Lymphoplasmacytic Lymphoma is a very rare cancer and can affect different parts of your body. No two people with LPL will have the same experience. For this reason, we do not know the typical signs and symptoms, or best treatment options for LPL.
The information on this webpage is based from case studies reported in medical literature. However, it is important for you to understand that your symptoms, tests and treatment may differ from what is on this page, based on your individual circumstances.
Speak with your haematologist or oncologist about what to expect in your individual circumstance.
Overview of Lymphoplasmacytic Lymphoma (LPL)
Lymphoplasmacytic Lymphoma (LPL) is an umbrella term for several different types of very rare cancers that begin in B-cell lymphocytes. The most common subtype of LPL is Waldenstroms Macroglobulinemia and this subtype is discussed separately on another page. You can find the link here.
About B-cell Lymphocytes
B-cell lymphocytes are a type of white blood cell that support our immune system by fighting infection and disease. The most mature form of B-cell lymphocyte is called a plasma cell, and these cells make antibodies that stick to damaged or diseased cells and call other immune cells to the disease cells to repair or destroy it.
What happens in LPL?
LPL results in cancerous small B-cell lymphocytes, plasmacytoid lymphocytes and plasma cells invading your bone marrow. These different cells are all B-cell lymphocytes at different levels of development. The plasmacytoid lymphocyte is a cell changing from a small lymphocyte to a plasma cell.
Once in the bone marrow, these cells produce too much of either IgA, IgG or IgM antibodies. As a result of the extra cells and antibodies in the bone marrow, you may not be able to make enough of your health blood cells such as red cells, platelets and other white cells like neutrophils.
The cancerous cells and extra antibodies can also invade your lymph nodes, and organs within your lymphatic system such as your spleen, causing your lymph nodes and/or spleen to become enlarged. In some rarer cases LPL can invade “extra-nodal” areas of your body – meaning parts of your body other than your lymphatic system such as your:
- respiratory tract (lungs and airways)
- gut (stomach and bowels)
- bones
- kidney
- lining of your brain (meninges).
Non-Waldenstroms LPL subtypes
There are different subtypes of Non-Waldenstroms Lymphoplasmacytic Lymphoma, including:
- *LPL with IgG proliferation
- *LPL with IgA proliferation
- *LPL with Light chain proliferation
- **LPL non-secretory.
**Rarely these lymphoma cells may be in your bone marrow but produce no paraprotein – this is called non-secretory disease.
About Lymphoplasmacytic Lymphoma (LPL)
LPL is an indolent lymphoma, which means it is a very slow growing cancer, that may go through periods where it “sleeps” and other periods where it wakes up and actively produces too much antibody. It tends to be found more commonly in women than men, though men can develop it too. Most people diagnosed with LPL are around the ages of 65-69 years.
Not everyone with LPL will need to start treatment straight away because it is such a sleepy lymphoma. However, about 8 out of 10 people (80%) with LPL, will need to start treatment within about 6 months of being diagnosed.
Non-Waldenstrom’s LPL often have features that are similar to different subtypes of lymphoma or other blood cancers. This can make it very tricky to get an absolute diagnosis of any particular subtype.
Multidisciplinary meetings
With LPL being so rare, it is always a good idea to get opinions from other haematologists and members of the health care team for advice. You can ask your haematologist to present your case at a national lymphoma multidisciplinary meeting to get opinions from others, before making a final decision on treatment.
Other blood cancers LPL can mimic
LPL often looks and behaves in the same as other subtypes of lymphoma and other blood cancers. As such, your haematologist will consider all of these when examining your lymphoma cells. Considering and testing all possibilities can take some time. Some of the other subtypes of lymphoma that LPL can mimic include:
Antibodies
Antibodies are made by our Plasma Cells – the most mature form of B-cell Lymphocytes. They are important proteins that help our immune system recognise and fight germs, infections and diseased or damaged cells. Antibody proteins are called immunoglobulins which is often shortened to Ig.
Antibodies help our immune system to fight infection and disease by seeking out germs, diseased and damaged cells and sticking to them. Once stuck, the antibody sends out chemical messages to other immune cells to tell them to come and get rid of the cell. Some antibodies can also directly attack the diseased cells. However, they are very specific and each antibody will only recognise and stick to one receptor on one type of cell.
Kappa, Lambda, Heavy and Light Chains
There are other terms you might hear your doctor talk about when talking about your antibodies. These include kappa or lambda and heavy and light chains.
If you look at the picture of antibody here, you will see it looks like the letter Y with extra bits, one on either side at the top. The blue area is referred to as the heavy chain and the purple area is referred to as the light chain. The heavy and light chains are separate proteins that link up to make the immunoglobulin.
Heavy chains can be either A, D, E, G or M (which makes it an IgA, IgD, IgE, IgG or IgM) and light chains can be kappa or lambda. The antibody has two heavy chains and two light chains. The two heavy chains are always the same and the two light chains are always the same. For example, you:
- can have an IgG antibody with kappa light chains or IgG antibody with lambda light chains
- cannot have an IgG antibody with kappa and lambda light chains.
Both kappa and lambda can be found on any type of immunoglobulin (antibody). In some cases, your body might make too many light chains for the number of heavy chains, so you will have extra light chains in your blood and bone marrow – These are called “free” light chains.

Symptoms of Lymphoplasmacytic Lymphoma (LPL)
Due to the slow growing nature of LPL, you may not have symptoms when you are diagnosed. However, many people will experience symptoms at some point.
Common symptoms you may get with LPL include:
- Swollen lymph nodes
- An enlarged spleen that can cause a feeling of fullness in your tummy even if you haven’t eaten much.
- Pain or discomfort in the left side of your abdomen or chest
- Fatigue and dizziness.
