Precision proton beam aims to zap liver tumors with fewer side effects

NCT ID NCT00976898

First seen Jun 26, 2026 · Last updated Jun 26, 2026

Summary

This study tested proton beam radiation, a highly targeted form of radiotherapy, in 83 people with liver cancer that could not be surgically removed. The goal was to see if this precise approach could control tumors while reducing damage to healthy tissue. Participants received daily treatments for three weeks, and researchers tracked tumor control and survival over two years.

Active substance

Proton beam radiation

What this could lead to

If successful, this could offer a more precise and safer radiation option for people with liver cancer that cannot be removed by surgery.
