Purpose: to improve the diagnosis of relapse and metastasis of breast cancer in the postoperative period. Material and methods. 123 women were examined. Of these, 30 practically healthy women made up a control group, 20 women had benign breast diseases, 73 had breast cancer. The patients with ВС before the surgical intervention were divided into groups according to the stage of the disease. The 1st group consisted of 30 practically healthy women. In the second group — 20 women with fibroadenomas of the breast. In the third group — 33 women with l-ll stages of breast cancer without regional metastases. The 4th group consisted of 22 women with stage II breast cancer with regional metastases, in the 5th group — 18 patients with stage III breast cancer. After surgery, 68 patients were re-examined and divided into 2 analytical groups. The 6th group included women without clinical manifestations of relapses and metastases in the postoperative period — 44 (64.7%). Group 7 consisted of 24 (35.3%) women who had metastasis and local recurrences of the disease in the postoperative period. To determine the content of fetal proteins (Ca-15-3, Ca-125, REA), IL-8 and VEGF, commercial sets of reagents for solid-phase enzyme-linked immunosorbent assays were used. Results. Analysis of the data obtained showed that the most significant increase in serum and plasma VEGF levels occurred in breast cancer patients with clinical signs of metastasis and recurrence of the disease. Of fetal proteins, a significant increase in blood content showed Ca15-3 and CEA. Conclusion. We can assume that in patients with breast cancer only in the postoperative period, the rise in VEGF was associated with the growth of tumor tissue and the development of invasion and metastasis.
