RESUMEN
Objective: To evaluate the clinical value of 18F-FDG PET/CT in diagnosing the recurrence or metastasis of the postoperative patients with gastrointestinal malignant tumor. Methods: Sixty-eight postoperative patients with gastrointestinal malignant tumor were studied with 18F-FDG PET/CT, and serum CEA and CA19-9 were assayed. Results: Thirty-seven patients were found to be recurrent or metastatic. The sensitivity and specificity of PET/CT detection were 97.3% and 96.8%,and the positive rates of PET/CT combined with CEA and CA19-9 were 100% and 97.8%.Conclusion: PET/CT has a higher sensitivity and specificity than tumor marker detection in assessment of recurrence and metastasis.
