Pathologic T

This input is used for staging


**Note 1:** For TNM staging, sarcomas of the heart and mediastinum are classified as deep tumors.Only T1b or T2b are available. **Note 2:** 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 3:** Assign the appropriate T category based on the tumor size for the following descriptions Invasive tumor confined to site of origin Adjacent connective tissue For heart (C380) Visceral pericardium (epicardium) Adjacent organs/structures For heart (C380) Ascending aorta Parietal pericardium Vena cava For mediastinum (C381-C383, C388) Descending aorta Esophagus Large (named) artery(ies) Large (named) vein(s) Pericardium, NOS Parietal Visceral (epicardium) Phrenic nerve(s) Pleura, NOS Parietal pleura Visceral pleura of lung Sternum Sympathetic nerve trunk(s) Thoracic duct Thymus Trachea, parietal pleura Vertebra(e) Further contiguous extension Localized, NOS
