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

Low Probability (< 5%) 0–4.99

Malignancy probability < 5 %

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

Intermediate Probability 5–9.99

Intermediate malignancy probability (5–10 %)

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

High Probability (≥ 10%) 10–100

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
