title: [Indicators of thyroid hormones and carcinoembryonic antigen in persons with a high risk of lung cancer].
abstract: An attempt was made to study CEA and thyroid hormones in high risk groups as there is evidence of their change in lung cancer patients. A questionnaire to distinguish between 4 types of the probability of lung cancer development and a method of radioconcurrent analysis to study the concentration of CEA and thyroid hormones in the blood serum were used. A high risk group included 320 practically healthy persons, a control group 108 patients with verified lung cancer. The results of the study have shown that the concentration of CEA and thyroid hormones increases more often in persons of the high risk group with noncancerous diseases than in persons without pathological pulmonary changes. With an increase in the degree of probability the frequency of a high concentration of CEA and thyroid hormones grows. The older the persons with a high risk of lung cancer, the higher the frequency of concentration of the thyroid hormones. Studies of CEA and thyroid hormones can be used for dynamic observation of persons with a high risk of lung cancer.
