Drugs used in chemotherapy, such as vincristine, cisplatin, and cyclophosphamide, work in
different ways to stop tumor cells from dividing so they stop growing or die. Radiation
therapy uses high-energy x-rays to damage tumor cells. Combining radiation therapy with
chemotherapy may kill more tumor cells. Autologous stem cell transplant may be able to
replace blood-forming cells that were destroyed by chemotherapy or radiation therapy. It is
not yet known which radiation therapy regimen combined with chemotherapy and donor stem cell
transplant is more effective in treating medulloblastoma, supratentorial primitive
neuroectodermal tumor, or atypical teratoid rhabdoid tumor.
This phase III trial is studying two different regimens of radiation therapy when given
together with chemotherapy and autologous stem cell transplant to see how well they work in
treating patients with newly diagnosed medulloblastoma, supratentorial primitive
neuroectodermal tumor, or atypical teratoid rhabdoid tumor.
PRIMARY OBJECTIVE:
- To assess the relationship between ERBB2 protein expression in tumors and
progression-free survival probability for patients with medulloblastoma.
- To estimate the frequency of mutations associated with SHH and WNT tumors (as defined by
gene expression profiling) via targeted sequencing performed in an independent cohort of
WNT and SHH tumors (also defined by gene expression profiling).

SECONDARY OBJECTIVES:
- To compare the effects of a computer-based training system specifically targeting
language, reading, and learning skills (Fast ForWord, Scientific Learning Corporation)
with the current standard of care on reading decoding skills as measured by individual
academic testing.
- To monitor for treatment failure in the posterior fossa of patients whose tumor bed
receives a reduced volume of radiation.
- To correlate radiation dosimetry of target and normal tissues with rate and patterns of
failure and longitudinal measures of audiometric, endocrine and cognitive effects.
EXPLORATORY OBJECTIVES:
- To estimate the change in neuropsychological performance from the neuropsychology
assessment battery (intellect, academic achievement and cognitive ability) and examine
the relationship of these changes to risk group, age at diagnosis, and parent measures.
- To evaluate the differences between neurotoxicity in the average-risk patient group with
that in the high-risk group through qMRI, and fMRI.
- To develop or refine novel models relating impact of medulloblastoma therapy on
neurocognitive performance to quantitative and functional neuroimaging measures.
OUTLINE: This is a multicenter study. Patients are stratified according to disease risk
(high-risk disease vs average-risk disease).
Patients in both strata undergo peripheral blood stem cell or bone marrow harvest.
- Stratum 1 (high-risk group):
- Radiotherapy: Patients undergo craniospinal radiotherapy once daily 5 days a week
for 6 weeks.
- High-dose chemotherapy and autologous stem cell transplantation (SCT): Six weeks
after the completion of radiotherapy, patients receive high-dose chemotherapy
comprising vincristine IV followed by cisplatin IV over 6 hours on day -4 and
cyclophosphamide IV over 1 hour on days -3 and -2. Patients undergo autologous SCT
on day 0. Patients receive filgrastim (G-CSF) subcutaneously beginning on day 1 and
continuing until blood counts recover. Patients receive vincristine IV on day 6.
High-dose chemotherapy and autologous SCT repeat every 4 weeks for 3 additional
courses in the absence of unacceptable toxicity.
- Stratum 2 (average-risk group):
- Radiotherapy: Patients undergo craniospinal radiotherapy as in stratum 1, but at a
lower dose.
- High-dose chemotherapy and autologous SCT: Patients receive high-dose chemotherapy,
autologous SCT, G-CSF, and post-transplantation vincristine as in stratum 1.
Some patients undergo a neuropsychology assessment at baseline, before chemotherapy, and then
annually for 5 years.
After completion of study therapy, patients are followed every 3 months until month 30 (2.5
years) after diagnosis and then every 6 months until month 72 (6 years) after diagnosis.
