Is this trial a fit for you?

Likely a good fit

Adults (18+) who previously had a pathologically confirmed cancer diagnosis, were treated with systemic cancer therapy, have persistent conditioned nausea and/or vomiting for more than two months, and can understand spoken and written Dutch are ideal candidates.

Probably not a fit

People currently in psychiatric treatment, those with dissociative or personality disorders, complex type 2 trauma, severe somatic contraindications, recent pregnancy, or substance abuse (or whose nausea is caused by non-cancer medications/conditions) may not benefit or are excluded.

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

What this trial studies

This interventional study will deliver Eye Movement Desensitization and Reprocessing (EMDR) therapy to adult cancer survivors who report persistent conditioned nausea and/or vomiting after systemic chemotherapy. Participants will receive a course of EMDR sessions at the University Medical Center Groningen and symptom severity will be measured before, immediately after, and at follow-up visits. The trial excludes people with ongoing psychiatric treatment, dissociative or personality disorders, complex type 2 trauma, severe somatic conditions, pregnancy, or substance abuse that could cause nausea. Results will compare symptom change to characterize whether EMDR reduces conditioned nausea and vomiting in this population.

Why it matters

Potential benefit: If successful, EMDR could reduce or eliminate conditioned nausea and vomiting and improve daily functioning and quality of life for cancer survivors.

How similar studies have gone: EMDR is well established for PTSD and has shown promising but limited positive results for conditioned nausea in small-scale reports, though rigorous trials are scarce.
