- W2890718045 abstract "Abstract Background The regional lymph nodes metastasis plays a crucial role in treatment strategies selection. Nowadays, computed tomography (CT) scan and endoscopic ultrasound (EUS) were main examination techniques to assess the regional lymph nodes metastasis. PET/CT metabolic parameters correlated to the lymph node metastasis, but the value of the prediction of lymph node metastasis need to be confirmed in additional studies. Methods 82 esophageal cancer patients that were pathologically confirmed and received initial treatment in our hospital from October 2011 to September 2016 were retrospectively analyzed. All patients underwent systemic 18F-FDG PET/CT examination within two weeks before operation. The metabolic parameters of primary lesions and postoperative pathological lymph node metastasis of esophageal cancer patients were recorded. The correlation between lymph node metastasis and metabolic parameters of primary lesion of esophageal cancer were analyzed by ROC curve and logistic binary regression. Results 1. The correlation between metabolic parameters of primary lesion (including SUVmax, SUVmean, MTV, TLG, HF) and lymph node metastasis were analyzed by ROC curve and logistic binary regression. Results showed that the P value obtained from the two methods was less than 0.05, suggesting that there was correlation between metabolic parameters of primary lesion and lymph node metastasis of esophageal cancer. 2. Multivariate analysis showed that only TLG had statistical significance, P = 0.027, suggesting that TLG of primary lesion had a certain diagnostic value for the lymph node metastasis of esophageal cancer. 3. ROC curve analysis showed that, the area under the curve (AUC) was 0.722 when TLG > 24.08, P = 0.001, suggesting that the minimum TLG of lymph node metastasis of esophageal cancer was 24.08. In addition, the thoracic esophageal cancers at the upper and middle segment were statistically significant. When TLG > 23.06, its AUC was 0.755, P = 0.001, suggesting that the minimum TLG was 23.06. Conclusion 18FDG-PET/CT metabolic parameters (SUVmax, SUVmean, MTV, TLG, HF) is closely related to lymph node metastasis of esophageal cancer. The TLG has a certain diagnostic value for the lymph node metastasis of esophageal cancer. Disclosure All authors have declared no conflicts of interest." @default.
