Abstract:
Brain metastases (BMs) are responsible for decline in neurological function, reduction in overall quality of life, and mortality from recurrent or untreatable lesions. Advances in diagnostics and imaging have led to increased detection of central nervous system (CNS) metastases in patients with progressive cancers. Improved control of extracranial systemic disease, and the limited ability of current therapeutics to cross the blood-brain barrier (BBB) also contribute to the increase in incidence of brain metastases, as tumor cells seek refuge in the brain. Surgery, chemotherapy, and/or radiation (whole-brain radiation therapy and stereotactic radiation surgery [WBRT/SRS]) are a clinically established treatment paradigm for patients with brain metastases. With the advent of genetic and molecular characterization of tumors and their immune microenvironment, clinical trials seek to include targeted drugs into the therapeutic regimen for eligible patients. Several challenges, like treatment of multiple CNS lesions, superior uptake of chemotherapy into the brain, and trials with multidisciplinary approaches, are now being clinically addressed.
Insights
Brain metastases (BMs) impact neurological function and survival. Advances in detection and targeted therapies are improving treatment for these central nervous system lesions.
Area of Science:
- Neuro-oncology
- Cancer Metastasis
Background:
- Brain metastases (BMs) significantly impair neurological function, quality of life, and survival.
- Increased detection of central nervous system (CNS) metastases is linked to advances in diagnostics and improved systemic cancer control.
- Tumor cells' ability to utilize the brain as a sanctuary site contributes to the rising incidence of BMs.
Purpose of the Study:
- To review the current landscape of brain metastases management.
- To highlight the challenges and advancements in treating CNS metastases.
- To discuss the integration of targeted therapies and multidisciplinary approaches.
Main Methods:
- Literature review of diagnostic and therapeutic strategies for brain metastases.
- Analysis of established treatments including surgery, chemotherapy, whole-brain radiation therapy (WBRT), and stereotactic radiation surgery (SRS).
- Exploration of emerging clinical trials incorporating molecular characterization and targeted agents.
Main Results:
- Enhanced diagnostic tools improve the detection rates of BMs.
- Current therapeutic paradigms involve surgery, radiation, and chemotherapy, with limitations in blood-brain barrier penetration.
- Emerging strategies focus on targeted therapies and multidisciplinary care to address challenges like multiple CNS lesions.
Conclusions:
- The management of brain metastases is evolving with improved detection and novel therapeutic strategies.
- Targeted therapies, informed by tumor molecular profiling, show promise for eligible patients.
- Multidisciplinary approaches are crucial for optimizing outcomes in patients with CNS metastases.
