BACKGROUND: This cross-sectional study was carried out in a population-based setting in Worcestershire to investigate the relationship between social deprivation and other potential prognostic factors. METHODS: A total of 762 female @entity1 diagnosed with primary @entity0 between 1 January 1998 and 31 December 1999 were selected. @entity0 included all new cases of primary @entity0 and @entity513 in situ. A total of 753 @entity1 were matched by their postcode of residence to enumeration district Townsend score and then divided into three groups based on Townsend quintiles (affluent n = 478; middle n = 157; deprived n = 118). Main outcome measures were relationships between social deprivation and @entity5 type, stage at presentation, @entity2931 receptor status, @entity5 grade and treatment type. RESULTS: Compared with the most deprived @entity1 , affluent @entity1 were less likely to present with @entity5 (70.8 per cent versus 85.9 per cent, chi2 linear trend = 6.757, p = 0.009), @entity5 of higher grade (36.0 per cent versus 44.7 per cent, chi2 linear trend = 4.201, p = 0.040), and @entity2931 receptor negative @entity5 (22.4 per cent versus 33.3 per cent, chi2 linear trend = 3.501, p = 0.061). There was no significant difference in stage or @entity5 size at presentation between deprivation groups. More deprived @entity1 with invasive @entity5 of less than 20 mm maximum diameter were significantly more likely to have mastectomies than affluent @entity1 (47.8 per cent versus 32.1 per cent, chi2 linear trend = 4.091, p = 0.043). CONCLUSIONS: This study suggests that level of social deprivation is associated with @entity5 type, grade and @entity2931 receptor status. There was also a suggestion that increased level of deprivation was associated with increased risk of potentially unnecessary mastectomies.
