Are your plasma cells also out of whack? Is this plasma cell leukemia dangerous?

Have you ever heard of a disease called 'Plasma Cell Leukemia'? The name may sound a little scary. But it's actually a serious, rare cancer that affects a type of cell in our body called plasma cells. Don't worry, we'll explain everything in a simple way that you can understand.

What is Plasma Cell Leukemia?

Okay, so let's first look at what Plasma Cell Leukemia is. Simply put, it's a slightly more aggressive, faster-spreading form of another type of cancer called Multiple Myeloma.

We all have a special type of cell called plasma cells in our bodies. These are the cells that produce antibodies, which are the most important things that help our bodies fight off illness, such as infection. These plasma cells are like our body's own body's security guards.

But, sometimes these plasma cells, unfortunately, start behaving abnormally, like cancer cells . That's when the problems start. Usually, in the case of 'Multiple Myeloma', these abnormal, bad plasma cells are mostly deposited in our bone marrow . Bone marrow is the soft, spongy part inside our bones.

However, in Plasma Cell Leukemia, something a little different happens. Here, those abnormal, cancerous plasma cells break out of the bone marrow, enter our blood, that is, the bloodstream, and begin to travel throughout the body. Imagine, what happens here is like a few dangerous criminals escaping from prison and causing trouble throughout the city.

This is the main difference between 'Multiple Myeloma' and 'Plasma Cell Leukemia'. This is why Plasma Cell Leukemia (PCL) is considered a more aggressive and rapidly spreading disease.

Who is most likely to get this disease?

Now you may be wondering who is most likely to develop this condition called Plasma Cell Leukemia. As is generally seen, this disease is more common among men between the ages of 55 and 65. Also, some studies have found that there is a higher incidence of this disease among Black people .

But the most important thing is that, overall, this is a very rare condition . In fact, plasma cell leukemia (PCL) is the rarest form of the cancer group called multiple myeloma. It is reported to account for a very small percentage, about 2% to 3% of all plasma cell cancers. So it is not a disease that many people get.

There are treatments for this. These treatments can help control the growth of the cancer, reduce symptoms and make life easier, and even extend the time you can live to some extent. However, in most cases, it is difficult to completely cure this disease. But it is not good to give up hope. Because of new treatments, doctors have now been able to extend the life of patients with Plasma Cell Leukemia. However, there is much more to be discovered in this field through further research.

Are there types of plasma cell leukemia (PCL)?

Yes, there are two main types of plasma cell leukemia (PCL). Let's learn about both of them.

• Primary PCL: This is when a person develops plasma cell leukemia (PCL) without having previously had multiple myeloma. This means that the abnormal plasma cells are circulating in the blood at the time of diagnosis. This is what is seen in the majority of PCL patients ( approximately 60%) . About one in a million people in the general population are affected by this primary PCL condition.

• Secondary PCL: This occurs when a person already has multiple myeloma, but over time, the disease becomes more severe and transforms into plasma cell leukemia (PCL). This means that PCL develops as a severe form of myeloma. Research suggests that between 0.5% and 4% of multiple myeloma patients develop secondary PCL. About 40% of PCL patients fall into this category.

What are the symptoms of plasma cell leukemia (PCL)?

The symptoms of plasma cell leukemia (PCL) can vary from person to person. However, there are some common symptoms that we will look at:

• Fatigue: Feeling tired all the time, feeling like you can't do anything.
• Anemia: Simply put, this is a lack of blood. The body becomes pale, you get tired, and you feel tired even when climbing stairs. This is because the formation of healthy red blood cells is inhibited by those bad plasma cells.
• Increased bleeding: Even a small wound may take a long time to stop bleeding, possibly causing bleeding gums or bruising on the skin.
• Bone pain: Bone pain can occur, especially in areas like the spine, ribs, and hips.
• Bone fracture: Sometimes, bones become so weak that a bone can break even with a simple fall, even without any major injury.
• Increased calcium levels in the blood (Hypercalcemia):This is a somewhat serious condition. When calcium levels in the blood increase, symptoms such as nausea, vomiting, dry mouth, confusion, and excessive thirst may occur.
• Frequent infections: As the body's immunity decreases, illnesses like colds and flu occur frequently, and once they do occur, they take longer to recover.
• Kidney damage: The proteins produced by those abnormal plasma cells can damage the kidneys.

If you have one or more of these symptoms, don't panic, as they can be symptoms of other conditions. However, if these symptoms persist, it's always a good idea to see a doctor for advice.

What causes plasma cell leukemia (PCL)?

In fact, researchers have not yet discovered the exact cause of plasma cell leukemia (PCL). But what is known is that it is caused by acquired genetic changes in the genes of plasma cells as they develop. Simply put, there are errors in the DNA of plasma cells.

However, why these genetic changes occur is still a mystery . It is difficult to say exactly what environmental factors, lifestyle influences, or other causes contribute to it. Since this is a rare disease, researching it is also a bit challenging.

How is plasma cell leukemia (PCL) diagnosed?

To know for sure if someone has plasma cell leukemia (PCL), a doctor will need to perform several tests.

1. Blood test: This is the most basic step. A sample of your blood is taken and the number of abnormal plasma cells in it is measured. In PCL, more than 5% of your total white blood cells are made up of these abnormal plasma cells.

