Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

In previous studies, Proton Beam Radiation Therapy (PBRT) has been found to show better results in treating patients with cancer, both because there is better control of where in the body the radiation is directed and because it is associated with less severe long term side effects. However, there is limited published data demonstrating these results. The goal of the Proton and Photon Consortium Registry (PPCR) is to enroll children treated with radiation in order to describe the population that currently receives radiation and better compare the short-term and long-term benefits of different types of radiotherapy. The data collected from this study will help facilitate research on radiation therapy and allow for collaborative research. The PPCR will collect demographic and clinical data that many centers that deliver radiation therapy already collect in routine operations.
