The year 2025 was a defining and forward-looking year for Childhood Cancer Switzerland. As President, I was particularly pleased to witness two important milestones: the launch of our digital information plat- form and the establishment of our new Public Affairs & Communications department. Through the new information platform, developed in close collaboration with our member organisations, we have succeeded in closing an important gap. Our goal was always to provide children affected by can- cer and their families with reliable, easy-to-under- stand and readily accessible information about the disease and life after treatment. The platform not only serves as a source of knowledge but also offers guidance, helps reduce fears and uncertainty, and represents a significant milestone that fills me with great confidence. At the same time, we have strengthened our voice at the political level. With the new Public Affairs & Com- munications department, we are now able to advo- cate even more effectively for the needs of children, adolescents and their families. I am convinced that this enables us to make a meaningful contribution to improving framework conditions for access to thera- pies, reducing the burden on families in everyday life and creating fair future prospects. We also opened a new chapter in our Executive Man- agement team: with Elena Guarnaccia as our new CEO, I look forward to fresh ideas and the continued development of our organisation. In her new role, I wish her every success, fulfilment and enjoyment. Another special moment for us was the 10 th anniver- sary of Childhood Cancer Switzerland. This milestone was not only an occasion to celebrate but also a time for reflection: over the past ten years, we have achieved a great deal together with our member or- ganisations, partners and supporters. At the same time, it reminded us how important our continued commitment remains. We see this anniversary as an opportunity to carry our mission forward with the same determination and sense of responsibility into the future. Despite all the progress, one goal remains at the heart of our work: to stand by children and adolescents with cancer and their families and support them, especially during the most difficult moments of their lives. My sincere thanks go to our Executive Management team, my colleagues on the Board, our member or- ganisations and all our supporters. Your commitment makes our work possible. Together, we ensure that every child affected by cancer in Switzerland receives the best possible care and support. Thank you from the bottom of my heart. Prof. Dr. med. Nicolas von der Weid President Childhood Cancer Switzerland Editorial by the President “Sustainable improvements for children with cancer are achieved where research, care and political framework conditions come together.” 4

I assumed the role of CEO of Childhood Cancer Swit- zerland in spring 2025 with great motivation and deep respect. At the heart of our work are children and ad- olescents with cancer and their families – people who need our support, and whose voices deserve to be heard. It is a privilege for me to contribute to this mis- sion personally. Every year, around 350 children and adolescents in Switzerland are diagnosed with cancer. Behind this number are not just statistics, but stories – stories of courage, hope, resilience, but also uncertainty and tremendous challenges. At the same time, these sto- ries inspire us to advocate for better access to care, a better quality of life after treatment and stronger sup- port for research. Over the past year, together with our member organ- isations, we achieved important progress. We strength- ened collaboration and networking across support services, launched new initiatives for Survivors and their families, and advocated strongly for improved policy framework conditions. Each of these steps rep- resents tangible improvements in the lives of those af- fected – and demonstrates what can be achieved when we join forces. A particularly special moment was the 10th anniver- sary of Childhood Cancer Switzerland. Ten years of shared commitment to children affected by cancer and their families. This anniversary is above all a rea- son for gratitude – towards everyone who helped build, shape and support our organisation. At the same time, the launch of our new information plat- form marks another important milestone and a fitting highlight of this anniversary year. This forward-looking resource improves access to reliable information and support for affected families, healthcare professionals and the wider public. The anniversary also reminds us of our responsibility to continue this journey with de- termination and to further strengthen our impact in the future. Looking ahead is essential. Three priorities guide our work: the consistent promotion of research, the sus- tainable support of those affected and their families, and greater awareness among society and policymak- ers of the needs of children with cancer. Only by work- ing together can we create the conditions needed to turn hope into tangible opportunities and lasting change. We are also continuing to strengthen our organisation for the future. As Childhood Cancer Switzerland has grown and evolved, it became clear that new premis- es were needed. In March 2026, we therefore relocat- ed to Rittergasse 20 in the heart of Basel’s city centre. This move provides a modern environment that re- flects our expanding responsibilities. At the same time, it strengthens collaboration within our team and with our member organisations and partners – because meaningful impact is always achieved together. My heartfelt thanks go to our dedicated team, our Board, our member organisations and everyone who contributes their expertise, commitment and com- passion to our vision. Each of you helps us provide hope, guidance and new perspectives. Together, we stand alongside children affected by cancer, adoles- cents, Survivors and their families – today and in the future. Elena Guarnaccia CEO Childhood Cancer Switzerland Message from the CEO “The challenges remain significant, but so does our commitment. Together, we continue to strengthen and develop Childhood Cancer Switzerland, ensuring that children affected by cancer, Survivors and their families receive the support they need most.” 5

