Among the solid tumors breast cancer is one of the few types of cancers sensitive to different systemic treatment reginJens both with respect to endocrine- and chemotherapy. Both treatment modalities are nowadays standard practice in the treatment of breast cancer, either to achieve cure, or prolongation of (relapse-free) survival in the adjuvant setting, or to palliate metastatic disease. The efficacy of the different forms of systemic treatment is dependent on patients- and tumor characteristics.
