In recent years, the intersection between immunodeficiencies, haematologic conditions, and oncology has become ever more apparent. As we witness increasing complexity in patient diagnoses and treatments, the need for a collaborative, multidisciplinary approach is more critical than ever. This symposium aims to provide a comprehensive platform for exploring how immunodeficiencies can influence hematologic and oncologic conditions and vice versa, and how each specialty offers unique insights that contribute to improving diagnosis, treatment, and management strategies. By putting our patient in the centre and working across disciplines we can build a future where they receive the optimal healthcare.​

Connect with clinical experts and researchers in Vienna, 18-20 November 2025 to:​

• Explore the pathophysiological and clinical interplay between these fields.​
• Discuss the latest clinical practices.​
• Expand joint research.​

Join us at the ESID-EHA-SIOPE Focused Symposium 2025 to explore the “Interplay of Immunology & Haematology” and improve the care of our immunodeficiency, haematology and cancer patients.
