title: [An evaluation of carcinoembryonic antigen (CEA), beta 2-microglobulin (BMG), and immunosuppressive acidic protein (IAP) in the serum of primary lung cancer patients].
abstract: The correlation between histological type and serum CEA, BMG, and IAP was studied in 98 patients with primary lung cancer. In particular, the results showed that the positive ratio in squamous cell carcinoma was increased by measuring serum BMG or IAP simultaneously with serum CEA more than by measuring serum CEA alone. Also, when these values were compared with histological type, adenocarcinoma showed an elevation of the serum CEA level, whereas squamous cell carcinoma showed an elevation of the serum BMG or IAP level. It was suggested that serum CEA, BMG and IAP levels were closely correlated with the histological type in primary lung cancer.