- Changes to blood counts including low red cells (anemia) or platelets (thrombocytopenia), high lymphocytes and high lactate dehydrogenase (LDH).
Other symptoms of LPL
While the above symptoms may affect anyone with LPL, some symptoms may be related to the part of your body the LPL is growing. As an example, if the LPL is growing in your stomach or bowels you may have:
- indigestion or heartburn
- changes to your appetite
- weight loss
- vomiting
- bloating
- bleeding when you go to the toilet
- B-symptoms.
Diagnosis and Staging of LPL
Your doctor may suspect you have LPL after you have a blood test. But they will need to do more tests to confirm this, and look at what parts of your body are affected. Some of these tests will include:
- More blood tests
- Urine (wee) tests
- Bone marrow biopsy
- Computed tomography (CT) scan
- PET scan
- Tests on your heart, liver and kidneys
Your treating heamatologist or oncologist will work out the best tests for you based on:
- your symptoms and how the LPL is affecting your organs
- the location of your LPL
- your blood results
- IgG, IgA or IgM antibody levels.
You may have one or more tests from the above list, or something altogether different depending on your individual circumstance.
Treatment
You may not need to have any treatment for your LPL, if you are not getting symptoms and the LPL is not actively growing. But if you do not need actively treatment, you will still me monitored by your haematologist. During this time of monitoring you will continue to have blood tests and physical examinations. This monitoring period is called Watch & Wait (or active monitoring). This way if there are any changes to how your LPL is behaivng or affecting you, the haematologist can pick it up early and recommend treatment.
You may need to start treatment if your:
- symptoms are troubling you
- antibody levels are too high
- heamoglobin or platelets (blood cells) are too low
- lactate dehydrogenase (LDH blood test) is too high
- other concerns as per your haematologist.
Before you start treatment
Before you start treatment, let your doctor know if you are hoping to have children in the future. Many anti-cancer treatments can affect your fertility, or cause harm to unborn babies, so it is important to talk to your doctor about these things. In some cases, they may be able to organise some extra treatments to increase your chances of getting pregnant, or getting someone else pregnant in the future.
There are also other things you should talk to your doctor about, but it can be hard to know what questions to ask when you are first diagnosed. To help guide your conversation we have put together some questions you may like to ask. Click on the link below to download our Questions to ask your doctor.
Treatment options
The treatment options you are offered will depend on your:
- location of your LPL
- symptoms and how the LPL is affecting your body
- age and overall health
- overall health and any other illnesses you may have or medications you are taking
- personal preferences after you have all the information you need.
However, some treatment options may include any of the following.
Follow-up care
Once treatment has completed, post treatment staging scans are done to review how well the treatment has worked. The scans will show the doctor if there has been a:
- Complete response (CR or no signs of lymphoma remain) or a
- Partial response (PR or there is still lymphoma present, but it has reduced in size)
If all goes well regular follow-up appointments will be made for every 3-6 months to monitor the below:
- Review the effectiveness of the treatment
- Monitor any ongoing side effects from the treatment
- Monitor for any late effects from treatment over time
- Monitor signs of the lymphoma relapsing
These appointments are also important so that the patient can raise any concerns that they may need to discuss with the medical team. A physical examination and blood tests are also standard tests for these appointments. Apart from immediately after treatment to review how the treatment has worked, scans are not usually done unless there is a reason for them. For some patient’s appointments may become less frequent over time.
Prognosis for Lymphoplasmacytic Lymphoma (LPL)
Due to being so rare, the overall prognosis for LPL is not known, though it is thought to be similar to those with LPL subtype Waldenstroms Macroglobulinemia.
Like most indolent subtypes of lymphoma, LPL cannot be cured. Instead, if you need treatment the aim will not be to cure but to manage the disease. This means keeping your antibody levels at a level that does not cause damage to your organs or cause you to get uncomfortable symptoms.
Most people get a really good response from treatment, and go into remission, however because we cannot cure LPL, it is common for it to come back (relapse) and for you to need more treatment at a later time. For some people, it may be months, and for others it could be years before you need more treatment.
Relapsed or refractory LPL
Some people with lymphoma who get a good response from treatment may relapse, which is when the lymphoma comes back after a time of remission. In rare cases your lymphoma may not respond to the first-line treatment (refractory). If you have relapsed or have a refractory LPL, you may need to start treatment again, or start a new treatment. This next lot of treatment will be called second-line treatment.
Before you start the next treatment, your doctor will consider several things while trying to find the best treatment for you including:
- how long it has been since your last treatment and how well it worked for you
- how long you have been in remission for
- side-effects you had with previous treatments
- your age and general well-being
- your preferences once you have all the right information to make the best choice for you.
Depending on your individual circumstance. You may be offered the same treatment you had before if it worked well, and you have been in remission for several years. You may also be offered one of the other treatments listed above. If you need to start second-line treatment, it is a good idea to ask your doctor about any clinical trials you may be eligible for.
Clinical Trials – Treatments under investigation
There are new clinical trials starting all the time and it is a good idea to keep up to date with what new treatments are being tested to improve the treatment, or quality of life for people with WM. If you are interested in participating in a clinical trial, you can ask your doctor if you meet the inclusion criteria for the study.
ClinTrial Refer is a good website that lists the different clinical trials available. You can access it by clicking here, and type in the search bar what condition you have that you would like to find a clinical trial for such as “B-cell lymphoma”.
Health and wellbeing
A healthy lifestyle, or some positive lifestyle changes after treatment can be a great help after you finish treatment. Making small changes such as eating well and increasing your overall fitness can improve your health and wellbeing and help your body to recover. There are many self-care strategies that can help during your recovery. Click on the link for more tips on living well.
