Brief Summary:

The trial population of this study is composed of women aged more than 18, who have developed a newly node-negative (or pN1mi), Estrogen Receptor (ER)-positive, Her2-negative invasive breast cancer with uncertainty on the indication of adjuvant chemotherapy using standard assessments.

Obtaining material for test is at no risk as done from the surgery material. Tumor molecular EndoPredict (EP)clin analysis will allow to obtain information on the expression of 8 breast cancer related genes and will provide important prognosis indications. Clinical validation studies have demonstrated that molecular assays are useful for stratifying patients into risk categories and helpful in making clinical treatment decisions in ER+/node-negative breast cancer patients.

Arm Intervention/treatment
EndoPredict (EP)clin testing
Once the patient is registered, the most representative block of the primary tumor from surgery (or 10 paraffin slides) are sent to the central analysis platform for EP clin testing. The EPclin method is based on analysis of tumour genes in combination with the classical prognostic factors of nodal status and tumour size.
 Other: EPClin genomic test


Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. The proportion of patients whose choice of treatment is changed as a result of receiving the EPclin genomic test result [ Time Frame: 15 days ]

Secondary Outcome Measures :
  1. Impact of genomic test results on patient's quality of life (QoL), anxiety levels and satisfaction results using standardized "State-Trait-Anxiety Inventory" questionnaires compared with general condition at baseline. [ Time Frame: 1 year ]
  2. Time required by the centralized platform to perform the test (calculated from the biological sample receipt to the genomic test results). [ Time Frame: 1 year ]
