Do you sometimes get lumps like this on your body? Or do you feel tired for no reason, or do you feel like you're losing weight? Most of the time, these can be normal things, but sometimes they can be a sign of a disease that needs some attention. Today we're going to talk about a rare type of lymphoma called `(Marginal Zone Lymphoma - MZL)` that we all need to be aware of. Don't worry, we'll talk about this simply and in a way that you can understand.
What is `(Marginal Zone Lymphoma - MZL)`? Simply put...
Marginal Zone Lymphoma is a common name for several rare types of lymphoma that grow slowly, meaning they don't spread very quickly, and belong to a group of cancers called Non-Hodgkin Lymphoma. These usually develop in the lymphoid tissue, which is part of our body's immune system . These tissues contain a type of white blood cell called B cells. Did you know that B cells are like the body's sentinels, a type of cell that helps protect us from disease? They are found mostly in our lymph nodes (also called lymph nodes) and spleen.
Now look, inside our lymph nodes there are small areas called `(lymphoid follicles)`. These `(lymphoid follicles)` have two zones - one is called `(mantle zone)` and the other is called `(marginal zone)`. Just like adding another layer to a cake, this `(marginal zone)` is located around the `(mantle zone)`. `(Marginal Zone Lymphoma)` is formed when the `(B cells)` cells in that `(marginal zone)` become mutated , that is, they undergo some change, become abnormal cells, and start to multiply uncontrollably.
This condition, ``Marginal Zone Lymphoma'', is usually seen most often in people over the age of 60. It is also slightly more common in men than in women.
What are the main types of `(Marginal Zone Lymphoma)`?
There are three main types of `(MZL)`. Let's see what they are:
1. Mucosa-assisted lymphoid tissue (MALT) lymphoma: This is the most common type of MALT. Doctors sometimes call it extranodal marginal cell lymphoma. "Extranodal" means it starts outside the lymph nodes. This type of lymphoma can start in the lining of the stomach (gastric MALT), or in the lungs, skin, thyroid, salivary glands, intestines, or areas around the eyes (non-gastric MALT).
2. Nodal marginal zone lymphoma: This type affects your lymph nodes . That is, your lymph nodes. But sometimes it can also be seen in your bone marrow.
3. Splenic marginal zone lymphoma: This is a rare type. It affects your spleen, blood, and bone marrow.
What are the symptoms of `(Marginal Zone Lymphoma)`?
Marginal Zone Lymphoma is often a very slow-growing disease. So, you may have the condition for a long time without any symptoms. Symptoms vary depending on the type of lymphoma. In general, Marginal Zone Lymphoma can cause symptoms like:
- Fever (fever that comes on without a reason)
- Excessive sweating at night (so much that the bed sheets get wet)
- Weight loss for no reason (if you lose weight without trying)
We sometimes call these "B traits."
Symptoms of `(MALT)` Lymphoma
The symptoms of `(Extranodal marginal zone lymphoma)` or `(MALT)` lymphoma vary depending on where the lymphoma is located. For example, if you have `(MALT)` lymphoma in your stomach, you may experience symptoms like these:
- Nausea and vomiting
- Stomach pain or discomfort
- Feeling full even after eating a small amount of food
If the lymphoma is located elsewhere than in the stomach (non-gastric MALT), for example in the eye, changes may be seen in the conjunctiva or lacrimal glands.
Symptoms of `(Nodal marginal zone lymphoma)`
In this type, the main symptom is swelling of the testicles. In addition, the previously mentioned common symptoms may also occur:
- Fever
- Night sweats
- Weight loss for no reason
Symptoms of `(Splenic marginal zone lymphoma)`
This type of spleen cancer can cause symptoms such as:
- Fatigue and fatigue
- Enlarged spleen (may feel heavy or full in the upper left part of the abdomen)
- Night sweats
- Weight loss for no reason
What are the causes of `(Marginal Zone Lymphoma)`?
