What was measured
DFS events included loco-regional or distant recurrence of breast cancer, development of contralateral breast cancer or second non-breast malignancy other than basal or squamous carcinoma of the skin and carcinoma in situ of the cervix, or death from any cause. The percentage of participants free of DFS events (i.e., the DFS rate) and corresponding 95% CI were estimated by Kaplan-Meier analysis based on available data at the time of the final analysis with a 10-year maximum follow-up for DFS events.
Analysis population: FAS Population 1Y2Y
Groups in this outcome
Herceptin 1-Year Arm
Participants who completed definitive surgery and systemic adjuvant chemotherapy received a loading dose of Herceptin as 8 mg/kg via IV infusion on Day 1, followed by a maintenance dose of 6 mg/kg via IV infusion 3 weeks later and thereafter every 3 weeks for 1 year or until disease recurrence, whichever occurred first. Participants were observed for efficacy and safety until 10 years from individual randomization and for survival until 10 years after enrollment of the last participant.
Herceptin 2-Year Arm
Participants who completed definitive surgery and systemic adjuvant chemotherapy received a loading dose of Herceptin as 8 mg/kg via IV infusion on Day 1, followed by a maintenance dose of 6 mg/kg via IV infusion 3 weeks later and thereafter every 3 weeks for 2 years or until disease recurrence, whichever occurred first. Participants were observed for efficacy and safety until 10 years from individual randomization and for survival until 10 years after enrollment of the last participant.
