Treatment of early localized breast cancer in elderly patients by Tamoxifen.

Twenty-seven early localized breast cancer cases in elderly patients, 21 stage I and six stage II, were treated with Tamoxifen only. In 15 cases there was complete radiological remission and in seven cases partial remission or growth arrest. Five cases did not respond to treatment. Tamoxifen seemed to be a useful alternative treatment for this group of patients. Possibly tumour mass and growth rate may affect the response to antioestrogen treatment.
