Report
Neuroendocrine tumours are rare and can occur anywhere in the body. Most common sites are lungs, appendix, small intestine, rectum and pancreas. These tumours often cause abnormal production of hormones impacting important functions. The diagnosis or initial screening is done by certain cancer marker tests. Cancer markers or tumour markers are proteins produced by the normal cells as well as cancer cells, but are produced in higher levels by the cancer cells. Cancer marker profile (Neuroendocrine tumors) consists of tests to measure the levels of tumour markers in the blood. This profile test may be useful in the screening of certain endocrine cancers and decide the treatment prognosis. Diagnosis or treatment of neuroendocrine tumours depend on the type, location and hormone production.

The Cancer marker profile (Neuroendocrine tumors) measures the Chromogranin A, and NSE levels in the blood.
- This test is useful for the screening of neuroendocrine tumors. It should however not be used in isolation for the diagnosis of tumours.
- The profile tests can be used for monitoring treatment and relapse in patients with hormone dependent tumours.
- The test may be used as a prognostic marker for survival following certain surgeries.
- To know the stage of cancer as well as the metastasis status
- The test can help detect recurrence, metastasis and residual cancer.
Neuroendocrine tumours may not produce any symptoms in the initial stages. Depending on the size of the tumour, its location and hormonal activity it may produce the following general signs and symptoms:
- Headache [radiating or non-radiating]
- Pain, numbness and muscle weakness [due to facial nerve impingement]
- Nausea, vomiting
- Seizures
- Diarrhoea
- Skin flushing
- Dizziness
This test requires a blood sample. A tourniquet (elastic) band is placed tightly on the upper arm. The patient is then asked to make a fist. This helps in the build-up of blood filling the veins. The skin is disinfected before needle insertion and the blood sample is collected in vacutainer.
