Target In July 1999, the UK government set a ‘tough but attainable’ target: to reduce the death rate from cancer in people under 75 by at least a fifth by 2010 (compared with 1997) - saving up to 100,000 lives

Death rates from cancer depend on: l incidence –several years ago l survival –over the past few years
l We can decrease the incidence through prevention. l We can improve survival through better treatment.
Can starting prevention strategies now affect the incidence enough to reduce the death rate by 2010?
Smoking accounts for l over one third of cancer deaths –lung, mouth, larynx, oesophagus and other cancers l about one fifth of other deaths –mainly from circulatory and respiratory disease
l Survival has improved. l If it continues to improve, roughly 24,000 deaths will be avoided by 2010 l If survival for everyone were as good as survival of the most affluent, about 41,500 deaths would be avoided.
Eliminating social class differences - in both incidence and survival - would almost certainly save more lives in the next decade than innovative treatments.

Children’s cancer - a success story Why? l many childhood malignancies are chemosensitive - and among the first for which curative chemotherapy was developed l rare disease - so a manageable problem
Why? l treatment at regional centres l cross-speciality communication l evidence-based treatment l national collaboration in treatment protocols l most patients entered into clinical trials Children’s cancer - a success story
l Can adult cancer be treated as successfully as children’s cancer? l Can we give everyone the best care, irrespective of their social status?
Good statistics are the crucial underpinning of government policy.
Statistics are needed for: l valid target setting l planning service delivery l audit of performance
High quality statistics: l accurate l complete l timely
What sort of statistics? l incidence} { age l mortality} by { sex l survival} { tumour type
How do we use the statistics? l to analyse trends l to analyse factors affecting trends l to predict the effects of these factors as the age structure of the population changes
Health care has taken the lead in calling for evidence based decisions; government policy likewise needs to be determined by a firm knowledge base.
I work on the epidemiology of children’s cancer. I previously taught English to people from other countries - mainly Bangladesh and Pakistan - who had settled in England. I integrated health education into my English teaching. This work made me more aware of the inequalities in society, both within England and between different countries. Heather Dickinson
l Learning objectives - to understand: factors influencing cancer incidence and survival stratifying by age, sex, social class national statistics on disease l Performance objectives - to assess: national trends in disease rates targets for reduction in mortality
