Tetranectin as a potential novel prognostic biomarker in anthracycline-related cardiac dysfunction

To assess the association of serum tetranectin levels with cardiac remodeling parameters and to evaluate its prognostic role in women with anthracycline-related cardiac dysfunction (ARCD) and without previous cardiovascular diseases (CVD) during 24-month follow-up period. A total of 362 women with primary diagnosed breast cancer who were planned to be treated with anthracyclines were examined. At 12 months after chemotherapy completion, all women were examined and ARCD was diagnosed in 114 patients. After 24 months of follow-up, all patients with ARCD were divided into 2 groups: group 1 comprised women with the adverse course of ARCD (n = 54), group 2 comprised those without it (n = 60). In group 1, the levels of tetranectin were lower than group 2 by 27.6% (p < 0.001) and the patients without ARCD by 33.7% (p < 0.001). In group 1, the levels of tetranectin decreased (p < 0.001) from 11.8 (7.1; 14.3) to 9.02 (5.3; 14.6) pg/mL at 24 months. Moreover, in group 2 (p = 0.871) and in patients without ARCD (p = 0.716), they did not change. The tetranectin values were the independent predictor (odds ratio 7.08; p < 0.001) and its levels ≤ 15/9 ng/mL (AUC = 0.764; p < 0.001) were identified as the predictors for the adverse course of ARCD. NT-proBNP levels did not show the prognostic role, but the addition of NT-proBNP improved prognostic value of analysis (AUC = 0.954; p = 0.002). The cut-off values of tetranectin were established as predictor for adverse course of ARCD, when NT-proBNP was not. The combined use of tetranectin and NT-proBNP demonstrated higher diagnostic value for prediction of adverse outcomes.
