Agents that have a damaging effect on the HEART. Such damage can occur from ALKYLATING AGENTS; FREE RADICALS; or metabolites from OXIDATIVE STRESS and in some cases is countered by CARDIOTONIC AGENTS. Induction of LONG QT SYNDROME or TORSADES DE POINTES has been the reason for viewing some drugs as cardiotoxins.

Spherical, heterogeneous aggregates of proliferating, quiescent, and necrotic cells in culture that retain three-dimensional architecture and tissue-specific functions. The ability to form spheroids is a characteristic trait of CULTURED TUMOR CELLS derived from solid TUMORS. Cells from normal tissues can also form spheroids. They represent an in-vitro model for studies of the biology of both normal and malignant cells. (From Bjerkvig, Spheroid Culture in Cancer Research, 1992, p4)

A form of CARDIAC MUSCLE disease, characterized by left and/or right ventricular hypertrophy (HYPERTROPHY, LEFT VENTRICULAR; HYPERTROPHY, RIGHT VENTRICULAR), frequent asymmetrical involvement of the HEART SEPTUM, and normal or reduced left ventricular volume. Risk factors include HYPERTENSION; AORTIC STENOSIS; and gene MUTATION; (FAMILIAL HYPERTROPHIC CARDIOMYOPATHY).
A heterogeneous condition in which the heart is unable to pump out sufficient blood to meet the metabolic need of the body. Heart failure can be caused by structural defects, functional abnormalities (VENTRICULAR DYSFUNCTION), or a sudden overload beyond its capacity. Chronic heart failure is more common than acute heart failure which results from sudden insult to cardiac function, such as MYOCARDIAL INFARCTION.

Novel selective inhibitors for human topoisomerase I, BM2419-1 and -2 derived from saintopin. (1/757)Compounds BM2419-1 and -2 were isolated from a culture broth of a fungus Paecilomyces sp. BM2419. It was shown that these novel compounds were artifacts derived from saintopin, a dual inhibitor of topoisomerase I and II by independent processes. In the human topoisomerase I inhibition assay using the recombinant Saccharomyces cerevisiae, BM2419-1 and -2 inhibited selectively the yeast growth dependent on human topoisomerase I induction with IC50 values of 0.3 ng/ml and 6.0 ng/ml, respectively.

