ABSTRACT

Headache in glioblastoma patients often indicates raised intracranial pressure by either tumor edema or tumor progression. We report local glioblastoma growth causing cranial nerve lesions as well as trigeminal neuralgia, and highlight pain management in these patients.

ABSTRACT

The primary tumor of brain metastases (BM) is unknown in up to one-half of BM at the time of neurosurgery. Fifty-four consecutive unselected BM were investigated immunohistochemically using antibodies against different intermediate filaments and tumor markers. By correlating the immunohistochemical results with the location of the primary tumor, a staining pattern characteristic of the most frequent BM could be established. Subsequently, 40 cases with known primary tumor were blinded and re-evaluated based on their immunohistochemical staining pattern. Lung (20.4%), colorectum (11.1%), melanoma (7.4%), and breast (7.4%) were the most common primaries. In 14 (25.9%) cases, the primary was unknown. The characteristic immunohistochemical profiles of BM were found to be positivity of cytokeratin 7 and thyroid transcription factor-1 (TTF-1) pointing to the lung, positivity of cytokeratin 20 and negativity of cytokeratin 7 pointing to the colorectum, positivity of vimentin and protein S100 and negativity of cytokeratins (CK) pointing to a melanoma, and positivity of cytokeratin 7 and CA 15-3 with negativity of TTF-1, CA 125 and CA 19-9 pointing to the breast. These primaries comprise the majority in our series. Using the established panel of immunohistochemical markers, we were able to identify the primary in 29 out of 40 (72.5%) BM correctly. To predict the primaries of BM, a combination of antibodies against different CK, vimentin, protein S100, TTF-1, and CA 15-3 is able to point to the primary site in BM of the unknown primary.

ABSTRACT

BACKGROUND: Fluorescence activated cell scanning (FACS) is a useful tool for identifying malignant cell clones of lymphoma cells in cerebrospinal fluid (CSF) by immunological phenotype. METHODS: We used FACS analysis for demonstrating it to be a quick and reliable technology that is available in most hematological laboratories. In this study, we demonstrate the clinical application of FACS analysis within a series of 15 lymphoma patients with suspected CSF involvement. CSF from three patients with another diagnosis than lymphoma serves as negative control. RESULTS AND CONCLUSION: A malignant cell clone cannot only be identified in CSF phenotypically, but also classified according to the immunological surface profile. As this method improves the diagnostic sensitivity and specificity, it should be implemented into routine diagnosis.

ABSTRACT

Epileptic seizures are common in patients with cerebral metastases as well as in patients with primary brain tumors. In cancer patients without primary brain tumors or brain metastasis, epileptic seizures may occur due to metabolic or toxic causes, or due to infections. We performed a retrospective analysis from our neurooncological database concerning the occurrence of seizures in patients with primary brain tumors, patients with cerebral metastases and in cancer patients without brain tumors. Patients with low grade gliomas, such as astrocytoma WHO I + II (69%), oligodendroglioma WHO II (50%), and mixed glioma WHO II-III (56%) were more likely to have seizures than patients with anaplastic glioma WHO III (44%), glioblastoma WHO IV (48%) or meningeoma (45%). In patients with brain metastasis, melanoma (67%), cancer of the lung (29%), and gastrointestinal tumors (21%) were the primaries with the highest frequency of seizures. In cancer patients without brain metastases or primary brain tumors, seizures occurred in 4%. In conclusion, the occurrence of epileptic seizures in patients suffering from primary brain tumors, as well as in patients with cerebral metastases, varied within the tumor entity. Therefore, especially in brain tumors where a higher probability of epileptic seizures is expected, they should be taken into account in the care of cancer patients.
