Overview
Staging
The AJCC has designated staging by TNM classification to define cancer of the esophagus and esophagogastric junction
Primary Tumor
- TX:Primary tumor cannot be assessed
- T0:No evidence of primary tumor
- Tis:High-grade dysplasia
- T1:Tumor invades lamina propria, muscularis mucosae, or submucosa
- T1a:Tumor invades lamina propria or muscularis mucosae
- T1b:Tumor invades submucosa
- T2:Tumor invades muscularis propria
- T3:Tumor invades adventitia
- T4:Tumor invades adjacent structures
- T4a:Resectable tumor invading pleura, pericardium, or diaphragm
- T4b:Unresectable tumor invading other adjacent structures, such as aorta, vertebral body, trachea, etc.
Regional Lymph Nodes (N)
- NX:Regional lymph nodes cannot be assessed
- N0:No regional lymph node metastasis
- N1:Metastases in 1–2 regional lymph nodes
- N2:Metastases in 3–6 regional lymph nodes
- N3:Metastases in ≥7 regional lymph nodes
Distant Metastasis (M)
- M0:No distant metastasis.
- M1:Distant metastasis
