Cím:Az FDG-PET-vizsgálat értéke a pancreascarcinoma diagnosztikájában = The role of FDG-PET scan in the diagnosis of pancreatic carcinoma / Papós Miklós, Takács Tamás, Pávics László, Farkas Gyula, Ambrus Edit, Szakáll Szabolcs jr., Lonovics János, Csernay László, Trón Lajos

Megjegyzések:In 22 patients with focal pancreatic lesions, the values of different diagnostic modalities were analysed for the evaluation of malignancy. The CA 19-9 level was elevated in 4/5 malignant cases (sensitivity: 80 per cent) and in 4/15 of benign cases specificity: 73 per cent). Hypodensity/hypoechogeneity was considered to be the characteristic sign of malignancy during CT/ultrasound (sensitivity: 100 per cent, specificity: 50 per cent / 47 per cent). ERCP was found to be specific but not sensitive enough and the rate of unsuccessful investigations was relatively high (4/22). The diagnostic value of FDG-PET was found to be superior to other diagnostic modalities (sensitivity 100 per cent, specificity 88 per cent). In cases with focal pancreatic hypoechogenic/hypodense lesions detected by CT or US in suspicion of malignancy, the FDG-PET should be the next step in the diagnostic strategy.

Cím:The possible role of F-18 FDG positron emission tomography in the differential diagnosis of focal pancreatic lesions / Papós Miklós, Takács Tamás, Trón Lajos, Farkas Gyula, Ambrus Edit, Szakáll Szabolcs, Lonovics János, Csernay László, Pávics László

Megjegyzések:To compare the diagnostic values of different methods for the differentiation of malignant from benign pancreatic lesions. METHODS: In 22 patients with focal pancreatic lesions, the carbohydrate antigen (CA) 19-9 level was measured; abdominal ultrasound (US), computed tomography (CT), endoscopic retrograde cholangiopancreatography (ERCP), and F-18 fluorodeoxyglucose (FDG) positron emission tomography (PET) were performed; and the value of these methods were analyzed for their use in cancer diagnosis. RESULTS: Malignant lesions were identified in six patients and verified by surgery or clinical follow-up. The CA 19-9 level was elevated in four of the five patients examined (sensitivity, 80%). In all six cases, US and CT revealed hypoechogenic and hypodense areas (sensitivity, 100%). In one patient, ERCP was unsuccessful but yielded true-positive results in three others (sensitivity, 60%). The sensitivity of FDG PET was 100%. Sixteen focal cases of pancreatic disease proved to be benign. The CA 19-9 level was elevated in four of them (specificity, 73%). Hypoechogenic and hypodense areas were evident on US and CT in eight patients. The specificity of CT was 50% (8 of 16 cases). The specificity of US was 47% (7 of 15 cases). The specificity of successful ERCP was 92%. Fourteen negative FDG-PET results were truly negative. In two patients, however, the PET findings proved to be falsely positive (specificity, 88%). CONCLUSIONS: FDG-PET is an effective tool to differentiate malignant from benign focal pancreatic lesions. In persons with focal pancreatic hypoechogenic or hypodense lesions detected by CT or US and an elevated CA 19-9 level, FDG PET should be the next step in the diagnostic strategy.