2. Bone marrow biopsy: This involves taking a small sample of your bone marrow and checking it for abnormal plasma cells. This is usually done from the hip bone. Although it can be a little painful, it is very important for diagnosis.

3. Imaging tests: Tests such as a CT scan (Computed Tomography scan) or MRI (Magnetic Resonance Imaging) are also performed to see if the disease has damaged the bones.

Only after doing all these tests can the doctor tell you exactly whether you have PCL or not, and if so, what the condition is.

How is plasma cell leukemia (PCL) treated?

Plasma cell leukemia (PCL) is treated on an individual basis. This means that not everyone is given the same treatment. The medical team will carefully study your condition and recommend the treatment method or combination of treatments that is most suitable for you.

The same treatments are usually used for PCL as for multiple myeloma. Here are some of them:

• Chemotherapy: This involves giving powerful drugs to kill cancer cells. Examples include `Doxorubicin (Adriamycin®), `Cisplatin` and `Cyclophosphamide (Cytoxan®).`
• Immunotherapy: This involves stimulating your own immune system to fight cancer cells. This includes newer treatments such as monoclonal antibodies (e.g., Daratumumab (Darzalex®)), bispecific antibodies (e.g., Teclistamab (Tecvayli®)), and chimeric antigen receptor (CAR) T-cell therapy.
• Targeted therapy: These drugs work by targeting specific molecules that help cancer cells grow and survive, stopping them from working. These include proteasome inhibitors (e.g., Bortezomib (Velcade®), Carfilzomib (Kyprolis®), Ixazomib (Ninlaro®)) and immunomodulators (e.g., Lenalidomide (Revlimid®), Pomalidomide (Pomalyst®).
• Autologous Stem Cell Transplant: This involves transplanting healthy stem cells taken from the patient themselves after chemotherapy. However, not everyone is eligible for this treatment. The doctor decides.

In addition to these treatments, your doctor may also recommend palliative care services to help manage your symptoms, reduce pain, and provide you with mental and physical comfort during this difficult journey.

Important: Reading about these treatments and medications may make you feel a little confused. However, all of this is decided by your medical team. They will explain everything to you. Don't be afraid to ask them any questions you have.

What is the life expectancy of people with plasma cell leukemia (PCL)?

This is a really difficult topic to talk about. Plasma cell leukemia (PCL) is a very aggressive, rapidly spreading disease, and is often fatal . Less than 10% of people with this cancer live more than five years after diagnosis. In general, people with primary PCL live slightly longer than those with secondary PCL.

Life expectancy depends on many things, including the severity of the disease, the type of treatment you receive, and how your body responds to those treatments.

Those who qualify for a stem cell transplant are said to live an average of three to four years . However, some people may live even longer. One study reported that a PCL patient had been in remission for nine years before the disease recurred.

Today, the lifespan of these patients has been extended by a small amount compared to a few decades ago. Even though it's a small improvement, it's still a big deal. Researchers are still working on this with great interest.

Can plasma cell leukemia (PCL) be prevented?

Unfortunately, there is no way to prevent plasma cell leukemia (PCL). Because we cannot control the genetic changes that cause it, it is also very rare, making it difficult to study and find ways to prevent it. However, researchers are continuing to find ways to detect the disease early.

How do I take care of myself?

When you are diagnosed with a disease like plasma cell leukemia (PCL), it is normal to feel uncertain about the future, and to experience a range of emotions, including fear, anger, sadness, frustration, and guilt. There is nothing wrong with feeling these emotions. The most important thing is to talk about your feelings with someone. Talk to someone you trust, a family member, a friend, or your doctor about support services. They can help you maintain your quality of life after your diagnosis and during treatment.

When should I see the doctor?

You will stay in close contact with your medical team throughout your treatment. However, if you develop new symptoms or if your symptoms seem to be getting worse, you should let your doctor know right away.

What questions should I ask my doctor?

If you have plasma cell leukemia (PCL), you may have many questions. Here are some important questions to ask your doctor:

• How far has the cancer spread? (How advanced is the cancer?)
• What are my treatment options?
• Am I eligible for a stem cell transplant?
• How long can I live with treatment?
• What resources are available to me?

Any cancer is a life-changing event. But when you have a rare, serious disease like plasma cell leukemia (PCL), it can be very lonely and overwhelming. You may feel like no one understands what you're going through. If possible, join a support group.. Then you can meet and talk to others who are going through the same experiences as you. Trust your loved ones, your medical team. They are all there to help you, to support you in maintaining your quality of life after diagnosis and during treatment. You don't have to go through this journey alone.

Take-Home Message

Plasma Cell Leukemia (PCL) is a severe, rare form of multiple myeloma. In this type of cancer, abnormal plasma cells circulate in the blood. Symptoms can vary, including fatigue, anemia, and bone pain. Although genetic changes are thought to be the cause, the exact cause is not known.

Diagnosis is made through blood tests, bone marrow biopsy, and imaging tests. Treatment options include chemotherapy, immunotherapy, targeted therapy, and stem cell transplant.

Although this is a serious disease, life expectancy has increased somewhat with new treatments. The most important thing is to seek medical advice early if you have symptoms, get proper treatment, and stay mentally strong. Your medical team and loved ones will be a great source of strength for you on this journey.
