Neuroblastoma

Neuroblastoma is a cancerous tumor originating from nerve cells, predominantly affecting children. This condition can manifest through a variety of symptoms, including fatigue, bone pain, sweating, shortness of breath, and bruising. Treatment typically involves chemotherapy, radiation therapy, and surgery. Commonly used drugs for treatment include alkylating agents and anthracyclines.

Causes

Neuroblastoma occurs when immature nerve cells, known as neuroblasts, grow abnormally due to DNA alterations. While it can develop in various body parts, it is most frequently found in the adrenal glands. The exact cause of these DNA changes remains unclear. Most cases aren't hereditary, but a small portion may have familial links. Certain genetic mutations or syndromes can elevate the risk of neuroblastoma. Since most cases occur spontaneously, there are no established preventive measures, as the condition is primarily influenced by uncontrollable factors.

Symptoms

Neuroblastoma affects young children and presents various symptoms depending on its location in the body. Key symptoms include:

• Abdomen Growth: A noticeable lump in the abdomen, potentially accompanied by a swollen belly, loss of appetite, and stomach pain.

• Chest Issues: Breathing difficulties, wheezing, or swelling in the neck and face if located in the chest.

• Spinal Complications: Back pain or weakness in the legs due to tumors near the spine.

• Bone and Eye Symptoms: Spreads can result in bone pain, often causing a limp, and bruising around the eyes, known as “raccoon eyes.”

• Hormonal Effects: It can produce hormones that may cause high blood pressure or uncontrollable eye movements.

Prompt medical attention is crucial if your child exhibits any of these symptoms.

Diagnosis

Diagnosing neuroblastoma involves a series of methods to identify the condition. Initially, a medical history review and physical examination focusing on the abdomen and neck are conducted. Blood and urine tests may detect elevated catecholamines, chemicals associated with neuroblastoma. Imaging tests like ultrasounds, CT scans, and MRIs allow closer examination of potential tumors. An MIBG scan using a radioactive tracer locates neuroblastoma cells throughout the body. Lastly, a biopsy is performed to confirm the diagnosis and assess tumor spread.

Treatments

The treatment plan for neuroblastoma is tailored based on the child's risk category and age, often involving a combination of therapies. For low-risk cases, surgery may suffice, especially if the tumor is small, and sometimes it might shrink on its own. Intermediate-risk cases commonly require surgery combined with chemotherapy to increase the chance of tumor removal. High-risk neuroblastoma demands a rigorous approach, using chemotherapy, surgery, radiation therapy, stem cell transplant, and immunotherapy. Immunotherapy uses medications to activate the immune system against cancer cells. Treatment plans are individualized, considering factors like tumor spread and genetic characteristics for the best approach.

Medications

Neuroblastoma treatment typically uses a combination of chemotherapy drugs, including:

• Cyclophosphamide

• Cisplatin

• Vincristine

• Doxorubicin

These medications are administered in cycles, allowing time for the body to recuperate. In high-risk cases, additional medications and combined therapies, like stem cell transplants, might be prescribed to boost treatment effectiveness. Chemotherapy side effects such as hair loss, nausea, and fatigue generally subside post-treatment. It is vital for parents to consult with healthcare providers about side effect management to ensure optimal care.

Prevention

Preventing neuroblastoma remains challenging due to the unclear causes of the condition. Most neuroblastomas arise from spontaneous DNA mutations in nerve cells, unrelated to environmental or lifestyle factors. Familial cases, though rare, do occur involving hereditary components. For families with a history, genetic counseling is advised to evaluate risks. Effective prevention strategies are currently lacking, but being alert to early symptoms can aid in prompt diagnosis and treatment, potentially improving outcomes. Research continues into genetic and prenatal factors, though practical prevention measures are still absent.
