Clinical Context & Background
The Magee Equations are prediction models that estimate the Oncotype DX® Recurrence Score (RS) using standard pathology variables (Nottingham Score, Ki-67, ER/PR H-Scores, Tumor Size). This helps clinicians identify patients who are likely to have a low RS and might avoid expensive genomic testing.
Formula Logic
RS ≈ 15.31 + (1.50 × Nottingham) - (0.05 × ER H-Score) - (0.03 × PR H-Score) + (0.14 × Ki67) + (0.54 × Tumor Size)Reference Data
| Est. Recurrence Score | Risk Category (TAILORx) |
|---|---|
| 0 - 25 | Low / Intermediate Risk |
| 26 - 100 | High Risk |
