Effect of standard low-dose anthracycline chemotherapy on late congestive heart failure in breast cancer survivors aged between 50 and 59 at diagnosis: A nationwide study.

ABSTRACT:

Objectives

Although chemotherapy-induced congestive heart failure (CHF) is a well-known adverse event in cancer survivors, the long-term risk of standard low-dose anthracycline has not yet been reported. This study aimed to investigate the long-term effects of standard anthracycline on late CHF in breast cancer survivors.

Materials and methods

A nationwide retrospective cohort study was conducted using the national insurance claims data for nearly 98% of Korean citizens. Between Jan 2010 and Dec 2015, a total of 56,338 newly diagnosed female breast cancer survivors were included.

Results

The total number of person-years was 199,648 and the incidence rate of late CHF was 3.57 per 1000 person-years. In multivariate analysis according to the subject's age at diagnosis, only in the 50-59 age group, anthracycline-based [hazard ratio (HR) 1.765, 95% confidence interval (CI) 1.206-2.583] and taxane plus anthracycline-based regimens (HR 1.816, 95% CI 1.192-2.768) significantly increased the risk of late CHF. In the 50-59 age group, standard low-dose anthracycline significantly increased the risk of late CHF (HR 1.627, 95% CI 1.080-2.451) in Cox proportional hazard regression models. In competing risk model with recurrence and in-hospital death as competing risks, standard low-dose anthracycline was a significant risk factor for late CHF [subdistribution hazard ratio (SHR) 1.553, 95% CI 1.029-2.340].

Conclusion

This nationwide study showed that standard chemotherapy with low-dose anthracycline is a risk factor for late-onset CHF in breast cancer survivors who were in their 50 s at breast cancer diagnosis. Long-term monitoring of late CHF should be considered in these younger breast cancer survivors.

Project description:ImportanceChemotherapy exposure is a known risk factor for cancer-related cognitive impairments. Anthracycline-based regimens are commonly used chemotherapies that have been shown to be associated with cognitive impairment and brain changes in clinical studies.ObjectiveTo directly compare the effects of anthracycline and nonanthracycline regimens on cognitive status and functional brain connectivity.Design, setting, and participantsIn this observational study, we retrospectively examined cognitive and resting state functional magnetic resonance imaging data acquired from 62 primary breast cancer survivors (mean [SD] age, 54.7 [8.5] years) who were more than 2 years off-therapy, on average. Twenty of these women received anthracycline-based chemotherapy as part of their primary treatment, 19 received nonanthracycline regimens, and 23 did not receive any chemotherapy. Participants were enrolled at a single academic institution (Stanford University) from 2008 to 2014, and the study analyses were performed at this time.Main outcomes and measuresCognitive status was measured using standardized neuropsychological tests, and functional brain connectivity was evaluated using resting state functional magnetic resonance imaging with a focus on the brain's default mode network.ResultsThe anthracycline group demonstrated significantly lower verbal memory performance including immediate recall (F = 3.73; P = .03) and delayed recall (F = 11.11; P < .001) as well as lower left precuneus connectivity (F = 7.48; P = .001) compared with the other 2 groups. Patient-reported outcomes related to cognitive dysfunction (F = 7.27; P = .002) and psychological distress (F = 5.64; P = .006) were similarly elevated in both chemotherapy groups compared with the non-chemotherapy-treated controls.Conclusions and relevanceThese results suggest that anthracyclines may have greater negative effects than nonanthracycline regimens on particular cognitive domains and brain network connections. Both anthracycline and nonanthracycline regimens may have nonspecific effects on other cognitive domains as well as certain patient reported outcomes. Further research is needed to identify potential methods for protecting the brain against the effects of various chemotherapeutic agents.

Project description:BackgroundThe National Comprehensive Cancer Network and American Society of Clinical Oncology recommend consideration of the use of echocardiography 6 to 12 months after completion of anthracycline-based chemotherapy in at-risk populations. Assessment of BNP (B-type natriuretic peptide) has also been suggested by the American College of Cardiology/American Heart Association/Heart Failure Society of America for the identification of Stage A (at risk) heart failure patients. The real-world frequency of the use of these tests in patients after receipt of anthracycline therapy, however, has not been studied previously.Methods and resultsIn this retrospective study, using administrative claims data from the OptumLabs Data Warehouse, we identified 31 447 breast cancer and lymphoma patients (age ≥18 years) who were treated with an anthracycline in the United States between January 1, 2008 and January 31, 2018. Continuous medical and pharmacy coverage was required for at least 6 months before the initial anthracycline dose and 12 months after the final dose. Only 36.1% of patients had any type of cardiac surveillance (echocardiography, BNP, or cardiac imaging) in the year following completion of anthracycline therapy (29.7% echocardiography). Surveillance rate increased from 37.5% in 2008 to 42.7% in 2018 (25.6% in 2008 to 40.5% echocardiography in 2018). Lymphoma patients had a lower likelihood of any surveillance compared with patients with breast cancer (odds ratio, 0.79 [95% CI, 0.74-0.85]; P<0.001). Patients with preexisting diagnoses of coronary artery disease and arrhythmia had the highest likelihood of cardiac surveillance (odds ratio, 1.54 [95% CI, 1.39-1.69] and odds ratio, 1.42 [95% CI, 1.3-1.53]; P<0.001 for both), although no single comorbidity was associated with a >50% rate of surveillance.ConclusionsThe majority of survivors of breast cancer and lymphoma who have received anthracycline-based chemotherapy do not undergo cardiac surveillance after treatment, including those with a history of cardiovascular comorbidities, such as heart failure.
