Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Despite the impressive response rate to third-generation EGFR-TKIs, resistance inevitably develops in most patients. Stereotactic radiotherapy plays a growing role in the management of patients with brain metastasis. This study aims to evaluate the efficacy and safety of stereotactic radiotherapy for oligo-residual intracranial disease after first-line third-generation EGFR Inhibitors.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

3rd generation EGFR-TKI+SRS

The experimental arm will undergo stereotactic radiotherapy targeting all residual lesions in the brain (completed in a single or multiple treatment courses within one month), while continuing EGFR-TKI therapy until disease progression or intolerable toxicity occurs.

Group Type EXPERIMENTAL

EGFR-TK Inhibitor

Intervention Type DRUG

Patients will receive EGFR-TKI until confirmed progression or unacceptable toxicity.

Stereotactic radiotherapy

Intervention Type RADIATION

Patients with oligo-residual intracranial disease after treatment with EGFR-TKI will be treated with SRS of all intracranial lesions. The choice of dose-fractionation regimen is at the discretion of the treating radiation oncologist.

3rd generation EGFR-TKI

The control group will receive 3rd generation EGFR-TKI until disease progression or intolerable toxicity occurs.

Group Type ACTIVE_COMPARATOR

EGFR-TK Inhibitor

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

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.
