Brock model for pulmonary nodules
The Brock model, also known as the PanCan model, is a multivariable model that estimates the risk that a pulmonary nodule on CT scan is lung cancer.
The model was developed from participants enrolled in the Pan-Canadian Early Detection of Lung Cancer Study , has been validated in lung cancer screening and clinical populations , and is recommended by the British Thoracic Society guidelines for pulmonary nodules .
Predictors of lung cancer in the Brock model :
- older age
- female sex
- family history of lung cancer
- emphysema
- larger nodule size
- upper lobe nodule location
- part-solid nodule type
- lower nodule count
- spiculation
By providing an estimate of nodule lung cancer risk, the Brock model can assist in determining appropriate follow-up and management of pulmonary nodules detected on CT.
