Diagnostic value of circulating tumor cells in cerebrospinal fluid
OBJECTIVE To assess circulating tumor cells in cerebrospinal fluid as a diagnostic approach to identify meningeal metastasis in patients with non-small cell lung cancer by using tumor marker immunostaining-fluorescence in situ hybridization (TM-iFISH). METHODS In 5 non-small cell lung cancer patients who were confirmed to have developed meningeal metastasis by cerebrospinal fluid cytology, 20...
متن کاملCytology of cerebrospinal fluid: technical and diagnosis considerations.
The usefulness of cerebrospinal fluid cytology in the diagnosis of malignancy has been enhanced in recent years by the development of new techniques for increasing cellular yield. Micropore filters and a specially adapted cytocentrifuge have been used for this purpose with a resulting increase in cell concentration and in diagnostic accuracy. Cerbrospinal fluid examination has been found to be ...
متن کاملMalignant cells in cerebrospinal fluid (CSF): the meaning of a positive CSF cytology.
We reviewed the correlation between malignant cells in cerebrospinal fluid (CSF) (positive cytology) and pathologic findings at autopsy. The purpose was to discover: (1) the incidence of negative CSF cytology in patients with CNS malignancy, (2) the incidence of false-positive cytology, and (3) the relationship between a true-positive cytology and the distribution of malignant tumor at autopsy....
متن کاملBlood-stained cerebrospinal fluid: traumatic puncture or haemorrhage?
Computed tomography fails to ascertain, or exclude, the presence of intracranial haemorrhage in a considerable number of cases, especially in subarachnoid haemorrhage and haemorrhagic infarcts. A number of other methods, including cerebrospinal fluid spectrophotometry and cytology have, therefore, been tested to define their diagnostic efficacy in 25 cases of confirmed intracranial haemorrhage ...
متن کاملLiquid-Based Cytology of the Cerebrospinal Fluid in a Case of Cryptococcal Meningitis
Cryptococcus neoformans is the most common microorganism found in cerebrospinal fluid (CSF) cytology and causes life-threatening infections in immunocompromised hosts. Although its cytomorphologic features in conventional smear cytology have been well described, those in liquid-based cytology have rarely been. A 73-year-old woman with diffuse large B-cell lymphoma presented with mental confusio...
متن کاملMalignant meningitis: a rational approach to cerebrospinal fluid cytology.
AIM To clarify laboratory guidelines for cerebrospinal fluid (CSF) cytology. METHODS Clinical and pathological data relating to 54 patients with cytologically malignant cells in the CSF were reviewed, together with CSF cell counts and protein measurements for 29 patients. Utilising this data, criteria were established for CSF cytology and validated by review of 100 patients in whom CSF cytolo...
