Is it acceptable to treat patients with limited, asymptomatic brain metastases and EGFR-mutant NSCLC with upfront TKI?

Can SRS or whole brain radiotherapy be reserved for progression in these young, healthy patients?

Though some clinicians have been exploring the idea of targeted therapy for EGFR mutant brain metastases, this has been done in the absence of strong evidence. Reasons for pushing this idea are that sometimes the lesions seem to respond, and this has been seen in some single arm studies and anecdota...

I would treat patients with limited, asymptomatic brain metastases with SRS followed by EGFR-TKI based upon the studies (particularly the recently published Journal of Clinical Oncology study) cited by @Dr. First Last above.

In full disclosure, I am obviously the first author on both of the manuscrip...

In the era of newer generation TKIs with increased CNS activity (e.g., osimertinib for EGFR+; alectinib, lortlatinib, brigatinib for ALK+ NSCLC), the short answer is “yes”, it is acceptable to treat carefully selected patients with limited brain metastases with upfront CNS-active TKIs and close MRI ...

I think the answers to this question above make some great points. However, old data on this topic are now a bit outdated with the recent results of the FLAURA trial which moved the third-generation TKI osimertinib to first-line therapy for EGFR-mutants.

Most of the first and second-line EGFR agents ...

I often hold off on RT if lesions small and asymptomatic. But I never stop close surveillance.

I would likely proceed with SRS upfront for limited small metastasis and asymptomatic and consider holding off if patient is comfortable with close surveillance.

New data from a randomized study in EGFR & ALK mutated NSCLC patients with asymptomatic brain mets demonstrate that upfront CNS treatment with either SRS or WB-XRT +/- boost delayed intracranial progression compared to delayed treatment. There was no difference in overall progression or overall surv...

In my opinion, patients with asymptomatic brain mets from EGFR-mutated NSCLC can initially be treated with erlotinib. I have had a few such cases, and initially the brain mets respond to erlotinib. However, they appear to universally progress in the brain necessitating radiotherapy or SRS. Studies i...

I would treat if the patient wishes to be on close surveillance with repeat MRI. Most of my patients prefer treatment than getting frequent MRI studies.

I would treat with SRS now to prevent problems in future. Besides, I think patients with known brain mets will really worry if not treated.
