General Information About Adult Non-Hodgkin Lymphoma

Adult non-Hodgkin lymphoma is a disease in which malignant (cancer) cells form in the lymph system.

Non-Hodgkin lymphoma is a type of cancer that forms in the lymph system, which is part of the body's immune system. The immune system protects the body from foreign substances, infection, and diseases. The lymph system is made up of the following:

Lymph system; drawing shows the lymph vessels and lymph organs including the lymph nodes, tonsils, thymus, spleen, and bone marrow.  One inset shows the inside structure of a lymph node and the attached lymph vessels with arrows showing how the lymph (clear fluid) moves into and out of the lymph node. Another inset shows a close up of bone marrow with blood cells.Anatomy of the lymph system, showing the lymph vessels and lymph organs including lymph nodes, tonsils, thymus, spleen, and bone marrow. Lymph (clear fluid) and lymphocytes travel through the lymph vessels and into the lymph nodes where the lymphocytes destroy harmful substances. The lymph enters the blood through a large vein near the heart.

Lymph tissue is also found in other parts of the body such as the stomach, thyroid gland, brain, and skin. Cancer can spread to the liver and lungs.

Non-Hodgkin lymphoma during pregnancy is rare. Non-Hodgkin lymphoma in pregnant women is the same as the disease in nonpregnant women of childbearing age. However, treatment is different for pregnant women. This summary includes information on the treatment of non-Hodgkin lymphoma during pregnancy (see the Treatment Options for Non-Hodgkin Lymphoma During Pregnancy section for more information).

Non-Hodgkin lymphoma can occur in both adults and children. Treatment for adults is different than treatment for children. (See the PDQ summary on Childhood Non-Hodgkin Lymphoma Treatment for more information.)

The major types of lymphoma are Hodgkin lymphoma and non-Hodgkin lymphoma.

Lymphomas are divided into two general types: Hodgkin lymphoma and non-Hodgkin lymphoma. This summary is about the treatment of adult non-Hodgkin lymphoma.

For information about certain types of lymphoma, see the following PDQ summaries:

Non-Hodgkin lymphoma can be indolent or aggressive.

Non-Hodgkin lymphoma grows and spreads at different rates and can be indolent or aggressive. Indolent lymphoma tends to grow and spread slowly, and has few signs and symptoms. Aggressive lymphoma grows and spreads quickly, and has signs and symptoms that can be severe. The treatments for indolent and aggressive lymphoma are different.

This summary is about the following types of non-Hodgkin lymphoma:

Indolent non-Hodgkin lymphomas

Aggressive non-Hodgkin lymphomas

Age, gender, and a weakened immune system can affect the risk of adult non-Hodgkin lymphoma.

Anything that increases your risk of getting a disease is called a risk factor. Having a risk factor does not mean that you will get cancer; not having risk factors doesn’t mean that you will not get cancer. Talk with your doctor if you think you may be at risk.

These and other risk factors may increase the risk of certain types of adult non-Hodgkin lymphoma:

Signs and symptoms of adult non-Hodgkin lymphoma include swelling in the lymph nodes, fever, night sweats, weight loss, and fatigue.

These signs and symptoms may be caused by adult non-Hodgkin lymphoma or by other conditions. Check with your doctor if you have any of the following:

When fever, night sweats, and weight loss occur together, this group of symptoms is called B symptoms.

Other signs and symptoms of adult non-Hodgkin lymphoma may occur and depend on the following:

Tests that examine the body and lymph system are used to help detect (find) and diagnose adult non-Hodgkin lymphoma.

The following tests and procedures may be used:

If cancer is found, the following tests may be done to study the cancer cells:

Other tests and procedures may be done depending on the signs and symptoms seen and where the cancer forms in the body.

Certain factors affect prognosis (chance of recovery) and treatment options.

The prognosis (chance of recovery) and treatment options depend on the following:

For non-Hodgkin lymphoma during pregnancy, the treatment options also depend on:

Some types of non-Hodgkin lymphoma spread more quickly than others do. Most non-Hodgkin lymphomas that occur during pregnancy are aggressive. Delaying treatment of aggressive lymphoma until after the baby is born may lessen the mother's chance of survival. Immediate treatment is often recommended, even during pregnancy.

Stages of Adult Non-Hodgkin Lymphoma

After adult non-Hodgkin lymphoma has been diagnosed, tests are done to find out if cancer cells have spread within the lymph system or to other parts of the body.

The process used to find out the type of cancer and if cancer cells have spread within the lymph system or to other parts of the body is called staging. The information gathered from the staging process determines the stage of the disease. It is important to know the stage of the disease in order to plan treatment. The results of the tests and procedures done to diagnose non-Hodgkin lymphoma are used to help make decisions about treatment.

