test-directed treatment: allocated treatment will depend on the PAM50 score result (centrally assessed) : chemo-endocrine therapy or endocrine therapy alone

In this experimental arm, the treatment is driven by the score of the Prosigna test. If the score is superior to 60, the patient is considered at hight risk so the patient will receive chemo-endocrine therapy. If the result is under or equal to 60, only endocrine therapy will be prescribed to the patient.