Induction of MDR1 gene expression by anthracycline analogues in a human drug resistant leukaemia cell line. (2/757)The effects of 4-demethoxydaunorubicin (idarubicin, IDA) and MX2, a new morpholino-anthracycline, on up-regulation of the MDR1 gene in the low-level multidrug resistant (MDR) cell line CEM/A7R were compared at similar concentrations (IC10, IC50 and IC90) over a short time exposure (4 and 24 h). The chemosensitivity of each drug was determined by a 3-day cell growth inhibition assay. Compared with epirubicin (EPI), IDA and MX2 were 17- and eightfold more effective in the CEM/A7R line respectively. No cross-resistance to 5-FU was seen in the CEM/A7R line. Verapamil (5 microM) and PSC 833 (1 microM), which dramatically reversed resistance to EPI in the CEM/A7R line, had no sensitizing effect on the resistance of this line to MX2, but slightly decreased resistance to IDA. The sensitivity to 5-FU was unchanged by these modulators. The induction of MDR1 mRNA expression by IDA, MX2 and 5-FU was analysed by Northern blotting and semiquantitatively assessed by scanning Northern blots on a phosphorimager. The relative level of MDR1 expression was expressed as a ratio of MDR1 mRNA to the internal RNA control glyceraldehyde-3-phosphate dehydrogenase (GAPDH). IDA, MX2 and 5-FU differentially up-regulated MDR1 mRNA in the CEM/A7R line in a dose-dependent manner. Both IDA and MX2 induced MDR1 expression within 4 h. 5-FU up-regulated MDR1 expression only when drug exposure was prolonged to 24 h. Based on MRK 16 binding, flow cytometric analysis of P-glycoprotein (Pgp) expression paralleled the increase in MDR1 mRNA levels. For the three anthracyclines, the increase in MDR1 expression was stable in cells grown in the absence of drug for more than 3 weeks after drug treatment. The induction of MDR1 expression by 5-FU was transient, associated with a rapid decrease in the increased Pgp levels which returned to baseline 72 h after the removal of 5-FU. This study demonstrates that MDR1 expression can be induced by analogues of anthracyclines not pumped by Pgp, and that this induction appears to be stable despite a 3-week drug-free period. (+info)
Characterization of aklavinone-11-hydroxylase from Streptomyces purpurascens. (3/757)Aklavinone-11-hydroxylase (RdmE) is a FAD monooxygenase participating in the biosynthesis of daunorubicin, doxorubicin and rhodomycins. The rdmE gene encodes an enzyme of 535 amino acids. The sequence of the Streptomyces purpurascens enzyme is similar to other Streptomyces aromatic polyketide hydroxylases. We overexpressed the gene in Streptomyces lividans and purified aklavinone-11-hydroxylase to apparent homogeneity with four chromatographic steps utilizing a kinetic photometric enzyme assay. The enzyme is active as the monomer with a molecular mass of 60 kDa; it hydroxylates aklavinone and other anthracyclinones. Aklavinone-11-hydroxylase can use both NADH and NADPH as coenzyme but it is slowly inactivated in the presence of NADH. The apparent Km for NADPH is 2 mM and for aklavinone 10 microM. The enzyme is inactivated in the presence of phenylglyoxal and 2,3-butanedione. NADPH protects against inactivation of aklavinone-11-hydroxylase by phenylglyoxal. (+info)
Barminomycin forms GC-specific adducts and virtual interstrand crosslinks with DNA. (4/757)The sequence specificity of the binding of barminomycin (SN-07 chromophore) to DNA was investigated using an in vitro transcription assay. It was found that this compound formed blockages to transcription, and these blocks were highly selective for 5'-GC sequences. The half-lives of the first seven transcriptional blockages at 37 degrees C were 14-130 min, plus one site >>200 min, with widely varying levels of essentially permanent blockages at each site (0-100%; average of 40%), indicative of considerable dependence on flanking sequences of adducts stability at individual GC sites. Barminomycin was also shown to form DNA virtual (i.e. functional) interstrand crosslinks. Such crosslinks were also relatively heat stable, with 40% of the DNA remaining crosslinked after heating at 90 degrees C for 5 min. The barminomycin-DNA adducts and crosslinks appear to be essentially identical to those formed between adriamycin and DNA. Whereas adriamycin requires prior activation with formaldehyde in order to form adducts and crosslinks, barminomycin behaves in all respects as if it is a pre-activated form of adriamycin. (+info)
Development of a self-cloning system for Actinomadura verrucosospora and identification of polyketide synthase genes essential for production of the angucyclic antibiotic pradimicin. (5/757)A self-cloning system for Actinomadura verrucosospora, a producer of the angucyclic antibiotic pradimicin A (PRM A), has been developed. The system is based on reproducible and reliable protoplasting and regeneration conditions for A. verrucosospora and a novel plasmid vector that consists of a replicon from a newly found Actinomadura plasmid and a selectable marker cloned from the Actinomadura strain. The system has an efficiency of more than 10(5) CFU/microgram of DNA. Using this system, we have cloned and identified the polyketide synthase (PKS) genes essential for PRM A biosynthesis from A. verrucosospora. Nucleotide sequence analysis of the 3.5-kb SalI-SphI fragment showed that ketosynthase subunits (open reading frame 1 [ORF1] and ORF2) of the essential PKS genes have strong similarities (59 to 89%) to those for angucyclic antibiotic biosynthesis.

