Can a phone app help lung cancer patients breathe better after surgery?
NCT ID NCT06732193
First seen Jun 24, 2026 · Last updated Jun 26, 2026 · Updated 1 time
Summary
This study tests whether using a smartphone app (Fissios App) for breathing exercises, in addition to in-person physiotherapy, can reduce complications after lung cancer surgery. About 560 adults with non-small cell lung cancer scheduled for surgery will be randomly assigned to either standard in-person physiotherapy alone or the same plus the app. The main goal is to see if the app helps lower the rate of post-surgery problems like infections or breathing difficulties.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- respiratory physiotherapy (in-person sessions and a smartphone app)
- What this could lead to
- If the app works well, it could give patients a convenient way to do breathing exercises at home, possibly reducing complications after lung cancer surgery.
- What could go wrong
- This is a mid-sized trial, and the app is meant as a supplement, not a replacement. Results may vary depending on how well patients use the app, and it may not lower complication rates significantly.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Patients over 18 years of age. 2. Indication for lung resection surgery due to diagnostic suspicion or histopathological diagnosis of non-small cell lung carcinoma. 3. Anatomical lung resection surgery: anatomical segmental resection, lobectomies or pneumonectomies, using a conventional or minimally invasive approach (VATS, RATS). 4. The patient has a smart mobile device compatible with the Fissios App©, has the ability or has the support to use it. 5. Willingness and commitment to participate in the study. 6. Ability to complete the informed consent to participate in the study. Exclusion Criteria: 1. Medical contraindication to perform respiratory physiotherapy exercises. 2. Not possessing a smart mobile device compatible with Fissios App©. 3. Inability of the patient to perform the exercises, either due to a physical or psychological impediment. 4. Inability to complete the informed consent form for participation in the study. 5. Refusal to participate in the study.
