[Squamous cell carcinoma antigen (Scc-Ag): diagnostic utility in squamous cell carcinoma antigen of the head and neck with metastasis to lymph nodes].

Aim of the work was estimation of squamous cell carcinoma antigen (SCC) concentrations in serum and qualification its diagnostic value in patients with malignant neoplasm of head and neck in dependence from presence of metastasis to lymphatic glands. The study comprised the group of 146 persons (108 with head and neck malignant neoplasm, 38 of persons determined group supervisory). At 35 ill one ascertained metastasis to lymph nodes. In presented work sensitivity of SCC in initial investigation was (52.8%), specificity (97.4%), positive predicting value (PV+ = 94.2%) and negative predicting value (PV- = 64.0%). We observed not characteristic statistical dependence of concentrations SCC from presence of metastasis to lymph nodes. There was characteristic correlation between concentration of SCC and presence of metastasis to regional lymphatic glands using of correlation R-Spearman.
