THE ANNUAL INCIDENCE of male breast cancer in the United States is dwarfed by the rate among women. Yet, for the estimated 2,670 men who will be diagnosed with breast cancer this year, life-extending and life-enhancing treatments are crucial.1 To help reduce knowledge gaps and improve mortality and ...

Ivana Sestak, PhD, of Queen Mary University of London and the Centre for Cancer Prevention, discusses study findings that confirm the prognostic ability of the Clinical Treatment Score at 5 years (CTS5) for late distant recurrence, specifically for patients older than 50 years and/or for those deemed to have intermediate- or high-risk hormone receptor–positive, HER2-negative, node-negative breast cancer. The CTS5 is less prognostic in women younger than 50 who received 5 years of endocrine therapy alone (Abstract GS4-03).
Hongchao Pan, PhD, of the University of Oxford, discusses an analysis of 86,000 women in the Early Breast Cancer Trialists’ Collaborative Group database, which showed that the risk of distant recurrence 20 years after a diagnosis of node-negative, estrogen receptor–negative early-stage breast cancer in women who discontinued endocrine therapy at 5 years is likely to be about a third lower now than in his group’s previous report (Abstract GS2-04).
