  1. Alcohol consumption and breast cancer oestrogen and progesterone receptor status.

    Article - En anglais

    We examined the role of alcohol on the risk of breast cancer by the joint oestrogen receptor (ER) and progesterone receptor (PR) status of the tumour using data from two case-control studies conducted in Los Angeles County, USA.

    Eligible premenopausal patients were 733 women aged <= 40 years and first diagnosed from 1 July 1983 to 1 January 1989.

    Eligible postmenopausal patients were 1169 women aged 55-64 years and first diagnosed from 1 March 1987 to 31 December 89.

    Patients were identified by the University of Southern California Cancer Surveillance Program.

    Neighbourhood controls were individually matched to patients by parity (premenopausal patients) and birth date (± 3 years).

    ER and PR status were obtained from medical records for 424 premenopausal and 760 postmenopausal patients.

    The analyses included 714 premenopausal and 1091 postmenopausal control subjects.

    Alcohol use was generally not associated with premenopausal risk of breast cancer, regardless of hormone-receptor status.

    Among the postmenopausal women, those who consumed, on average, >= 27 g of alcohol/d experienced an odds ratio (OR) of 1.76 [95% confidence interval (Cl) 1.14-2.71] for ER-positive/PR-positive breast cancer relative to women who reported no alcohol consumption.

    Alcohol use was less clearly associated with risk of other receptor types among postmenopausal women.

    These data suggest that alcohol may preferentially increase risk of ER-positive/PR-positive breast cancer in postmenopausal women.
