[Study of blood plasma from patients with rectal cancer using laser spectroscopy].
Laser correlation spectroscopy (LCS) was employed to evaluate blood-plasma indices in 82 patients with rectal malignancies. Twenty-one healthy donors were in control. Plasma homeostatitic indices in the study group were significantly altered due to lower light diffusion by elements larger than 100.0 nm. This points to lower immunocomplex-formation activity matched by low-molecular weight fraction (albular protein) reduction. There is a direct correlation between said changes and tumor progression. The LCS technique is useful in both early diagnosis of rectal cancer and formation of relevant groups at risk.
