Squamous cell carcinoma antigen, also known as SCC, is a subtype of tumor-associated antigen TA-4, which is a glycoprotein.
The normal value of SCC is <1.5 μg/L, and if it exceeds this value, the level is elevated, and its elevation is related to squamous cell carcinoma of the lung, esophagus, cervix and other diseases, and there is also a certain relationship between the concentration of SCC in serum and the stage of cervical squamous carcinoma, the size of the tumor, as well as the recurrence of the tumor and the progression of the disease.
Therefore, squamous epithelial cell carcinoma antigen can be used as one of the markers for monitoring the efficacy of treatment, prognosis evaluation and tumor recurrence. Although it can be related to many kinds of cancers, it cannot be diagnosed by a single index, and patients need to combine with esophageal microscopy, abdominal CT, pathological biopsy, etc. to make a definite diagnosis.
