New research finds that adding carboplatin to paclitaxel and adjuvant chemotherapy shows no significant survival benefits in triple-negative breast cancer (TNBC).

Clairity Breast's FDA-approved AI platform revolutionizes breast cancer risk prediction, enhancing early detection and personalized prevention strategies.

Explore the complexities of managing toxicities in breast cancer treatments, including endocrine therapies, antibody drug conjugates, and immune checkpoint inhibitors.

APOBEC3 mutagenesis emerges as a key factor in breast cancer treatment resistance, offering new avenues for targeted therapies and predictive biomarkers.

In premenopausal women, denosumab significantly prevented bone loss and microarchitectural deterioration.

Combining olaparib with neoadjuvant chemotherapy enhances survival rates for early-stage gBRCAm triple-negative breast cancer, offering new hope for patients.

Abemaciclib and ribociclib have various risks and benefits in treating early breast cancer, highlighting the importance of patient-provider communication.

Pharmacists can educate patients on nonpharmacologic strategies that help improve survival outcomes.

Updates on April 30, 2025, introduce changes to treatment regimens, sequencing flexibility, febrile neutropenia risk assessments, and drug-specific safety and supportive care guidance.

Hyperglycemia is a common and significant adverse effect of PI3K and AKT inhibitors in hormone receptor-positive (HR+) breast cancer.

Study shows a significant decline in breast cancer mortality across multiple subtypes.

The combination yielded superior progression-free (PFS) survival compared with standard of care.

Breast cancer treatment is highly individualized and based on the stage, hormone receptor status, HER2 expression, and patient-specific factors.

Fatty acid metabolism plays a critical role in treatment responses.

Evolving breast cancer risk models and prevention methods are necessary to improve patient outcomes, according to Sagar Sardesai, MD.

Aromatase inhibitors were superior to tamoxifen in reducing risk of contralateral breast cancer.

The findings provide a deeper understanding of the mechanisms underlying breast cancer progression and treatment resistance.

Even when safe, oral supplement use may not be appropriate to use during cancer treatment or recovery.

Panelists discuss how when making antibody-drug conjugate (ADC) treatment decisions for patients with metastatic breast cancer (mBC), pharmacists primarily consider patient-specific factors such as biomarker status, prior therapies, disease burden, and comorbidities. ADCs are typically introduced after standard first-line treatments show inadequacy or in specific molecular subtypes that demonstrate strong responses to targeted therapy.

Panelists discuss how antibody-drug conjugates (ADCs) for breast cancer (BC) differ in their safety profiles, with trastuzumab deruxtecan (T-DXd) having notable interstitial lung disease risk, sacituzumab govitecan (SG) associated with neutropenia/diarrhea, and datopotamab deruxtecan (Dato-DXd) showing a relatively favorable safety profile but still requiring monitoring.

The authors’ findings show a greater decline in those treated with chemotherapy vs endocrine therapy.

New drugs and collaborative care may be key to overcoming trial closures, weak guidelines, and inefficiencies.

Sacituzumab govitecan improves outcomes but requires careful management of adverse effects.

Panelists discuss how HER2 testing optimization requires multisite sampling and quantitative assessment methods to account for intratumoral heterogeneity. Beyond HER2, biomarkers such as PI3K mutations, hormone receptor status, and tumor mutational burden can guide therapy selection for metastatic breast cancer (mBC), enabling more personalized treatment approaches.

Panelists discuss how antibody-drug conjugates (ADCs) show varying efficacy and adverse event (AE) profiles based on their payload potency, linker stability, and drug-to-antibody ratio. Cleavable linkers enable targeted drug release but may increase toxicity, while noncleavable designs offer better stability. Payload selection impacts both therapeutic index and AEs, with more potent warheads requiring careful optimization of targeting and release kinetics.

Panelists discuss how antibody-drug conjugates (ADCs) combine monoclonal antibodies with cytotoxic payloads, enabling precise targeting of breast cancer (BC) cells through specific antigen recognition. Upon binding, the ADC-antigen complex is internalized, releasing the toxic payload inside cancer cells while largely sparing healthy tissue. This targeted approach offers improved efficacy and reduces systemic toxicity compared with traditional chemotherapy's broad cytotoxic effects.

Panelists discuss how the National Comprehensive Cancer Network (NCCN) and American Society of Clinical Oncology (ASCO)/College of American Pathologists (CAP) guidelines for HER2-negative breast cancer (BC) have evolved to recognize HER2-low (IHC 1+  or 2+/ISH-negative) and HER2-ultra low (IHC 0) as distinct categories. These classifications, particularly HER2-low, guide eligibility for targeted therapies such as trastuzumab deruxtecan, expanding treatment options beyond traditional chemotherapy for previously categorized HER2-negative patients.

Using new treatment advances, traditional medications, genetic profiles, immunotherapies, and individualized plans enables providers to improve outcomes for patients with TPBC.

Black women have higher rates of triple-negative breast cancer (TNBC) incidence and mortality than the general US population. Despite this, they are underrepresented in TNBC clinical trials.
