Sažetak
Several markers have been studied for their ability to make the central nervous system (CNS) infiltration diagnosis earlier and more precise. We investigated the measurement of D-dimer in cerebrospinal fluid (CSF) and evaluated them as a potential biomarker of neoplastic infiltration within the CNS. The study was performed on 87 CSF samples divided into three groups: patients with carcinoma (n=10) and different lymphoid malignancies (n=43) with clinical or biological evidence of CNS involvement, and controls (unsolved headache) (n=34). D-dimers were measured by VIDAS automated immunoassay system. Cell counts were performed by optical microscopy (Fuchs-Rosenthal chamber), and glucose, lactate and total proteins were determined by standard tests on Beckmann automated analyzer. Highly increased levels of D-dimers (mean=3.80 mg/L) were demonstrated in all CSF samples from patients with carcinoma, but in group of patients with lymphoid malignancies increased levels of D-dimer were found only in 32% CSF samples, andthe values were lower (mean=0.52 mg/L). In all control CSF samples, D-dimer values were <0.05 mg/L. Although this test is not specific for neoplastic affections, our preliminary data suggest that the measurement of D-dimers in CSF may be useful in the diagnosis of CNS involvement of neoplastic cells, especially in patient with carcinoma, and also in monitoring intrathecal therapy.
