Ganglioneuroblastoma is an intermediate tumor that arises from nerve tissues. An intermediate tumor is one that is between benign (slow-growing and unlikely to spread) and malignant (fast-growing, aggressive, and likely to spread).
Ganglioneuroblastoma mostly occurs in children ages 2 to 4 years. The tumor affects boys and girls equally. It occurs rarely in adults. Tumors of the nervous system have different degrees of differentiation. This is based on how the tumor cells look under the microscope. It can predict whether or not they are likely to spread.
Benign tumors are less likely to spread. Malignant tumors are aggressive, grow quickly, and often spread. A ganglioneuroma is less malignant in nature. A neuroblastoma (occurring in children over 1 year old) is usually malignant.
Ganglioneuroma is a tumor of the autonomic nervous system.
Neuroblastoma is a very rare type of cancerous tumor that develops from nerve tissue. It usually occurs in infants and children.
A ganglioneuroblastoma may be only in one area or it may be widespread, but it is usually less aggressive than a neuroblastoma. The cause is unknown.
Most commonly, a lump can be felt in the abdomen with tenderness.
This tumor may also occur at other sites, including:
- Chest cavity
Exams and Tests
The health care provider may do the following tests:
- Fine-needle aspiration of the tumor
- Bone marrow aspiration and biopsy
Bone marrow is the soft tissue inside bones that helps form blood cells. It is found in the hollow part of most bones. Bone marrow aspiration is th...Read Article Now Book Mark Article
- Bone scan
- CT scan or MRI scan of the affected area
- PET scan
- Metaiodobenzylguanidine (MIBG) scan
- Special blood and urine tests
- Surgical biopsy to confirm diagnosis
Depending on the type of tumor, treatment can involve surgery, and possibly chemotherapy and radiation therapy.
Because these tumors are rare, they should be treated in a specialized center by experts who have experience with them.
Organizations that provide support and additional information:
- Children's Oncology Group -- www.childrensoncologygroup.org
- The Neuroblastoma Children's Cancer Society -- www.neuroblastomacancer.org
The outlook depends on how far the tumor has spread, and whether some areas of the tumor contain more aggressive cancer cells.
Complications that may result include:
- Complications of surgery, radiation, or chemotherapy
Radiation therapy uses high-powered x-rays, particles, or radioactive seeds to kill cancer cells.Read Article Now Book Mark Article
- Spread of the tumor into surrounding areas
When to Contact a Medical Professional
Call your provider if you feel a lump or growth on your child's body. Make sure children receive routine examinations as part of their well-child care.
