Paraneoplastic neurological syndromes (PNSs) are a group of immune-mediated neurological disorders occurring in patients with systemic cancers which are associated with the presence of anti-neuronal antibodies. In this retrospective study, serum and cerebrospinal fluid of 489 patients were analyzed for the presence of well characterized onconeural antibodies. The 18 PNS patients positive for onconeural antibodies were reanalyzed to evaluate possible intrathecal synthesis. Intrathecal synthesis of onconeural antibodies, was detected in 10/15 patients affected by PNSs involving the CNS and in 1/3 cases with peripheral syndromes. Our data confirm that onconeural antibodies are produced within the CNS in most PNS patients. Evaluation of intrathecal synthesis of onconeural antibodies on a larger cohort of PNS patients and the correlation with disease course might elucidate whether this marker has a value in predicting the prognosis of the neurological disease.
