Recent advancements in HER2-positive metastatic breast cancer treatments are reshaping patient outcomes.
Frequently Asked Questions (FAQ)
- Q1: What is HER2-positive metastatic breast cancer?
- A1: It is a subtype of breast cancer characterized by overexpression of the human epidermal growth factor receptor 2 (HER2), indicating a more aggressive disease progression.
- Q2: What are the latest targeted therapies?
- A2: New targeted therapies include tucatinib, neratinib, and antibody-drug conjugates like trastuzumab deruxtecan (DS-8201).
- Q3: How do these treatments work?
- A3: These therapies inhibit HER2 signaling pathways or deliver cytotoxic agents directly to HER2-positive cancer cells, enhancing treatment efficacy.
- Q4: What are the side effects of these therapies?
- A4: Side effects may include diarrhea, nausea, fatigue, and risk of heart problems; monitoring is essential.
- Q5: What is the role of immunotherapy?
- A5: Immunotherapy, including checkpoint inhibitors, is being explored as a potential treatment option to enhance the immune response against HER2-positive tumors.
