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).
Five types of standard treatment are used:
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, 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 more than one anticancer drug.
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 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. External radiation therapy uses a machine outside the body to send radiation toward the cancer. Internal radiation therapy uses a radioactive substance sealed in needles, seeds, wires, or catheters that are placed directly into or near the cancer.
Radiation therapy may be given, based on the child's risk group and chemotherapy regimen. External radiation therapy is used for childhood Hodgkin lymphoma. The radiation is given only to the lymph nodes or other areas with cancer.
Targeted therapy is a type of treatment that uses drugs or other substances to identify and attack specific cancer cells without harming normal cells. One type of targeted therapy being used in the treatment of childhood Hodgkin lymphoma is monoclonal antibody therapy.
