General Information About Childhood Hodgkin Lymphoma

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

Childhood Hodgkin lymphoma is a type of cancer that develops in the lymph system. The lymph system is part of the immune system. It helps protect the body from infection and disease.

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.

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.

Bits of lymph tissue are also found in other parts of the body such as the lining of the gastrointestinal tract, bronchus, and skin.

There are two general types of lymphoma: Hodgkin lymphoma and non-Hodgkin lymphoma. This summary is about the treatment of childhood Hodgkin lymphoma.

Hodgkin lymphoma occurs most often in adolescents 15 to 19 years of age. The treatment for children and adolescents is different than treatment for adults.

For information about childhood non-Hodgkin lymphoma or adult Hodgkin lymphoma see the following PDQ summaries:

The two main types of childhood Hodgkin lymphoma are classic and nodular lymphocyte-predominant.

The two main types of childhood Hodgkin lymphoma are:

Epstein-Barr virus infection and a family history of Hodgkin lymphoma can increase the risk of childhood 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 child’s doctor if you think your child may be at risk.

Risk factors for childhood Hodgkin lymphoma include the following:

Being exposed to common infections in early childhood may decrease the risk of Hodgkin lymphoma in children because of the effect it has on the immune system.

Signs of childhood Hodgkin lymphoma include swollen lymph nodes, fever, drenching night sweats, and weight loss.

The signs and symptoms of Hodgkin lymphoma depend on where the cancer forms in the body and the size of the cancer. These and other signs and symptoms may be caused by childhood Hodgkin lymphoma or by other conditions. Check with your child's doctor if your child has any of the following:

Fever for no known reason, weight loss for no known reason, or drenching night sweats are called B symptoms. B symptoms are an important part of staging Hodgkin lymphoma and understanding the patient's chance of recovery.

Tests that examine the lymph system and other parts of the body are used to diagnose and stage childhood Hodgkin lymphoma.

Tests and procedures that make pictures of the lymph system and other parts of the body help diagnose childhood Hodgkin lymphoma and show how far the cancer has spread. The process used to find if cancer cells have spread outside the lymph system is called staging. To plan treatment, it is important to know if cancer has spread to other parts of the body.

These tests and procedures may include the following:

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

The prognosis and treatment options depend on the following:

The treatment options also depend on:

Most children and adolescents with newly diagnosed Hodgkin lymphoma can be cured.

Stages of Childhood Hodgkin Lymphoma

After childhood 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 if cancer has 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. The results of the tests and procedures done to diagnose and stage Hodgkin lymphoma are used to help make decisions about treatment.

There are three ways that cancer spreads in the body.

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

The following stages are used for childhood Hodgkin lymphoma:

Stage I

Stage I childhood Hodgkin lymphoma; drawing shows cancer in one lymph node group above the diaphragm and in the spleen. Also shown are the Waldeyer’s ring and the thymus. An inset shows a lymph node with a lymph vessel, an artery, and a vein. Cancer cells are shown inside the lymph node.

Stage I childhood Hodgkin lymphoma. Cancer is found in one or more lymph nodes in a group of lymph nodes or, in rare cases, cancer is found in the Waldeyer’s ring, thymus, or spleen. In stage IE (not shown), cancer has spread to one area outside the lymph system.

Stage I is divided into stage I and stage IE.

Stage II

Stage II is divided into stage II and stage IIE.

Stage III

Stage III childhood Hodgkin lymphoma; drawing shows cancer in lymph node groups above and below the diaphragm (a). Also shown is cancer that has spread outside the lymph nodes to a nearby area in the left lung (b) and cancer in the spleen (c). An inset shows a lymph node with a lymph vessel, an artery, and a vein. Cancer cells are shown inside the lymph node.

Stage III childhood Hodgkin lymphoma. Cancer is found in lymph node groups above and below the diaphragm (a). In stage IIIE, cancer is found in lymph node groups above and below the diaphragm (a) 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 IIIS plus E, cancer is found in lymph node groups above and below the diaphragm (a), outside the lymph nodes in a nearby organ or area (b), and in the spleen (c).

Stage III is divided into stage III, stage IIIE, stage IIIS, and stage IIIE,S.

Stage IV

Stage IV childhood Hodgkin lymphoma; drawing shows cancer in the liver (a) the left lung (b), and in one lymph node group below the diaphragm (b). The brain and pleura are also shown. An inset on the left shows cancer cells inside a lymph node and cancer spreading through lymph nodes and lymph vessels to other parts of the body. An inset on the right shows cancer cells in the bone marrow.

Stage IV childhood Hodgkin lymphoma. Cancer is found outside the lymph nodes throughout one or more organs (a); or outside the lymph nodes in one organ and has spread to lymph nodes far away from that organ (b); or in the lung, liver, bone marrow, or cerebrospinal fluid (not shown).

In stage IV, the cancer:

In addition to the stage number, the letters A, B, E, or S may be noted.

The letters A, B, E, or S may be used to further describe the stage of childhood Hodgkin lymphoma.

Childhood Hodgkin lymphoma is treated according to risk groups.

Untreated childhood Hodgkin lymphoma is divided into risk groups based on the stage, size of the tumor, and whether the patient has B symptoms (fever, weight loss, or drenching night sweats). The risk group describes the likelihood that Hodgkin lymphoma will not respond to treatment or recur (come back) after treatment. It is used to plan initial treatment.

Low-risk Hodgkin lymphoma requires fewer cycles of treatment, fewer anticancer drugs, and lower doses of anticancer drugs than high-risk lymphoma.

Sometimes childhood Hodgkin lymphoma does not respond to treatment or comes back after treatment.

