In this episode, Two Onc Docs review the current management of metastatic breast cancer, emphasizing treatment strategies across molecular subtypes.
Two Onc Docs, hosted by Samantha A. Armstrong, MD, and Karine Tawagi, MD, is a podcast dedicated to providing current and future oncologists and hematologists with the knowledge they need to ace their boards and deliver quality patient care. Dr Armstrong is a hematologist/oncologist and assistant professor of clinical medicine at Indiana University Health in Indianapolis. Dr Tawagi is a hematologist/oncologist and assistant professor of clinical medicine at the University of Illinois in Chicago.
In this episode, OncLive On Air® partnered with Two Onc Docs to feature a comprehensive review of the current management of metastatic breast cancer, emphasizing evidence-based treatment strategies across molecular subtypes, toxicity management, and patient-centered care. Drs Armstrong and Tawagi discussed that the primary goals of metastatic breast cancer therapy include prolonging survival, controlling symptoms, minimizing toxicity, improving quality of life, and incorporating patients’ goals and preferences into care decisions. Their discussion also highlighted the importance of recognizing when transitioning to best supportive care is most appropriate.
For estrogen receptor–positive metastatic breast cancer, they noted that first-line therapy includes an aromatase inhibitor or fulvestrant (Faslodex) combined with a CDK4/6 inhibitor, with ovarian function suppression for premenopausal patients. PARP inhibitors are recommended for patients with BRCA1/2-positive disease. In visceral crisis, chemotherapy remains the category 1 recommendation. Second-line treatment options include therapies guided by repeat molecular testing. fam-trastuzumab deruxtecan-nxki (T-DXd; Enhertu) is approved for patients with HER2-low disease. For HER2-positive metastatic breast cancer, first-line treatment consists of a taxane plus pertuzumab (Perjeta) and trastuzumab (Herceptin), followed by T-DXd in the second-line setting. For triple-negative metastatic breast cancer, therapy depends on PD-L1 status.
The episode concluded by underscoring the role of bone-protective agents such as zoledronic acid, pamidronate, or denosumab (with dental clearance to prevent osteonecrosis). Key takeaways emphasize tailoring therapy to molecular subtype, recognizing drug-specific toxicities, and prioritizing patient-centered decision-making in the management of metastatic breast cancer.
