RATIONALE: Specialized radiation therapy that delivers radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue.

PURPOSE: This phase II trial is studying how well radiation therapy works in treating young patients with gliomas.

Primary Outcome Measures:
  • Marginal-failure Rate [ Time Frame: Up to 5 years ]
    Patients who do not recur as well as those with either central or distant recurrence would be treatment successes for this endpoint. Monitoring will be based on a Bayesian rule, with binomial likelihood and a Beta on the parameter p, the proportion of failures that are marginal failures.

Secondary Outcome Measures:
  • Progression-free Survival Probability [ Time Frame: 3 years ]
    To estimate the progression-free survival rate for patients with recurrent, progressive or symptomatic low-grade gliomas after treatment with reduced field conformal radiation.

  • Event-free Survival Probability [ Time Frame: 3 years ]
    To estimate the event-free survival rate for patients with recurrent, progressive or symptomatic low-grade gliomas after treatment with reduced field conformal radiation

  • Overall Survival Probability [ Time Frame: 3 years ]
    To estimate the overall survival rate for patients with recurrent, progressive or symptomatic low-grade gliomas after treatment with reduced field conformal radiation.

  • Quality of Life (QOL) [ Time Frame: Up to 5 years ]
    QOL accessed using the Behavior Assessment System for Children (BASC), the Adaptive Behavior Assessment System (ABAS), the Behavior Rating Inventory of Executive Function (BRIEF), and the Symptom Checklist-90-R (SCL-90-R).

  • MIB-1 Labeling Index Using Immunohistochemical Techniques With the MIB-1 Antibody According to Established Methods [ Time Frame: At baseline ]
    The MIB-1 labeling Index will be calculated as the percentage of tumor nuclei that are immunoreactive.

  • Correlation MIB-1 Labeling Index With PFS [ Time Frame: Up to 10 years ]
    The primary methods of analysis will be via stratified Cox regression

  • IMRT

Detailed Description:



  • Determine the marginal-failure rate in young patients with low-grade gliomas treated with reduced-field conformal radiotherapy.


  • Determine the progression-free survival, event-free survival, and overall survival rates of young patients treated with this regimen.
  • Determine quality of life of patients treated with this regimen.
  • Correlate MIB-1 labeling index with progression-free survival and overall survival of these patients.

OUTLINE: This is a multicenter study.

Patients undergo reduced-field conformal radiotherapy 5 days a week for 6 weeks in the absence of disease progression or unacceptable toxicity.

Quality of life is assessed at baseline or 6 weeks after completion of study treatment and then at 2 and 5 years (closed as of 10/27/2010).

After completion of study treatment, patients are followed every 3 months for 2 years, every 6 months for 2 years, and then annually thereafter.
