Interventions

Diagnostic intervention with the 70-gene microarray profile giving a result of 'high' or 'low' risk for distant metastasis and death.

Eligibility

Sex/Gender

Female

Inclusion criteria

Inclusion criteria: 1. Female patients 2. With primary operable unifocal breast cancer 3. Without clinical signs of lymph node involvement or distant metastasis 4. Younger than 55 years of age

Exclusion criteria

Exclusion criteria: A prior history of any malignancy with the exception of cervical dysplasia and basal cell carcinoma.

Design outcomes

Primary

Measure	Time frame
The amount of successfully performed diagnostic microarray tests as a proportion of the total number of accrued patients.	—

Secondary

Measure	Time frame
1. To assess the proportion of a 'high' versus a 'low' risk profile in lymph node negative breast cancer patients 2. To assess the concordance between the 70-gene microarray risk profile and the metastasis risk as assessed with current Dutch guidelines based on clinicopathological factors (such as age, pT, tumor grade, hormonal receptor-status)	—
