Survival of women with breast cancer in Europe : Variation with age, year of diagnosis and country.
Breast cancer is the most frequent malignancy among women in developed countries.
Prognosis is better than for other major cancers, and an improvement in survival has been reported for several populations in recent decades.
Within the framework of EUROCARE, a population-based project concerned with the survival and care of cancer patients in Europe, we analysed data from 119,139 women diagnosed with breast cancer between 1978 and 1985 in 12 countries and followed for at least 6 years.
Multiple regression models of relative survival, which take mortality from all other causes in each area into account, were used to estimate the effect of age, period of diagnosis and country on survival.
For the comparison between countries, survival rates were age-standardised to the age structure of the entire study population.
Women aged 40-49 years at diagnosis had the best prognosis in all countries and throughout the study period.
Women younger than 30 years at diagnosis had a worse prognosis than those aged 30-39.
The highest relative survival at 5 years was in Finland and Switzerland (about 74%), intermediate levels were found for Italy, France, The Netherlands, Denmark and Germany (about 70%) and the lowest rates were in Spain, the United Kingdom, Estonia and Poland (55-64%). During the 6 months following diagnosis, survival was highly dependent on age and was sharply lower in women older than 49 years. (...)
