Brief summary
Chemo-N0 (1993-1998) is the first prospective randomized multicenter trial in N0 BC designed to prospectively evaluate the clinical utility of a biomarker. It used uPA/PAI 1 as stratification criteria and randomized high-risk patients to chemotherapy versus observation; low-risk patients remained without any systemic therapy. The trial was designed to answer two principle questions: 1. Can the reported prognostic impact of uPA and PAI 1 be validated in a prospective multicenter therapy trial? Does low uPA/PAI 1 identify those low-risk N0 patients who are candidates for being spared necessity and burden of adjuvant chemotherapy? 2. Do uPA/PAI 1 high-risk patients benefit from adjuvant CMF chemotherapy?

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Prognostic impact of uPA/PAI-1: Number of patients disease-free in low vs. high risk groups according to uPA/PAI-1 | DFS at 3, 5, and 10 years (depending on analysis time point) | Interim analyses planned at 4.5, 6.5, and 8.5 years after first patient in. Final analysis scheduled at 10.5 years after last patient in. |
| The benefit of adjuvant chemotherapy in high-risk group according to uPA/PAI-1: Number of patients disease-free vs. those relapsed at the given time points | DFS at 3, 5, and 10 years (depending on analysis time point) | Interim analyses planned at 4.5, 6.5, and 8.5 years after first patient in. Final analysis scheduled at 10.5 years after last patient in. |
Secondary
| Measure | Time frame | Description |

| Overall survival | at 3, 5, and 10 years (depending on analysis time point). | Interim analyses planned at 4.5, 6.5, and 8.5 years after first patient in. Final analysis scheduled at 10.5 years after last patient in. |
