In Europe, mitral regurgitation (MR) is the second most common form of valvular heart disease requiring surgical treatment. The case is presented of a 36-year-old woman with end-stage heart failure secondary to chemotherapy-induced cardiotoxicity, complicated by severe MR. She was listed for heart transplantation and underwent percutaneous MitraClip® implantation in order to preclude further clinical deterioration while awaiting a suitable donor. The one-year follow-up showed a strong improvement of symptoms and mostly reverse left ventricular remodelling, with consequent removal from the heart transplantation list...

In order to realize a combination of chemotherapy and selective drug release into tumor cells, novel pH-sensitive prodrugnanoparticles were designed and prepared via the self-assembly of a synthetic amphiphilic macromolecular prodrug for the selective co-delivery of doxorubicin (Dox) and curcumin (Cur). Dox was covalently conjugated to the oxidized sodium alginate through a Schiff base reaction to produce an amphiphilic macromolecular prodrug, and the prodrug was subsequently self-assembled into nanoparticles (Dox-NPs) in an aqueous solution, which were responsive to the acidic environment in tumor cells...

Doxorubicin (Dox) is an anthracycline antibiotic widely used in cancer treatment. Although its antitumor efficacy appears to be dose dependent, its clinical use is greatly restricted by development of cardiotoxicity. Sirtuin-3 (Sirt3) is the major deacetylase within the mitochondrial matrix that plays an important role in regulation of cardiac function. This study was performed to identify the regulatory role of Sirt3 on Dox-induced cardiac hypertrophy and mitochondrial dysfunction in rats in vivo and in vitro...

As the overall survival of patients with lung cancer continues to increase, more cancer survivors are faced with the risk of developing treatment-related cardiovascular toxicities. The increased knowledge of the molecular biology of non-small cell lung cancer has led to new and more personalized treatments. Nevertheless, the usual chemotherapy schemes and radiation therapy induce cardiac toxicities that are frequently underappreciated or go unnoticed. Up to date, the majority of cardiotoxicity studies have been focused in breast cancer, but new treatments in lung cancer patients, such as immune checkpoint-blocking antibodies or tyrosine kinase inhibitors, may also exert these cardiac toxic effects and therefore demand of the close collaboration of oncologists and cardiologists, in order to be addressed...

OBJECTIVES: The major clinical side effect of the ERBB2-targeted breast cancer therapy, trastuzumab, is a decline in the left ventricular ejection fraction (LVEF). Improved markers are needed to better identify patients susceptible to cardiotoxicity. METHODS: The NCCTG N9831 trial compared adjuvant doxorubicin and cyclophosphamide followed by either weekly paclitaxel (arm A); paclitaxel then trastuzumab (arm B); or concurrent paclitaxel and trastuzumab (arm C) in patients with HER2-positive breast cancer...

In the United States, the lifetime risk of a cancer diagnosis is nearly 40%; in 2016, that represents almost 1.6 million new patients, and despite advances in early diagnosis and treatment, roughly 35% will ultimately die of their malignancy. Fortunately, the number of patients living with a cancer diagnosis also continues to expand, anticipated to be more than 19 million in less than a decade. In calculating the relative risks and benefits of therapy, it is therefore important to consider the morbidity and mortality associated with antitumor therapy itself...

Despite the known cardiotoxic effects of doxorubicin and other anthracyclines, no evidence-based guidelines exist for the surveillance and prevention of chemotherapy-induced cardiotoxicity in adult survivors of breast cancer who have had limited previous doses of anthracyclines (ie, total cumulative dose 240 mg/m(2)), or limited-dose anthracyclines followed by trastuzumab-based regimens. Nonetheless, some national and international cardio-oncology and cardiac-imaging organisations recommend increased cardiac surveillance during or after treatment, measurement of cardiac biomarkers and other surrogate endpoints, and in some cases initiation of cardioprotective drug therapy in asymptomatic women...

BACKGROUND/AIM: Bevacizumab combined with standard chemotherapeutics has become a choice of treatment for several kinds of cancers. Hypertension, third-degree albuminuria, thrombosis and cardiotoxicity are the reported side-effects of bevacizumab. Among them, cardiotoxicity is a most severe, but rare outcome. We report a case of a 62-year-old female with colorectal carcinoma who was given bevacizumab-containing chemotherapy for more than 20 months and achieved a stable disease during the entire course of treatment...

