Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

The Johns Hopkins Proton Therapy center is establishing a registry to capture the full 3D radiation dosimetry delivered to the patient, baseline clinical data, and disease, toxicity and quality of life outcomes. The goal is to have all patients treated at the proton center to be included in the registry to enable future comparisons of treatment outcomes to assist in understanding which patients can benefit from the use of protons.
