Anaplastic large cell lymphoma (ALCL) is a rare type of non-Hodgkin lymphoma (NHL). Like all lymphomas, it’s a cancer of the lymphatic system – part of the body’s immune system.
ALCL is more common in children and young adults. It develops when abnormal T-cell lymphocytes, a type of white blood cell, divide in an uncontrolled way. These build up in parts of the body like the lymph nodes, lungs or skin. This may cause:
Doctors describe ALCL as ALK positive or ALK negative. This depends on whether a protein, called anaplastic lymphoma kinase (ALK), is on the lymphoma cells.
ALCL grows quickly and usually needs immediate treatment with chemotherapy. Some people may also have radiotherapy or stem cell transplants. Your doctor may invite you to take part in a clinical trial if a new treatment is being researched for ALCL.
ALCL often responds well to chemotherapy and disappears with treatment (remission). But sometimes it can come back and needs further treatment to try and control it.
Non-Hodgkin lymphoma (NHL) is a cancer of the lymphatic system. This system is part of the body’s immune system, which helps us fight infection.
It is made up of organs such as the bone marrow, thymus, spleen and lymph nodes (sometimes called lymph glands).
There are lymph nodes all over the body. They are connected by a network of tiny tubes (lymphatic vessels) that contain lymph fluid. As lymph fluid flows through the lymph nodes, the nodes collect and filter out things that the body doesn't need. This includes bacteria, viruses, damaged cells and cancer cells.
Lymph fluid contains lymphocytes. These are white blood cells that help the body fight infection and disease.
Lymphocytes grow in the bone marrow, where blood cells are made. The two main types of lymphocyte are B-cells and T-cells. B-cells mature in the bone marrow. T-cells mature in the thymus gland behind the breastbone. When they are mature, both B-cells and T-cells help fight infections.
Lymphoma is a disease in which either T-cells or B-cells grow in an uncontrolled way.
There are many different types of non-Hodgkin lymphoma. They're grouped (or classified) according to things like the type of cell involved (B-cells or T-cells) and how quickly the lymphoma grows.
ALCL is rare. It is more likely to affect children and young adults, and is more common in males.
ALCL is usually made up of abnormal T-cells. These cells may build up in lymph nodes. They may also occur in other parts of the body such as the skin or lungs.
ALCL can be divided into one of two groups. If there is a protein called anaplastic lymphoma kinase (ALK) on the lymphoma cells, it’s described as ALK positive. If there isn’t, it’s described as ALK negative.
We have other information about NHL in children and NHL in young adults.
The causes of ALCL are unknown.
Like other cancers, it's not infectious and can't be passed on to other people.
The first sign of ALCL is often a painless swelling in the neck, armpit or groin. This is caused by enlarged lymph nodes. Sometimes, lymph nodes in more than one part of the body are affected.
Some people have symptoms relating to where the lymphoma is in their body. For example, if the lymphoma is in the chest area, it may cause a cough or breathlessness.
General symptoms may include loss of appetite and tiredness.
Some people may also have night sweats, high temperatures (fevers) or weight loss. These are known as B symptoms.
If you have an enlarged lymph node, the doctors will remove it during a small operation. This is called a biopsy. It may be done under a local or general anaesthetic. The lymph node will be examined under a microscope. The doctors may also take biopsies from other areas of the body.
You may have some other tests, such as:
These tests can find out more about the lymphoma, such as its stage and grade (see below). Doctors use this information to decide which treatment is best for you. We have more information about tests for non-Hodgkin lymphoma.
Your doctors will look at how many groups of lymph nodes are affected, and whether the lymphoma has spread to other organs. This is called staging.
A group of lymph nodes refers to lymph nodes in one area of the body, such as in the armpit, on one side of the neck or in the groin.
One group of lymph nodes in one area of the body is affected.
Two or more groups of lymph nodes are affected. All the affected nodes are either above the diaphragm or below the diaphragm. The diaphragm is a sheet of muscle under the lungs.
The lymphoma is in lymph nodes both above and below the diaphragm.
The lymphoma has spread beyond the lymph nodes to other organs such as the bone marrow, liver or lungs.
Doctors add either the letter A or B after the stage number. This is to show whether you have any B symptoms such as a high temperature, night sweats or weight loss.
If you don't have any of these symptoms, the letter A will be added next to the stage. If you do have them, the letter B is added.
Sometimes, the lymphoma can start outside the lymph nodes. This is called extranodal lymphoma. In this case, the stage will include the letter E (for extranodal).
Doctors also divide non-Hodgkin lymphomas into two groups depending on how they grow:
ALCL is an aggressive lymphoma. It is fast-growing and usually needs treatment straight away with chemotherapy.
Chemotherapy is the main treatment for ALCL. Some people may also have radiotherapy or stem cell treatments.
ALCL usually responds well to chemotherapy and treatment may make it disappear (remission). There's a risk that the lymphoma may come back (relapse) in the future. If this happens, chemotherapy and stem cell transplants can be used to try to control it.
Chemotherapy is the use of anti-cancer (cytotoxic) drugs to destroy cancer cells.
ALCL is usually treated with a combination of chemotherapy drugs. The drugs are given into a vein (intravenously).
A chemotherapy treatment called CHOP is often used. You can have this treatment as an outpatient.
CHOP is named after the initials of the drugs used, which are:
More intensive combinations of drugs may be used to treat young adults and children with ALCL. This may mean longer stays in hospital.
Radiotherapy uses high-energy rays to destroy cancer cells, while doing as little harm as possible to normal cells. Radiotherapy may be given after chemotherapy. Occasionally, radiotherapy may be used alone if the lymphoma is stage 1 (see above).
Some people may have treatment using stem cells. These treatments are not suitable for everyone.
Stem cells are blood cells at their earliest stage of development. All blood cells develop from stem cells. There are two different types of stem cell treatment:
Steroids are often given with chemotherapy to treat lymphomas. They also help you feel better and can reduce feelings of sickness.
New treatments for ALCL are being researched all the time. Your doctor may invite you to take part in a clinical trial. Trials compare new treatments with the best available standard treatments. Before you enter a trial, your doctor must discuss the treatment with you and get your consent (permission).
Before any trial is allowed to take place, it must be approved by a research ethics committee, which protects the interests of those taking part.
You can decide not to take part or to withdraw from the trial at any stage. You will then receive the best standard treatment available.
Everyone has their own way of dealing with their illness and the different emotions they experience. You may find it helpful to talk to family and friends or your doctor or nurse. You can also contact our cancer support specialists or the organisations listed below for more information and support.
The Lymphoma Association gives emotional support, advice and information on all aspects of Hodgkin lymphoma and non-Hodgkin lymphoma. It has a national network of people with lymphoma and local groups.
Leukaemia CARE is a national group promoting the welfare of people with leukaemia and other blood disorders, including non-Hodgkin lymphoma. Has regional support groups in many counties.

Hi John, Yes that is my opinion also. I am seeing my Consultant on the 22nd April so I shall be mentioning these pains to him. ...
