  Purpose

RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. Drugs used in chemotherapy, such as vincristine, cisplatin, lomustine, and cyclophosphamide, work in different ways to stop tumor cells from dividing so they stop growing or die. Giving radiation therapy with chemotherapy after surgery may kill any remaining tumor cells. It is not yet known whether standard-dose radiation therapy combined with chemotherapy after surgery is more effective than reduced-dose craniospinal (head and spine) radiation therapy plus either posterior fossa (back of the brain) boost or tumor bed (site of the tumor) boost radiation therapy combined with chemotherapy in treating medulloblastoma.

PURPOSE: This randomized phase III trial is studying standard-dose radiation therapy to see how well it works compared to reduced-dose craniospinal radiation therapy AND posterior fossa boost radiation therapy to see how well it works compared to tumor bed boost radiation therapy when given together with chemotherapy in treating young patients who have undergone surgery for newly diagnosed standard-risk medulloblastoma.

Primary Outcome Measures:
  • Time to event as measured by the time to disease progression, disease recurrence, death from any cause, or occurrence of a second malignant neoplasm at 3 years [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Time to recurrence, progression, or death due to cancer at 3 years [ Designated as safety issue: No ]
  • Time to death at 3 years [ Designated as safety issue: No ]
  • Local Posterior Fossa (LPF) Failure as determined by tumor recurrence or progression within the tumor bed at 3 years [ Designated as safety issue: No ]
  • Non-local Posterior Fossa (NLPF) Failure as determined by recurrence outside CTVboost but within CTVPF at 3 years [ Designated as safety issue: No ]
  • Non-Posterior Fossa (NPF) Failure as determine by recurrence within the neuroaxis but outside of CTVPF at 3 years [ Designated as safety issue: No ]
  • Post-treatment neurocognitive function as measured by Neuropsychometric battery at 3 years [ Designated as safety issue: No ]
  • Post-treatment hearing loss as measure by Audiogram or brainstem auditory evoked response (BAER) at 3 years [ Designated as safety issue: No ]
  • Post-treatment endocrine function (e.g., growth, sexual maturation, and need for hormone replacement) by laboratory assesment, clinical history, and exam at 3 years [ Designated as safety issue: No ]
  • Quality of Life as measured by Pediatric Quality of Life Inventory (PedsQL), Behavior Assessment System for Children (BASC), Behavior Rating Inventory of Executive Function (BRIEF), and Adaptive Behavior Assessment System (ABAS) at 3 years [ Designated as safety issue: No ]
