A Study Evaluating Limited Target Volume Boost Irradiation and Reduced Dose Craniospinal Radiotherapy 18.00 Gy and Chemotherapy In Children with Newly Diagnosed Standard Risk Medulloblastoma: A Phase III Double Randomized Trial.
COG # ACNS0331
This study wants to determine whether reducing the craniospinal dose of radiation therapy in children 3-7 years of age does not compromise event-free survival and overall survival as compared to treatment with a reduced dose of craniospinal radiation; and to determine if reducing the irradiated volume of the primary site tumor boost from the whole posterior fossa to the tumor bed only will not compromise event-free and overall survival.
- Patients must be greater than or equal to three years and less than 22 years at the time of diagnosis.
- The presence of a posterior fossa medulloblastoma as determined by institutional pathologic evaluation.
- Preoperative and postoperative cranial MRI with and without contrast must be available.
- Patients must have adequate organ function as defined by the protocol.