Thanks to your support, together with our member organisations we are able to stand by children, adolescents, Survivors and families affected by cancer – providing support, opportunities and hope. Your Support Matters – Facts and Figures 1 500 000 invested in childhood cancer research over the past five years 35 000 awarded annually through our research prize to support young researchers 1 new digital information platform with information, resources, personal stories and more 3 social media channels raising awareness of the needs of those affected 250 Survivors participated in our programmes and services 280 articles informing and raising awareness 14 events for Survivors and parents, creating space for exchange, guidance and new perspectives 6

What has been achieved over these ten years demon- strates what is possible when people come together around a shared goal. Important milestones such as paid caregiving leave for parents of seriously ill chil- dren and improved access to life-saving medicines reflect this collective commitment. Behind these achievements lie not only political progress, but above all tangible relief, new opportunities and a greater sense of security in the everyday lives of affected families. Yet our work extends far beyond numbers and ac- complishments. Its impact is reflected in moments of hope, renewed strength and the reassurance of knowing that no one has to face this journey alone. None of this would be possible without your support. You help us expand our projects, make essential ser- vices accessible and provide support where it is need- ed most. Together with our member organisations, we stand alongside children and adolescents with cancer, their families, Survivors and their parents – offering hope, courage and renewed confidence. What unites us is more than commitment. It is the deep conviction that even in the most difficult mo- ments, light can emerge when we are there for one another. Ten Years of Impact – Bringing Hope Together In 2025, Childhood Cancer Switzerland celebrated its 10 th anniversary. Ten years during which we have supported children, adolescents and their families, opened up new opportunities, and passed on hope. Since 2015, we have worked with conviction to improve the quality of life of children and adolescents affected by cancer, Survivors and their families in a sustainable way. 7

This is precisely why our shared commitment is so important. As the umbrella organisation, we bring together the strengths of Switzerland’s leading child- hood cancer organisations with one clear goal: to sustainably improve the quality of life of children and adolescents affected by cancer, Survivors and their families, and to support them throughout their journey. We raise awareness of childhood cancer and shine a light on life after treatment. We advocate for children affected by cancer and Survivors to receive the long- term support they need. At the same time, we ensure that their voices are heard at the political level and work towards fair framework conditions: access to ef- fective therapies, coordinated lifelong Follow-up Care, and strong, forward-looking childhood cancer research. All of this is made possible through dedicated fund- raising efforts and the support of committed individu- als. Their contributions provide the foundation for us to further develop our services, create new opportu- nities and sustainably improve the quality of life of children affected by cancer and Survivors. Our motiva- tion is clear: no child and no family should have to face this journey alone. Childhood Cancer in Focus – Small Hearts, Big Courage Every year, around 350 children and adolescents in Switzerland are diagnosed with cancer. A number that may seem abstract at first glance, yet one that represents life-changing moments that turn lives upside down in an instant. Thanks to advances in medicine, significantly more young people survive cancer today than in the past. However, many continue to live with long-term physical or emotional consequences that extend far beyond treatment. Unser Einsatz konzentriert sich auf fünf zentrale Bereiche: Kinderkrebsforschung Public Affairs & Kommunikation Sensibilisierung Our work focuses on five key areas: Childhood Cancer Research Public Affairs & Communications Awareness Raising Follow-up Care Fundraising 8

