Risk-Adapted Therapy for Young Children With Embryonal Brain Tumors, Choroid Plexus Carcinoma, High Grade Glioma or Ependymoma
Not Recruiting
Trial ID: NCT00602667,7,29,45,152,17535,26500,50650,50652,45600
Purpose
RATIONALE: In this study a combination of anti-cancer drugs (chemotherapy) is used to treat
brain tumors in young children. Using chemotherapy gives the brain more time to develop
before radiation is given. The chemotherapy in this study includes the drug methotrexate.
This drug was an important part of the two clinical trials which resulted in the best
survival results for children less than 3 years of age with medulloblastoma. Most patients
treated on this trial will also receive radiation which is carefully targeted to the area of
the tumor. This type of radiation (focal conformal or proton beam radiotherapy) may result in
fewer problems with thinking and learning than radiation to the whole brain and spinal cord.
PURPOSE: This clinical trial is studying how well giving combination chemotherapy together
with radiation therapy works in treating young patients with newly diagnosed central nervous
system tumors.

Eligibility
Histologically confirmed newly diagnosed CNS tumors of any of the following :
- Medulloblastoma (all histologic subtypes, including medullomyoblastoma and melanotic
medulloblastoma)
- Supratentorial primitive neuroectodermal tumor (PNET) (including CNS neuroblastoma or
ganglioneuroblastoma, medulloepithelioma, and ependymoblastoma)
- Pineoblastoma
- Atypical teratoid rhabdoid tumor (ATRT)
- Choroid plexus carcinoma
- High grade glioma (including anaplastic astrocytoma, anaplastic oligodendroglioma,
anaplastic ganglioglioma, pleomorphic xanthoastrocytoma with anaplastic features,
high-grade astroblastoma , anaplastic pilocytic astrocytoma, malignant glioneuronal
tumor, glioblastoma multiforme), or gliosarcoma,
- Ependymoma (including all ependymoma histological variants)
- Age < 3 years at time of diagnosis for all histological diagnosis. Medulloblastoma
patients ≥ 3 and < 5years old at diagnosis who have non-metastatic disease with no
more than 1cm2 of residual tumor are also eligible.
- Meets criteria for 1 of the following risk groups:
- Low-risk group:
- Histologically confirmed nodular desmoplastic medulloblastoma, including
medulloblastoma with extensive nodularity
- Focal areas of anaplasia or other atypical features suggesting more
aggressive phenotype in a tumor otherwise considered nodular desmoplastic
should be treated on the intermediate-risk group, with final risk
stratification at the discretion of principal investigator and study
pathologist
- No evidence of CNS metastasis 7 to 28 days after surgery by MRI and cytologic
examination of lumbar cerebrospinal fluid (CSF)
- Ventricular CSF from a shunt or Ommaya reservoir may be used to rule out M1
disease when lumbar puncture is medically contraindicated
- Intermediate-risk group assignment when there is no other evidence of
metastasis and CSF sampling is not possible
- Gross total resection, defined as residual tumor or imaging abnormality (not
definitive for residual tumor) with a size of < 1 cm2 confirmed on postoperative
CT scan or MRI
- Brain stem invasion by the tumor in the absence of imaging evidence of residual
tumor (tumor size < 1 cm2) and otherwise meets criteria for the low-risk group,
the patient will be classified as low-risk
- Desmoplastic medulloblastoma patients who are ≥3 -<5 years of age will NOT be
eligible for the low risk arm of the protocol.
- Intermediate-risk group:
- Histologically confirmed nodular desmoplastic medulloblastoma with less than
gross total resection and no evidence of metastasis
- Any eligible histologic diagnosis other than desmoplastic medulloblastoma with no
evidence of CNS metastasis
- Medulloblastoma patients who are ≥3 and < 5 yrs of age irrespective of histology
and with no evidence of CNS metastasis
- High-risk group:
- Any eligible histologic diagnosis with evidence of CNS metastasis
- Patients with extraneural metastasis are eligible for treatment on the high-risk
group
PATIENT CHARACTERISTICS:
- Lansky performance status ≥ 30 (except for posterior fossa syndrome)
- WBC > 2,000/mm3
- Platelets > 50,000/mm3 (without support)
- Hemoglobin > 8 g/dL (with or without support)
- ANC > 500/mm3
- Serum creatinine < 3 times upper limit of normal (ULN)
- ALT < 5 times ULN
- Total bilirubin < 3 times ULN
PRIOR CONCURRENT THERAPY:
- See Disease Characteristics
- No more than 31 days since prior definitive surgery
- No prior radiotherapy or chemotherapy other than corticosteroid therapy
Intervention(s):
