Quick Answer: What are lymphoproliferative disorders?
Lymphoproliferative disorders are a broad group of rare diseases that happen when lymphocytes do not work as they should. They are commonly organized into immunologic disorders, which affect immune-system responses, and lymphoid blood cancers, which involve abnormal B cells, T cells, or natural killer cells. [1]
The right diagnosis and treatment depend on the specific disorder.
What the research says
Post-transplant lymphoproliferative disease (PTLD) was uncommon overall but varied widely by transplant type and tended to appear years after transplant. In a cohort of 5,365 solid-organ transplant recipients at two UK centres, 142 developed PTLD over a median follow-up of 7.7 years. The five-year cumulative incidence was 18% after multivisceral transplant and 1% to 3% after other transplant types; the 20-year cumulative incidence was 2% to 3% after liver or heart transplant and 10% after kidney transplant. Among 90 patients with monomorphic PTLD (diffuse large B-cell lymphoma), 66 received first-line rituximab alone and 24 rituximab plus chemotherapy, and up-front rituximab alone did not appear to compromise overall survival (Santarsieri et al., Br J Haematol, 2022). [2]
In autoimmune lymphoproliferative syndrome (ALPS), bone marrow changes can mimic lymphoma, so diagnosis needs more than one type of test. Researchers reviewed 31 bone marrow biopsies from a cohort of 240 patients with germline FAS mutations. Bone marrow lymphocytosis was the most common finding (74%, 23 of 31), and in four cases prominent T-cell aggregates diffusely replaced the marrow space. No clonal B or T cells were found by polymerase chain reaction, and classical Hodgkin lymphoma was identified in 3 cases. The authors recommend combining clinical, histological, immunohistochemical and other tests to avoid a diagnostic pitfall (Xie et al., Haematologica, 2017). [3]
What do lymphoproliferative disorders affect?
Lymphocytes help the immune system respond to intruders such as cancer, viruses, and bacteria. LPDs happen when these cells do not work as they should. In some disorders, lymphocytes build up in places such as the lymph nodes, spleen, or liver. In others, abnormal cells multiply in the bone marrow and blood. [1]
There are more than a dozen different diseases in the LPD group. That is why the term describes a category rather than one single illness. Two people with an LPD may have different symptoms, tests, treatments, and outlooks. [1]
What are the two main groups of LPDs?
LPDs are broadly divided into immunologic disorders and lymphoid blood cancers. The first group affects how the immune system reacts to intruders. The second group includes abnormal lymphocytes that multiply in the bone marrow and blood. [1]
Group | What it involves | Examples |
Immunologic disorders | Conditions that affect how the immune system reacts. | X-linked lymphoproliferative disorder, autoimmune lymphoproliferative syndrome, and post-transplant lymphoproliferative disorders. |
Lymphoid blood cancers | Abnormal B cells, T cells, or natural killer cells multiply in the bone marrow and blood. | B-cell and T-cell lymphomas, lymphocytic leukemias, and NK-cell lymphocytic disorders. |
What are immunologic lymphoproliferative disorders?
X-linked lymphoproliferative disorder, or XLP, can cause an unusually severe response to Epstein-Barr virus that may lead to lymphoma. Autoimmune lymphoproliferative syndrome, or ALPS, involves large numbers of lymphocytes building up in the lymph nodes, spleen, and liver, which can make these organs larger. [1]
Post-transplant lymphoproliferative disorders, or PTLDs, are described as rare but serious complications of solid-organ transplants or donated stem-cell transplants. They can occur when B cells associated with Epstein-Barr virus are involved. [1]
What are lymphoid blood cancers?
Lymphoid blood cancers happen when white blood cells change and abnormal cells multiply in the bone marrow and blood. The affected cells may be B cells, T cells, or natural killer cells. Some of these diseases are curable, but they are serious illnesses that may be life-threatening. [1]
The B-cell group includes non-Hodgkin lymphomas such as diffuse large B-cell lymphoma, follicular lymphoma, and mantle cell lymphoma. It also includes B-cell lymphocytic leukemias such as chronic lymphocytic leukemia, B-cell prolymphocytic leukemia, and hairy cell leukemia.
T-cell disorders can be systemic, affecting lymph nodes, the spleen, bone marrow, blood, and other organs, or cutaneous, mainly affecting the skin. Examples include peripheral T-cell lymphoma, angioimmunoblastic T-cell lymphoma, anaplastic large cell lymphoma, mycosis fungoides, and Sézary syndrome. [1]
NK-cell lymphocytic disorders are very rare. Examples include extranodal NK/T-cell lymphoma of the nasal type, aggressive NK-cell leukemia, and NK-cell large granular lymphocytic leukemia. [1]
What are the symptoms of lymphoproliferative disorders?
LPD symptoms vary widely because the group includes many different conditions. Common symptoms include drenching night sweats, enlarged or swollen lymph nodes, an enlarged liver or spleen, unusual bleeding or bruising, fatigue, fever, frequent viral infections, loss of appetite, and unexplained weight loss. [1]
A symptom does not identify a particular LPD by itself. The same symptom can occur with different conditions, so a healthcare provider considers the full pattern, medical history, physical findings, and test results.
Symptom pattern | What a person may notice |
Lymphatic or abdominal changes | Swollen lymph nodes or a liver or spleen that is larger than usual. |
Whole-body symptoms | Fatigue, fever, drenching night sweats, loss of appetite, or unexplained weight loss. |
Blood or immune changes | Unusual bleeding or bruising, or frequent viral infections. |
What causes lymphoproliferative disorders?
