Evaluation of ~(18)F-FDG PET/CT imaging for gastric cancer

Objective To outline the values of 18 F-FDG PET/CT imaging in evaluating gastric cancer. Methods 51 patients proven with gastric cancer by gastroscope and histopathoogical examination were involved in this study.All patients received 18 F-FDG PET/CT scanning,the tumor typing,staging,and metastasis were obtained,and compared to the outcomes of surgical findings and post-operative pathological findings. Results Among 51 patients with gastric cancer, 43 of them were found with primary gastric cancer in PET scanner, with a sensitivity of 84.32%(43/51);18 F-FDG PET/CT presented all patients with gastric cancer,with a sensitivity 100.00%(51/51);PET/CT scanned for locally lymphatic metastasis resulting in a sensitivity of 94.29%(33/35);18 F-FDG PET/CT scanned for distal tissues or organs metastasis resulting in a sensitivity of 86.67%(13/15).Conclusion 18F-FDG PET/CT imaging is sensitive in scanning primary gastric cance,and locally lymphatic metastasis and distal tissues or organs metastasis.It is valuable of preoperative typing for gastric cancer.
