There are two types of external radiation treatments (proton beam and photon beam). As part of the participant's treatment, they will receive radiation to the entire central nervous system (CNS); this is known as craniospinal irradiation (CSI). In the past, photon radiation therapy has been used for CSI. In this study we will be examining the effects of proton beam radiation therapy. Studies have suggested that this kind of radiation can cause less damage to normal tissue than photon radiation therapy. The physical characteristics of proton beam radiation let the doctor safely deliver the amount of radiation delivered to the tumor that is normally delivered through standard therapy but spare more normal tissue in the process.

Further study details as provided by Massachusetts General Hospital:

Primary Outcome Measures:
  • Ototoxicity [ Time Frame: 3 years ]
    Incidence and severity of ototoxicity at three years following the completion of radiation therapy.

  • Endocrine dysfunction [ Time Frame: 3 years ]
    Incidence and severity of endocrine dysfunction at three years following completion of proton radiation therapy.

  • Neurocognitive Effects [ Time Frame: 3 years ]
    Incidence and severity of neurocognitive sequelae overall and in subgroups based on whether or not methotrexate was used as part of the treatment regimen

Secondary Outcome Measures:
  • Progression Free Survival [ Time Frame: 3 years ]
    3-year progression free survival rate of pediatric medulloblastoma and pineoblastoma patients treated with proton CSI treatment.

  • Treatment efficiency [ Time Frame: 2 years ]
    Speed of treating patients requiring cranial spinal irradiation and improve the safety of treating patients under anesthesia

  • Acute toxicity [ Time Frame: 2 years ]
    Frequency and severity of acute side effects from CSI using proton beam therapy, including nausea, esophagitis, and weight loss.

Enrollment: 90
Actual Study Start Date: April 2010
Estimated Study Completion Date: April 2024
Estimated Primary Completion Date: April 2018 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Proton Beam Radiation
Proton Beam Radiation
Radiation: proton beam radiation
Given once a day, 5 days a week (Monday-Friday)

Detailed Description:
  • Before beginning radiation therapy, participants will have scans done in order to prepare for the radiation treatment. Doctors will use information gathered from these scans to plan the best way to deliver radiation to the tumor.
  • The following procedures will be performed either before or during the radiotherapy: Hearing exam; neurocognitive exam; blood tests and cerebral spinal fluid test.
  • Not everyone who participates in this study will receive the same amount of proton radiation therapy. The length of time and amount of radiation received will depend upon the condition of the participant's disease. Radiation treatment will be given once a day, 5 days a week (Monday-Friday). The overall treatment course will be approximately 6 weeks.

Ages Eligible for Study:   3 Years to 25 Years   (Child, Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Participants must have undergone biopsy or attempted surgical resection and must have histologically confirmed medulloblastoma or pineoblastoma.
