本文报道36例中枢神经系统种肿瘤的脑脊液细胞学检查结果,即原发性肿瘤的肿瘤细胞的阳性检诊率为11.54?,转移性肿瘤为80%。尤以脑膜癌病的阳性检诊率最高达100%。此外,还发现脑脊液中单核样细胞及激活型单核细胞计数的增高是中枢神经系统肿瘤,特别是转移性肿瘤的脑脊液细胞学特征之一。因此,脑脊液细胞学检查对中枢神经系统转移性肿瘤有很大的诊断价值。本文并结合文献对上述问题进行了讨论。
This article reported the results of cerebrospinal fluid cytology in 36 cases of central nervous system tumors, that is, the positive rate of tumor cells in primary tumors was 11.54?, and metastatic tumors were 80%. In particular, the positive rate of meningeal cancer is as high as 100%. In addition, it has also been found that an increase in the count of mononuclear-like cells and activated monocytes in cerebrospinal fluid is one of the cytological features of cerebrospinal fluid in central nervous system tumors, especially metastatic tumors. Therefore, cerebrospinal fluid cytology is of great diagnostic value for metastatic tumors of the central nervous system. This article and the literature discuss the above issues.
