<unk>  <unk>  is a<unk>  syndrome associated with a broad variety of tumors including lung cancer, ovarian cancer, breast cancer, Hodgkin’s lymphoma and others.<unk>  is a rare condition that occurs in less than 1% of cancer patients. As is the case with other<unk>  syndromes,<unk>  is believed to be due to an autoimmune reaction targeted against components of the central nervous system, mostly to Purkinje cells. It is thought to be triggered when tumor cells (in<unk> , most commonly ovarian or breast cancer) ectopically express proteins normally expressed in the cerebellum. This is believed to trigger an anti-tumor immune response that may be clinically significant, but also an anti-neural immune response. A broad spectrum of neuronal and glial proteins has been identified as target antigens in<unk> .
