Notes
**Note 1:** Code only regional nodes and nodes, NOS, in this field. Distant nodes are coded in M (distant metastasis). **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. **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. **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. **Note 5:** Lymph node stations/groups are listed in parentheses when applicable. **Regional Lymph Nodes for Esophagus (including contralateral or bilateral)** **All esophagus subsites** Anterior mediastinal (6) Mediastinal, NOS Peri-/paraesophageal (8L, 8M) **Cervical esophagus (C150)** Anterior deep cervical (laterotracheal) (recurrent laryngeal) Anterior mediastinal (6) Aortopulmonary (5) Cervical, NOS Cervical (deep), NOS Diaphragmatic (15) Internal jugular, NOS Jugulodigastric (subdigastric) Mediastinal, NOS Para-aortic (ascending aorta or phrenic) Paratracheal (2R, 2L, 4R, 4L) Posterior mediastinal (3P) Pulmonary ligament (9) Scalene (inferior deep cervical) (1) Subaortic Supraclavicular (transverse cervical) (1) Superior mediastinal **Upper thoracic esophagus (C151, C153)** Cervical lymph nodes **Lower thoracic (abdominal) esophagus (C152, C155)** Aortopulmonary (5) Diaphragmatic (15) Celiac lymph nodes (20) Left gastric (superior gastric) (17): cardiac (cardial), lesser curvature, perigastric, NOS Para-aortic (ascending aorta or phrenic) Paratracheal (2R, 2L, 4R, 4L) Posterior mediastinal (3P) (tracheoesophageal) Pulmonary ligament (9) Subaortic Superior mediastinal **Intrathoracic esophagus, upper (C153) or middle (C154)** Aortopulmonary (5) Carinal (tracheobronchial) (10R,10L) (tracheal bifurcation) Cervical: deep (NOS), lower (NOS), middle (NOS), upper (NOS) Diaphragmatic (15) Hilar (bronchopulmonary) (proximal lobar) (pulmonary root) Internal jugular, NOS Intrabronchial, NOS Jugulo-omohyoid (supraomohyoid) Jugulodigastric (subdigastric) Left gastric (superior gastric) (17): cardiac (cardial), lesser curvature, perigastric (NOS) Para-aortic (ascending aorta or phrenic) Peritracheal Posterior mediastinal (tracheoesophageal) Pulmonary ligament (9) Superior mediastinalNAACCR Item
