ABSTRACT
Objective To determine the value of 18F-FDG PET-CT in detecting the primary origin of cancer of unknown primary (CUP).Methods A total of 48 patients (age range 41-82 years,mean age of 57±16 years, 20 females) were retrospectively selected. All patients were diagnosed as CUP and were examined by 18F-FDG PET-CT scan.The patients were divided into cervical lymph node metastasis group (28 cases) and extra-cervical lymph node metastasis group (20 cases) according to different metastasis site.Sensitivity of 18F-FDG PET-CT to detect primary tumor site was compared between these two groups.Results 18F-FDG PET-CT detected primary tumors in 32 of 48 patients (66.7 %), the cervical lymph node metastasis tumors in 22 of 28 patients (78.6 %), and extra-cervical lymph node metastasis tumors in 10 of 20 patients (50.0 %).There was significant difference between cervical lymph node metastasis group and extra-cervical lymph node metastasis group (x2 =4.286,P < 0.05).Conclusion 18F-FDG PET-CT has a high sensitivity to detect primary origin of CUP,especially for patients with cervical lymph node metastasis.
