43rd Annual Miami Breast Cancer Conference® - Abstracts

PREDICT II is a prospective 30-site observational registry enrolling 3000 women with DCIS to evaluate how a 7-gene biosignature (DCISionRT) impacts treatment recommendations for surgery, radiation, and hormonal therapy.

In this randomized trial, adding a pictorial COPE photo guide to standard verbal counseling for breast cancer patients receiving adjuvant RT led to the only statistically significant improvement in post-treatment skin change scores, with modest non-significant trends toward reduced anxiety.

This narrative review summarizes existing literature and clinical trial data on metastasis-directed and locoregional therapy for oligometastatic and oligoprogressive metastatic breast cancer, highlighting special scenarios where MDT may improve outcomes.

A streamlined clinical research team workflow at a Columbia University–affiliated community hospital achieved 5% to 8% annual trial enrollment, surpassing the Commission on Cancer benchmark and earning a National Cancer Institute Silver Award.

Qualitative interviews with 43 patients on capivasertib plus fulvestrant found the 4-on/3-off dosing schedule broadly acceptable, while identifying gaps in hyperglycemia recognition and willingness to use supportive medications.

This 13-case pictorial review from the University of Rochester Medical Center illustrates the variable mammography, ultrasound, and MRI presentations of pleomorphic invasive lobular carcinoma to support timely interdisciplinary diagnosis.

This pictorial case series of 5 intramammary spindle-cell lesions demonstrates characteristics that support confident benign diagnosis after biopsy without surgical excision.

This prospective study found that diffuse optical spectroscopy identified elevated collagen as a significant biomarker for breast cancer malignancy, supporting further investigation of DOS as a noninvasive complement to biopsy.

Using spatial proteomics and nanomechanical profiling across two clinical cohorts, investigators identified hypoxia-driven epithelial-to-mesenchymal transition as a biological signature linking aggressive biomechanical phenotypes to poor breast cancer outcomes.

A theory-driven paper planner combined with a digital AI companion demonstrated high acceptability and improved treatment confidence among patients with metastatic TNBC initiating ADC therapy.

In this Florida Cancer Data System mediation analysis, racialized economic segregation and insurance disadvantage explained 29% of the racial disparity in advanced breast cancer stage at diagnosis between Black and White women.

In this Florida Cancer Data System analysis, structural racism and health insurance disadvantage together mediated nearly 8% of the racial disparity in TNBC between Black and White women.

This retrospective claims analysis found neutropenia carried substantial economic burden in HR+/HER2– and triple-negative mBC, with the highest neutropenia-related costs seen during sacituzumab govitecan regimens.

This review of monarchE and TRADE data demonstrates that abemaciclib dose modifications manage treatment-related adverse events without compromising efficacy in high-risk HR+, HER2− early breast cancer.

This descriptive systematic review of 14 studies found diagnostic delay in PABC was common and multifactorial, driven by both patient- and provider-related factors including symptom misattribution to pregnancy.

This phase 1/2 trial assessed HER2 BATs combined with pembrolizumab in metastatic breast cancer, finding the regimen safe and well tolerated with stable disease as the best response in 17 evaluable patients.

This prospective, single-arm observational trial examines whether aromatase inhibitor therapy in postmenopausal women with HR-positive breast cancer adversely affects cardiorespiratory fitness, skeletal muscle function, and immunosenescence.

This randomized multicenter pilot trial assesses feasibility of the THRIVE Wellness Program, a 6-week lifestyle intervention for young breast cancer survivors aged 40 years or younger.

Survey of safety-net breast cancer patients links stronger faith to greater trust in doctors, especially among Black and lower-income groups.

Explore how breast cancer stem cell plasticity, epigenetic reprogramming, and single-cell insights drive therapy resistance, revealing new targets to improve durable responses.

Explore how newer HER2 therapies and anthracycline-sparing regimens cut breast cancer heart damage, with monitoring and cardioprotective drugs.

Real-world study shows T-DXd benefits older metastatic breast cancer patients, but higher ILD risk and toxicity-driven discontinuation demand close monitoring, especially in octogenarians.

Does infusion timing matter in TNBC? Early-day pembrolizumab may boost pCR and cut recurrences, prompting new scheduling questions.

Clonal blood mutations common in breast cancer may sharply raise heart failure risk after anthracyclines, urging better screening and personalized cardio-oncology care.

Explore how ADCs reshape breast cancer care, with practical sequencing strategies across subtypes and guideline-based toxicity management for ILD, neutropenia, and GI effects.

Real-world data show most first-line mTNBC patients are immunotherapy-ineligible, use chemotherapy, and face poorer survival, underscoring major unmet treatment needs.

T-DXd demonstrated a real-world overall response rate of 56.3%, median rwPFS of 7.4 months, and 12-month OS of 62% in patients with HER2-low metastatic breast cancer treated across US community oncology settings.

In a real-world cohort of 300 patients with HER2-low metastatic breast cancer, T-DXd demonstrated a safety profile consistent with DESTINY-Breast04 in community oncology settings, with ILD/pneumonitis in 10% and toxicity-related discontinuation in 15%.

Zovegalisib plus fulvestrant demonstrated an objective response rate of 38.7% and a median progression-free survival of 10.3 months in PIK3CA-mutant HR+/HER2– advanced breast cancer in the ReDiscover trial.

ctDNA-based next-generation sequencing in 236 patients with advanced breast cancer revealed frequent PIK3CA, TP53, and ESR1 mutations, highlighting key mechanisms of endocrine resistance with implications for targeted therapy selection.
