Neuroblastoma

What is Neuroblastoma?

Neuroblastoma is a type of cancer that develops from immature nerve cells called neuroblasts. These cells are found in various parts of the body, but neuroblastoma commonly originates in the adrenal glands (located on top of the kidneys), as well as in nerve tissues along the spine, chest, abdomen, or pelvis.

It primarily affects young children, usually under the age of five, though it can occasionally occur in older children and adults.

Side Effects of Neuroblastoma

The symptoms and side effects of neuroblastoma vary depending on the location and size of the tumor. Common signs may include abdominal swelling or pain, a lump in the abdomen or neck, bone pain, unexplained weight loss, fatigue, and changes in bowel habits.

In some cases, the cancer may spread to other parts of the body, such as the bones, bone marrow, liver, or skin, leading to additional symptoms related to those areas.

How is Neuroblastoma Diagnosed?

Diagnosing neuroblastoma often involves a combination of imaging tests, such as ultrasound, CT scan, MRI, and MIBG scan (a type of nuclear medicine scan that uses a radioactive tracer to detect neuroblastoma cells).

Biopsy, where a small sample of tissue is taken for examination under a microscope, is also commonly performed to confirm the diagnosis and determine the specific characteristics of the tumor.

Potential Treatment of Neuroblastoma

The treatment of neuroblastoma depends on several factors, including the child's age, the stage and location of the tumor, and the tumor biology. Treatment strategies may include:

• Surgery: Surgical removal of the tumor is often the first step if the tumor is localized and can be safely removed without causing significant damage to surrounding organs.
• Chemotherapy: Powerful drugs are used to kill cancer cells throughout the body, particularly if the tumor has spread beyond its original location.
  
• Radiation Therapy: High-energy beams, such as X-rays or protons, are targeted at the tumor to destroy cancer cells and shrink the tumor size.
  
• Immunotherapy: This treatment boosts the body's immune system to help fight cancer cells, especially in cases where the cancer has a high risk of recurrence.
  
• Stem Cell Transplantation: In some cases, high-dose chemotherapy may be used to kill cancer cells followed by a stem cell transplant to help the body recover.
  
• Targeted Therapy: Drugs specifically designed to target certain molecules involved in the growth and spread of neuroblastoma cells may be used, particularly in cases where standard treatments are less effective.
