The panel reviews a 58-year-old patient with HR-positive, HER2-negative metastatic breast cancer progressing after endocrine therapy plus CDK4/6 inhibitor treatment. The patient has hepatic and bone metastases with radiographic and symptomatic progression, ECOG performance status 1, controlled hypertension, and mild dry eye syndrome. She prioritizes maintaining professional activity and independence.

Dr. Iyengar addresses common patient fears about vision loss, noting this represents a primary concern when discussing ocular toxicity. Dr. Sunshine provides reassurance that these represent reversible changes with appropriate monitoring and early intervention, emphasizing the importance of early detection through regular examinations.

Dr. Sunshine provides ophthalmologic perspective on Dato-DXd's unique ocular surface events, representing a new toxicity profile for breast oncology practitioners. The management approach begins with baseline patient education and ophthalmologic examination, establishing foundation for both patient awareness and professional monitoring.

Dr. Nunnery discusses ASCENT-07, which moved SG earlier in the treatment sequence for HR-positive disease, allowing patients progressing on endocrine therapy to receive the ADC immediately rather than requiring intervening chemotherapy. Surprisingly, this frontline comparison against standard chemotherapy yielded negative results without statistically significant PFS improvement.

Panelists discuss the adverse effects experienced by a patient undergoing treatment with capecitabine (Xeloda), trastuzumab (Herceptin), and tucatinib (Tukysa), along with the strategies employed to manage those adverse effects, while also addressing patient follow-up procedures, including the frequency of visits, typical labs and imaging ordered, concerning symptoms and lab results, and the outcomes of the patient's most recent follow-up appointment.

Panelists discuss how patients are prepared for treatment, the adverse effects associated with different agents and combination regimens that they educate patients about, the process of administering treatment for HER2+ breast cancer, and the overall approach to monitoring and managing adverse effects throughout the treatment journey.

Panelists discuss key data from the HER2CLIMB study, which evaluates the efficacy of tucatinib (Tukysa) in combination with trastuzumab (Herceptin) and capecitabine (Xeloda) for patients with advanced HER2+ breast cancer, highlighting outcomes across patient subgroups and the clinical significance of findings related to patients with measurable baseline intracranial disease.

Panelists discuss a high-level overview of systemic therapies for advanced HER2+ breast cancer, outlining the roles of HER2-targeted monoclonal antibodies, tyrosine kinase inhibitors (TKIs), and antibody-drug conjugates (ADCs) in treatment, as well as treatment strategies for patients with brain metastases. They also explore the shared decision-making process that informed the recommendation of the HER2CLIMB regimen.
