title: Oestrogen receptors and prognosis in early breast cancer.
abstract: In a study of the role of oestrogen-receptor analysis in early breast cancer the oestrogen-receptor content of the tumour was estimated in 286 patients undergoing mastectomy. These patients were followed for up to 39 months, and the recurrence of disease was noted in relation to the presence or absence of oestrogen receptor.Recurrence-rates were significantly higher in patients whose tumours did not contain receptors than in those whose tumours did. This same relationship was seen when women with and without axillary metastases were considered separately. The highest rates of recurrence were in women with axillary lymph-node involvement whose tumours lacked oestrogen receptors. Women without axillary-node involvement whose tumours lacked oestrogen receptors showed the same high rate of recurrence as all women with axillary-node involvement. The oestrogen-receptor content of a primary breast cancer appears to be an independent guide to early recurrence of the disease.
