Doctors sort cancerous growth by the staging method. They also classify cancer by its grade, which tells how many cancer cells look healthy.
With the method of esophageal cancer staging, you can find the cancer cells, their spread, and if they affect other body parts. Doctors can find the cancer stage with many diagnostic tests, so staging doesn’t finish until you complete all tests.
After they know about the cancer stage, the doctors suggest the best treatment, which helps the patient’s prognosis and recovery. There are a few types of esophageal cancer staging shown below.
The TNM Cancer Staging System
Doctors commonly say the cancer stage is the TNM system. Doctors use outcomes of diagnostic scans and tests to answer such questions:
Tumor (T): How deeply the main tumor grows into the esophagus wall and nearby tissue?
Node (N): Did the tumor move to the lymph nodes? If so, how much and where?
Metastasis (M): Did cancer spread to other body parts? If so, how much and where?
Esophageal cancer staging is a common way to find cancer, so doctors can work to plan the best treatments. They mix the outcomes to find the cancer stage for each patient.
Five stages are there for cancer: stage 0 (zero) and stages I through IV (1 through 4).
Doctors also categorize esophageal cancer staging with their grade (G). The grade is helpful to describe how many cancer cells appear like healthy cells when looking at a magnified specimen.
Doctors then compare the cancerous and healthy tissue. The healthy tissue has many cells grouped. When cancer appears similar to healthy tissue and has other cell groupings, we call it “differentiated.” When the cancerous tissue looks different from healthy ones, we call it “poorly differentiated.”
Grouping Of Cancer Stage
Doctors assign esophageal cancer staging after mixing the T, N, and M classifications. Many staging systems exist for the two most common esophageal cancer types: adenocarcinoma and squamous cell carcinoma. We’ve described the staging system for each one below.
Squamous Cell Esophagus Carcinoma Staging
For squamous cell carcinoma esophageal cancer staging, the stages are divided on whether the tumor is in the lower, middle, or upper esophagus part and the grade (G) of tumor cells.
The cancer is present only on the top esophagus lining.
The cancer is only on the top esophagus layers.
Cancer meets either of the below conditions for esophageal cancer staging:
- The cancer is in the top esophagus layers, but these cells are less differentiated.
- The tumor is in the third esophagus layer but didn’t spread to lymph nodes or other body parts.
For any of these conditions:
- The tumor is in the third esophagus layer. Cancer cells spread into it but not through the esophagus muscle wall.
- A tumor moves to the outer layer of the middle or upper esophagus part.
- The tumor is there in the outer layer or lower esophagus part.
Is for any of these esophageal cancer staging symptoms:
- A tumor is in the upper or middle part’s outer layer of the esophagus. The tumor cells are less differentiated.
- A tumor is there in the outer layer of any esophagus area.
- The tumor is there in any esophagus part, and cancer cells spread into the esophagus lining and inner layers. Cancers also spread to 1 to 2 lymph nodes near the tumor.
For any of such esophageal cancer staging conditions:
- The tumor is in any esophagus part, and cancer cells spread into the esophagus lining and underneath layers. The cancer cells also moved to 3 to 6 lymph nodes around the tumor site.
- A tumor is there in any esophagus part and has grown into the third esophagus layer. Cancer cells also spread to 1 to 2 lymph nodes.
- The cancer spreads beyond the esophagus to nearby tissue, not lymph nodes or other body areas.
For any of the below esophageal cancer staging conditions:
- It is in any esophagus part and grows into the third esophagus layer. It also spreads to 3 to 6 lymph nodes.
- A tumor is present in any esophagus part and grows into the outer esophagus layer and to either 1 to or 3 to 6 lymph nodes.
- The tumor is present in any esophagus part and spreads to structures nearby the esophagus. It either spreads to no lymph nodes or only on 1 to 2 lymph nodes.
For any of such esophageal cancer staging conditions:
- It is there in any esophagus part and moved to nearby areas. The tumor either moves to up to 3 to 6 lymph nodes.
- The cancer moved to up to 7 or more nearby lymph nodes.
In this level of esophageal cancer staging, cancer has spread to other body parts

Adenocarcinoma Staging Of The Esophagus
Doctors use T, N, and M staging for esophageal cancer and the grade (G).
Stage O: The cancer is present in only the top esophagus lining.
Stage IA: Cancer cells spread to the esophagus lining and the underneath layers.
Stage IB: Cancer can have either of the stage IB esophageal cancer staging characteristics.
- the tumor spreads underneath the layers in the esophagus lining. You carefully classify tumor cells.
- Cancer grows into the esophagus layer known as submucosa.
Stage IC: The esophageal cancer staging meets either of the states.
- Cancer grows into layers underneath the submucosa of the esophagus lining. The cells aren’t classified properly.
- Cancer grows into the third esophagus layer. The cancer cells are average or well-classified.
Stage IIA: The cancer is in the third esophagus layer. It’s not easy to find the esophageal cancer staging of cells not classified properly.
Stage IIB: Any of the problems for the staging of esophageal cancer:
- Cancer is in the outer esophagus layer.
- The cancer is in the inner esophagus layer and spreads to one or two lymph nodes.
Stage IIIA: Either of the conditions must be there:
- Cancer is in the inner esophagus layers and spreads to 3 to 6 lymph nodes near the tumor.
- Cancer is in the third esophagus layer and spreads to 1 or 2 lymph nodes.
Stage IIIB: Doctors need you to meet any such conditions for this esophageal cancer staging:
- Cancer is in the third esophagus layer in 3 to 6 lymph nodes.
- The cancer moved to the outer esophagus layer to 1 to 2 or 3 to 6 lymph nodes.
- The tumor moved to areas near the esophagus and 1 or 2 lymph nodes.
Stage IVA: Is for any of the below esophageal cancer staging conditions:
- The tumor moves to areas near the esophagus with either no lymph nodes or 3 to 6 lymph nodes.
- The tumor has spread to 7 and more lymph nodes.
Stage IVB: Cancer is present in another body part for this esophageal cancer staging.
By chronic cancer, we mean cancer that comes back again after treatment. It can come back in the esophagus or another body part. If cancer returns, doctors conduct another test round to know more about the time of relapse.
Treatment According To Stage
The TNM esophageal cancer staging helps the doctor tell the type of treatment you need. It is also based on:
- The cancer type (the cell types that your cancer starts in)
- Where do you find the cancer
- If any other health problems, you’ve got
The esophageal cancer staging and other factors also offer an idea of the prognosis.
- Surgery – to remove part of the esophagus
- Symptom control treatment
- Target cancer drugs
- Chemo radiotherapy (chemotherapy with radiotherapy)
You can get treatment as a type of clinical trial.
To know more about the right methods for staging esophageal cancer and find the perfect treatment plan for patients, you can refer to University Cancer Centers and our expert researchers and scholars. They are on the quest to get the best intensive cancer treatments and focus therapies on fighting cancer and speeding up the healing.