Altered multidrug resistance phenotype caused by anthracycline analogues and cytosine arabinoside in myeloid leukemia. (6/757)The expression of P-glycoprotein (Pgp) is often increased in acute myeloid leukemia (AML). However, little is known of the regulation of Pgp expression by cytotoxics in AML. We examined whether Pgp expression and function in leukemic blasts was altered after a short exposure to cytotoxics. Blasts were isolated from 19 patients with AML (15 patients) or chronic myeloid leukemia in blastic transformation (BT-CML, 4 patients). Pgp expression and function were analyzed by flow cytometric analysis of MRK 16 binding and Rhodamine 123 retention, respectively. At equitoxic concentrations, ex vivo exposure for 16 hours to the anthracyclines epirubicin (EPI), daunomycin (DAU), idarubicin (IDA), or MX2 or the nucleoside analogue cytosine arabinoside (AraC) differentially upregulated MDR1/Pgp expression in Pgp-negative and Pgp-positive blast cells. In Pgp-negative blasts, all four anthracyclines and AraC significantly increased Pgp expression (P =.01) and Pgp function (P =.03). In contrast, MX2, DAU, and AraC were the most potent in inducing Pgp expression and function in Pgp positive blasts (P <.05). A good correlation between increased Pgp expression and function was observed in Pgp-negative (r =.90, P =.0001) and Pgp-positive blasts (r =.77, P =.0002). This increase in Pgp expression and function was inhibited by the addition of 1 micromol/L PSC 833 to blast cells at the time of their exposure to these cytotoxics. In 1 patient with AML, an increase in Pgp levels was observed in vivo at 4 and 16 hours after the administration of standard chemotherapy with DAU/AraC. Upregulation of Pgp expression was also demonstrated ex vivo in blasts harvested from this patient before the commencement of treatment. In 3 other cases (1 patient with AML and 2 with BT-CML) in which blasts were Pgp negative at the time of initial clinical presentation, serial samples at 1 to 5 months after chemotherapy showed the presence of Pgp-positive blasts. All 3 patients had refractory disease. Interestingly, in all 3 cases, upregulation of Pgp by cytotoxics was demonstrated ex vivo in blasts harvested at the time of presentation. These data suggest that upregulation of the MDR1 gene may represent a normal response of leukemic cells to cytotoxic stress and may contribute to clinical drug resistance. (+info)
Correlation between the kinetics of anthracycline uptake and the resistance factor in cancer cells expressing the multidrug resistance protein or the P-glycoprotein. (7/757)Multidrug resistance (MDR) in model systems is known to be conferred by two different integral proteins, the 170-kDa P-glycoprotein (Pgp) and the 190-kDa multidrug resistance-associated protein (MRP1). One possible pharmacological approach to overcome drug resistance is the use of specific inhibitors, which enhance the cytotoxicity of known antineoplastic agents. However, while many compounds have been proven to be very efficient in inhibiting Pgp activity only some of them are able to inhibit MRP1. The other likely approach is based on the design and synthesis of new non-cross-resistant drugs with physicochemical properties favoring the uptake of the drug by the resistant cells. The intracellular drug retention influences its cytotoxic effect. The level of the intracellular drug content is a function of the amount of drug transported inside the cell (influx) and the amount of drug expelled from the cell (efflux). In this work, the kinetics of drug uptake and the kinetics of active efflux of several anthracycline derivatives in both Pgp expressing K562/Adr cells and MRP1 expressing GLC4/Adr cells was determined. Our data have shown that in both cell lines there is no correlation between the resistance factor and the kinetics of drug efflux by these pumping systems. However, a very good correlation between the resistance factor and the kinetics of drug uptake has been established in both cell lines: the resistance factor decreases when the kinetics of drug uptake increases. This work has clearly shown that when the rate of transmembrane transport of anthracycline is high enough, the efflux mediated by the protein transporter is not able to pace with it. The protein transporter essentially operates in a futile cycle and the resistance factor is tending to one. It does not mean, however, that when the resistance factor is close to one the anthracycline is not transported by the pump. (+info)
Localization of a substrate specificity domain in the multidrug resistance protein. (8/757)Multidrug resistance protein (MRP) confers resistance to a number of natural product chemotherapeutic agents. It is also a high affinity transporter of some physiological conjugated organic anions such as cysteinyl leukotriene C(4) and the cholestatic estrogen, 17beta-estradiol 17(beta-D-glucuronide) (E(2)17betaG). We have shown that the murine orthologue of MRP (mrp), unlike the human protein, does not confer resistance to common anthracyclines and is a relatively poor transporter of E(2)17betaG. We have taken advantage of these functional differences to identify region(s) of MRP involved in mediating anthracycline resistance and E(2)17betaG transport by generating mrp/MRP hybrid proteins. All hybrid proteins conferred resistance to the Vinca alkaloid, vincristine, when transfected into human embryonic kidney cells. However, only those in which the COOH-terminal third of mrp had been replaced with the corresponding region of MRP-conferred resistance to the anthracyclines, doxorubicin, and epirubicin. Exchange of smaller segments of the COOH-terminal third of the mouse protein by replacement of either amino acids 959-1187 or 1188-1531 with those of MRP produced proteins capable of conferring some level of resistance to the anthracyclines tested. All hybrid proteins transported cysteinyl leukotriene C(4) with similar efficiencies. In contrast, only those containing the COOH-terminal third of MRP transported E(2)17betaG with an efficiency comparable with that of the intact human protein. The results demonstrate that differences in primary structure of the highly conserved COOH-terminal third of mrp and MRP are important determinants of the inability of the murine protein to confer anthracycline resistance and its relatively poor ability to transport E(2)17betaG.

