Proton Beam Radiation Therapy in Treating Young Patients Who Have Undergone Biopsy or Surgery for Medulloblastoma or Pineoblastoma

December 3, 2021 updated by: Nancy J. Tarbell, M.D., Massachusetts General Hospital

Phase II Study of Craniospinal and Posterior Fossa Irradiation Using Proton Beam Radiotherapy for Medulloblastoma and Pineoblastoma: Assessment of Acute and Long Term Sequelae

RATIONALE: Specialized radiation therapy that delivers radiation directly to the area where a tumor was surgically removed may kill any remaining tumor cells and cause less damage to normal tissue.

PURPOSE: This phase II trial is studying how well proton beam radiation therapy works in treating young patients who have undergone biopsy or surgery for medulloblastoma or pineoblastoma.

Detailed Description

OBJECTIVES:

  • Determine the 3-year incidence and severity of ototoxicity in young patients with medulloblastoma or pineoblastoma treated with adjuvant proton beam craniospinal and posterior fossa radiotherapy.
  • Determine the incidence of primary hypothyroidism and other endocrine dysfunction (neuroendocrine and end organ) in patients treated with this regimen.
  • Determine the incidence and severity of neurocognitive abnormalities in patients treated with this regimen.
  • Determine the acute side effects of this regimen, including esophagitis, upper and lower gastrointestinal tract disease, and weight loss, in these patients.
  • Determine the 3-year progression-free survival rate of patients treated with this regimen.

OUTLINE: Patients are stratified according to risk (standard vs high).

Patients receive proton beam craniospinal and posterior fossa radiotherapy once daily 5 days a week for 6-8 weeks*.

NOTE: *Unless otherwise specified by a co-existing protocol.

Patients undergo neurocognitive evaluation at baseline or within 3 months after completion of radiotherapy and then at 1, 3, and 5 years. Patients also undergo endocrine evaluation at baseline and then annually for 5 years; and audiology evaluation at baseline, before each course of cisplatin-based chemotherapy (if receiving this), and then annually for 5 years.

After completion of study treatment, patients are followed every 3-6 months for 2-5 years.

PROJECTED ACCRUAL: A total of 60 patients will be accrued for this study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Cumulative Incidence of Ototoxicity
Time Frame: 3 Years, 5 years, 7 years, 10 years
Percentage participants who experienced ototoxicity as measured by Common Toxicity Criteria for Adverse Events (CTCAE) v3.0 after the completion of radiation therapy in the overall participant population and by baseline measure subgroups. Incidence is shown after follow-up of 3 years, 5 years, 7 years, and 10 years.
3 Years, 5 years, 7 years, 10 years

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Cumulative Incidence of Endocrine Dysfunction (Neuroendocrine and End Organ Defects) at 3 Years
Time Frame: 3 years
Percentage of participants who experienced endocrine dysfunction (neuroendocrine and end organ defects) after 3 years of follow-up (as determined by CTCAE 3.0). Incidence is grouped by hormone type and risk group
3 years
Cumulative Incidence of Endocrine Dysfunction (Neuroendocrine and End Organ Defects) at 5 Years
Time Frame: 5 years
Percentage of participants who experienced endocrine dysfunction (neuroendocrine and end organ defects) after 5 years of follow-up (as determined by CTCAE 3.0). Incidence is shown by hormone type and risk group.
5 years
Cumulative Incidence of Endocrine Dysfunction (Neuroendocrine and End Organ Defects) at 7 Years
Time Frame: 7 years
Percentage of participants who experienced endocrine dysfunction (neuroendocrine and end organ defects) after 7 years of follow-up, as determined by CTCAE 3.0. Incidence is shown by hormone type and risk group

Cumulative Incidence of Endocrine Dysfunction (Neuroendocrine and End Organ Defects) at 7 Years
Time Frame: 3 years, 5 years, 7 years
percentage of participants who experienced endocrine dysfunction (neuroendocrine and end organ defects) as determined by CTCAE 3.0) at year 3, year 5, and year 7 of follow-up.

Mean Change Per-Year in Neurocognitive Outcomes
Time Frame: Baseline, 1, 3, 5, 7 years
The mean change per-year in neurocognitive outcomes as assessed by Wechsler Intelligence Scale for Children version 4 (WISC-IV). The test measures the Full Scale Intelligence Quotient (FSIQ) of children with the use of four indices; the Verbal Comprehension Index (VCI), Perceptual Reasoning Index (PRI), working memory test, and a processing speed test. FSIQ and the four indices are all assessed on a bell curve scale that has an average score of 100 and standard deviation of 15 points in the general population, meaning on average 68% of test takers would be within +/- 15 points of 100 and 95% within +/- 30 points. Higher scores represent higher intelligence and lower score represent reduced intelligence. Participants were assessed for changes in score with the use of repeated testing during a median follow-up time of 5.2 years. Repeated measures were taken at baseline, 1, 3, 5, and 7 years or until the participant was not available for evaluation (whichever comes first).
Baseline, 1, 3, 5, 7 years
Progression Free Survival
Time Frame: 5 years, 7 years, 10 years
The percentage of participants with progression free survival after five, seven, and ten years in the overall population and by risk and histological group.
5 years, 7 years, 10 years
Overall Survival
Time Frame: 5 years, 7 years, 10 years
the percentage of participants surviving after five and seven years and at the end of follow-up in the overall population. Survival is shown by risk and histological group.
5 years, 7 years, 10 years
