Two-Part Study to Evaluate the Safety and Efficacy of Image Guided Surgery Using Indocyanine Green for Intramolecular Imaging of Nervous System Tumors Compared to Standard of Care, (TumorGlow)
Primary malignant and non-malignant brain tumors account for an estimated 21.42 cases per 100,000 for a total count of 343,175 incident tumors based on worldwide population estimates [1]. These entities result in variable but disappointing rates of survival, particularly for primary brain tumors (5-year survival rates: anaplastic astrocytoma 27%; glioblastoma multiforme 5%) [2, 3]. Metastatic brain tumors outnumber primary brain tumors (estimates as high as 10:1) as they affect approximately 25% of patients diagnosed with cancer [4-6]. In terms of brain tumor surgery, the extent of surgical resection-a factor that is greatly impacted by a Neurosurgeon's ability to visualize these...

UNIty-Based MR-Linac Guided AdapTive RadiothErapy for High GraDe Glioma: a Phase 2 Trial
Glioblastoma (GBM) is a high grade glioma (brain tumor) that is treated with surgery or biopsy followed by radiotherapy (RT) given daily over 3 or 6 weeks with or without an oral chemotherapy. Radiation is targeted to the visible residual tumor on magnetic resonance imaging (MRI) images plus a large margin of 15 to 30 mm to account for possible cancer cells outside the visible tumor and for potential growth or shifts in tumor position throughout the prolonged RT course. Standard RT uses MRI to create a reference plan (with large margins) and treats that same volume every day. This exposes a large amount of healthy brain tissue to radiation leading to toxicity and reduced quality...

Upfront Bevacizumab/témozolomide for Gliomastomas With Neurological Impairment
New approaches are needed for patients newly diagnosed with bulky glioblastoma (GB) and/or with severe neurological impairment that cannot benefit from first line temozolomide (TMZ)-basedn chemoradiotherapy. Bevacizumab (BEV), an antiangiogenic anti-VEGF-R monoclonal antibody, has a rapid impact on tumor-related brain edema in recurrent GB. The present study reports the feasibility and efficacy of an induction treatment with TMZ and BEV to alleviate the initial neurological impairment and/or to reduce the tumor volume before a delayed chemoradiotherapy.

Usefulness of Gadovist-enhanced FLAIR Imaging
Polyplastic glioblastoma and metastatic brain cancer are the most common malignant brain tumors in adults. The primary diagnostic test for tumors in the brain shows magnetic resonance imaging or similar imaging findings (especially single metastatic brain cancer) that make it difficult to distinguish between these two diseases. In addition, due to the specificity of the tissue called the brain, biopsy is not easy and sometimes biopsy is difficult, so non-invasive discrimination is often important, and it is important how much prediction is made before the biopsy. To solve this problem, various advanced magnetic resonance imaging techniques have been studied, but they are all tests...

Usefulness of Therapy Monitoring by Means of [(18)F]Fluoroethyltyrosine-Positron Emission Tomography (FET-PET) in Glioblastoma Multiforme Patients
The aim of this study is to establish FET-PET as an additional therapy assessment parameter in patients diagnosed with a glioblastoma multiforme receiving radiochemotherapy and adjuvant chemotherapy after previous resection or biopsy.

Using Genomic Analysis to Guide Individual Treatment in Glioblastoma
The purpose of this study is to assess whether the use of genomics can help identify patient specific treatment choices in cancer. In order to test this, the investigators plan to use genomic sequencing technology to identify patient specific mutations in glioblastoma multiforme (GBM) as compared to normal cells to identify mutations. Further analysis will identify potential treatment targets and whether there are any drugs that could be used for these particular mutations. Follow up clinical data will be assessed to see if this individualized method of choosing treatment options can improve clinical outcomes in patients with GBM.

Vaccination With Dendritic Cells Loaded With Brain Tumor Stem Cells for Progressive Malignant Brain Tumor
This is a single center Phase I study to determine the safety and maximum tolerated dose (MTD) of autologous dendritic cells (DCs) loaded with allogeneic brain tumor stem cells administered as a vaccination in children and adults with recurrent brain tumors. Once the MTD has been determined, we will conduct a phase II study to determine efficacy. Clinical trials that utilize DCs for immunotherapy have demonstrated significant survival benefit for patients who exhibit robust immune responses against tumor cells. Unfortunately, at the present time the majority of tumor patients are unable to mount an adequate immune response and thus succumb to their tumors. We postulate that...

Vaccine Therapy and Sargramostim in Treating Patients With Malignant Glioma
This phase I trial studies the side effects of vaccine therapy when given together with sargramostim in treating patients with malignant glioma. Vaccines made from survivin peptide may help the body build an effective immune response to kill tumor cells. Colony-stimulating factors, such as sargramostim, may increase the number of white blood cells and platelets found in bone marrow or peripheral blood. Giving vaccine therapy and sargramostim may be a better treatment for malignant glioma.

Vaccine Therapy and Sargramostim in Treating Patients With Sarcoma or Brain Tumor
RATIONALE: Vaccines may make the body build an immune response to kill tumor cells. Colony-stimulating factors such as sargramostim increase the number of immune cells found in bone marrow or peripheral blood. Combining vaccine therapy with sargramostim may cause a stronger immune response and kill more tumor cells. PURPOSE: This phase I trial is studying the side effects of vaccine therapy when given together with sargramostim in treating patients with advanced sarcoma or brain tumor.

Vaccine Therapy and Temozolomide in Treating Patients With Newly Diagnosed Glioblastoma
This pilot clinical trial studies vaccine therapy and temozolomide in treating patients with newly diagnosed glioblastoma. Vaccines made from a person's white blood cells mixed with tumor proteins may help the body build an effective immune response to kill tumor cells. Drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving vaccine therapy and temozolomide may be an effective treatment for glioblastoma.
