Intraoperative Optical Imaging of Brain Function

Brain Tumor

The goal of this proposal is to test the performance of a novel optical imaging system for real-time quantitative imaging of brain function through multiple hemodynamic measures during neurosurgery. This pilot study encompasses two sub-aims: Evaluate the ability of laser speckle contrast imaging to image cerebral blood flow (CBF) intraoperatively. We will image the changes in CBF in response to somatosensory stimulation. (5 patients). Simultaneously image hemoglobin oxygenation, blood volume, blood flow, and cerebral metabolic rate of oxygen (CMRO2) changes during somatosensory stimulation using a combined laser speckle and multi-wavelength reflectance imaging system. (5 patients).

Monitoring Neural Tissues Properties by Modulated Imaging (MI)

Brain Tumor

We have developed a safe, non-contact, intra-operative guidance system to optimize tumor resection in neurosurgery. The Modulated Imaging is non-contact optical imaging technology developed at the Beckman Laser Institute, UCI. Compared to other imaging approaches, MI has the unique capability of performing both diffuse optical tomography and rapid, wide-field quantitative mapping of tissue optical properties within a single measurement platform. Preliminary in vivo studies have shown that brain tumors, infiltrating tumor margins and normal brain may have intrinsically different optical properties.

Evaluation of the Incidence of NTRK Gene Fusion in Adult Brain Tumours

Glioma

This is a retrospective, mono centric, exploratory study to assess the incidence of a genomic alteration: NTRK gene fusion, in adult gliomas and brain metastases.

Role of MR Spectroscopy in Brain Tumors

Brain Neoplasms

In order to come as close as possible to the correct diagnosis of CNS tumors, MRI is the long-standing accepted method of choice that can in some cases be supported by the use of CT to demonstrate calcification or bone destruction. In individual cases MRI spectroscopy can be helpful for the differentiation between neoplasms and inflammatory lesions or surveillance of tumor therapy, just as perfusion

Assistance in Neurosurgery (ExtempoRMN)

Primary Brain TumorGlioma

The main ambition of this project is to develop, and provide the medical community, an innovative method to analyze extemporaneously, during a neurosurgery operation, excised tissues. This method is based on the analysis of the metabolic profile of excised tissues by the technique of High-Resolution Magic-Angle Spinning (HR-MAS) Nuclear Magnetic Resonance (NMR) spectroscopy. Indeed HRMAS NMR method can provide in a sufficiently short time lapse (currently about 30 minutes but within our project a time lapse of 15 min or even less is ultimately intended), medical information that can complement those obtained by classic histological examination. Primary purpose: The main objective of this study is to determine the sensitivity of HRMAS NMR spectroscopy in detecting residual tumor infiltration at the brain resection cavity. The investigators aim to determine the relevance of the metabolic analysis compared to histological analysis during a neurosurgery operation. This involves analyzing excised tissue samples, obtained from the operating rooms of Strasbourg University Hospitals, and Colmar Hospital Center, with no return to neurosurgeon for surgery. Secondary purposes: The secondary objectives of the protocol are to investigate the metabolome of different types of brain tumors, in order to find prognostic and diagnostic markers. It consists in detecting metabolomic factors of bad prognosis, and potential marker of good prognosis such as the IDH mutation.

Retrospective Study of Ovarian Cancer Patients With Brain Metastasis

Ovarian CancerBrain Metastases

Ovarian cancer, especially epithelial ovarian carcinoma, has the highest mortality rate among the gynecologic malignancies. The majority of patients with epithelial ovarian carcinoma are diagnosed at advanced stage which has the overall survival rates of only 19-30%. As the advance in the managements which prolonged the overall survival, metastatic lesion in rare location such as brain was noted in few patients of ovarian cancer in recent years. In the retrospective study, the investigators will review the medical records of the ovarian cancer patients with brain metastasis in the investigators hospital to investigate the incidence, clinical courses, optimal managements and possible prognostic factors in the rare condition.

Linking Digital Smartphone Behaviour With Brain Function

Brain TumorHydrocephalus1 more

This study will thus examine daily behaviour based on smartphone use and link it to the neurological and neuropsychological status as well as to neuroradiological studies that are part of the clinical routine. The study will examine behaviour changes before and after surgery, and how this change in measured behaviour with the smartphone relates to today's "gold standard", namely professional neuropsychological examination and quantification of brain damage on imaging studies (MRI). This study is a proof-of-principle study that intends to build the basis for larger future observational studies on patients with focal or diffuse brain pathologies.

Spinal Motor Evoked Potentials in Brain Surgery

Brain TumorGlioma

During neurosurgical resection of brain tumors within brain areas for motor control, it is important to monitor motor function. For this muscle motor evoked potentials are used. Those are elicited by transcranial and direct cortical stimulation. Motor responses are recorded from muscles. In neurosurgical procedures for spinal cord tumors, the same methods are used, but additionally motor activity is recorded from the spinal cord. This is called spinal motor evoked potentials. It is known that the relation between spinal and muscle motor evoked potentials helps to extent the resection of spinal cord tumors. This study implements the spinal motor evoked potential into brain tumor surgery and analyses the relationship between spinal and muscle motor evoked potentials. With this, detection of injury to the brain area for motor control might be discovered earlier and thus tumor resection can be performed safely.
