Primary Outcome Measures

Name	Time	Method
5-year invasive disease-free survival (IDFS) rate	up to 60 months	Invasive disease free survival was defined as the time from enrollment until the date of first occurrence of one of the following events: invasive ipsilateral breast tumor recurrence, local/regional invasive recurrence, distant recurrence (including first metastasis), invasive contralateral breast cancer, second primary invasive cancer (nonbreast, not including squamous or basal cell skin cancers, or new in situ carcinomas of any site), or death from any cause. 5-year IDFS rate is thepercentage of participants with IDFS from enrollment through 5 years.

Secondary Outcome Measures
