This proposal for a European Cancer Patient Digital Centre (ECPDC) Information Portal, EU-CIP, addresses the information needs of cancer patients, survivors, relatives, and caregivers. EU-CIP aims to create a patient-centric cancer information portal that improves health literacy, empowers patients, and reduces inequalities in access to cancer care information across Europe. The EU-CIP primary goal is to improve quality of life and enhance cancer patient care by improving access to general and personalized knowledge, delivering comprehensive information on cancer prevention, early detection, diagnosis, and treatment options including risks, side effects and late effects as well as information on rehabilitation and management of recurrence and palliative care. EU-CIP will prioritise high-incidence cancers, those with poor prognosis, and paediatric cancers. A Common Library of Contents available to all Member States will be created and EU-CIP nodes will be deployed in 10 Member States. The Library of Contents will use information from evidence-based sources such as the Knowledge Centre on Cancer and the European Cancer Information Service, existing Cancer Information Portals, and European guidelines. A governance framework for scalable content creation and review processes supported by AI tooling will be established. The consortium partners, including several patient organisations, will ensure that the patients’ view is reflected in the content review and technology usability aspects. The EU-CIP Central and local nodes will be built in a modular fashion to allow integration with existing electronic health infrastructures. To align with the EU Cancer Mission goal to improve lives through prevention, EU-CIP will raise awareness about the Mission and Europe’s Beating Cancer Plan. Alignment with the Mission’s overall plans will be realized through collaboration with the EU funded projects of the related 01-01/01-02 calls.
