Studies of the hypophyseal-thyroid system in patients with cancer of the lung, stomach, mammary gland have revealed similar changes, manifested in the increased TTH concentration with simultaneous fall in the T3 and T4 content with the resultant increase of TTH/T3 and TTJ/T4 coefficients. The changes observed are characteristic of oncological patients only and may be used for diagnostic purposes.
