Abstract
Objective:To retrospectively the evaluate whole body PET/CT in detecting the primary tumors in cervical lymph node metastatic carcinoma. Methods: A total of 39 cervical lymph node metastatic carcinoma patients were included, and the diagnostic results of 18F-FDG PET/CT and traditional imaging were analyzed and compared with histopathological diagnosis or clinical follow-up data retrospectively. The diagnostic sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were calculated, respectively. The qualitative diagnosis using the maximal standard uptake value (SUVmax) was determined. Results: In all 39 patients, the sensitivity, specificity ,PPV and NPV of 18F-FDG PET/CT and traditional imaging was 82.1%, 81.8%, 92.0%, 64.3%and 57.1%, 45.4%, 72.7%, 29.4%.The sensitivity, specificity and accuracy of PET/CT were high than those of traditional imaging. 18F-FDG PET/CT detected more lymph node metastatic carcinoma and other organization metastatic carcinoma. Conclusion: PET/CT may be of relatively higher sensitivity, specificity, accuracy rate, PPV and NPV in identifying the primary tumor of cervical lymph node metastatic carcinoma. Traditional imaging detected better hollow organs than PET/CT, such as metastatic carcinoma of digestive system and urinary system. The two methods both have their advantages, and can’t replace each other. In clinical work, we should choose or combine them according to the patient’s specific circumstances, in order to better play to their advantage.关键词
