Abstract
• Cerebrospinal fluid (CSF) carcinoembryonic antigen (CEA) values were determined in 200 patients suffering from various neurological diseases. We found no relationship between CEA levels and age or sex. A positive test was defined as an upper limit of at least 4.0 ng/mL of CEA. We found raised CSF CEA levels in patients with leptomeningeal spread from carcinoma, but not in patients with leptomeningeal metastases from lymphoma. We also found high values of CSF CEA in three of 21 patients with epidural metastases and in two of 28 patients with cerebral metastases from solid tumors. Comparison was made with the CSF levels of total protein, glucose, and lactate dehydrogenase. The sensitivity of the CSF CEA determination in patients for the presence of leptomeningeal involvement of cancer is 31% and the specificity is 90%.