Genetic polymorphisms of MTHFR and GSTP1 is associated with chemotherapy related toxicity in breast cancer patients | ...
Genetic polymorphisms in drug-metabolizing enzymes have been linked to inter-individual differences in the efficacy and toxicity of many medications. The aim of our study was to reveal the association of MTHFR and GSTP1 gene polymorphisms with toxicity in breast cancer patients treated with adjuvant anthracycline-based treatment. The case group comprised 74 patients with breast cancer (median age: 48.9, range: 2769 years; stage: II-III). All patients received 6 cycles of adjuvant anthracycline-based chemotherapy regimen with 5-fluorouracil, adriamycin, and cyclophosphamide (FAC). Toxicity was assessed using NCI-CTC. The polymorphic variants of the MTHFR (c. 677 C>T) and GSTP1 (c. 313 A>G) were analyzed by Allelic Discrimination Real Time PCR using specific primers and TaqMan MGB probes. The genotypes distributions observed were similar to Hardy-Weinberg equilibrium expectations. The association between genotypes and toxicity was tested using univariate logistic regression and logistic regression ...
Early detection of anthracycline-induced cardiotoxicity using two-dimensional speckle tracking echocardiography | Kang |...
Figure 4. Bland-Altman analysis for intra-observer and inter-observer reliability.. Discussion. Anthracyclines, such as doxorubicin and epirubicin, have been used extensively and continue to be some of the most active cytotoxic agents available to treat a wide spectrum of hematologic malignancies and solid tumors, including acute myeloid, lymphoid leukemia, lymphoma and breast cancer. As a result of advances in the treatment of cancers, the number of survivors will fortunately continue to increase.. Unfortunately, despite their success in treating cancer, anthracyclines are limited by their serious toxic effects on the myocardium. Life altering cardiac sequelae from anthracyclines remain a problem, with a range of 5-23% of patients developing late-onset heart failure secondary to anthracycline-induced cardiotoxicity . Reliable, sensitive and non-invasive method in detecting cardiac function is of vital importance during anthracycline administration.. Strain is a dimensionless parameter ...

Trabectedin in Patients with Advanced Soft-Tissue Sarcoma (STS) Who Are Unfit for Standard Chemotherapy | Oncology Practice...
The activity and tolerability of trabectedin has been widely studied in the second-line STS setting, but few studies evaluate it as first-line therapy for patients with comorbidities that preclude anthracycline-based chemotherapy. This study, TR1US, assessed the efficacy, tolerability, and pharmacokinetics of trabectedin in patients with STS in the latter group.. In this study, patients received trabectedin 1.3 to 1.5 mg/m2 as a 24-hour infusion every 3 weeks until progression or unacceptable toxicity. Response, progression-free survival (PFS), and overall survival (OS) were assessed per RECIST 1.1 and Kaplan-Meier, respectively. From February 2014 to December 2015, 24 patients were enrolled. Their median age was 78 years (range, 64-89 years). STS histologies were leiomyosarcoma (46%), liposarcoma (33%), and others (21%). Two patients had previously received adjuvant anthracycline-based chemotherapy. A median of 4 cycles of trabectedin were delivered.. Among the 24 patients, 2 achieved partial ...

