Identification of morphological and molecular predictive factors of recurrence in soft tissue sarcomas of the limbs and trunk wallSarcomas are rare malignant mesenchymal tumors that represent 2/100,000 new cases per year. They represent a heterogeneous group of tumors, generally associated with a poor prognosis. Surgical resection remains the only curative treatment. These tumors can recur even after optimal surgery, classified R0, i.e. without microscopic residue (in about 10% of cases). Different pathological prognostic factors are known, including initial tumor size, FNCLCC histological grade scheme and deep tumor location. At present, there is no available marker to predict the risk of recurrence following curative surgical resection of a sarcoma, which complicates the clinical decision making.So far, studies have focused on the features of tumor cells but the features of tissue margins surrounding sarcoma cells are unknown. The margin constitutes the interface between the tumor tissue and the healthy tissue, it is a remodeled tissue located in direct contact with the tumor cells. The mode of tumor cell infiltration differs from one tumor to another and could modulate or reflect the risk of local relapse. Interestingly, a molecular signature predictive of local relapse has been identified in hepatocellular carcinoma by studying of the “healthy tissue”, but no data is available in sarcomas. This thesis project aims at identifying predictive factors of local tumor relapse by systematically and comparatively studying the tumor and its peripheral zones, including the central tumor zone (Tc), peripheral tumor zone (Tp), healthy peritumoral tissue in contact tumor cells (HT-R1) and remote healthy tissue (HT) in a retrospective series of 144 soft tissue sarcomas.In a first part, we have characterized the immune infiltrate associated with sarcomas by systematically studying the tissue margin with a focus on tertiary lymphoid structures (TLS), a predictive factor of response to immunotherapy in sarcomas using microscopy and immunohistochemistry. The distribution of TLS predominates in the tumor margin and seems to be correlated with a better prognosis.The second part studied by deep learning (DL) the different tumor areas using scanned slides to highlight new unknown predictive morphological factors correlated with relapse and to establish a predictive Deep learning (DL) signature of local relapse. The DL score exceeds the survival curves associated with the FNCLCC grade; the current gold standard used to assess patient risk in clinical practice.A third approach compared the transcriptome of the different tumor areas determined by whole RNA-sequencing to identify deregulated biomarkers in the different areas and to determine the immunological signatures in the different territories. Genes of interest have been highlighted in the marginal zone that may be associated with the risk of relapse. Finally, a spatial transcriptomic analysis by Visium technique was carried out on a few cases on an exploratory basis.Our study has evidenced biomarkers correlated with a higher risk of relapse that could allow in the future to identify high risk patients to personalize their follow-up and validate complementary therapeutic modalities

Diffusion magnetic resonance imaging (dMRI) is a technique for the non-invasive characterization of the microstructure in biological tissues since it is sensitive for the diffusion processes of hydrogen molecules. dMRI is a promising candidate for in vivo quantification of neurite morphology in white matter. Over the past two decades, conventional dMRI method usually focused on Diffusion Tensor Imaging (DTI). DTI was widely used to assess the organization of tissue in white matter, providing some indices to describe changes in biology. The model of DTI describes the diffusive water molecules relevant to free diffusion or hindered anisotropic diffusion homogeneous within each voxel based on the assumption of Gaussian distribution. However, DTI was obtained at single b-value and lacked of specificity for describing tissues in this assumption. Additionally, several advanced dMRI techniques, especially multi-compartment models, have been proposed with complicated assumption for estimating neuron morphology. Neurite Orientation Dispersion and Density Imaging (NODDI) is a clinically feasible technique for estimating the microstructural complexity in central neuron system imaging, post by Zhang et al. in 2012. NODDI is a multi-compartment tissue model based on dMRI, combining a three-compartment tissue model: restricted compartment for non-Gaussian anisotropic diffusion (referring to the space bounded by the membrane of neurites), hindered compartment for Gaussian anisotropic diffusion (referring to the space around the neurites) and isotropic compartment for Gaussian diffusion (referring to the CSF space) in each voxel. Using three compartments, NODDI map not only axons in the white matter but also dendrites in gray matter in each voxel. Compared to DTI indices, NODDI may provide greater specificity to morphology and pathology, e.g. neurite density and orientation dispersion. The aims of this work are to explore the promising indices of diffusion models in characterizing the microstructural complexity in the peritumoral area of gliomas and to show the clinical feasibility and potential capability of NODDI studies. The first chapter gave an overview of dMRI and explained the models of NODDI as well as DTI (Chapter 1). In the chapters 2~5, we investigated the different preprocessing interference on NODDI and DTI as verified by topography of corpus callosum for optimization (Chapter 2), and then we differentiated different types of gliomas and characterized the infiltration in peritumoral area by NODDI and DTI using the optimized preprocessing method (Chapter 3); furthermore, we in-vivo evaluated the simplified NODDI imaging protocol and constructed the semi-automatic regions of interest (ROI) delineation for peritumoral areas (Chapter 4 and 5). Finally, the last chapter gave a conclusion of this thesis (Chapter 6).
