Abstract
PURPOSE OF STUDY: An association of squamous cell carcinoma antigen (SCC-Ag) level with cancer prognosis has been reported in many studies. Our investigators conducted the first study determining a correlation between the SCC-Ag level and the tumor volume in head and neck cancer. PROCEDURES: The SCC-Ag level of patients were measured from the serum, whilst the tumor volume was calculated by the ellipsoid formula and verified by logistic software on radiology. The correlation between SCC-Ag level and tumor volume was analyzed. RESULTS: Fifty-two patients were studied, with the mean age of 62.4 years. Tumor types were: oral cavity cancer (11 cases, 21.6%), oropharyngeal cancer (21 cases, 40.38%), hypopharyngeal cancer (8 cases, 15.7%), and laryngeal cancer (12 cases, 23.5%). Mean tumor volume was 20.01 mL (range 0.02-91.46 mL). Mean SCC-Ag level was 2.69 ng/mL (range 0.5-14.6 ng/mL). The critical point of SCC-Ag was 5.8 ng/mL. The Pearson's correlation coefficient between SCC-Ag level and tumor volume was 0.524 (p = 0.0002). CONCLUSIONS: SCC-Ag moderately correlates with tumor volume in head and neck cancer patients, with statistical significance. We suggest that using tumor volume, rather than a one-dimensional measurement such as tumor size, to analyze correlation with SCC-Ag offers a more accurate means of cancer prognosis.
