Digital therapeutics (DTx) have been defined as technologies that "offer therapeutic interventions driven by high-quality software programs, based on scientific evidence obtained through methodologically rigorous confirmatory clinical investigation, to prevent, manage and treat a broad spectrum of physical, mental and behavioural conditions". DTx products are on the market in a number of countries or under development for a broad range of physical and behavioral conditions, including oncology treatment management. The aim of this narrative review is to provide an update on findings available for DTx, specifically developed for the treatment of patients with cancer. A search was conducted using the following databases: PubMed, Google Scholar, Clinicaltrials.gov and Deutsches Register Klinischer Studien, as well as some websites specifically concerned with DTx.
