BACKGROUND
Identification of neoplastic cells in cerebrospinal fluid (CSF) by cytological analysis is the key diagnostic feature of leptomeningeal metastasis (LM). Because of the lack of sensitivity of this test, considerable efforts have been made to identify alternative diagnostic markers. Data
This study examined the diagnostic and prognostic value of vascular endothelial growth factor (VEGF) levels in the cerebrospinal fluid (CSF) of 39 patients with leptomeningeal metastasis (LM). Vascular endothelial growth factor levels at diagnosis were significantly higher in patients with LM
The topoisomerase I inhibitor, 9-nitro-camptothecin (9NC), is highly tumoricidal against glioblastoma multiforme (GBM) in vitro. However, systemic administration of 9NC has not shown the expected efficacy in clinical trials. This failure may be due to the rapid hydrolysis of 9NC in plasma from the
OBJECTIVE
To investigate the diagnostic value of transforming growth factor beta(1) (TGFbeta(1)), vascular endothelial growth factor (VEGF), urokinase-type plasminogen activator (uPA), and tissue-type plasminogen activator (tPA) in CSF for leptomeningeal metastasis (LM).
METHODS
The authors measured
This case study reports on a 56-year-old woman with breast adenocarcinoma and leptomeningeal metastases. After initial chemotherapy with a dose-dense regimen of doxorubicin/cyclophosphamide followed by 3 cycles of docetaxel (100 mg/m(2)), a lumpectomy was performed that revealed invasive ductal
BACKGROUND
Chemotherapeutic effects in leptomeningeal carcinomatosis (LC) vary widely between patients, presumably in part because drug elimination from cerebrospinal fluid (CSF) differs between individuals. An individual dosing, adapted to elimination, may improve treatment efficacy.
OBJECTIVE
To
The aim of the present study was to discuss a novel method for the detection of malignant tumor cells in cerebrospinal fluid (CSF), by observing tumor marker-immunostaining fluorescence in situ hybridization (TM-iFISH) enrichment and by counting CSF malignant tumor cells in patients with lung cancer
OBJECTIVE
To determine the value of vascular endothelial growth factor (VEGF) in CSF as a marker for carcinomatous meningitis (CM).
METHODS
The concentration of VEGF was measured by ELISA in matched samples of CSF and serum collected from 162 patients. These included patients with solid tumors with
Background: Metastatic spread into the cerebrospinal fluid (CSF) represents a severe complication of malignant disease with poor prognosis. Although early diagnosis is crucial, broad spectrums of clinical manifestations, and pitfalls of magnetic resonance imaging (MRI) and CSF diagnostics can
In this single-center retrospective study, 155 consecutive patients with leptomeningeal metastasis (LM) were analyzed for the prognostic role of patient- and therapy-related variables. Ten percent of the patients received radiotherapy alone, 32% had chemotherapy alone, 31% received
Beta2-Microglobulin ( β 2-m) is a low molecular weight protein occurring in all body fluids. Its concentration increases in various pathologies. Increased values in cerebrospinal fluid (CSF) are ascribed to an activation of immune system. Using immunoturbidimetry, we examined concentrations of
BACKGROUND
Prognosis assessment of patients with infectious and neoplastic disorders of the central nervous system (CNS) may still pose a challenge. In this retrospective cross-sectional study the prognostic value of basic cerebrospinal fluid (CSF) parameters in patients with bacterial meningitis,
Modification of an enzyme immunoassay using beads as solid phase allows the detection of 3 pg/ml carcinoembryonic antigen (CEA). The beads are shown to be advantageous for the extraction of proteins in highly diluted antigen solutions thus replacing a need for concentration of the sample. The mean
Neoplastic meningitis due to the dissemination of systemic cancer or primary central nervous system tumors through the cerebrospinal fluid carries a very poor prognosis. Current treatments for this disease are ineffective, and new therapeutic modalities such as immunotoxins may be beneficial. We
BACKGROUND
Ifosfamide remains one of the major cytotoxic drugs for sarcoma management. Ifosfamid-related encephalopathy (IRE) is a rare but severe adverse event, without clearly identified risk factors.
METHODS
We have carried out a single-center, retrospective study to assess the occurrence and the
