CARDIOTOXICITY RISK PREDICTION IN BREAST CANCER PATIENTS

Breast cancer patients receive combined antitumor treatment (surgery, chemotherapy, targeted drugs and radiation), so they are considered to be the patients with potentially high risk of cardiotoxicity (CT). Risk stratification of cardiovascular complications before the beginning and during the cancer treatment is an important issue.
Objective: to develop a CT risk model score taking into account cardiological, oncological and individual risks.
Material and methods. The study included 52 breast cancer patients with retrospective analysis of their medical history, risk factors, and echocardiographic parameters before the onset and in 12 months follow up. Based on the analysis of the data, a CT risk model score was developed and recommended. The patients were divided into groups according to the score: Group 1 low risk of CT development score ≤ 4 points, Group 2 moderate risk 57 points, Group 3 high risk ≥ 8 points. According to the scale, BC patients with a total of ≥ 8 points are considered to be at high risk for CT complications. Radiation therapy and anthracyclines, as well as associated cardiovascular diseases were the most important risk factors of CT.
Results. Based on the study of retrospective analysis of risk factors, data of heart function monitoring during follow-up, the risk model score of cardiotoxicity has been developed for the BC patients stratification. According to the proposed score risk model, BC patients with a total score of ≥ 8 points considered to have high risk of cardiotoxic complications.
Conclusions. Using of the proposed risk model score with calculation of CT risk factors both before the beginning and during cancer therapy is important, because it allows predicting the risk of CT development to identify highrisk patients, accordingly, to develop an individualized plan for cardiac function monitoring and to start timely cardioprotective therapy.
Key words: breast cancer, cardiotoxicity, heart failure, risk scale, prognosis.
