Can a smartphone app ease the mind for kidney cancer patients?
NCT ID NCT04788095
First seen Jun 24, 2026 · Last updated Aug 20, 2026 · Updated 3 times
Summary
This study is testing whether a smartphone app that teaches mindfulness can help people with advanced kidney cancer cope with their illness. The trial will enroll 21 patients who are already receiving immunotherapy and have moderate to high fear of their cancer returning. The main goal is to see if patients will actually use the app and complete the study questionnaires, not yet to prove it improves quality of life.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- app-based mindfulness program
- What this could lead to
- If it works, this could offer a simple, low-cost way to help people with advanced kidney cancer feel less anxious and depressed.
- What could go wrong
- This is a very small early study (21 people) testing only whether the app is usable, not whether it truly improves health. Results may not apply to everyone.