That is why we are committed to making childhood cancer visible and drawing attention to what happens after treatment. We want not only to inform, but also to inspire, raise awareness and foster understanding. What becomes visible can be changed. Through national awareness campaigns, targeted me- dia engagement and digital formats, we reached many people in 2025. We shared personal stories, provided insights and highlighted where action is still needed. Raising Awareness – Making Childhood Cancer Visible Through our channels on Instagram, Facebook and LinkedIn, we make childhood cancer visible and reach a broad audience. We tell stories, share personal ex- periences and offer insights into the lives of those af- fected – honest, approachable and moving. With regular info series, Survivor portraits, personal quotes, event announcements and thematic focus topics, we create opportunities for information and dialogue. We also direct people to our website and in- formation platform, where reliable knowledge and practical support are readily available. Social Media and Awareness Raising A cancer diagnosis turns the lives of children, adolescents and their families upside down from one moment to the next. Alongside intensive treatment, the emotional and social challenges often shape everyday life – fears, uncertainty and countless questions that have no simple answers. Childhood cancer brings unique challenges that require special attention and a deep understanding. Our goal is clear: children and adoles- cents with cancer and their families must not be overlooked – they should be able to rely on understanding, support and solidarity. 10

In 2025, we established our Public Affairs & Communi- cations department to bring the concerns of children with cancer and their families more effectively into political processes and to raise awareness among de- cision-makers in politics and healthcare about their specific needs. Our focus is on ensuring equitable access to effective therapies, reliable legal and regulatory framework conditions, and the sustainable strengthening of re- search and Follow-up Care. Public Affairs & Communications – Giving a Voice to Children with Cancer Childhood cancer requires specific healthcare policy framework conditions. To ensure that children, adolescents, Survivors and their families receive the best possible care, long-term follow-up support and fair opportunities, strong advocacy at the political level is essential. Progress is only possible when we act together. “Children with cancer have specific needs. Our responsibility is to bring these into political processes and to create framework conditions that enable high-quality care, follow-up support and research.” Laura Kundert, Public Affairs & Communications We would like to extend our sincere thanks to Dr. med. Pierluigi Brazzola for his many years of valuable commitment and are delighted to welcome Prof. Dr. med. Katrin Scheinemann as our new health policy expert for Childhood Cancer Switzerland. 11

“Despite everything, Oscar remained a curious young boy. His strength and joy for life continue to give us courage as a family.” Camilla, mother of Survivor Oscar Oscar underwent intensive cancer treatment as a baby. Today, at ten years old, he and his family have been part of our journey for just as long. His story reminds us that surviving cancer is not the end, but often the beginning of a new chapter. It highlights the importance of long-term Follow-up Care, understanding and exchange with other af- fected families. We sincerely thank Oscar’s family for their trust over the years and wish them many joyful and carefree moments, as well as all the very best for the future. The services include legal counselling, information and guidance on Follow-up Care, education and ca- reer development, as well as personalised support programmes such as application and career coaching. These are complemented by initiatives such as the “Write Your Story” programme, which helps Survivors process challenging experiences and develop new perspectives. Other important elements include regular gatherings in both German-speaking and French-speaking Swit- zerland, themed weekends, and the WeCanDays – a professionally facilitated weekend designed to pro- mote exchange, activity and self-confidence. Dedicat- ed support services are also available for parents of Survivors, providing guidance on late effects, Follow-up Care and social and legal matters. Follow-up Care for Life After Childhood Cancer Today, most children survive cancer. However, more than 80 percent live with long-term effects that may impact their health, emotional well-being, social life or professional future. This makes Follow-up Care a central pillar of our work. Through our national centres of expertise for Survivors and for parents of Survivors, we provide unique support services in Switzerland for former childhood cancer patients and their families.

