This input is used for staging
Notes
**Note 1:** Retroperitoneal sarcomas 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 Tumor confined to site of origin Adjacent connective tissue Adjacent organs/structures Adrenal(s) (suprarenal gland(s)) Aorta Ascending colon Bone/cartilage Descending colon Kidney(s) Pancreas Vena cava Vertebra Further contiguous extension, including: Extension to colon other than ascending or descending Localized, NOSNAACCR Item
