Abstract
Objective
To evaluate the accuracy of integrated FDG-PET/CT and tumor markers for the depiction of recurrent ovarian carcinoma.
Methods
Patients with pathologically proven ovarian cancer, who underwent cytoreductive surgery and 3–6 cycles of adjuvant chemotherapy, were included in this study. They all underwent a thorough physical examination, tumor marker determination, and FDG-PET/CT imaging. The sensitivity, specificity, accuracy, and positive and negative predictive values for the tumor detection with PET/CT versus different tumor markers were performed in relation to the results at histological analysis after second-look surgery or clinical follow-up.
Results
A total of 37 patients underwent FDG-PET/CT scans. Among them, 22 patients underwent exploratory laparotomy and 15 had diagnostic laparoscopy. Overall, 24 patients were documented to have ovarian cancer recurrence after second operation. FDG-PET/CT had sensitivity, specificity, accuracy, and positive and negative predictive values of 100, 85, 94, 92, and 100%, respectively.
Conclusion
Our study has shown that PET/CT is a sensitive tool to assist in the early identification and recurrent ovarian cancer, amenable to secondary cytoreduction.
