Study confirms everolimus can overcome trastuzumab resistance in HER-2 positive early breast cancer
Date:5/2/2013

h it quite unequivocally shows that the addition of everolimus to trastuzumab leads to an increase in clinical responses in Her-2/neu overexpressing breast cancer, as compared to trastuzumab alone," he said.

"Thus, it not only adds to clinical possibilities which can be offered to patients, but also further explains the modalities of molecularly directed therapeutic manipulation in breast cancer," said Prof Zielinski. However, the limited pathologic response constitutes a clear drawback from clinical observations.

"Nevertheless this study contributes to our assumptions on the application of molecularly targeted therapies in breast cancer in particular and in malignancies in general. It also helps to move to an era where the targeting of multiple molecular structures (like here with trastuzumab and everolimus) leads to ameliorated results by 'hitting' multiple growth-regulating mechanisms, but also avoiding treatment resistance which continues to be a major challenge in cancer treatment."
