The Children’s Cancer and Leukaemia Group (CCLG) was formed in 2006 as a result of the merger of the UK Children’s Cancer Study Group and the UK Childhood Leukaemia Working Party, both of which had been in existence since the 1970s. The CCLG supports the 1,700 children who develop cancer each year in the UK and Ireland. As an association for all healthcare professionals involved in their care, it works to benefit children through development of the highest standards of care. Many activities contribute towards this goal: education, meetings, networking, liaison with governments and other bodies, information provision for families and healthcare professionals, and the promotion of research. Through a network of specialist centres, members aim to provide the best possible treatment for all children with cancer and leukaemia, wherever they live. The work of CCLG members over the last thirty years means that over 70% of children with cancer are now cured; but further carefully conducted clinical research is essential until every child can be cured without serious side effects. CCLG – caring for children, curing their cancer.
