Trial Summary

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications. However, it mentions that patients with seizure disorders can participate if their condition is well controlled with anticonvulsants. It's best to discuss your specific medications with the trial team.

What data supports the effectiveness of the treatment for medulloblastoma?

Research shows that chemotherapy, including drugs like vincristine and cisplatin, is increasingly effective for treating medulloblastoma, especially when combined with radiation therapy. Studies suggest that adding chemotherapy to reduced-dose radiotherapy may improve survival rates and reduce the need for higher doses of radiation.12345

Is the treatment of reduced radiation and chemotherapy for medulloblastoma generally safe in humans?

The treatment involving reduced radiation and chemotherapy for medulloblastoma has shown some safety concerns, including short-term toxicity and potential hearing loss (ototoxicity) due to radiation and certain chemotherapy drugs like cisplatin. However, substituting cisplatin with carboplatin may reduce the risk of hearing loss, although other side effects like hematologic toxicity (blood-related side effects) can still occur.36789

How does the treatment of reduced radiation and chemotherapy for medulloblastoma differ from other treatments?

This treatment is unique because it combines reduced-dose radiation with chemotherapy to potentially improve survival rates while minimizing the harmful side effects of full-dose radiation, especially in children. The approach aims to balance effective cancer treatment with reducing long-term damage, which is particularly important for young patients.3451011

What is the purpose of this trial?

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.

Experimental Treatment
Group I: Treatment (reduced radiation therapy and chemotherapy)Experimental Treatment8 Interventions
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 PO on day 1, vincristine sulfate IV over 1 minute or 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 over 1 minute or via minibag on days 1 and 8. Treatment repeats every 28 days in the absence of disease progression or unacceptable toxicity. Patients also undergo MRI throughout the trial.

Findings from Research

In a study of 17 children with high-risk medulloblastoma, the treatment combining weekly vincristine during radiation and adjuvant carboplatin and vincristine resulted in a 3-year overall survival rate of 70.6% and a progression-free survival (PFS) rate of 58.8%.
The treatment was generally well tolerated, with only 17.6% of patients experiencing severe neutropenia during radiation, although complications increased during adjuvant chemotherapy, indicating that while the approach is effective, patients with metastatic disease may need more aggressive treatment.

In a study of 24 medulloblastoma patients treated with carboplatin instead of cisplatin, 23 patients were alive at the time of assessment, indicating a favorable overall survival rate.
Only 10.5% of patients experienced significant hearing loss, suggesting that carboplatin has a lower risk of ototoxicity compared to traditional cisplatin treatments, especially in younger patients.

In a study of 26 pediatric patients with high-risk medulloblastoma, a treatment regimen of carboplatin, etoposide, and radiotherapy resulted in a 69% global survival rate and a 64% disease-free survival rate after 60 months.
The treatment was found to be safe, with no significant renal or auditory toxicity, and any hematological toxicity experienced was temporary and reversible.
