CRANIOPHARYNGIOMA

This study tests whether using limited surgery followed by proton therapy can control craniopharyngioma, a rare brain tumor, in children and young adults. The goal is to reduce radiation side effects by using a tighter radiation margin. Some patients who have complete tumor remov…

This study tests a newer form of radiation called intensity-modulated proton therapy in children and young adults with craniopharyngioma, a rare brain tumor. The goal is to see if this precise radiation can better control the tumor while causing fewer side effects than older radi…

This study tests whether a special PET scan using a radioactive form of methionine (a natural amino acid) can help doctors see tumors in children and young adults with various cancers, including brain tumors and sarcomas. About 503 participants will be scanned to see if the metho…

This study follows 400 patients for two years after they have endoscopic endonasal skull base surgery (surgery through the nose to reach the base of the skull). The goal is to measure their quality of life and nose function using standard questionnaires. It does not test a new tr…

This study follows 75 adults with benign or slow-growing brain tumors who are receiving partial brain radiation. Researchers will use memory tests and MRI scans before treatment and at 6 and 12 months after to see how radiation affects thinking and memory. The goal is to identify…
