Neuroblastoma is a cancer that develops from immature nerve cells found in several areas of the body.

Neuroblastoma most commonly arises in and around the adrenal glands, which have similar origins to nerve cells and sit atop the kidneys. However, neuroblastoma can also develop in other areas of the abdomen and in the chest, neck and near the spine, where groups of nerve cells exist.

Neuroblastoma most commonly affects children age 5 or younger, though it may rarely occur in older children.

Symptoms

Signs and symptoms of neuroblastoma vary depending on what part of the body is affected.

Neuroblastoma in the abdomen — the most common form — may cause signs and symptoms such as:

• Abdominal pain
• A mass under the skin that isn't tender when touched
• Changes in bowel habits, such as diarrhea or constipation

Neuroblastoma in the chest may cause signs and symptoms such as:

• Wheezing
• Chest pain
• Changes to the eyes, including drooping eyelids and unequal pupil size

Other signs and symptoms that may indicate neuroblastoma include:

• Lumps of tissue under the skin
• Eyeballs that seem to protrude from the sockets (proptosis)
• Dark circles, similar to bruises, around the eyes
• Back pain
• Fever
• Unexplained weight loss
• Bone pain

Causes

In general, cancer begins with a genetic mutation that allows normal, healthy cells to continue growing without responding to the signals to stop, which normal cells do. Cancer cells grow and multiply out of control. The accumulating abnormal cells form a mass (tumor).

Neuroblastoma begins in neuroblasts — immature nerve cells that a fetus makes as part of its development process.

As the fetus matures, neuroblasts eventually turn into nerve cells and fibers and the cells that make up the adrenal glands. Most neuroblasts mature by birth, though a small number of immature neuroblasts can be found in newborns. In most cases, these neuroblasts mature or disappear. Others, however, form a tumor — a neuroblastoma.

Risk factors

Children with a family history of neuroblastoma may be more likely to develop the disease. Yet, familial neuroblastoma is thought to comprise a very small number of neuroblastoma cases. In most cases of neuroblastoma, a cause is never identified.

Diagnosis

Tests and procedures used to diagnose neuroblastoma include:

• Physical exam
• Urine and blood tests
• Imaging tests
• Removing a sample of tissue for testing
• Removing a sample of bone marrow for testing

Treatment

• Surgery
• Chemotherapy
• Radiation therapy
• Bone marrow transplant
• Immunotherapy
