What this trial is about
This is a single centre Window-of-Opportunity trial investigating the efficacy and feasibility of short term imatinib in patients with newly diagnosed triple negative breast cancer (TNBC) planned for surgery, with tumours ≥ 15 mm, any status in the axilla when neoadjuvant treatment not is considered as an option. The primary aim is to determine the proportion of patients that converts to estrogen receptor (ER) positive breast cancer in the removed breast cancer tissue at surgery.
