Stage 3 oesophageal cancer
The stage of your cancer tells the doctor how far it has grown and if it has spread.
Staging is very complicated. It depends on:
- what type of oesophageal cancer you have (squamous cell or adenocarcinoma)
- the grade of your cancer (how abnormal the cells look)
- whether doctors stage your cancer using tests and scans (clinical staging) or after surgery (pathological staging)
When you read the information on this page, it's helpful to know what type of oesophageal cancer you have and whether the doctor is using pathological or clinical staging. Talk to your specialist doctor or nurse if you are unsure. They can help you understand more about your cancer stage.

Staging systems
Doctors use different systems to stage oesophageal cancer. This page is about stage 3 cancer, which is part of the number staging system. This system has 5 stages, stage 0 (high grade dysplasia) to stage 4.
This page also tells you what stage 3 means in the TNM system. This system describes:
- the size of the primary tumour (T)
- whether the cancer has spread to the lymph nodes (N)
- whether the cancer has spread to another part of the body (M)
Squamous cell cancer
Squamous cell cancers develop from squamous cells that make up the inner lining of your oesophagus.
Clinical staging means your doctor uses test and scan results to stage your cancer. This is different to pathological staging, which doctors use after surgery.
Your doctor might tell you your clinical stage to begin with. And if you go on to have surgery, your stage might change when the doctor finds out your pathological stage.
Stage 3 squamous cell cancer (clinical stage) can be any grade.
It means the cancer has grown no further than the outer layer (adventitia) of the oesophagus and is in up to 6 nearby lymph nodes.
In TNM staging, stage 3 is:
- T1, T2 or T3, N1 or N2, M0
Stage 3 squamous cell cancer (pathological stage) can be any grade.
It’s split into 2 stages - stage 3A and stage 3B.
Stage 3A means the cancer has grown no further than the thick muscle wall of the oesophagus. It has spread to up to 6 nearby lymph nodes.
In TNM staging, stage 3A includes:
- T1, N2, M0
- T2, N1, M0.
Stage 3B means the cancer has spread into the thick muscle wall or outer layer (adventitia) of the oesophagus. Or it has spread into nearby tissue such as the tissue covering the lungs (pleura), the outer covering of the heart (pericardium) or the muscle at the bottom of the rib cage (diaphragm).
It might have spread into up to 6 lymph nodes.
In TNM staging, stage 3B includes:
- T2, N2, M0
- T3, N1 or N2, M0.
- T4a, N0 or N1, M0.
Adenocarcinoma
Adenocarcinomas are cancers that develop in gland cells. These cells make mucus in the lining of the oesophagus.
Clinical staging means your doctor uses test and scan results to stage your cancer. This is different to pathological staging, which doctors use after surgery.
Your doctor might tell you your clinical stage to begin with. And if you go on to have surgery, your stage might change when the doctor finds out your pathological stage.
Stage 3 adenocarcinoma (clinical stage) can be any grade.
It means the cancer has spread into the thick muscle wall or outer layer (adventitia) of the oesophagus. Or it has spread into nearby tissue such as the tissue covering the lungs (pleura), the outer covering of the heart (pericardium) or the muscle at the bottom of the rib cage (diaphragm).
It might have spread into 1 or 2 lymph nodes.
In TNM staging, stage 3 includes:
- T2, N1, M0
- T3, N0 or N1, M0
- T4a, N0 or N1, M0
Stage 3 adenocarcinoma (pathological stage) can be any grade.
It’s split into 2 stages - stage 3A and stage 3B.
Stage 3A means the cancer has grown no further than the thick muscle wall of the oesophagus. It is in up to 6 nearby lymph nodes.
In TNM staging, stage 3A includes:
- T1, N2, M0
- T2, N1, M0
Stage 3B means the cancer has spread into the thick muscle wall or outer layer (adventitia) of the oesophagus. Or it has spread into nearby tissue such as the tissue covering the lungs (pleura), the outer covering of the heart (pericardium) or the muscle at the bottom of the rib cage (diaphragm).
It might be in up to 6 lymph nodes.
In TNM staging, stage 3B can include:
- T2, N2, M0
- T3, N1 or N2, M0
- T4a, N0 or N1, M0
Treatment for stage 3 oesophageal cancer
Your treatment depends on whether you have squamous cell cancer or adenocarcinoma.
For squamous cell cancer you usually have chemoradiotherapy. And then you either have:
- surgery to remove part or all of your oesophagus
- no further treatment and the doctors keep a close eye on you - this is called active surveillance
For adenocarcinoma you either have:
- chemotherapy before surgery
- chemotherapy before and after surgery
- chemoradiotherapy before surgery
You might have chemoradiotherapy without surgery if you aren't well enough or choose not to have surgery.
Some people might have immunotherapy treatment if there are any cancer cells left after surgery.
