18F-FDG PET/CT、CA19-9对胰腺癌的诊断价值
Diagnostic value of 18F-FDG PET/CT and CA19-9 in pancreatic cancer
摘要
Abstract
Objective To discuss the diagnostic value of 18 F-fluorodeoxyglucose(18 F-FDG) PET/CT and CA19-9 in pancreatic cancer. Methods 55 patients with space-occupying lesions of the pancreas confirmed by B ultrasound,CT or MRI were selected for this study. Whole body 18 F-FDG PET/CT scanning was performed and the level of serum CA19-9 was measured. Results Among 55 patients with space-occupying pancreatic lesions,35 patients were diagnosed as pancreatic cancers, and other 20 patients as benign diseases. The values of mean SUV and CA19-9 were significantly different between pancreatic cancers and benign diseases(t= 3. 543 ,P = 0. 001 ,t = 2. 211 , P = 0. 034 ) respectively. The sensitivity, specificity, positive and negative predictive value, accuracy of is FDG PET/CT was, respectively, 97. 1 % ,80. 0 % , 89. 5% , 94. 1 % and 90. 9 %. The diagnostic value of CA19-9 was lower than that of 18 F-FDG PFT/CT, while combined application the diagnosis specificity increased to 90. 0% , with only a slight decreasing in diag nosis accuracy(87. 3%). Conclusion 18 F-FDG PET/CT has high sensitivity in diagnosis of pancreatic cancer and relative specificity,whtch would increase the diagnosis specificity combined with CA19-9.关键词
