Combination Chemotherapy Followed by Second-Look Surgery and Radiation Therapy in Treating Children With Nonmetastatic Medulloblastoma or Primitive Neuroectodermal Tumor - Full Text View

Sponsor:	Children's Oncology Group
Collaborator:	National Cancer Institute (NCI)
Information provided by:	National Cancer Institute (NCI)
ClinicalTrials.gov Identifier:	NCT00006461

Purpose

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 surgery and radiation therapy may kill more tumor cells.

PURPOSE: This phase III trial is studying how well combination chemotherapy followed by second-look surgery and radiation therapy works in treating children with nonmetastatic medulloblastoma or primitive neuroectodermal tumor.

Detailed Description:

OBJECTIVES:

Compare the efficacy of cyclophosphamide, vincristine, cisplatin, and etoposide followed by second-look surgery and focal conformal radiotherapy vs combination therapy administered on POG 9233 in terms of event-free survival rates in children with nonmetastatic medulloblastoma or posterior fossa primitive neuroectodermal tumor.
Assess the feasibility and safety of this treatment regimen in these patients.
Determine the acute and chronic toxicities of this regimen in these patients.
Determine the neuropsychological and neuroendocrine effects of this regimen in these patients.
Determine the incidence of atypical teratoid/rhabdoid tumor in these patients.

OUTLINE: This is a multicenter study.

Patients receive induction chemotherapy consisting of vincristine IV on days 1, 8, and 15; cisplatin IV over 6 hours on day 1; cyclophosphamide IV over 30 minutes on day 2; and oral etoposide daily on days 2-22. Treatment repeats every 28 days for a total of 4 courses.

After completion of induction chemotherapy, patients with residual disease undergo a second resection.

Within 4 weeks after completion of induction chemotherapy or second resection, patients receive focal conformal radiotherapy daily, 5 days a week, for 6 weeks.

Four weeks after completion of radiotherapy, patients receive alternating treatments of maintenance chemotherapy. Patients receive vincristine IV on days 1, 8, and 15 and cyclophosphamide IV over 30 minutes on day 1 of courses 1, 3, 5, and 7 and oral etoposide daily on days 1-21 of courses 2, 4, 6, and 8. Treatment continues every 28 days for 8 courses.

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

PROJECTED ACCRUAL: A total of 65 patients will be accrued for this study.
