Panelists discuss how emerging developments in HER2-positive (HER2+) breast cancer treatment, including novel antibody-drug conjugates, bispecific antibodies, and cytotoxic-sparing regimens for hormone receptor+ (HR+)/HER2+ disease, are creating exciting new options for patients.

Panelists discuss how they approach treatment beyond third-line therapy for HER2-positive (HER2+) metastatic breast cancer, considering factors such as prior therapies, residual toxicities, and patient preferences when selecting from multiple options.

Panelists discuss how they manage adverse effects of tucatinib-based therapy, particularly focusing on diarrhea and palmar-plantar erythrodysesthesia from capecitabine, with practical dosing strategies to improve tolerability.

Panelists discuss how the HER2CLIMB-02 and HER2CLIMB-05 trials might impact treatment sequencing, with particular interest in using tucatinib earlier in treatment to potentially prevent brain metastases.

Panelists discuss how National Comprehensive Cancer Network (NCCN) guidelines inform third-line treatment options for HER2-positive (HER2+) metastatic breast cancer, with particular focus on the HER2CLIMB regimen (tucatinib, capecitabine, and trastuzumab) for patients with brain metastases.

Panelists discuss how they would approach multiple brain metastases at initial metastatic diagnosis, debating the use of stereotactic radiosurgery vs systemic therapy with agents that cross the blood-brain barrier.
