Radiation after targeted therapy may keep skin cancer away
NCT ID NCT05561634
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is for people with advanced basal cell skin cancer that has completely disappeared after taking targeted pills (vismodegib or sonidegib). The problem is that the cancer often returns when the pills are stopped. Researchers want to see if giving a short course of radiation therapy to the original tumor area can prevent the cancer from coming back. About 82 adults will take part, and half will get radiation plus standard monitoring, while the other half will only be monitored.