Drugs to prevent heart damage in cancer patients receiving anthracyclines | Cochrane
Anthracyclines are among the most effective chemotherapy treatments available for various types of cancer. However, there is a risk of damage to the heart (cardiotoxicity) depending on the cumulative dose. Certain drugs might prevent this damage, but for many of these drugs, the review authors found no high quality evidence about whether they were effective in protecting the heart and they were unable to draw conclusions. For dexrazoxane, the review authors found 10 studies enrolling over 1600 patients. These studies provided evidence that dexrazoxane prevented heart damage without interfering with the anti-tumour effects of anthracycline treatment. Patients who got dexrazoxane with their anthracycline treatment had about one third of the risk of heart failure compared to patients who got anthracyclines without dexrazoxane. Dexrazoxane had no effect on survival. We cant be sure about whether it had any undesirable side effects.. ...

Anthracycline-based chemotherapy is widely used as adjuvant treatment for breast cancer. In addition to the challenge posed by anthracycline-induced cardiotoxicity, there are issues surrounding previous treatment with anthracyclines which limit its utility in the metastatic disease setting. Many patients with advanced disease will have had prior anthracycline-based adjuvant therapy, may have reached a maximum cumulative lifetime dose, or developed refractory disease, creating an obvious need for non-anthracycline treatment strategies.3 Platinum- and taxane-based chemotherapies as first-line therapy for metastatic breast cancer have demonstrated significant activity, producing single-agent response rates , 50%; in combination these rates increased to , 60% in both previously untreated and in patients who previously received anthracyclines.3 However, overall survival has remained relatively unchanged.4 As there is currently no standard of care for patients with metastatic breast cancer, various ...

Prospective longitudinal assessment of late anthracycline cardiotoxicity after childhood cancer: the role of diastolic function...
Alterations in Doppler derived diastolic filling characteristics in anthracycline treated children have been reported previously. Some have described frequent abnormalities,5 with numerically small changes, directionally variable and not confined to those receiving anthracyclines. Others have not been able to detect any differences from controls,2 neither at rest nor during dobutamine stress testing. All but one of these studies of diastolic function in anthracycline treated children has included a variety of different diagnostic groups receiving various anthracycline schedules. Rammeloo and colleagues2 studied children with ALL only, but found no indices of diastolic dysfunction. However, anthracycline doses were low (100 mg/mg2).. Restrictive LV filling has been proposed as a consequence of chronic progressive myocardial anthracycline induced damage, but our observations in patients treated with moderate anthracycline doses and a follow up interval of 10-11 years, would question this ...
Perceived resource constraints within the Canadian health care system might threaten adoption of pharmacogenomic testing. We therefore propose prioritizing serious ADRs where delays in access to tests put patients at risk of devastating consequences that also represent substantial cost burdens on the health care system. Pharmacogenomic testing for serious ADRs also holds the most promise for cost effectiveness. We have shown that cost savings associated with the prevention of one such ADR, anthracycline-induced cardiotoxicity, are predicted to outweigh the costs of testing.20 Specifically, severe cases of anthracycline-induced cardiotoxicity cost more than $1 million owing to the need for heart transplants,20 and incorporation of pharmacogenomic testing is estimated to save $495 per patient, representing a 5.7% reduction in costs associated with anthracycline-based cancer treatment.20. Several parameters must be optimized to improve access for our proposed approach to pharmacogenomic testing, ...
Letter by Patanè Regarding Article, Early Detection of Anthracycline Cardiotoxicity and Improvement With Heart Failure Therapy...
I have read the article by Cardinale and colleagues1 with great interest and congratulate the authors for the completion of a burdensome work and the excellent presentation of their results. As the authors have correctly stated, early preclinical cardiac injury should be looked for soon after anthracycline treatment to effectively treat this disorder from its onset, before its overt clinical expression. However, I would like to point out one aspect that needs further clarification. The authors have reported that the overall incidence of cardiotoxicity is 9%. Previous researches have reported that anthracycline promotes cancer cell death via regulator of G-protein signaling 6 (RGS6)-mediated activation of ataxia telangiectasia-mutated serine/threonine protein kinase and the resultant upregulation of tumor suppressor p53, leading to an apoptosis pathway underlying its cytotoxic activity. The ability of RGS6 to promote p53 activation in response to anthracycline is independent of RGS6 interaction ...

