Enteropathy-associated T-cell lymphoma (EATL) and coeliac disease | CION Cancer Clinics
EATL is a rare T-cell lymphoma that starts in the small intestine, and most cases grow out of long-standing coeliac disease. Warning signs are weight loss, belly pain and loose motions that return despite a strict gluten-free diet. It is confirmed only by a biopsy and is usually treated with chemotherapy. This page explains the tests, the treatment, and what it cannot tell you about your own outlook. At CION Cancer Clinics, our haematology team plans myeloma and lymphoma care with you, discussed at a tumour board and explained in plain words.

The short answer
What is EATL, and why is it linked to coeliac disease?
EATL, short for enteropathy-associated T-cell lymphoma, is a rare blood cancer that starts in the lining of the small intestine. Most cases grow out of long-standing coeliac disease, where gluten keeps the gut lining inflamed for years.
What goes wrong in the gut
In coeliac disease, gluten from wheat, barley and rye sets off an immune reaction in the small intestine. A type of white blood cell called a T cell gathers in the lining. In a small number of people, one family of these T cells starts to multiply out of control. That growth is the lymphoma.
Who it usually affects
It is mostly seen in adults in middle or later life. Many have known coeliac disease that stopped responding to a gluten-free diet. Some were never told they had coeliac disease at all, and the lymphoma is how it comes to light. Coeliac disease is more common in wheat-eating parts of North India, but families in Hyderabad and across Telangana and Andhra Pradesh see it too, and it is often missed for years.
Why it matters to find it early
The lymphoma sits in the bowel wall, where it can cause a tear or a blockage. It also makes it hard to absorb food, so people lose weight and strength quickly. Both of these affect how much treatment the body can take.
Having coeliac disease does not mean you will get this lymphoma. Nearly everyone with coeliac disease never does.Not sure whether this applies to you?

One thing that cannot wait
Sudden, severe belly pain, a hard swollen tummy, vomiting that will not stop, blood in the stool or black stools, or fainting can mean the bowel has torn, bled or become blocked. Go to the nearest emergency department now, or call 108. Say that you have coeliac disease or a bowel lymphoma. Do not wait for your clinic appointment, and do not take painkillers at home to see if it settles.
Finding it
How is EATL usually diagnosed?
-
Symptoms that do not settle
Belly pain, loose motions, weight loss, tiredness, fevers or night sweats in someone whose coeliac disease was under control. These signs are common with many gut problems, so they need testing, not guessing.
-
Blood tests and scans
Blood counts, liver and kidney tests, and markers of nutrition. A CT or PET-CT scan, which shows active areas in the body, helps find thickened bowel and enlarged lymph nodes, the small glands that filter body fluid.
-
A look inside the gut
An endoscopy passes a thin camera through the mouth into the small intestine. Sometimes a swallowed capsule camera or a longer scope is needed to reach further along.
-
A tissue sample
The diagnosis comes only from a biopsy, a small piece of tissue read under the microscope. Special stains show which kind of T cell is growing. Sometimes the sample is taken during emergency surgery for a tear or blockage.
-
Expert review of the slides
Because this lymphoma is rare, ask whether a haematopathologist, a doctor who reads blood cancer samples, has reviewed the slides. A second opinion on the tissue is reasonable and common.

