| description | Aim. To identify single nucleotide polymorphisms reliably associated with cardiovascular toxicity in oncohematological patients receiving antitumor immunochemotherapy.Material and methods. For the study, 34 patients with an established diagnosis of non-Hodgkin's B-cell follicular lymphoma were prospectively selected at the Clinic of the Samara State Medical University, who were indicated for antitumor immunochemotherapy according to the R-CHOP protocol. During the follow-up, the patients were divided into 2 following groups: the main group consisted of 12 patients with cardiovascular toxicity (mean age, 42,4 (2,8) years, including men — n=3 (25%)), the control group — 22 patients without cardiovascular toxicity (mean age, 39,8 (1,7), including men — n=8 (36%)). Cardiovascular toxicity was verified on the basis of a combination of specific cardiological complaints with a decrease in the left ventricular ejection fraction >10% from the baseline or in absolute terms less than 53% and/or a decrease in the left ventricular longitudinal systolic strain >12% from the baseline and/or an increase in NT-proBNP >125 pg/ml.Results. The study presents the identified genetic features in oncohematological patients in the context of cardiovascular toxicity. ABCC5 rs1879257, PRKAG2 rs13224758, RYR2 rs10925391 and SLC22A7 rs414917 variants had a significant association with an increased risk of cardiovascular toxicity in the target group of patients by 5-6 times. In addition, the ABCB1 rs2032582 variant showed the opposite effect and was associated with a reduced risk of cardiovascular complications, having a protective effect on the cardiovascular system.Conclusion. Although further studies are needed to confirm the diagnostic and prognostic significance of the detected genetic variants, the study results indicate the prospects of genetic screening before antitumor immunochemotherapy as a future tool for stratifying oncohematological patients and minimizing cardiovascular toxicity. |
