The outcome of treatment by age and socio-economic status was examined for 1,588 women with invasive cancer of cervix resident in the West of Scotland and diagnosed between 1980 and 1987. There was no difference in prognosis according to either variable once analysis was controlled for stage at presentation, treatment type and tumour grade. Tumour histology, date of treatment and health board of residence had no significant effect on survival independent of other variables. A strong correlation was found between socio-economic status and the incidence of cervical cancer in the West of Scotland. Women aged 45 and over and living in deprived areas were more likely to present with later stage tumours and to survive less well than younger patients from the more affluent parts of the region. Any additional resources which may be made available for cervical cancer screening should be directed more effectively towards those most at risk.
