Mantle Cell Lymphoma: Causes, Symptoms, and Treatment

What kind of doctor treats Mantle Cell Lymphoma?
A hematologist, a doctor who treats blood and lymph disorders, or a medical oncologist, a doctor who treats cancer with medicine, usually leads care for mantle cell lymphoma. Care often involves a team of cancer specialists. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What is mantle cell lymphoma?
Mantle cell lymphoma (MCL) is a type of non-Hodgkin lymphoma, which is a cancer of the lymphatic system. The lymphatic system helps protect the body against infection and disease. MCL starts in B cells, a type of white blood cell, in an area of a lymph node called the mantle zone. It is uncommon, making up about 5% of non-Hodgkin lymphomas in the United States. It mostly affects older adults, and about three-quarters of people with it are male.
Symptoms
Many people have no symptoms early on. Possible signs include:
- Swollen lymph nodes, often painless, that do not go away. Lymph nodes are small structures that filter fluid in the body.
- Fever, weight loss without trying, and sweating at night.
- Loss of appetite, bloating, or belly pain, which can come from an enlarged spleen or liver.
- Tiredness, pale skin, easy bruising or bleeding, and more infections, when the lymphoma crowds the bone marrow and blood cell counts drop.
- Growths called polyps in the intestines in some people.
In rare cases, MCL spreads to the brain and spinal cord. This can cause headaches, weakness, confusion, personality changes, or seizures.
Causes and who gets it
The exact cause of MCL is unknown. Almost all people with MCL have an acquired gene change called t(11;14), in which pieces of chromosomes 11 and 14 trade places. This change leads to too much of a protein called cyclin D1, which helps control cell growth. Extra cyclin D1 alone is not enough to cause MCL. Researchers are studying other possible factors, such as family history, inflammation, and infection. Many people are diagnosed at around age 60 to 70, and most already have advanced disease (stage III or IV) when found.
How doctors diagnose it
A doctor asks about your health and feels the lymph nodes in areas such as the neck, underarms, and groin. To confirm MCL, a biopsy must be done. Lab tests on the sample can look for the 11;14 gene change and the cyclin D1 protein. Blood tests check blood counts and how well organs work. Scans such as CT, MRI, and PET show how far the lymphoma has spread.
Treatment
Treatment depends on the stage, the subtype, symptoms, age, and general health. Some people with a slow-growing form and no symptoms may wait before treatment, with frequent checkups. This is called watchful waiting. People with a more aggressive form often start treatment near the time of diagnosis. First treatment usually combines chemotherapy, which uses drugs that kill cancer cells, with immunotherapy, which uses drugs that help the immune system attack cancer. Targeted drugs are sometimes added. Rituximab is one example of immunotherapy. Younger, fit people may get a stem cell transplant using their own stem cells, collected before high-dose chemotherapy. Newer studies suggest most people can avoid a transplant when targeted drugs called BTK inhibitors are used. After first treatment, maintenance therapy with rituximab for at least 2 to 3 years is the standard of care. If MCL returns, options include targeted drugs called BTK inhibitors and CAR T-cell therapy, which reprograms a person's own T cells to attack cancer. MCL responds well to treatment, but in most cases it cannot be cured. Before starting drug treatment, doctors screen for hepatitis B, hepatitis C, and HIV. Cancer drugs can also harm healthy cells and cause side effects, so ask your doctor what to expect.
When to see a doctor
See a doctor if you have swollen lymph nodes that do not go away, repeated fevers, night sweats, or weight loss without trying. Call 911 or go to the emergency room if you faint, pass out, have trouble breathing, have chest pain, have a seizure or sudden confusion, or have bleeding that will not stop.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. Either can check new lymph node swelling, order first blood tests, and refer you to a hematologist or oncologist. They can also help coordinate your care team and follow up between cancer visits.
Common questions
Can mantle cell lymphoma be cured?
In most cases, no. It can respond well to treatment, but it is expected to relapse (come back) eventually. Many older patients, though, stay in remission for the rest of their lives.
Is mantle cell lymphoma fast or slow growing?
It can be either. Experts classify it as aggressive, but it has some features of slow-growing lymphoma.
Is mantle cell lymphoma the same as Hodgkin lymphoma?
No, MCL is a non-Hodgkin lymphoma. Hodgkin lymphoma is typically marked by a special cancer cell called a Reed-Sternberg cell.
Who is most likely to get mantle cell lymphoma?
Older adults, and men more than women, are most likely to get it. Many people are diagnosed at around age 60 to 70.
