Relationship of oestrogen-receptor status to survival in breast cancer
Lancet (London, England)
|August 11, 1979
Abstract:
The oestrogen-receptor (E.R.) content of the primary tumour was measured in 133 postmenopausal women with operable breast cancer. 79 (59%) were positive for E.R. and 54 (41%) negative. Curves of life survival show that women with E.R.-positive tumours live longer than those with E.R.-negative tumours.
