title: Predictive value of SCC-Ag, CYFRA 21-1 and selected acute phase proteins in radiotherapy of pharyngeal and laryngeal cancer. A preliminary report.
abstract: The diagnostic sensitivity and specificity of tumor markers in head and neck cancers is not satisfactory. It is a stimulus for search of other biochemical indicators, among others determinations of acute phase proteins, helpful in head and neck cancers diagnostics and prognosis. In a group of 33 patients with squamous cell carcinoma of the pharynx and larynx (T1-4 N0-3 M0) CYFRA 21-1, SCC-Ag and acute phase proteins such as prealbumin, albumin, alpha-1 acid glycoprotein, alpha-1 antytrypsin, transferrin, ceruloplasmin and C-reactive protein (CRP) determinations were performed before radiotherapy. Significantly greater area under ROC curve for CYFRA 21-1 than for SCC-Ag was found. In T3-4 group, significantly lower albumin and higher AAG and CRP concentrations in comparison with T1-2 patients were observed. Multivariate analysis revealed that apart from tumor stage, elevated concentrations of SCC-Ag and/or CRP are independent unfavorable prognostic factors.
