Pathologic T
This input is used for staging
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

|---|---|---|---|
| pX | pTX | Primary tumor cannot be assessed | Pathologic classification criteria met, evaluation done: Physician unable to assess T Surgical resection of primary tumor, extension not stated Tumor size (TS) unknown for T categories where TS needed to determine T Physician assigns pTX, no other information available to determine T |
| p0 | pT0 | No evidence of primary tumor | |
| p1 | pT1 | Tumor 2 cm or less in greatest dimension | Stated as T1 |
| p2 | pT2 | Tumor more than 2 cm but not more than 5 cm in greatest dimension | Stated as T2 |
| p3 | pT3 | Tumor more than 5 cm but not more than 10 cm in greatest dimension | Stated as T3 |
| p4 | pT4 | Tumor more than 10 cm in greatest dimension | Stated as T4 |
| 88 | 88 | Not applicable | In situ case but no pTis is defined by TNM Death certificate only (DCO) case |
| <BLANK> | BLANK | See Registrar Notes | Pathologic classification criteria not met Pathologic classification criteria met, evaluation done: Results not documented in patient record No surgical resection of known primary tumor (not T0) Resection insufficient for site-specific pathologic assessment No surgical resection of primary tumor and there isn’t a positive biopsy of a structure in the highest T category and highest N category Evidence of metastatic disease (pM1), no other workup Only Pathologic Stage Group documented (no T, N, or M information available) |
