Abstract

Objective

The usefulness of pretreatment measurement of SCC antigen in patients with head and neck SCC is still controversial. Our aim of this study was to evaluate the clinical usefulness of serum SCC antigen, SCCA1 and SCCA2 in the management of patients with head and neck SCC.

Methods

Serum samples for the analysis of SCCA1, SCCA2 and SCC antigen were taken from head and neck SCC patients before treatment. Serum SCC antigen was assayed with a solid phase immunoradiometric assay. The SCCA1 and SCCA2 protein level was determined by a sandwich ELISA.

Results

Fifty-two of 96 cases (54%) showed evaluated serum SCC antigen levels above the upper limit. The serum SCCA2 level was significantly higher in the head and neck SCC patients than in control group, whereas there were no significant differences in the serum SCCA1 level between head and neck SCC patients and control group. 72% of head and neck SCC patients demonstrated SCCA2 levels higher than 0.15, whereas 68% of the control subjects had SCCA2 levels less than 0.15.

Conclusion

The serum SCCA2 levels were increased during the progression of cancer and might be a useful tool for the management of head and neck SCC.
