Question 1

What is neuroblastoma?

Accepted Answer

Neuroblastoma is a cancer of immature nerve cells (neuroblasts) that most commonly arises in the adrenal glands, but may also develop in the neck, chest, abdomen, or spine. It almost exclusively affects infants and very young children—typically under age 5.

Question 2

What causes neuroblastoma in children?

Accepted Answer

The exact cause of neuroblastoma is not fully understood, but it may involve genetic mutations during fetal development that affect nerve cell growth. Some rare hereditary forms are linked to specific gene changes.

Question 3

What are the symptoms of neuroblastoma?

Accepted Answer

Symptoms vary based on tumor location but may include a lump in the abdomen or chest, bone pain, fatigue, dark circles under the eyes, or unexplained fever. In some cases, neuroblastoma can affect hormone levels or cause high blood pressure.

Question 4

How is neuroblastoma diagnosed?

Accepted Answer

Neuroblastoma is typically diagnosed through imaging tests such as MRI, CT scans, or MIBG scans, followed by a biopsy. Blood and urine tests may also help detect tumor markers like catecholamines.

Question 5

What is Stage 4 neuroblastoma?

Accepted Answer

Stage 4 neuroblastoma refers to cancer that has spread to distant parts of the body, such as bones, liver, or lymph nodes. It is considered high-risk and requires aggressive treatment.

Question 6

Can neuroblastoma be cured?

Accepted Answer

Yes—for low- or intermediate-risk cases, cure rates exceed 90%. Some early-stage tumors even regress spontaneously. However, high-risk neuroblastoma requires intensive treatment and outcomes vary significantly.

Question 7

What treatments are used for neuroblastoma?

Accepted Answer

Treatment depends on risk level and may include surgery, chemotherapy, stem cell transplant, radiation, immunotherapy (anti?GD2 antibodies), isotretinoin, and targeted therapies. High-risk cases often receive combined, aggressive regimens.

Question 8

Can neuroblastoma return after treatment?

Accepted Answer

Yes, neuroblastoma can recur, especially in high-risk patients. Ongoing monitoring is essential, and relapse treatment may involve additional chemotherapy, new drug trials, or immunotherapy options.

Question 9

At what age is neuroblastoma most common?

Accepted Answer

Neuroblastoma is most commonly diagnosed in children under the age of 5, with the highest occurrence in infants and toddlers.

Question 10

Can neuroblastoma affect adults?

Accepted Answer

While extremely rare, neuroblastoma can occur in adults. Adult cases tend to behave differently and may require alternative treatment approaches.
