Brock University Lung Cancer Malignancy Score

Predicts malignancy probability in pulmonary nodules found on CT screening. Validated for nodules 6–30 mm. Used alongside Fleischner and BTS guidelines.

Score interpretation

Low Probability (<1.5%) 0–1.5

Low malignancy probability — routine screening interval appropriate

→ Routine follow-up per Fleischner/BTS guidelines; no urgent action required

Intermediate Probability 1.5–10

Intermediate malignancy probability (1.5–10%)

→ CT follow-up at 3–6 months to assess growth; discussion at MDT

High Probability (>10%) 10–100

High malignancy probability >10%

→ Urgent MDT discussion; PET-CT; bronchoscopy or CT-guided biopsy; early surgical or oncological referral

Interpretation bands for the Brock Score. Apply clinical judgement and local guidance.
