In childhood, adolescence and young adults (CAYA), melanoma is under-studied and non-existing tailored clinical guidelines and standardized approaches lead to a very low diagnostic accuracy. The MELCAYA project aims to understand risk factors and determinants of melanoma to improve the prevention, diagnosis and prognosis of melanomas in CAYAs through a strong international consortium with experts from 10 countries in different disciplines (e.g. oncology, paediatrics, ethics, policy making), and sectors (e.g. academic centers, SMEs, hospitals, patient associations). MELCAYA will work on different approaches. 1) By integrating existing reference European cohorts and registries, studies of genetic and environmental risk factors and progression of melanoma in CAYA will be performed through different omic methods, and a novel taxonomy of CAYA melanoma will be generated. 2) MELCAYA will also develop image-based robust and trustworthy machine learning tools and a pan-European second-opinion platform for better diagnosis specifically designed for CAYA. 3) Moreover, the validation of minimally and non-invasive disruptive tools based on artificial intelligence and volatilomics detection from exhaled breath and skin will lead to earlier detection and more accurate prognosis of melanoma in CAYA. 4) Finally, through the evidence gathered, MELCAYA will design and implement public health strategies and will actively involve patients and the general population. The results of MELCAYA will maximize its impact by making its data and results accessible and re-usable through integration into UNCAN.eu. This action is part of the Cancer Mission cluster of projects on ‘‘Understanding".

STRONG-AYA is a new, interdisciplinary, multi-stakeholder European network to improve healthcare services, research and outcomes for Adolescents and Young Adults (AYA) with cancer, defined as individuals aged 15-39 years at cancer diagnosis. AYAs with cancer form a unique group; they face age-specific issues (e.g. infertility, unemployment, financial problems) and decreased quality of life due to cancer and its treatment. Unlike dedicated healthcare and trials for pediatric cancer patients, AYA-specific healthcare services are scarce and vary across Europe. AYAs who are at the core of society and economy need access to age-adjusted and high-quality healthcare. AYA-care and research will benefit from collection and pooling of patient-centered data and collaboration among all stakeholders: patients, healthcare professionals, scientists, and policymakers. Our consortium of clinical and scientific leaders in AYA-care, data science and registries, European Cancer Organisation, Youth Cancer Europe and EORTC will build on previous initiatives and EU grants. Within STRONG-AYA we will set up a value-based healthcare research ecosystem to develop data-driven, interactive policy and visualization tools that bring, in co-creation with all stakeholders including patients, novel insights into AYA healthcare. The project objectives, include: 1) Development of a Core Outcome Set (COS) for AYAs with cancer; 2) Implementation of the COS in 5 national healthcare systems (FR, IT, NL, UK, PL) and establish national infrastructures for outcome data management and clinical decision-making and a pan-European ecosystem that also welcomes future European countries; 3) Disseminate outcomes and facilitate interactions between national and pan-European stakeholders to develop data-driven analysis tools to process and present relevant outcomes, establish feedback loops for AYA cancer patients and the healthcare systems, and improve the reporting and assessment of outputs towards policy-makers.

Ventricular tachycardia (VT) is an unpredictable and potentially deadly condition and should be promptly treated with catheter ablation and medication, before irreversible and potentially fatal organ damage follows. Unfortunately, this combination of treatments does not prevent VT reoccurrence in 30-50% of VT patients and while they can undergo multiple invasive ablations, technical difficulties or refusal of the patient can lead to a lack of effective treatment options. A promising novel, non-invasive treatment option for VT is stereotactic arrhythmia radioablation (STAR). Besides being non-invasive, STAR can also be used to reach locations that are inaccessible for catheter ablation, which may potentially improve effectiveness of overall VT treatment. Small scale first in men/early phase trials have been performed for STAR, providing proof-of-concept for clinical safety and efficacy. However, patients with recurrent VT are not a homogenous group and each center deals with different inclusion criteria, imaging and/or target definition. Many questions remain and the available studies lack the power to clinically validate the approach and prepare for late stage phase III trials. The STOPSTORM consortium sets out to consolidate all current and future European efforts to clinically validate STAR treatment by merging all data in a validation cohort study, standardising pre-treatment and follow-up, in order to collect the data sets and statistical power needed to unanimously establish clinical safety, efficacy and benefit for STAR. The STOPSTORM consortium also sets out to refine protocols and guidelines, determine volumes of interest, define and model the optimal target region and target dose, also in relation to surrounding healthy tissues (i.e. organs at risk) and determine which patient population and underlying cardiopathies respond best to STAR. By doing so the STOPSTORM consortium paves the way to consensus and future late stage clinical trials for STAR.

Cancer is the second leading cause of death in Europe with an expected increase of about 25% by 2035. A wide and unacceptable variability in terms of access to research, innovation and quality care exists between and within countries. Possible solutions are an increase in knowledge by funding research, and a more equitable transfer of what we already know to everyone. Comprehensive Cancer Centers and Comprehensive Cancer Care Networks may be the core of CCIs that deliver quality care and provide resources to improve and integrate care, research and education. Data already available confirm that the level of "CCI maturity" in Member States is widely different, from some countries lacking CCIs completely. A European initiative, implemented in all Member States, based on a capacity building programme (CBP), will help reduce inequalities, in the context of other actions ongoing, such as CRANE, JANE and UNCAN. CBP is a complex intervention that requires multiple and integrated actions delivered to all the relevant stakeholders. CBP will be designed with an inclusive approach, tailored to the baseline status, capable of creating a change and improvement in research and care, with greater integration between them, supported by an education programme. It will operate at various levels: Individuals, Institutions and Systems. The CSA will implement the following steps: define CCI Maturity Model including quality indicators; profile the CCIs in each MS and a few ACs in terms of CCI presence and levels of maturity; design tailored CBP interventions, giving priority to MSs without any CCI; deliver online training courses open to teams in all MSs and ACs, implement targeted onsite interventions; scale up and sustain development; disseminate, exploit and report results. The CSA will maximize impact by bridging with the work of ongoing EU cancer research projects. National focal points will be key informants in making the links between the CSA, the EC and MSs.
