Socioeconomic inequalities in cancer survival in Scotland 1986-2000.

We analysed trends in 5-year survival of the 18 commonest cancers in Scotland diagnosed between 1986 and 2000 and followed up to 2004 in each of five deprivation groups based on patients postcode of residence at diagnosis. We estimated relative survival up to 5 years after diagnosis, adjusting for the different background mortality in each deprivation group by age, sex and calendar period. We estimated trends in overall survival and in the deprivation gap in survival up to 2004. Five-year survival improved for all malignancies except bladder cancer and was associated with a widening in the deprivation gap in survival. For 25 of 30 cancer-sex combinations examined, 5-year survival was lower among more deprived patients diagnosed during 1996-2000, and the deprivation gap in survival had widened since 1986-1990 for 15 of these 25 cancers, similar to the trends seen in England and Wales.
