Early breast cancer with human epidermal growth factor receptor 2 (HER2 [EGFR2]) positivity has a better chance of recovery due to the potential of targeted adjuvant and neoadjuvant anti-HER2 treatments. Nevertheless, 25% of patients who still have the disease, despite the treatment, remain mostly in the form of distant metastases.
Therefore, it is sensible for patients at risk to enhance anti-HER2 treatment for early HER2 positive cancer. One option is prolonged adjuvant therapy with neratinib.
