Abstract:

Objective

To explore the value of 18-fluorine flurodeoxyglucose (18F-FDG) positron-emission tomography (PET)/computed tomography (CT) in detecting recurrence and metastasis in postoperative colorectal cancer patients with elevated serum carcinoembryonic antigen (CEA).

Methods

Clinical data of 60 cases of colorectal cancer, including PET/CT, pathological, and follow-up results, were analyzed retrospectively.

Results

There were 50 18F-FDG PET/CT positive and 10 18F-FDG PET/CT negative cases, including 1 false positive and 3 false negative cases. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of 18F-FDG PET/CT in detecting recurrence and metastasis in postoperative colorectal cancer patients with elevated serum CEA were 94.2%(49/52), 87.5% (7/8), 98.0% (49/50), 70.0% (7/10), and 93.3% (56/60), respectively.

Conclusion

18F-FDG PET/CT has high clinical value in postoperative colorectal cancer patients with elevated serum CEA, and it has a high sensitivity, specificity, and accuracy in the detection of recurrence and metastasis.
