Classification and incidence of cancers in adolescents and young adults in England 1979-1997

Cancer patients aged 15-24 years have distinct special needs. High quality cancer statistics are required for service planning. Data presented by primary site are inappropriate for this age group. We have developed a morphology-based classification and applied it to national cancer registration data...

Description
Summary:Cancer patients aged 15-24 years have distinct special needs. High quality cancer statistics are required for service planning. Data presented by primary site are inappropriate for this age group. We have developed a morphology-based classification and applied it to national cancer registration data for England 1979-1997. The study included 25,000 cancers and 134 million person-years at risk. Rates for each diagnostic group by age, sex and time period (1979-83, 1984-87, 1988-92, 1993-1997) were calculated. Overall rates in 15-19 and 20-24-year-olds were 144 and 226 per million person-years respectively. Lymphomas showed the highest rates in both age groups. Rates for leukaemias and bone tumours were lower in 20-24 year olds. Higher rates for carcinomas, central nervous system tumours, germ-cell tumours, soft tissue sarcomas and melanoma were seen in the older group. Poisson regression showed incidence increased over the study period by an average of 1.5% per annum (P
