Figure 11a. Axial diagrams show the regional drainage pathways (black nodes) for esophageal cancer. Supraclavicular nodes are considered regional nodes (N1) for tumors that originate at the cervical esophagus but represent distant disease (M1) for intrathoracic esophageal tumors. E = esophagus. (a) Diagram shows the anterior scalene/supraclavicular nodes (ASSCN) and periesophageal/posterior mediastinum nodes (PEPMN). ASM = anterior scalene muscle, LCCA = left common carotid artery, LJV = left internal jugular vein, RCCA = right common carotid artery, RJV = right internal jugular vein, Tr = trachea. (b) Diagram shows the periesophageal/posterior mediastinum nodes (PEPMN) and right paratracheal nodes (RPTN). AA = aortic arch, LBCV = left brachiocephalic vein, RBCV = right brachiocephalic vein, TD = thoracic duct, Tr = trachea. (c) Diagram shows the periesophageal/posterior mediastinum nodes (PEPMN) and subcarinal node (SCN). AA = ascending aorta, Ao = aorta, LMB = left main bronchus, PA = pulmonary artery, RMB = right main bronchus, RPA = right pulmonary artery, SVC = superior vena cava, TD = thoracic duct. (d) Diagram shows the gastrohepatic ligament/celiac nodes (GHLCN) and periesophageal/posterior mediastinum nodes (PEPMN). Ao = aorta, TD = thoracic duct.
