Radiation zaps lingering brain tumors in lung cancer patients
NCT ID NCT06020066
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tests whether adding precise radiation (stereotactic radiosurgery) to standard drug therapy can better control brain metastases in people with non-small cell lung cancer. Participants have brain tumors that remain after 3-6 months of a targeted drug. The goal is to see if the combination delays cancer progression and improves survival.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- stereotactic radiotherapy (precise radiation beams)
- What this could lead to
- If successful, this approach could help control brain metastases in lung cancer patients, potentially delaying disease progression and improving survival without needing stronger drugs.
- What could go wrong
- This is a Phase 2 trial with 202 participants, so results are still preliminary. The added radiation may cause side effects like brain swelling or fatigue, and it may not work for everyone.

Inclusion Criteria: * Pathologically confirmed non-small cell lung cancer; * Clinical stage IV (AJCC, 8th edition, 2017); * EGFR mutations: EGFR L858R, EGFR exon 19 deletion; * Age ≥18 years; * KPS score ≥70; * Brain metastasis at the time of diagnosis; * Complete baseline imaging assessment of metastatic lesions, including enhanced MRI for brain; * Receiving first-line treatment with third-generation EGFR inhibitors; * After 3-6 months of third-generation EGFR inhibitor treatment, imaging review indicates no progression of extracranial lesions, and brain lesions are evaluated by thin-layer (1mm layer) enhanced MRI, meeting the following criteria: * No more than 10 remaining brain lesions; * The maximum diameter of the remaining brain lesions does not exceed 3cm; * At least one remaining brain lesion has a diameter greater than 5mm; * After evaluation by the researcher, all remaining brain lesions are suitable for stereotactic radiotherapy. * Patient informed consent. Exclusion Criteria: * Poor compliance with the study protocol in the investigator's opinion; * Patients withdrew their informed consent and requested to withdraw from the study; * Patients were unable to receive regular doses of third-generation EGFR inhibitors due to other underlying conditions, viral side effects, economic factors, etc. (e.g., continuous discontinuation for more than 1 week, cumulative discontinuation for more than 2 weeks). * Patients did not follow the protocol for follow-up visits as required by this study.