Typically, people with Marginal Zone Lymphoma have a family history of lymphoma, or they may have frequent infections, or they may have autoimmune diseases. However, there are specific causes for each subtype.
- MALT lymphoma: This is most commonly caused by bacterial infections, especially H. pylori. You may have heard that gastritis is also caused by this bacteria. In addition, autoimmune diseases such as Hashimoto's disease (a disease that affects the thyroid gland) or Sjögren's syndrome (a disease that dries out the salivary and tear glands), and a family history of lymphoma can also be a risk factor.
- Splenic marginal zone lymphoma: This is associated with hepatitis C virus infection and autoimmune diseases.
- Nodal marginal zone lymphoma: This has also been found to be associated with Hepatitis C infection.
Important: Not everyone will develop `(MZL)` despite having these causes. Also, some people can develop it without any of these causes. These are only risk factors.
What are the risk factors for `(Marginal Zone Lymphoma)`?
As mentioned earlier, the main risk factors are a family history of lymphoma, certain infections (such as H. pylori, Hepatitis C), and autoimmune diseases (Hashimoto's disease, Sjögren's syndrome).
How is Marginal Zone Lymphoma diagnosed?
Your doctor will first ask you a few questions to diagnose this condition. This includes what symptoms you have, your medical history, and whether anyone in your family has had similar conditions.
After that, several tests will have to be done to confirm the diagnosis.
What are the diagnostic tests?
The tests that are done may vary slightly depending on the subtype of lymphoma, but in general, the following tests may be done:
- Complete Blood Count (CBC): Checks the number of different types of cells (red cells, white cells, platelets) in the blood.
- `(LDH - Lactate Dehydrogenase)` test: This is an enzyme that increases in the blood when cells are damaged.
- `(Beta-2 microglobulin)`: This is used as an indicator in blood cancers.
- Liver function tests .
- Renal (kidney) function tests .
- Serum protein immunofixation (IFX): A test to look for changes in proteins in the blood.
- Tests for certain bacterial and viral infections (e.g., `(H. pylori)`, `(Hepatitis C)`).
- `(CT scan)`: Take detailed pictures of the inside of the body. See things like swollen lymph nodes and an enlarged spleen.
- Needle biopsy: A small sample of tissue from a swollen lymph node or other area is removed with a needle and examined under a microscope. This is the only way to tell for sure if lymphoma cells are present.
- Bone marrow biopsy: This test is sometimes done to see if the lymphoma has spread to the bone marrow.
- Other `(Biopsy)` tests: Taking a sample of cells or tissue from any area of the body that is thought to be affected and testing it.
What are the stages of cancer in `(MZL)`?
Staging a cancer is a way of determining how far the cancer has spread in the body. This is important for planning treatment and getting an idea of the future course of the disease. The stages of MZL are usually as follows:
- Stage I: The cancer is in only one lymph node region.
- Stage II: The cancer is in two or more lymph node regions on the same side, either above or below the diaphragm (the muscle that separates our chest and stomach).
- Stage III: The cancer has spread to multiple lymph node regions above and below the diaphragm, meaning there are lymph nodes on both sides.
- Stage IV: The cancer has spread outside the lymphatic system to one or more other organs, such as the liver, lungs, or bone marrow.
What are the treatments for `(Marginal Zone Lymphoma)`?
Because Marginal Zone Lymphoma is a very slow-growing disease, some people may not need to start treatment right away. Doctors sometimes recommend a treatment approach called "watchful waiting" or "active surveillance." This means that you are monitored regularly until symptoms appear or the disease gets worse.
If treatment is needed, the treatment given will vary depending on the subtype of lymphoma. Common treatments include:
- Antibiotics: Especially if the lymphoma is caused by the bacteria H. pylori, antibiotics are given to kill the bacteria. In many cases, this can cure the lymphoma.
