We are delighted to invite you to the 6th International Symposium on Childhood, Adolescent, and Young Adult Hodgkin Lymphoma (ISCAYAHL), which will take place from October 15-18, 2025, in Berlin, Germany. Over the past 14 years, this symposium has become an essential platform for scientists and clinicians involved in the research and treatment of Hodgkin lymphoma in children, adolescents, and young adults.

As in previous years, we expect a rich exchange of the latest research findings and new ideas, as well as discussions on how these discoveries can be applied to clinical practice. Topics of focus will include survivorship outcomes, global clinical trial portfolios, novel therapeutic biomarkers, advances in lymphoma biology, and innovative imaging techniques. We also aim to share insights from global collaborations and foster new partnerships. A highlight of the upcoming symposium will be the Hodgkin Lymphoma Survivor Panel Discussion, moderated after the session on survival and aftercare, offering our former patients a platform to contribute to the conference.

In collaboration with our esteemed Scientific Committee, we are curating a high-quality program featuring renowned international speakers and experts in the field. The symposium will span two and a half days and cover ten main session topics, all open to abstract submissions. The Günther-Schellong Prize for outstanding contributions to the field of Hodgkin lymphoma will be awarded for the fourth time. The event will conclude with the Abstract Award Session.

The symposium will be held at the Langenbeck-Virchow-Haus, located in the heart of the historic Charité University Medical Center in Berlin. Many of you may recall this iconic and convenient venue, where we hosted the 2nd ISCAYAHL in 2014.

We are truly honored to continue offering this significant symposium for our global network, which strives to advance science and establish standards of care for children, adolescents, and young adults with Hodgkin lymphoma. We are eager to see this network thrive with your help in spreading this invitation globally. Your participation will contribute to the ongoing success of this network, and you will have the opportunity to experience firsthand the spirit and impact of this collaboration, which is dedicated to providing sustained cures and quality of life for all affected individuals.

Sincerely,
