What is the purpose of this trial?

This randomized phase III trial is studying how well standard-dose radiation therapy works compared to reduced-dose radiation therapy in children 3-7 years of age AND how well standard volume boost radiation therapy works compared to smaller volume boost radiation therapy when given together with chemotherapy in treating young patients who have undergone surgery for newly diagnosed standard-risk medulloblastoma. Radiation therapy uses high-energy x-rays to damage tumor cells. Drugs used in chemotherapy, such as vincristine, cisplatin, lomustine, and cyclophosphamide, work in different ways to stop tumor cells from dividing so they stop growing or die. Giving radiation therapy with chemotherapy after surgery may kill any remaining tumor cells. It is not yet known whether standard-dose radiation therapy is more effective than reduced-dose radiation therapy when given together with chemotherapy after surgery in treating young patients with medulloblastoma.

Are You a Good Fit for This Trial?

This trial is for young patients aged 3-7 with newly diagnosed standard-risk medulloblastoma, a type of brain tumor. They should have had surgery but no prior chemotherapy or radiotherapy, and their cancer shouldn't have spread. Their blood counts and organ functions need to meet specific criteria, they can't be pregnant or nursing, and must use effective contraception if applicable.

Inclusion Criteria

Fertile patients must use effective contraception

Platelet count > 100,000/uL (transfusion independent)

Hemoglobin > 10 g/dL (transfusions allowed)

6 weeks

Daily visits (in-person) for radiation therapy

Chemotherapy

Patients receive vincristine intravenously on specified days during radiation therapy

6 weeks

Weekly visits (in-person) for chemotherapy administration

Maintenance Chemotherapy

Patients receive maintenance chemotherapy with two different regimens for a total of 9 courses

54 weeks

Follow-up

Participants are monitored for safety and effectiveness after treatment

3 years

Every 3 months for 1 year, every 6 months for 2 years, then annually

What Are the Treatments Tested in This Trial?

Interventions

• Cisplatin
• Craniospinal Irradiation
• Cyclophosphamide
• Involved-Field Radiation Therapy
• Lomustine
• Radiation Therapy
• Vincristine Sulfate

Trial Overview The study compares different radiation therapy doses and volumes when combined with chemotherapy drugs like vincristine sulfate, lomustine, cisplatin, and cyclophosphamide after surgery in these children. It aims to find out which radiation strategy works best at killing remaining tumor cells without causing unnecessary harm.
