Jeroen’s 538km Run Raises Funds for Princess Máxima Center & Child Cancer Research

Four years after the loss of his son Kasper to an aggressive brain tumor, Jeroen van Veen is running 538 kilometers to raise funds for the Princess Máxima Center for pediatric oncology. This extraordinary effort, beginning on March 6, 2026, is a deeply personal tribute and a powerful call for increased research and support in the fight against childhood cancer.

The Weight of Loss, the Power of Action

Jeroen’s journey began after his four-year-old son, Kasper, succumbed to a brain tumor. According to reporting from AD.nl, Jeroen now runs an average of ten kilometers daily, a grueling commitment sustained by his determination to honor Kasper’s memory and help other families facing similar tragedies. The run isn’t just about distance. it’s a fundraising campaign directly benefiting the Princess Máxima Center, a leading institution dedicated to pediatric oncology research and care.

Princess Máxima Center: A Hub for Pediatric Cancer Research

The Princess Máxima Center (Prinses Máxima Centrum) is a specialized hospital in the Netherlands focused exclusively on the diagnosis and treatment of childhood cancer. Established to consolidate expertise and accelerate research, the center brings together oncologists, surgeons, researchers, and support staff under one roof. Jeroen Hassink, a hospital pharmacist at the center, is responsible for managing the drug supply chain, highlighting the complex logistical operations required to deliver advanced cancer therapies to young patients. The center’s research efforts span a wide range of areas, including immunotherapy, targeted therapies, and early detection methods.

Beyond the Run: Community Support and Awareness

Jeroen’s initiative has garnered significant support from the Dutch community. Radio 538, a popular Dutch radio station, has been actively promoting the run, with presenter Bas Smit publicly praising Jeroen’s dedication to the cause. Dutchcowboys reports that Jeroen is running to raise money for the Prinses Máxima Centrum. Even local children’s daycares are contributing, having already raised over €53,000 for the center, as reported by Middelburgse Veerse Bode. Prins Pieter-Christiaan also participated in a fundraising event at the Radio 538 studio, further amplifying the campaign’s reach. RTL.nl covered this event, showcasing the widespread support for the cause.

The Challenge of Pediatric Oncology

Childhood cancer remains a significant health challenge. While survival rates have improved dramatically in recent decades, many children still succumb to the disease, and those who survive often face long-term health consequences from treatment. Brain tumors, like the one that took Kasper’s life, are particularly aggressive and difficult to treat. Research at the Princess Máxima Center focuses on developing more effective and less toxic therapies, as well as improving early detection methods to increase the chances of successful treatment. The center’s collaborative approach, bringing together experts from various disciplines, is crucial for tackling the complexities of pediatric cancer.

Prospact’s Support and Jeroen’s Motivation

Jeroen van Veen is being sponsored by Prospact, and PMC (via startpage), as highlighted on Prospact’s blog. This sponsorship underscores the importance of corporate partnerships in supporting vital research initiatives. Jeroen’s motivation extends beyond simply raising funds; he aims to create lasting memories with his family while honoring Kasper’s legacy. The blog post details the attractive memories Jeroen, Kasper, and the family created together, adding a poignant layer to his already inspiring endeavor.

Looking Ahead: Continued Research and Fundraising

The funds raised through Jeroen’s run will directly support research projects at the Princess Máxima Center, contributing to advancements in the diagnosis and treatment of childhood cancer. The center’s ongoing research efforts will likely focus on personalized medicine approaches, tailoring treatment plans to the specific genetic characteristics of each child’s tumor. Further investigation into immunotherapy, harnessing the power of the immune system to fight cancer, also holds significant promise. Continued fundraising initiatives, like Jeroen’s run, are essential for sustaining these vital research programs and ultimately improving outcomes for children battling cancer. The impact of this run extends beyond the immediate financial contribution; it raises awareness, inspires hope, and demonstrates the power of community support in the face of profound loss.
