Brain MRI Surveillance Without Prophylactic Irradiation Improves Cognitive Outcomes in Small Cell Lung Cancer
Source Summary
The SWOG S1827 MAVERICK Phase III randomized trial found that small-cell lung cancer patients who received regular brain MRI surveillance without prophylactic cranial irradiation achieved significantly better cognitive failure-free survival, the trial's primary endpoint. Overall survival showed no apparent difference between the surveillance and standard treatment groups. Results were presented at the IASLC 2026 World Conference on Lung Cancer in Seoul, South Korea.
Why it matters
This trial demonstrates that brain MRI surveillance can preserve cognitive function in small-cell lung cancer patients while maintaining comparable overall survival, potentially changing standard treatment protocols.
