Early HER2-Positive Breast Cancer: Current Treatment and Novel Approaches
Background: Trastuzumab significantly improves outcomes in early HER2-positive breast cancer, irrespectively of any prognostic or predictive factors. Unfortunately, about a quarter of patients receiving neoadjuvant trastuzumab experience disease recurrence, revealing the unquestionable need for further improvement of treatment outcomes. Summary: Adding HER2 blockade to adjuvant trastuzumab with pertuzumab and neratinib improves invasive disease-free survival (IDFS), particularly for those at highest risk of recurrence. A shift toward a neoadjuvant strategy for patients with a higher risk of recurrence could result in further treatment optimization. For patients without a pathological complete response (pCR) after the neoadjuvant part of the therapy, a switch to adjuvant trastuzumab emtansine significantly improves IDFS and distant recurrence-free survival and shows a trend towards improved overall survival (OS). On the other hand, for low-risk patients, chemotherapy deescalation should be strongly considered with the use of trastuzumab monotherapy as an anti-HER2 backbone. Key Messages: Neoadjuvant therapy should be offered for a significant proportion of HER2- positive early breast cancer patients with a higher risk of recurrence. Postneoadjuvant treatment should be tailored according to the initial stage of disease and the response to neoadjuvant treatment.