- Chemotherapy: Drugs given to kill cancer cells.
- Radiation therapy: The use of high-energy rays to destroy cancer cells. This is usually used when the lymphoma is localized.
- Targeted therapy: These are new types of drugs that work by targeting specific molecules in cancer cells.
- Immunotherapy: Stimulates the body's own immune system to fight cancer cells.
Can `(Marginal Zone Lymphoma)` be completely cured?
This really depends on the type of lymphoma, the stage, and your overall health. For example, gastric (MALT) lymphoma caused by H. pylori infection has a high chance of being completely cured with antibiotic treatment.
In other types, treatment can put the disease into ``remission'' . ``Remission'' means that symptoms have disappeared and tests show no evidence of the disease. However, ``Marginal Zone Lymphoma'' can sometimes come back (``recur'') after treatment. Therefore, doctors will continue to monitor you.
What is the survival rate for `(Marginal Zone Lymphoma)`?
Survival rates are just statistics. They show the percentage of people who are alive five years after diagnosis. But they can vary from person to person. Your experience may vary.
According to one study:
- About 88% of people with extranodal marginal zone lymphoma (MALT) are alive five years after diagnosis.
- About 79% of people with splenic marginal zone lymphoma are alive five years after diagnosis.
- About 76.5% of people with nodal marginal zone lymphoma are alive five years after diagnosis.
Remember: These are just averages. Because Marginal Zone Lymphoma usually occurs in older people, many of these people die from causes other than lymphoma. Only your doctor can give you the best information about your situation. So, don't be alarmed by these statistics alone.
Can Marginal Zone Lymphoma be prevented?
We cannot control some of the factors that contribute to the development of this disease, such as autoimmune diseases or genetic influences. However, if there is an infection with `(H. pylori)`, it can be reduced to some extent by taking appropriate treatment and taking steps to protect yourself from infections such as `(Hepatitis C)`.
When should I see my doctor?
If you have been diagnosed with ``Marginal Zone Lymphoma'', be sure to see your doctor if:
- If you notice changes in your body that you think could be symptoms of Marginal Zone Lymphoma (e.g., a new lump appears, an existing one gets bigger, fever, night sweats, weight loss).
- If your symptoms get worse while you are receiving treatment .
- If you are in remission and start to see signs that the disease is coming back, it could be a case of recurring .
How should I take care of my health?
When living with a disease like MZL, self-care is very important. Here are some things you can do:
- Manage stress: Some people with MZL may not have symptoms and may not need treatment. While that's a good thing, you may still be worried about "when will it get worse?" Exercise, listening to music, doing yoga, or engaging in a hobby you enjoy can help you relax.
- Drink enough water: Cancer treatments and their side effects can dehydrate the body, so try to drink at least 8 glasses of water a day.
- Eat a well-balanced diet: Include nutritious foods like fruits, vegetables, nuts, and dairy products in your diet. Eat small meals instead of large meals.
What questions should I ask my doctor?
You can ask the doctor questions like these:
- What type of ``Marginal Zone Lymphoma'' do I have?
- What is the stage of my disease?
- Do I need treatment right away?
- If treatment is needed, what treatment would you recommend and why?
- What are the side effects of these treatments?
- Are there any clinical trials I can participate in?
- What can you tell me about the prognosis of my disease?
Finally, what to remember (Take-Home Message)
Marginal Zone Lymphoma (MZL) is a rare, slow-growing type of lymphoma that falls into the category of Non-Hodgkin Lymphoma. There are several types of lymphoma, and the symptoms, treatment, and prognosis vary depending on the type. Most importantly, because the disease progresses very slowly, some people may not need treatment for years. For others, treatment can put the disease into remission.
If you have this disease, it is best not to panic, but to talk to your doctor and get information tailored to your situation. Your doctor will explain to you how this disease affects your body and the treatment options available. Remember, you are not alone, and there are doctors and your loved ones who can help you.
