Full textTractography and intraoperative stimulation would optimize tumor resection preserving the quality of life. The principles of diffusion tensor, tractography and brain stimulation are shown. A study of tractography of optic radiation and validation on a lesion model was able to confirm the feasibility of the reconstruction. Among the tested algorithms, the most effective was the "Tensor Line" predicting a risk of quadrantanopia when more than 5% of the trajectories have an intersection with the lesion volume. The second part focused on the cognitive process of language whose translation by cortical stimulation during awake surgery for 7 bilingual patients. Twenty-six interference tasks area were found but none was specific to the translation, which is complex to study. Finally, the prospects for integration of these 2 techniques are discussed through three clinical cases

Full textBackground: The clinical prognosis of glioblastoma, the most aggressive primary brain tumor in adults, remains poor (Stupp et al. 2005). Nanomedicine could provide new therapeutic tools to overcome current limitations. Au@DTTPA(Gd) gold-gadolinium hybrid nanoparticles are being studied for their radiosensitizing potential in vitro and in vivo (Alric et al. 2008 and Miladi et al. 2014). The main objective of this thesis work is to evaluate in vitro and in vivo the anti-invasive potential of Au@DTDTPA(Gd) associated with radiotherapy.Results: From 2D and 3D in vitro cell cultures, ex vivo organotypic cultures and in vivo cranial window model on the infiltrating line U251 and the radioresistant line U87, we evaluated the anti-invasive potential of Au@DTDTPA(Gd) nanoparticles with or without radiotherapy. Nanoparticles alone reduce the invasive capacity of U251 spheroids but are not related to MMP2 proteolytic activity and MMP14 expression. They also reduce the abilities of U251 cells to migrate both collectively and individually. At the same time, nanoparticles affect the biomechanical capacities of U251 cells, which are marked by an increase in the number and diameter of actin fibers at the level of cell protrusions, an enhanced membrane rigidity. These changes are associated with an increase in cell traction forces, expression of adhesion proteins and a decrease in the number of protrusions. All these data would explain the inhibition of cell motility of U251 cells by Au@DTTPA(Gd) nanoparticles. We then highlighted the effects of Au@DTDTPA(Gd) associated with different radiotherapy protocols on the radioresistant U87 cell line. The in vitro 3D, ex vivo and in vivo follow-ups indicate a decrease in the progression of U87 cells. We have developed a 3D in vitro model that allows the recovery of migratory cells from treated spheroids. After treatment, we observed that Au@DTDPA(Gd) alone or in combination with radiotherapy decreased the number of migratory cells, as well as their viability by induction of mitotic catastrophes. The combined treatment also decreased both the secretion and activity of MMP2 in migrating cells. Fluorescence microscopy observations reveal a loss of intercellular junctions and compromised expression of Cx43 in intercellular junctions. Culture of migratory cells in a neurosphere medium allowing stem cell selection showed that treated migratory cells form fewer neurospheres and have a reduced diameter. These results suggest that migratory cells would lose their stem-like characteristics.Conclusion: Our overall results suggest that Au@DTTPA(Gd) nanoparticles possess anti-invasive effects by disrupting the biomechanical capabilities of GBM cells. Moreover, Au@DTDTPA(Gd) combined with radiotherapy reduce the invasive properties of migrating GBM cells by inducing mitotic catastrophes, loss of intercellular junctions and attenuation of their stemness. These results show that Au@DTDTPA(Gd) and radiotherapy have therapeutic potential for future preclinical studies

