The lipid lowering drug lovastatin protects against doxorubicin-induced hepatotoxicity.
2012
Liver is the main detoxifying organ and therefore the target of high concentrations of genotoxic compounds, such as environmental carcinogens and anticancer drugs. Here, we investigated the usefulness of lovastatin, which is nowadays widely used for lipid lowering purpose, as a hepatoprotective drug following the administration of the anthracycline derivative doxorubicin in vivo. To this end, BALB/c mice were exposed to either a single high dose or three consecutive low doses of doxorubicin. Acute and subacute hepatotoxicities were analyzed with or without lovastatin co-treatment. Lovastatin protected the liver against doxorubicin-induced acute pro-inflammatory and pro-fibrotic stress respo…
Acute Administration of Epirubicin Induces Myocardial Depression in Isolated Rat Heart and Production of Radical Species Evaluated by Electron Spin R…
2007
The aim of our study was to evaluate the acute effect of epirubicin (EPI), an anthracycline anticancer drug, on the evolution of cardiac functional parameters and production of reactive oxygen/nitrogen species (RONS). Isolated perfused rat hearts were subjected to 70 minutes of EPI (10.3 microM) infusion and to 5 minutes of isoproterenol (ISO, 0.1 microM) at the end of the protocol. Coronary flow (CF), left ventricular developed pressure (LVDP), and lactate dehydrogenase (LDH) release in the coronary effluents were evaluated throughout the protocol. RONS were detected in the coronary effluents by electron spin resonance spectroscopy with a spin probe, 1-hydroxy-3-carboxy-pyrrolidine (CP-H, …
Delivery of epirubicin via slow infusion as a strategy to mitigate chemotherapy-induced cardiotoxicity
2017
Background Continuous infusion of doxorubicin has been a strategy to reduce cardiotoxicity. Epirubicin is another anthracycline in common clinical use. However, evidence is lacking regarding whether this strategy can reduce cardiotoxicity of epirubicin without compromising antineoplastic efficacy. Design and methods Healthy rats were randomized into groups: epirubicin (8 mg/kg) delivered intraperitoneally via micro osmotic pumps (MOP), epirubicin (8 mg/kg) by intraperitoneal (IP) bolus injection, and placebo control. Blood samples were collected for analyzing biomarkers of myocardial injury and pharmacokinetics. At chosen times, sub-groups of animals were sacrificed for histopathology. A mo…
Complete long-term survival data from a trial of adjuvant chemotherapy vs control after radical cystectomy for locally advanced bladder cancer.
2005
OBJECTIVES To report the long-term follow-up of patients with locally advanced bladder cancer treated with either adjuvant combined chemotherapy with methotrexate, vinblastine, doxorubicin/epirubicin, and cisplatin (MVAC/MVEC) or no additional treatment after radical cystectomy, to examine various survival endpoints and factors associated with long-term survival. PATIENTS AND METHODS Between May 1987 and December 1990, 49 patients undergoing radical cystectomy for locally advanced bladder cancer were randomized to observation only or adjuvant systemic chemotherapy with three cycles of MVAC/MVEC (methotrexate 30 mg/m2 on day 1, 15 and 22; vinblastine 3 mg/m2 on day 2, 15 and 22; doxorubicin …
Chemotherapy for advanced gastric cancer
2017
Background Gastric cancer is the fifth most common cancer worldwide. In "Western" countries, most people are either diagnosed at an advanced stage, or develop a relapse after surgery with curative intent. In people with advanced disease, significant benefits from targeted therapies are currently limited to HER-2 positive disease treated with trastuzumab, in combination with chemotherapy, in first-line. In second-line, ramucirumab, alone or in combination with paclitaxel, demonstrated significant survival benefits. Thus, systemic chemotherapy remains the mainstay of treatment for advanced gastric cancer. Uncertainty remains regarding the choice of the regimen. Objectives To assess the effica…
Adaptogens in chemobrain (Part I): Plant extracts attenuate cancer chemotherapy-induced cognitive impairment – Transcriptome-wide microarray profiles…
2019
Abstract Background Cancer chemotherapy-induced cognitive impairments are presumably associated with undesirable effects of chemotherapy on physiological functions of brain cells. Adaptogens are natural compounds or plant extracts increasing an organism's adaptability and survival in stress. They exhibited neuroprotective effects and increased cognitive functions in clinical studies in human beings. Hypothesis We hypothesized that selected adaptogenic plant extracts attenuate or prevent cancer chemotherapy-induced cognitive impairments. Aim We assessed the effects of selected adaptogenic herbal extracts on FEC (fixed combination 5-fluorouracil, epirubicin and cyclophosphamide) induced chang…
Correlation between clinical response and urinary interleukin levels using different doses and intravesical administration schedules of interferon-al…
1993
A total of 62 patients at high risk for recurrence of superficial bladder cancer were selected for a study designed to compare the prophylactic efficacy of different doses and schedules of sequential intravesical instillations of epirubicin and interferon-alpha-2b and to evaluate which sequence could enhance the release of cytokines in the urine. Our investigations showed a significant increase in urinary concentrations of interleukins in patients who received the sequential intravesical administration of epirubicin and interferon-alpha-2b. Higher urinary concentrations of interleukins and a lower recurrence rate were detected in patients who received interferon-alpha-2b 24 h after epirubic…
Compatibility of epirubicin-loaded DC bead™ with different non-ionic contrast media
2016
Purpose The aim of this study was to determine the compatibility of epirubicin-loaded DC bead™ with different non-ionic contrast media over a period of seven days when stored light protected under refrigerated conditions. Methods DC bead™ (2 ml) (Biocompatibles UK Ltd) of the bead size 70–150 µm ( = DC bead M1) or bead size 100–300 µm were loaded with 75 mg epirubicin powder formulation (Farmorubicin® dissolved in 3 ml water for injection to a concentration of 25 mg/ml) or 76 mg epirubicin injection solution (Epimedac® 2 mg/ml) within 2 h or 6 h, respectively. After removal of the excess solution, the epirubicin-loaded beads were mixed in polypropylene syringes with an equal volume (∼1.5 ml…
Cisplatin and epirubicin plus oral lonidamine as first-line treatment for metastatic breast cancer: A phase II study of the Southern Italy Oncology G…
1998
Lonidamine (LND) is a unique antineoplastic drug derived from indazole-3-carboxylic acid which inhibits oxygen consumption and aerobic glycolysis, interfering with energy metabolism of neoplastic cells. LND has been experimentally shown to potentiate the cytotoxic effects of epirubicin (EPI) in human breast cancer cell lines, cisplatin activity in both platinum-sensitive and -resistant human ovarian carcinoma cell lines, and EPI antineoplastic activity in some recent phase III trials carried out in advanced breast cancer. A multicenter phase II trial was carried out with the combination of cisplatin 60 mg/m2, EPI 100 mg/m2 and LND 450 mg/day p.o. in three refracted doses/day starting 2 days…
