Abstract

Anthracycline chemotherapy serves an important role in treating patients with breast cancer but is associated with cardiotoxicity. Although brain natriuretic peptide (BNP) is not the ideal marker for detecting the presence of diseases of the heart, several studies have demonstrated the predictive utility of BNP in the diagnosis of anthracycline‑induced cardiotoxicity (AIC). The aim of the present study was to evaluate the role of BNP as a marker for the early prediction of AIC in patients with breast cancer. In the present study, a total of 149 patients with breast cancer who received anthracycline therapy were evaluated. The levels of BNP and echocardiography were detected during the anthracycline‑based chemotherapy and patients were followed up after chemotherapy to determine the cardiotoxicity‑free survival times. In the patients who received chemotherapy, an increase in the levels of BNP was observed. The concentration of BNP was significantly higher in the cardiotoxicity group during anthracycline chemotherapy (P=0.022) compared with the non‑cardiotoxicity group and it was an independent predictor of cardiotoxicity (P=0.028). The optimal diagnostic threshold of BNP after the last anthracycline chemotherapy treatment was 107.9 pg/ml, the diagnostic sensitivity was 0.538, the specificity was 0.794, the Youden index was 0.332, the positive predictive value was 0.583 and the negative predictive value was 0.762. Based on the BNP threshold, a log‑rank test was performed and it was determined that the cardiotoxicity‑free survival rate of the group with higher levels of BNP was always lower compared with the group with lower levels of BNP. BNP elevation was associated with cardiotoxicity during the anthracycline chemotherapy. Detecting BNP after the final treatment of anthracycline chemotherapy may contribute to the early detection of cardiotoxicity.
