Lancet 2011]. The Adjuvant Tamoxifen: Longer Against Shorter [ATLAS] trial compared the effects of continuing tamoxifen for a total of 10 years with stopping after the standard 5 years of treatment. This article presents data from the ATLAS trial on the effect of tamoxifen on 15-year survival [Davies C et al. Lancet 2012].
