Breast Cancer Recurrence (Post Mastectomy)

This model predicts risk of post simple mastectomy breast cancer recurrence. The data for this model came from a population with a 23% local recurrence rate.

Three Questions make up this prediction tool:

  1. Grade of Tumor
    • I (6 pts)
    • II (12 pts)
    • III (18 pts)
  2. Lymph node status
    • Negative (6 pts)
    • Positive (12 pts)
  3. Lymphatic or Vascular Invasion
    • None (4 pts)
    • Present (8 pts)

The points are summed. Recurrence risk is predicted from these 3 items.

Points % Recurrence
16 8.5%
20 12.5%
22 15.8%
26 10%
28 15.5%
32 33%
34 38.5%
38 48%
