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...

BACKGROUND: Anthracyclines are one of the most effective chemotherapeutic agents in management of Breast cancer, however Anthracycline induced cardiotoxicity remains a matter of special concern. Detection of early toxicity by use of biomarkers like Troponins has been the focus of interest in recent years. We measured Troponin I levels after chemotherapy with anthracyclines and correlated it with ECG, Echocardiography and clinical findings. METHODS: Patients with early Breast cancer eligible for chemotherapy were included in the study...

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...

REVIEW
Tomoko Negishi, Kazuaki Negishi
Progress in cancer therapy has led to improved prognosis of patients with cancer and thus to a continuous rise of cancer survivors. However, it has simultaneously increased cardiovascular morbidity and mortality rates due to direct and/or indirect side effects of anticancer treatment. Similar to the rapid rise of patients with adult congenital disease, the number of patients suffering or at risk of cardiotoxicity has been steeply increasing and getting an emerging issue. Among the many facets of chemotherapy-induced cardiovascular toxicity, this review attempts to summarize echocardiographic evaluation of cardiac function after cancer chemotherapy by reviewing the definition, risk factors, brief history, limitation of left ventricular ejection fraction and myocardial strain imaging, as well as the limitations of this technique...

PURPOSE: The aim of this study was to assess the left ventricular (LV) remodeling response to chemotherapy in low-cardiac-risk women with newly diagnosed nonmetastatic breast cancer. Cardiotoxic effects of chemotherapy are an increasing concern. To effectively interpret cardiac imaging studies performed for screening purposes in patients undergoing cancer therapy it is necessary to understand the normal changes in structure and function that may occur. METHODS: Twenty women without preexisting cardiovascular disease, of a mean age of 50 years, newly diagnosed with nonmetastatic breast cancer and treated with anthracycline or trastuzumab were prospectively enrolled and evaluated at four time points (at baseline, during chemotherapy, 2 weeks after chemotherapy, and 6 months after chemotherapy) using cardiac magnetic resonance imaging, blood samples, and a clinical questionnaire...

Most photothermal converting systems are not biodegradable, which bring the uneasiness when they are administered into human body due to the uncertainty of their fate. Hereby, we developed a mussel-inspired PLGA/polydopamine core-shell nanoparticle for cancer photothermal and chemotherapy. With the help of an anti-EGFR antibody, the nanoparticle could effectively enter head and neck cancer cells and convert near-infrared light to heat to trigger drug release from PLGA core for chemotherapy as well as ablate tumors by the elevated temperature...

Treatment with Adriamycin (ADR) is one of the major causes of chemotherapy-induced cardiotoxicity and therefore is the principal limiting factor in the effectiveness of chemotherapy for cancer patients. Apigenin (API) has been shown to play a cardioprotective role. The present study examined the effect of API on ADR-induced cardiotoxicity in mice. Sixty male Kunming mice were randomly divided into 4 groups: a control group, ADR model group, low-dose API treatment group (125 mg·kg(-1)), and high-dose API treatment group (250 mg·kg(-1))...

With advances in clinical oncology, the burden of morbidity and mortality for cancer survivors due to the cardiac side effects of the chemotherapy is steadily increasing. Treatment-related cardiac damage is progressive and often irreversible. Primary prevention of cardiotoxicity during treatment is possible with strategies like limiting the cumulative anthracycline dose, the use of anthracycline structural analogs, and especially cardioprotective agents. Areas covered: This review covers the various cardiotoxic chemotherapeutic agents, the pathophysiology of cardiotoxicity due to anthracyclines, and the clinical and subclinical presentations and progression of childhood anthracycline cardiotoxicity...

Cancer was considered an incurable disease for many years; however, with the development of anticancer drugs and state-of-the art technologies, it has become curable. Cardiovascular diseases in patients with cancer or induced by cancer chemotherapy have recently become a great concern. Certain anticancer drugs and molecular targeted therapies cause cardiotoxicity, which limit the widespread implementation of cancer treatment and decrease the quality of life in cancer patients significantly. The anthracycline doxorubicin (DOX) causes cardiotoxicity...

The present translational study aimed to verify whether serial (18)F-fluoro-deoxyglucose Positron Emission Tomography/Computed Tomography (FDG-PET/CT), predicts doxorubicin cardiotoxicity. Methods: Fifteen athymic mice were treated with intravenous administration of saline (n = 5), doxorubicin 5 mg/Kg (n = 5) or doxorubicin 7.5 mg/Kg (n = 5) and submitted to dynamic microPET scan to estimate left ventricular glucose consumption (LV-MRGlu) before and after chemotherapy. Thereafter, we retrospectively identified 69 patients successfully treated with Adriamycin, Bleomycin, Vinblastine, and Dacarbazine (ABVD) regimen for Hodgkin's Disease (HD) and submitted to four consecutive FDG-PET/CT scans...

The long-term usage of doxorubicin (DOX) is largely limited due to the development of severe cardiomyopathy. Many studies indicate that DOX-induced cardiac injury is related to reactive oxygen species generation and ultimate activation of apoptosis. The role of novel mitochondrial fission protein 1 (Mtfp1) in DOX-induced cardiotoxicity remains elusive. Here, we report the pro-mitochondrial fission and pro-apoptotic roles of Mtfp1 in DOX-induced cardiotoxicity. DOX up-regulates the Mtfp1 expression in HL-1 cardiac myocytes...

Cardiotoxicity is an important issue for breast cancer patients receiving anthracycline-trastuzumab therapy in the adjuvant setting. Studies show that 3-36% of patients receiving anthracyclines and/or trastuzumab experience chemotherapy related cardiac dysfunction (CRCD) and approximately 17% of patients must stop chemotherapy due to the consequences of CRCD. There is currently no standardized, clinically verified way to detect CRCD early, but common practices include serial echocardiography and troponin measurements, which can be timely, costly, and not always available in areas where health care resources are scarce...

BACKGROUND: The overexpression of human epidermal growth factor receptor-2 (HER2) in breast cancer is a poor prognosis. Trastuzumab improves overall survival but is associated with cardiotoxicity, especially a decline in left ventricular ejection fraction (LVEF). In addition, chemotherapy and radiotherapy increase fatigue and pain, decrease physical capacity and health-related quality of life. To date, no study has evaluated the benefits of physical activity on the side effects of treatment in patients with HER2 positive breast cancer...

Mehdi Ahmadian, Valiollah Dabidi Roshan
We tested the hypothesis that aerobic exercise training (AET) would modulate doxorubicin-induced cardiotoxicity in rats of various ages. Wistar male rats (n = 72) were assigned to three groups (young, adult, and elderly) with three subgroups for each age: doxorubicin (DG, n = 8), AET + doxorubicin (AETDG, n = 8), AET + Saline (AETSG, n = 8). Following the AET intervention, rats were anesthetized and killed to collect heart tissues in order to determine heat shock protein 70 (HSP70), superoxide dismutase (SOD), malondialdehyde (MDA), interleukin-10 (IL10), and c-reactive protein (CRP)...

BACKGROUND: Trastuzumab (TZB) is an established therapy for HER2-positive breast cancer. The use of TZB is commonly associated with cardiotoxicity manifesting as asymptomatic decrease in left ventricular ejection fraction (LVEF) or overt heart failure. Several studies demonstrated favorable effects of angiotensin-converting enzyme (ACE) inhibitors and β-blockers (BBs) in the prevention of chemotherapy-induced cardiotoxicity. We hypothesize that patients, randomized to receive an ACE inhibitor or a BB during trastuzumab therapy for breast cancer, will maintain a higher LVEF than patients randomized to placebo...
