Summary: The purpose of this study is to examine the use of tozuleristide and the Canvas imaging system during surgical resection of primary central nervous system tumors, to identify which tumor types demonstrate detectable fluorescence following administration of 24 mg tozuleristide and imaged with the Canvas imaging system during surgical resection, and, among tumors that demonstrate fluorescence, to es...
Summary: Hypothalamic obesity (HO) is defined as obesity secondary to functional or anatomical alterations of the hypothalamus, the central organ of energy homeostasis. The causes of HO are related either to hypothalamic lesions (eg craniopharyngioma) either to genetic diseases (syndromic obesity such as Prader-Willi syndrome or monogenic non syndromic obesity such as variants on leptin/melanocortin pathwa...
Summary: KRANIOPHARYNGEOM Registry 2019 will prospectively collect and descriptively analyse data on diagnostics, treatment, and follow-up of patients with craniopharyngioma. In continuation of preceding studies also patients with xanthogranuloma, meningioma, pituitary adenoma, prolactinoma and cystic intracranial malformations will be registered.
Summary: This is a prospective longitudinal study to access postoperative 2-year quality of life in patients who undergo endonasal endoscopic approach surgeries of the skull base.
Summary: This study will be conducted in two phases. The first phase (phase 0) will be looking at patients with new or recurrent/ progressed craniopharyngioma tumors. These patients will be given one dose of tocilizumab before they have SOC surgery of their tumor. The objective of this phase is to see if drug reaches the tumor. If phase 0 is favorable and shows that drug is penetrating the tumor, the secon...
Summary: The first proton therapy treatments in the Netherlands have taken place in 2018. Due to the physical properties of protons, proton therapy has tremendous potential to reduce the radiation dose to the healthy, tumour-surrounding tissues. In turn, this leads to less radiation-induced complications, and a decrease in the formation of secondary tumours. The Netherlands has spearheaded the development ...
Summary: Paraoptic tumors - including mostly sellar meningiomas, pituitary gland adenomas and craniopharyngiomas - classically affect the visual function. Some preoperative factors, determined on retrospective studies, are known to constitute bad prognostic factors, such as duration of symptoms and retinal nerve fiber layer thinning on OCT. We propose to perform a single center prospective study in which d...
Summary: Children with brain tumors who have had radiation therapy are at risk for problems with attention, memory, and problem solving. Such problems may cause difficulty in school and daily life. Memantine, the drug being used for this study, is not yet approved for use in children by the U.S. Food and Drug Administration. However, studies have shown some improvements in memory for patients with dementia...
Summary: This phase II trial studies how well vemurafenib and cobimetinib work in treating patients with BRAF V600E mutation positive craniopharyngioma. Vemurafenib and cobimetinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
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 ...
Summary: There is no consensus in the literature on the best way to treat cystic lesions of the pituitary area. Patients who are symptomatic from these tumours are rare. The cystic form of tumours present special challenges since traditional treatment modalities (surgery and/or external radiation) are often not able to completely remove or treat the cyst wall without major morbidity or even mortality.~Ther...
