This phase III trial is studying giving combination chemotherapy together with 3-dimensional conformal radiation therapy and an autologous peripheral blood stem cell transplant to see how well it works 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.

Primary Outcome Measures:
  • Event-free survival [ Time Frame: Time to disease progression, disease relapse, occurrence of a second malignant neoplasm, or death from any cause, assessed up to 4 years ] [ Designated as safety issue: No ]
    For statistical evaluation and data reporting, the study cohort can be regarded as comprising four different strata. A one-sided log-rank test with 5% Type I error rate will be used for stratum I. For patients in strata II through IV, Kaplan-Meier estimates of disease control (event-free survival) and overall survival will be computed and compared to that in stratum I. The comparison with Stratum I will be largely descriptive.

  • Overall survival (S) of patients with histologically and/or molecularly diagnosed AT/RT [ Time Frame: Time to death from any cause, assessed up to 4 years ] [ Designated as safety issue: No ]
    The outcome of very young patients (<3 years of age) on this study whose histologic diagnosis is AT/RT will be compared with infants identified as having AT/RT on POG 9233 and CCG 9921. For patients in strata II through IV, Kaplan-Meier estimates of disease control (event-free survival) and overall survival will be computed and compared to that in stratum I.

  • Toxic death [ Time Frame: During and after completion of study treatment ] [ Designated as safety issue: Yes ]
    Treatment-related death is defined as death primarily attributable to complications of treatment.

Secondary Outcome Measures:
  • Overall toxicities as assessed by the National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE) version 4.0 [ Time Frame: During and after completion of study treatment ] [ Designated as safety issue: Yes ]
    The occurrence of grade 4 ototoxicity, electrolytic wasting (acidosis), hemorrhagic cystitis, non-hematologic toxicity, or gastrointestinal/mucositis toxicity (defined as mucositis toxicity associated with life-threatening consequences).

Enrollment: 70
Study Start Date: December 2008
Primary Completion Date: April 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Treatment (chemotherapy, 3D-CRT, autologous PBSC)

Patients receive vincristine IV on days 1, 8, and 15; high-dose methotrexate IV on day 1; leucovorin calcium orally or IV; etoposide IV on days 4, 5, and 6; cyclophosphamide IV on days 4 and 5; cisplatin IV on day 6*; and G-CSF IV or SC on day 7 until ANC recovers.

Within 2-6 weeks after induction therapy or radiation therapy, patients receive high-dose carboplatin IV and high-dose thiotepa IV on days 1 and 2 and undergo autologous PBSC rescue on approximately day 4. Patients also receive G-CSF IV or SC once daily until ANC recovers. Treatment with consolidation therapy followed by stem cell rescue repeats every 28 days for 3 courses in the absence of disease progression or unacceptable toxicity. Before (but after induction therapy) or after consolidation therapy and stem cell rescue, patients undergo 3D-CRT to the brain (and the spine if needed) 5 days a week for 5-6 weeks.
