ORLANDO – Anthracycline chemotherapy was associated with a cardiotoxicity incidence of roughly 14% of breast cancer patients regardless of treatment with carvedilol, based on data from a randomized trial of 200 patients.
“Cardio-oncology has been neglected,” Monica Samuel Avila, MD, of Hospital das Clínicas da Faculdade de Medicina da Universidade in São Paulo, Brazil, said in a video interview at the annual meeting of the American College of Cardiology. “We have seen improvement of survival in patients with cancer, but with that comes complications related to treatment. I think that the interactions between cardiologists and oncologists are increasing in a more important way,” she said.
In the Carvedilol for Prevention of Chemotherapy-Induced Cardiotoxicity (CECCY) Trial, Dr. Avila and colleagues evaluated primary prevention of cardiotoxicity in women with normal hearts who were undergoing chemotherapy for breast cancer.
Patients in the treatment group received a median carvedilol dose of 18.4 mg/day. The primary endpoint of cardiotoxicity, defined as a decrease in left ventricular ejection fraction (LVEF) of at least 10% at 6 months, occurred in 15% of carvedilol patients and 14% placebo patients, a nonsignificant difference. No significant differences occurred in diastolic dysfunction or in B-type natriuretic peptide (BNP) levels at 6 weeks, 12 weeks, or 24 weeks between the groups.
However, carvedilol patients showed significantly reduced troponin 1 levels compared with placebo, which suggests protection against myocardial injury, Dr. Avila said.
“In short follow up, we can see cardiotoxicity appearing, and we know we have to treat it promptly to prevent cardiac events,” she said.
Dr. Avila and colleagues identified 200 women older than 18 years with HER2-negative breast cancer tumor status and normal left ventricular ejection fraction. The patients were undergoing chemotherapy with 240 mg/m2 of anthracycline and were randomized to treatment with carvedilol or a placebo. Baseline characteristics were similar between the two groups.
Adverse effects were not significantly different between the groups, and the most common events in each group included dizziness, dry mouth, symptomatic hypertension, stomachache, and nausea. Although the results suggest that carvedilol can reduce the risk of myocardial injury, more research is needed to address the question of the increase in troponin without change in the LVEF, Dr. Avila noted. The study is ongoing and the research team intends to follow the low-risk patient population for a total of 2 years. “For high-risk patients, I am already giving carvedilol,” she said. “We believe if we find a difference in LVEF or clinical events, we could encourage cardiologists to give carvedilol in a low-risk population,” she said.
“This study highlights that there is no safe dose of anthracycline,” commented Bonnie Ky, MD of the University of Pennsylvania, Philadelphia, at a press briefing. She emphasized the value of carvedilol for a high-risk population, and stressed the importance of following long-term changes in heart injury markers after 1-2 years for low-risk patients.
Dr. Avila had no financial conflicts to disclose. Dr. Ky disclosed relationships with multiple companies including Bioinvent and Bristol Myers.
The findings were published simultaneously in the Journal of the American College of Cardiology.
