Squamous cell carcinoma antigen levels in patients with different stages of laryngeal cancer.
An attempt was undertaken to evaluate the usefulness of squamous cell carcinoma antigen (SCC Ag) in different stages of squamous cell carcinoma of the larynx. Antigen levels were determined in blood serum before treatment in 25 patients with laryngeal cancer treated at the II ENT Department, Silesian Medical School in Zabrze. Ages were 39-65 years (mean, 56.6 years). Fifteen healthy volunteers of similar ages served as controls. SCC Ag was estimated by an enzyme-immunological method using the Abbot set. Increasing levels of SCC Ag were found in 14 patients (65%). The mean SCC Ag level before treatment in the tumor group was 2.93 +/- 0.23 ng/ml and 0.79 +/- 0.19 ng/ml in the control group (standard, 1.5 ng/ml). Mean SCC Ag levels depending on the clinical stage of disease were: stage I, 1.52 ng/ml; stage II, 2.16 ng/ml; stage III, 3.03 ng/ml; stage IV, 4.57 ng/ml. Differences in all groups were statistically significant when compared to the healthy controls (P < 0.05).
