Predictive value of early DCE and DSC perfusion MRI parameters for midterm clinical outcomes in lung cancer brain metastases treated with stereotactic radiosurgery
To assess the predictive value of early post-SRS DCE- and DSC-MRI parameters to distinguish SRS responders and non-responders at midterm follow-up, which is crucial for optimizing patient management.
Key Findings:
Early alterations in DCE and DSC MRI parameters may correlate with midterm tumor local control, suggesting a need for early intervention.
DCE-MRI parameters like K-trans, Ve, and Vp provide insights into vascular permeability, which could guide treatment decisions.
DSC-MRI nCBV serves as a surrogate marker for tumor-induced angiogenesis, indicating potential for targeted therapies.
Interpretation:
The study suggests that early imaging biomarkers can help predict midterm treatment outcomes in lung cancer brain metastases treated with SRS, potentially influencing clinical decision-making.
Limitations:
Retrospective design may introduce selection bias, limiting the reliability of the findings.
Limited sample size and single-center study may affect generalizability, suggesting the need for multi-center trials.
Conclusion:
Early DCE and DSC MRI parameters could serve as valuable prognostic tools for assessing treatment response in lung cancer brain metastases post-SRS, emphasizing the need for integration into clinical practice.
