The investigators also treat a number of patients off-protocol with both proton and photon radiotherapy, and are interested in reporting these patients' QOL outcomes in conjunction with other clinical data that may be pertinent to the site of tumor treatment. This research is significant in that it will allow us to delineate the positive and negative effects of radiation treatment on patients' QOL, highlighting points of success and exposing areas that are in need of improvement. Such knowledge will be used to improve the experience of pediatric cancer survivors in the future.
