Because of the paucity of large, randomized trials concerning the cardiac care of patients with cancer, treatment and prevention of chemotherapy-induced cardiotoxicity must rely on insights gained from small trials and case reports as well as the application of guidelines developed for the general population. In these clinical vignettes, we present patients referred by their oncologists to a ca...

Doxorubicin is the mainstay of treatment for various haematological malignancies and solid tumours. However, its clinical application may be hampered by dose-dependent cardiotoxicity. The mechanism of doxorubicin-induced cardiotoxicity may involve various signalling pathways including free radical generation, peroxynitrite formation, calcium overloading, mitochondrial dysfunction and alteration...

The most severe side effect in treated patients with breast cancer is treatment-induced cardiotoxicity, leading to chronic heart failure or CAD, and worsening the patient’s quality of life. The early detection and medical protection is needed to prevent it. The aim of the study was to detect early signs of cardiotoxicity. Material and methods: 148 breast cancer patients were included in the stu...

Aims Breast cancer is the most common cancer among women, and anthracyclines are the most commonly administered drugs for these patients. Cardiotoxicity is one of the complications, which limits the success of this therapy. Very few studies have evaluated anthracycline toxicities within the first few hours after the first infusion, and the majority of published studies were performed in animal ...

In this issue, Gupta et al describe a novel mechanism, mediated through alterations in the RNA-binding protein QKI (Quaking), responsible for anthracycline-mediated cardiotoxicity. Performing global transcriptional profiling in murine hearts exposed to doxorubicin, they identified 5 differentially expressed RNA-binding proteins: 4 of which were upregulated and 1 QKI which was downregulated. QKI...

Objectives: Cardiotoxicity is considered the primary cause of death in aluminum phosphide (ALP)-poisoned cases. Curcumin, the active ingredient of turmeric, is a potent protective polyphenol compound against cardiac diseases including cardiotoxicity. This study aimed to examine the probable cardioprotection potential of nanocurcumin in a rat model of ALP-induced cardiotoxicity. Methods: T...

Despite heightened risk of cardiotoxicity associated with combination therapy of anthracyclines and trastuzumab in HER2-positive breast cancer patients, little research effort has been invested in exploring the molecular mechanisms of cardiotoxicity induced by this combination therapy. In this study, we demonstrate that trastuzumab downregulates both gene and protein expressions of type IIB DNA...
