TNM Classification
| T | Primary Tumor |
|---|---|
| Tx | Primary tumor cannot be assessed |
| T0 | No evidence of primary tumor |
| Tis | Carcinoma in situ |
| T1 | Tumor limited to the pancreas, ≤2 cm in greatest dimension |
| T2 | Tumor limited to the pancreas, >2 cm in greatest dimension |
| T3 | Tumor extends beyond the pancreas but without involvement of the celiac axis or the superior mesenteric artery |
| T4 | Tumor involves the celiac axis or the superior mesenteric artery (unresectable primary tumor) |
| N | Regional Lymph Nodes |
|---|---|
| NX | Regional lymph nodes cannot be assessed |
| N0 | No regional lymph node metastasis |
| N1 | Regional lymph node metastasis |
| M | Distant Metastases |
|---|---|
| M0 | No distant metastasis |
| M1 | Distant metastasis |
Anatomic Stage/Prognostic Groups
| Stage | T | N | M |
|---|---|---|---|
| 0 | Tis | N0 | M0 |
| IA | T1 | N0 | M0 |
| IB | T2 | N0 | M0 |
| IIA | T3 | N0 | M0 |
| IIB | T1 | N1 | M0 |
| T2 | N1 | M0 | |
| T3 | N1 | M0 | |
| III | T4 | Any N | M0 |
| IV | Any T | Any N | M1 |
