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.
