The Australian and New Zealand Children’s Haematology Oncology Group (ANZCHOG) works with the COSA Paediatric Oncology Group. The aim of the Group is to ensure the best available therapy for all children with malignancies and haematological disorders.

ANZCHOG is involved in national and international clinical trials, clinical and laboratory based research, workshops, seminars and an annual scientific meeting.  The group within COSA also provides an opportunity for those concerned with the management of children to meet with interstate and international colleagues.
