Investigational Imaging Technique During Brain Surgery

AstrocytomaGlioblastoma1 more

This early phase I trial tests the safety and reliability of an investigational imaging technique called quantitative oblique back illumination microscopy (qOBM) during brain surgery for detecting brain tumors and brain tumor margins in patients with glioblastoma, astrocytoma, or oligodendroglioma. Surgical margins refer to the edge or border of the tissue removed in cancer surgery. qOBM may be able to assess and reveal brain tumor surgical margins in a more safe and reliable manner.

Repeated Super-selective Intraarterial Cerebral Infusion Of Bevacizumab Plus Carboplatin For Treatment...

Glioblastoma MultiformeAnaplastic Astrocytoma

The high-grade malignant brain tumors, glioblastoma multiforme (GBM) and anaplastic astrocytoma (AA), comprise the majority of all primary brain tumors in adults. This group of tumors also exhibits the most aggressive behavior, resulting in median overall survival durations of only 9-12 months for GBM, and 3-4 years for AA. Initial therapy consists of either surgical resection, external beam radiation or both. All patients experience a recurrence after first-line therapy, so improvements in both first-line and salvage therapy are critical to enhancing quality-of-life and prolonging survival. It is unknown if currently used intravenous (IV) therapies even cross the blood brain barrier (BBB). The investigators have shown in a previous phase I trial that a single Superselective Intraarterial Cerebral Infusion (SIACI) of Bevacizumab (up to 15mg/kg) is safe and effective in the treatment of recurrent GBM. Therefore, this phase I/II clinical research trial is an extension of that trial in that the investigators seek to test the hypothesis that repeated dosing of intra-arterial Bevacizumab is safe and effective in the treatment of recurrent malignant glioma. Additionally the investigators will analyze if a combination with IA Carboplatin will further improve the treatment response. By achieving the aims of this study the investigators will also determine if IV therapy with Bevacizumab with IV Carboplatin should be combined with repeated selected intra-arterial Bevacizumab plus Carboplatin to improve progression free and overall survival. The investigators expect that this project will provide important information regarding the utility of repeated SIACI Bevacizumab therapy for malignant glioma, and may alter the way these drugs are delivered to the investigators patients in the near future.

Loupe-Based Intraoperative Fluorescence Imaging

Glioblastoma MultiformeAnaplastic Astrocytoma

Glioblastoma multiforme (GBM) and anaplastic astrocytoma (AA) are the most common primary malignant brain tumors. Survival of patients with these brain tumors is directly related to the extent of resection. Consequently, a great deal of effort has been directed at developing techniques and technologies that allow more extensive, safe resections. This study will test a loupe-based wearable device in the clinical setting and compare its accuracy with a large operative microscope to identify tumor tissues. Postoperative histopathological analysis on tumor tissues will be used as gold standards for comparison. The outcome from this study will be a low-cost, miniaturized, easy-to-operate, loupe-based fluorescence imaging device for intraoperative guidance of brain tumor resection with the same level of accuracy as the large microscope.

Proton Therapy Research Infrastructure- ProTRAIT- Neuro-oncology

AstrocytomaEpendymoma10 more

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 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.

FORWARD Optune and Adjuvant TMZ in Grade II/III Astrocytoma

AstrocytomaGrade II2 more

This is a phase 2, multi-institutional, historically-controlled, study of 100 patients with newly diagnosed Grade II and III astrocytoma comparing the combination of TTFields with adjuvant temozolomide versus temozolomide alone in historical controls after the completion of definitive chemoradiotherapy. Study treatment may continue past first tumor recurrence. The primary endpoint will be overall survival.

Stem Cell Radiotherapy and Temozolomide for Newly Diagnosed High-grade Glioma

GlioblastomaMalignant Glioma2 more

There are preliminary studies that suggest that radiation therapy to areas of the brain containing cancer stem cells (in addition to the area where the tumor was surgically treated) may help patients with high-grade brain tumors live longer. The purpose of this study is to determine whether the addition of stem-cell radiation therapy to the standard chemoradiation will further improve the outcome. The investigators will collect information about the patient's clinical status, disease control, neurocognitive effects, and quality of life during follow-up in our department. The purpose of the study is to improve the overall survival patients with newly diagnosed malignant brain tumors treated with stem cell radiation therapy and chemotherapy. The investigators will also measure how patients treated with this novel method of radiation therapy do over time in terms of disease control, potential neurocognitive side effects, overall function, and quality of life.
