[Unsaturated blood lipids in breast cancer patients].

The degree of unsaturation of blood lipids in patients having undergone radical surgery for mammary cancer was studied. It was shown that the content of double bonds in the lipids of plasma and red cells in cancer patients is significantly lower than in patients with diffuse cancer but higher than in patients with benign breast tumors. It was also established that there exists a relationship between the degree of lipid unsaturation, the tumor spread (stage of the disease, metastases into the regional lymph nodes), and also patient survival. Variations in the double-bond level of blood lipids depending on the morphological structure of the tumor were established.
