A Reminder App to Optimize Bladder Filling in Patients with Prostate Cancer Receiving HYPO-fractionated Radiotherapy

Condition(s) studied

Investigational drug(s) / intervention(s)

Reminder App: The purpose of the app is to remind patients irradiated for prostate cancer in an intuitive, unobtrusive and supportive way to drink 300 ml of water 45 minutes prior to each radiation session.

Study summary

The primary goal of this study is to assess the impact of an app that reminds patients treated with hypofractionated radiotherapy (HF-RT) for prostate cancer to drink water prior to each radiotherapy session on the number of bladder volumes \<200 ml during the HF-RT course and to demonstrate that this number is lower than without using an app (historical control group).

Eligibility

Primary outcome measure(s)

• Number of fractions with bladder volumes <200 ml at the end of the radiotherapy course — through study completion, an average of 4 weeks
  The primary endpoint is the number of radiation fractions with bladder volumes \<200 ml at the end of the radiotherapy course. The bladder volume at each radiation fraction is calculated from the corresponding Cone-Beam Computed Tomography (CBCT).
