HER2 plays a critical role in breast cancer, particularly influencing treatment strategies for older women.

Q: What is HER2?

HER2 (human epidermal growth factor receptor 2) is a protein that can promote the growth of cancer cells. In some breast cancers, HER2 is overexpressed, which can lead to more aggressive forms of the disease.

Q: Why is HER2 status important in breast cancer?

HER2 status is vital as it determines the treatment options available for patients. HER2-positive cancers tend to respond differently to chemotherapy and targeted therapies compared to HER2-negative cancers.

Q: How does HER2 affect treatment options for older women?

• **Targeted Therapy:** HER2-positive cancers can be treated with targeted therapies such as trastuzumab (Herceptin) and pertuzumab (Perjeta), which are designed to specifically attack tumor cells that overexpress HER2.
• **Chemotherapy:** Older women with HER2-positive breast cancer may still receive chemotherapy, but studies show that they might benefit more from targeted therapies given their potential side effects from traditional chemotherapy.
• **Hormonal Therapy:** The presence of HER2 does not affect hormonal therapy options but may influence how other therapies are sequenced or combined.
• **Age Considerations:** The treatment approach may differ depending on the individual’s overall health, comorbidities, and life expectancy.

Q: What are the risks associated with HER2-targeted treatments in older women?

Older women may experience different side effects and risks. Cardiotoxicity is a potential risk associated with HER2-targeted therapies like trastuzumab. Thus, cardiac monitoring is crucial.

Q: Are there any guidelines for treating HER2-positive breast cancer in older women?

Major organizations like the American Society of Clinical Oncology (ASCO) provide guidelines that suggest personalized treatment plans that consider the patient’s age, health status, and HER2 status.

Q: How effective are HER2-targeted therapies in older women?

Recent studies show that HER2-targeted therapies have significantly improved survival rates even in older populations, indicating their effectiveness and the increased need for more tailored treatment approaches.
