    Cardiovascular toxicity is one of the important problems of clinical oncology. Atherosclerosis progression was demonstrated in patients with cancer and chemotherapy. The aim - to evaluate the vascular wall characteristics and to determine the predictors of AS of brachiocephalic arteries progression during anticancer therapy in patients with breast cancer. Methods. The study involved 43 patients with newly diagnosed breast cancer (BC) (II-III stage) with overexpression of HER2; median age 50 (40;57) years. All patients underwent neoad-juvant drug therapy with antracyclines, taxanes and trastuzumab followed by surgery, radiation and hormone therapy according to the indications. Before anticancer therapy the general clinical examination was conducted and lipid profile, plasma lipoprotein (a) [Lp(a)] level, titres of autoantibodies IgM and IgG to lipoproteins and their oxidized derivatives were estimated. The vascular wall stiffness (pulse wave velocity on the carotid-femoral (PWVcf) and shoulder-ankle (PWVsa) segments, the central pressure, carotid intima-media thickness (CIMT) and the degree of stenosis of the brachiocephalic arteries) were determined at baseline and at each stage of anticancer therapy. The atherosclerosis progression was determined if the new stenosis (>= 15%) or increase of preexisting stenosis (>= 5%) were revealed; CIMT increase 0.1 mm. The parameters of cellular immunity (peripheral blood lymphocyte phenotyping via direct immunofluorescence and flow cytometry), lipid spectrum parameters, serum concentration of Lp (a), autoantibodies IgM and IgG against lipoproteins and their oxidized derivatives, as well as PWVcf and PWVsa were assessed in 17 BC patients before the onset of neoadjuvant therapy and in 20 healthy women. Results. BC patients and healthy women were comparable in traditional cardiovascular risk factors but differed in PWVsa and PWVcf levels (p <0.05). In BC patients the activation of T-cell immunity with the stimulation of both subpopulations with pro-inflammatory and regulatory properties was observed (p<0.05). The direct correlations between the content of activated T-lymphocytes (Th-act), T-helpers (Th) 1 and PWVsa (p<0.05), as well as Th-act, Th1 and Th2 and PWVcf (p<0.05) were revealed in the general group. The decrease of systolic blood pressure (SBP), central SBP (SBPc), central diastolic blood pressure (DBPc), PWVcf and PWVsa levels accompanied with a temporary heart rate increase were observed during anticancer therapy; SBP, SBPc, PWVcf levels restored by the end of the follow-up period. The CIMT increase was detected in 22 (51%), and the atherosclerosis progression in 26 (60%) BC patients during anticancer therapy. Lp (a) level above 12.8 mg/dl was associated with CIMT increase (p <0.05). Age > 48 years and radiation therapy were risk factors for CIMT increase and atherosclerosis progression (p<0.05), respectively. Conclusions. The vascular stiffness is increased in BC patients, which is associated with the activation of effector subpopulations of T-lymphocytes and the elevation of circulating level of both pro-atherogenic and anti-atherogenic T-cells. The level of Lp (a) above 12.8 mg/dl is associated with atherosclerosis progression, which requires further research. Age and radiation therapy are the risk factors for atherosclerosis progression during anticancer therapy.
