Fluorodeoxyglucose positron emission tomography in pulmonary carcinoid tumors.

摘要: Aim The role of fluorodeoxyglucose positron emission tomography (FDG-PET) as an additional investigation to computer for pulmonary carcinoid tumors remains controversial. aim this study was assess the FDG-PET diagnosis and staging tumors. Methods We performed a retrospective mono-institutional analysis data from 97 patients with pathologically confirmed tumor who had been operated on between July 1998 April 2009 preoperative scan performed. Results Sixty-five (67%) were typical (TC) 32 (33%) atypical (AC) Overall sensitivity 67% being lower TC (60%) than AC (81%) (P=0.04). negative smaller positive tumors, respective median size 15 17 mm (P=0.02). Median SUVmax FDG-PET-positive 4.0 (2.8-5.1) no difference Ki-67 expression respectively 4.7% 3.1% (P=0.05). During follow-up 49 months (interquartile range 30-63 months), 9 (4TC, 5AC) developed recurrent disease. Neither nor resulted associated disease-free survival. Conclusion With overall 67%, has shown be useful in work-up suspect lung In particular it could have larger These results warrant prospective evaluation tumor.
