What is Neuroendocrine Tumour?

Neuroendocrine tumors (NETs) are neoplasms that arise from cells of the endocrine (hormonal) and nervous systems. Many are benign, while some are malignant.

They most commonly occur in the intestine, where they are often called carcinoid tumors, but may grow slowly or aggressively and spread to other parts of the body, like the pancreas and the lungs.

The World Health Organization (WHO) classification scheme places neuroendocrine tumors into three main categories, which emphasize the tumor grade rather than the anatomical origin:

• well-differentiated neuroendocrine tumours, further subdivided into tumors with benign and those with uncertain behavior
• well-differentiated (low grade) neuroendocrine carcinomas with low-grade malignant behavior
• poorly differentiated (high grade) neuroendocrine carcinomas, which are the large cell neuroendocrine and small cell carcinomas.

How many people are at risk?

Neuroendocrine Tumour is a rare form of cancer and overall, it is estimated that more than 12,000 people in the United States are diagnosed with a neuroendocrine tumor each year, while fewer than 1 million cases are seen each year in India.

What are the risk factors?

The following factors can raise a person's risk of developing a neuroendocrine tumor:

• Age
• Gender
• Race/ethnicity
• Family history
• Immune system suppression
• Merkel cell polyomavirus (MCV)
• Arsenic exposure
• Sun exposure

What are the symptoms/signs of Neuroendocrine Tumour?

Many people do not develop symptoms and the tumour is detected incidentally. When symptoms occur, they can vary based on the location of the tumour.

In rare cases, skin flushing or fluctuating blood sugar levels may occur.

Sometimes the cause of a symptom may be another medical condition that is not cancer.

Neuroendocrine Tumor: Diagnosis

In order to choose a diagnostic test, doctors may consider the following factors:

• The type of tumor suspected
• Your signs and symptoms
• Your age and medical condition
• The results of earlier medical tests

In addition to a physical examination, the following tests may be used to diagnose a neuroendocrine tumor:

• Blood/urine tests
• X-ray
• Computed tomography (CT or CAT) scan
• Magnetic resonance imaging (MRI)
• Biopsy
• Molecular testing of the tumor
• Positron emission tomography (PET) or PET-CT scan.

Treatments for Neuroendocrine Tumour

Treatment options and recommendations depend on several factors, including:

• The type of neuroendocrine tumor
• If it is cancerous and the stage
• Possible side effects
• The patient’s preferences and overall health

The most common treatment options for a neuroendocrine tumor are listed below:

• Surgery
• Radiation therapy
• Chemotherapy
• Targeted therapy
• Other medications
