Description
Summary
This phase II trial studies how well reduced doses of radiation therapy to the brain and spine (craniospinal) and chemotherapy work in treating patients with newly diagnosed type of brain tumor called WNT)/Wingless (WNT)-driven medulloblastoma. Recent studies using chemotherapy and radiation therapy have been shown to be effective in treating patients with WNT-driven medulloblastoma. However, there is a concern about the late side effects of treatment, such as learning difficulties, lower amounts of hormones, or other problems in performing daily activities. Radiotherapy uses high-energy radiation from x-rays to kill cancer cells and shrink tumors. Drugs used in chemotherapy, such as cisplatin, vincristine sulfate, cyclophosphamide and lomustine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving reduced craniospinal radiation therapy and chemotherapy may kill tumor cells and may also reduce the late side effects of treatment.

A Phase 2 Study of Reduced Therapy for Newly Diagnosed Average-Risk WNT-Driven Medulloblastoma Patients
Details
PRIMARY OBJECTIVE:
- To estimate the progression-free survival (PFS) of children >= 3 years of age with wingless-type MMTV integration site family (WNT)-driven average-risk medulloblastoma using reduced craniospinal radiotherapy (CSI) (18 Gray [Gy]) with a limited target volume boost to the tumor bed of 36 Gy for a total of 54 Gy and reduced chemotherapy approach (no vincristine [vincristine sulfate] during radiotherapy and reduced-dose maintenance chemotherapy) and to monitor the PFS for early evidence that the outcome is unacceptable.
SECONDARY OBJECTIVES:
- To prospectively test the hypothesis that deoxyribonucleic acid (DNA) methylation profiling will accurately classify WNT-driven medulloblastoma.
II. To prospectively evaluate and longitudinally model the cognitive, social, emotional, behavioral, and quality of life (QoL) functioning of children who are treated with reduced CSI (18 Gy) with a limited target volume boost to the tumor bed (to a total of 54 Gy) and reduced chemotherapy (reduced cisplatin, vincristine, and lomustine [CCNU]).
EXPLORATORY OBJECTIVES:
- To explore whether DNA methylation profiling of medulloblastoma samples will result in a predictive classification scheme for the Sonic Hedgehog (SHH), Group 3, and Group 4 medulloblastoma subgroups according to the Heidelberg classifier. This will be addressed in a separate biology protocol.
II. To describe the audiologic and endocrinologic toxicities, as well as peripheral neuropathy, in children treated with reduced CSI (18 Gy) with a limited target volume boost to the tumor bed (to a total of 54 Gy) and reduced cisplatin and vincristine chemotherapy.
OUTLINE:
RADIATION THERAPY: Beginning 4-5 weeks after surgery, patients undergo craniospinal radiation therapy 5 days a week for 6 weeks.
MAINTENANCE THERAPY (WEEKS 1, 3, 5, and 7): Beginning 4-6 weeks after completion of radiation therapy patients receive lomustine orally (PO) on day 1, vincristine sulfate intravenously (IV) via minibag on days 1, 8, and 15, and cisplatin IV over 6 hours on day 1. Treatment repeats every 42 days in the absence of disease progression or unacceptable toxicity.
MAINTENANCE THERAPY (WEEKS 2, 4, AND 6): Patients receive cyclophosphamide IV over 30-60 minutes on days 1 and 2, mesna IV over 15-30 minutes on days 1 and 2, and vincristine sulfate IV via minibag on days 1 and 8. Treatment repeats every 28 days in the absence of disease progression or unacceptable toxicity.
Patients also undergo magnetic resonance imaging (MRI) throughout the trial.
After completion of study treatment, patients are followed up every 3 months for 2 years, every 6 months for 2 years, and then annually for 6 years.

Eligibility
You can join if…
Open to people ages 3-21
- Patients must be greater than or equal to 3 years and less than 22 years of age at the time of enrollment
- Patients must be newly diagnosed and have:
- Eligibility confirmed by rapid central pathology and molecular screening review on APEC14B1:
- Classical histologic type (non LC/A) WNT medulloblastoma
- Positive nuclear beta-catenin by immunohistochemistry (IHC)
- Positive for CTNNB1 mutation by Sanger sequencing
- Negative for MYC and MYCN by fluorescence in situ hybridization (FISH)
- Eligibility confirmed by rapid central pathology and molecular screening review on APEC14B1:
- Patient must have negative lumbar cerebrospinal fluid (CSF) cytology
- Note: CSF cytology for staging should be performed no sooner than 14 days post operatively to avoid false positive CSF; ideally, CSF should be obtained between day 14 and day 21 to allow for final staging status before enrollment onto the study; patients with positive CSF cytology obtained 0 to 14 days after surgery should have cytology repeated to determine eligibility and final CSF status; patients with negative CSF cytology from lumbar puncture obtained 0 to 14 days after surgery do not need cytology repeated; patients with negative CSF cytology from lumbar puncture obtained prior to surgery do not need cytology repeated post-operatively
- Patients must have eligibility confirmed by Rapid Central Imaging Review on APEC14B1; patients must have =< 1.5 cm2 maximal cross-sectional area of residual tumor; whole brain magnetic resonance imaging (MRI) with and without gadolinium and spine MRI with gadolinium must be performed
- Patients must be enrolled, and protocol therapy must be projected to begin, no later than 36 days after definitive diagnostic surgery (day 0)
- Peripheral absolute neutrophil count (ANC) >= 1000/uL
- Platelet count >= 100,000/uL (transfusion independent)
- Hemoglobin >= 8.0 g/dL (may receive red blood cell [RBC] transfusions)
Creatinine clearance or radioisotope glomerular filtration rate (GFR) >= 70 mL/min/1.73 m2 or a serum creatinine based on age/gender as follows:
- 3 to < 6 years of age: maximum (max) serum creatinine 0.8 mg/dL (males and females)
- 6 to < 10 years of age: max serum creatinine 1 mg/dL (males and females)
