Long-Term Longitudinal QoL in Patients Undergoing EEA
Pituitary TumorMeningioma6 moreThis 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.
Longitudinal Prospective Study of Neurocognition & Neuroimaging in Primary BT Patients
Primary Brain TumorGlioma2 moreIn this proposal, the investigators introduce a novel, translational study to prospectively examine primary brain tumor patients undergoing fractionated radiation therapy to the brain. Quantitative neuroimaging, radiation dose information, and directed neurocognitive testing will be acquired through this study to improve understanding of cognitive changes associated with radiation dosage to non-targeted tissue, and will provide the basis for evidence-based cognitive- sparing brain radiotherapy.
Cognitive Status After Removal of Skull Base Meningioma
MeningiomaSkull Base Meningioma5 moreThe purpose of this prospectively enrolling trial is to assess long-term cognitive outcomes of patients undergoing surgery for resection of a meningioma associated with the frontal and temporal lobes.
Petro-trigeminal Line and Petrous Apex Cephaloceles
Petrous Apex Meningiomacephaloceles are rare lesions of the petrous apex, inconsistently listed as meningoceles or arachnoid cysts. They're consistent with a herniation posterolateral of the Meckel cavum within the petrous apex. These lesions may be the cause of a symptomatology varied, or be discovered by chance in subjects who have not been asymptomatic. Currently, there is no evidence in the literature a simple, fast and reproducible radiological marker that allows for the diagnosis of cephaloceles of the petrous apex, in particular the small ones. The purpose of this study is to validate a radiological benchmark simple and reproducible, the trigeminal petrol line, in order to improve the diagnosis of petrous apex cephaloceles
Frequency and Clinical Phenotype of BAP1 Hereditary Predisposition Syndrome
Uveal MelanomaCutaneous Melanoma6 moreThis research will have a significant impact on the overall management of those cancer patients and their family members who are at risk for hereditary cancer due to germline inactivation of BAP1. Our study will ultimately facilitate the development of novel screening, prevention and treatment strategies for these individuals with the syndrome. Because the vast majority of UM develop in pre-existing nevi, characterization of individuals at high risk for development of UM will allow closer screening and earlier intervention which would improve the treatment outcome not only for retaining vision but also for overall survival. Similarly in patients with germline BAP1 mutation CM develops in premalignant atypical melanocytic lesions and careful follow up of these patients will improve the outcome of their disease. In addition this study could have impact on the management of patients with personal and/or family history of several other cancers reported in patients with germline BAP1 mutation such as mesothelioma, renal cell carcinoma, cholangiocarcinoma, hepatocellular carcinoma, meningioma and basal cell carcinoma.
Identification by Transcriptomic Approach of New Prognostic and Predictive Markers in a Cohort of...
Meningioma AtypicalDetermine by a transcriptomic approach new prognostic and predictive markers in atypical meningiomas (WHO grade II). Retrospective observational study, on a cohort of 85 atypical meningiomas. Transcriptomic study first, on cryopreserved tumor samples. Then identify, thanks to the transcriptomic study, prognostic and predictive factors (study of the link between the quantity of certain RNA transcripts and progression-free survival). Finally, set up immunohistochemical applications, which can be used routinely by the pathologist.
Proton Therapy Research Infrastructure- ProTRAIT- Neuro-oncology
AstrocytomaEpendymoma10 moreThe 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 of the model-based approach (MBA) for the selection of patients for proton therapy when applied to prevent radiation-induced complications. In MBA, a pre-treatment in-silico planning study is done, comparing proton and photon treatment plans in each individual patient, to determine (1) whether there is a significant difference in dose in the relevant organs at risk (ΔDose), and (2) whether this dose difference translates into an expected clinical benefit in terms of NormalTissue Complication Probabilities (ΔNTCP). To translate ΔDose into ΔNTCP, NTCP-models are used, which are prediction models describing the relation between dose parameters and the likelihood of radiation-induced complications. The Dutch Society for Radiotherapy and Oncology (NVRO) setup the selection criteria for proton therapy in 2015, taking into account toxicity and NTCP. However, NTCP-models can be affected by changes in the irradiation technique. Therefore, it is paramount to continuously update and validate these NTCP-models in subsequent patient cohorts treated with new techniques. In ProTRAIT, a Findable, Accessible, Interoperable and Reusable (FAIR)data infrastructure for both clinical and 3D image and 3D dose information has been developed and deployed for proton therapy in the Netherlands. It allows for a prospective, standardized, multi-centric data from all Dutch proton and a representative group of photon therapy patients.
Phase II Study of SOM230 in Patients With Recurrent or Progressive Meningioma
CancerThis is a single-arm, phase II trial of SOM230 in patients with documented recurrent or progressive intracranial meningioma who have failed conventional therapy and are not candidates for complete surgical resection of their tumors and/or radiation at the time of study entry. At the time of the final analysis, all patients who are receiving treatment with SOM230 will complete the core phase of the study and will continue on the extension phase. During this time, additional data on response duration, PFS, and safety will be collected.
Antineoplaston Therapy in Treating Patients With Meningioma
MeningiomaRATIONALE: Current therapies for adults with meningioma provide limited benefit to the patient. The anti-cancer properties of Antineoplaston therapy suggest that it may prove beneficial in the treatment of adults with meningioma. PURPOSE: This study is being performed to determine the effects (good and bad) that Antineoplaston therapy has on adults with meningioma.
Gamma-Secretase Inhibitor RO4929097 in Treating Young Patients With Relapsed or Refractory Solid...
Childhood Atypical Teratoid/Rhabdoid TumorChildhood Central Nervous System Choriocarcinoma45 moreThis phase I/II clinical trial is studying the side effects and best dose of gamma-secretase inhibitor RO4929097 and to see how well it works in treating young patients with relapsed or refractory solid tumors, CNS tumors, lymphoma, or T-cell leukemia. Gamma-secretase inhibitor RO4929097 may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.
