Totally, 150-200 patients with measurable/evaluable primary breast cancer are planned for inclusion within a period of two years time. For each imaging method, approximately 40-50 patients will be included. The study is designed to find early predictors of response by testing a set-up of several different molecular and imaging tools. In addition, for each method changes of patterns occurring during treatment will be compared to baseline findings and, in the case of functional imaging, standard imaging procedures.
