"notes" : "**Note 1:** Code only regional nodes and nodes, NOS, in this field. Distant nodes are coded in M (distant metastasis).\n\n**Note 2:** Regional lymph nodes for any part of the esophagus fall in the range from periesophageal/cervical to the celiac region. Contralateral and bilateral cervical, supraclavicular, and mediastinal lymph nodes are included.\n\n**Note 3:** Celiac nodes are coded in N (regional lymph nodes) for lower thoracic (abdominal) esophagus; they are coded in M (distant metastasis) for cervical and intrathoracic (upper and middle) esophagus. Cervical nodes, NOS are coded in N (regional lymph nodes) for cervical esophagus; they are coded in M (distant metastasis) for upper and lower thoracic (abdominal) esophagus.\n\n**Note 4:** Regional lymph node involvement is rare for GISTs, so that cases in which the nodal status is not associated clinically are classified as cN0 instead of cNX.\n\n**Note 5:** Lymph node stations/groups are listed in parentheses when applicable. \n\n**Regional Lymph Nodes for Esophagus (including contralateral or bilateral)** \n\n**All esophagus subsites**\n\n Anterior mediastinal (6)\n Mediastinal, NOS\n Peri-/paraesophageal (8L, 8M)\n\n**Cervical esophagus (C150)**\n\n Anterior deep cervical (laterotracheal) (recurrent laryngeal)\n Anterior mediastinal (6)\n Aortopulmonary (5)\n Cervical, NOS \n Cervical (deep), NOS\n Diaphragmatic (15)\n Internal jugular, NOS\n Jugulodigastric (subdigastric)\n Mediastinal, NOS\n Para-aortic (ascending aorta or phrenic)\n Paratracheal (2R, 2L, 4R, 4L)\n Posterior mediastinal (3P)\n Pulmonary ligament (9)\n Scalene (inferior deep cervical) (1)\n Subaortic\n Supraclavicular (transverse cervical) (1) \n Superior mediastinal\n \n**Upper thoracic esophagus (C151, C153)**\n\n Cervical lymph nodes\n\n**Lower thoracic (abdominal) esophagus (C152, C155)**\n\n Aortopulmonary (5)\n Diaphragmatic (15)\n Celiac lymph nodes (20)\n Left gastric (superior gastric) (17): cardiac (cardial), lesser curvature, perigastric, NOS\n Para-aortic (ascending aorta or phrenic)\n Paratracheal (2R, 2L, 4R, 4L)\n Posterior mediastinal (3P) (tracheoesophageal)\n Pulmonary ligament (9)\n Subaortic \n Superior mediastinal\n \n**Intrathoracic esophagus, upper (C153) or middle (C154)**\n\n Aortopulmonary (5)\n Carinal (tracheobronchial) (10R,10L) (tracheal bifurcation)\n Cervical: deep (NOS), lower (NOS), middle (NOS), upper (NOS)\n Diaphragmatic (15)\n Hilar (bronchopulmonary) (proximal lobar) (pulmonary root)\n Internal jugular, NOS\n Intrabronchial, NOS\n Jugulo-omohyoid (supraomohyoid)\n Jugulodigastric (subdigastric)\n Left gastric (superior gastric) (17): cardiac (cardial), lesser curvature, perigastric (NOS)\n Para-aortic (ascending aorta or phrenic)\n Peritracheal\n Posterior mediastinal (tracheoesophageal) \n Pulmonary ligament (9) \n Superior mediastinal",
