Histopathological characteristics and oestrogen receptor content in primary breast carcinoma.

159 primary breast carcinomas were examined histologically with regard to grade of anaplasia, cellularity, amount of elastic tissue, and whether they were of ductal or lobular origin. Possible correlations between these variables and the oestrogen receptor (OR)-content were investigated. There was a marked tendency toward a greater number of OR-positive tumors in the group rich in elastosis.

Adjuvant endocrine therapy of breast cancer--a controlled clinical trial of oestrogen and anti-oestrogen: preliminary results of the Copenhagen breast cancer trials.

In an attempt to clarify the value of adjuvant endocrine therapy as an alternative to other treatment modalities, we have started two controlled, prospective, double-blind trials, the Copenhagen Breast Cancer Trials. In these studies postmenopausal women are randomised after primary local treatment to treatment with DES, tamoxifen, or placebo. Premenopausal women are similarly randomised to receive treatment with tamoxifen or placebo.
