Terje Peetso, MD from the European Commission, Brussels, Belgium, discusses challenges associated with storing data electronically at the European Cancer Congress of the European Cancer Organisation (ECCO) 2017 in Amsterdam, Netherlands. A big challenge in terms of information and communication technology is awareness. The vast majority of Europe are very efficient at storing data electronically, however the data is not shared, and a real benefit of digital data is not being exploited. Another challenge is how to engage patients in the collection and incorporation of data into the system.
