FLASH therapy: a flash of hope for head and neck cancer retreatment?
NCT ID NCT07644585
First seen Jun 27, 2026 · Last updated Sep 18, 2026 · Updated 3 times
Summary
This early study tests a new type of radiation therapy called ConformalFLASH, which delivers radiation at an ultra-high speed. It is for 10 adults with head and neck cancer who need a second round of radiation but cannot have surgery. The goal is to see if this fast treatment is possible and safe, with the hope of reducing side effects compared to standard radiation.
