Stages of Childhood Non-Hodgkin Lymphoma
There are three ways that cancer spreads in the body.
Cancer can spread through tissue, the lymph system, and the blood:
- Tissue. The cancer spreads from where it began by growing into nearby areas.
- Lymph system. The cancer spreads from where it began by getting into the lymph system. The cancer travels through the lymph vessels to other parts of the body.
- Blood. The cancer spreads from where it began by getting into the blood. The cancer travels through the blood vessels to other parts of the body.
The following stages are used for childhood non-Hodgkin lymphoma:
Stage I
In stage I childhood non-Hodgkin lymphoma, cancer is found:
- in one group of lymph nodes; or
- in one area outside the lymph nodes.
No cancer is found in the abdomen or mediastinum (area between the lungs).
Stage II
In stage II childhood non-Hodgkin lymphoma, cancer is found:
- in one area outside the lymph nodes and in nearby lymph nodes; or
- in two or more areas above or below the diaphragm, and may or may not have spread to nearby lymph nodes; or
- to have started in the stomach or intestines and can be completely removed by surgery. Cancer may or may not have spread to certain nearby lymph nodes.
Stage III
In stage III childhood non-Hodgkin lymphoma, cancer is found:
Stage IV
In stage IV childhood non-Hodgkin lymphoma, cancer is found in the bone marrow, brain, or cerebrospinal fluid. Cancer may also be found in other parts of the body.
Childhood non-Hodgkin lymphoma is also described as low-stage or high-stage.
Treatment for childhood non-Hodgkin lymphoma is based on whether the cancer is low-stage or high-stage. Low-stage lymphoma has not spread beyond the area in which it began. High-stage lymphoma has spread beyond the area in which it began. Stage I and stage II are usually considered low-stage. Stage III and stage IV are usually considered high-stage.
Recurrent Childhood Non-Hodgkin Lymphoma
Recurrent childhood non-Hodgkin lymphoma is cancer that has recurred (come back) after it has been treated. Childhood non-Hodgkin lymphoma may come back in the lymph system or in other parts of the body.
