STUDIES ON THE MEASUREMENT OF C.E.A. AND L.D.H. IN BIOPSIED LUNG SPECIMEN AND BRONCHIAL LAVAGED FLUIDS FROM THE PATIENTS WITH PRIMARY LUNG CANCER

Abstract

No significant difference of C.E.A. value was found between primary lung cancer and benign broncho-pulmonary diseases in tissues obtained by transbronchial lung biopsy. Even in the tissue obtained by surgery, C.E.A. values showed also no difference between lung cancer and other lung diseases. However, C.E.A. values in bronchial lavaged fluids were significantly higher in primary lung cancer than that of other lung diseases. Even if C.E.A. values in serum was normal, C.E.A. values in bronchial lavaged fluids was often high in patients of primary lung cancer. These findings suggest that the estimation of C.E.A. values in bronchial lavaged fluids has some supplemental benefit in diagnosis of lung cancer.
