The clearance of anthracyclines from the vasculature was studied in perfused tissue-isolated tumors. Human tumor lines MCF-7, U87, and LS174T were implanted in the ovarian fat pad of immune-deficient mice and grown isolated from the surrounding tissue. The initial and continuous tissue uptakes of doxorubicin, daunorubicin, and idarubicin were measured. The clearance of these anthracyclines from...

The clinical use of anthracyclines like doxorubicin and daunorubicin can be viewed as a sort of double-edged sword. On the one hand, anthracyclines play an undisputed key role in the treatment of many neoplastic diseases; on the other hand, chronic administration of anthracyclines induces cardiomyopathy and congestive heart failure usually refractory to common medications. Second-generation ana...

background: nt-probnp is a marker that is released from ventricles in response to pressure and volume overload. raised plasma level of nt-probnp is seen in ventricular dysfunction, ventricular muscular mass reduction or ventricular ischemia. anthracyclines are widely used in treatment of pediatric cancer but their use is associated with cardiotoxicity which increases mortality and morbidity. we...

Introduction: Anthracyclines are one of the classes of chemotherapy drugs that  are widely used to treat many types of cancers including breast cancer. Taking this class of medications has a significant relationship with cardiac dysfunction. N-acetylcysteine has antioxidant properties and may be effective in preventing cardiac dysfunctions. In this study, we investigated the effect of N-acetylc...

Introduction Advances in oncology, such as better access to the health care system, earlier cancer diagnosis, and new chemotherapies, have led longer survival of patients with over last decades. However, this population is vulnerable drug-related adverse cardiovascular events, like cardiomyopathy, which leads heart failure impairs quality life., Among different classes chemotherapeutic agents, ...

Anthracycline therapy is associated with a life-threatening but poorly understood cardiotoxicity. Effects of treatment are consistent with drug-induced disruption of cardiac sarcoplasmic reticulum (SR) calcium homeostasis, including inhibition of calcium release by anthracyclines. This effect, which depends on luminal SR calcium concentration, is hypothesized to involve interactions of anthracy...

In an effort to prevent or reduce anthracycline-induced cardiotoxicity, liposomal anthracyclines have been developed. The objective of this systematic review was to summarise all available evidence on the benefits and risks of liposomal anthracyclines in children with cancer. We searched databases (MEDLINE (1966-September 2009), EMBASE (1980-September 2009) and CENTRAL (The Cochrane Library, is...

Anthracyclines are effective cancer chemotherapeutic agents but can induce serious cardiotoxicity. Understanding the mechanism of cardiac damage by these agents will help in development of better therapeutic strategies against cancer. The GATA-4 transcription factor is an important regulator of cardiac muscle cells. The present study demonstrates that anthracyclines can down-regulate GATA-4 act...

A critical review of the role of anthracyclines in the management of adult patients with acute lymphoblastic leukemia was performed to define current indications for their use. Major pertinent clinical series were reviewed with reference to anthracycline type, cumulative dosage and dose intensity, and administration schedule during both induction therapy and postremission consolidation, compari...
