May be asking a lot with that comment, but here's the prognosis:
WHO grading system for astrocytomas WHO Grade 1 — e.g., pilocytic astrocytoma WHO Grade 2 — e.g., diffuse or low-grade astrocytoma WHO Grade 3 — e.g., anaplastic (malignant) astrocytoma
WHO Grade 4 — glioblastoma multiforme (most common glioma in adults) The prognosis is the worst for grade 4 gliomas, with an average survival time of 12 months. Overall, few patients survive beyond 3 years.
I once took a friend with a brain tumor to Mayo’s. They told me that she would likely live a year with surgery and radiation. She was dead four months later.
