Program:Genetics and Genomics
Test Name:Prosigna for Breast Cancer
Performing Site: University of Alberta Hospital
Performing Dept:Molecular Pathology
Availability:Test set-up on Monday and Wednesday (excluding statutory holidays).
TAT:1 week
Preferred Tube/Container:See Specimen Requirements
Specimen Requirements:For Paraffin-Embedded Tissue:
Cut the block in the following order:
1.  1 x 4-micron Hematoxylin & Eosin (H&E) stained slide
2.  6 x 10-micron unbaked unstained charged slides
3.  1 x 4-micron Hematoxylin & Eosin (H&E) stained slide
Specimen Processing:The breast biomarker pathologist must circle the tumor area in the first H&E slide.
In addition, the breast biomarker pathologist needs to ensure that the tumor cellularity is >10% and the surface area is > 4 mm2.

Please provide a copy of the corresponding pathology report.
Additional Information:Please note: Aptex or Apex slides are not acceptable.
Electrostatically charged slides must be used.
Requisition/Form:All requests MUST be submitted on a Molecular Pathology Requisition.
Please provide any pertinent clinical history on the requisition.
Indications:To determine breast cancer recurrence risk in women with hormone receptor positive, HER2 negative, node negative breast cancers with equivocal clinico-pathologic characteristics. Test restricted to breast oncologists and pathologists.
Method:Gene expression profile
Method Details:Prosigna is a Health Canada approved test that uses a 50 gene expression profile, tumour size and nodal status to identify intrinsic subtype, report a Risk of Recurrence Score (ROR) and a probability of Distant Recurrence (DR). RNA is extracted from FFPE tissue, hybridized to the Prosigna CodeSet in the nCounter prep station and scanned by the nCounter Digital Analyzer.
