About this study

The purpose of the Pediatric Proton Consortium Registry (PPCR) is to enroll children who have been treated with proton radiation in the United States in order to describe the population that currently receives protons and better evaluate its benefits over other therapies. The data collected from this study will help facilitate research on proton beam radiation therapy and allow for collaborative research. The PPCR will collect demographic and clinical data which many centers that deliver proton radiation therapy already collect in routine operations.
