Scientific titleThe implementation of microarrays in cancer diagnosis (microarray prognostics in breast cancer)
Study acronymRASTER
Study objectivesRecently we have identified a gene expression profile of 70 genes using microarray analysis, which was a more powerful prognostic factor for freedom of distant metastases than current clinicopathological features in node negative breast cancer patients up to 55 years of age. To assess whether this 70-gene microarray test can be implemented in daily clinical practice we aimed to answer the following three questions:
1. Is it feasible to collect fresh tumour samples in order to make this test available in pN0 breast cancer patients in community hospitals?
2. What is the proportion of a ‘high’ versus a ‘low’ risk profile in node negative patients?
3. What is 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, tumour grade, hormonal receptor-status)?

Primary hypothesis: The implementation of microarray diagnostics is feasible in general practice in community hospitals.
Ethics approval(s)Approval received from the local ethics committee (Protocol Toetsingscommissie) on the 8th October 2003 (study ref: MO3ARR; letter ref: EV03-464).
Health condition(s) or problem(s) studiedBreast cancer
InterventionDiagnostic intervention with the 70-gene microarray profile giving a result of 'high' or 'low' risk for distant metastasis and death.
Intervention typeOther
Primary outcome measureThe amount of successfully performed diagnostic microarray tests as a proportion of the total number of accrued patients.
Secondary outcome measures1. 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)
