Esophagus cancer staging helps to determine the disease prognosis and to select an appropriate treatment strategy.
TNM is the most commonly used staging system for breast cancer. “T” stands for “Tumor Size”, “N” for “Lymph Nodes”, and “M” for “Metastasis”. Numbers and/or letters after T (is, 1a, 1b, 2, and 3), N (0, 1, 2, and 3), and M (0 and 1) provide more details about each of these factors.

Before discussing the staging, we will understand the NORMAL ANATOMY OF ESOPHAGUS.
|Tis||Pre-cancerous or cancerous cells present only in the epithelium of esophagus|
|T1a||Tumor invades mucosa|
|T1b||Cancerous cells present in all layers of the esophagus epithelium and into the middle muscular layer|
|T2||Tumor invades the muscular layer (muscularis propria)|
|T3||Tumor invades in the serosa/adventitia|
|T4a||Tumor invades the pleura, pericardium, azygous vein, diaphragm , or peritoneum|
|T4b||Tumor invades other adjacent structures, such as aorta, vertebral body, or airway.|
|N0||No regional lymph node involvement|
|N1||Tumor has spread to 1 to 2 regional lymph nodes|
|N2||Tumor has spread to 3 to 6 regional lymph nodes|
|N3||Tumor has spread to 7 or more regional lymph nodes|
|M0||No spread to distant sites|
|M1||Spread to distant sites like lungs, pleura, peritoneum, liver, bones, etc|
