CNS831: Phase III Randomized Trial of Maintenance Chemotherapy Versus Observation in Pediatric Patients (ages 1 to 21 yrs) With Newly Diagnosed Ependymoma Following Induction Chemotherapy and Post-Operative Radiation Therapy


Brain Tumor : Intracranial ependymoma


Ependymoma is a type of cancer that occurs in the brain and spinal cord. The current standard of treatment for newly diagnosed ependymoma includes surgery to remove as much of the tumor as possible followed by radiation therapy.

Recent studies of young children have shown that chemotherapy (anti-cancer drug therapy) can help shrink or get rid of ependymoma and may make it easier for surgeons to remove the tumor.

The goal of this study is to find out if alternative treatments for ependymoma are available, including surgery followed by observation, surgery followed by chemotherapy, possible second surgery followed by radiation and chemotherapy. Patients with favorable pathology and tumor location in the upper part of the brain will undergo observation only following surgery. All other patients enrolled will receive 7 weeks of chemotherapy followed by three options depending on the results from the post induction MRI imaging (details below).


In general, this study aims to determine the effects of surgery, radiation therapy and chemotherapy on learning, thinking, hearing and the production of hormones.
