Prospective Assessment of Quality of Life (QOL) in Pediatric Patients Treated With Radiation Therapy for Brain Tumors and Non-CNS Malignancies

In recent years, remarkable advances in medical oncology, surgery, and radiology have allowed for increasing cure rates for childhood malignancies. This success has led to an emerging understanding of the kinds of effects that treatments can have on the pediatric population and how such effects can influence pediatric cancer survivor's functioning and quality of life. It has become tremendously important to assess the long-term complications due to therapy in this growing sector of survivors and to tailor our treatments so as to minimize these late effects.

The Investigators at MGH are committed to improving the delivery of radiotherapy to our patients and improving the outcome for these patients. MGH has an on-site cyclotron for proton radiotherapy in order to provide the most advanced care for patients in need. Proton therapy possesses a clinical advantage over standard photon therapy in that its optimal dose distribution delivers the bulk of radiation to the tumor site. This method spares the greatest volume of normal tissue, resulting in decreased short-term and long-term morbidity.

Through open pediatric protocols for patients treated with proton radiotherapy, the investigators aim to define and report the acute and late effects associated with treatment.

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.

The aims of this study are: 1) to prospectively collect and report the QOL outcomes in patients treated with radiotherapy and 2) to correlate the QOL data with pertinent clinical information.
