Abstract

Chen et al explored clinicopathological features and prognostic factors, revealing advanced tumor stage, lung metastases, HER-2 overexpression, and triple-negative status as key contributors. Recent research connects astrocytes' role in brain metastasis with signaling pathways and the impact of Trastuzumab on HER-2 tumor survival. Factors such as positive HER2 status, lack of estrogen receptor expression, and liver metastasis are identified as additional risk factors. The routine use of magnetic resonance imaging, insights into gene mutations associated with metastasis, and the role of radiotherapy, including prophylaxis possibilities, is controversial in clinical practice. Understanding these risk factors in a multidisciplinary collaboration is precise for local treatments and targeted therapies, particularly for HER2+ tumors, impacting directly on longer survival.

Keywords: Brain metastases; Breast cancer; Clinicopathological features; High-risk factors

Core Tip: Based on an institutional analysis of risk factors to develop brain metastases in a setting of breast cancer patients, we have conducted a brief review of the literature on the known risk factors as well as the various strategies that could contribute to improving disease control and survival prospects for these patients.
