Poly-ICLC in Treating Patients With Recurrent or Progressive Anaplastic Glioma

DISEASE CHARACTERISTICS:

• Histologically confirmed intracranial anaplastic glioma, including any of the following subtypes:

  • Anaplastic astrocytoma
  • Anaplastic oligodendroglioma
  • Anaplastic mixed oligoastrocytoma
  • Other anaplastic gliomas NOTE: Patients with an original histology of low-grade glioma are allowed provided a subsequent histological diagnosis of an anaplastic glioma is made
• Must have evidence of tumor recurrence or progression by MRI or CT scan* NOTE: *Steroid dose must be stable for at least 5 days before scan

• Prior radiotherapy required

  • Patients who have had prior interstitial brachytherapy or stereotactic radiosurgery must have confirmation of true progressive disease rather than radiation necrosis by positron-emission tomography, thallium scanning, magnetic resonance spectroscopy, or surgical documentation of disease

• Relapsed disease

  • Progression after initial therapy (e.g., radiotherapy with or without chemotherapy)
  • No more than 3 prior therapies (initial therapy and treatment for no more than 2 prior relapses)
  • Surgical resection for relapsed disease with no anticancer therapy for up to 12 weeks followed by another surgical resection is considered 1 relapse
  • For patients who have had prior therapy for a low-grade glioma, the surgical diagnosis of high-grade glioma is considered the first relapse
• Must be registered in the North American Brain Tumor Consortium Data Management Center database
