Full textBackground: Paraneoplastic cerebellar degeneration (PCD) are rare autoimmune disorders affecting an otherwise immune-privileged site: the central nervous system. This autoimmunity is associated with the presence of a cancer and is satellite of the anti-tumor immune response, the B-cell response originating a secretion of autoantibodies that are diagnostic hallmarks of these disorders. These autoantibodies are directed against a protein expressed both in the tumor and in the CNS, the so-called onconeural antigen. The triggers of the immune tolerance breakdown and the exact relationship between the tumor, the immune system and the neurological symptoms are still not totally understood. Recent studies have allowed to show that in some tumors associated with paraneoplastic syndromes (namely ovarian and breast cancers associated with Yo syndrome), the onconeural antigen is overexpressed due to the presence of a gain or amplification in the gene locus and may present mutations while in others, none of these alterations of the onconeural antigen are present (e.g. lung cancers in Hu syndrome). The objectives of this thesis work are to further analyze the link between the tumor and the paraneoplastic autoimmunity by comparing two syndromes associated with the same type of cancer (Ri and Yo syndrome associated with breast cancers, RGS8 and DNER syndrome associated with Hodgkin’s lymphoma) and to search for antigen alterations in another syndrome (Ri syndrome).Methods: we conducted two studies within the frame of this thesis work. A first study on a clinical and pathological cohort of breast cancers associated with Ri-syndrome using clinicopathological data, DNA-sequencing, and whole-transcriptome analysis. A second analysis on three patients with RGS8-syndrome using clinicopathological data and Phage Immunoprecipitation sequencing (PhIP-seq).Results: Ri breast cancers were a subtype different than one observed in Yo with uncommon genetic features that singularize them among their subtype. Neither overexpression nor genetic alteration of the Ri onconeural antigens were found in Ri breast cancers. Conversely, the anti-tumor immune reaction in Ri breast cancers was similar to the one found in Yo: an atypical intratumoral B-cell infiltration.Concerning RGS8 paraneoplastic cerebellar degeneration, two patients presented with a Hodgkin lymphoma of the rare specific subtype called nodular lymphocyte-predominant Hodgkin lymphoma, whereas DNER is associated with the classical nodular-sclerosing form. Autoantibodies detected in all patients enriched the same epitope on the RGS8 protein, which is an intracellular protein physiologically expressed in Purkinje cells but also ectopically expressed specifically in lymphoma cells of patients with RGS8-syndrome.Conclusion: each paraneoplastic syndrome is associated with a specific histomolecular subtype of cancer with uncommon genetic features, which provides the first evidence of a tight link between oncogenesis and paraneoplastic immunity. Alterations of the antigen (overexpression, copy number variation and mutation) may be the mechanism of immune tolerance breakdown in several different syndromes but are not ubiquitous. The antitumor immunity seems to be an atypical B-cell response in several subtypes irrespective of the tumor type and antigen alterations. These results are a step forward in our understanding of paraneoplastic immunity and provide clues on potential predictive markers of paraneoplastic immunity that may be of use in personalizing medical decision of immunotherapy in the field of oncology
