The serum levels of carcinogenic embryonic antigen (CEA), SCC, Cyfra 21-1, and ProGRP were studied in 57 primary patients with Stages I-IV LC of various histological types (squamous-cell and small-cell carcinoma, adenocarcinoma), in 12 patients with noncancer lung diseases, and in 13 healthy individuals. The highest sensitivity was demonstrated by the combined determination of Cyfra 21-1 and SCC for squamous-cell LC (88.2%) and that of CEA and Cyfra 21-1 for lung adenocarcinoma (57.1%). On a small sample of patients, the new serological marker ProGRP showed not only a high sensitivity (75%) for small-cell LC, but also a high specificity (94.3%) for non-small-cell LC. These results agree with few data in the foreign literature and suggest that the marker should be used for the specifying differential diagnosis of small-cell LC and the monitoring of patients with type of LC.ProGRPSCCCyfra 21-1lung cancertumor-associated markerProGRPSCCcarcinogenic embryonic antigenCyfra 21-1рак легкогоопухолеассоциированный маркерРЭА[European Group on Tumor Markers: Consensus recommendations // Anticancer Res. - 1999. - Vol. 19, N 4A. - P. 2789- 2819.][Faten-Moghadam A., Stieber P.
