Lead Sponsor
Children's Oncology Group
Brief Summary

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 radiation therapy with chemotherapy may kill more tumor cells.

PURPOSE: Phase II trial to study the effectiveness of etoposide plus radiation therapy followed by combination chemotherapy in treating children with newly diagnosed advanced medulloblastoma.

Detailed Description

OBJECTIVES:

* Assess the response rate and toxicity of oral etoposide and radiotherapy in children with newly diagnosed high stage medulloblastoma.

* Compare the response rate and toxicity of these patients to historical control patients registered on POG #9031.

* Estimate the 2-year event-free survival and overall survival of these patients.

* Evaluate the toxicity of dose intensive chemotherapy with oral etoposide, cisplatin, cyclophosphamide, and vincristine following craniospinal irradiation in these patients.

OUTLINE: Patients begin treatment within 1 month of surgery. Patients receive 6 weeks of radiotherapy to the head and spine, with boosts to the posterior fossa and to sites of metastasis. Patients also receive 2 courses of oral etoposide once daily for 3 weeks concurrent with and immediately following radiotherapy (weeks 1-3 and 5-7).

Patients then receive adjuvant chemotherapy consisting of cisplatin IV once every 4 weeks for 3 courses beginning on week 11, oral etoposide daily for 21 days every 4 weeks for 3 courses (weeks 11, 15, and 19), cyclophosphamide IV on days 1 and 2 with filgrastim (G-CSF) SQ daily for at least 10 days every 4 weeks for 8 courses (weeks 23-51), and vincristine IV on days 1, 8, and 15 every 4 weeks for 8 courses (weeks 23-51).

Patients are followed every 3 months for 1 year, every 4 months for 1 year, every 6 months for 1 year, and annually thereafter.

PROJECTED ACCRUAL: A total of 48 patients will be accrued for this study within about 2 years.

Primary Outcome Measures
NameTimeMethod
Assess the efficacy of oral etoposide at 50 mg/m2/day given concurrently with radiotherapy followed with dose intensive adjuvant chemotherapy in children with newly diagnosed high stage medulloblastomaEnd of course 1 (week 10)

It is possible that unacceptably high levels of toxicity may arise. For this reason, there is a 3-stage stopping rule designed to allow the Study Coordinator to stop this study early if it appears that the true proportion of eligible patients who suffer unacceptable levels of toxicity exceeds 10%.
