All the main fields of breast cancer research and treatment were covered. This report will focus on the most relevant advancements in the pharmacotherapy of breast cancer. The selected presentations have been grouped together in separate sections, including the fields of prevention, early disease and advanced disease. The most promising data from translational research have also been included, with particular regard to those who will most likely influence the management of breast cancer patients in the future.
