| Popis: | In a previous report three year survival rates in breast cancer were related to geography, socio-economic status and age at first pregnancy. Here, results from 5 years of follow-up observations are summarized with respect to incidence risk factors. Age-adjusted 5 year survival rates were 57·3% in Boston, Massachusetts, 49·5% in Glamorgan, Wales, 41·9% in Slovenia, Yugoslavia, and 74·9% in Tokyo, Japan; corresponding age-adjusted annual incidence rates per 100,000 were 55·0, 38·8, 24·4 and 12·9 . Although survival rates varied markedly among these areas, there was not a consistent relationship between incidence rate and probability of survival. Differences in survival rates between Boston, Glamorgan and Slovenia were reduced when examined according to extent of disease at diagnosis, but the relatively high survival rate in Tokyo was not explained. Survival rates tended to increase, although inconsistently, with increasing socioeconomic status as measured by duration of schooling. Probability of survival was not related to childbearing or, for parous patients, to age at first full-term birth. |