Full textNeuropsychological sequelae associated with pediatric brain tumors represent a major public health issue.Disorders of executive functions have been identified among these children, but the nature of the impaired processes, recommended evaluation modalities and the impact of demographic and medical variables related to the disease remain unclear. The aim of this thesis was to get a broader understanding of the disturbance profile of the different executive processes in this disease context, comparing performance-based measures and daily life indicators (in both the school and home environment). From this perspective, we have 1) analyzed the executive profile of 171 school age children with a brain tumor in the BRIEF (Behavior Rating Inventory of Executive Function) and 2) examined the association of these indicators with performance-based measures adapted in French in 27 patients matched to healthy children. The influence of clinical variables on the executive profiles was discussed. Broad and variable executive difficulties have been identified in patients’ everyday life (all tumor types and locations) at home as well as school, with also increased difficulties reported by parents in the case of radiation therapy at an early age. Disturbances of executive control are confirmed in direct measures, whose convergence with the questionnaires appears however limited. Based on these results, respective contributions of these two types of tools are discussed in order to understand the executive issue in pediatric brain tumor survivors

Full textIn research and in clinics, pathologic states of the brain have been widely characterized, and new treatment strategies evolve on a daily basis. Conversely, therapy of one of the most severe brain conditions, known as glioblastoma, is in many cases without success. Within the therapeutic range, radiotherapy represents the most efficient method. However, as normal tissue cells are equally affected by radiation effects as cancerous cells, the prescribed dose remains greatly limited by radiotoxic adverse reactions. Thus, a continuous demand of improved irradiation techniques challenges researchers and clinicians to date. A novel form of radiotherapy is being developed, termed Microbeam Radiation Therapy (MRT). In MRT, X-rays are generated by a synchrotron light source and are collimated into an array of parallel microbeams that are a few tens of microns wide and separated by a few hundred microns. This irradiation geometry allows very high dose deposition in the microbeam paths (peak dose) while tissue slices located in-between these paths receive only 5-10% of the peak dose (valley dose). The major benefit of this new modality lies within the preferential effects on tumor than on normal tissues. Tumor vessel responses differ drastically from those observed in mature blood vessels, thus preserving normal tissues while successfully ablating cancerous cells. In this thesis, the effects of MRT on normal brain tissue were further investigated. First, normal rats were exposed to whole-brain MRT (valley doses from 7 to 25 Gy). Second, MRT was delivered through multiple ports (up to 5), focalized in the right caudate nucleus (10 Gy valley dose). These animals were subject to behavioral tests, magnetic resonance imaging (MRI) and histologic analysis until one year post exposure. Results were compared to untreated rats and animals exposed to hospital- or synchrotron-generated broad beam (BB) irradiation. In addition, the multiport MRT geometry was tested on 9L gliosarcoma-bearing rats. The results demonstrated that long-term normal brain tissue effects of MRT at valley doses higher than 10 Gy were not negligible. Chronic vascular effects started off this dose, whereas tissue necrosis was only observed after 25 Gy exposure. MRT-induced behavioral changes were seen in increased locomotion and exploratory drive. However, veterinary observations did not raise concern in rats irradiated with ≤17 Gy MRT valley dose or in rats exposed to the multiport configuration. Remarkably, the successive addition of MRT incidences to the standard protocol for 9L tumor treatment increased significantly and exponentially animal survival and tumor control. Indeed, multiport MRT increases biological equivalent doses by a factor of ~2.5, a result never achieved by any other radiotherapeutical approach. The exceptional normal tissue sparing and the outstanding therapeutic index make multiport MRT a promising innovative method that is primed for clinical translation

Full textDespite the constant efforts by neurosurgeons, the prognosis for the patients with a malignant primary brain tumours has changed minimally over the last three decades. Then the development of new animal models of glioma is necessary for in vivo evaluation of all new therapeutic propositions of this type of tumours. In the first part of our study, we realised an allogreffe model of cerebral tumours of the cell line C6-9. In the second part, our first target was to determine the usefulness of our model in the evaluation of the photochemotherapy by using the hematoporphyrine (HPD). Our second target was to study the efficacy of SIM01 (photosensitizer in stage of development) by comparing it to m-THPC which is in clinical trials in Europe, as for example in Nantes, and in USA. Through this study we obtained a reproducible simple model in a reasonable delay valid for the evaluation of in vivo photochemotherapy. It also presented SIM01 as a new promising molecule in the domain of the photochemotherapy
