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
Primary Tumor (T)
- TX-Primary tumor cannot be assessed
- T0-No evidence of primary tumor
- Tis-Carcinoma in situ/dysplasia (tumor size <0.5 mm), confined to mucosa
- T1-Tumor invades lamina propria or submucosa and ≤1 cm in size
- T2-Tumor invades muscularis propria or >1 cm in size
- T3-Tumor penetrates subserosa
- T4-Tumor invades visceral peritoneum (serosal) or other organs or adjacent structures
- For any T, add (m) for multiple tumors
Regional Lymph Nodes (N)
- NX-Regional lymph nodes cannot be assessed
- N0-No regional lymph node metastasis
- N1-Regional lymph node metastasis
Distant Metastases (M)
- M0-No distant metastases
- M1-Distant metastasis
Neuroendocrine Tumors: Duodenum/Ampulla/Jejunum/Ileum
Primary Tumor (T)
- TX-Primary tumor cannot be assessed
- T0-No evidence of primary tumor
- T1-Tumor invades lamina propria or submucosa and size ≤1 cmb (small intestinal tumors); tumor ≤1 cm (ampullary tumors)
- T2-Tumor invades muscularis propria or size >1 cm (small intestinal tumors); tumor >1 cm (ampullary tumors)
- T3-Tumor invades through the muscularis propria into subserosal tissue without penetration of overlying serosa (jejunal or ileal tumors) or invades pancreas or retroperitoneum (ampullary or duodenal tumors) or into nonperitonealized tissue
- T4-Tumor invades visceral peritoneum (serosa) or invades other organs
- For any T, add (m) for multiple tumors
Neuroendocrine Tumors: Colon or Rectum
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. |
