Have you ever heard of Acute Monocytic Leukemia, or AMoL? The name may sound a bit strange, but it is a type of cancer that affects the blood. Imagine if something went wrong in our body's blood-forming cells, and instead of healthy blood cells, cancer cells started to form? That's what happens in this case. Although this is a bit of a serious story, let's talk about it simply, in a way that you can understand.
What is this so-called Acute Monocytic Leukemia?
Simply put, Acute Monocytic Leukemia (AMoL) is a type of cancer that belongs to the leukemia group called Acute Myeloid Leukemia (AML). You know that leukemia is a blood cancer. So this AMoL is also a blood cancer . It occurs when there is a defect in the process of forming blood cells inside our body. To be precise, the immature cells that should become healthy blood cells, that is, cells called blasts , mutate and become cancer cells.
In AMoL, these immature cells, or blasts, are stopped in their tracks as they develop into a type of white blood cell called monocytes . However, instead of becoming healthy monocytes, they become stuck at the immature, or blast, stage and become cancer cells.
Acute monocytic leukemia is a very serious, fast-spreading cancer . Your doctor will help you find the best treatment for your condition. Don't worry, we'll talk about this in more detail.
Are there types of this?
Yes, the World Health Organization (WHO) classifies AMoL based on the type of cell that becomes cancerous (i.e., monocytes). It is also called AML-M5 according to the older French-American-British (FAB) classification system. Under this system, AML-M5 is further divided into two categories:
Acute monoblastic leukemia (AML-M5a)
In this type, at least 80% of the cells become cancerous before they are fully developed. This type is most often seen in young children and young adults .
Acute monocytic leukemia (AML-M5b)
In this, very abnormal cells become cancerous at a slightly advanced stage of cell growth. This type does not specifically affect a certain age group .
These classifications help doctors diagnose the disease. However, one type is not more serious than the other. Both are conditions that require the same level of attention.
What are the symptoms of this?
Symptoms of AMoL often appear and progress quickly . Here are some of the symptoms:
- Bruising and bleeding easily (bleeding gums, frequent nosebleeds, etc.) Imagine that you bruise badly even if you just bump your head, or your gums bleed excessively when you brush your teeth.
- Small, purple, red, or brown dots under the skin ( petechiae ). These may look like small pimples, but they are actually spots of blood leaking under the skin.
- Swelling of the gums or overgrowth of gum tissue.
- Weakness and extreme fatigue . Just feeling like you have no energy. Feeling tired even when you wake up in the morning.
- Difficulty breathing.
- The food is tasteless.
- Weight loss for no reason . If you're losing weight without dieting, it's something to pay attention to.
- Pale skin.
- Dizziness.
- Fever.
Sometimes, acute monocytic leukemia can affect your brain and central nervous system . If this happens, you may experience symptoms such as difficulty remembering and concentrating.
Why does this kind of disease occur?
Medical experts still don't know exactly what causes AMoL. But it's thought that it's most likely caused by genetic mutations , or changes in the DNA of cells. These changes are what cause a healthy cell to become cancerous.
Researchers have found that in some people with AMoL, there is a genetic disorder called a chromosomal rearrangement. This means that a piece of one chromosome breaks off and attaches to another chromosome. This is called a chromosomal translocation . This disorder can cause a cell to stop developing as a monocyte and become a cancer cell. Think of it like something that has gone wrong.
Research into these genetic changes is still ongoing. Understanding the genetics behind cancer will help experts develop better treatments to fight it.
What are the risk factors for developing this disease?
There are several factors that can increase the risk of developing Acute Monocytic Leukemia. Here are some of them:
- Smoking and exposure to secondhand smoke . Even if you don't smoke, being around people who smoke is also risky.
- If you have previously received treatment for cancer, for example chemotherapy and radiation therapy.
- Long-term exposure to carcinogens , such as chemicals like benzene and formaldehyde (which can be found in some factories and paints).
- Exposure to radiation after a nuclear reactor accident or atomic bomb.
- If you have a genetic disease that is passed down through generations, for example , Li-Fraumeni syndrome .
- If you have diseases related to the bone marrow, such as myeloproliferative neoplasms .
But it's important to remember that having a risk factor doesn't mean you will definitely get cancer . However, it's much better to avoid risks that you can control, like not smoking.
What are the possible complications of this disease?
When you have AMoL, abnormal cells can build up in your bone marrow . As you know, the bone marrow is where blood cells are made. So when these cancer cells grow, they crowd out healthy blood cells. This can lead to a decrease in red blood cells, white blood cells, and platelets, which can lead to various complications. For example:
- Anemia : A condition caused by a decrease in red blood cells. This can cause fatigue and paleness.
- Neutropenia : A decrease in neutrophils, a type of white blood cell, which increases the risk of infection.
- Thrombocytopenia : A decrease in platelets, which help blood clot. This can cause increased bleeding even from a minor injury.
How do you recognize this disease?
Doctors use a series of tests to diagnose AML. According to the World Health Organization, a person is considered to have AML if 20% or more of their blood cells are abnormal, immature cells. Also, more than 80% of those abnormal cells must be monocytes or monocyte precursors.
