ABSTRACT

BACKGROUND: Clinical informatics tools to integrate data from multiple sources have the potential to catalyze population health management of childhood cancer survivors at high risk for late heart failure through the implementation of previously validated risk calculators.

METHODS: The Oklahoma cohort (n = 365) harnessed data elements from Passport for Care (PFC), and the Duke cohort (n = 274) employed informatics methods to automatically extract chemotherapy exposures from electronic health record (EHR) data for survivors 18 years old and younger at diagnosis. The Childhood Cancer Survivor Study (CCSS) late cardiovascular risk calculator was implemented, and risk groups for heart failure were compared to the Children's Oncology Group (COG) and the International Guidelines Harmonization Group (IGHG) recommendations. Analysis within the Oklahoma cohort assessed disparities in guideline-adherent care.

RESULTS: The Oklahoma and Duke cohorts both observed good overall concordance between the CCSS and COG risk groups for late heart failure, with weighted kappa statistics of .70 and .75, respectively. Low-risk groups showed excellent concordance (kappa > .9). Moderate and high-risk groups showed moderate concordance (kappa .44-.60). In the Oklahoma cohort, adolescents at diagnosis were significantly less likely to receive guideline-adherent echocardiogram surveillance compared with survivors younger than 13 years old at diagnosis (odds ratio [OD] 0.22; 95% confidence interval [CI]: 0.10-0.49).

CONCLUSIONS: Clinical informatics tools represent a feasible approach to leverage discrete treatment-related data elements from PFC or the EHR to successfully implement previously validated late cardiovascular risk prediction models on a population health level. Concordance of CCSS, COG, and IGHG risk groups using real-world data informs current guidelines and identifies inequities in guideline-adherent care.

Myocardial bridge in a patient with castration-resistant metastatic prostate cancer treated with enzalutamide

J Oncol Pharm Pract. 2023 Jun 6:10781552231180599. doi: 10.1177/10781552231180599. Online ahead of print.

ABSTRACT

INTRODUCTION: Myocardial bridge is a morphological anomaly of the heart characterised by the presence of a myocardial segment above a coronary artery, which results in a higher risk of cardiovascular events. In patients with prostate cancer treated with androgen receptor-targeted agents, a higher risk of cardiotoxicity was observed.

CASE REPORT: An 88 years old man with metastatic castration-resistant prostate cancer in treatment with enzalutamide, denosumab, and triptorelin presented to our attention complaining dyspnoea and angina pectoris.

MANAGEMENT AND OUTCOME: Blood examinations revealed normal Troponin I levels. Transthoracic echocardiography revealed no signs of acute myocardial ischaemia. The treadmill stress test revealed S-T tract under levelling in V4-V6 with a very slow resolution. Coronary angiography identified a myocardial bridge in the medium tract of the interventricular anterior artery. Due to these findings, ranolazine and simvastatin were started and, after multidisciplinary assessment, we decided to continue the treatment with enzalutamide. At the first follow-up visit echocardiography found out the cardiological reports stability and no therapy changes were performed. During follow-up visit cardiological revaluation showed reports stability and no therapy changes were performed.

DISCUSSION: Due to the high prevalence of prostate cancer in elderly patients at high cardiovascular risk and the increasing use of androgen receptor-targeted agent, a multidisciplinary approach is highly recommended to weigh survival benefits on toxicities. This case report may support the use of androgen receptor-targeted agent in elderly patients with controlled cardiovascular diseases, a population that is often excluded from randomised trials.

Investigation of cardioprotective effect of lercanidipine on doxorubicin-induced cardiotoxicity

Naunyn Schmiedebergs Arch Pharmacol. 2023 Jun 7. doi: 10.1007/s00210-023-02566-7. Online ahead of print.

ABSTRACT

Although doxorubicin (DOX) is an effective anti-neoplastic drug for many types of cancer, particularly dose-related cardiotoxicity limits the use of the drug. In this study, it was aimed to investigate the protective effect of lercanidipine (LRD) against DOX-induced cardiotoxicity. In our study, 40 Wistar albino female rats were randomly divided into 5 groups as control, DOX, LRD 0.5 (DOX + 0.5 mg/kg LRD), LRD 1 (DOX + 1 mg/kg LRD), and LRD 2 (DOX + 2 mg/kg LRD). At the end of the experiment, the rats were sacrificed, and their blood, heart, and endothelial tissues were examined biochemically, histopathologically, immunohistochemically, and genetically. According to our findings, necrosis, tumor necrosis factor alpha activity, vascular endothelial growth factor activity, and oxidative stress were increased in the heart tissues of the DOX group. In addition, DOX treatment caused the deteriorations in biochemical parameters, and levels of autophagy-related proteins, Atg5, Beclin1, and LC3-I/II were detected. Significant dose-related improvements in these findings were observed with LRD treatment. Besides, Atg5, LC3-I/II, and Beclin1 levels evaluated by western blot revealed that LRD exerts a tissue protective effect by regulating autophagy in endothelial tissue. LRD treatment, which is a new-generation calcium channel blocker, showed antioxidant, anti-inflammatory, and anti-apoptotic properties in heart and endothelial tissue in a dose-dependent manner and also showed protective activity by regulating autophagy in endothelial tissue. With studies evaluating these mechanisms in more detail, the protective effects of LRD will be revealed more clearly.