Neurohormonal Blockade and Circulating Cardiovascular Biomarkers During Anthracycline Therapy in Breast Cancer Patients:...
Different classes of cardiovascular biomarkers are thought to provide information concerning different pathophysiological mechanisms.16 Because anthracycline therapy is associated with both cardiomyocyte injury, loss of cardiac contractile function, inflammation, and development of diffuse fibrosis,17 we selected biomarkers that are believed to reflect these processes in our study.. Cardiac troponins are markers of cardiomyocyte injury and are associated with risk for cardiovascular death and heart failure.18 Moreover, the use of high‐sensitivity assays for cTnI and cTnT also permits detection and monitoring of low‐grade, chronic myocardial injury.19 BNP and NT‐proBNP are associated with cardiac function and provide strong prognostic information across the spectrum of cardiovascular disease.20, 21, 22 CRP is a prototypical inflammatory biomarker that has been associated with the incidence of cardiovascular disease and death, both in the general population, in patients with coronary artery ...
Abstract 17537: Pathologic Atrophy of the Left Ventricular Myocardium Early After Receipt of Anthracycline-Based Chemotherapy |...
Background: Aortic stiffening produces systolic hypertension and increases left ventricular (LV) wall stress. Normally this stimulates LV hypertrophy to normalize wall stresses. Previously, we have shown aortic stiffness abruptly increases within 3 to 6 months of anthracycline-based chemotherapy (Anth-bC) initiation, but the effect of this increase on LV mass and remodeling is unknown.. Methods: We performed cardiac magnetic resonance (CMR) on 73 individuals (49 receiving Anth-bC [67% women; 49±14 years] and 24 healthy volunteers [58% women; 52±8 years]) at baseline and 6 months after Anth-bC initiation. In blinded analyses we measured aortic arch stiffness (pulse wave velocity [PWV]) and LV volumes, shape (sphericity index), mass, and wall stress. Paired and two sample t tests were performed to assess differences in cohorts and serial CMR measures. We fit multivariate models to each cohort to examine associations of change in CMR measurements after adjustment for covariates.. Results: In ...

Dual HER2 blockade: preclinical and clinical data | Breast Cancer Research | Full Text
In the metastatic setting, a phase III clinical trial comparing lapatinib versus lapatinib and trastuzumab in 296 patients who had progressed on a trastuzumab-containing regimen demonstrated an improvement in progression-free survival (hazard ratio (HR), 0.73; 95% confidence interval, 0.57 to 0.93; P = 0.08) and a trend towards improved OS (HR, 0.75; 95% confidence interval, 0.53 to 1.07; P = 0.106) in patients receiving the combination . This observation provided further evidence for combined HER2 blockade as well as continued use of trastuzumab beyond disease progression.. Six randomized neoadjuvant trials and one nonrandomized neoadjuvant trial as well as one adjuvant trial have evaluated the role of dual targeted therapies with lapatinib and trastuzumab (Table 2). Two large studies were conducted with a taxane-only backbone with anthracycline chemotherapy given after surgery. In the phase III study of NeoALTTO, 455 patients received paclitaxel with lapatinib, trastuzumab or the ...
Risk of Heart Failure Greater in Patients With AML, ALL on Anthracyclines | AJMC
In cases of acute myeloid leukemia (AML) or acute lymphoblastic leukemia (ALL), there is a greater risk of symptomatic heart failure in the first year following initiation of anthracycline treatment.
This study was designed to monitor 18F-FMISO-PET during a WoO with nintedanib, a novel TKI with interesting results to date, and to determine whether 18F-FMISO PET would show predictive/prognostic capacity or shed light on the mechanisms of resistance to nintedanib. The randomized design was adopted to distinguish predictive from prognostic properties of the biomarker. To avoid confusion in the biomarker interpretation, most of the standard chemotherapy that is usually administered in this setting (a taxane plus an anthracycline-based regimen) was removed from the trial schedule; the anthracycline-based regimen was administered after trial completion in the post-operative setting. Thus, despite the randomized design, the trial was not powered to compare the RCB rate between treatment arms or determine the true efficacy of nintedanib plus standard neoadjuvant chemotherapy. In any case, doubling the rate of pCR (RCB-0 and -I) in the hormone-positive population, which constituted the 79% of the ...

