Project Summary:

Dr. Vijay Ramaswamy - 2017 Research Grant Recipient

Ependymoma is the third most common brain tumour of childhood and can occur anywhere in the brain and spinal cord. A major challenge in neuro-oncology is supratentorial ependymoma which arises in the hemispheres of the brain. Treatment currently consists of surgery and radiation, in children as young as 1 year.

Despite such aggressive therapy, many children still relapse and succumb to their tumour. Moreover survivors are left with lifelong disabilities and are frequently unable to live independent lives due to the effects of radiation on the developing brain. As such, new and novel treatments are urgently required.

This proposal seeks to bridge this gap by understanding why some supratentorial ependymoma’s are resistant to radiation and fail therapy. This will be done by studying the differences in supratentorial ependymoma from both diagnosis and after treatment failure, with the goal of identifying drugs that can be used to target the cause of treatment failure.

These drugs will be combined with radiation to determine if we can make radiation more effective, and even lower its dose. A potential result of this study is to help identify new treatment avenues to improve both survival and quality of life in children with supratentorial ependymoma.
