Cancer- healthcare, research and innovation face core common challenges, such as fragmentation of initiatives and distancing from important stakeholders, requiring coordinated solutions. These challenges are recognized in Horizon Europe’s Cancer Mission Implementation Plan and in Europe’s Beating Cancer Plan. The proposal Establishing of Cancer Mission Hubs: Networks and Synergies (ECHoS) represents a unique opportunity to coordinate R&I and Healthcare actions on cancer with policy-making processes creating transnational communication & collaboration networks aligned with Cancer Mission objectives. Experiences shows that the setup and implementation of innovative health solutions are more likely to be successful when a broad range of stakeholders and decision-makers from the public and private sectors are part of the process. By fostering the creation of National Cancer Mission Hubs (NCMHs) in member states and associated countries ECHoS will create the conditions for organized stakeholders and individual citizens to collaborate and engage in policy dialogues. The implementation of the Cancer Mission objectives will promote more resilient and people-centric healthcare and research systems. ECHoS will produce (i) general models and guidelines for the creation of sustainable NCMHs, (ii) a knowledge exchange programme to support development of NCMHs competences, (iii) impact models and training sets to help efficiently engaging with distinct stakeholders, (iv) a toolkit for synergies to help NCMH engaging in collaborative work with individual European Initiatives, (v) a business continuity model envisaging long-term sustainability of a EU network of NCMHs and (vi) a calendar of events to create awareness on NCMHs and to help closing the gap in citizens’ participation in cancer policy. In summary, ECHoS will create conditions for NCMHs to be Mission Cancer advocates in MS/AC and set the pace for the development of a transnational network of NCMHs in a second phase.