Your doctor will take a blood sample, or a sample of tissue, fluid, or bone marrow. These are actually tested in a lab.
These are the tests used to diagnose AMoL:
- Blood tests : A complete blood count (CBC ) can reveal signs of AMoL, such as an increased white blood cell count. A peripheral blood smear can check for abnormal cells.
- Bone marrow biopsy : For this test, your doctor takes a sample of tissue or fluid from your bone (usually your hip bone). The sample is then examined under a microscope to check for cancer cells. This can be a little painful, but it is essential for diagnosis.
- Spinal tap : To see if cancer cells have spread to the brain or central nervous system, the doctor takes a sample of your spinal fluid and tests it.
- Immunophenotyping : This test looks for specific proteins on the surface of cells. These proteins help identify the cells as AMoL cells.
- Cytogenic analysis : This type of analysis checks for translocations or rearrangements in the chromosomes within cells that are associated with AMoL.
What is the treatment for this?
The main goal of treatment is to put the cancer into remission . That is, to a point where there are no more cancer cells in your bone marrow or blood. But this should not be confused with a cure . A cure is a state where the cancer is completely gone and has not returned.
Chemotherapy
The main treatment for acute monocytic leukemia is chemotherapy . This may include the following stages:
- Induction therapy : This treatment uses a combination of chemotherapy drugs to put AMoL into remission. Treatment usually consists of multiple sessions lasting several days, with repeat visits required.
- Consolidation therapy : In this treatment, you will continue to receive high-dose chemo to kill any remaining cancer cells. This will reduce the chance of the cancer cells coming back. Treatment usually lasts for three to four months, over a period of a few days.
- Maintenance therapy : After stabilization therapy, you may need low-dose chemo for several months or even years.
Targeted therapy
This treatment targets specific mutations or changes in cancer cells. If chemotherapy has not worked, you may need targeted therapy . Or, if there is a specific genetic mutation in the cancer cells, you may be given a targeted therapy drug that works against that mutation.
Stem cell transplant
The only way to completely cure acute monocytic leukemia is an allogeneic stem cell transplant . This may be needed after you have gone into remission. Or, if the cancer comes back after you have gone into remission, this transplant may be done. In this procedure, a doctor replaces your own stem cells with stem cells from a donor. Usually, the donor is a close blood match. Or, it can be an unrelated donor on a national or international registry.
But not everyone can have a stem cell transplant. It can also cause serious side effects. If your doctor recommends it, they will explain the pros and cons to you.
Clinical trials
A clinical trial is a study that tests the safety and effectiveness of new treatments. Depending on your diagnosis, this may be the best treatment for you. Ask your doctor if you should participate in a clinical trial.
How do you live with this condition? / What are the chances of recovery?
The outlook for someone with acute monocytic leukemia (AMoL) is generally the same as for someone with acute myeloid leukemia (AML). About 3 in 10 people with AMoL are still alive five years after diagnosis .
However, it's important to remember that these numbers don't reflect new treatments. New treatments are allowing people to live longer with AMoL. Also, your prognosis , or chance of recovery, depends on several factors. For example:
- Age : People under the age of 65 have a higher chance of recovering from AMoL.
- White blood cell count : Those with a low white blood cell count have a higher chance of recovery.
- Response to treatment : If remission occurs after initial chemotherapy (induction chemotherapy), the chances of recovery are high.
How do you take care of yourself?
Living with leukemia can be stressful . Even after you're in remission, you may still have to deal with the fear that the cancer will come back. You may also have to deal with the long-term side effects of cancer treatment. The best way to take care of yourself is to take advantage of all the resources available to you . These may include:
- Cancer survivorship programs : Connecting with other people with cancer can provide you with the support you need and help you feel like you're not alone.
- Palliative care : Palliative care helps you manage the symptoms of cancer and the side effects of cancer treatment. No matter what your prognosis, this is a valuable resource.
- Therapy : Many people with cancer experience anxiety and depression. You can get help by meeting with a mental health counselor who works with cancer survivors. A counselor can help you manage the daily stresses that come with a cancer diagnosis.
When do you need to see a doctor?
You will need to see your doctor regularly to monitor your response to treatment. They will let you know if there are any changes in your body that may indicate that the cancer is coming back. Talk to your doctor without holding anything back .
What questions should you ask the doctor?
Here are some questions you can ask your doctor:
- What treatment do I need?
- What side effects should I expect, and how can I manage them?
- Do I need to participate in a clinical trial?
- How often will I have to come for follow-up appointments?
- What resources are there that can help me?
Finally, things to remember
Finding out that you or your child has acute monocytic leukemia (AMoL) can be a shock. Blood cancers are serious conditions, and the treatments can be challenging. You will likely face several rounds of treatment over the coming days, weeks, and months.
But it's important to remember this: These treatments are helping people live longer than ever before . For some, the treatments can even completely eliminate the cancer. Ask your doctor what results you can expect. Talk to them about the pros and cons of each treatment option. They can help you cope with what's coming next.
Remember this: You are not alone in this journey. Doctors, family, and friends are all there to help you. Stay strong!
