NCT ID NCT04568278
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether a mobile app helps cancer patients undergoing chemotherapy or radiation therapy report their symptoms more effectively. Over 200 participants used the app to track side effects for 8 weeks. The goal was to see if the app improves how patients recognize and communicate symptoms to their healthcare team.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- mobile application for symptom reporting
- What this could lead to
- If it works, this could help cancer patients better communicate their symptoms to doctors, potentially improving care.
- What could go wrong
- This is a completed study with 222 participants, but it focuses on reporting behavior, not direct health outcomes. The app may not change actual symptom management or quality of life.
