Within the HOVON structure, there are three types of work groups:
- Disease-specific work groups, made up of experts in the field of for example acute leukemia, lymphoma, chronic lymphatic leukemia, multiple myeloma, chronic myeloid leukemia or myeloid proliferative neoplasia and benign hematology. In these work groups, discussions are held about new trials and recommended treatments.
- Treatment Specific Modality work groups consisting of Stem cell transplantation, Supportive care, Immune effector cell and LLPC. These working groups provide support to the disease-specific working groups and are responsible for supporting the disease-specific working groups in a specific domain.
- Technical committees, that consist of experts in the field of diagnosis and monitoring. Examples are the molecular biology working group, the imaging group and pathology review.
