Tamoxifen Adjuvant Treatment Duration in Early Breast Cancer: Initial Results of a Randomized Study Comparing Short-Term Treatment With Long-Term Treatment

Abstract

Although no survival advantage was noted, patients did benefit from longer tamoxifen treatment over 3 years and had significantly better disease-free survival compared with patients who stopped hormonal treatment. Long-term follow-up is needed to assess these results. Most patients in the long-term group are still receiving treatment. Comparison of results as time passes will enable conclusions to be made on the value of long-term treatment over 5 years compared with 2 to 3 years.
