Early findings from the DEBBRAH study suggest that fam-trastuzumab deruxtecan-nxki shows potential in treating patients with advanced HER2-positive, HER2-low breast cancer, including those with leptomeningeal carcinomatosis.

Datopotamab deruxtecan demonstrated a statistically significant and clinically meaningful improvement in progression-free survival compared with chemotherapy in patients with previously treated, hormone receptor-positive/HER2-negative inoperable or metastatic breast cancer.

The RELIEVE study looked at real-world patients receiving trastuzumab deruxtecan based on HER2 expression status and time to next treatment including in those whose HER2 status changed during course of treatment.

Naomi Dempsey, MD, discusses her poster presented at the 2023 San Antonio Breast Cancer Symposium analyzing the correlation of the Breast Cancer Index and patient risk factors.

Accurately stratifying hormone receptor–positive, HER2-negative breast cancer using BluePrint and MammaPrint assays demonstrated comparable 3-year recurrence-free survival rates between Black and White patients despite disparities in the distribution of molecular subtypes.

The introduction of tucatinib to ado-trastuzumab emtansine significantly improved progression-free survival vs placebo plus T-DM1 in patients with previously treated HER2-positive metastatic breast cancer.

Maintenance pembrolizumab plus olaparib did not improve progression-free or overall survival in patients with locally recurrent inoperable or metastatic triple-negative breast cancer.

Adding pembrolizumab to neoadjuvant chemotherapy followed by adjuvant pembrolizumab with endocrine therapy demonstrated improvements pathologic complete responses in key subsets of patients with early-stage, high-risk, estrogen receptor–positive/HER2-negative breast cancer.

Patients with hormone receptor-positive, HER2-negative, node-positive, high-risk early breast cancer given abemaciclib for 2 years in addition to endocrine therapy demonstrated an association between ctDNA positivity and disease recurrence.

Patient-reported outcomes of the CAPItello-291 study of capivasertib plus fulvestrant showed a positive benefit-risk profile for the combination in patients with HR-positive, HER2-negative advanced breast cancer.

Senthil Damodaran, MD, PhD, discusses data from a phase 2 trial of futibatinib in patients with metastatic HR-positive/HER2-negative breast cancer with FGFR1 amplifications.

Prospective models show a drop in the cost of running sentinel lymph node assessments when artificial intelligence is used.

Adding ribociclib to endocrine therapy shows efficacy and tolerability for those with hormone receptor–positive, HER2-negative advanced breast cancer, even in older patients.

Adam Brufsky, MD, PhD, FACP, discusses the real-world efficacy of letrozole in combination with palbociclib as treatment of patients with estrogen receptor-positive, HER2-negative, advanced breast cancer, based on race and ethnicity.

Survival advantage was shown in a phase 3 study of neoadjuvant chemotherapy/carboplatin in patient with triple negative breast cancer.

Improvement in progression-free and overall survival was shown with sacituzumab govitecan in the phase 3 TROPiCS-02 trial.

Longer follow-up in the phase 3 STIC CTC trial substantiates that the CTC-based choice is safe in patients with metastatic breast cancer, according to investigators.

Treatment with various camizestrant monotherapy doses lead to survival benefit compared with fulvestrant in a post-menopausal patient population diagnosed with estrogen receptor–positive, HER2-negative advanced breast cancer.

The combination of palbociclib and fulvestrant beyond progression on prior CDK4/6 inhibitor did not show significant improvements in progression-free survival compared with fulvestrant alone in ER-positive/HER2-negative breast cancer.

Maryam Lustberg, MD, MPH, explains how the HER2 low session during the 2022 San Antonio Breast Cancer Symposium.

Results from the VERITAC trial presented at the 2022 San Antonio Breast Cancer Symposium showed that ARV-471 monotherapy may be active in ER-positive/HER2-negative locally advanced/metastatic breast cancer.

Findings from the phase 3 CAPItello-291 trial show that the combination of capivasertib plus fulvestrant achieved improvement in progression-free survival among patients with hormone-receptor–positive/HER2-negative advanced breast cancer.

Findings from the HER2CLIMB clinical trial of tucatinib combined with trastuzumab and capecitabine verified the safety of the regimen in patients with HER2-positive metastatic breast cancer.

The use of trastuzumab deruxtecan in the neoadjuvant setting showed promising responses in patients with early-stage breast cancer.

Patients with advanced HER2-positive breast cancer had better progression-free and overall survival outcomes when given trastuzumab deruxtecan versus capecitabin-based treatment.

According to Ruth O'Regan, MD, BCI is the first genomic assay to demonstrate benefit from ovarian suppression.

Among premenopausal patients, the addition of everolimus to endocrine therapy improved iDFS and OS, which is hypothesis generating, said Mariana Chavez-MacGregor, MD.

The data from 2 years post primary efficacy analysis of monarchE study showed that adjuvant abemaciclib plus endocrine therapy improves invasive disease-free survival.

Residual disease after neoadjuvant chemotherapy tumor microenvironment of metastasis doorway density is higher in Black women, potentially explaining poorer outcomes.
