[Radionuclide evaluation of postoperative catabolism in breast cancer]

The paper is concerned with the results of investigation of the body composition and albumin circulation using a method of whole-body radiometry, extracellular liquid volume--by a 40K-RP, the level of cortisol, T3, insulin, C-peptide in the blood plasma by a radioimmunoassay in 30 breast cancer patients. A decrease in cellular body mass, an increase in extracellular body mass and total body fat, a decrease in the sizes of all pools and albumin synthesis rate were revealed before the initiation of specific cancer therapy. Ten days after the discontinuation of therapy the above indices returned to normal.
