The Organisation of European Cancer Institutes (OECI) is a non-governmental, non-profit organisation established in Vienna in 1979 and restructured in 2005 as a European Economic Interest Grouping (EEIG). Headquartered in Brussels, OECI brings together over 170 cancer centres across Europe and beyond, fostering a collaborative network dedicated to improving cancer training, research and care.

Our mission is also to enhance the quality of cancer care by promoting multidisciplinary, patient-centred approaches and facilitating the integration of research, education, and clinical practice. Through our programmes, activities and Working Groups, we support member institutions in achieving excellence in comprehensive cancer care.

OECI actively participates in European initiatives contributing to policy development and the establishment of a cohesive European cancer area.

By uniting expertise and resources, OECI strives to reduce cancer incidence and mortality, ensuring equitable access to high-quality care for all patients.
