Understanding nausea caused by radiation in patients with benign brain tumors

Characterization of Nausea Induced by Radiation of the Dorsal Vagal Complex in the Context of Benign Brain Tumors (NausiCAA)

Observational University Hospital, Bordeaux · NCT06506578

This study is trying to see if the amount of radiation given to a specific area in the brain affects how much nausea patients with benign brain tumors feel during and after treatment.

What this trial studies

This observational study aims to evaluate the relationship between radiation dose to the dorsal vagal complex (DVC) and the incidence of nausea in patients with benign brain tumors. By utilizing validated questionnaires, the study will assess nausea levels at the end of radiotherapy and at one and three months post-treatment. The goal is to establish a dose threshold for the DVC that could help radiation oncologists optimize treatment plans and minimize nausea. This multicenter, non-interventional approach builds on previous findings linking DVC irradiation to nausea, but focuses specifically on benign brain tumors.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 years old with a diagnosis of benign brain tumors who are undergoing conventional radiation therapy.

Not a fit: Patients with a history of brain or head and neck radiation, concurrent chemotherapy, or those currently experiencing nausea may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved quality of life for patients by reducing radiation-induced nausea.

How similar studies have performed: Previous studies have shown a correlation between DVC irradiation and nausea in other contexts, but this specific approach in benign brain tumors is novel.
