Improved detection of metastatic lymph nodes in oesophageal squamous cell carcinoma by combined interpretation of fluorine-18-fluorodeoxyglucose positron-emission tomography/computed tomography

We sought to evaluate the diagnostic performance of fluorine-18-fluorodeoxyglucose positron-emission tomography/computed tomography (18F-FDG PET/CT) in the detection of metastatic lymph nodes by combined interpre...

This study evaluated the utility of pretreatment maximal esophageal wall thickness on CT scans to predict treatment outcomes after CRT in patients with locally advanced ESCC.MethodsEighty-one patients with T3 locally advanced ESCC, whom were treated completely with CRT with and without surgery, and had available CT scans before and after CRT at a university hospital between 2005 and 2015, were retrospectively reviewed.ResultTwenty patients (24.7%) had esophagectomy after neoadjuvant CRT and sixty-one patients (75.3%) had definitive CRT. The maximal esophageal wall thicknesses were measured retrospectively and correlated wi...

CONCLUSIONS: We conclude that high levels of intratumoral F. nucleatum have a prognostic significance for predicting poor RFS in ESCC patients. More importantly, our data indicates that higher F. nucleatum burden correlates with poor response to neoadjuvant chemotherapy, suggesting the possibility that an antibiotic intervention against this bacterium may significantly improve therapeutic response in ESCC patients.

220Objectives: To evaluate the diagnostic performance of 18F-FDG PET/CT in detecting individual lymph node metastasis using Hounsfield units of lymph nodes on non-contrast CT image component and 18F-FDG uptake in patients with esophageal squamous cell carcinoma. Methods: 203 patients with esophageal squamous cell carcinoma underwent 18F-FDG PET/CT before esophagectomy and lymph node dissection. Maximum standardized uptake value (SUVmax), mean Hounsfield unit (HU), and short axis diameters (size) were evaluated on non-contrast CT and PET images of PET/CT scan. The images were analyzed by three methods. In Method 1, nodal st...

Conclusions: To cover 94.5% of ESCC subclinical lesions in the CTVp, a 3-cm margin along the cranial-caudal axis should be added to the primary gross tumor volume as defined by FDG-PET/CT, as well as a cutoff SUVmax value of 2.5. Although preoperative FDG PET/CT images may not reveal lesions directly, the SUVmax and MTV measurements together could predict their presence. Background Esophageal carcinoma often occurs as squamous cell carcinoma (ESCC), a highly aggressive malignancy with a poor prognosis worldwide. The incidence rates of ESCC are particularly high in China (1). Most patients with ESCC have locally adv...

Authors: D'Journo XB Abstract Epidemiology of esophageal cancer and esophagogastric junction (EGJ) has deeply changed for the past two decades with a dramatically increase of adenocarcinoma whereas squamous cell carcinoma (SCC) has slowly decreased. Moreover, the two histological types differ in a number of features including risks factors, tumor location, tumor biology and outcomes. In acknowledgement of these differences, the newest 8th edition of the American Joint Committee on Cancer (AJCC) tumor, node and metastasis (TNM) staging classification of epithelial cancers of the esophagus and EGJ has refined this hi...

CONCLUSION: EICT combined with GSI assist allows differential diagnosis between the T1/2 and T3 stages. The ability to differentially diagnose the T3 and T4 stages of medullary ESCC can be improved by quantitatively and qualitatively analyzing the adipose tissue in front of the vertebral body.

Conclusion: It is important to note that all patients with FDG-avid primary tumor in the no-CRT group developed local recurrence. This would suggest that concurrent chemotherapy is an integral part of disease management in patients with T1 esophageal squamous cell carcinoma.
