[The diagnostic value of immunoglobulin G in the cerebrospinal fluid of brain tumor patients, particularly in malignant tumors].
The diagnostic value of immunoglobulin G in cerebrospinal fluid (CSF-IgG) has been evaluated in patients with brain tumors. The (CSF-IgG) level in patients with malignant brain tumors was found to be significantly elevated when compared to the level in control patients without a disorder of the central nerve system. Especially significant was high level of CSF-IgG found in patients whose tumor had invaded into ventricles. The CSF-IgG level was found to decrease to a normal range by a total or subtotal resection of the tumor, but not by partial resection. On the other hand, CSF which contained large amount of IgG inhibited the lymphocyte proliferative response to phytomitogen. These results suggest that CSF-IgG seems to correlate with the tumor volume, and is important as a tumor marker in patients with a malignant brain tumor.
