Paraneoplastic syndromes can affect any portion of the nervous system, either a single area or cell type (e.g., Purkinje cells of the cerebellum) or cause more widespread damage (e.g., encephalomyelitis). This paraneoplastic syndrome precedes most cancer-specific symptoms by several months or years before tumors become radiologically detectable. They are caused by mechanisms other than metastasis or by any of the complications of cancer such as coagulopathy, stroke, metabolic and nutritional conditions, infections, and side effects of cancer therapy. The paraneoplastic endocrine syndromes generally result from tumor production of hormones or peptides that lead to metabolic derangements. Paraneoplastic neurologic syndromes are a heterogeneous group of neurologic disorders caused by mechanisms other than metastases, metabolic and nutritional deficits, infections, coagulopathy, or side effects of cancer treatment.