Treatment
How is it treated, and who does intensive treatment not suit?
Treatment is usually chemotherapy, the drugs that kill fast-growing cells, given in cycles. In fit patients who respond well, the team may then discuss a stem cell transplant using the patient's own cells, to try to keep the lymphoma away for longer.
Getting strong enough to start
Many people are underweight and poorly nourished when they are diagnosed. Feeding support comes first, sometimes through a drip or a tube. A dietitian plans this with you. Surgery is used mainly to repair a tear or remove a blocked section of bowel, not as the main treatment.
Where a transplant happens
CION's haematology team, led by Dr. Basudev Pokhrel, reviews your case, presents it at a tumour board and coordinates any transplant with a qualified transplant centre. Ask early whether you might be a candidate, so the timing can be planned.
Who intensive treatment does not suit
Very strong chemotherapy and a transplant are hard on the body. They may not suit someone who is frail, very underweight, recovering from major bowel surgery, or living with serious heart, lung or kidney disease. For them, gentler treatment aimed at control and comfort can be the right choice. That is a medical decision, not giving up.
Newer targeted drugs and clinical trials exist for some people. Ask your haematologist whether any fit your situation.Commonly believed
What do families often get wrong about this lymphoma?
"Eating chapati caused this cancer."
Gluten does not cause lymphoma in people without coeliac disease. In coeliac disease, ongoing gut damage raises the risk over many years. Nobody in the family should blame themselves for past meals.
"Now that it is lymphoma, the gluten-free diet no longer matters."
If you have coeliac disease, the diet still protects the gut and helps you absorb food. Ask your team and dietitian before changing anything, especially during treatment.
"Tummy pain and loose motions are just the coeliac playing up."
If symptoms return while you are strictly gluten-free, or you are losing weight without trying, that needs tests. Treating it as a flare for months is how this lymphoma is found late.
"Everyone in the family will get it."
Coeliac disease can run in families, so close relatives may be offered a simple blood test for it. The lymphoma itself is rare, and relatives are not routinely screened for it.
On your report
What do the words on the biopsy report mean?
- Enteropathy
- Damage to the lining of the intestine. In this setting it usually means coeliac damage around the tumour.
- Villous atrophy
- The tiny finger-like folds that absorb food have flattened. It is the typical sign of coeliac disease.
- Intraepithelial lymphocytes
- T cells sitting inside the gut lining. Raised numbers are seen in coeliac disease and in the early changes before lymphoma.
- CD3, CD30, CD56, CD8
- Markers stained on the cells. They help tell EATL from MEITL and guide whether some targeted drugs might be considered.
- T-cell receptor rearrangement
- A gene test showing whether the T cells come from one abnormal family. A single family points towards lymphoma rather than inflammation.
Questions we are asked
Common questions about EATL and coeliac lymphoma
My father has had coeliac disease for years. Should we worry about lymphoma?
Most people with coeliac disease never develop lymphoma. The risk is higher when the disease is not controlled or stops responding to the diet. What matters is to watch for new weight loss, belly pain, fevers or loose motions despite a strict gluten-free diet, and to get these checked rather than waiting.
Can a blood test show EATL?
No. Blood tests show how the body is coping, such as low haemoglobin or low protein, and a coeliac antibody test can point to coeliac disease. But the lymphoma itself is confirmed only by a biopsy of the bowel or a lymph node, read by a specialist under the microscope.
Is EATL the same as bowel cancer?
No. Bowel cancer usually starts in the large bowel from the cells lining it. EATL is a lymphoma, a cancer of immune cells, and it starts in the small intestine. The tests, the treatment and the specialists involved are different, so it is treated by a haematologist rather than only a surgeon.
What is the outlook with this lymphoma?
EATL is a serious lymphoma, and it is often found late. The outlook depends on how fit and well-nourished the person is, how far it has spread, whether the bowel has torn, and how it responds to first treatment. Your haematologist can talk through your own picture; this page cannot.
Will my father need surgery?
Surgery is often needed when the bowel tears, bleeds or becomes blocked, and sometimes it is how the diagnosis is made. It is not usually the main treatment for the lymphoma itself. After recovery, chemotherapy is planned. Ask the surgeon to send the tissue for full lymphoma testing.
What should he eat during treatment?
If he has coeliac disease, food should stay gluten-free. Beyond that, the aim is enough calories and protein to keep weight on. Soft rice, dal, curd, eggs and idli are often easier to manage. A dietitian can add supplements. Do not start herbal or home remedies without asking the team.
Does CION do stem cell transplants for EATL?
CION's haematology team assesses the case, plans chemotherapy, discusses it at a tumour board and, where a transplant is right, coordinates referral to a qualified transplant centre. Ask early whether a transplant is being considered, so tests and timing can be arranged without losing time.
Is it covered by Aarogyasri or insurance?
Lymphoma treatment is often covered under Aarogyasri, PM-JAY, CGHS, ECHS, EHS and many cashless insurance policies. Scheme rules change, so check your current entitlement before treatment starts. Call the helpline with your card details and we will help you check what your cover includes.