There is no single cause for most LPDs. Potential causes include infections such as Epstein-Barr virus or H. pylori, certain autoimmune diseases, immunosuppressant medicines, and genetic mutations. [1]
Some rare inherited mutations can cause an LPD. For example, XLP involves genetic mutations associated with an unusually severe reaction to Epstein-Barr virus. Genetic mutations that affect white blood cell growth can also play a role in lymphoma and leukemia. [1]
A possible cause or risk factor does not confirm that someone has an LPD. A provider uses the person’s history, symptoms, examination, and tests to identify what is happening.
Possible contributor | How it may relate to LPDs |
Infection | Epstein-Barr virus or H. pylori may cause some types of LPDs. |
Autoimmune disease | Rheumatoid arthritis or lupus may cause some types of marginal zone lymphomas. |
Medication | Immunosuppressant medicines may lead to hepatosplenic T-cell lymphoma. |
Genetic mutation | Rare inherited mutations or mutations affecting white blood cell growth may play a role in some disorders. |
How are lymphoproliferative disorders diagnosed?
Diagnosis focuses on finding which disorder is causing the symptoms. A provider may ask about swollen lymph nodes, signs that the liver or spleen is enlarged, and medical history. The testing plan depends on the suspected condition.
A bone marrow biopsy may be used to look for blood cancers such as leukemia or lymphoma. Blood tests may include a complete blood count, comprehensive metabolic panel, Epstein-Barr antibody test, hepatitis test, HIV test, or lactate dehydrogenase test. [1]
Imaging may include computed tomography or positron emission tomography scans. Flow cytometry may be ordered to help diagnose specific disorders. [1]
Evaluation step | What it may help assess |
Medical history and examination | Symptoms, swollen lymph nodes, and signs of an enlarged liver or spleen. |
Bone marrow biopsy | Signs of a blood cancer such as leukemia or lymphoma. |
Blood tests | Blood-cell patterns, organ-related chemistry, infection-related antibodies, hepatitis, HIV, or LDH. |
Imaging tests | Findings on CT or PET scans. |
Flow cytometry | Specific disorders involving blood cells. |
How are lymphoproliferative disorders treated?
Treatment depends on the specific disorder. When an LPD is a type of leukemia or lymphoma, possible treatments include chemotherapy, immunotherapy, radiation therapy, stem cell or bone marrow transplant, and targeted therapy. [1]
Treatment options are not the same for every LPD. The care team uses the diagnosis and other relevant factors to explain which approach may be appropriate.
Some LPDs are treated with the goal of cure. Others may enter remission, which means symptoms are absent and tests do not find signs or evidence of disease. Some disorders can return months or years after treatment. [1]
Treatment category | Examples of where it may fit |
Chemotherapy | A listed treatment for some leukemia or lymphoma-related LPDs. |
Immunotherapy | A listed treatment option for some LPDs. |
Radiation therapy | A listed treatment option for some LPDs. |
Stem cell or bone marrow transplant | May be used in selected disorders; a stem cell transplant may cure XLP. |
Targeted therapy | A listed treatment option for some LPDs. |
What is the outlook for a lymphoproliferative disorder?
Outlook depends on the type of LPD and many other factors. Certain lymphomas, including large B-cell lymphoma, Burkitt lymphoma, and Hodgkin lymphoma, may be cured with chemo-immunotherapy. A stem cell transplant may cure XLP. [1]
In some cases, treatment puts a lymphoma into remission rather than curing the disease. Some LPDs can return months or years after treatment. A healthcare provider who knows the diagnosis and situation is the best person to explain what to expect. [1]
How can someone live with an LPD?
LPDs are serious illnesses, but treatments may ease symptoms and may cure some conditions. Palliative care can help manage symptoms and treatment side effects. A nutritionist may offer suggestions when illness or treatment affects appetite. [1]
Light exercise may help with stress, but a person should talk with a healthcare provider before starting a new exercise program. If illness or treatment weakens the immune system, ask the care team how to reduce the risk of viral infections. [1]
People receiving treatment should ask their healthcare provider which body changes may signal that the condition is getting worse. A fever that does not go away is one example. Knowing what to watch for can clarify when to contact the care team.
When should you contact a healthcare provider?
Contact a healthcare provider about symptoms such as swollen lymph nodes, an enlarged liver or spleen, fatigue, fever, drenching night sweats, unusual bleeding or bruising, frequent viral infections, loss of appetite, or unexplained weight loss. These symptoms can have different causes, and professional evaluation is needed to identify the reason.
If you are already receiving treatment for an LPD, ask the care team which changes should prompt a call. A fever that does not go away or other changes identified by the provider may need timely attention.
What questions should you ask the care team about lymphoproliferative disorders?
Question | Why it may help |
Which LPD is being considered? | The group includes many different disorders with different symptoms and treatments. |
Which tests are needed? | Blood tests, bone marrow biopsy, imaging, and flow cytometry may be used for different diagnostic questions. |
What do the results show? | Test results help classify the disorder and guide care. |
What treatment options apply to this disorder? | Treatment depends on the specific condition. |
What does remission mean in this case? | Remission means symptoms are absent and tests find no signs or evidence of disease. |
Which changes should prompt a call? | The provider can explain symptoms or changes that may signal worsening disease. |
Can palliative care or nutrition support help? | These services may help with symptoms, side effects, and appetite-related concerns. |
Conclusion: LPDs are a group, not one single diagnosis
Lymphoproliferative disorders include immunologic conditions and lymphoid blood cancers involving lymphocytes. Symptoms may include swollen lymph nodes, an enlarged liver or spleen, fatigue, fever, night sweats, unusual bleeding or bruising, frequent viral infections, loss of appetite, and unexplained weight loss. [1]
Because the category contains many different diseases, diagnosis depends on the specific pattern of symptoms, medical history, examination, and test results. Treatment and outlook also vary. If a provider uses the term LPD, ask which disorder is involved, what the tests show, how treatment is chosen, and which changes should prompt a call. [1]