Preparation of Anthracyclines Liposomes for Tumor-Targeting Drug Delivery | Springer for Research & Development
Anthracyclines are the most effective anticancer drugs with broad cancer spectrum. They demonstrate strong anticancer efficacy in vitro but are less effective in vivo during treatment of brain cancer...
One major barrier to the eradication of DLBCL with anthracycline-based chemotherapy is the ability of certain lymphomas to exhibit resistance to these drugs. Anthracycline resistance may be intrinsic or acquired and may occur through multiple mechanisms. These mechanisms may be classified in two major groups: (i) decreased drug accumulation and/or increased drug inactivation, for example, via upregulation of the MDR/TAP (multidrug resistance/antigen peptide transporter) genes; this mechanism has been characterized in cell and animal models but its relevance to clinical resistance remains unclear in most tumor types (46-49) and (ii) biologic mechanisms that prevent cell death from occurring after anthracycline-induced damage. Accumulating evidence indicates that the capacity of most cancers to resist the cytotoxic effects of chemotherapy is more closely connected to genetic and epigenetic abnormalities that affect critical cell-cycle checkpoint and cell death pathways than to specific mechanisms ...

Side Effect - Cardiac
Anthracyclines (such as doxorubicin) are very important (effective) agents for the treatment of lymphomas, however the use of anthracyclines increases the risk of damage to the heart (cardio toxicity. The risk of cardio toxicity is greater for the elderly and pediatric patients, and in persons with preexisting heart issues. The risk is also related to the cumulative dose of the anthracycline drug, and possibly the rate of administration - how fast it is given.. ...
October | 2013 | Thrombin Inhibitors | Page 2
We demonstrated that a minimal dose of Dox combined that has a suboptimal dose of WFA was really efficient in suppressing tumor progression by lowering proliferation and angiogenesis while improving autophagy, DNA injury, and apoptosis , indicating that combining WFA with Dox reduces the dosage requirement of Dox to suppress tumor development, and hence could lessen or eliminate the negative effects which includes myocardial toxicity linked with substantial doses of Dox applied to deal with various strong cancers including ovarian cancer. Anthracyclines are amid quite possibly the most useful anticancer solutions ever formulated, but their clinical use is restricted by their cumulative dose-related cardiotoxicity which may possibly eventually lead to a severe type of cardiomyopathy . Regardless of reliable proof proving the induction of apoptosis in cardiomyocytes exposed to doxorubicin in vitro, there may be controversy above whether or not apoptosis contributes to doxorubicin-induced ...

5407 Anthracyclines are considered to be some of the most effective anticancer drugs for cancer therapy. However, drug resistance and cardiotoxicity of anthracyclines limit their clinical application. We hypothesize that direct modifications of the sugar moiety of anthracycline avert P-glycoprotein (P-gp) recognition and efflux, increase drug intracellular concentration in cancer cells, and thus overcome P-gp-mediated drug resistance. Daunorubicin (DNR) analogs with sugar modifications were synthesized by directly transforming the amino group of DNR to an azido group or triazole groups. Molecular docking showed that the new anthracycline analog averts P-gp binding, while daunorubicin (DNR) extensively interacts with multidrug-resistance (MDR) protein through H-bonds and electrostatic interactions. FACS assay demonstrated that these new compounds abolished P-gp drug efflux and accumulated high intracellular concentration in the drug-resistant leukemia K562/Dox. P-gp inhibition by CsA confirmed ...

The International Myeloma Foundation Nurse Leadership Board (NLB) used Melnyk and Fineout-Overholts (2011) levels of evidence as a systematic framework for the appraisal and grading of the NLBs consensus statements and evidence-based recommendations. • Nurses should teach patients with MM about their increased risk for DVT, measures they can take to prevent DVT (ambulation to prevent venous stasis and avoidance of dehydration), the signs and symptoms of DVT (such as edema and pain in the extremity), and the need to report any DVT symptoms immediately (Lyman et al., 2015; Rome, Doss, Miller, & Westphal, 2008). • Nurses and clinicians should use risk stratification to determine patients risks of developing VTE. Factors that increase VTE risk include a history of prior VTE, surgery, anthracycline chemotherapy, high-dose corticosteroids, hospitalization, and heart disease. All high-risk patients who take IMiDs should also take aspirin, LMWH, warfarin, or fondaparinux prophylaxis. Preventive ...

