| Summary: | The dissemination of malignant cells to the brain is a late-stage complication of cancer, leading to significant morbidity and mortality. Brain metastases (BM) affect 20–30% of cancer patients, primarily originating from lung cancer, breast cancer, and melanoma. Despite advances in molecular-targeted therapies, brain metastatic disease remains incurable, with a poor median survival of ≤12 months if left untreated. The lack of therapeutic efficacy is mainly attributed to the presence of the blood–brain barrier (BBB) and genetic differences between BM and their primary tumors. Previously published data have identified potential driver mutations of BM. However, the mechanisms underlying brain cancer dissemination remain unknown. Recent studies emphasize the pivotal role of metabolic adaptations in supporting the metastatic process, particularly in the nutrient-poor microenvironment characteristic of the brain. Understanding the interplay between metabolism and genetic alterations associated with brain metastatic disease could unveil novel therapeutic targets that are more effective in treating patients. This review focuses on relevant metabolic pathways in cancer, particularly brain cancer dissemination, while also presenting information on current preclinical models of BM, relevant clinical trials, and preclinical studies targeting metabolic reprogramming, providing an overview for advancing therapeutic strategies in BM. |
