| Anaplastic astrocytoma is a type of aggressive tumor that affects the central nervous system. |
| Of the 14 anaplastic oligoastrocytomas, 6 were designated astrocytoma predominant and 2 were oligodendroglioma predominant. |
| The astrocytoma was well defined and had only partially infiltrated surrounding tissue. |
| Similar results were seen when cases of astrocytoma were analyzed separately. |
| I can attest to those age groups because my brother died of an astrocytoma, which is a malignant brain cancer. |
| In 1989, Susan Elen Reynard, then 31, was told she had a malignant astrocytoma, a brain cancer that occurs in about 6,000 adults in America each year. |
