Zapping just a few spots: new hope for patients with worsening metastatic cancer?
NCT ID NCT04122469
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether using highly focused radiation (SBRT) on a limited number of growing cancer spots can help control the disease in patients with metastatic breast or genito-urinary cancers. Instead of switching to a new drug when some tumors start growing, doctors will target only those spots with radiation. The goal is to safely delay further progression and improve quality of life. About 130 adults will be followed for up to 2 years.
