A 2017 review of radiation oncology apps included a study that reported 157 products for radiation oncology professionals (46 iOS apps and 111 Android apps) and 25 patient-focused apps.11

Some apps might be useful both in clinical settings and as clinical research tools.12-14 Researchers at Vanderbilt University in Nashville, Tennessee, and the University of Vermont in Burlington, reported that an experimental real-time pain-reporting app for patients with head and neck cancer undergoing cancer radiotherapy showed promise as an “ecological momentary assessment” tool for gathering patient-reported outcomes (PROs), which are increasingly used as clinical trial outcomes measure.12 Use can be improved by allowing patients to set app threshold alarm thresholds for 2-way communication with their cancer care team, the authors suggested.12

mHealth Apps and Features

Cancer apps for patients tend to fall into seven broad categories:

  • Community apps
  • Cancer care team connection apps
  • Education apps
  • Smoking cessation apps
  • Symptoms and treatment tracker apps
  • Coping, calming, and pain management apps
  • Sleep and fatigue management apps

With the proliferation of popular topic- and cancer-specific social media platform patient discussion groups, such as Facebook cancer patient groups, the community features of cancer patient mHealth apps will likely become less useful to patients than other app features. However, with more than 1000 user ratings at the Play Store, the CaringBridge app appears to remain a popular way for patients to update friends and loved ones during treatment for cancer and other diseases, in a single place.15

Some apps include features from more than one of these categories. For example, the Rads4Kids app has both a treatment calendar and journal as well as education features to help prepare children with cancer and their parents for radiation therapy, explaining radiotherapy with a children’s storybook (in English and French), an interactive game that helps kids understand radiotherapy, and a frequently asked questions (FAQ) section for teens and parents.16,17

Generic mHealth apps and chemotherapy-oriented apps can be useful during radiotherapy as well. chemoWave, for example, is a symptoms- and mood-tracking app that creates charts for patients; logs their sleep patterns, vital statistics, meals, water intake, and steps taken; and issues appointment and medication reminders.18 It also allows patients to share their logged experiences with others, including their cancer care team members.18 Patient reviews at the Play Store show that it is being used by radiotherapy patients.

The CareZone app reminds patients and their caregivers at home of medication schedules and appointments and allows them to review treatment plan notes.19

Untire is a cancer-related fatigue self-management app with education, symptoms tracking, and online community features that explain cancer- and cancer treatment-related fatigue, offers lifestyle tips and exercises, and weekly self-reporting of energy levels and fatigue.20 A protocol for a proposed randomized clinical trial of this product has been published but the trial has not yet been initiated.21 Chemo Brain similarly tracks patients’ self-reported cognitive performance issues during cancer treatment and includes prescription reminders.22
