CHEMO- AND TARGET THERAPY OF PATIENTS WITH BREAST CANCER WITH METASTATIC BRAIN LESIONS

Results of studies performed have shown high efficiency of drug therapy for treatment of patients with breast cancer (BC) with brain metastases. The best results regarding survival rate have been achieved for treatment of BC patients with brain metastases and HER2 hyperexpression. At present, studies are performed regarding examination of new anticancer drugs and their use in combination with radiotherapy for treatment of BC patients with brain metastases. It is necessary to perform studies of efficiency of various schemes of drug therapy depending on biological properties of the primary tumor. The issue of sequence of application of drug therapy and radiotherapy for metastatic brain lesions also remains actual.
