E. Celentano et al., DOES A RELATIONSHIP EXIST BETWEEN TRENDS IN ESTROGEN-RECEPTOR LEVELS AND BREAST-CANCER INCIDENCE AND MORTALITY, International journal of oncology, 13(1), 1998, pp. 129-135
Estrogen receptor data from 4,049 patients with primary breast cancer
treated at the National Cancer Institute of Naples between 1984 and 19
96, have been evaluated to analyze temporal trend of this tumor marker
. The prevalence rate of estrogen receptor levels falls from >75% in w
omen older than 60 years to <70% in younger patients. The analysis of
these data by birth cohort shows a trend very similar to that of breas
t cancer incidence in Italy, suggesting that the breast cancer appeara
nce could be modulated in different period of life.
