New study tests skipping brain radiation when drugs work

NCT ID NCT06974370

First seen Jun 24, 2026 · Last updated Jun 24, 2026

Summary

This study is testing whether people with brain metastases from lung cancer or other solid tumors can safely avoid radiation therapy if their brain tumors shrink or stay stable with systemic treatments like immunotherapy, targeted therapy, or chemotherapy. Forty-five participants will be monitored with MRI scans every three months, and radiation will only be used if the tumors grow. The goal is to see if this approach is feasible and which patients might benefit most.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

systemic therapy (immunotherapy, targeted therapy, or chemotherapy)

What this could lead to

If successful, this could show that many patients with brain metastases can avoid radiation and its side effects by relying on systemic therapy and regular MRI scans.

What could go wrong

This is a small pilot study with only 45 participants, so results may not apply to everyone. Some patients may still need radiation if the cancer progresses.
