Methotrexate and Etoposide Infusions Into the Fourth Ventricle in Children With Recurrent Posterior Fossa Brain Tumors
Summary
The main purpose of this protocol is to establish the safety of infusions of methotrexate and etoposide into the fourth ventricle of the brain or prior surgery location in patients with recurrent malignant posterior fossa brain tumors (small space near the brainstem and cerebellum). These tumors include medulloblastoma, ependymoma, atypical teratoid/rhabdoid tumor or other malignant brain tumor with recurrence or progression involving anywhere in the brain and/or spine. Patients' disease must have originated in the posterior fossa of the brain.
Trial Information
What to expect:
Once a patient has been confirmed to be eligible for study enrollment, and prior to beginning study treatment, all prior medical history will be reviewed, a physical and neurological exam will be completed, blood will be drawn and a lumbar puncture will be done to confirm that it is safe for the patient to receive study treatment and a MRI scan will be done of the brain and spine to check the patients disease.
Prior to beginning study treatment, patients will have surgery to place an Ommaya reservoir (special catheter to deliver the study treatment to the brain). The study doctor may also remove the tumor at the time of the surgery to place to Ommaya reservoir.
One the days the patient receives study treatment a neurological exam will be completed
Within a week of finishing study treatment, the patient will complete a neurological exam, a lumbar puncture and a blood draw, and will complete an MRI scan to check the status of the patient’s disease after completing treatment.
Patients will receive study treatment for a total of 6 weeks
Approach
Treatment:
Methotrexate: Patients will receive methotrexate through the Ommaya reservoir 2 days a week for 6 weeks (12 total treatments/infusions) . Each infusion will take about 3 minutes to complete.
Etoposide: Patients will receive etoposide through the Ommaya reservoir 5 days a week during treatment week 1, 3 & 5 (15 total treatments/infusions). Each infusion will take about 3-4 minutes to complete.
