This involves removing a piece of the nodule for testing in a lab. Evaluation is guided by nodule size and assessment of probability of malignancy. Lung cancer is the leading cause of cancer-related deaths in the United States. A solitary pulmonary nodule is a well-circumscribed round lesion measuring up to 3 cm in diameter and surrounded by aerated lung. LungRADS calculator (version 1.1) Clinicians use prediction models to try to determine malignancy risk: Two common ones are the Mayo Clinic Solitary Pulmonary Nodule Malignancy Risk model for incidental nodules and the Brock University Calculator for nodules detected on lung cancer screening. The Brock model had the highest AUC for sub-centimetre pulmonary nodules. The purpose of this study is toshow a reduction in the proportion of benign lung nodules experiencing invasive procedures (biopsies or surgery) between a group of patients managed by standard of care with Nodify XL2 results and a group managed by standard of care blinded from NodifyXL2 results.

A multidisciplinary team of researchers at Mayo Clinic has developed a new software tool to noninvasively characterize pulmonary adenocarcinoma, a common type of cancerous nodule in the lungs. A clinical model to estimate the pre-test probability of lung cancer in patients with solitary pulmonary nodules. Small nodules are difficult to biopsy and not reliably characterized on FDG-PET scan. Computed tomography is the imaging modality of choice for reevaluating solitary pulmonary nodules visible on chest radiography and for subsequently monitoring nodules for change in size. Among 12,029 nodules found in a large Canadian study, only 144 (1%) were malignant.8. All rights reserved. 2/3 of all patients were found to have benign disease, with 23% having malignancy diagnosed. The risk of malignancy is also higher in spiculated lesions, in lesions with asymmetric calcification, and in lesions located in an upper lobe.8 In contrast, nodules with smooth borders and a central or concentric pattern of calcification are more likely to be benign (Figure 1). The workup for patients with solid solitary pulmonary nodules measuring 8 mm or greater in diameter, nodules measuring less than 8 mm in diameter, and subsolid nodules should be guided by the probability of malignancy, imaging results, and the risks and benefits of different management strategies.
