Data Resource Profile: Yorkshire Specialist Register of Cancer in Children and Young People (Yorkshire Register).

Data resource basics Cancer is a rare disease in children and young people[8],[9] and is commonly defined such that it includes any malignant tumour or benign central nervous system (CNS) tumour. Innovative data linkages with routinely collected administrative data facilitate the Yorkshire Register's world-leading programme of research on childhood and young-adult cancer outcomes, extending into ground-breaking areas of social and psychosocial morbidity. Key Features The Yorkshire Register is an established population-based research database of tumours diagnosed in the childhood, adolescent and young-adult age ranges.[1] Set up in 1984 to describe medium- and long-term outcomes for cancer survivors, it remains one of only three specialist databases in the UK covering the paediatric age range and the only one of its kind covering individuals diagnosed aged 25-29 years. 5 SMNs are defined as a malignant neoplasm of any site with a different morphology from that of the primary tumour regardless of time since diagnosis according to the recommended coding of multiple primary cancers.[21],[22] 6 ICCC-3, International Classification of Childhood Cancer (third edition)[20]; CNS, central nervous system.
