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. 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.


Study summary:

PRIMARY OBJECTIVES: I. To determine if the proposed treatment for children >= 8.0 months and < 3 years of age at registration with non-metastatic (M0) medulloblastoma is more effective than the combined treatments given to children of the same age and extent of disease on POG 9233, as measured by event-free survival (EFS) rates. SECONDARY OBJECTIVES: I. To assess the feasibility and safety of the planned use of second look surgery and focal conformal radiation therapy following chemotherapy. II. To determine the acute and chronic toxicities associated with the above treatment regimens. III. To describe the neuropsychological and neuroendocrine effects of this systemic chemotherapy, surgery, and local, conformal radiation. IV. To determine the feasibility and validity of a centralized telephone interview based data collection method for neuropsychological evaluations. V. To determine the incidence of atypical teratoid/rhabdoid tumor (AT/RT) in children enrolled on this study. 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.
