[Clinical study on the measurement of squamous cell carcinoma (SCC)--related antigen in SCC].

By using a RIA Kit for squamous cell carcinoma (SCC) antigen, extracted and purified this substance from liver metastasis of SCC of the uterine cervix, a fundamental and clinical study has been done. Based on the fundamental study, it was shown that this kit was useful clinically. High concentrations of serum SCC related antigen were observed in squamous cell carcinoma of the lung, head and neck, and uterus. It was recognized that the measurement of serum SCC related antigen was useful in not only diagnosis, but also in the evaluation of effectiveness of therapy or prediction of recurrence. In particular, as there is a lack of reliable tumor markers in head and neck tumors, good results can be anticipated from the measurement of SCC related antigen in such cases.
