First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This registry follows up to 75,000 cancer patients treated with proton or standard X-ray radiation at Loma Linda University Medical Center, some since 1990. The goal is to track long-term outcomes like disease-free survival and local recurrence to learn which radiation approaches work best for different cancers. Participants must have a diagnosis treatable by radiation and provide consent.

Active substance
Proton or photon radiation therapy
What this could lead to
If successful, this registry could help doctors understand which types of radiation work best for different cancers, improving future treatment decisions.
