What is the prognosis for medulloblastomas?

A Answers (1)

  • After undergoing medulloblastoma treatment, your child's prognosis depends on their level of risk. Your child's risk is categorized as average if the entire tumor - or most of it - was taken out during surgery, the tumor was in the back of your child's brain, and the tumor did not spread to other areas in your child's body. Your child's risk is categorized as high if some of the tumor was not taken out during surgery, the tumor was not in the back of your child's brain, and it spread to another area in your child's brain, spinal cord, or another location in their body.

    If your child is over three years of age and is categorized as average-risk, the likelihood that they will be free of cancer for five years is 80 percent. The likelihood drops to 50 to 60 percent if they are categorized as high-risk. For those children three years of age and younger, the survival rate is poor. For many of these children - approximately 40 percent - the tumor spreads.
