"Keep It Short and Simple": Perceptions of patients and healthcare professionals on the use of a mobile health app in the care for patients undergoing radical prostatectomy.

Background: Patients undergoing radical prostatectomy for localised prostate cancer generally have good long-term survival rates. However, late recurrences can occur and require lifelong follow-up.

Objective: This research aims to investigate different stakeholders' perceptions on the use of mobile health (mHealth) applications for prostate cancer follow-up after radical prostatectomy.
