Notes
**Note 1:** Assign 88 for in situ cases (behavior code /2). TNM does not include an in situ category for GIST esophagus tumors. **Note 2:** Ignore intraluminal extension to adjacent segment(s) of colon; code depth of invasion or extra-appendiceal spread as indicated. **Note 3:** Tumor size must be known to assign T. You may use a physician’s statement of the T category if this is the only information in the medical record. * If no size or category is specified, assign TX **Note 4:** Assign the appropriate T category based on the tumor size for the following descriptions Tumor confined to muscular wall Tumor invades through submucosa and muscularis mucosae to involve with mucosa Localized, NOS Adventitia and/or soft tissue invaded Esophagus described as fixed Invasion into adventitia with invasion of/through mucosa Invasion of adjacent structures **Cervical esophagus (C150)** Carina Carotid artery Cervical vertebra€ Hypopharynx Jugular vein Larynx Thyroid gland Subclavian artery Trachea **Lower thoracic (abdominal) esophagus (C152, C155)** Diaphragm fixed **Upper thoracic esophagus (C151, C153)** Blood vessel(s), major: Aorta Azygos vein Pulmonary artery/vein Vena cava Diaphragm Main stem bronchus Trachea **Intrathoracic esophagus, upper (C153) or middle (C154)** Blood vessel(s), major: Aorta Gastric artery/vein Vena cava PericardiumNAACCR Item
