On this ped-onc site: Warning Signs of Childhood Cancer: Lymphomas

Lymphomas are malignant cell infiltrations of the lymphatic system. The lymph system includes the nodes with which of us are familiar, located in the neck, armpit, and groin. These nodes are only part of the lymph system, as they are connected to each other and to the spleen, thymus, and parts of the tonsils, stomach, and small intestine by a network of vessels. The vessels carry a colorless, watery fluid called lymph, and contains lymphocytes. Once a malignancy begins in one part of the lymph system, it often spreads throughout the rest of the system before it is detected. The different lymphomas share similar symptoms such as painless swelling of the lymph nodes, fever and fatigue.

Lymphomas, close cousins to the leukemias, are divided into many sub-groups according to cell types. Broadly, they are classified as either non-Hodgkin's and Hodgkin's. Of these two types, non-Hodgkin's (NHL) is the more common in children. About 15 types of NHL have been identified, although three of these types are the main ones which occur in children (see below). NHL in children occurs more frequently between the ages of ten and twenty than under ten. Hodgkins cases in children are rare under five years of age; in children under age 10, it is more common in boys than girls. Currently, Hodgkin's lymphoma is more curable than non-Hodgkin's.

NHL (Non-Hodgkin's Lymphoma)

The three types of NHL that occur most often in children are:

Descriptions of NHL are given at other web sites, especially:

The author of "Mike's" pages has done excellent jobs in describing lymphomas, including details on cell classification, diagnosis, the lymph system, and statistics. Both pages focus largely on adult rather than childhood concerns, but the descriptions do cover the full age range of the disease.

Statistics for NHL

Hodgkin's Lymphoma

Recommended cancer.gov link: NCI PDQ

Hodgkin's lymphoma is characterized by the presence of large, binucleated cells called "Reed-Sternberg cells." The normal counterpart of these cells is not known - they are of either a B or a T lineage. Hodgkin's disease usually presents with enlarged lymph nodes. Hodgkin's has a cure rate of 75%.

Descriptions of Hodgkin's are given at NCI/cancer.gov:

Treatment for Lymphomas

The treatment for all types of lymphoma depends on type, stage, and grade of disease. The types are listed in the descriptions and the embedded links. The stages and grades are outlined below.

Stages:

Grades:

Lymphomas are usually treated by a combination of chemotherapy, radiation, surgery, and/or bone marrow transplants. The cure rate varies greatly depending on the type of lymphoma and the progression of the disease.
