The Lung Cancer App (LuCApp) study protocol: a randomised controlled trial to evaluate a mobile supportive care app for patients with metastatic lung cancer

LuCApp has been designed by a multi-disciplinary team and developed through iterative sessions to improve patients’ real-time monitoring of symptoms and side effects during pharmacologic therapies for lung cancer. The impact of LuCApp on health related quality of life, cancer supportive care needs, burden for caregivers and resource consumption will be tested in a parallel randomised controlled trial. Sources of bias may include the different levels of ease of participants when using mobile technologies, the impossibility to blind them and different modes of questionnaires administration (app-based vs paper/phone-based)
