Proton GRID radiation: a new hope for painful, bulky tumors?
NCT ID NCT05831579
First seen Feb 02, 2026 · Last updated May 23, 2026 · Updated 15 times
Summary
This study tests a special type of proton radiation called GRID to relieve symptoms from large tumors (at least 4.5 cm) that cannot be surgically removed or have spread. The treatment delivers high-dose radiation in a pattern of peaks and valleys, aiming to be effective while reducing side effects. About 24 adults with cancer who need palliative radiation will participate, including some whose tumors have been previously treated with radiation. The main goal is to check safety and side effects.
