Stages of Childhood Hodgkin Lymphoma
In stage IV, the cancer:
- is found outside the lymph nodes throughout one or more organs, and may be in lymph nodes near those organs; or
- is found outside the lymph nodes in one organ and has spread to lymph nodes far away from that organ; or
- is found in the lung, liver, or bone marrow.
Untreated, classical Hodgkin lymphoma is divided into risk groups.
Untreated, classical childhood Hodgkin lymphoma is divided into risk groups based on the bulk of the tumor (tumors that are 5 centimeters or larger are considered "bulky") and whether the patient has "b" symptoms (fever, weight loss, or night sweats). Treatment is based on the risk group.
- Low-risk disease:
- Patients with stage I or stage II disease; and
- No bulky tumors or "b" symptoms.
- Intermediate-risk disease:
- Patients with stage I or stage II disease, with bulky tumors, or with "b" symptoms; or
- Patients with stage III or stage IV disease without "b" symptoms.
- High-risk disease: Patients with stage III or stage IV disease with "b" symptoms.
After initial chemotherapy, a PET scan may be done.
A PET scan may be done after one or two cycles of chemotherapy and again after chemotherapy ends, to find out how well the chemotherapy worked.
