Abstract: Objective To summarize the latest research advances in precision detection, biomarkers, and treatment strategies for breast cancer leptomeningeal metastasis (BCLM) in order to provide references for improving the clinical efficacy and prognosis of patients. Methods An in-depth analysis of the mechanisms underlying BCLM was conducted based on the molecular diagnostic techniques, prognostic biomarkers, as well as therapeutic strategies. Current challenges to diagnostic approaches and treatment strategies were also studied. Results Based on advancements in novel detection technologies, individualized treatment strategies guided by biomarkers promised wide applications. Furthermore, new targeted drugs and delivery technologies offered more opportunities to improve patients’ prognosis. Conclusion The clinical management of BCLM should integrate precision testing, biomarker-guided approaches, and multimodal treatment strategies. High-quality clinical studies are essential to optimizing therapeutic frameworks and prolonging patients’ survival.
