Brock University Lung Nodule Malignancy Model
Estimates probability of malignancy in incidental pulmonary nodules detected on CT. Based on the Pan-Canadian Early Detection of Lung Cancer Study. Guides surveillance and biopsy decisions.
Score interpretation
Malignancy probability < 5 %
→ Routine follow-up per Fleischner/BTS guidelines; no urgent action required
Intermediate malignancy probability (5–10 %)
→ CT follow-up at 3–6 months to assess growth; discussion at MDT
Malignancy probability ≥ 10 % — the BTS threshold for further assessment (PET-CT)
→ Urgent MDT discussion; PET-CT; bronchoscopy or CT-guided biopsy; early surgical or oncological referral
Interpretation bands for the Brock Lung Model. Apply clinical judgement and local guidance.
