrine therapy did not improve survival for patients with stage II to III hormone receptor–positive, HER2-negative early breast cancer.

The data showed that postmenopausal women with recurrence scores (RS) from 0 to 25 continue not to benefit from adjuvant chemotherapy, whereas premenopausal women with a RS from 0 to 25 did benefit from the addition of chemotherapy to endocrine therapy (Abstract GS2-07).
On October 12, 2021, abemaciclib was approved for use with endocrine therapy (tamoxifen or an aromatase inhibitor) for adjuvant treatment of adults with hormone receptor–positive, HER2-negative, node-positive, early breast cancer at high risk of recurrence and a Ki67 score ≥ 20%, as determined by...

Hans Wildiers, MD, of University Hospitals Leuven, discusses the final results from the phase IIb AIPAC study, which suggested that eftilagimod added to paclitaxel may be of benefit to patients older than 65 years with hormone receptor–positive, HER2-negative metastatic breast cancer after endocrine-based therapy. Eftilagimod, which is a first-in-class antigen presenting cell activator, appeared to increase circulating CD4/CD8 T cells, which correlated to improved overall survival (Abstract 948).
In a substudy of the ECOG-ACRIN E4112 cohort trial reported in JAMA Network Open, Fazeli et al found that approximately half of women with ductal carcinoma in situ (DCIS) undergoing magnetic resonance imaging (MRI) for pretreatment planning experienced fear or anxiety before and during the...

In the phase II coopERA Breast Cancer trial, which evaluated two endocrine neoadjuvant therapies in estrogen receptor–positive, HER2-negative early breast cancer, the oral selective estrogen receptor degrader giredestrant led to a greater reduction in Ki67 level—a measure of cancer cell...
Estrogen receptor–positive breast cancer is the most common type of breast cancer, diagnosed in more than 2.3 million women around the world each year, including more than 200,000 in the United States alone. Adjuvant endocrine therapy is a mainstay of treatment for these millions of women and is a...

Yongbae Kim, MD, of the Yonsei Cancer Center and Yonsei University College of Medicine, discusses findings that showed the use of internal mammary area irradiation (IMNI) in regional nodal irradiation did not significantly improve disease-free survival for women with node-positive breast cancer. However, patients with medially or centrally located tumors may be considered for treatment with IMNI (Abstract 2).
The invited discussant of BrighTNess,1 Monica Arnedos, MD, PhD, Head of the Breast Cancer Research Program at the Institut Bergonié in Bordeaux, France, said the findings add to growing support for using carboplatin in triple-negative breast cancer, but their clinical application could be...

A “big problem, maybe the major one,” with risk-reducing medications for breast cancer is low uptake among women at high risk of breast cancer,” Seema A. Khan, MD, told participants at the 2021 Annual Lynn Sage Breast Cancer Symposium.1 Dr. Khan is Professor of Surgery and the Bluhm Family...
Risk-reducing medications for breast cancer may be effective for many women, and recently reported and ongoing trials have led to improvements in their tolerability and safety, Seema A. Khan, MD, reported at the 2021 Annual Lynn Sage Breast Cancer Symposium (virtual).1 Dr. Khan is Professor of...
“Nodal status remains the single most important prognostic marker in outcomes for women with estrogen receptor–positive, HER2-negative breast cancer. For that reason, it makes sense to think about optimizing adjuvant therapy, including endocrine treatments, chemotherapy, and targeted therapy,”...
In a Korean phase III trial reported in JAMA Oncology, Kim et al found that the addition of internal mammary node irradiation to adjuvant regional nodal irradiation did not improve 7-year disease-free survival in women with node-positive breast cancer. In an ad hoc analysis, however, benefit was...
In a study reported in the Journal of Clinical Oncology, Yadav et al found that germline pathogenic variants in the cancer predisposition genes ATM, BRCA2, CDH1, CHEK2, and PALB2 were associated with an increased risk of invasive lobular carcinoma of the breast, with no association with BRCA1...
