EVENTS, RECURRENCE, SECOND PRIMARY CANCER, CARCINOMA IN SITU
The primary endpoint was disease-free survival (DFS). Secondary endpoints were overall survival (OS), BCSM, and other-cause mortality (OCM). The following events ended a period of DFS: BC recurrence, second primary BC, second primary cancer (excluding basal cell or squamous cell carcinoma of the skin and carcinoma in situ of the cervix), or death from any cause. A period of OS ended as a result of death from any cause. All BC-related deaths were included in the analysis of BCSM, whereas all non-BC-related deaths were included in the analysis of OCM.
