Between November 1, 1976 and December 31, 1981, 826 post-menopausal females with operable breast cancer were included into a trial comparing tamoxifen 40 mg daily for 2 years with no endocrine treatment. Patients without axillary lymph node metastases and tumors less than 30 mm received no other treatment whilst those with more advanced disease were in addition superrandomised to receive postoperative irradiation or 12 courses of CMF. With a mean follow-up of 44 months tamoxifen significantly reduced the incidence of recurrence. There was no significant interaction between the effect of tamoxifen and any other treatment or prognostic subgroup.