Biological therapy comprises agents that by virtue of their unique mechanisms of action, are able to specifically incite a response against or target malignant cells. They differ from conventional chemotherapy with regard to mechanisms of action, indications and side effect profile. Biologic agents have revolutionized therapy for a number of malignancies. In the setting of gastrointestinal (GI) malignancies, agents targeting vascular endothelial growth factor (VEGF), human epidermal growth factor receptor 2 (Her2/Neu) and epidermal growth factor receptor (EGFR) have proven to be invaluable additions to chemotherapy...

Doxorubicin (DOX) induced cardiotoxicity is a major problem during chemotherapy of cancers. DOX-mediated suppression of type 1 IGF receptor (IGF-1R) signaling leads to cardiac dysfunction. Neferine, a bisbezylisoquinoline alkaloid from the seed embryos of Nelumbo nucifera Gaertn possesses a distinct range of pharmacological properties. Herewith, the present study attempts to elucidate the protective role of neferine against DOX induced toxicity in H9c2 rat cardiomyoblast cell line model. DOX-treated H9c2 cells significantly increased mitochondrial superoxide generation, depleted cellular antioxidant status, suppressed the activation of IGF-1R signaling via PI3K/Akt/mTOR and induced autophagy by the activation of ULK1, Beclin1, Atg7 and LC3B...

The very effective anticancer drug doxorubicin (DOX) is known to have cardiotoxic side effects, which could be accompanied by autonomic modulation. Autonomic disbalance might even be an initiating mechanism underlying DOX-induced cardiotoxicity and can be studied noninvasively by the analysis of heart rate variability (HRV). A number of strategies have been assessed to predict chemotherapy-induced cardiac dysfunction while HRV, a potential detecting tool, has not yet been tested. Thus, we aimed to determine the effect of DOX treatment on HRV in a rat model of colorectal cancer...

An increased risk of arteriosclerosis has been noted in cancer survivors. Currently, there are only a few reports available that consider the risk of arteriosclerosis in patients treated with chemotherapy. Patients with an advanced stage B-cell malignant lymphoma are typically treated with a combination therapy of rituximab and cyclophosphamide, doxorubicin, vincristine, and prednisolone (R-CHOP). Complications such as diabetes mellitus (DM), hyperlipidemia (HL), and osteoporosis due to prednisolone and cardiotoxicity due to anthracyclines are well known...

Increase in oxidative/nitrosative stress is one of the mechanisms associated with the development of cardiotoxicity due to Doxorubicin (Dox), a potent chemotherapy drug. Previously, we reported mitigation of Dox-induced oxidative/nitrosative stress and apoptosis by Vitamin C (Vit C) in isolated cardiomyocytes. In the present in vivo study in rats, we investigated the effect of prophylactic treatment with Vit C on Dox-induced apoptosis, inflammation, oxidative/nitrosative stress, cardiac dysfunction and Vit C transporter proteins...

The primary aim of this study was to find the potential modulatory roles of quercetin (QUE) against Adriamycin (ADR)-induced cardiotoxicity. A total of 50 rats were assigned to five groups: a control group, an ADR-treated group, a QUE-treated group, a prophylaxis-cotreated group, and a therapeutic-cotreated group, respectively. QUE exhibited a significant cardioprotective effect, particularly, when it was administered prior to and concurrently with ADR treatment (prophylaxis-cotreated group). This effect was biochemically evident by the significant decreases in the serum levels of myocardial injury biomarkers such as troponin, creatine kinase-myocardium bound, and creatine phosphokinase...

Trastuzumab-induced cardiotoxicity (TIC) is the primary adverse event that limits the use of trastuzumab in HER2-positive breast cancer patients. However, the incidence and risk factors of TIC in HER2-positive gastric cancer are not known. Therefore, we evaluated the incidence and predictive factors of TIC in gastric cancer patients treated with trastuzumab in clinical practice. We reviewed cardiac dysfunction in HER2-positive gastric cancer patients between December 2005 and April 2015 in a prospectively-collected database that included prospective clinical trials at Yonsei Cancer Center, Republic of Korea...
