Recent advancements in treatments for HER2-positive breast cancer have shown promise, offering new hope for patients.

Q: What is HER2-positive breast cancer?

A: HER2-positive breast cancer is a subtype of breast cancer characterized by the overexpression of the human epidermal growth factor receptor 2 (HER2) protein. This leads to more aggressive tumor growth and poorer prognosis compared to HER2-negative subtypes.

Q: What are the latest breakthroughs in treatment?

• Targeted Therapies: Recent studies have explored combination therapies that include newer agents like tucatinib and neratinib alongside established drugs like trastuzumab.
• Dual HER2 Blockade: Research indicates that dual blockade using trastuzumab and pertuzumab yields improved survival outcomes.
• Immunotherapy: The use of checkpoint inhibitors in combination with HER2-targeted therapies is being investigated to enhance the immune response against tumors.
• Antibody-Drug Conjugates (ADCs): New ADCs such as trastuzumab deruxtecan have shown impressive efficacy in heavily pre-treated HER2-positive breast cancer patients.
• Neoadjuvant Approach: Studies are looking into the use of HER2-targeted therapies before surgery to reduce tumor size and improve surgical outcomes.

Q: How effective are these new treatments?

A: Clinical trials have demonstrated that new treatments can significantly improve progression-free survival and overall survival rates. For example, studies on trastuzumab deruxtecan have indicated response rates up to 60% in specific populations.
