Neuroblastoma survival rates depend on the child’s age and the spread of cancer. Early detection and treatment can result in a cure rate of over 90%, but advanced stages have lower survival rates. Stage 1 has a survival rate of over 90%, while stage 4 has a survival rate of 10-40% for patients over one year old.
Two factors that influence the survival rate of neuroblastoma are the age of the child and the spread of the cancer. In some cases affecting very young children, the tumor may go away without treatment or it may grow larger and form a noncancerous growth that can be removed by surgery. Younger children generally have a better prognosis than older ones. For children of any age, if the cancer is caught very early before it spreads, the cure rate is over 90%. The long-term prognosis of this type of childhood cancer will worsen as the cancer has advanced.
A cancerous tumor is classified as stage 1 to stage 4. In stage 1, there is only one tumor and it is limited to the location where the cancerous cells originated. It can be completely surgically removed and all lymph nodes are free of cancer. The survival rate of neuroblastoma at this stage is over 90%.
Stage 2A classifies a tumor that is not easily removed but is only present on one side of the body. All lymph nodes are free of cancer. A stage 2B cancer is still only on one side of the body, but lymph nodes on the same side of the body are affected. The lymph nodes on the opposite side are free of cancer. Stage 2 neuroblastoma survival rates of patients older than one year will range from 75 to 90 percent.
A malignant tumor can be classified as Stage 3 for several reasons. It is placed in this category if it has spread and is found on both sides of the body, with or without lymph nodes on both sides affected. When doctors refer to cancer as being on both sides, they mean it is on either side of an imaginary line drawn down the center of the body. A tumor is also referred to as Stage 3 if it is on one side of the body, but is found in the lymph nodes on the other side. The neuroblastoma survival rate of stage 3 and stage 2B patients is about 50 to 70 percent if they are older than a year, and about 80 percent if they are younger.
Stage 4 cancers refer to those that have advanced to affect the lymph nodes, bone marrow, and other organs. Stage 4S applies to newborns who have cancer on only one side of the body but which has spread to other organs. The survival rate of stage 4 and stage 4S neuroblastoma of patients younger than one year is 50 to 80%, while the rate for patients older than one year is 10 to 40%.
