There are many lung tumor markers, such as CEA (carcinoembryonic antigen), CYFRA21-1 (human cytokeratin 21-1 fragment), NSE (neuron-specific enolase), CA125 (glycan antigen 125) and so on.
1.CEA: CEA assay can be used for clinical detection of lung tumors, can continuously monitor the level of CEA, as well as help to observe the efficacy of tumor treatment and prognosis, belongs to a kind of lung tumor markers.
2. CYFRA21-1: CYFRA21-1 is mainly a soluble fragment of cytokeratin 19, which is mainly used for the detection of lung cancer tumor markers, and is of great significance for the diagnosis of lung cancer.
3. NSE: NSE is of great significance in monitoring the condition, therapeutic effect and prognosis of small cell lung cancer, and it is a tumor marker with high specificity and sensitivity.
4. CA125: CA125 is a glycoprotein from the epithelial cells in the body cavity and can be expressed in normal tissues, it can be used as a tumor marker, if there is a lung tumor in the body, the value of CA125 may be abnormal.
For lung tumor patients, there are many tumor markers that can be used as tumor markers, it is recommended that patients go to regular hospitals in time, and standardize the treatment under the guidance of doctors.
