Have you ever heard of a disease with such a strange name? Perhaps you or someone you know has been told this name by a doctor. Although it may seem a bit complicated, let's try to understand it simply. What happens is that a type of defense cell in our body called ``T cells'' turns into cancer cells.
What is angioimmunoblastic T-cell lymphoma (AITL)?
Simply put, Angioimmunoblastic T-cell Lymphoma (AITL) is a type of cancer that develops in the white blood cells in our blood called T lymphocytes, or T cells. Think of it like our body's defense system. They fight off harmful things like viruses and bacteria that enter our bodies and protect us from disease. Sometimes, these T cells can even destroy cancer cells.
However, sometimes one of these `T cells` can mutate, that is, change, and become a cancer cell. Then these bad cancer cells start dividing rapidly and multiplying uncontrollably. That is when this condition called `AITL` occurs. This is a cancer that falls into a subgroup called `peripheral T-cell lymphoma`, which belongs to the larger group called `non-Hodgkin T-cell lymphoma`. This cancer can sometimes spread to places like our liver, lungs, or `bone marrow`.
How common is this condition called AITL?
In fact, AITL is a relatively common type of T-cell lymphoma, but overall it is a very rare cancer . For example, in a country like the United States, AITL accounts for only 4% of all lymphoma patients. It also accounts for 1% to 2% of all non-Hodgkin lymphoma patients. It is most common in people over the age of 65 .
What are the symptoms of AITL?
Because AITL is a fast-growing cancer, symptoms can appear quickly. If you experience any of the following, you should be concerned:
- Fever that comes and goes without a reason: The body just gets hot and the fever comes, goes away, and comes back again. No specific cause can be found.
- Night sweats: Sweating so much while sleeping that the sheets get wet.
- Itching or skin irritation: It may appear all over the body, in spots, or it may be constantly itchy.
- Difficulty breathing: Feeling short of breath even with a little exertion.
- Joint swelling: The joints in the limbs may become swollen and possibly painful.
- Swollen nipples: They appear as lumps in places like the neck, armpits, and groin. These are often painless.
- Weight loss for no reason: Even if you don't control your diet or exercise much, you suddenly lose weight.
Because AITL affects our immune system , some people with the condition can develop conditions called autoimmune diseases, which are diseases in which our own immune system turns against us. For example, conditions like immune thrombocytopenia (low blood platelets) or autoimmune hemolytic anemia (destruction of blood cells).
What causes AITL?
AITL occurs when our T cells become abnormal and start to grow out of control. However, researchers are still not sure why some people develop this type of T-cell lymphoma and others do not.
There is a possibility that there may be a link between AITL and viral infections such as the Epstein-Barr virus. However, more information is needed to understand how this link works.
How is AITL diagnosed?
AITL is often diagnosed through a lymph node biopsy . This involves taking a small sample of tissue from a swollen lymph node or suspicious area and examining it under a microscope. If your test results show abnormal T lymphocytes, doctors will suspect AITL.
Once the diagnosis is confirmed, an oncologist will examine you and ask about your symptoms. They will also ask about your health history, such as previous illnesses and current medications.
In addition, the doctor may also perform several tests, such as:
- Blood tests.
- Bone marrow biopsy.
You may also have imaging tests like these:
- CT scan (CT - computed tomography scans).
- MRI scan (MRI - magnetic resonance imaging scans).
- PET scan (positron emission tomography scans).
AITL, like other lymphomas, can be difficult to diagnose. This is because the disease is complex, and the symptoms can develop slowly and can mimic those of other diseases. For these reasons, many AITL patients are diagnosed with the disease at a late stage . However, researchers are continuing to find ways to diagnose AITL and other lymphomas more quickly.
How is AITL treated?
