Clinical T
This input is used for staging
Notes
**Note 1:** Islets of Langerhans are distributed throughout the pancreas; an islet tumor is coded to the subsite of the pancreas in which the tumor arises if the information is available. **Note 2:** Islets of Langerhans are distributed throughout the pancreas. * An islet tumor is coded according to the subsite of the pancreas in which the tumor arises if the information is available **Note 3:** Tumor size must be known to assign a value of T1 or T2. You may use a physician’s statement of the T category if this is the only information in the medical record. * If the tumor appears to be in the T1 or T2 categories, but no size or category is specified, assign TX **Note 4:** Assign the appropriate T category (T1, T2) based on the tumor size for the following descriptions Confined to pancreas Localized, NOSNAACCR Item
NAACCR #940| Clinical T | Clinical T Display | Description | Registrar Notes |
|---|---|---|---|
| cX | cTX | Primary tumor cannot be assessed | Clinical classification criteria met, evaluation done: Physician unable to assess T Extension cannot be determined Tumor size (TS) unknown for T categories where TS needed to determine T Physician assigns cTX, no other information available to determine T |
| c0 | cT0 | No evidence of primary tumor | |
| pIS | pTis | Carcinoma in situ | In situ, intraepithelial, noninvasive Pancreatic Intraepithelial Neoplasia III (PanInIII) PanIN-III classification |
| c1 | cT1 | Tumor limited to pancreas, 2 cm or less in greatest dimension | Stated as T1 |
| c2 | cT2 | Tumor limited to pancreas, more than 2 cm in greatest dimension | Stated as T2 |
| c3 | cT3 | Tumor extends beyond pancreas, but WITHOUT involvement celiac axis or superior mesenteric artery |
Adjacent large vessel(s) Colon Spleen Stomach Ampulla of Vater Duodenum Extra hepatic bile duct(s) Peripancreatic tissue Stated as T3 |
| c4 | cT4 | Tumor involves celiac axis or superior mesenteric artery | Aorta Celiac artery Superior mesenteric artery Tumor is inseparable from the celiac axis or superior mesenteric artery Further contiguous extension Stated as T4 |
| 88 | 88 | Not applicable | Primary site/histology not TNM defined Death certificate only (DCO) case |
| <BLANK> | BLANK | See Registrar Notes | Clinical classification criteria not met Clinical classification criteria met, evaluation done: No information about diagnostic workup Results not documented in record Clinical evaluation of primary tumor not done or unknown if done Tumor first detected on surgical resection (no clinical workup) Evidence of metastatic disease [(cM1) or (pM1)], no other workup Only Clinical Stage Group documented (no T, N, or M information available) |
