 Accurate pre-treatment staging, particularly with regard to the depth of tumor invasion, lymph node involvement, and distant metastases, is vital in determining the most appropriate procedures for the management of esophageal carcinomas. In particular, lymph node staging is an important independent prognostic indicator in esophageal cancer and has a major impact on treatment selection. Conventional anatomical imaging procedures, including computed tomography (CT) and magnetic resonance imaging (MRI), have been available for the pre-treatment staging of esophageal cancer. The imaging methods that rely on detection of the structural changes caused by tumors are inaccurate in determining the extent of esophageal cancer, especially lymph node metastasis. Recent studies have reported on the efficacy of 18F-fluorodeoxyglucose positron emission tomography (FDG-PET) for staging of esophageal carcinoma. FDG-PET imaging is noninvasive and provides qualitatively different information compared with CT imaging, due to its reliance on the metabolic function of tumors rather than tumor size alone. In the current article, we review the performance of main imaging methods in the assessment of lymph node staging of esophageal carcinoma.
