Accuracy of positron emission tomography in mediastinal node assessment in coal workers with lung cancer

摘要: The purpose of this study was to explore the accuracy 18F-fluorodeoxyglucose (FDG)-positron emission tomography/computed tomography (PET/CT) in assessment mediastinal lymph node coal workers who had non-small cell lung cancer. We retrospectively reviewed 42 retired cancer without distant metastasis, between May 2007 and 2010. Regarding nodes, when standard uptake value greater than 2.5, it considered “malignancy positive.” After histological examination anthracotic metastatic ones were detected. results PET/CT analyzed determine its accuracy. Of these patients, detected 47 positive nodes 24 patients with a mean SUV maximum 6.2 (2.6–13.8). One hundred thirty-one foci dissected. sensitivity, specificity, predictive value, negative FDG-PET/CT detecting nodal metastases 84% (16/19), 65% (15/23), 66% (16/24), 83% (15/18), 74% (31/42) on per-patient basis, respectively. Mediastinal staging is insufficient due high false-positive rates presence pneumoconiosis. In an invasive technique such as mediastinoscopy seems mandatory for confirmation ipsilateral or contralateral metastasis.
