Neuroblastoma Treatment (PDQ®): Treatment - Patient Information [NCI] - Stages of Neuroblastoma
Stage 4 is divided into stage 4 and stage 4S.
- In stage 4, the tumor has spread to distant lymph nodes, the skin, or other parts of the body.
- In stage 4S, the following are true:
- the child is younger than 18 months; and
- the cancer has spread to the skin, liver, and/or bone marrow; and
- the tumor is in only one area and all of the tumor that can be seen may be completely removed during surgery; and/or
- cancer cells may be found in the lymph nodes near the tumor.
Treatment of neuroblastoma is based on risk groups.
For many types of cancer, stages are used to plan treatment. For neuroblastoma, treatment depends on risk groups. The stage of neuroblastoma is one factor used to determine risk group. Other factors are the age of the child, tumor histology, and tumor biology.
There are 3 risk groups: low risk, intermediate risk, and high risk.
- Low-risk and intermediate-risk neuroblastoma have a good chance of being cured.
- High-risk neuroblastoma may be difficult to cure.