Primary refractory Hodgkin lymphoma is lymphoma that continues to grow or spread during treatment.

Recurrent 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, such as the lungs, liver, bones, or bone marrow.

Treatment Option Overview

There are different types of treatment for children with Hodgkin lymphoma.

Different types of treatment are available for children with Hodgkin lymphoma. Some treatments are standard 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.

Because cancer in children is rare, taking part in a clinical trial should be considered. Some clinical trials are open only to patients who have not started treatment.

Children with Hodgkin lymphoma should have their treatment planned by a team of health care providers who are experts in treating childhood cancer.

Treatment will be overseen by a pediatric oncologist, a doctor who specializes in treating children with cancer. The pediatric oncologist works with other pediatric health care providers who are experts in treating children with Hodgkin lymphoma and who specialize in certain areas of medicine. These may include the following specialists:

The treatment of Hodgkin lymphoma in adolescents and young adults may be different than the treatment for children. Some adolescents and young adults are treated with an adult treatment regimen.

Six types of standard treatment are used:

Chemotherapy

Chemotherapy is a cancer treatment that uses one or more drugs to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Cancer treatment using more than one chemotherapy drug is called combination chemotherapy. 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).

The way the chemotherapy is given depends on the risk group. For example, children with low-risk Hodgkin lymphoma receive fewer cycles of treatment, fewer anticancer drugs, and lower doses of anticancer drugs than children with high-risk lymphoma.

See Drugs Approved for Hodgkin Lymphoma for more information.

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. External radiation therapy uses a machine outside the body to send radiation toward the area of the body with cancer.

Certain ways of giving radiation therapy can help keep radiation from damaging nearby healthy tissue. These types of external radiation therapy include the following:

Radiation therapy may be given, based on the child’s risk group and chemotherapy regimen. The radiation is given only to the lymph nodes or other areas with cancer.

Targeted therapy

Targeted therapy is a treatment that uses drugs or other substances to identify and attack cancer cells. Targeted therapies usually cause less harm to normal cells than chemotherapy and radiation therapy do. Types of targeted therapy include the following:

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. This type of cancer treatment is also called biologic therapy or biotherapy. Types of immunotherapy include the following:

Immune checkpoint inhibitor; the panel on the left shows the binding of proteins PD-L1 (on the tumor cell) to PD-1 (on the T cell), which keeps T cells from killing tumor cells in the body. Also shown are a tumor cell antigen and T cell receptor. The panel on the right shows immune checkpoint inhibitors (anti-PD-L1 and anti-PD-1) blocking the binding of PD-L1 to PD-1, which allows the T cells to kill tumor cells.

Immune checkpoint inhibitor. Checkpoint proteins, such as PD-L1 on tumor cells and PD-1 on T cells, help keep immune responses in check. The binding of PD-L1 to PD-1 keeps T cells from killing tumor cells in the body (left panel). Blocking the binding of PD-L1 to PD-1 with an immune checkpoint inhibitor (anti-PD-L1 or anti-PD-1) allows the T cells to kill tumor cells (right panel).

Surgery

Surgery may be done to remove as much of the tumor as possible for localized nodular lymphocyte-predominant Hodgkin lymphoma in children.

High-dose chemotherapy with stem cell transplant

High doses of chemotherapy are given to kill cancer cells. Healthy cells, including blood-forming cells, are also destroyed by the cancer treatment. Stem cell transplant is a treatment to replace the blood-forming cells. Stem cells (immature blood cells) are removed from the blood or bone marrow of the patient or a donor and are frozen and stored. After the patient completes chemotherapy, 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.

See Drugs Approved for Hodgkin Lymphoma for more information.

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.

Proton beam radiation therapy

Proton-beam therapy is a type of high-energy, external radiation therapy that uses streams of protons (small, positively-charged particles of matter) to make radiation. This type of radiation therapy may help lessen the damage to healthy tissue near the tumor, such as the breast, heart, and lungs.

Treatment for childhood Hodgkin lymphoma causes side effects and late effects.

For information about side effects that begin during treatment for cancer, see our Side Effects page.

Side effects from cancer treatment that begin after treatment and continue for months or years are called late effects. Because late effects affect health and development, regular follow-up exams are important.

Late effects of cancer treatment may include the following:

For female survivors of Hodgkin lymphoma, there is an increased risk of breast cancer. This risk depends on the amount of radiation the breast received during treatment and the chemotherapy regimen used. The risk of breast cancer is decreased if radiation to the ovaries was also given.

It is suggested that female survivors who received radiation therapy to the breast have a mammogram and MRI once a year starting 8 years after treatment or at age 25 years, whichever is later. It is also suggested that female survivors do a breast self-exam every month beginning at puberty and have a breast exam done by a health professional every year beginning at puberty until age 25 years.

Some late effects may be treated or controlled. It is important to talk with your child's doctors about the possible late effects caused by some treatments. (See the PDQ summary on Late Effects of Treatment for Childhood Cancer for more information).

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. Information about clinical trials supported by NCI can be found on NCI’s clinical trials search webpage. Clinical trials supported by other organizations can be found on the ClinicalTrials.gov website.

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 child's condition has changed or if the cancer has recurred (come back). These tests are sometimes called follow-up tests or check-ups.

For patients who receive chemotherapy alone, a PET scan may be done 3 weeks or more after treatment ends. For patients who receive radiation therapy last, a PET scan should not be done until 8 to 12 weeks after treatment ends.

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 can be found online at NCI's website. For more information, call the Cancer Information Service (CIS), NCI's contact center, at 1-800-4-CANCER (1-800-422-6237).
