8 Prognostic (Recurrence Risk) Predictive (Treatment Benefit)
Prognostic & Predictive Markers Used in Breast Cancer Management Prognostic (Recurrence Risk) Predictive (Treatment Benefit) •Axillary node status •Histologic type/grade •Tumour size •Patient age •Lymphatic/Vascular invasion •ER/PR status •HER2 neustatus •Endopredict •Prosigna •uPAPAI1 •OncotypeDX® test •ER/PR status •HER2 neustatus •OncotypeDX® test Sunali Mehta et al: Predictive and prognostic molecular markers for cancer medicine.

9 The Oncotype DX® Breast Cancer Test
16 Cancers and 5 Reference Genes from 3 studies It is a 21 gene genomic test (16 tumourgenes and 5 reference genes). • Uses RT-PCR technology on formalin fixed tissue. • Quantitatively predicts the likelihood of breast cancer recurrence in women with newly diagnosed, invasive EBC. • Is the only assay that has been demonstrated to be predictive of likelihood of benefit from chemotherapy. • Is included clinical practice guidelines (St Gallen, ESMO, ASCO®, NCCN®) and NICE4-7 Proliferation Ki-67 STK 15 Survivin Cyclin B MYBL2 OESTROGEN ER PR Bcl-2 SCUBE 2 GSTM1 BAG1 Invasion Stromelysin 3 Cathepsin L2 CD86 Reference b-actin GAPDH RPLPO GUS TFRC HER2 GRB7 Harris L, et al.

10 Elements of analytic validation
OncotypeDX (Genomic Health, USA) Elements of analytic validation • Analytical sensitivity (limits of detection and quantitation) • Assay precision and linear dynamic range • Analytical reproducibility • PCR amplification efficiency • Sample and reagent stability • Reagent calibration • Instrument validation and calibration
