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.

To quantify the decay in signal, 134 scans from 53 patients were analyzed by recording the mean activation value (MAV), the average recorded PET signal from activation, within the target volume. With each patient being given the same dose, the percent standard deviation in the MAV can serve as a quantitative representation of signal loss due to radioactive decay.

- detailed Description
- All patients with medulloblastoma who were diagnosed prior to their 3rd birthday will contribute to both the biology and therapeutic primary objectives of this protocol. Furthermore patients who were ≥3 and \<5 years old at the time of diagnosis will also be included in the cohort for these primary objectives as long as they meet the eligibility criteria as outlined in Amendment 8.0 of this protocol. Patients in the 3-5 year old age cohort who enrolled on previous versions of this protocol and who do not meet the criteria as outlined in Amendment 8.0 of this protocol will be excluded from the outcome analyses of the biology and therapeutic primary objectives of the protocol. OBJECTIVES: Primary * To identify patterns of methylation profiling that are associated with progression-free survival among young pediatric patients with medulloblastoma treated with risk-adapted therapy. * To estimate the event-free survival distribution of young medulloblastoma patients treated with risk-adapted therapy. Secondary * To perform high-resolution genome-wide analyses of chromosomal abnormalities and gene expression patterns, and evaluate the relationship of these to other clinicopathological variables. * To evaluate specific tumor types for molecular abnormalities with suspected prognostic or therapeutic significance. * To evaluate the feasibility of collecting frozen and fixed tumor samples for analysis using high-resolution molecular biology tools. * To estimate the event-free and overall survival of patients treated with the proposed risk-adapted therapy regimen, and to descriptively compare these survival rates to historical controls. * To estimate the rates of local and distant disease progression in patients treated with focal radiotherapy (RT) to the post-operative tumor bed using a 5 mm clinical target volume margin. * To estimate the objective response rate (sustained for 8 weeks) to induction chemotherapy including high-dose intravenous methotrexate for patients with residual or metastatic disease. * To evaluate the feasibility and toxicity of administering low-dose intravenous vinblastine in conjunction with induction chemotherapy to patients with metastatic disease. * To evaluate the feasibility and toxicity of administering consolidation therapy including cyclophosphamide and pharmacokinetically targeted topotecan to patients with metastatic disease, and to estimate the sustained (for 8 weeks) objective response rate (complete response and partial response) to such therapy in patients with measurable residual disease after induction. * To evaluate the feasibility and toxicity of administering oral maintenance therapy in young children. * To use quantitative magnetic resonance (MR) measures (volumetric, diffusion, and perfusion) of young brain tumor patients receiving chemotherapy including high-dose intravenous methotrexate to assess impact of treatment on developing brain. * To investigate the feasibility of using PET as an in-vivo dosimetric and distal edge verification system for patients treated with proton beam therapy (for participants enrolled at St Jude only). OUTLINE: This is a multicenter study. Patients are stratified according to disease risk (low-risk vs intermediate-risk vs high-risk). Therapy consists of risk adapted induction, consolidation and maintenance chemotherapy. Focal irradiation is given to intermediate risk patients who have reached at least 12 months of age upon completion of induction. Intermediate risk patients who have not will receive low risk chemotherapy to delay RT until the age of 12 months. Patients may consent to provide tumor tissue and blood samples for biological studies. Tumor tissues are analyzed for the activation of the wnt signaling pathway (β-catenin), activation of the shh signaling pathway (Gli-1/SFRP1), and ERBB2; validation of novel patterns of gene expression via immunohistochemical (IHC) analysis; loss of chromosomes 6, 8p, 9q22, isochromosome 17q; amplification of MYCC, MYCN, and MYCL; validation of genetic abnormalities via interphase fluorescence in situ hybridization (iFISH); construction of gene expression profiles via microarray analysis; single nucleotide polymorphism (SNP) analysis for DNA purity and integrity using UV spectrophotometry and agarose gel electrophoresis; amplification of DNA via PCR and a combination of previously published and 'in-house' generated primers; potential oncogenes and tumor suppressor genes via DNA sequence analysis; expression of a number of cell signal proteins implicated in the biology of medulloblastoma via western blot; expression of additional proteins encoded by genes associated through SNP and gene expression array analysis with clinical disease behavior; and differential expression pattern of genes detected using microarray analysis via RT-PCR. DNA extraction and construction of tissue microarrays (TMAs) from tumor tissue will also be used for future IHC and FISH analysis. Blood samples are analyzed for constitutional DNA from patients whose tumors contain gene mutations via sequence analysis of constitutional DNA; cyclophosphamide and its metabolites via liquid chromatography mass spectroscopy method; topotecan lactone via isocratic high-performance liquid chromatography assay with fluorescence detection; and alpha-1-acid glycoprotein (AAGP) concentrations via immunoturbidimetric assay. After completion of study treatment, patients are followed every 6 months for 5 years.
