Deletions of chromosomes 1p and 19q are associated with chemosensitivity and enhanced survival in oligodendrogliomas. Therefore, we have utilized FISH analysis as an ancillary tool for diffuse gliomas with suspected oligodendroglial features. To date, 246 gliomas have been analyzed in 131 male and 93 female patients, including 109 oligodendrogliomas (O), 109 mixed oligoastrocytomas/equivocal gl...
Primary spinal cord oligodendrogliomas are rare tumors comprising two percent of all spinal cord tumors. Although a treatment guideline has yet to be established, maximal surgical resection is primary in the treatment of spinal cord oligodendrogliomas. Adjuvant radiotherapy has remained controversial, and it is unclear whether chemotherapy adds any benefit. In this case report, the authors pres...
1p/19q FISH testing used for detecting loss of function 1p and 19q deletions in glial brain tumors has diagnostic and prognostic value. Because large or whole-arm deletions of chromosomes 1p and 19q are highly specific for oligodendroglioma, 1p/19q deletion testing is useful to distinguish oligodendrogliomas from astrocytomas, clear cell ependyomas, central or extra ventricular neurocytomas, an...
Astrocytomas, oligodendrogliomas, and oligoastrocytomas, collectively referred to as diffuse gliomas, are the most common primary brain tumors. These tumors are classified by histologic similarity to differentiated astrocytes and oligodendrocytes, but this approach has major limitations in guiding modern treatment and research. Lineage markers represent a potentially useful adjunct to morpholog...
