Abstract
✓ The authors report a study in which 109 cerebrospinal fluid (CSF) specimens from patients with varying neurological disorders were incubated in tissue culture medium for 1, 3, and sometimes 7 days. Strict criteria for malignancy were applied to cells found at these intervals. In 35 patients with verified central nervous system neoplasms, eight cases had malignant cells and 11 others had “doubtful” cells by tissue-culture analysis. Thirty-three of these cases were also examined with standard millipore cytological techniques: six had malignant cells and four had “doubtful” cells. Of 50 cases with inflammatory or other non-neoplastic conditions, cells were cultured in 13. None was considered malignant by our criteria. Tissue culture of CSF has several potential benefits. Even with stringent criteria, it is possible to demonstrate the presence of unequivocally malignant cells in CSF by tissue culture. The systemic application of such criteria may eventually increase the positive identification of malignancies. Further, since these cells are growing, the degree of malignancy may be more accurately determined by a study of growth in culture. Such a study could not be done by conventional methods. Finally, tissue culture can help to guide therapy in certain instances in which a surgical biopsy cannot be obtained.
