  • Research summary

    This is a multicenter, open-label, randomized phase II clinical trial for the chemotherapy-free treatment (trastuzumab and pertuzumab) of HER2-positive breast cancer using an FDG-PET (fluorodeoxglucose-positron emission tomography) response-adapted strategy.

    Significant antitumor activity of the dual HER2 blockade with trastuzumab and pertuzumab has been reported during neoadjuvant treatment (early stage, prior to the main treatment such as surgery).

    Non-invasive imaging tools such as 18F-FDG PET/CT, that could guide the response to this early stage therapy are of particular interest. Early metabolic evaluation using 18F-FDG PET/CT might help to recognize patients with an increased probability of a pathologic complete response (pCR) and an excellent outcome with a chemotherapy-free treatment strategy based on the dual HER2 blockade with trastuzumab and pertuzumab.

    This randomized, open-label phase II study will assess the efficacy of the combination of trastuzumab and pertuzumab, ± endocrine therapy according to hormone receptor (HR) status, as exclusive neoadjuvant and adjuvant treatment in patients with HER2-positive breast cancer through a FDG-PET response-adapted strategy.
