Active clinical trials for "Astrocytoma"

Radiomics, the extraction of large amounts of quantitative image features to convert medical images into minable data, is an in-development field that intends to provide accurate risk stratification of oncologic patients. Published prognostic scores only take clinical variables into account. The investigators hypothesize that a combination of CT/MRI features, molecular biology and clinical data can provide an accurate prediction of medical outcome. The long term objective is to build a Decision Support System based on the predictive models established in this study.

The purpose of the study is to determine the clinical safety and operability of the innovative tissue imprint device ProTool.

This trial studies the natural history of brain function, quality of life, and seizure control in patients with brain tumor who have undergone surgery. Learning about brain function, quality of life, and seizure control in patients with brain tumor who have undergone surgery may help doctors learn more about the disease and find better methods of treatment and on-going care.

The purpose of this study is to confirm the safety and efficacy of temozolomide in patients with newly diagnosed malignant glioma (concomitant with radiotherapy and then as monotherapy) and relapsed malignant glioma (as monotherapy) when used in the daily medical practices. Post-marketing surveys are not considered applicable clinical trials and thus the results of this survey will not be posted at its conclusion. The results will be submitted to public health officials as required by applicable national and international laws.

According to the O.M.S. Classification, grade 2 glioma is a pre-cancerous lesion, slowly progressive, infiltrating the central nervous system, mainly affecting young adults. This surgery should nevertheless be conducted in awake condition to achieve two conflicting goals: get maximum brain tissue infiltrated by the tumor while preserving the integrity of functional structures. So awake after opening the skull, the patient undergoes a series of preoperative tests, administered by a speech therapist present in the operating room. This procedure allows the neurosurgeon to establish an individual functional brain mapping in real time, through the observation by the SLP of the patient's answers to direct electrical stimulation applied to the cortical and sub-cortical. This support is based on the extraordinary plasticity demonstrated by the brain in the presence of a slowly progressive lesion. To ensure the patient the highest achievable load should increase our understanding of brain function, including the neural bases of language, glioma grade 2 is predominantly localized functional area of language.

The Investigators will examine the disease specificity of 2-hydroxyglutarate in non-glioma brain lesions, and the clinical utility of 2-hydroxyglutarate, glycine and citrate in isocitrate dehydrogenase (IDH) mutated gliomas and IDH wild type gliomas.

RATIONALE: Gathering information over time from laboratory tests of patients with newly diagnosed malignant supratentorial astrocytoma may help doctors learn more about the effect of treatment on white blood cell count and the risk of infection. PURPOSE: This clinical trial is studying blood samples and risk of infection in patients with newly diagnosed malignant supratentorial astrocytoma.

In this explorative study immunological changes during tumor therapy will be analyzed in patients with malignant glioma. Immunophenotyping before and during therapy is used as analysis method. Thereby immune cells are quantitatively and qualitatively detected from patient's blood at continuous time points. Additionally relevant mediators like cytokines, danger signals and chemokines are analyzed by other methods. Obtained results may give information about the effects of therapy on immunological processes and immune cells and may help to find immunological based predictive or prognostic tumor markers and to define time points for including additional immune therapy in the future.

The purpose of this surveillance is to evaluate the postmarketing safety and efficacy of Temodal capsule (temozolomide) under actual conditions of use, and to understand some of the following points that are in question and doubt: Incidence of adverse events under actual conditions of use (Serious and Nonserious Adverse Events); Adverse Drug Reactions not shown in the directions for use (will be stated as Unexpected Adverse Reaction); Adverse Event caused by misuse, abuse, or drug interactions; Other information concerned with safety or efficacy.

International, multicenter, observational, longitudinal study to identify biomarker/s for Tuberous Sclerosis Complex and to explore the clinical robustness, specificity, and long´-term variability of these biomarker/s
