Focal Radiotherapy Plus Low Dose Craniospinal Irradiation Followed by Adjuvant Chemotherapy in WNT Subgroup Medulloblastoma.

Not applicable Interventional Tata Memorial Centre · NCT04474964

This study is testing a new way to treat children with a specific type of brain tumor by using lower doses of radiation to see if it can help them get better while causing fewer side effects.

What this trial studies

This clinical study focuses on treating children diagnosed with WNT pathway medulloblastoma, a type of brain tumor known for its favorable prognosis. The approach involves administering low dose craniospinal irradiation alongside focal radiotherapy, aiming to reduce long-term side effects associated with higher radiation doses while maintaining effective disease control. The study seeks to evaluate the safety and efficacy of this de-intensified treatment strategy in newly diagnosed patients. By carefully selecting participants based on specific eligibility criteria, the study aims to optimize treatment outcomes for this low-risk group.

Who should consider this trial

Good fit: Ideal candidates for this study are children aged 3 to 16 years with newly diagnosed WNT pathway medulloblastoma and minimal post-surgery residual disease.

Not a fit: Patients outside the age range of 3 to 16 years or those with other molecular subgroups of medulloblastoma may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce long-term toxicities in children treated for WNT medulloblastoma without compromising their survival rates.

How similar studies have performed: Other studies have explored de-intensification strategies in similar patient populations, showing promising results in reducing treatment-related toxicities.
