Abstract
Background
Preoperative precise staging is essential for the treatment of gastric cancer (GC); however, the diagnostic accuracy of conventional modalities needs to be increased. The present study investigated the clinical value of positron emission tomography-computed tomography (PET-CT) for the staging of GC.
Methods
This was a retrospective study of 117 patients with a clinical diagnosis of advanced GC who underwent PET-CT followed by gastrectomy. The incidence of FDG uptake in the primary tumor or lymph nodes and its relationship with clinicopathological factors, particularly pathological stage (pStage) III/IV, were examined.
Results
FDG uptake in the primary tumor was noted in 83 patients (70.9%). FDG uptake in the lymph nodes was detected in 21 patients (17.9%), and its sensitivity and specificity for lymph node metastasis were 22.7 and 90.5%, respectively. Multiple logistic regression analyses showed that FDG uptake in the primary tumor (odds ratio (OR) 2.764; 95% confidence interval (CI) 1.104–7.459, p = 0.029) and that in the lymph nodes (OR 4.660; 95% CI 1.675–13.84, p = 0.003) were factors independently associated with pStage III/IV. FDG uptake in the primary tumor detected pStage III/IV with higher sensitivity (80.4%) and that in lymph nodes found pStage III/IV with higher specificity (88.7%) than those of upper endoscopy plus CT (60.9 and 67.6%, respectively).
Conclusions
PET-CT appears to be a useful complementary modality in the assessment of pStage III/IV because of the high sensitivity of FDG uptake in the primary tumor and the high specificity of FDG uptake in the lymph nodes.
