- W2034781949 abstract "Purpose The role of 18F-FDG PET has been studied in ovarian carcinoma, but its sensitivity and specificity calculations are based on dedicated PET acquisition, not PET/CT in the majority of the published studies. Therefore, we were prompted to review our experience with PET/CT in the management of patients with ovarian carcinoma. Materials and methods This is a retrospective study of 43 women with ovarian carcinoma, 27–80 years old (average: 53.9±7.8), who had whole-body PET/CT at our institution from 1 January 2003 to 31 August 2006. We reviewed the patients' outcomes from medical records and compared them to the interpretation of the PET/CT scans. Sensitivity and specificity were calculated using a 2×2 table with pathology results (79.1% of the patients) or clinical follow-up (20.9% of the cases) as the ‘gold standard’. Confidence interval (CI) estimations were performed using the Wilson score method. Results All patients had advanced stage ovarian cancer and the study was requested for re-staging. A total of 60 scans were performed: 30 patients had one scan, nine patients had two scans and four patients had three scans. The administered doses of 18F-FDG ranged from 381.1 to 769.6 MBq (average: 569.8±73.3). PET/CT had a sensitivity of 88.4% (95% CI: 75.1–95.4) and a specificity of 88.2% (95% CI: 64.4–97.9) for detection of ovarian cancer. The SUV max of the detected lesions ranged from 3 to 27 (average: 9.4±5.9). The CA-125 tumor marker ranged from 3 to 935 kU/ml (average: 265.2) in patients with positive scans and 4–139 kU/ml (average: 17.1) in patients with negative scans. This difference was statistically significant (P value: 0.0242). Conclusion This study confirms the good results of 18F-FDG PET/CT for identification of residual/recurrent ovarian cancer, as well as for distant metastases localization. PET/CT should be an integral part in evaluation of patients with high-risk ovarian cancer or rising values of tumor markers (CA-125), prior to selection of the most appropriate therapy." @default.
