[Management of brain metastases in 2022]

Brain metastases (BM) are a common occurrence of systemic cancers. Technical improvements in neuroimaging offer additional tools for an early detection of BM, to target them precisely and differentiate these lesions from other cerebral pathologies. The therapeutic tools have also evolved from neurosurgery and whole brain therapy to include stereotactic radiosurgery, targeted and immune therapies. Given the numerous treatment options available, a multidisciplinary approach is essential to offer the patient a personalized approach to optimize the sequence and combination of treatments to offer the best outcome possible. This article aims to review key elements of diagnosis, risk stratification and modern treatment paradigms in the diagnosis and management of BM.
