Primary endpoints: Objective response (OR) characterized by conventional radiological and functional imaging procedures and biological tumour markers at an early point of treatment with epirubicin + docetaxel and effects of addition of bevacizumab as reflected by these procedures. Early functional and biological changes signalling pathological complete response (pCR). Secondary endpoints: Secondary endpoints: Morphological and biological changes of tumours exposed for cytotoxic and targeted treatment. Disease-free survival. Safety.
