Paraneoplastic syndromes

Abstract: There are two types of clinical and biochemical syndromes not directly associated with the invasiveness and metastatic ability of the tumour; the first type is represented by the hormonal paraneoplastic syndromes. The second type consists of certain neurological diseases or abnormalities observed in patients with malignant tumours not directly affecting the nervous system. While the hormonal type is well established and rests on solid ground, the neurological type is less well defined and more controversial. © 1981 Pergamon Press Ltd.
