RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage tumor cells. Combining more than one drug and combining chemotherapy with radiation therapy may kill more tumor cells.
- Determine the complete and partial response rate of patients with adult medulloblastoma, primitive neuroectodermal tumor, or disseminated ependymoma treated with preradiation combination chemotherapy.
- Determine the progression free survival and overall survival of these adult patients treated with combination chemotherapy followed by craniospinal radiation.
- Determine the toxic effects associated with this treatment in these patients.
OUTLINE: Patients receive cisplatin IV over 6 hours, etoposide IV, and vincristine IV over 1-2 minutes on day 1; etoposide IV and cyclophosphamide IV over 1-2 hours on days 2-3; filgrastim (G-CSF) subcutaneously (SC) on days 4-13; and vincristine IV over 1-2 minutes on day 15. Treatment repeats every 42 days for up to 3 courses in the absence of disease progression or unacceptable toxicity.
Within 4-6 weeks after the last chemotherapy course, patients undergo radiotherapy 5 days a week for 6 to 7 weeks.
Patients are followed every 3 months for 2 years, every 6 months for 3 years, and then annually for 5-10 years.
PROJECTED ACCRUAL: A total of 33 patients will be accrued for this study within 3 years.
Primary Purpose: Treatment
Brain and Central Nervous System Tumors

Drug therapy given to augment or stimulate some other form of treatment such as surgery or radiation therapy. Adjuvant chemotherapy is commonly used in the therapy of cancer and can be administered before or after the primary treatment.
A semisynthetic derivative of PODOPHYLLOTOXIN that exhibits antitumor activity. Etoposide inhibits DNA synthesis by forming a complex with topoisomerase II and DNA. This complex induces breaks in double stranded DNA and prevents repair by topoisomerase II binding. Accumulated breaks in DNA prevent entry into the mitotic phase of cell division, and lead to cell death. Etoposide acts primarily in the G2 and S phases of the cell cycle.
Radiotherapy given to augment some other form of treatment such as surgery or chemotherapy. Adjuvant radiotherapy is commonly used in the therapy of cancer and can be administered before or after the primary treatment.
Derivatives of chondroitin which have a sulfate moiety esterified to the galactosamine moiety of chondroitin. Chondroitin sulfate A, or chondroitin 4-sulfate, and chondroitin sulfate C, or chondroitin 6-sulfate, have the sulfate esterified in the 4- and 6-positions, respectively. Chondroitin sulfate B (beta heparin; DERMATAN SULFATE) is a misnomer and this compound is not a true chondroitin sulfate.
An inorganic and water-soluble platinum complex. After undergoing hydrolysis, it reacts with DNA to produce both intra and interstrand crosslinks. These crosslinks appear to impair replication and transcription of DNA. The cytotoxicity of cisplatin correlates with cellular arrest in the G2 phase of the cell cycle.
