NSE (Neuron-Specific Enolase)
*What is NSE?
NSE (Neuron-Specific Enolase) is a glycolytic enzyme primarily found in neuroendocrine cells and neurons. When these cells are damaged or undergo malignant transformation, NSE may be released into the bloodstream, making it a useful tumor marker.
*Normal Range: <16.3 ng/mL (Values may vary depending on laboratory standards.)
*Clinical Significance of NSE
NSE is mainly used for the diagnosis and monitoring of neuroendocrine tumors, especially small cell lung cancer (SCLC) and neuroblastoma.
*Possible Causes of Elevated NSE
-Small Cell Lung Cancer (SCLC): NSE elevation is associated with SCLC and can be used for diagnosis, prognosis evaluation, and treatment monitoring.
-Neuroblastoma: NSE can serve as a diagnostic and therapeutic response marker.
-Other Neuroendocrine Tumors (e.g., insulinoma, pheochromocytoma, carcinoid tumors): NSE may be elevated.
-Central Nervous System (CNS) Injury: Conditions such as traumatic brain injury, hypoxic brain injury, and stroke may cause NSE elevation, though it is not tumor-specific.
-Renal Dysfunction: Impaired NSE metabolism can lead to increased NSE levels.
*Limitations of NSE
NSE is not a specific tumor marker. Other non-cancerous conditions (e.g., brain injury, renal failure) can also cause NSE elevation. NSE alone cannot diagnose cancer. It should be interpreted alongside imaging studies (e.g., CT scan, MRI) and biopsy results.
*Conclusion
NSE is an important marker for small cell lung cancer (SCLC) and neuroblastoma, aiding in diagnosis, prognosis assessment, and treatment monitoring. NSE is not a highly specific tumor marker and should be analyzed in conjunction with other clinical examinations. If NSE levels are elevated, further evaluation by a physician is necessary to determine whether the cause is a tumor or another neurological condition.
