Prupose:
Neoadjuvant stereotactic radiotherapy (NaSRT) represents a promising approach in managing brain metastases, potentially offering advantages over traditional postoperative radiotherapy.
Methods:
We conducted a systematic review of the ClinicalTrials.gov website for studies investigating neoadjuvant radiotherapy for brain metastases, either as a single arm or in comparison with adjuvant radiotherapy.
Results:
This review analyzes 18 registered clinical trials investigating NaSRT, focusing on variations in trial design, inclusion criteria, and endpoints being explored. These trials aim to assess outcomes such as local control, systemic therapy integration, and the reduction of complications, including leptomeningeal disease and radiation necrosis. The diversity of methodologies underscores the need for standardized protocols to enhance comparability and future applicability.
Conclusion:
By highlighting current trends and research gaps, this review provides insights into the evolving role of NaSRT, emphasizing its potential to influence treatment strategies and improve patient outcomes.
