Abstract
Paraneoplastic cerebellar degeneration (PCD) is a heterogeneous group of neurologic syndromes associated with primary tumors. It is postulated that the immune system targets a tumor antigen that is also expressed endogenously in the nervous system. The majority of these patients are diagnosed with breast cancer or gynecological cancer, while it is exceedingly rare in lung squamous cell carcinoma (LUSC) patients. Here we reported a rare case of anti-Yo antibody-positive PCD in a patient with LUSC and got successfully treated via immunotherapy and oncological treatment. The patient's ataxia symptoms alleviated following the administered treatments, suggesting that early immunotherapeutic intervention may have potential value in mitigating neurological deterioration. Furthermore, active and timely management of the primary carcinoma is crucial.
期刊介绍：
Frontiers in Immunology is a leading journal in its field, publishing rigorously peer-reviewed research across basic, translational and clinical immunology. This multidisciplinary open-access journal is at the forefront of disseminating and communicating scientific knowledge and impactful discoveries to researchers, academics, clinicians and the public worldwide.
Frontiers in Immunology is the official Journal of the International Union of Immunological Societies (IUIS). Encompassing the entire field of Immunology, this journal welcomes papers that investigate basic mechanisms of immune system development and function, with a particular emphasis given to the description of the clinical and immunological phenotype of human immune disorders, and on the definition of their molecular basis.