Stronger Together for Meaningful Moments Insights from Survivor gatherings across Switzerland, where exchange, understanding and connection take centre stage. “The Survivor gatherings give me the feeling of being understood. Meeting others who have had similar experi- ences strengthens and encourages me.” Moreno, Survivor 13

Our New Information Platform – Everything at a Glance A childhood cancer diagnosis turns the life of an entire family upside down. Many parents describe the mo- ment by saying, “It felt as though the ground had been pulled from beneath our feet.” Suddenly, they are faced with countless questions and fears about the disease, treatment, possible long-term effects and a profoundly changed family life. In such a challenging situation, access to clear, reliable and evidence-based information is often lacking. The need for easily accessible knowledge about childhood cancer is therefore immense – from diagnosis and treatment to long-term Follow-up Care. The information platform developed by Childhood Cancer Switzerland guides affected families step by step along this journey. It explains medical topics in an understandable way, provides information on Fol- low-up Care and support services, and helps families find their bearings in a new reality. At the same time, it fosters connection and exchange among those af- fected. In summer 2025, Childhood Cancer Switzerland launched its new information platform. It brings together reliable information on childhood cancer and is designed for parents, Survivors, relatives and anyone seeking information on the topic. The platform offers practical guidance on questions such as: • What is childhood cancer and how do we talk about it as a family? • How can we organise our new daily life? • What rights do parents and caregivers have, and what should they be aware of? • Where can we find counselling and financial support? The information platform was developed and imple- mented jointly by experts, people with lived experi- ence and the member organisations of Childhood Cancer Switzerland. “Being an affected mother myself, I know that a cancer diagnosis turns the life of an entire family upside down. Reliable information, exchange with others and a strong community are all the more important in supporting families beyond treatment.” Susanne Studiger, Vice President 14

TogetherWeCan – A Personal Story Nicole is a fighter. Growing up in a farming family, giving up was never an option. At the age of four, she was diagnosed with cancer. Many memories have faded over time – but she still remembers her worried family and the hospital. She survived, lost a kidney, and fought her way back into life. She never stops moving forward. So she keeps going. Achieves more, stays strong – out- wardly unwavering, inwardly driven. “I never learned how to slow down,” she says today. Years later, exhaustion catches up with her. Long-term effects, fatigue and personal crises push her to her limits. Suddenly, nothing works anymore. For the first time, Nicole begins to listen to herself. She allows herself to be strong not only in difficult times, but also to acknowledge her own needs. And she realises that creating space for this was necessary so that trust, joy and what had long been missing could find a place again. Today, she speaks openly about what she had to learn herself: “You don’t always have to be strong. It’s okay to slow down.” When New Hope Grows from Looking Inward “I want to tell other Survivors that it’s okay to take things more slowly, to have doubts and ask ques- tions, and that they do not have to feel obliged to appear strong all the time.” Nicole, Survivor 16

Because children develop different types of cancer than adults and medicines for children are often less readily available, childhood cancer research remains a highly important field with considerable potential for improvement. Childhood Cancer Switzerland supports epidemiologi- cal and clinical projects through its member organisa- tions – particularly through the Swiss Paediatric On- cology Group (SPOG) and the Childhood Cancer Research Group at the University of Bern (ISPM). These studies investigate the causes and progression of diseases, long-term effects, and modern diagnostic and therapeutic approaches. Their aim is to improve quality of life, physical activity, heart and lung func- tion, and the early detection of long-term complica- tions. As public funding for childhood cancer research in Switzerland remains limited, Childhood Cancer Swit- zerland plays an important role in enabling progress and improving access to modern treatments over the long term. Childhood Cancer Research – Innovation for Better Outcomes Although survival rates have increased significantly over recent decades, children in Switzerland still die from cancer, and many Survivors live with long-term effects. “Every investment in childhood cancer research is an investment in more cures, fewer long- term effects and better future prospects for children and adolescents who have survived cancer.” Dr. med. Heinz Hengartner, Board Member Basic research contributes to a deeper scientific un- derstanding of cancer and is essential for advancing new approaches to its treatment. To support this field, Childhood Cancer Switzerland has awarded an annual Basic Research Award in paediatric oncology since 2020. The award is aimed at early-career researchers conducting innovative and forward-looking projects at Swiss research institutions and hospitals. In 2025, the The Childhood Cancer Switzerland Basic Research Award award was presented to Matteo Bimbati from the Uni- versity Children’s Hospital Zurich. His research focuses on improving treatment strategies for one of the most aggressive childhood brain tumours. 18

