[Serum carbohydrate 19-9 Tm and bronchial cancer. Comparative study with another tumor marker, carcinoembryonic...

Carbohydrate antigen 19-9 Tm (CA 19-9 Tm) level was measured in 3 groups of sera: 138 control subjects affected by bronchogenic no malignant diseases, 117 subjects with primary bronchogenic carcinoma, 43 with pulmonary metastasis of different cancers. Serum level CA 19-9 Tm was compared with serum level CEA. Control subjects bring us to state the discrimination standard between bronchogenic carcinoma and no carcinoma to 40 U/ml of CA 19-9 Tm. In primary bronchogenic carcinoma, a simultaneous increase of the two markers was noted in some subjects whereas in others only one tumor marker was increased pulmonary metastasis are considered. In these two cases, CEA increases more often in serum of subjects affected by adenocarcinomas CA 19-9 Tm and CEA are thus two different tumor associated markers.
