Malignant astrocytoma is also known as or subsumes High-grade astrocytoma, Anaplastic astrocytoma, Giant cell astrocytoma, and Glioblastoma multiforme. -ed
The term "malignant astrocytoma" includes glioblastoma and anaplastic astrocytoma. Glioblastoma is the most common glioma in adults, with approximately 10,000 new cases diagnosed yearly in the United States. Unfortunately glioblastoma is also the most lethal primary brain tumor in adults. Anaplastic astrocytoma is less common than glioblastoma and carries a somewhat better prognosis, but it still leads almost invariably to a fatal outcome. There have been tremendous advances in the understanding of the cell biology and molecular genetics of malignant astrocytomas in the past 15 years. This new knowledge is slowly but steadily leading to new therapeutic strategies. In this clinical article, Dr. Edward Dropcho of the Indiana University Cancer Center reviews the biology, diagnosis, work-up, prognosis, current patient management, and future therapies for malignant astrocytoma.