The following tests and procedures may also be used in the staging process:

For pregnant women with non-Hodgkin lymphoma, staging tests and procedures that protect the baby from the harms of radiation are used. These tests and procedures include MRI, bone marrow aspiration and biopsy, lumbar puncture, and ultrasound. An ultrasound exam is a procedure in which high-energy sound waves (ultrasound) are bounced off internal tissues or organs and make echoes. The echoes form a picture of body tissues called a sonogram.

There are three ways that cancer spreads in the body.

Cancer can spread through tissue, the lymph system, and the blood:

Stages of adult non-Hodgkin lymphoma may include E and S.

Adult non-Hodgkin lymphoma may be described as follows:

The following stages are used for adult non-Hodgkin lymphoma:

Stage I

Stage I adult non-Hodgkin lymphoma; drawing shows cancer in one lymph node group above the diaphragm. An inset shows a lymph node with a lymph vessel, an artery, and a vein. Lymphoma cells containing cancer are shown in the lymph node.Stage I adult non-Hodgkin lymphoma. Cancer is found in one lymphatic area (lymph nodes, tonsils, thymus, or spleen). In stage IE (not shown), cancer is found in one organ or area outside the lymph nodes.

Stage I adult non-Hodgkin lymphoma is divided into stage I and stage IE.

Stage II

Stage II adult non-Hodgkin lymphoma is divided into stage II and stage IIE.

Stage III

Stage III adult non-Hodgkin lymphoma; drawing shows cancer in lymph node groups above and below the diaphragm, in the left lung, and in the spleen. An inset shows a lymph node with a lymph vessel, an artery, and a vein. Lymphoma cells containing cancer are shown in the lymph node.Stage III adult non-Hodgkin lymphoma. Cancer is found in one or more lymph node groups above and below the diaphragm (a). In stage IIIE, cancer is found in lymph node groups above and below the diaphragm and outside the lymph nodes in a nearby organ or area (b). In stage IIIS, cancer is found in lymph node groups above and below the diaphragm (a) and in the spleen (c). In stage IIIE plus S, cancer is found in lymph node groups above and below the diaphragm, outside the lymph nodes in a nearby organ or area (b), and in the spleen (c).

Stage III adult non-Hodgkin lymphoma is divided into stage III, stage IIIE, stage IIIS, and stage IIIE+S.

Stage IV

Stage IV adult non-Hodgkin lymphoma; drawing shows cancer in the liver, the left lung, and in one lymph node group below the diaphragm. The brain and pleura are also shown. One inset shows a close-up of cancer spreading through lymph nodes and lymph vessels to other parts of the body. Lymphoma cells containing cancer are shown inside one lymph node. Another inset shows cancer cells in the bone marrow.Stage IV adult non-Hodgkin lymphoma. Cancer is found throughout one or more organs that are not part of a lymphatic area (lymph nodes, tonsils, thymus, or spleen) (a); or in one organ that is not part of a lymphatic area and has spread to lymph nodes far away from that organ (b); or cerebrospinal fluid (not shown), the liver, bone marrow, or lungs.

In stage IV adult non-Hodgkin lymphoma, the cancer:

Adult non-Hodgkin lymphomas may be grouped for treatment according to whether the cancer is indolent or aggressive and whether affected lymph nodes are next to each other in the body.

See the General Information section for more information on the types of indolent (slow-growing) and aggressive (fast-growing) non-Hodgkin lymphoma.

Non-Hodgkin lymphoma can also be described as contiguous or noncontiguous:

Recurrent Adult Non-Hodgkin Lymphoma

Recurrent adult non-Hodgkin lymphoma is cancer that has recurred (come back) after it has been treated. The lymphoma may come back in the lymph system or in other parts of the body. Indolent lymphoma may come back as aggressive lymphoma. Aggressive lymphoma may come back as indolent lymphoma.

Treatment Option Overview

There are different types of treatment for patients with non-Hodgkin lymphoma.

Different types of treatment are available for patients with non-Hodgkin lymphoma. Some treatments are standard (the currently used treatment), and some are being tested in clinical trials. A treatment clinical trial is a research study meant to help improve current treatments or obtain information on new treatments for patients with cancer. When clinical trials show that a new treatment is better than the standard treatment, the new treatment may become the standard treatment. Patients may want to think about taking part in a clinical trial. Some clinical trials are open only to patients who have not started treatment.

