Antoinette R. Tan, MD, MHSc, discussed the promise of oral SERDs as they continue to be developed for the treatment of patients with ER-positive, HER2-negative breast cancer, factors that inform treatment decisions following disease progression on a CDK4/6 inhibitor, and the growing role of antibody-drug conjugates across the breast cancer spectrum.

Lida A. Mina, MD, discusses the evolving role of ADCs across breast cancer subtypes, current data on the use of CDK4/6 inhibitors in HR-positive, HER2-negative breast cancer, and the increased use of genomic testing and NGS to improve the sequencing of agents in triple-negative breast cancer.

A statewide policy intervention that discouraged initial breast cancer surgical care for patients with Medicaid insurance in low-volume facilities led to a survival benefit.

Capivasertib plus fulvestrant provided a clinically meaningful improvement in progression-free survival over fulvestrant alone in patients with hormone receptor–positive advanced breast cancer, including those who previously received a CDK4/6 inhibitor, chemotherapy in the advanced setting, or had baseline liver metastases.

Comprehensive insight on the treatment armamentarium currently available to patients with HER2+ metastatic breast cancer and CNS disease.

Expert oncologist Kevin Kalinsky, MD, MS, reviews a patient case of HER2+ metastatic breast cancer and highlights key findings in this disease setting.

The combination of OP-1250 and palbociclib produced a tolerable safety profile and elicited tumor responses and disease stabilization in patients with hormone receptor–positive, HER2-negative metastatic breast cancer.

The frontline combination of ribociclib and letrozole significantly prolonged overall survival over letrozole alone in a subset of patients with hormone receptor–positive, HER2-negative advanced breast cancer who had de novo metastatic disease or late recurrence from neoadjuvant therapy, according to data from an exploratory analysis of the phase 3 MONALEESA-2 trial.

The addition of atezolizumab to neoadjuvant chemotherapy generated numerical improvements in event-free survival, disease-free survival, and overall survival compared with chemotherapy plus placebo in patients with early-stage triple-negative breast cancer.

Sacituzumab govitecan-hziy produced comparable efficacy outcomes for patients with metastatic triple-negative breast cancer who had a higher incidence of grade 2 or 3 diarrhea and neutropenia vs patients in the overall population, according to a post hoc analysis of the phase 3 ASCENT trial presented at the 2023 ESMO Breast Cancer Annual Congress.

Fam-trastuzumab deruxtecan-nxki was associated with better efficacy outcomes compared with treatment of physician’s choice in patients with HER2-low, estrogen receptor-low metastatic breast cancer, according to findings from a subgroup analysis of the phase 3 DESTINY-Breast04 study.

Administration of trilaciclib followed by sacituzumab govitecan showed early signals of efficacy and may reduce the incidence of adverse effects in heavily pretreated patients with unresectable locally advanced or metastatic triple-negative breast cancer, according to preliminary results from a phase 2 study.

Olaparib provided consistent clinical benefit in patients with germline BRCA-mutated, HER2-negative metastatic breast cancer, irrespective of estrogen receptor expression level.

Adjuvant abemaciclib with endocrine therapy led to a tolerable safety profile in patients with hormone receptor-positive, HER2-negative, node-positive, high-risk, early breast cancer,

Elacestrant maintained the quality of life for patients with metastatic breast cancer for at least 6 treatment cycles, according to patient reported outcomes.

Karen S. Anderson, MD, PhD, discusses novel and emerging therapies, as well as potential future targets, for the treatment of patients with hormone receptor–positive breast cancer.

Neelam Desai, MD, discusses the toxicity profile of fam-trastuzumab deruxtecan-nxki in HER2-positive breast cancer.

Treatment with adjuvant anastrozole over a 10-year period remained tolerable and increased disease-free survival rates in postmenopausal women with hormone receptor–positive breast cancer, according to data from the phase 3 AERAS trial.

Karen S. Anderson, MD, PhD, discusses the evolution of antibody-drug conjugates in the treatment of different subgroups of patients with metastatic breast cancer.

Karen S. Anderson, MD, PhD, discusses emerging data and role for CDK4/6 inhibitors in the treatment of patients with hormone receptor–positive, HER2-negative breast cancer, along with the growing use of antibody-drug conjugates across the breast cancer spectrum and updates in triple-negative breast cancer.

Stephanie L. Graff, MD, discusses current and planned investigations of the emerging antibody-drug conjugate datopotamab deruxtecan in patients with metastatic hormone receptor–positive breast cancer and triple-negative breast cancer.

The combination of gedatolisib and fulvestrant with or without palbociclib is under evaluation in the phase 3 VIKTORIA-1 trial for the treatment of patients with PIK3CA-mutated or wild-type hormone receptor–positive/HER2-negative breast cancer who have previously progressed on first-line therapy.

Nusayba Bagegni, MD, discusses updated efficacy and biomarker data from the phase 2 APT and ATEMPT trials in early-stage HER2-positive breast cancer.

Manali Bhave, MD, discusses the effect of emerging therapies on the treatment landscape for patients with HR-positive, HER2-negative or -low breast cancer, highlighted her stance on sequencing decisions for these patients, and expanded on the additional work being done to optimize treatment sequencing from a growing list of options.
