Impact of Hippocampal Avoidance During Whole Brain Radiotherapy on Cognitive Function

Official title: A Prospective Study of the Impact of Hippocampal Avoidance During Whole Brain Radiotherapy on Neurocognitive Function Decline

Run by Chang Gung Memorial Hospital · NCT02504788 · Data updated 2026-11-12

This study is testing whether a special type of brain radiation that avoids the hippocampus can help people with brain tumors keep their thinking skills better than regular radiation.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are patients with non-hematopoietic malignancies and limited brain metastases who are referred for WBRT.

Probably not a fit

Patients with metastases located near the hippocampus or those with a history of prior brain radiotherapy may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study investigates the effects of hippocampal-sparing whole brain radiotherapy (WBRT) on neurocognitive function decline in patients with brain metastases. It aims to determine whether avoiding radiation exposure to the hippocampus can mitigate cognitive decline associated with WBRT. Patients with confirmed non-hematopoietic malignancies and limited brain metastases will be treated with this specialized radiotherapy approach. The study will assess cognitive outcomes compared to traditional WBRT methods.

Why it matters

Potential benefit: If successful, this approach could help preserve cognitive function in patients undergoing treatment for brain metastases.

How similar studies have gone: While there is ongoing research in hippocampal-sparing techniques, this specific approach is relatively novel and has not been extensively tested.
