Lung adenocarcinoma is one of the common malignant tumors in the lungs, which can be initially judged by tumor markers, the main tumor markers include cea, ca125, ca153 and so on.
1. cea: also known as carcinoembryonic antigen, is a broad-spectrum tumor marker, which rises significantly during the development of lung adenocarcinoma and has a certain suggestive effect.
2. ca125: also known as glycan antigen 125, it has certain specificity for lung adenocarcinoma antigen, and the value of it rises significantly higher than that of other lung malignant tumors in the process of lung adenocarcinoma.
3. ca153: also known as glycan antigen 153, which is highly expressed in all kinds of adenocarcinomas and has certain specificity for the diagnosis of lung adenocarcinoma.
The rise of tumor markers combined with the masses in the lungs can determine the possibility of lung adenocarcinoma, and the final diagnosis needs to be made by puncture biopsy and standardized treatment under the guidance of clinicians.
