Therapeutic options for brain metastases

Abstract

Brain metastases are common in cancer patients, especially in lung cancer, breast cancer and melanoma and represent a therapeutic challenge. Established local therapeutic procedures include neurosurgical resection, stereotactic irradiation and whole brain radiotherapy; however, for selected patients novel targeted therapies with documented activity against brain metastases are emerging. These include v-raf murine sarcoma viral oncogene homolog B (BRAF) inhibitors, the anticytotoxic T lymphocyte-associated protein 4 (CTL4A) antibodies ipilimumab in melanoma, HER2 antagonists in breast cancer and epidermal growth factor receptor (EGFR) and anaplastic lymphoma kinase (ALK) inhibitors in non-small cell lung cancer. Therefore, the modern management of patients with brain metastases should be performed in an interdisciplinary setting and under consideration of relevant molecular markers to facilitate optimal patient outcome.
