[Indicators of thyroid hormones and carcinoembryonic antigen in persons with a high risk of lung cancer].

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.

[Cytology of large cysts of the breast].

Cytological examinations of punctates of 200 large mammary gland cysts distinguished three variants thereof: cysts without signs of epithelium proliferation; cysts with signs of epithelium proliferation; and cysts with signs of epithelium proliferation and atypia. In 12 operated patients with the cyst of the second variant no cancer was detected. Among 9 operated patients with cysts of the third variant 3 were found to have intraductal cancer with initial invasion (including one case of malignized cystadenopapilloma).
