Log odds = (0.0287 x (Age - 62)) + Sex + Family history + Emphysema - (5.3854 x ( (Nodule size/10) - 0.5 - 1.58113883)) + Nodule type + Nodule in upper lung - (0.0824 x (Nodule count - 4)) + Spiculation - 6.7892 The log of odds and cancer probability determine the malignancy risk of the lesion (s) within the next 2-4 years. Lung nodules are usually about 0.2 inch (5 millimeters) to 1.2 inches (30 millimeters) in size. What are the causes? At present, the accuracy of these models in this setting is inferior to expert clinical judgment, and future work is needed to develop management algorithms for higher-risk nodules. Objective: To assess the performance of the Brock malignancy risk model for pulmonary nodules detected in routine clinical setting.