Treatment for AITL depends on many factors, including your symptoms, the severity of the disease, and your overall health. The main treatments for AITL are:
- Chemotherapy: This involves giving a combination of different drugs to kill cancer cells. Steroids are also added. The most commonly used treatments are CHOP and BV+CHP. The name CHOP is an acronym for Cytoxan (cyclophosphamide), Hydroxydaunorubicin (hydroxydaunorubicin), Oncovin (vincristine sulfate), and Prednisone. BV+CHP is a combination of brentuximab vedotin, cyclophosphamide, doxorubicin, and prednisone. This is a bit complicated, but the doctor will explain it to you clearly.
- Stem cell transplant: This involves removing cancerous stem cells and replacing them with healthy stem cells. These healthy cells can be taken from you (`autologous`) or they can be donated from someone else (`allogeneic`).
- Targeted therapy: This treatment focuses only on the genetic mutations that turn healthy cells into cancer cells. This means that the drug goes straight to the bad cells and works only on those bad cells.
How long can you live with AITL?
AITL is a relatively aggressive cancer. Research shows that the median survival after diagnosis is less than three years . The "median" is the middle value in a range of values. This means that some people live shorter lives, while others live longer.
But here's an important point: Approximately 30% to 35% of people with AITL respond well to treatment and may even be cured without the cancer coming back.
Survival Rate for AITL
The five-year survival rate for AITL is between 30% and 35% . This means that out of 100 people diagnosed with AITL, between 30 and 35 are still alive after five years. Similarly, the seven-year survival rate is around 29%.
It's normal to feel scared and anxious when you see these statistics. But remember, these are just estimates. They are based on the past experiences of others who have been diagnosed with the same disease as you. Everyone's health history and genetic background are different. Therefore, these survival rates cannot predict exactly how long you will live or how you will respond to treatment.
If you're concerned about these statistics, or if you want to know how they might affect you, be sure to talk to your doctor. He/she can explain your situation and provide any help you need.
Can AITL be prevented?
Most people with AITL have no known risk factors for developing the disease. There is no specific way to prevent AITL or any other type of lymphoma. Like most cancers, this is something that happens sometimes. It doesn't mean you did anything wrong.
Can I reduce my risk?
Although you can't prevent angioimmunoblastic T-cell lymphoma, you can do these things to maintain a healthy immune system :
- Eat a well-balanced diet: Eat foods rich in vegetables, fruits, legumes, whole grains, and protein, such as lean meats and fish.
- Exercise regularly: Do something like walking or running for at least 30 minutes a day.
- Get good sleep: Get at least 7-8 hours of sound sleep a day.
- Maintain a healthy weight that suits you.
- Avoid smoking and tobacco use: Like cigarettes and bidis, smokeless tobacco (such as chewing tobacco and chewing gum) is also harmful. Vaping is also not good.
- Limit alcohol consumption.
When should I see a doctor?
If you develop symptoms such as a sudden rash, swollen lymph nodes, high fever, or unintentional weight loss, see a doctor immediately.
If you are already being treated for AITL, notify your oncologist immediately if you develop new symptoms or if your symptoms suddenly worsen. Given the nature of this cancer, it is very important to start treatment as soon as possible.
AITL affects everyone differently. Your doctor is the only person who can explain how your diagnosis will affect you. Some people don't want to know the details of the disease, and that's okay. You have the right to make decisions about your treatment. Only you know what is best for your mental, emotional, and spiritual well-being.
What questions should I ask my doctor?
It's normal to have many questions after a diagnosis of AITL. Here are some questions you can ask your oncologist:
- How advanced is my cancer?
- Has the cancer spread to my other organs?
- What treatment options do I have?
- How soon should I start treatment?
- Can I continue my job while receiving treatment?
- What kind of support and help will I need during treatment?
- Can I join support groups or other resources?
- How do I maintain my mental health?
A cancer diagnosis can bring on a variety of difficult emotions, including sadness, anxiety, anger, and frustration. Because AITL is a rare disease, you may feel alone and like no one understands you. But your medical team is there to help you. They can tell you about the resources you need and support groups that have people who have been through the same things as you. You don't have to go through this journey alone. Get the support of your loved ones and your doctors.
