What was measured
The percentage of participants without TR of the present breast cancer (i.e., the TR-free rate) and corresponding 95% CI were estimated by Kaplan-Meier analysis based on available data at the time of the 8-year median follow-up analysis. TR included local, regional, or distant tumor ignoring contralateral breast cancer and second non-breast malignancy.
Analysis population: FAS Population
Groups in this outcome
Observation Arm
Participants who completed definitive surgery and systemic adjuvant chemotherapy were observed for efficacy and safety until 10 years from individual randomization and for survival until 10 years after enrollment of the last participant. No Herceptin was provided.
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.
