Breast Cancer

Mark Pegram, MD, discussed the highlights from ASCO 2022, regarding antibody drug conjugates.

The phase 2 CTMX-2009-002 trial met its primary end point of confirmed objective response greater than 10% for patients with hormone receptor–positive, HER2–non-amplified breast cancer being treated with praluzatamab ravtansine.

Steven J. Chmura, MD, PhD, discussed recent findings from the phase 2R/3 NRG-BR002 trial in patients with newly diagnosed oligometastatic breast cancer.

Paolo Tarantino, MD, and Sara M. Tolaney, MD, MPH, spoke with CancerNetwork® about highlights from 2022 ASCO in breast cancer research.

Mark Pegram, MD, spoke about predictive and prognostic factors used to determine which patients with early-stage hormone receptor–positive breast cancer benefit from extended vs standard adjuvant endocrine therapy.

Mark Pegram, MD, spoke about using the Breast Cancer Index and Clinical Treatment Score post-5 years to determine outcomes for patients with early-stage hormone receptor–positive breast cancer treated with adjuvant endocrine therapy.

Patients with hormone receptor–positive, ERBB2-negative high-risk early breast cancer who received neoadjuvant chemotherapy and adjuvant abemaciclib plus endocrine therapy experienced invasive disease-free survival and distant relapse-free survival benefit vs those with adjuvant endocrine therapy alone.

After identifying several factors independently associated with the risk of breast cancer–related lymphedema following axillary lymph node dissection, investigators recommend further studies to examine biologic mechanisms behind racial and ethnic disparities within this space.

Steven J. Chmura, MD, PhD, spoke about interesting findings from a phase 2R/3 trial of patients with newly oligometastatic breast cancer who were given standard of care systemic treatment with or without stereotactic body radiotherapy and/or surgical resection.

Independent factors such as the integrated clinical radiomics model and 18F-FDG PET/CT radiomics signature may be predictive of progression-free survival in breast cancer.

Hope S. Rugo, MD, FASCO, spoke about future analyses of the phase 3 TROPiCS-02 trial that examined sacituzumab govitecan vs physicians’ choice chemotherapy in patients with hormone receptor–positive, HER2-negative advanced breast cancer.

Hope S. Rugo, MD, spoke about results of the phase 3 TROPiCS-02 trial examining sacituzumab govitecan vs physicians’ choice chemotherapy for patients with hormone receptor–positive, HER2-negative advanced breast cancer presented at ASCO 2022.

Dose reductions of ribociclib administered during the phase 2 MONALEESA-2 trial did not have an impact on overall survival for patients with hormone receptor–positive, HER2-negative advanced breast cancer.

Radiotherapy can be avoided after surgery in certain patients with low-grade luminal A breast cancer who have low Ki67 expression and no positive lymph nodes, according to data from 2022 ASCO.

Patients with acquired ESR1 mutations after disease progression and post-treatment for locally advanced or metastatic estrogen receptor–positive, HER2-negative breast cancer may benefit from treatment with lasofoxifene in combination with abemaciclib.

Results of a matching-adjusted indirect comparison study showed that patients with HR-positive/HER2–negative advanced breast cancer treated with ribociclib and an aromatase inhibitor were more likely to have better symptom-related quality of life than patients who received abemaciclib and an aromatase inhibitor.

Factors associated with early discontinuation of adjuvant abemaciclib for hormone receptor—positive, HER2-negative, node-positive high-risk early breast cancer inform future treatment monitoring.

Alpelisib combined with fulvestrant represents a viable treatment option for patients with hormone receptor–positive, HER2-negative advanced breast cancer, regardless of mutation status.

The phase 3 DESTINY-Breast04 trial using fam-trastuzumab deruxtecan-nxki showed a reduction in the risk of disease recurrence or death for patients with HER2-low, hormone receptor–positive metastatic breast cancer.

Patritumab deruxtecan induced positive efficacy, according to the phase 1/2 U31402-J101 trial in patients with HER3-expressing metastatic breast cancer or metastatic triple-negative breast cancer.

At 2022 ASCO, final survival data from the phase 3 PALOMA-2 trial confirmed similar survival between palbociclib plus letrozole and letrozole alone.

Ribociclib plus endocrine therapy for hormone receptor–positive, HER2-negative advanced breast cancer following progression on a CDK4/6 inhibitor bests matched placebo.

Compared with chemotherapy, sacituzumab govitecan led to better progression-free survival outcomes in patients with hormone receptor–positive, HER2-negative breast cancer.

European patients with locally advanced or early-stage triple-negative breast cancer at high risk of recurrence can now receive treatment with neoadjuvant pembrolizumab and chemotherapy, as well as pembrolizumab monotherapy post surgery following its approval by the European Commission.

A Black patient with metastatic breast cancer explained that the results of the survey show that more work must be done by all stakeholders to increase the participation in clinical trials to accurately assess treatments in diversified populations.
