Collaborative Stage for TNM 7 - Revised 08/18/2010 [ Schema ]
| Code | Description | Staging Basis |
| 0 | Does not meet criteria for AJCC pathologic staging: No regional lymph nodes, satellite nodule(s) or in-transit metastases (nodules) removed for examination. Evidence based on physical examination, imaging examination, or other non-invasive clinical evidence. No autopsy evidence used. | c |
| 1 | Does not meet criteria for AJCC pathologic staging: No regional lymph nodes, satellite nodule(s) or in-transit metastases (nodules) removed for examination. Evidence based on endoscopic examination, diagnostic biopsy including fine needle aspiration of lymph node(s), satellite nodule(s) or in-transit metastases (nodules) or other invasive techniques, including surgical observation without biopsy. No autopsy evidence used. | c |
| 2 | Meets criteria for AJCC pathologic staging: No regional lymph nodes, satellite nodule(s) or in-transit metastases (nodules) removed for examination, but evidence derived from autopsy (tumor was suspected or diagnosed prior to autopsy). | p |
| 3 | Meets criteria for AJCC pathologic staging: Regional lymph nodes, satellite nodule(s) or in-transit metastases (nodules) removed for examination (removal of at least one lymph node, satellite nodule(s) or in-transit metastasis) WITHOUT pre-surgical systemic treatment or radiation OR lymph nodes, satellite nodule(s) or in-transit metastases (nodules) removed for examination, unknown if pre-surgical systemic treatment or radiation performed. | p |
| 5 | Does not meet criteria for AJCC y-pathologic (yp) staging: Regional lymph nodes, satellite nodule(s) or in-transit metastases (nodules) removed for examination AFTER neoadjuvant therapy, AND lymph node, satellite nodule(s) or in-transit metastases (nodules) evaluation based on clinical evidence, unless the pathologic evidence at surgery (AFTER neoadjuvant) is more extensive (see code 6). | c |
| 6 | Meets criteria for AJCC y-pathologic (yp) staging: Regional lymph nodes, satellite nodule(s) or in-transit metastases (nodules) removed for examination AFTER neoadjuvant therapy, AND lymph node(s), satellite nodule(s) or in-transit metastases (nodules) evaluation based on pathological evidence, because pathologic evidence at surgery is more extensive than clinical evidence before treatment. | yp |
| 8 | Meets criteria for AJCC autopsy (a) staging: Evidence from autopsy; tumor was unsuspected or undiagnosed prior to autopsy. | a |
| 9 | Unknown if lymph nodes, satellite nodule(s) or in-transit metastases (nodules ) removed for examination Not assessed; cannot be assessed Unknown if assessed Not documented in patient record | c |
