The general objective of this project is to evaluate the value of cell-free DNA circulating in plasma as a marker of tumor evolution in patients with high-grade gliomas and meningiomas. To this end, we propose to longitudinally collect four samples of plasma at the following time points: - T0: before surgery; - T1: one month after surgery; - T2: one month after the end of radiotherapy; - T3 at the time of radiological progression. The goal is to evaluate whether changes in plasma concentration of circulating cell-free DNA can help predict progression-free survival, overall survival, and response...
Randomized, placebo-controlled, double-blinded, parallel group clinical trial to investigate if 6 months of oral lithium tablets (S-lithium 0,5-1,0 mmol/l) will prevent cognitive decline after brain radiotherapy in pediatric brain tumor survivors. Primary outcome measure is Processing Speed Index (PSI) 2 years after start of study treatment.
The purpose of this study is to evaluate the treatment regimen of using Laser Interstitial Thermal Therapy (LITT) and Hypo-fractionated Radiation Therapy to treat patients with newly diagnosed gliomas.
The purpose of this study is to evaluate the treatment regimen of using Laser Interstitial Thermal Therapy (LITT) and Hypo-fractionated Radiation Therapy to treat patients with recurrent gliomas.
Loc3CAR is a Phase I clinical trial evaluating the use of autologous B7-H3-CAR T cells for participants ≤ 21 years old with primary CNS neoplasms. B7-H3-CAR T cells will be locoregionally administered via a CNS reservoir catheter. Study participants will be divided into two cohorts: cohort A with B7-H3-positive relapsed/refractory non-brainstem primary CNS tumors, and cohort B with brainstem high-grade neoplasms. Participants will receive six (6) B7-H3-CAR T cell infusions over an 8 week period. The purpose of this study is to find the maximum (highest) dose of B7-H3-CAR T cells that are safe to give patients with primary brain ...
To observe the quality of life (QOL) and to report on toxicity and outcome parameters after the (repeated) use of local ablative therapy (LAT) i.e. stereotactic radiotherapy (SRT) for patients with multiple (4-10) brain metastases
This research study is studying Proton Radiation as a possible treatment for brain tumor. The radiation involved in this study is: -Proton Radiation
This study is to improve the first-line induction chemotherapy, by combining either Ibrutinib, or Lenalidomide, to a conventional immuno- chemotherapy of R-MPV type (Rituximab-Methotrexate-Procarbazine-Vincristine). This is a randomized Phase II trial, preceded by a dose escalation phase Ib. The objective of the phase Ib is to rule out any limiting toxicity of the new treatment associations, and to determine the recommended dose of Lenalidomide and Ibrutinib to be used in the phase II. In the phase II study, patients will receive 4 cycles of R-MPV + Lenalidomide or 4 cycles of R-MPV + Ibrutinib. The therapeutic response will be...
Despite comprehensive multimodal treatment of newly diagnosed glioblastoma, almost all patients suffer from tumour relapse. Currently, no standard of care exists to treat these tumour relapses. Treatment options include repeated surgery (if feasible), systemic therapy (bevacizumab, lomustine, temozolomide re-challenge), reirradiation and best supportive care. Currently, the superiority of combined chemoradiation versus chemotherapy alone remains unproven. Given that lomustine is the standard chemotherapeutic agent for the treatment of recurrent glioblastoma in Europe and the unclear efficacy of reirradiation, we want to explore...
Gliomas are the most common primary intracranial tumors, representing at least 75% of all primary malignant brain tumors. Histopathologically, gliomas are classified into different subgroups including astrocytomas (60-70%), oligodendrogliomas (10-30%), ependymomas (<10%) and mixed gliomas (i.e. oligoastrocytomas) depending on the cell type from which they originate. The World Health Organization currently classifies gliomas based on histopathological analysis in which the presence (or absence) and the degree of specific histopathological features determines the grade of malignancy. Grade I (pilocytic astrocytoma) and grade II...
