- n. A glioma believed to originate from the oligodendrocytes of the brain or from a glial precursor cell.
So, you know, this is the glioblastoma, which a lot of people have said speculatively, that the prognosis was worse than something like what's known as an oligodendroglioma, which is a different sort of tumor.
The tumor, her doctors felt, was malignant (though it was probably an oligodendroglioma, of relatively low malignancy) and needed to be removed.
They created the map by sequencing protein-coding genes in seven samples of tissue from oligodendroglioma tumors, and concentrated on recurring mutations in two genes CIC and FUBP1 not previously associated with those types of tumors.
The scientists say that they could not compare survival data in oligodendroglioma patients, because there were too few tumors that did not carry the mutations.
A total of 133 patients with anaplastic astrocytoma (AA, n = 56), anaplastic oligodendroglioma (AO, n = 67), or anaplastic oligoastrocytoma (AOA, n = 10) were included in the study.
It was several more weeks before it was confirmed that the tumor was a third-stage anaplastic oligodendroglioma, a rare type of brain cancer.
