What is childhood Hodgkin lymphoma?
Hodgkin disease is a kind of lymphoma, an uncommon cancer that
starts in the lymph system. The lymph system includes the lymph
nodes, lymph vessels, and other parts of the body's immune and
blood-forming systems, such as the spleen and bone marrow. The
lymph system makes, stores, and carries infection-fighting white
blood cells called lymphocytes. Lymph nodes and lymph vessels are
located throughout the body.
Hodgkin lymphoma, also called Hodgkin disease, is one of the most
curable cancers.
How does it occur?
There are no known risk factors for childhood Hodgkin lymphoma. It
is very rare in children under the age of 5. It seems to affect
boys more often than girls.
For reasons that are not known, when people have Hodgkin lymphoma
their bodies make too many abnormal lymphocytes. These cancer
cells crowd into the lymph nodes and may also invade other parts
of the body. Tumors may then grow and interfere with normal body
functions.
What are the symptoms?
Symptoms include:
- painless swelling of lymph nodes, in the neck, armpits, or
groin
- fever
- night sweats
- unexplained weight loss
- itching
- tiredness.
How is it diagnosed?
Your child's healthcare provider will ask about symptoms and
examine your child. A sample of tissue will be taken from a
swollen lymph node and examined under a microscope. This removal
of a sample of tissue is called a biopsy. If your child has
Hodgkin lymphoma, unusual cells called Reed-Sternberg cells will
be found in the tissue.
If Hodgkin lymphoma is found, more tests will be done to learn the
stage or the extent of the disease. These tests may include:
- blood tests
- chest X-rays
- CT scans of the chest and abdomen
- biopsy of the bone marrow to see if the disease has spread
there.
How is it treated?
The diagnosis of Hodgkin lymphoma is classified into stages,
depending on the areas of lymph nodes and other organs affected.
There are several types of Hodgkin disease. Treatment will depend
on the type and stage of disease, as well as your child's general
health.
Radiation therapy or anticancer drugs (chemotherapy) are used to
shrink tumors and kill cancer cells. Side effects of chemotherapy
include nausea and hair loss. Nausea can be controlled with drugs.
Hair loss cannot be controlled. Children are also at risk for
serious infections during and after treatment.
If Hodgkin is not cured with chemotherapy, stem cells (immature
blood cells) may be transplanted from your child's blood or bone
marrow or from a donor's blood or marrow. Other types of blood
cell treatments are also available to help the child maintain a
healthy bone marrow.
Marrow is taken from the bones before treatment. The marrow is
then frozen, and the child is given high-dose chemotherapy with or
without radiation therapy to treat the cancer. The marrow taken
out is then thawed and given back through a needle in a vein to
replace the marrow that was destroyed by the chemotherapy.
