Overview
Staging
Definitions of TNM
The American Joint Committee on Cancer (AJCC) has designated staging by TNM classification to define neuroendocrine tumors
Neuroendocrine Tumors: Stomach
Neuroendocrine Tumors: Colon or Rectum
| T | Primary tumor |
|---|---|
| TX | Primary tumor cannot be assessed |
| T0 | No evidence of primary tumor |
| T1 | Tumor invades lamina propria or submucosa and size ≤2 cm |
| T1a | Tumor size <1 cm in greatest dimension |
| T1b | Tumor size 1–2 cm in greatest dimension |
| T2 | Tumor invades muscularis propria or size >2 cm with invasion of lamina propria or submucosa |
| T3 | Tumor invades through the muscularis propria into the subserosa or into nonperitonealized pericolic or perirectal tissues |
| T4 | Tumor invades peritoneum or other organs |
| For any T, add (m) for multiple tumors |
| 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 metastases |
| M1 | Distant metastasis |
