[The prospects of laser correlational spectroscopy in differential diagnosis of breast tumors and extreme cases in surgery].

The application possibility of the biophysical method laser correlational spectroscopy (LCS), permitting to obtain the information concerning the assortment of lightdispersing particles of different sizes, was studied up looking for a new approaches to trustful differential diagnosis of oncological diseases. Using the LCS method 57 healthy persons, 83 patients with the mammarial gland (MG) tumor, 26 with profuse abdominal bleeding, 32 with polytrauma, 68 in comatous state were examined. The histograms of the patients with MG cancer differed with such of the patients with benign MG tumor.

LCS presents information on the size distribution of particles in analysed objects. LCS of blood plasma was performed in 26 patients with stomach bleedings, 19 with brain injuries, 13 with chronic hepatitis, 149 with chronic chlorophos intoxication and 45 healthy subjects. Spectra of blood plasma from patients with stomach bleeding differed significantly from those of healthy subjects.

[The subfractional composition of the blood plasma in benign tumors and cancer of the breast based on the data from laser correlational spectroscopy].

LCS was performed in 35 patients with mammary cancer, 59 patients with benign breast tumours and 35 healthy people. 39 samples were taken from inhabitants of Odessa, 89 from St.-Petersburg.
