Onconeuronal antibodies p/Ri bodies (IB)

Onconeuronal antibodies are found in syndromes of paraneoplastic syndromes (PAHs). These are autoimmune disorders accompanying neoplastic diseases. Onconeuronal antibodies Anti-Ri are associated with breast cancer, small cell lung cancer a also with tumors of the reproductive system. Associated symptoms can be opsoclonus-myoclonus syndrome, brainstem inflammation or degeneration of the cerebellum. The presence of onconeuronal antibodies in the blood not infrequently precedes the symptoms of the cancer itself. The test should be performed in patients with a history of symptoms of PTSD and a history of cancer history. In addition, the assay should be performed in patients with PMS symptoms in whom there is no other cause for the presence of the disorder.
