Summary
This phase III trial studies the side effects of combination chemotherapy, 3-dimensional conformal radiation therapy, and an autologous peripheral blood stem cell transplant, and to see how well they work in treating young patients with atypical teratoid/rhabdoid tumor of the central nervous system. Giving high-dose chemotherapy before an autologous peripheral blood stem cell transplant stops the growth of cancer cells by stopping them from dividing or killing them. Giving colony-stimulating factors, such as G-CSF, helps stem cells move from the bone marrow to the blood so they can be collected and stored. Chemotherapy or radiation therapy is then given to prepare the bone marrow for the stem cell transplant. The stem cells are then returned to the patient to replace the blood-forming cells that were destroyed by the chemotherapy or radiation therapy.
Eligibility Criteria
Inclusion Criteria
- Diagnosis of CNS atypical teratoid/rhabdoid tumor (AT/RT) or tumors that have a mutation of the INI1 gene (even if the tumor does not have the usual histologic characteristics of AT/RT)

- Patients with MRI evidence of spinal disease are eligible
- Must have undergone definitive surgery in the past 31 days

- Post-operatively, cranial MRI (with and without gadolinium) must be done, preferably within 48 hours of surgery or 10-28 days after surgery
- Entire spinal MRI must be obtained either pre-operatively (with gadolinium) or post-operatively (10-28 days after surgery), prior to study enrollment (with and without gadolinium)
- Life expectancy > 8 weeks
- ANC > 1,000/uL
- Platelet count > 100,000/uL (transfusion independent)