Interview with Matteo Bimbati Recipient of the Childhood Cancer Switzerland Research Award What is the focus of your research project, and why is it relevant for children with cancer? My research project focuses on improving treatment strategies for diffuse midline glioma (DMG), one of the most aggressive brain tumours in childhood. One of the few therapies currently available is ONC201, a targeted treatment that initially shows promising results but often loses effectiveness over time because tumour cells develop resistance. The aim of my project is to better understand why DMG cells become resistant to ONC201 and how these re- sistance mechanisms can be overcome. This should help improve the effectiveness of treatment while also considering the development and quality of life of affected children. What impact could your research have on affected children and their families in the long term? In the long term, the research aims to develop more effective and durable treatment strategies for chil- dren with DMG by better understanding the biological principles behind therapies such as ONC201. For af- fected children and their families, this could mean im- proved treatment outcomes over time and more tol- erable therapies that help preserve quality of life. Which framework conditions are particularly im- portant to enable progress in research into such rare and severe diseases? Because rapid action is crucial in DMG, research must be supported quickly and in a coordinated manner. Central factors include close collaboration between research centres, access to patient data, a sustainable research infrastructure and improved diagnostic pos- sibilities to ensure that new findings can be translated into clinical practice more quickly. What personally motivates you in your work? What motivates me is the great medical need and the opportunity to make a meaningful contribution in a field where there are currently very limited treatment options. DMG is one of the most severe childhood cancers, and even small scientific advances can make a significant difference for affected children and their families. “Through the consistent support of childhood cancer research, we enable progress that leads to better therapies, fewer long-term effects and the best possible treatment opportunities for children affected by cancer, both today and in the future.” Dr. med. Nicolas Waespe, Board Member 19

When businesses and charitable commitment come together, meaningful impact is created. Childhood Cancer Switzerland is deeply committed to advancing childhood cancer research so that cancers in children become increasingly treatable and survival rates con- tinue to improve. The goal of our fundraising efforts is to use available resources efficiently and create the greatest possible impact for children affected by cancer, Survivors and their families. As a non-profit organisation, Childhood Cancer Swit- zerland relies entirely on donations and partnerships. Numerous foundations and companies from a wide range of sectors already support our mission, sending a strong message of solidarity and social responsibility. Key priorities include supporting research projects, funding our Survivorship Centres of Expertise, and de- veloping new information and support services. We place great importance on ensuring that donations are used sustainably and provide direct benefits to those affected. Each year, private individuals, foundations, companies and volunteer initiatives support Childhood Cancer Switzerland through charity events, sporting activi- ties, creative projects and long-term partnerships. Fundraising & Partnerships – Creating Impact Together The diverse activities of Childhood Cancer Switzerland – from awareness raising and advocacy to Follow-up Care and research – are only possible thanks to private donations and project-based funding. Joining Forces for Children with Cancer Sharing Hope – Shaping the Future By making a testamentary gift, you have the opportuni- ty to create a lasting impact beyond your lifetime. Whether through a donation that can be used where it is needed most, or by supporting a specific project – every contribution is of great importance. It enables us to continue developing our services, promote research and support children affected by cancer, adolescents, Survivors and their families in the future where it mat- ters most.

Kinderkrebshilfe Schweiz Kinderkrebshilfe Schweiz is there when families hear the words: “Your child has cancer.” These words turn the life of an entire family upside down in an instant. As a non-profit organisation, Kinderkrebshilfe Schweiz pro- vides practical and straightforward assistance to affected families – from those who have experienced child- hood cancer themselves, for those who are facing it today. Since 1987, the organisation has been one of the first points of contact in German-speaking Switzerland for families affected by childhood cancer. It supports them through challenging times – during and after treatment. Its services include activities and holidays that bring moments of joy into everyday life, direct financial assistance to ease burdens, dedicated support for be- reaved families, and Follow-up Care programmes that help improve quality of life.
