Arterial hypertension in cancer: The elephant in the room
2019
The great therapeutical success achieved by oncology is counterbalanced by growing evidences of cardiovascular (CV) toxicity due to many antineoplastic treatments. Cardiac adverse events may cause premature discontinuation of effective oncologic treatments or occur as late events undermining the oncologic success. Arterial hypertension is both the most common comorbidity in cancer patients and a frequent adverse effect of anticancer therapies. A pre-existing hypertension is known to increase the risk of other cardiac adverse events due to oncologic treatments, in particular heart failure. Moreover, as a strict association between cancer and CV diseases has emerged over the recent years, var…
Comparative activity of idarubicin and idarubicinol in combination with cyclosporin A in multidrug-resistant leukemia cells
1996
4-Demethoxydaunorubicin (idarubicin, IDA) is an anthracycline that has shown good cytotoxic activity in vitro against tumor cell lines displaying the multidrug-resistant (MDR) phenotype. IDA is converted in the liver into idarubicinol (2HIDA) and, in this form, seems to exert its antitumoral activity in vivo. Recent studies have shown that 2HIDA has tumoricidal activity similar to that of the parent drug when tested in vitro in sensitive neoplastic cells. In this work we compared in vitro the effects of IDA and 2HIDA used alone and in combination with 2 microM cyclosporin A (CyA) in the MDR leukemic cell lines FLCR and K562R and in their sensitive parent cell lines FLC and K562. IDA and 2HI…
Impact of Undernutrition on the Pharmacokinetics and Pharmacodynamics of Anticancer Drugs: A Literature Review
2017
The etiology of undernourishment in cancer patients is multifactorial: tumor-related mechanisms (such as obstruction, metabolic abnormalities, and functionality changes) in addition to the influence of anticancer therapies, which can induce or worsen undernutrition. The evident role of undernutrition in cancer treatment outcomes suggests the need of considering nutritional status when evaluating anticancer drugs. In order to merge the available data and offer researchers and clinicians a global view of this phenomenon, the present manuscript reviews on a drug-by-drug basis the undernutrition-related pharmacokinetic and pharmacodynamic aspects of anticancer treatments. This review notes inte…
Trabectedin-Related Liver Toxicity in Soft Tissue Sarcoma Patients: Always a Good Reason to Discontinue the Treatment?
2014
ABSTRACT Aim: A transient increase in liver enzymes is a well described side effect developed by almost 40% of soft tissue sarcoma (STS) patients treated with trabectedin, often leading to treatment delays or discontinuation. We retrospectively analysed the correlation between trabectedin-related liver toxicity and treatment outcome. Methods: Data from a total of 113 patients receiving trabectedin administered at the dose of 1.5 mg/m2 iv 24 hours in 3 reference centers were evaluated. This exploratory analysis was performed to assess the impact of liver toxicity (grade 3-4 AST and ALT increases) on the trabectedin efficacy and outcome in STS patients. All the patients included had metastati…
0131 : Impact of overweight on anthracycline and trastuzumab-induced cardiotoxicity: experimental study in mice
2015
Trastuzumab (TRZ), a humanized monoclonal antibody against Human Epidermal Growth Factor Receptor 2 (HER2) oncogene, is believed to potentiate doxorubicin (DOX) cardiotoxicity, resulting in left ventricular dysfunction. Few data indicate that overweight could influence DOX-induced cardiotoxicity, and no study has already evaluated the impact of moderate overweight on the cardiotoxic effect of DOX alone or in combination with TRZ. Immediately after birth, litters of C57BL/6 mice were either maintained at 10 (normal litter, NL), or reduced to 3 (small litter, SL) in order to induce programming of ~15% overweight through postnatal overfeeding. At 4 months, in order to evaluate the potentiation…
Iron overload does not potentiate doxorubicin induced cardiotoxicity in vivo in mice and in vitro in cardiomyocytes cell cultures
2013
Background: Doxorubicin (DOX), an anticancer anthracycline, is known to induce serious cardiotoxicity, which is believed to be mediated by oxidative stress and complex interactions with iron. However, the relations between iron metabolism and DOX-induced cardiotoxicity remain a matter of controversy. Methods: Firstly, we used an in vivo murine model of iron overloading (IO) where male C57BL/6 mice received during 3 weeks (D0-D20) a daily dextran-iron injection (15 mg/kg/day.) and then (D21) a single dose of 6 mg/kg DOX. We evaluated cardiac function with echocardiography, myocardial gene's expression, nitro-oxidative stress levels and iron status. Secondly, the anti-proliferative activity o…
Inorganic Nitrate Therapy Improves Doxorubicin-Induced Cardiomyopathy
2011
The anthracycline doxorubicin (DOX) is a potent and effective antineoplastic antibiotic agent widely used in the treatment of a broad range of forms of cancer. The clinical use of DOX is limited by cardiotoxicity, which increases dose dependently and may lead to dilated cardiomyopathy and clinical
Timely recognition of cardiovascular toxicity by anticancer agents: a common objective of the pharmacologist, oncologist and cardiologist.
2011
Both conventional and new anticancer drugs can frequently cause adverse cardiovascular effects, which can span from subclinical abnormalities to serious life-threatening and sometimes fatal events. This review examines the principal basic and clinical elements that may be of profit to identify, prevent and treat such toxicities. Clearly, the accomplishment of such objectives requires the strong commitment and cooperation of different professional figures including, but not limited to, pharmacologists, oncologists and cardiologists. The aspect of anticancer drug cardiotoxicity seems to be somehow underestimated, mainly due to inadequate reporting of adverse reactions from oncology drugs in t…
Soft Tissue Sarcomas (STS)
2021
Soft tissue sarcomas (STSs) represent a rare and heterogeneous group of solid tumors derived from mesenchymal progenitors and account for 1% of all adult malignancies. Although in the last decade anthracycline-based chemotherapy single agent or in combination has been able to improve clinical benefits, prognosis is still poor, and STSs represent an important unmet medical need.
IMPAIRMENT OF DIASTOLIC FUNCTION DURING SHORT-TERM ANTHRACYCLINE CHEMOTHERAPY
1995
International audience; Abstract: Objective-To assess the early changes in left ventricular diastolic and systolic function due to anthracycline treatment. Design-A prospective study of cardiac function by radionuclide angiography in adults before and one month after the end of anthracycline treatment. Patients-60 patients without cardiac disease treated with chemotherapy containing anthracycline. Methods-Cardiac function was assessed by radionuclide measurement throughout treatment. Ejection fraction, peak ejection rate, time to peak ejection rate, filling rate, and time to peak filling rate were measured before and after treatment, To normalise radionuclide measurements of the left ventri…
