SRS Use in Lung Cancer Brain Metastases: Who Gets Treated?

Patients with brain spread from lung cancer often need radiation. A precise form called stereotactic radiosurgery can treat a few spots instead of the whole brain, but not everyone receives it. Studies show that who gets this treatment depends on age, income, and insurance type. Older patients and those with lower incomes are less likely to be offered the targeted therapy. The data come from national records covering adults across the United States who were diagnosed with brain lesions from lung cancer. Researchers compared the numbers of people receiving stereotactic radiosurgery to those who received traditional whole‑brain radiation. Findings reveal a clear gap: people with better insurance coverage and higher household earnings receive the newer, less invasive option more often. Even after adjusting for tumor size and overall health, these disparities remain.Why does this matter? Stereotactic radiosurgery can spare patients from cognitive side effects that whole‑brain radiation often causes. If certain groups are missing out, they may face worse quality of life and higher treatment costs later on. Addressing the issue requires policy changes that make advanced treatments more accessible, regardless of socioeconomic status. It also calls for clinicians to examine their own referral patterns and ensure every eligible patient is informed about all available options. Future research should track outcomes over time to see if narrowing these gaps improves survival and patient satisfaction across all communities.
