Multicentre Validation of How Vascular Biomarkers From Tumor Can Predict the Survival of the Patient...

Glioblastoma

Despite an aggressive therapeutic approach, the prognosis for most patients with glioblastoma (GBM) remains poor. The relationship between non-invasive Magnetic Resonance Imaging (MRI) biomarkers at preoperative, postradiotherapy and follow-up stages, and the survival time in GBM patients will be useful to plan an optimal strategy for the management of the disease. The Hemodynamic Multiparametric Tissue Signature (HTS) biomarker provides an automated unsupervised method to describe the heterogeneity of the enhancing tumor and edema areas in terms of the angiogenic process located at these regions. This allows to automatically draw 4 reproducible habitats that describe the tumor vascular heterogeneity: The High Angiogenic enhancing Tumor (HAT) The Less Angiogenic enhancing Tumor (LAT) The potentially tumor Infiltrated Peripheral Edema (IPE) The Vasogenic Peripheral Edema (VPE) The conceptual hypothesis is that there is a significant correlation between the perfusion biomarkers located at several HTS habitats and the patient's overall survival. The primary purpose of this clinical study is to determine if preoperative vascular heterogeneity of glioblastoma is predictive of overall survival of patients undergoing standard-of-care treatment by using the HTS biomarker.

Metabolic Tumor Volumes in Radiation Treatment of Primary Brain Tumors

Brain TumorGlioblastoma Multiforme

Metabolic Tumor Volume (MTV), identified by Magnetic Resonance Spectroscopic Imaging (MRSI) is different from the Clinical Target Volume (CTV) used for radiation dose delivery in the treatment of brain tumors. If MTV > CTV, the investigators hypothesize that the difference in volumes (cc) is related to worse clinical outcome. Furthermore, in case of local recurrence, the lesion is located in the MTV area that is outside of the CTV. Alternatively, if CTV > MTV, then the difference in volumes is related to higher treatment toxicity.

Evaluation of FLT PET and MRI as Imaging Biomarkers of Early Treatment Response in Patients With...

Glioblastoma

Glioblastoma is the most common primary malignant neoplasm of the adult brain. Even after multimodal therapy, outcomes remain poor, with a median survival of one year. Although advanced imaging methods have been suggested as molecular markers of prognosis and therapeutic response, these methods have not been validated for clinical use. In this exploratory, imaging-based, trial, thirty patients with a pathological diagnosis of glioblastoma will be followed prospectively for two years. The study examines how PET and MR imaging signals change following administration of a standard radio-chemotherapy treatment regimen to determine whether these imaging modalities can provide early indicators of response to therapeutic intervention. The investigators hypothesize that decreases in uptake of an investigational 18F-FLT PET tracer following treatment with radiation and chemotherapy will be a reliable predictor of glioblastoma response. In a more exploratory fashion, the investigators also will identify changes in diffusion and hypoxia MR imaging that may also correlate well with treatment response.

PET/CT Imaging of Malignant Brain Tumors With 124I-NM404

GlioblastomaBrain Metastases

The purpose of this study is to evaluate diagnostic imaging techniques using 124I-NM404 PET/CT in humans with brain metastases and GBMs. This goal will be accomplished by determining the optimal PET/CT protocol and comparing PET tumor uptake to MRI and calculating tumor dosimetry. A future aim of this study will be to compare non-invasive PET/CT and MRI findings with pathological specimens, which is the gold standard but is invasive and impractical in many cases, to determine the sensitivity and specificity of both techniques for accurately detecting tumor infiltration. The data obtained from this study will be used to develop larger diagnostic and therapeutic trials in brain tumors. The long-term goals of this research are to improve the diagnosis and treatment of malignant brain tumors by using radioiodinated NM404.

TVI-Brain-1 in Expanded Access Patient

Recurrent Glioblastoma

TVI-Brain-1 is being offered as a potential treatment option to a Named Patient (Emergency Use Authorization IND) for recurrent glioblastoma as there is no effective systemic treatment available for this disease or patient. TVI-Brain-1 is an experimental treatment that takes advantage of the fact that your body can produce immune cells, called 'killer' white blood cells that have the ability to kill large numbers of the cancer cells that are present in your body. TVI-Brain-1 is designed to generate large numbers of those 'killer' white blood cells and to deliver those cells into your body so that they can kill your cancer cells.

Impact of [11C]-Methionine PET/MRI for Individual Tailoring Postoperative Radiochemotherapy for...

Glioblastoma Multiforme

Local recurrence is a major problem of clinical treatment of glioblastoma multiforme (GBM). Today a very sensitive imaging method to detect glioblastoma is [11C]MET Positron emission tomography (PET), where in some patients also tumour manifestations can be detected that are not visible in MRI investigations. The aim of the study is to investigate the association of high [11C]MET tracer uptake before postoperative radiochemotherapy and concurrent temozolomide (TMZ) with time to recurrence in patients with glioblastoma multiforme. Also site of recurrence will be correlated with the [11C]MET imaging before and early during radiochemotherapy. All imaging information will be included in treatment planning or treatment decisions. The study provides a basis for later radiation dose escalation trials on the base of [11C]MET imaging.