For pregnant women with non-Hodgkin lymphoma, treatment is carefully chosen to protect the baby. Treatment decisions are based on the mother’s wishes, the stage of the non-Hodgkin lymphoma, and the age of the baby. The treatment plan may change as the signs and symptoms, cancer, and pregnancy change. Choosing the most appropriate cancer treatment is a decision that ideally involves the patient, family, and health care team.

Patients with non-Hodgkin lymphoma should have their treatment planned by a team of health care providers who are experts in treating lymphomas.

Treatment will be overseen by a medical oncologist, a doctor who specializes in treating cancer, or a hematologist, a doctor who specializes in treating blood cancers. The medical oncologist may refer you to other health care providers who have experience and are experts in treating adult non-Hodgkin lymphoma and who specialize in certain areas of medicine. These may include the following specialists:

Patients may develop late effects that appear months or years after their treatment for non-Hodgkin lymphoma.

Side effects from cancer treatment that begin during or after treatment and continue for months or years are called late effects. Treatment with chemotherapy, radiation therapy, or stem cell transplant for non-Hodgkin lymphoma may increase the risk of late effects.

Late effects of cancer treatment may include the following:

Some late effects may be treated or controlled. It is important to talk with your doctor about the effects cancer treatment can have on you. Regular follow-up to check for late effects is important.

Nine types of standard treatment are used:

Radiation therapy

Radiation therapy is a cancer treatment that uses high-energy x-rays or other types of radiation to kill cancer cells or keep them from growing. There are two types of radiation therapy:

Total-body irradiation is a type of external radiation therapy that is given to the entire body. It may be given before a stem cell transplant.

The way the radiation therapy is given depends on the type and stage of the cancer being treated. External radiation therapy is used to treat adult non-Hodgkin lymphoma, and may also be used as palliative therapy to relieve symptoms and improve quality of life.

For pregnant women with non-Hodgkin lymphoma, radiation therapy should be given after delivery, if possible, to avoid any risk to the baby. If treatment is needed right away, pregnant women may decide to continue the pregnancy and receive radiation therapy. However, lead used to shield the baby may not protect it from scattered radiation that could possibly cause cancer in the future.

Chemotherapy

Chemotherapy is a cancer treatment that uses drugs to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. When chemotherapy is taken by mouth or injected into a vein or muscle, the drugs enter the bloodstream and can reach cancer cells throughout the body (systemic chemotherapy). When chemotherapy is placed directly into the cerebrospinal fluid (intrathecal chemotherapy), an organ, or a body cavity such as the abdomen, the drugs mainly affect cancer cells in those areas (regional chemotherapy). Combination chemotherapy is treatment using two or more anticancer drugs. Steroid drugs may be added, to lessen inflammation and lower the body's immune response.

The way the chemotherapy is given depends on the type and stage of the cancer being treated.

Intrathecal chemotherapy may also be used in the treatment of lymphoma that first forms in the testicles or sinuses (hollow areas) around the nose, diffuse large B-cell lymphoma, Burkitt lymphoma, lymphoblastic lymphoma, and some aggressive T-cell lymphomas. It is given to lessen the chance that lymphoma cells will spread to the brain and spinal cord. This is called CNS prophylaxis.

Intrathecal chemotherapy; drawing shows the cerebrospinal fluid (CSF) in the brain and spinal cord, and an Ommaya reservoir (a dome-shaped container that is placed under the scalp during surgery; it holds the drugs as they flow through a small tube into the brain). Top section shows a syringe and needle injecting anticancer drugs into the Ommaya reservoir. Bottom section shows a syringe and needle injecting anticancer drugs directly into the cerebrospinal fluid in the lower part of the spinal column.Intrathecal chemotherapy. Anticancer drugs are injected into the intrathecal space, which is the space that holds the cerebrospinal fluid (CSF, shown in blue). There are two different ways to do this. One way, shown in the top part of the figure, is to inject the drugs into an Ommaya reservoir (a dome-shaped container that is placed under the scalp during surgery; it holds the drugs as they flow through a small tube into the brain). The other way, shown in the bottom part of the figure, is to inject the drugs directly into the CSF in the lower part of the spinal column, after a small area on the lower back is numbed.

In pregnant women, the baby is exposed to chemotherapy when the mother is treated, and some anticancer drugs cause birth defects. Because anticancer drugs are passed to the baby through the mother, both must be watched closely when chemotherapy is given.

See Drugs Approved for Non-Hodgkin Lymphoma for more information.

Immunotherapy

Immunotherapy is a treatment that uses the patient’s immune system to fight cancer. Substances made by the body or made in a laboratory are used to boost, direct, or restore the body’s natural defenses against cancer.

Immunomodulators are a type of immunotherapy. Lenalidomide is an immunomodulator used to treat adult non-Hodgkin lymphoma.

