What Is Childhood Diffuse Large B-cell Lymphoma?
Diffuse large B-cell lymphoma is a cancer of mature B-lymphocytes. It is a form of non-Hodgkin lymphoma, which is a type of cancer that originates in cells of the immune system, called lymphocytes.
- Diffuse large B-cell lymphoma usually starts in lymph nodes, but may also start in the bone, skin, or other organs of the body.
- It can spread to many parts of the body. When it is only in one area of the body (stage 1 or 2) it is called localized. When it is more extensive (stage 3 or 4) it is called advanced.
- With current therapies, more than 90% of children with diffuse large B-cell lymphoma are cured of the disease.
Diffuse large B-cell lymphoma is more common in adults than in children and behaves differently in adults than in children. In children and adolescents, diffuse large B-cell lymphoma is usually treated in the same way that Burkitt lymphoma is treated. Although diffuse large B-cell lymphoma is an aggressive cancer, it is not as fast growing as Burkitt lymphoma.
How We Treat Childhood Diffuse Large B-cell Lymphoma
Children and teens with diffuse large B-cell lymphoma, a type of non-Hodgkin lymphoma, are treated at Dana-Farber/Boston Children's Cancer and Blood Disorders Center through the Childhood Lymphoma Program in our Childhood Hematologic Malignancy Center. Dana-Farber/Boston Children's offers internationally renowned care for children with cancers of the blood and immune system.
Dana-Farber/Boston Children's also offers a wide array of support services and programs for pediatric patients and their families during and after cancer treatment.
The cure rate for diffuse large B-cell lymphoma is very high. For the purpose of deciding how much treatment is necessary, diffuse large B-cell lymphoma may be divided by stage (localized or advanced) or by the risk group classification that is used for Burkitt lymphoma.
Newly diagnosed, localized, diffuse large B-cell lymphoma, may be treated with a short, 9-week course of chemotherapy. This includes the drugs cyclophosphamide, doxorubicin, vincristine, and prednisone.
If your child has advanced diffuse large B-cell lymphoma, treatment is the same as the treatment for Burkitt lymphoma.
Older adolescents may be treated with the same chemotherapy regimen that is used for adult diffuse large B-cell lymphoma. This treatment program is called "R-CHOP."
For diffuse large B-cell lymphoma that does not respond to initial treatment (refractory) or that comes back after treatment (relapse), treatment recommendations are the same as for relapsed or refractory Burkitt lymphoma.

Long-term Follow-up for Children with Diffuse Large B-cell Lymphoma
Childhood cancer was once considered to be invariably fatal, but today, the majority of children diagnosed with cancer can expect to be long-term survivors. With current therapies, more than 90% of children with diffuse large B-cell lymphoma are cured of the disease.
Along with survivorship come numerous complex issues: the long-term effects of treatment and the risk of second cancers, as well as social and psychological concerns. For these reasons, survivors of childhood diffuse large B-cell lymphoma should receive regular follow-up monitoring and care.
Since 1993, physicians, nurses, researchers, and psychologists in our pediatric cancer survivorship programs at the David B. Perini Jr. Quality of Life Clinic at Dana-Farber have helped thousands of childhood cancer survivors, treated at the Dana-Farber/Boston Children's and at other hospitals in New England and elsewhere, to manage these long-term challenges of surviving cancer.
