Preoperative diagnostic accuracy of dominant lesion in multifocal pulmonary nodules.

ABSTRACT:

Background

Due to the widespread implementation of computed tomography (CT) in lung cancer screening, multifocal pulmonary nodules (MPNs) are increasingly detected. Given the importance of selecting preoperative dominant lesions (DLs) in the management of MPNs, this study evaluates the diagnostic accuracy of commonly used approaches for assessment of preoperative DLs.

Methods

Patients who underwent surgical resection and CT for MPNs from May 2019 to September 2023 were retrospectively collected from a single center. The postoperative DLs were determined based on the pathology results. Four methods were employed to identify preoperative DLs including diameter, Mayo model, Brock model, and Peking University multiple pulmonary nodules malignancy prediction model (PKU-M model) a