See Drugs Approved for Non-Hodgkin Lymphoma for more information.

Targeted therapy

Targeted therapy is a type of treatment that uses drugs or other substances to identify and attack specific cancer cells without harming normal cells. Monoclonal antibody therapy, proteasome inhibitor therapy, and kinase inhibitor therapy are types of targeted therapy used to treat adult non-Hodgkin lymphoma.

Monoclonal antibody therapy is a cancer treatment that uses antibodies made in the laboratory from a single type of immune system cell. These antibodies can identify substances on cancer cells or normal substances that may help cancer cells grow. The antibodies attach to the substances and kill the cancer cells, block their growth, or keep them from spreading. They may be used alone or to carry drugs, toxins, or radioactive material directly to cancer cells. Rituximab is a monoclonal antibody used to treat many types of non-Hodgkin lymphoma. Monoclonal antibodies that have been joined to radioactive material are called radiolabeled monoclonal antibodies. Yttrium Y 90-ibritumomab tiuxetan is an example of a radiolabeled monoclonal antibody. Monoclonal antibodies are given by infusion.

Proteasome inhibitor therapy blocks the action of proteasomes in cancer cells and may prevent the growth of tumors.

Kinase inhibitor therapy, such as idelalisib, blocks certain proteins, which may help keep lymphoma cells from growing and may kill them. It is used to treat indolent lymphoma. Ibrutinib, a type of Bruton's tyrosine kinase inhibitor therapy, is used to treat lymphoplasmacytic lymphoma and mantle cell lymphoma.

See Drugs Approved for Non-Hodgkin Lymphoma for more information.

Plasmapheresis

If the blood becomes thick with extra antibody proteins and affects circulation, plasmapheresis is done to remove extra plasma and antibody proteins from the blood. In this procedure, blood is removed from the patient and sent through a machine that separates the plasma (the liquid part of the blood) from the blood cells. The patient's plasma contains the unneeded antibodies and is not returned to the patient. The normal blood cells are returned to the bloodstream along with donated plasma or a plasma replacement. Plasmapheresis does not keep new antibodies from forming.

Watchful waiting

Watchful waiting is closely monitoring a patient’s condition without giving any treatment until signs or symptoms appear or change.

Antibiotic therapy

Antibiotic therapy is a treatment that uses drugs to treat infections and cancer caused by bacteria and other microorganisms.

See Drugs Approved for Non-Hodgkin Lymphoma for more information.

Surgery

Surgery may be used to remove the lymphoma in certain patients with indolent or aggressive non-Hodgkin lymphoma.

The type of surgery used depends on where the lymphoma formed in the body:

Patients who have a heart, lung, liver, kidney, or pancreas transplant usually need to take drugs to suppress their immune system for the rest of their lives. Long-term immunosuppression after an organ transplant can cause a certain type of non-Hodgkin lymphoma called post-transplant lymphoproliferative disorder (PLTD).

Small bowel surgery is often needed to diagnose celiac disease in adults who develop a type of T-cell lymphoma.

Stem cell transplant

Stem cell transplant is a method of giving high doses of chemotherapy and/or total-body irradiation and then replacing blood-forming cells destroyed by the cancer treatment. Stem cells (immature blood cells) are removed from the blood or bone marrow of the patient (autologous transplant) or a donor (allogeneic transplant) and are frozen and stored. After the chemotherapy and/or radiation therapy is completed, the stored stem cells are thawed and given back to the patient through an infusion. These reinfused stem cells grow into (and restore) the body’s blood cells.

Stem cell transplant; (Panel 1): Drawing of stem cells being removed from a patient or donor. Blood is collected from a vein in the arm and flows through a machine that removes the stem cells; the remaining blood is returned to a vein in the other arm. (Panel 2): Drawing of a health care provider giving a patient treatment to kill blood-forming cells. Chemotherapy is given to the patient through a catheter in the chest. (Panel 3): Drawing of stem cells being given to the patient through a catheter in the chest.Stem cell transplant. (Step 1): Blood is taken from a vein in the arm of the donor. The patient or another person may be the donor. The blood flows through a machine that removes the stem cells. Then the blood is returned to the donor through a vein in the other arm. (Step 2): The patient receives chemotherapy to kill blood-forming cells. The patient may receive radiation therapy (not shown). (Step 3): The patient receives stem cells through a catheter placed into a blood vessel in the chest.

New types of treatment are being tested in clinical trials.

This summary section describes treatments that are being studied in clinical trials. It may not mention every new treatment being studied. Information about clinical trials is available from the NCI website.

