COMPASSIONATE ALLOWANCE INFORMATION

GLIOMA – GRADE III and IV

ALTERNATE NAMES

High Grade Malignant Glioma; Malignant Glioma Grade III; Malignant Glioma Grade IV; Glioblastoma; Anaplastic Astrocytoma; Undifferentiated Glioma; Anaplastic Glioma

DESCRIPTION

Glioma is a broad category of brain and spinal cord tumors that come from glial cells, the main brain cells that can develop into cancer. Approximately 80 percent of malignant brain tumors are gliomas. These gliomas are categorized as ependymomas, astrocytomas or oligodendrogliomas. The exact cause of malignant gliomas is unknown.

DIAGNOSTIC TESTING, PHYSICAL FINDINGS, AND ICD-9-CM CODING

Diagnostic testing: Malignant gliomas are diagnosed by a CT scan, MRI scan and biopsy. MRI is the preferred diagnostic tool.

ICD9: 191.0-9

ONSET AND PROGRESSION

Malignant gliomas can develop at any age. They tend to grow and become more malignant over time. The peak incidence generally occurs in the fifth and sixth decade of life. Prognosis is often poor for individuals with grades III and IV tumors with the average survival time approximately 12 months. Few individuals survive beyond three years with conventional treatment.

TREATMENT

Treatment depends on the location of the tumor and its progression. These tumors tend to grow or infiltrate into the normal brain tissue. Standard treatment is surgery followed by radiation therapy. If surgery is not an option, radiation therapy is given. Chemotherapy is sometimes given during or after radiation therapy.

SUGGESTED PROGRAMMATIC ASSESSMENT*

Suggested MER for evaluation:
