The Role of 18F-FDG PET/CT in Patients with Suspected Recurrent or Metastatic I-131 Negative Papillary Thyroid Cancer

Öz

We aimed to determine the role of 18F-fluoro-deoxy-glucose positron-emission tomography/computed tomography (18F-FDG-PET/CT) in papillary thyroid cancer (PTC) patients with high thyroglobulin (Tg) levels whose whole-body radioiodine scans (WBIS) or radiological methods fail to show the recurrent/metastatic sites. We evaluated 28 PTC patients retrospectively who had undergone PET/CT scans between January 2008-June 2011 in our department. Focal increased 18F-FDG uptake with corresponding abnormal soft tissue lesion on CT was interpreted as pathologic and SUVmax was calculated. PET/CT results were compared with Tg levels, WBIS, radiological methods and histopathological results following surgery/biopsy. Relationship between PET/CT results and Tg levels and SUVmax were analyzed, statisti-cally. Of 28 PET/CT scans, 16 were true positive (TP), 7 were true negative, 4 were false positive (FP) and one was false negative. The sensitivity, specificity, accuracy, positive predictive value and negative predictive value of PET/CT in detecting recurrent/metastatic foci was 94.1%, 63.6%, 82.1%, 80%, 87.5%, respectively. No statistically significant difference was found between Tg levels of PET/CT positive and negative groups. There was statistically significant difference in SUVmax (p=0.049) between TP and FP groups. 18F-FDG-PET/CT is a highly sensitive imaging method to detect suspected recurrence/metastases in PTC patients who have high Tg levels but negative WBIS.