Vaccine therapy

Vaccine therapy is a type of biologic therapy. Biologic therapy is a treatment that uses the patient’s immune system to fight cancer. Substances made by the body or made in a laboratory are used to boost, direct, or restore the body’s natural defenses against cancer. This type of cancer treatment is also called biotherapy or immunotherapy. Vaccine therapy can also be a type of targeted therapy.

Patients may want to think about taking part in a clinical trial.

For some patients, taking part in a clinical trial may be the best treatment choice. Clinical trials are part of the cancer research process. Clinical trials are done to find out if new cancer treatments are safe and effective or better than the standard treatment.

Many of today's standard treatments for cancer are based on earlier clinical trials. Patients who take part in a clinical trial may receive the standard treatment or be among the first to receive a new treatment.

Patients who take part in clinical trials also help improve the way cancer will be treated in the future. Even when clinical trials do not lead to effective new treatments, they often answer important questions and help move research forward.

Patients can enter clinical trials before, during, or after starting their cancer treatment.

Some clinical trials only include patients who have not yet received treatment. Other trials test treatments for patients whose cancer has not gotten better. There are also clinical trials that test new ways to stop cancer from recurring (coming back) or reduce the side effects of cancer treatment.

Clinical trials are taking place in many parts of the country. See the Treatment Options section that follows for links to current treatment clinical trials. These have been retrieved from NCI's listing of clinical trials.

Follow-up tests may be needed.

Some of the tests that were done to diagnose the cancer or to find out the stage of the cancer may be repeated. Some tests will be repeated in order to see how well the treatment is working. Decisions about whether to continue, change, or stop treatment may be based on the results of these tests.

Some of the tests will continue to be done from time to time after treatment has ended. The results of these tests can show if your condition has changed or if the cancer has recurred (come back). These tests are sometimes called follow-up tests or check-ups.

Treatment Options for Indolent Non-Hodgkin Lymphoma

Treatment of indolent, stage I and contiguous stage II adult non-Hodgkin lymphoma may include the following:

If the tumor is too large to be treated with radiation therapy, the treatment options for indolent, noncontiguous stage II, III, or IV adult non-Hodgkin lymphoma will be used.

Treatment of indolent, noncontiguous stage II, III, or IV adult non-Hodgkin lymphoma may include the following:

After initial treatment with the monoclonal antibody rituximab with or without chemotherapy, more treatment with rituximab may be given.

Other treatments for indolent non-Hodgkin lymphoma depend on the type of non-Hodgkin lymphoma. Treatment may include the following:

About This PDQ Summary

About PDQ

Physician Data Query (PDQ) is the National Cancer Institute's (NCI's) comprehensive cancer information database. The PDQ database contains summaries of the latest published information on cancer prevention, detection, genetics, treatment, supportive care, and complementary and alternative medicine. Most summaries come in two versions. The health professional versions have detailed information written in technical language. The patient versions are written in easy-to-understand, nontechnical language. Both versions have cancer information that is accurate and up to date and most versions are also available in Spanish.

PDQ is a service of the NCI. The NCI is part of the National Institutes of Health (NIH). NIH is the federal government’s center of biomedical research. The PDQ summaries are based on an independent review of the medical literature. They are not policy statements of the NCI or the NIH.

Purpose of This Summary

This PDQ cancer information summary has current information about the treatment of adult non-Hodgkin lymphoma. It is meant to inform and help patients, families, and caregivers. It does not give formal guidelines or recommendations for making decisions about health care.

Reviewers and Updates

Editorial Boards write the PDQ cancer information summaries and keep them up to date. These Boards are made up of experts in cancer treatment and other specialties related to cancer. The summaries are reviewed regularly and changes are made when there is new information. The date on each summary ("Date Last Modified") is the date of the most recent change.

The information in this patient summary was taken from the health professional version, which is reviewed regularly and updated as needed, by the PDQ Adult Treatment Editorial Board.

Clinical Trial Information

A clinical trial is a study to answer a scientific question, such as whether one treatment is better than another. Trials are based on past studies and what has been learned in the laboratory. Each trial answers certain scientific questions in order to find new and better ways to help cancer patients. During treatment clinical trials, information is collected about the effects of a new treatment and how well it works. If a clinical trial shows that a new treatment is better than one currently being used, the new treatment may become "standard." Patients may want to think about taking part in a clinical trial. Some clinical trials are open only to patients who have not started treatment.

Clinical trials are listed in PDQ and can be found online at NCI's website. Many cancer doctors who take part in clinical trials are also listed in PDQ. For more information, call the Cancer Information Service 1-800-4-CANCER (1-800-422-6237).
