Outcomes of Proton vs. Photon Therapy for IDH Mutated Gliomas

Short Term Outcomes After PRoton and PhotoN RadiOtherapy for IDH Mutated Grade 2 and 3 Gliomas

Observational Erasmus Medical Center · NCT06180434

This study tests whether proton therapy works better and is safer than photon therapy for people with certain types of brain tumors called IDH mutated gliomas.

What this trial studies

This study investigates the short-term outcomes of patients with grade 2 and 3 IDH mutated gliomas treated with proton therapy compared to those treated with photon therapy. It involves a retrospective analysis of data collected from multiple medical centers in the Netherlands, focusing on interventions, survival rates, and toxicity following treatment. The aim is to determine if proton therapy offers any advantages in terms of disease progression and safety compared to traditional photon therapy.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with histopathologically confirmed grade 2 or 3 IDH mutated gliomas who received radiotherapy between January 1, 2018, and June 30, 2022.

Not a fit: Patients who have received prior cranial radiotherapy or those who have contraindications for MRI imaging may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into the effectiveness and safety of proton therapy, potentially leading to improved treatment options for glioma patients.

How similar studies have performed: While this study explores a relatively novel approach, previous studies have indicated potential benefits of proton therapy in reducing radiation exposure to healthy tissue, though direct comparisons with photon therapy in this specific context are limited.
