Outcomes
Primary Outcomes
The presence of a specific predictive gene expression signature in tumor tissues
Time Frame: At randomization and at definitive surgery which may be up to 30 weeks post randomization.
The presence of other candidate biomarkers in tumor tissues
Time Frame: At randomization and at definitive surgery which may be up to 30 weeks post randomization.
Disease free interval
Time Frame: Time from definitive surgery to the date of first recurrence of the disease up to maximally 6 years.
The presence of immune infiltration in tumor tissues
Time Frame: At randomization and at definitive surgery which may be up to 30 weeks post randomization.
The pathological response (complete response or partial response) in the breast.
Time Frame: At definitive surgery which may be up to 30 weeks post randomization.
Disease free survival
Time Frame: Time from definitive surgery to either the date of first recurrence of the disease or the date of death (whatever the cause), whichever occurs first, up to maximally 6 years.
Overall survival
Time Frame: Time from definitive surgery to the date of death, irrespective of the cause of death. Patients still alive will be censored at the date of the last contact up to maximally 6 years.
