A Phase II Trial of Intensity-Modulated Proton Therapy for Incompletely Resected Craniopharyngioma and Observation for Craniopharyngioma After Radical Resection

Study Summary

Craniopharyngioma is a rare brain tumor that affects both children and adults. It arises in a region of the brain near the pituitary gland, visual pathways, and central blood vessels. Patients often present with headache, loss of vision or delayed growth. In some instances they may present with imbalance of water and salts in the body. The treatment for craniopharyngioma may be radical surgery or a combination of surgery and radiation therapy. In some instances surgery is not required. If the tumor cannot be completely removed, radiation therapy may be required. In this study we will use the most advanced form of proton therapy which is called intensity-modulated proton therapy. This is a newer form of radiation therapy which has a number of advantages over older forms of proton therapy and conventional radiation therapy using x-rays. The main goal of this study is to learn if proton therapy will effectively treat patients with craniopharyngioma brain tumors and reduce side effects compared to more traditional forms of radiation therapy.

Primary Outcome

PFS is defined as the interval of time from the initiation of radiation therapy (RT) until the earliest of the events: death from any cause; and disease progression.
