{"denomUnitsSelected":"Participants","description":"Disease-free survival (DFS) is defined to be time from randomization to first event, where the first event is any of ipsilateral breast tumor recurrence, local recurrence, regional recurrence, distant recurrence, contralateral second primary invasive cancer, second primary non-breast invasive cancer (excluding non-melanoma skin cancers), or death without evidence of recurrence. The distribution of DFS (eg, 5-year DFS rate) is estimated using Kaplan-Meier method. 5-year DFS by individual RS gene groups (Proliferation Gene Group, HER2 Gene Group, ER Gene Group, Invasion Gene Group, and Other Genes) will be estimated in each arm.","reportingStatus":"NOT_POSTED","timeFrame":"Assessed every 6 months within 5 years from registration and then annually up to 20 years","title":"5-year Disease-free Survival by Individual RS Gene Groups","type":"SECONDARY"}