Doxorubicin QuickView - Correlation Engine
Doxorubicin is an antineoplastic in the anthracycline class. General properties of drugs in this class include: interaction with DNA in a variety of different ways including intercalation (squeezing between the base pairs), DNA strand breakage and inhibition with the enzyme topoisomerase II. Most of these compounds have been isolated from natural sources and antibiotics. However, they lack the specificity of the antimicrobial antibiotics and thus produce significant toxicity. The anthracyclines are among the most important antitumor drugs available. Doxorubicin is widely used for the treatment of several solid tumors while daunorubicin and idarubicin are used exclusively for the treatment of leukemia. Doxorubicin may also inhibit polymerase activity, affect regulation of gene expression, and produce free radical damage to DNA. Doxorubicin possesses an antitumor effect against a wide spectrum of tumors, either grafted or spontaneous. The anthracyclines are cell cycle-nonspecific ...

Pretreatment Hemoglobin Adds Prognostic Information To The NCCN-IPI In Patients With Diffuse Large B-Cell Lymphoma Treated With Anthracycline-Containing Chemotherapy
Decreases in left ventricular ejection fraction (LVEF) have been reported with HER2 inhibitors, including pertuzumab; however, the rate of cardiotoxicity has not been increased compared with placebo in studies of pertuzumab/trastuzumab/ docetaxel. Patients who received prior anthracycline therapy or chest irradiation may be at an increased risk for cardiotoxicity, and LVEF should be evaluated prior to initiation of pertuzumab as well as at regular intervals during treatment (eg, every 3 months). Pertuzumab and trastuzumab treatment should be withheld for at least 3 weeks for a drop in LVEF to less than 40% or LVEF of 40% to 45% with a 10% or greater absolute decrease below pretreatment values. Pertuzumab may be resumed if the LVEF has recovered to greater than 45% or to 40% to 45% associated with less than a 10% absolute decrease below pretreatment values.1,2 ...
Patients and methods: Prospective study of 57 pts treated at the Institut Curie between 02/2004 and 01/2007 by concurrent T-RT for non-metastatic BC. The perfusion of trastuzumab started either with or after chemotherapy (CT). RT, started at least 4 weeks after the completion of anthracycline-based chemotherapy, consisted of either whole breast (+/- boost) or chest wall normo-fractionated irradiation. When indicated the internal mammary chain (IMC) and supra/infra-clavicular lymph nodes were also irradiated. Left ventricular ejection fractions (LEVF), assessed at baseline, before start of RT (pre-RT), after completion of RT and then every 4-6 months with either echocardiography or multiple gated acquisition scanning, were considered normal if ≥50% or stated so by the cardiologist. A normal LVEF at baseline was one of the inclusion criteria. Skin toxicity was evaluated using CTCAEV3 ...
ASH International Clinical Collaboration Replicates High Cure Rate of APL in Developing Countries | SYS-CON GERMANY
WASHINGTON, Jan. 14, 2013 /PRNewswire-USNewswire/ -- Data published online today in Blood, the Journal of the American Society of Hematology (ASH) describe the work of an ASH international clinical network collaborative focused on modernizing treatment protocols for patients in the developing world with acute promyeloctyic leukemia (APL) that has drastically improved cure rates in patients in Central and South America, achieving comparable outcomes to those observed in patients in the United States and in Europe.. APL is a rare, aggressive cancer of the blood and bone marrow that can be fatal in a matter of hours or days without prompt diagnosis and treatment. Thanks to the introduction of combination therapy with all-trans retinoic acid (ATRA) and anthracycline-based chemotherapy, APL has become a highly curable disease for patients in most developed countries. Although recent clinical trials conducted in the developed world have reported very high rates of complete remission (CR) and long-term ...
