The incidence of primary malignant brain tumors is increasing, especially in the elderly, and metastatic disease to the central nervous system (CNS) occurs even more frequently (an incidence about 10 times that of primary brain tumors). In fact, estimates are that 20% to 40% of patients with systemic cancer will develop brain metastases. Primary and metastatic brain tumors are heterogeneous, with varied outcomes and management strategies. This marked heterogeneity means that prognostic features and treatment options must be carefully reviewed for each patient. As these guidelines note, the involvement of an interdisciplinary team is key in the appropriate management of these patients. Important updates to the guidelines include the addition of systemic chemotherapy as a salvage therapy treatment option for local recurrence and limited metastatic lesions and its deletion as an option for multiple metastatic lesions.
