Supplementation in suppressing Troponin I and NT-proBNP level in breast cancer patients with 5- fluorouracil, adriamycin, and cyclophosphamide chemotherapy

Background: Breast cancer is a malignancy originating from breast tissue, where chemotherapy is one of the choice therapy. Doxorubicin, 5-fluorouracil, and cyclophosphamide (FAC) are the most commonly used combination of chemotherapy. One of the side effects of chemotherapy is cardiotoxicity. Multiflora honey prevents cardiotoxic effects through its flavonoids and polyphenols compounds. The aim of this research is to analyze the effectiveness of adding honey in preventing cardiotoxic effects in breast cancer patients receiving FAC chemotherapy. Methods: An experimental study with double-blind randomized pre and post-test with control group design. Ductal invasive breast cancer patients were divided into 2 groups, the control group, who received FAC chemotherapy (n=18) and the treatment group, who received chemotherapy and 90 ml/day honey consumption for 14 days (n=18). The patient's Troponin I and NT-proBNP enzyme levels before and after 14 days of the study were assessed. Results: Post-treatment, there was an increase in Troponin I levels from the treatment group (0.22 ± 0.07 vs. 0.24 ± 0.07) vs. control (0.25 ± 0.11 vs. 0.34 ± 0.20) with a significant difference. (p = 0.031). There was a decrease in NT-proBNP levels in the treatment group (461.0 ± 610.4 vs. 215.6 ± 260.3) and an increase in NT-proBNP levels (275.9 ± 392.4 vs. 315.4 ± 293.9) with a significant difference (p = 0.006). Conclusion: Multiflora honey can prevent cardiotoxic effects in breast cancer patients receiving FAC chemotherapy.
