Paraneoplastic neurological syndrome in systemic cancer

Paraneoplastic syndrome refers to a group of disorders caused by or associated with cancers that are not direct effects of the primary tumor mass or a metastasis to the involved organs. Neurologically, the phrase describes a group of disorders that are diagnosed with increasing frequency in cancer patients. In this study, we investigated 36 patients with malignant diseases and various neurological paraneoplastic syndromes. Lung cancer is the most frequent malignancy associated with neurological paraneoplastic syndromes, and polyneuropathy is the most important manifestation among them.
