Anaplastic astrocytomas are a specific type of astrocytoma, and also belong to the broader category of gliomas – tumors that arise from glial cells. This is because astrocytes are a type of glial cell. For this reason, anaplastic astrocytomas (grade III) may also be called a “grade III glioma” or “high-grade glioma.”
How long can you live with a grade 3 astrocytoma (anaplastic astrocytoma)? One study reported the five-year survival rate for a grade 3 astrocytoma is 52% to 58%. Your life expectancy improves if treatment can completely remove the tumor.
Longer-term survivors of anaplastic astrocytoma do exist, and researchers have learned that their tumors usually have molecular features that predict better outcomes. In Rodney's case, his astrocytoma had a mutation of a protein known as “IDH” – patients with an IDH mutation generally have better outcomes.
While we always try to take out as much of the tumor as possible, most anaplastic astrocytoma tumors can't be removed entirely because they tend to intrude on or near healthy tissue. Outcomes generally improve when the tumor is more completely removed.
Is astrocytoma cancer curable? Surgery can cure most grade 1 astrocytomas if your neurosurgeon can safely remove the entire tumor. Very rarely, surgery may also cure some grade 2 astrocytomas. There's no cure for grade 3 and grade 4 astrocytomas, as they grow and spread quickly.
Despite the advancements, median survival, especially for Grade 4 gliomas and for glioblastomas doesn't exceed 12–18 months from diagnosis [10]. A very small percentage of cases showed >3 years survival, in other words long-survival.
“Glioblastoma is the most aggressive type of brain cancer and considered to be advanced by the time of diagnosis,” said Dr. Solmaz Sahebjam, a neuro-oncologist at Moffitt Cancer Center. “Currently it is not curable, meaning there's no way to eradicate all cancer cells.
The average survival time for a grade 4 astrocytoma is 12-18 months. Sadly, only 25% of people with a grade 4 astrocytoma survive more than one year, and only 5% survive more than five years.
The incidence of anaplastic astrocytoma (AA) is ∼0.48 per 100 000 person/years, making it much less common than glioblastoma multiforme (GBM).
High-grade astrocytoma
It is common for this tumour to come back after treatment. Further treatment is often needed.
